Ethics-Relevant Values as Antecedents of Personality Change: Longitudinal Findings from the Life and Time Study

What leads personality to develop in adulthood? Values, guiding principles that apply across contexts, may capture motivation for growth and change. An essentialist trait perspective posits that personality changes only as a result of organic factors. But evidence suggests that psychosocial factors also influence personality change, especially during young adulthood. In the Life and Time study of sources of personality change in adulthood, we specifically explore ethically-relevant value priorities, those related to the relative prioritization of narrow self-interest over the concerns of a larger community. According to Rollo May (1967), “mature values”, including aspects of both self-transcendence and self-determination, should serve to diminish or prevent neurotic anxiety. This is consistent with research on materialism, which is associated with lower well-being. An index based on May’s proposal and several related constructs (materialism, unmitigated self-interest, collectivism and individualism) are tested longitudinally as possible antecedents of Big Five/Six personality trait change using bivariate LCMSR models in a national community sample (N = 864 at Time 1). Contrary to an essentialist trait perspective, these value priorities more often preceded change in personality traits than vice-versa. Somewhat consistent with May’s theory, higher “mature” values preceded higher openness (statistically significant at the p < .005 level). Higher vertical individualism significantly preceded lower compassion, intellect and openness. At the suggestive (p < .05) level, higher unmitigated self-interest preceded lower conscientiousness, higher vertical individualism preceded higher volatility, higher mature values preceded higher honesty/propriety and politeness, higher horizontal collectivism preceded higher orderliness, agreeableness, and assertiveness and lower intellect, and higher horizontal individualism preceded lower withdrawal. In two of three cases, suggestive personality-as-antecedent-of-values-change effects were reciprocal with the values-effects: higher conscientiousness scores reciprocally preceded lower unmitigated self-interest, and higher volatility higher vertical individualism. No significant or suggestive “stand-alone”, non-reciprocal personality on values effects were found.

known Schwartz and Rokeach scales of basic human values, and Holland's (1985) model of work values, expressed as interests. Some value-priorities contrasts assess personal preferences, for example the preference for stimulation versus conformity in the Schwartz model, or artistic rather than investigative interests in Holland's model. But ethics and moral virtue are also related to value priorities, for example to the tension between the valuing of the concerns of a larger community over narrow self-interest. The current study focuses on these kinds of values, described also by Thalmayer, Saucier, Srivastava, Flournoy, and Costello (2019). This contrast between broader-scope versus self-focused values is associated with cultural and moral socialization, which presumably continues throughout adulthood. In family life, religious and spiritual traditions, and many other contexts, social influence will encourage concern for others. This is therefore a sector of the values domain in which "maturation" seems especially likely to be ongoing.
Values are not commonly measured as a spectrum from broader-scope to self-focused values. To explore this less familiar domain, value priorities are tested in several ways in the current study. First, they are measured in terms of an index derived from the theoretical writings of Rollo May (1967), who outlined the starting point for a values-driven theory of personality change. In May's view, optimal self-development should include a shift to "mature" values, and this shift would serve to diminish neurotic anxiety. "Mature values" include aspects of selftranscendence like empathy and generosity as well as aspects of self-determination like creativity and freedom. Self-knowledge, independence, and an ethical grounding in compassion and caring for others should come together in an optimally developed, non-neurotic, "mature" person.
This development would logically include broad-minded, compassionate worldview beliefs. A measure of worldview beliefs, capturing the self-focused pole, is also used in this study. The construct of unmitigated self-interest (Saucier, 2000(Saucier, , 2013 encompasses hedonism, materialism, and solipsism. These self-focused, small-minded priorities align with May's view of an undeveloped, immature individual. Relatedly, by May's standards, materialistic values are immature, and this specific aspect of self-focused valuespriorities has been well studied. A meta-analysis of 151 studies from around the globe confirms their consistent association with lower well-being (Dittmar, Bond, Hurst & Kasser, 2014). Longitudinal studies show similar associations .
Finally, collectivism and individualism measures (Triandis & Gelfand, 1998) also concern value-priorities (Oyserman, Coon, & Kemmelmeier, 2002), though their association with personality development is not yet well explored. Individualists prioritize independence, personal freedom (from constraints placed by others), uniqueness, and self-determination. The relation with self-focus is clearest when these are further defined in terms of degree of hierarchy. Vertical individualism, the most self-focused component, indicates a value for autonomy in an unequal world in which individuals compete for status, whereas horizontal individualism indicates a value for autonomy in a more equal world of unique, independent, and selfreliant individuals. Collectivists value duty, obligation, social harmony, and self-transcendence (Le & Levenson, 2005), and both components in terms of hierarchy appear to capture broader-scoped values: Vertical collectivism indicates a focus on duties to family or other in-groups where some have more authority than others, whereas horizontal collectivism indicates valuing relationships with peers who are more or less one's equal (Triandis & Gelfand, 1998).
These values constructs -materialism, immature values, unmitigated self-interest, and individualism -overlap. All (with the exception of horizontal individualism) can indicate either moral engagement with a broader community or self-focused priorities. In terms of the wellknown Schwartz values types, they represent prioritization of hedonism and power over benevolence, and more broadly of self-enhancement over self-transcendence.

Value change across the lifespan
In a previous study, this set of broader-scope versus selffocused values was largely stable over a three-year period, with some age-normative shifts: People on average became less self-focused with increasing age, and women had slightly less self-focused values than men (Thalmayer et al., 2019). These findings are consistent with the substantial mean-level, rank-order, and longitudinal stability established for the popular Schwartz Values Scale (Bardi, Lee, Hofmann-Towfigh, & Soutar, 2009;Milfont, Milojev, & Sibley, 2016;Vecchione et al., 2016;Vecchione, Alessandri, Roccas, & Caprara, 2018), which considers relative priorities among 10 or 11 values proposed to derive from four universal requirements of human existence (Schwartz, 1992). Schwartz's model differs from the constructs explored in the current study by being a broader model of human motivations, less specifically focused on the contrast of ethically-relevant values, although results based on that model have been used to address such questions. For example, Silfver, Helkama, Lönnqvist, and Verkasalo (2008) reported that guilt-proneness and empathy were positively related to self-transcendence values (universalism, benevolence, tradition, and conformity), and negatively to selfenhancement values (power, hedonism, stimulation, and self-direction); much like the pattern found for associations with moral sensitivity (Myyry & Helkama, 2002). And Schwartz and Bardi (2001) found that values of benevolence and universalism, the most morally-relevant of the 10 Schwartz value types, were the most highly endorsed across diverse societies.
Although the emphasis is on normative changes rather than optimal development or personal growth, as in May's theory, the empirical evidence supports a general trend away from self-focus and toward broader-scoped value priorities with age. Milfont and colleagues (2016), who administered a measure of Schwartz values one year apart for three years to a sample of adults in New Zealand, reported greater endorsement of conservation and selftranscendence and less endorsement of openness and self-enhancement values for older participants. Gouveia and colleagues (2015) reported higher interpersonal and normative scores and lower excitement and self-promotion for older participants on the Basic Values Survey (BVS) in a large cross-sectional Brazilian sample. Robinson (2013) reported higher tradition and conservative values and lower stimulation and openness to change values in older participants in a large pan-European sample. (Such studies, of course, cannot distinguish typical change with age from cohort effects).

Personality change and development
The influential Five Factor Theory (e.g. McCrae & Allik, 2002) conceives personality as fixed, with the basic tendencies underlying phenotypic traits only changing as a result of organic factors, such as physical aging, brain injury, or medications. Substantial recent empirical evidence, however, indicates a degree of personality change across the lifespan, in addition to significant stability. Cross sectional studies of Big Five traits demonstrate predictable age differences -older people are, on average, more agreeable, conscientious and emotionally stable than younger ones (Soto, John, Gosling, & Potter, 2011). A meta-analysis of 92 longitudinal studies has similarly shown individuals to increase in conscientiousness, emotional stability and social dominance (extraversion) in young adulthood, then later to increase in agreeableness and decrease in social vitality (extraversion) and openness (Roberts, Walton, & Viechtbauer, 2006).
What leads individuals to change? Social investment theory posits that people develop more adaptive traits through commitment to and socialization into social roles, which are often age-normative (Lodi-Smith & Roberts, 2007). This theory is supported by cross cultural evidence that normative personality differences appear at younger ages in cultures with an earlier onset of adult role-responsibilities, in particular earlier transition to the labor force (Bleidorn et al., 2013). Additionally, clinical interventions have been seen to effectively change personality traits  provide a metaanalysis of 207 studies).
Another possible source of personality change is an individual's values. A role for value priorities as an influence on personality is consistent with Dweck's (2017) integrative theory of motivation, personality, and development. In this theory, basic needs for acceptance, predictability, and competence drive behavior from early in life, by animating goals designed to meet basic needs. Pursuit of needfulfilling goals leads to mental representations, which guide future goals and create characteristic, recurrent patterns of behavior i.e., personality traits. In contrast to Five Factor Theory, this theory posits that while temperament can impact social-cognitive processes, it is social-cognitive processes that play the leading role in affecting behavior patterns. Personality change and development is driven by mental representations, including value priorities as a form of motivation. For example, to meet the basic need for acceptance, materialistic values could lead one to dress and live in a way that conveys status; the need for predictability is then met by having concrete, literal markers for self-worth and how rewards are achieved.
Acceptance could instead be sought by someone with "mature values" in terms of self-acceptance. Competence, control, self-esteem, and self-coherence could be sought by this person by pursuing self-actualization in a way that includes both personal autonomy and empathic concern for others.
In summary, while personality was once theorized to be static during adulthood, contemporary research suggests that some amount of change and development is to be expected. Two sources of change supported by empirical evidence are social-role investment and clinical interventions. Another possible source of change, explored here, is individuals' ethical-value priorities.

Values and Personality
The broader-scope versus self-focused values of interest in this project -materialism, immature values, unmitigated self-interest, and individualism -appear to be largely distinct from Big Five and Big Six personality traits. As reported by Thalmayer and colleagues (2019), the exceptions are moderate positive correlations between the mature values index and openness (around .43 on average), and between the moderately intercorrelated (magnitudes of .33 to .49) set of values measures -horizontal and vertical collectivism and the mature value index, versus vertical individualism and materialism -with honesty/propriety and agreeableness (.19 to .56 in magnitude).
This is similar to correlational findings reported for the Schwartz values. In a meta-analysis of 60 studies using the Five-Factor Model of personality traits and Schwartz values, Parks-Leduc, Feldman and Bardi (2015) report consistent and theoretically meaningful relationships but with small to medium effect sizes. Overall, the traits that might be thought of as more cognitively based, especially openness to experience, followed by agreeableness, extraversion, and conscientiousness, were more strongly related to values than the arguably more emotionally based traits like emotional stability. Another meta-analysis of correlations between Big Five traits and Schwartz values from 14 countries again reported associations between higher Big Five openness and agreeableness and values scales (specifically with lower conservation and higher self-transcendence, respectively; Fischer & Boer, 2015). Trait-value associations, however, were seen to be stronger in countries with more democratic institutions and permissive social contexts, and weaker in those with greater financial, ecological, and social threats (Fischer & Boer, 2015).
The influence of personality traits and values variables on each other over time has only recently been examined. Fetvadjiev and He (2018) reported their mutual effects using a broader set of values constructs than those selected for the current study, in a nationally representative panel from the Netherlands, tested five times over eight years. They found that Big Five traits measured by the 50-item IPIP measure predicted change in Rokeach values more strongly than vice versa; personality traits also predicted well-being and self-esteem more strongly than did the values. Similarily, Vecchione and colleagues (2018) tested the mutual effects of the 10 Schwartz values and Big Five personality traits among Italian young adults assessed three times over 12 years. They found that while this set of values (also much less specific than the value-priorities measured in the current study) did not affect trait development, high agreeableness predicted an increase in benevolence values, and high openness an increase in self-direction values.

Goals for the current study
Recent research indicates that personality change occurs throughout the lifespan, though the sources of such change are not yet fully understood. Here we test ethicallyrelevant, broader-scope versus self-focused values as antecedents of, and alternatively as potential outcomes of personality trait change, with four measurements over three years in a diverse national sample.
This study tests two competing hypotheses. The "null model" represented by Five Factor Theory (McCrae & Costa, 1999), is that effects of traits as antecedents to changes in values will tend to be larger than the effects of values as antecedents to changes in traits. This null model, in which traits are causes and not effects, was recently supported by findings with other types of value-priorities by Fetvadjiev and He (2018) and Vecchione and colleagues (2018). The other hypothesis, that indicators of immature values and worldviews (unmitigated self-interest, materialistic values) will precede and predict increased neuroticism, whereas broader-scoped, "mature" values would lead to decreased neuroticism, is based on May's theoretical proposal and on previous literature, primarily for materialism. We extend this hypothesis more broadly to what might be argued as "unfavorable change" among other personality traits, specifically lower conscientiousness (like neuroticism, a trait targeted for clinical interventions; Roberts, Hill, & Davis, 2018), and pro-sociality in terms of lower agreeableness and honesty/propriety. Another logical expectation would be that collectivism would associate with higher scores on traits related to social self-regulation (conscientiousness, agreeableness, honesty/propriety), and individualism with traits related to dynamism (extraversion and openness).

Methods
The Life and Time study grant application, which details all hypotheses for the overall study, is available at https://osf.io/bdseu/, along with study materials, data, and code and output for all analyses. The Life and Time Study is a four-wave, three-year longitudinal study on values and social roles as sources of personality change, including three separate samples: a national sample recruited via Mechanical Turk, an e-mail marketing firm, Google Adwords, and Craigslist ads in communities around the United States whose demographic profile was favorable to enhancing minority representation; a student sample recruited on college campuses; and a sample of informants recruited by participants to provide peer-ratings on themselves. The study was reviewed by the Office for the Protection of Human Subjects of the University of Oregon in 2009.

Participants
A total of 879 individuals representing all major geographical regions of the Unites States, joined the Life and Time Study national sample. From the full sample, 10 cases were dropped due to impossible age variations across the waves (beyond a typo that affected only one of three or four otherwise consistent responses) suggesting an insincere participant, and five because the participant did not report age (final sample N = 864; 66% female). Of these, 628 provided data at Time 2, 594 at Time 3, and 578 at Time 4. Some participants did not answer all scales at all waves; the minimum sample size for each wave is 862 (Time 1), 619 (Time 2), 590 (Time 3), 573 (Time 4). The age of participants at Time 1 (in the year 2010) ranged from 18 to 63 (M = 36, SD = 10.5). The ethnic composition of the sample was similar to that of the general United States population: 71% non-Hispanic White, Caucasian, or European-American; 12% Black or African-American; 8% Hispanic, Latino, or Spanish; 5% Asian or Asian-American; 2% American Indian or Alaska Native; 1% Native Hawaiian or other Pacific Islander. For more details, including geographical regions and education level, see Thalmayer et al. (2019).

Procedure
Recruitment is described in further detail in Thalmayer et al. (2019). At each wave, participants were emailed a link to a website to complete a battery of self-report questionnaires, including two personality scales, described below, and values, aspirations, worldviews, goals, life events, and relationship, work, and life satisfaction items. Participants were compensated with a gift card for $20-40 (increasing across waves) to an internet retailer after completing surveys. Participants could opt to receive a check in the mail instead. Analyses of Big Five and Big Six rank-order stability, mean-level change, and measurement invariance in the Life and Time national sample are reported in Costello, Srivastava, and Saucier (2017).

Materials
The Life and Time study focused on personality change during adulthood. Values-scales related to May's concept of mature values were included as hypothetical predictors of personality change. We report on the full set of values variables included in the study, detailed in Table 1. Note that personality traits were measured using both the Big Five and Big Six models of personality; although the Big Five is the most common way to measure normal-range personality attributes, the Big Six has been proposed as an update to the model as it appears to be more replicable across lexical studies in diverse languages (Saucier, 2009). The most significant difference between the models is the addition of a dimension with content related to moral and ethical behavior and to adhering to prosocial norms. Whether the variable selection is relatively narrow (e.g., Ashton et al., 2004) or inclusive (e.g., Saucier, 2009), this sixth "honesty" dimension tends to arise in studies of the natural language, indicating social importance across diverse cultural settings. While the two models are highly similar, the Big Six has demonstrated an advantage in  , 1999). Minimum, maximum, mean, standard deviation, and age and gender correlations are at Time 1. r retest is an average of retest correlations between years 1 and 2, 2 and 3, and 3 and 4. r t1,t4 is the Time 1 to Time 4 retest correlation. For correlations with age and gender, bolding indicates p < .01. 1 This scale was scored by averaging the 10 forward-keyed and the 7 reverse-keyed items separately, then transforming each into percent of maximum possible (POMP) scores. These two subscales were then averaged for the final scale. The mean, however, was calculated on the full set of items entered as a single group.

Big Five Inventory (BFI)-Six
Personality traits were measured with the 44-item BFI (John, Naumann, & Soto, 2008) plus a 16-item addendum to create a six-factor version (as in Thalmayer et al., 2011). The addendum includes an honesty/propriety scale drawn largely from the Questionnaire Big Six (Saucier, 2009;Thalmayer et al., 2011), similar to the Honesty/Humility factor in the HEXACO (Ashton & Lee, 2007). Items on this scale included: "is not good at deceiving other people", "sticks to the rules", "uses others for my own ends", "takes risks that could cause trouble for me", "misrepresents the facts", "has bad manners", "uses flattery to get ahead," and "would never take things that aren't mine." The BFI-Six also includes an alternative agreeableness (B6) scale (as in Thalmayer et al., 2011), with more content related to lack of short-temperedness and irritability than typical Big Five agreeableness. Items were rated on a scale from 1 to 5, with higher numbers indicating greater agreement.  (Diamantopoulos & Papadopoulos, 2010). For this reason we did not evaluate it for measurement invariance, and therefore cannot rule out the possibility that any differences across age reflect differences in the performance of the instrument across age groups.

Unmitigated Self-Interest
This 6-item scale (Saucier, 2000(Saucier, , 2013Thalmayer et al., 2019; α = .67), measures hedonism, materialism, and solipsism, using a 5-point Likert-type scale from strongly disagree to strongly agree, with half the items reverse-keyed. Example items include: "The pleasures of the senses are the highest good," and "People ought to be motivated by something beyond their own self-interest." Although these might be read as statements of beliefs, they involve strong valuations placed on pleasure, material possessions, and self-interest. As regards solipsism, if nothing outside the self exists, it follows that nothing outside the self has value.

Materialism
This 6-item scale is derived from items in Richins and Dawson's (1992) scale of materialistic values, based on item reduction efforts (Shen-Miller, 2009;Shen-Miller, Saucier & Pan, 2015), as described in Thalmayer and colleagues (2019; α = .80). Half the items were reversekeyed and all are answered on the same 5-point Likerttype scale as BFAS items, from extremely inaccurate to extremely accurate in terms of describing oneself. Example items include "Would be happier if I could afford to buy more things" and "Don't pay much attention to the material objects other people own."

Financial Aspirations
Aspirations for Financial Success (Kasser & Ryan, 1993; α = .80) is one of five scales on a 23-item inventory of aspirations. The scale includes five items worded in the second person (e.g. "You will buy things just because you want them") rated on a 5-point Likert-type scale from "not at all important" to "very important". This scale was meancentered using the four scales administered.

Individualism and Collectivism
In the scales provided by Triandis and Gelfand (1998), individualism and collectivism are both split into two components, as described above. Each of the four subscales was measured with four total items, all keyed in the same direction, and all answered on a 5-point Likert-type scale from strongly disagree to strongly agree (α = .56 to .71).

Analyses
Reciprocal relations between personality and values scales were tested using bivariate latent curve models with structured residuals ( (2015), confounds within-and between-person covariance because it does not account for trait-like stability. The LCM-SR effectively decomposes covari-ance into between-person trait-like linear stability (as instantiated in the latent curve component of the model) and within-person wave-to-wave auto-regression as well as reciprocal, lagged influences from one construct to the other (which is accomplished by modeling the residuals from the LCM using the traditional CLPM structure). Each of the BFI-Six scales and ten BFAS scales was tested separately in relation to each of the eight values scales, in all tests accounting for age, using Mplus 7 (Muthén & Muthén, 2012), with robust maximum likelihood estimation (MLR). See Figure 1 for an example of the model. Interpretation focuses on crosslagged coefficients for regression of subsequent personality score on previous values scores, and subsequent values on previous personality score, which indicate the extent to which values influence personality traits over time and vice versa. Within-wave (within-person) intercept correlations are also interpreted as a way to separate within-and between-person variance, a strength of LCM-SR (Curran et al., 2014;Hamaker, Kuiper, & Grasman, 2015). These residual correlations account for individual differences in trait-levels and linear trends in trait-levels, and for levels during previous waves. Non-zero correlations indicate within-person processes linking fluctuations in responses to personality and the values indicators, and provide a way to address state versus trait variation. Following Benjamin and colleagues (2018), we define results with a false positive rate under the null hypothesis less than 5% (alpha = .05) as "suggestive", and only those with a false positive rate under the null hypothesis less than 0.5% (alpha = .005) as "statistically significant". We also provide supplementary tables with all within-person cross-lagged and contemporaneous coefficients and p-values corrected to control the family-wise error (FWE) rate across all tests within direction (e.g., lagged valuesto-personality; k = 128) at α = .05 (Holm, 1979), and to control the false discovery rate (FDR) at q = .05 (Benjamini & Hochberg, 1995).
The measurement invariance of the values scales (with the exception of the mature values index, as discussed above) across four age groups corresponding to decades, participants in their 20s (N = 304), 30s (N = 227), 40s (N = 199), and 50s (N = 132), is described in Thalmayer and colleagues (2019). The measurement invariance of the personality scales across the age groups is described in Costello and colleagues (2017). Because changes in McDonald's non-centrality fit index (MFI; McDonald, 1989) exceeded the threshold for assuming perfect measurement invariance for the values scales other than horizontal individualism, we used modified scales as in Thalmayer and colleagues (2019) to test the sensitivity of results to measurement issues. Comparisons of the results reported below and those found for the modified-to-be-invariant values scales (all available in supplemental materials) indicated that the directions and size of the cross-lag coefficients were generally highly similar, with a mean absolute difference of 0.017, SD = 0.014 (range from 0 to 0.085) and mean absolute coefficient estimate of 0.039, SD = 0.035. The mean absolute difference for significant (p < .005) crosslag coefficients was 0.021, SD = 0.011 (range 0.010 to 0.033), with mean absolute coefficient estimate of 0.110, SD = 0.058. Finally, across all suggestive (p < .05) crosslag coefficients, mean absolute differences was 0.021, SD = 0.015 (range 0.000 to 0.057), with mean absolute coefficient estimate of 0.11, SD = 0.046. Interpretation proceeds solely with the a priori scales, but direct comparison of all significant and suggestive coefficients can be found in the supplemental materials.

The Reciprocal Influence of Value Priorities and Personality Change
Coefficients for the cross-lagged effects are described below and are reported in Tables 2 to 9. Significant crosslag coefficients indicate associations between values and personality scales from earlier to later waves over and above the average linear change across waves for each scale, as well as over and above expectations due to an individual's previous-wave score. That is, a significant cross-lagged regression path of values on personality indicates that a deviation from these expectations on a values scale tends to precede an associated deviation in the personality scale in later waves. A significant crosslagged path of a regression of personality on values indicates that a deviation from expectations on a values scale precedes a deviation on a personality scale. These cross-lagged effects are separate from the between- Autoregressive paths are fixed to be equal between waves for the value (a) and personality (b) variables. Cross-lagged paths are also fixed to equality both for personality SRs regressed on value SRs (c) and value SRs regressed on personality SRs (d). The within-wave correlations of SR residuals are fixed to equality for the last three waves (e).
person intercept-to-intercept correlations that are also shown in the tables. These indicate between-person associations in mean level, separate from the crosslagged associations due to within-person perturbations. Note that it is possible for a values scale to show positive intercept-to-intercept correlation with a personality scale while simultaneously showing a negative cross-lagged regression effect. Results including all parameter estimates, including those for scales modified to achieve measurement invariance, are available in supplementary materials. These include within-person values-to-values and personality-to-personality auto-regressive associations between structured residuals (residuals after accounting for a linear growth curve mean structure), within-person, within-wave values to personality correlations between residuals of the structured residuals after accounting for the association between the previous wave's personality and values residuals, and between-person correlations between individual differences in the growth-curve slopes.

Unmitigated self-interest
Higher unmitigated self-interest scores preceded lower conscientiousness scores, and reciprocally, higher conscientiousness scores preceded lower unmitigated self-interest scores. These results were statistically suggestive, at p < .05, rather than significant, at p < .005 (see Table 2). Between-person growth-curve intercept correlations were significant and negative for honesty/propriety, agreeab-leness (B6), compassion, politeness, openness, intellect and BFAS openness, while they were suggestive and positive for volatility and extraversion.

Vertical Individualism
Higher vertical individualism significantly preceded lower compassion and BFAS intellect and openness scores (see Table 3). At the statistically suggestive level, vertical individualism and volatility scores reciprocally preceded each other and higher vertical individualism preceded lower BFI openness. Between-person growthcurve intercept correlations were significant and negative for honesty/propriety, agreeableness (B6), compassion, politeness, neuroticism, and BFAS openness, significant and positive for assertiveness, and suggestive and positive for volatility and extraversion.

Financial Aspirations
Between-person growth-curve intercept correlations were significant and negative for honesty/propriety, agreeableness (B6), compassion, politeness, enthusiasm,  openness, intellect and BFAS openness, significant and positive for volatility, and assertiveness, and suggestively positive for orderliness (see Table 5).

Mature Values Index
Higher mature values significantly preceded higher BFAS openness scores, and suggestively preceded higher honesty/propriety and politeness (see Table 6).
Between-person growth-curve intercept correlations were significant and positive for honesty/propriety, agreeableness (B6), compassion, politeness, openness, intellect, and BFAS openness. They were significant and negative for orderliness, and suggestive and negative for volatility.
Between-person growth-curve intercept correlations were significant and positive for conscientiousness, industriousness, honesty/propriety, agreeableness (B6),   compassion, politeness, extraversion, enthusiasm, and BFAS openness. They were significant and negative for neuroticism, volatility, and withdrawal. They were suggestive and positive for orderliness, assertiveness, openness, and intellect.

Horizontal Individualism
Higher horizontal individualism scores suggestively preceded lower withdrawal scores (see Table 9).
Between-person growth-curve intercept correlations were significant and negative for agreeableness (B6) and significant and positive for assertiveness, openness, intellect and BFAS openness. They were suggestive and positive for conscientiousness and industriousness, and suggestive and negative for compassion, politeness, and enthusiasm.
In sum, Tables 2 through 9 show no statistically significant but three suggestive personality-as-antecedentto-values change cross-lag coefficients. These tables show four statistically significant and ten suggestive valuesantecedent-to-personality-change coefficients. One coefficient survives FWE-correction (α = .05; vertical individualism proceeding compassion), and three coefficients survive FDR-correction (q = .05; vertical individualism proceeding compassion, intellect, and the BFAS openness; see supplementary materials). It would thus be difficult to conclude that changes in values are systematically downstream of personality attributes (rather than the other way around) as an essentialist trait theory would predict.

Discussion
The current study explored the reciprocal contributions of Big Five/Six personality traits and value-priorities that contrast self-interest with broader concern in a longitudinal sample tested annually on four occasions. These analyses allow us to explore this type of value priorities as a source 1 of personality change in adulthood. Theories involving essentialist trait concepts such as Five Factor Theory would posit that personality will affect values over time, but values cannot influence personality. Our results present a different picture, with more significant or suggestive effects for values impacting downstream personality scores, as compared to personality traits preceding change in values scores. These results match a common-sense view of motivation and behavior, in which value-priorities should be upstream, influencing the behavioral patterns captured by personality trait measures. They are also consistent with Dweck (2017), with value priorities, as a form of motivation, influencing behavior by shaping goals and mental representations. However, the results do not provide a strong counter claim to Five Factor Theory, as overall the cross-lagged associations were small, and a trait essentialist could argue that the influence of traits on values will have already been solidified and thus would not be apparent in a relatively short longitudinal design.
The specific influences of values on personality were consistent with our expectations that higher scores on self-focused (immature, materialistic) values would precede and predict unfavorable change in personality traits. Our most robust effects, those that achieved statistical significance at the p < .005 level, included vertical individualism preceding lower compassion, intellect and BFAS openness, and higher mature values index scores preceding higher BFAS openness. At the suggestive (p < .05) level, higher unmitigated selfinterest preceded lower conscientiousness, higher vertical individualism preceded higher volatility, higher mature values preceded higher honesty/propriety and politeness, higher horizontal collectivism preceded higher orderliness, agreeableness (B6), and assertiveness and lower intellect, and higher horizontal individualism preceded lower withdrawal. In two of three cases, suggestive personality-as-antecedent-of-values-change effects were reciprocal with the above noted valueseffects: higher conscientiousness scores reciprocally preceded lower unmitigated self-interest, and higher volatility higher vertical individualism. No significant or suggestive "stand-alone", non-reciprocal personality on values effects were found.
The relation between mature values and openness is unsurprising, given May's emphasis on creativity and broad-mindedness. That higher mature values scores preceded higher honesty/propriety and politeness is also consistent, given the emphasis on generosity, empathy, and unselfishness. However, contrary to May's theoretical formulation forged from a career as a psychotherapist, there were not strong associations with neuroticism and its aspects. This is consistent with meta-analytic results indicating a lack of association between neuroticism and the Schwartz values (Fischer & Boer, 2015;Parks-Leduc et al., 2015), from which stimuli our mature values index was scored. While the cross-lag associations were in the expected directions, they were only large enough to reach thresholds for statistical significance in the case of vertical individualism with volatility. It is conceivable that early psychologists, like May and others of the existentialisthumanist tradition, sometimes valued openness to the extent that they took it to indicate psychological health (e.g., Miller, 1991). However, while this trait is related to interest in psychotherapy (Miller, Pilkonis, & Mulvey, 2006;Soldz & Vaillant, 1999) and personal development and growth generally (DeYoung, Peterson & Higgins, 2005) it does not appear to be related to psychological disorders (e.g., Kotov et al., 2010;Malouff, Thorsteinsson, & Schutte, 2005).
An additional expectation was that collectivism would lead to downstream effects on traits related to social self-regulation, and individualism with traits related to dynamism. Consistent with this, vertical individualism preceded lower compassion and higher volatility, but it also predicted lower openness and intellect, suggesting that these aspects of dynamism are not increased by a competitive, individualistic point of view. Interest in being an original, curious, inventive deep thinker, with aesthetic and artistic aspirations, may be crowded out when one is focused on out-competing others. And while horizontal collectivism preceded higher social self-regulation-related traits like orderliness and agreeableness (B6) and lower dynamism-related intellect, it also, more surprisingly preceded the dynamic trait of assertiveness.
It is of interest that mature values -a composite variable lacking standard psychometric strengths -plays a salient role in these results, as a predictor of personality change and one that captures some variation in effects across the adult lifespan. This suggests the utility of composite measures in prediction. It also underscores the potential of hypotheses drawn from existential psychology.
Note that the strongest relations in Tables 2 to 9 are those between the latent intercepts. This implies that the relations between values and personality traits were in many ways pre-existing, rather than being reciprocally caused by each other's dynamic perturbations. This is consistent with the idea that though there is some change over the lifespan, personality traits and values are characteristics that spring from similar, early developmental sources. The most robust of these (significant at the p < .005 level) include positive associations between the conscientiousness scales, including industriousness and in one case orderliness, with collectivism scales. Orderliness was also positively associated with higher materialism and lower mature values. Higher honesty/propriety, agreeableness (B6), compassion, and politeness were all associated with lower unmitigated self-interest, vertical individualism, materialism, and financial aspirations (plus horizontal individualism in the case of agreeableness) and with higher mature values and collectivism. Neuroticism, volatility and/or withdrawal were positively associated with financial aspirations and materialism but negatively with vertical individualism and horizontal collectivism. Higher openness, intellect and/or BFAS openness were associated with lower unmitigated self-interest, vertical individualism, financial aspirations, and materialism, and higher mature values, horizontal collectivism and horizontal individualism. Extraversion was positively associated with horizontal collectivism and financial aspirations, assertiveness with both individualism scales, and enthusiasm with financial aspirations and both collectivism scales.
It is important to consider how our results, especially our finding that values variables had a stronger downstream impact on personality traits than vice versa, have to do with the specific type of ethicallyrelevant values we measured, rather than to values as a general class. Fetvadjiev and He (2018) and Vecchione and colleagues (2018) both instead reported greater longitudinal impacts of traits on values. However, both of these studies used broad measures of values, Rokeach's in the former and the Schwartz scale in the latter. While the mature values index is made of items from these scales (though seven of its 17 items are not in the Rokeach survey), this index intentionally includes content from the two dimensions these broader scales contrast: both self-determination and self-transcendence. May's theory suggested the benefits, though not the typicality, of embracing elements of both domains. It is even harder to compare the broad Rokeach and Schwartz values scales to the other indicators used in the current study. Unlike these recent European studies, we did not plan this project as a comprehensive assessment of the relation of all values to personality change; we instead sought to test a more specific hypothesis about the role of ethics-relevant values, a hypothesis which received some support from the findings reported here. Morally relevant values may reflect a channel of cultural socialization toward what society considers proper behavior well into adulthood. This may not be true for other types of values, some of which simply contrast different interests.
One interesting point of convergence between our studies involves the personality traits that Vecchione and colleagues (2018) observed as being predictors of values change. In their results, high agreeableness predicted an increase in benevolence values, and high openness an increase in self-direction values. Our findings were that aspects of personality related to agreeableness and openness were the ones most affected downstream by the ethically-relevant values variables we studied. These two personality dimensions may be more values-related or values-responsive than other Big Five dimensions.
A limitation of the current study, true to most observational research, is the possibility that both contemporaneous and lagged effects are driven by unobserved variables, for example, changes in income. In the case of lagged effects, it is possible that a change in an unobserved variable first has consequences for a more malleable variable (e.g., a value) and also, later on, for a less malleable variable (e.g., a personality dimension). Another limitation was the short time-frame. Although the study covered the full range of adulthood, each subject was only followed for three years. A longer period would be ideal to capture the small but potentially steady change and development that occurs in both value priorities and personality traits over the life course. A longer study period would also better allow for the disentangling of cohort from age effects.

Conclusion
This study explored a set of value priorities relevant to ethical behavior as predictors of change in Big Five and Big Six personality traits in a national sample of adults. Contrary to an essentialist trait perspective, personality attributes did not have more downstream influence on values than vice-versa. Instead higher scores on broader-scoped, as opposed to self-focused (immature, materialistic), values preceded and predicted favorable change in personality traits in terms of increased openness, honesty/propriety, conscientiousness and agreeableness and its aspects, and decreased volatility and withdrawal.

Note
1 This research was motivated by a causal theory, and we attempt in this discussion to be transparent about that. Although the study was not a randomized trial, longitudinal observational designs and analyses like that presented here are intended to draw inferences about causality, with awareness of assumptions and limitations. As Hernán (2018) argues, avoiding causal language entirely forces authors of observational studies to be euphemistic or roundabout about their goals, which generates confusion.
