Relation between resilience and personality traits: The role of hopelessness and age

Resilience refers to the process by which individuals use the ability to cope with challenges to successfully adapt to adverse situations, inclining towards the future and hope. The main aim of this study was to analyze the relation between resilience, personality traits, and hopelessness. Furthermore, we conducted comparisons between two age groups: young and older adults. The sample comprised 439 Spanish participants (66.7% women; M = 43.73, SD = 26.41; age range = 18–98 years). The Connor–Davidson Resilience Scale, NEO‐Five Factor Inventory, and Beck Hopelessness Scale were used to measure the main study variables. The results revealed a negative relation between resilience and neuroticism, and a positive association with the other personality traits. Additionally, levels of resilience were found to be negatively related to hopelessness. The group of older adults showed significantly lower resilience levels than the young adults, although age was not a significant predictor of resilience. Neuroticism, extraversion, openness, and hopelessness were the only predictors of resilience for the current study. This work contributes to the study of resilience and related factors, by attempting to understand the role of resilience and resistance to risk and how individuals tackle challenges over time, with important implications for mental health.


INTRODUCTION
Mental illness is one of the main causes of disability around the world (World Health Organization, 2022). It affects not only the lives of patients but can also have a lasting impact on their immediate environment and society (World Health Organization, 2019). Stressful experiences, such as trauma, life changes, wars, illness, or pandemics have been considered risk factors for mental health (e.g., Bryant, Schnurr & Pedlar, 2022;Harnett, van Rooij, Ely et al., 2021;Willey, Mimmack, Gagliardi et al., 2022;Zhu, Zhang, Zhou, Li & Yang, 2021). However, it is also worth noting that many people exposed to stressful situations recover quickly or suffer no significant psychological and functional deterioration (Bonanno, Westphal & Mancini, 2011;Kalisch, Baker, Basten et al., 2017). There may be many reasons for this, among which resilience has been highlighted as a key trait in achieving good mental health (F€ arber & Rosendahl, 2020).
Resilience refers to the process by which people use the ability to cope with challenges and new circumstances to positively adapt to adverse contexts, leaning towards the future and hope (Barton, McKay, Garvis & Sappa, 2020;Murphy, 1987). Likewise, it is about a multidimensional construct determined by intrinsic and extrinsic factors that underlie an individual's cognitive, social, emotional, behavioral, and psychological functioning (Malhi, Das, Bell, Mattingly & Mannie, 2019;Masten, 2015). Focusing on the intrinsic approach, resilience can be presented as a trait that moderates the negative impact of stress and facilitates adaptive development (Connor & Davidson, 2003;Ong, Bergeman, Bisconti & Wallace, 2006). Trait-resilience has been commonly operationalized using the Connor-Davidson scale (CD-RISC; Connor & Davidson, 2003). More specifically, the CD-RISC assesses personal characteristics, such as self-efficacy and optimism, which can be effective in adequately managing stress and enhancing adaptive development (Rodr ıguez, Alonso & Hernansaiz, 2016).
Resilience is a construct that has been studied in different perspectives (Bonanno et al., 2011;Salisu & Hashim, 2017;Southwick, Bonanno, Masten, Panter-Brick & Yehuda, 2014). One such perspective focuses on resilience as personality characteristics that manifests itself in response to life circumstances and individual profiles (Cloninger & Zohar, 2011;Connor & Davidson, 2003;Oshio, Kaneko, Nagamine & Nakaya, 2003). These profiles reflect an individual's characteristic thoughts, feelings, and behaviors, namely, personality (Wagner, L€ udtke & Robitzsch, 2019). The Five-Factor Model is typically taken as the reference when operationalizing personality (Costa & McCrae, 1992). This model comprises five broad categories, namely, neuroticism, extraversion, openness, agreeableness, and conscientiousness. Personality traits tend to remain stable over the lifespan, although they may undergo changes as a result of maturation processes and life experiences. In this sense, it has been suggested that neuroticism and extraversion decrease with age, while agreeableness and conscientiousness increase across the lifespan. Generally, openness increases in adolescence and declines in aging (Costa, McCrae & L€ ockenhoff, 2019).
Resilience could be the key to explaining resistance to risk and the way people cope with challenges across the lifespan (F€ arber & Rosendahl, 2020). However, age-related differences in resilience are not yet conclusive. While some studies have reported that as people age, they become more resilient (Campbell-Sills, Forde & Stein, 2009;Gillespie, Chaboyer & Wallis, 2009), others have shown a negative relation between resilience and age (Beutel, Glaesmer, Decker, Fischbeck & Br€ ahler, 2009;Lamond, Depp, Allison et al., 2008). Even in recent reviews, no significant associations have been found between these variables (F€ arber & Rosendahl, 2020;Lee, Nam, Kim, Kim, Lee & Lee, 2013). Indeed, it seems that the results are still inconclusive, due mainly to methodological aspects, such as the existence of a wide range of evaluation instruments, covariates, and sample characteristics (Lee et al., 2013;McGinnis, 2018;Pulido, Fern andez & Lopez, 2020).

THE CURRENT STUDY
In light of the above, resilience seems to be a significant construct for the promotion of health and prevention of mental illnesses because it could help people recover, maintain, and improve their psychological well-being when they have been exposed to stressful experiences (F€ arber & Rosendahl, 2020;Ungar & Theron, 2019). Furthermore, the study of resilient individuals and the mechanisms that protect them is a strategy recommended to combat stress-related diseases (Kalisch et al., 2017). Considering that individuals' responses to stressful situations are the result of a complex interaction of factors, including personal characteristics (Biggs, Brough & Drummond, 2017), this work aims to complement the existing literature about variables related to resilience, focusing on analyzing the relations between resilience and personality traits in a sample of Spanish adults. Additionally, the role of hopelessness and age were examined on resilience capacity.

Participants
The participants were a convenience sample comprising 439 Spanish adults (66.7% women; M = 43.73, SD = 26.41; age range = 18-98 years) recruited from public institutions: universities, universities for older adults, seniors' associations, and community centers. The participants were Spanish speakers and were of medium-high socioeconomic status. The sample was divided into two groups: young adults (n = 227; 81.9% women; M = 19.86, SD = 1.30; age range = 18-24 years) and older adults (n = 212; 50.5% women; M = 71.37, SD = 8.76; age range 60-98 years). Inclusion criteria were: (1) being literate; (2) for the older group, having no cognitive difficulties. Cognitive impairment was tested using the Mini-Mental Status Examination (Lobo et al., 2002); and (3) giving signed informed consent. Following these criteria, five participants were excluded for presenting scores compatible with cognitive impairment. NEO-Five factor inventory. Neuroticism, extraversion, openness, agreeableness, and conscientiousness were assessed using the Spanish version of the NEO-Five Factor Inventory (NEO-FFI; Cordero, Pamos & Seisdedos, 2008). The NEO-FFI comprises 60 items with five response options that range from strongly disagree to strongly agree. This instrument has shown an acceptable internal consistency, with a Cronbach's alpha of between 0.70 and 0.80.

Procedure
The study protocol was approved by the Clinical Research Ethics Committee of our autonomous community (Record No 6/2016). First, we presented the project to the management teams of the collaborating institutions to obtain the authorizations to implement the project. After approval, members of the research team visited all the different locations during in-person activities in order to inform participants about the project. They explained the study aims, answered any questions and requested the participants' signed informed consent. Data were collected by four experimenters in a single session lasting around 60 min. The assessments were conducted in group format at the collaborating institutions, during the normal schedule. 1

Data analysis
Statistical analyses were conducted using IBM SPSS Statistics 24 (SPSS, Inc., Chicago, IL). The criterion for statistical significance was set at p ≤ 0.05. Logical tests and range tests were conducted, as were data consistency tests. After reviewing and cleaning the data, we conducted exploratory analyses and other analyses to categorize and transform the variables. The specific data analysis plan included, first, a descriptive analysis of the main study variables and a t-test for independent samples to determine any possible age-related statistical differences. Second, to examine the association between resilience, personality traits and hopelessness, partial correlation coefficients were estimated, with adjustments made for age. Finally, hierarchical regression models were tested to determine in whole sample the variables that predicted resilience (i.e., age, personality traits, and hopelessness).

Descriptive results
The participants' characteristics are summarized in Table 1. Additionally, independent samples t-tests were used to analyze possible statistical differences between age groups. Overall, the young group presented higher mean values in resilience, neuroticism, extraversion, and openness (p < 0.05), while the older group had higher mean values in hopelessness (p < 0.001). There were no statistically significant differences by age in personality traits, namely, agreeableness and conscientiousness.

Correlation results
After adjusting for age, partial correlation coefficients between personality traits and hopelessness and resilience showed that resilience was significantly related to all the personality traits (Table 2). Positive associations were found for extraversion, openness, agreeableness and conscientiousness, and a negative association was found between resilience and neuroticism. We also found that resilience was negatively and significantly related to hopelessness. In addition, as expected, while most personality traits were negatively associated with hopelessness, neuroticism showed a positive relation.

Hierarchical regression analyses
For the whole study sample (N = 439), the hierarchical regression model was conducted with age, personality traits (i.e., neuroticism, extraversion, openness, agreeableness, and conscientiousness) and hopelessness as predictor variables, and resilience as dependent variable. Age was entered in the regression in Step 1, personality traits were entered in the following steps. In the final step, hopelessness scores were added (Table 3). The results showed the variables that explained resilience were neuroticism, extraversion, openness, and hopelessness. Interestingly, age was initially a predictor for resilience; however, when hopelessness was included in the regression model, age was no longer statistically significant.

DISCUSSION
The main aim of this work was to analyze the association between resilience and personality traits in a sample of Spanish participants. Resilience is currently considered a complex construct made up of constitutional variables and aptitudes that facilitate overcoming life challenges. It is worth highlighting that a resilient personality is characterized by low neuroticism and relatively high levels of the other traits (Bohane, Maguire & Richardson, 2017). After adjusting for age, our results revealed a significant relation between personality traits and resilience levels, which is consistent with the findings of previous studies  Specifically, resilience was negatively related to neuroticism, reinforcing the notion that vulnerability to stress is characteristic of this trait, with individuals scoring high in neuroticism being likely to also present lower resilience levels (Campbell-Sills et al., 2006), which, in turn, might be predictors of mental health problems (McDonnell & Semkovska, 2020;Perna, Riva, Defillo, Sangiorgio, Nobile & Caldirola, 2020). In addition, we found that resilience was directly associated with extraversion, openness, agreeableness, and conscientiousness. Various studies have reported similar findings (Davey, Eaker & Walters, 2016;F€ arber & Rosendahl, 2020;McDonnell & Semkovska, 2020;Oshio et al., 2018), which would underscore the important role of resilience as an effective mechanism for dealing with adversity (Oshio et al., 2018). As regards the role of hopelessness, it has been reported that negative future-oriented thinking has a detrimental impact on resilience (Gooding, Hurst, Johnson & Tarrier, 2012) and has been shown to be a factor predicting lower levels of resilience (Hjemdal et al., 2012). In line with previous findings (Gooding et al., 2012;MacLeod, Musich, Hawkins, Alsgaard & Wicker, 2016), our data show an inverse relation between resilience and hopelessness, with hopelessness being a significant predictor of lower levels of resilience. Additionally, the traits of neuroticism and introversion increase the likelihood of experiencing hopelessness (Hjemdal et al., 2012), a finding which is consistent with our results. Concerning age, the levels of hopelessness found in our study were significantly higher in older adults than in their young counterparts. Age differences in hopelessness may underlie the changes and losses experienced over life, arguably promoting a pessimistic outlook on the future. Aging for example, is a life stage with greater exposure to health problems, disability, death, loneliness, and pain (Harithasan, Mukari, Ishak, Shahar & Yeong, 2020;Meichsner, O'Connor, Skritskaya & Shear, 2020), while young adulthood is considered a period of change in which identity is consolidated and decisions are made related to personal and professional life (Wolf & Zimprich, 2015). It is worth noting, however, that most older people do not experience hopelessness, but when it appears, it differs to that experienced by young adults, since certain elements of the aging process generate uncertainty and negative expectations (see Hernandez & Overholser, 2020, for a review).
As for age differences, these appear not to have been a core focus of studies on resilience, and conclusions in this area thus remain uncertain (Lee et al., 2013). In studies using the CD-RISC, for example, no significant relations have been found between age and levels of resilience, suggesting a more specific role of life experiences (Pulido et al., 2020). However, when other measures have been used, older adults have been shown to be more resilient with respect to emotional regulation and problem solving, while resilience in younger adults is related to social support (Gooding et al., 2012). On the other hand, MacLeod et al. (2016) indicated that higher levels of resilience were associated with increasing age, suggesting that young adults are not always as resilient as older ones. Our results showed that the young adults were more resilient than their older counterparts, although age was not a significant predictor of resilience. It is important to highlight that neuroticism, extraversion, openness, and hopelessness were the variables that explained the levels of resilience. Therefore, the effect of these variables on the levels of resilience seems important in different generations. Consequently, along with the demonstrated relation between resilience and personality traits (Oshio et al., 2018), the role of hopelessness is also highlighted. However, to our understanding, this is a topic that has been insufficiently explored and our approaches could be considered preliminary results, with the purpose of subsequently conducting a more exhaustive study on resilience and hopelessness. It might even be considered a transdiagnostic variable, due to its impact on mental health, because it is a construct that reflects negative evaluations about the future and is also a significant predictor of suicidal behaviors and ideation (e.g., Hernandez & Overholser, 2020;Hirsch, Hall, Wise, Brooks, Chang & Sirois, 2019;Sueki, 2022). The findings from the present work need to be interpreted in light of the following limitations. First, the cross-sectional study nature prevents us from making cause-effect inferences. Longitudinal data would yield more complete information on within-participant development in each of the variables analyzed, considering that the ways in which resilience manifests itself may change for different types of adversity, and resilience can be understood as the result of the experiential learning and adaptation over time (Cosco, Kok, Wister & Howse, 2019;Malhi et al., 2019). Second, regarding the resilience measure, it is necessary to be cautious when generalizing results in this area, because different scales incorporate different constructs, due to the diversity in the operation of resilience (Sarubin et al., 2015). In fact, there are different approaches about resilience being a process or an individual disposition, or both (Leys, Arnal, Wollast, Rolin, Kotsou, & Fossion, 2020). We have used the CD-RISC scale, which conceptualizes resilience as the personal qualities that enable one to thrive in the face of adversity (Connor & Davidson, 2003), even though, we could incorporate different resilience measures in future studies. Likewise, we could also evaluate stress coping strategies that complement the information provided by resilience when comparing age groups (e.g., Nieto, Romero, Ros et al., 2020), following the approaches of the Socioemotional Selectivity Theory (Carstensen, 2006), which proposes the shift of personal goals and behaviors with age. In the same vein, it has also been suggested that age strengthens the ability to distance oneself from stressful situations and reassess them positively (Schryer & Ross, 2012). Finally, regarding the external and cultural validity of the results, our data were collected from a convenience sample in which all participants were Caucasian Spanish adults from a medium-high economic status background.
We consider that future studies should focus on the replication of our findings in samples from different cultures and socioeconomic statuses with different levels of risk exposure. For example, Blessin, Lehmann, Kunzler, van Dick and Lieb (2022) suggest that because the world is increasingly intercultural, we should reassess the way we consider different countries in psychological research, which could help to complete our knowledge about effective resilience approaches and related factors.
To sum up, resilience was related to personality traits and hopelessness. In addition, young adults exhibited higher levels of resilience than older adults. However, age was not a significant predictor of resilience. Importantly, neuroticism, extraversion, openness, and hopelessness explained resilience levels in our study sample. These findings could be interesting to improve mental health interventions, due to the recognized importance of resilience in competently overcoming adverse life circumstances. Additionally, these approaches may also be applicable in the global COVID-19 pandemic situation, as there is great concern about the psychological impacts of the pandemic on mental health. Therefore, enhancing resilience might have positive implications in terms of mental health status (Tseliou & Ashfield-Watt, 2022;Verdolini, Amoretti, Montejo et al., 2021).
