Relationships Between Identity, Well-Being, and Willingness to Sacrifice in Personal and Collective Favorite Places: The Mediating Role of Well-Being

In line with research indicating positive associations between well-being and personal and collective people-place bonding, and that collectivistic compared to individualistic commitment may have stronger associations with pro-environmental behavior, we investigated relationships between identity, well-being, and willingness to sacrifice (type of pro-environmental behavior) in personal and collective favorite places. A total of 884 respondents, living in three Swedish municipalities, participated in this study. In line with the hypotheses, we showed congruent positive relationships between place-related: (1) personal identity and personal well-being; (2) collective identity and collective well-being, (3) collective identity and collective willingness to sacrifice; and (4) an incongruent positive association between collective identity and personal willingness to sacrifice. Additionally, a significant role of well-being in mediating the identity → willingness to sacrifice relationship was reported, suggesting that our willingness to pay higher taxes and prices and to accept cuts in standard of living in order to protect our personal and collective favorite places might be accounted for partly by how we feel visiting these places.


INTRODUCTION
We are not placeless (Casey, 2000). We bond as individuals and collectives to physical sites in our lives (Lewicka, 2008;Knez, 2014). We also feel good when visiting these favorite places (Knez and Eliasson, 2017;Knez et al., 2018b). We miss them when they are gone (Knez et al., 2018a), and we behave pro-environmentally to protect them implying, for example, an instrumental milieurelated value (to care for the good of a site because it satisfies our needs; see, e.g., Dietz et al., 2005 for a review). Given this, the aim of the present study was to investigate relationships between three important place-related phenomena of identity (emotional and cognitive bonds tied to personal and collective favorite places), well-being (feelings of wellness associated with personal and collective favorite places), and willingness to sacrifice (type of pro-environmental behavior ascribed to personal and collective favorite places; that is, pay higher taxes and prices and accept cuts in standard of living to protect favorite places). As far as we know, these relationships have not been addressed by previous research.
People-place bonds include both personal (Knez, 2006;Taylor, 2010) and collective (Lewicka, 2008) emotional and cognitive ties, by which we maintain and strengthen our placerelated identifications (Wang, 2008;Wheeler, 2014). In addition, collective identity relates to "group membership, group processes and intergroup behavior, " while personal identity is associated with "close personal relationships and idiosyncratic attributes" (Hogg, 2006, p. 463). These experiences are apportioned across declarative memory as autobiographical memory; hence, a selfrelated memory (Kihlström and Klein, 1994;Conway, 2005) phenomenologically shared as a life story (Fivush, 2008). The result is a feeling of "re-living the past" (Klein, 2013, p. 3), when we communicate in spoken and written words about our lives and ourselves.
In line with the autobiographical memory approach, Knez (2014; see also Knez, 2016b) proposed a role for emotional and cognitive constituents accounting for the phenomenon of place-related identity, involving cognitive processes of coherence, correspondence, mental temporality (inner "time travel"), reflection, and agency (Conway et al., 2004;Klein et al., 2004), as well as an emotional process of attachment/closeness/belonging (Marris, 1982;Hidalgo and Hernandez, 2001;Knez, 2005; however, see Knez and Eliasson, 2017 for a more elaborated discussion about different place-attachment/identity approaches in environmental psychology). Given this, we think, remember and reason about, and feel closeness to our favorite physical sites. In the words of Knez (2014), p. 186): ". . .places and time position-anchor one's reminiscence by forming psychological person-place ties, emotional and cognitive bonds that conduct the psychological agent toward physical place and time as the organizing formats for its personal memory." The psychological phenomenon of place-related identity also includes information about the surrounding nature (Knez, 2005(Knez, , 2006Knez and Eliasson, 2017;Butler et al., 2019), which has been reported to be associated with: (1) Curative feelings of wellbeing (Korpela, 1989(Korpela, , 1992Korpela and Hartig, 1996;Knez, 2006) for both personal and collective favorite places (Knez and Eliasson, 2017); and (2) Emotional loss of a beloved site after a natural disaster (Knez et al., 2018a;Butler et al., 2019). Thus: "Natural or semi-natural features of the environment are often associated with the identity of an individual, a community, or a society. They provide experiences shared across generations, as well as settings for communal interactions important to cultural ties" (Daniel et al., 2012, p. 8814). Consequently, natural and cultural attributes and features of a physical site are central to the self, identity and memory (Knez, 2005(Knez, , 2006Lowenthal, 2005;Aplin, 2007;Erll, 2011;Butler et al., 2019).

Place-Related Well-Being
For a long time, humans have related to, and bonded with, nature due to its curative and restorative dimensions (Wilson, 1984;Kellert and Wilson, 1993;Gesler, 2000). In many ancient cultures archetypical landscapes, e.g., Garden of Eden, have long been connected with supreme types of life and well-being (Ward Thompson, 2011). Also, in fiction, self-biographical nature-related reflections are portrayed, e.g., "pure Alpine air and magnificent mountain landscapes" (Gesler, 2000, p. 126) and "When I am lonely the mountains call me" (Griffin-Pierce, 1997, p. 1). The scientific investigation of the relationship between humans and the surrounding nature started, we might say, in 1732 when the eminent natural scientist, Carl von Linné suggested, based on his empirical observations, an association between nature and human wellbeing (Linné von and James Edward, 1811).
For the most part, these results have been given emotional, aesthetic, and cognitive explanations (e.g., Ulrich, 1983;Kaplan, 1995), overlooking the importance of identity, memory, and wellbeing links with personal and collective nature-related favorite sites. However, Ratcliffe and Korpela (2016), Knez and Eliasson (2017), and Morton et al. (2017) have recently addressed these issues. Knez and Eliasson (2017) showed, for example, a positive relationship between well-being and nature-related place identity in personal and collective favorite places, implying a mediating role for place-identity in the nature-well-being relationship.
This was recently supported by Knez et al. (2018b) showing that when visiting their favorite high-naturalness places, residents perceived higher levels of well-being. A mediation analysis additionally reported that a naturalness-well-being link was, to a certain degree, accounted for by the placeidentity, especially the emotion component of people-place bonding (Knez et al., 2018b; see also Knez et al., 2018a). This suggests, theoretically, that the self, in a self-regulating way (Korpela, 1989(Korpela, , 1992Korpela and Hartig, 1996;Knez, 2006Knez, , 2014, may promote processes of affect-regulation (Parkinson and Totterdell, 1999;Korpela et al., 2001), meaning that the self will enjoy the greenery of places associated with strong place-identity and by that boost the processes of well-being.
Finally, the relations between nature and place-related self/identity has additionally been measured by, for example, connectedness and connectivity to nature (Mayer and Frantz, 2004;Dutcher et al., 2007), and inclusion of nature into the self (Schultz, 2002). However, as far we know, no studies have investigated the relationships between personal and collective people-place ties and well-being in personal and collective favorite sites respectively.
Willingness to sacrifice, which is addressed in this paper, represents an environment-related behavioral intention. More precisely, a willingness to: (1) Pay higher taxes to protect the environment; (2) Pay higher prices to protect the environment and (3) Accept cuts in standard of living to protect the environment (Oreg and Katz-Gerro, 2006;Knez, 2016a). This phenomenon, in general terms, is associated with strong commitment; for example, in close relationships (Lange van et al., 1997). Previous research has indicated, for example, that people with strong egoistic values will perceive less willingness to sacrifice, and vice versa for those with strong altruistic values (Knez, 2013(Knez, , 2016a. Additionally, Davis et al. (2011) have reported that commitment to natural sites (measured as place attachment) may predict willingness to sacrifice. Furthermore, Iwata (2002) and Chen and Zheng (2016) have indicated positive relationships between environmental responsibility and willingness to sacrifice.
Thus, and in the words of Davis et al. (2011, p. 3): "willingness to sacrifice for the environment represents the extent to which individuals' decisions will take into account the well-being of the environment, even at the expense of immediate self-interest, effort, or costs." In line with this, Brown and Kasser (2005) have shown positive associations between ecologically responsible behavior (type of pro-environmental behavior) and well-being. Several studies have also indicated relationships between commitment and pro-environmental behavioral intentions (Davis et al., 2009), tentatively suggesting that collective vs. personal commitment may operate better in an environmental perspective (Lubell, 2002;Clayton, 2003;Wakefield et al., 2006). In the words of Steg and Vlek (2009): ". . .the more strongly individuals subscribe to values beyond their immediate own interests, that is, self-transcendent, prosocial, altruistic or biospheric values, the more likely they are to engage in pro-environmental behavior." It has been suggested that classical social identity theory (Tajfel, 1978;Tajfel and Turner, 1986) may account for this type of finding. That is, a social identity, a type of social commitment, may encourage individuals to define themselves more as a group of environmentalists than individuals (Brunsting and Postmes, 2002;Opotow and Brook, 2003;Dono et al., 2010). In line with this, we will investigate how the behavioral intention of willingness to sacrifice applies to personal and collective favorite places, as types of commitment (place-identities). Both commitment and identification with a place involve the psychological process of associating the self closely with a place, implying that the self might feel part of the place. For that reason, the phenomenon of supporting and making oneself responsible for a place (commitment) can be measured with people-place bonding instruments (see section "Place Identity" for details).
In addition and following Knez and Eliasson (2017), congruent (personal-personal and collective-collective) compared to incongruent (personal-collective and collective-personal) relationships (hypotheses 1, 2, 3, and 4) were predicted to be stronger. On the other hand, in line with, for example, Clayton (2003) and Dono et al. (2010), findings suggesting an advantage of collective vs. individual commitment in pro-environmental behavior, incongruent (collective-personal) compared to congruent (personal-personal) relationship, hypothesis 5, were predicted to be stronger. Accordingly, we hypothesized: (1) Positive congruent association between personal (vs. collective) identity and personal well-being.
collective) identity and personal willingness to sacrifice. (3) Positive congruent association between collective (vs. personal) identity and collective well-being. (4) Positive congruent association between collective (vs. personal) identity and collective willingness to sacrifice. (5) Incongruent positive association between collective identity and personal willingness to sacrifice. (6) In line with research indicating positive relationships between well-being and pro-environmental behavior (e.g., Brown and Kasser, 2005;Davis et al., 2011), we also predicted that associations between identity and willingness to sacrifice might be mediated, to some extent, by well-being ascribed to personal and collective favorite places.

Study Area
The study area includes the municipalities Mariestad, Götene and Lidköping (1706 km 2 land and 1791 km 2 lake), where Lake Vänern Archipelago Biosphere Reserve is situated (40 • E, 65 • N). The area runs along the southeastern shore of Lake Vänern in the southwestern part of Sweden (see Figure 1). Much of the landscape (42%) is covered by arable land on post-glacial clayey plains, explaining the numerous food industries in this part of Sweden. Along the Vänern shoreline, gneiss ridges break up the plain and, continuing out into the water, form an island-rich archipelago in this, the largest lake in the European Union (Drotz et al., 2014). The climate is slightly maritime due to the large body of water. The average temperature in January is −3 • C and in July 15 • C. Mylonite intrusions, glacial moraine deposits and the Cambro-Silurian hill Kinnekulle, provide variation in the topography and bedrock chemical content; thereby creating varying prerequisites for biodiversity. People have lived in this area for at least 6,000 years (Drotz et al., 2014). An abundance of pre-historical and historical landmarks and artifacts dating back to the Bronze Age also imply millennia of cultivation and influence on the landscape, still visible in the diversity of plant species (Gustavsson et al., 2007).

Sample
A total of 2,989 households, identified from a population register, were sent a "landscape survey." They were randomly and proportionally distributed across three municipalities (Lidköping 51.2%, Mariestad 31.5%, and Götene 17.2%) encompassing the Lake Vänern Archipelago Biosphere Reserve. Participants were not offered any incentive to participate. The survey involved several sections, including qualitative and quantitative questions. Data on place-related values, personal and collective identity, well-being, and willingness to sacrifice are reported in this study. The survey was anonymous and was conducted in accordance with the ethical guidelines of APA and the University of Gothenburg Sweden, which was in charge of the project. Therefore, it was not reviewed and approved by any special ethic committee.

Measures
Valuations and Categorizations of Personal and Collective Favorite Places (Qualitative Data) In line with Knez and Eliasson (2017) we asked: Which three places in the landscape are the most important for you personally? By this we mean places that are your favorites; places which increase your understanding of who you are? Participants were asked to write down the names of these places or mark them on a map included in the survey. They were further asked to select one of the three places -your favorite site-and to write down what they valued most about this place. All this was repeated for the collective favorite places: Which three places in the landscape are the most important for you living in the Lake Vänern Archipelago Biosphere Reserve; that is, sites that enhance understanding of the identity of the Biosphere Reserve? (Note: singular form of "you" in Swedish is "dig, " and plural form is "er"; consequently, connoting directly to personal vs. collective dimensions of "you"). Finally, participants were asked to categorize their personal and collective favorite places as belonging to environmental categories of archipelago, agricultural landscape, forest, built-up environment, or other.

Place Identity
Davis et al. (2011) measured commitment to natural sites with a place attachment instrument. We used a measure of place-identity comprising both an emotional (place-related attachment/closeness/belonging) and a cognitive (place-related coherence, correspondence, mental temporality, reflection, and agency) component of people-place bonding (Knez, 2014;Knez and Eliasson, 2017;Butler et al., 2019). This measure involves autobiographical emotional and cognitive components, comprising 10 statements (Knez and Eliasson, 2017). Emotional component (processes of attachment/closeness/belonging; in the present study, with a Cronbach alpha of 0.90): "I am keenly familiar with the place." (emotional familiarity); "I miss it when I'm not there. (emotional missing)"; "I have strong ties to the place." (emotional bond); "I am proud of the place." (emotional pride); "The place is a part of me." (emotional agency). Cognitive component (processes of coherence, correspondence, mental temporality, reflection and agency; in the present study, with a Cronbach alpha of 0.93): "I have had a personal contact with this place over a long period." (coherence); "There is a link between the place and my current life." (correspondence); "I can travel back and forth in time mentally to this place when I think about it." (mental temporality); "I can reflect on the memories attached to this place." (reflection); "These thoughts about the place are part of me." (cognitive agency). Participants were asked to respond to these statements on a seven-point scale, ranging from 1 (completely disagree) to 7 (completely agree). For the collective place identity measure, we changed the pronoun "I" to "we (living in the XX)."

Well-Being
Participants were asked to respond to 10 statements from "The WHO (ten) well-being index" (Beach et al., 1996), measuring their place-related well-being. They responded to the question, when I'm on the site, I feel: "Sad and down" (R); "Calm and relaxed"; "Energetic, active and enterprising"; "Relaxed and refreshed"; "Happy and pleased with my personal life"; "Satisfied with my living situation"; "I live the life I want to live"; "Inspired to deal with today's work"; "I can cope with serious problems or changes in my life"; "That life is full of interesting things." Furthermore, the four-point scale from the original measure was rearranged yielding a seven-point scale, ranging from 1 (completely disagree) to 7 (completely agree), with a Cronbach alpha of 0.90.

Willingness to Sacrifice
This measure involved three items (Oreg and Katz-Gerro, 2006;Knez, 2016a): "I am willing to pay higher taxes to protect the environment."; "I am willing to pay higher prices to protect the environment."; and "I am willing to accept cuts in standard of living to protect the environment." with Cronbach alpha of 0.91. Participants were asked to respond to these statements on a seven-point scale ranging from 1 (completely disagree) to 7 (completely agree).

Design and Analyses
Hypotheses 1-5 were estimated with multiple regression analyses, including the two types of place identity as predictors, and wellbeing/willingness to sacrifice as criterion variable. Hypothesis 6, that is, the mediating role of well-being in identity → willingness to sacrifice link was investigated by performing two mediation analyses, one for each type of identity; using the plugin PROCESS (Hayes, 2013) developed for IBM SPSS Statistics.

RESULTS
We first report qualitative results involving the valuations and categorizations of personal and collective favorite places, and second, quantitative results including (1) regression analyses related to the 1-5 hypotheses, and (2) mediation analyses related to the question about the mediation role of well-being in the links between identity and willingness to sacrifice (Hypothesis 6).

Regression Analyses
As can be seen in Table 1, a significant relationship between personal and collective identity and personal well-being showed that psychological mechanisms of people-place bonding accounted for 33% of variance in well-being. However, and in line with Hypothesis 1, the link between personal identity and personal well-being was stronger than between collective identity and personal well-being (see β statistics in Table 1, 0.40 vs. 0.24, indicating the slope of the regression lines). Thus, the better the personal/collective congruency between the phenomena of identity and well-being the higher well-being will be perceived at the favorite place. Similar to the above, it was shown that psychological mechanisms of people-place bonding accounted for 27% of variance in well-being (see Table 2). However, and in line with Hypothesis 2, the link between personal identity and collective well-being was weaker than between collective identity and collective well-being (β statistics 0.21 vs. 037. This mirrors and replicates the above results suggesting that people perceive highest place-related well-being when the phenomena of placerelated identity and well-being match (compare Tables 1, 2).
In line with Hypotheses 2 and 4, significant relationships between personal and collective identity and personal willingness to sacrifice showed that psychological mechanisms of peopleplace bonding accounted for 16% of variance in willingness to sacrifice (see Table 3). However, and in line with Hypothesis 5, the link between personal identity and personal willingness to sacrifice well-being was slightly weaker than between collective identity and personal willingness to sacrifice ( Table 3, β statistics 0.19 vs. 026. As predicted, this indicates an advantage of collective over individual commitment (measured as place-bonding) in willingness to sacrifice.  Additionally, as can be seen in Table 4, the link between personal identity and collective willingness to sacrifice was much weaker than between collective identity and personal willingness to sacrifice (β statistics 0.09 vs. 0.37). This underlines that the above obtained results suggest an advantage of collective vs. individual commitment (measured as place-bonding) in willingness to sacrifice, both personal and collective.

Mediation Analyses
As proposed by Hypothesis 6, a mediation analysis, PROCESS, developed by Andrew F. Hayes (Hayes, 2013) for IBM SPSS was performed. As can be seen in Figure 2, the results showed that: (1) personal identity predicts personal well-being (b = 0.37, p < 0.001); (2) personal well-being predicts personal willingness to sacrifice (b = 0.41, p < 0.001); and (3) personal identity predicts personal willingness to sacrifice (b = 0.28, p < 0.001). It was also reported that personal identity as predictor of personal willingness to sacrifice ("direct effect") was mediated ("indirect effect") by personal well-being (b = 0.15, CI 0.10-0.20, SE = 0.03, z = 5.76, p < 0.001). The mediation test was performed by computing confidence intervals for the "indirect" effect using bootstrap methods. Concerning the effect size, all (un)standardized confidence intervals contained no-zero point estimates; thus, "we can be confident that the true effects' size is different from no effect" (Field, 2013, p. 416).

DISCUSSION
This study investigated relationships between place-related phenomena of identity, well-being and pro-environmental behavior (willingness to sacrifice) related to personal and collective favorite places of residents living in three Swedish municipalities, where the Lake Vänern Archipelago Biosphere Reserve is located (see Figure 1). We predicted that four of five positive associations would be stronger when they appeared congruently, and that one incongruent relationship would be stronger than the comparable congruent one (Hypotheses 1-5). Additionally, we predicted that the positive link between identity and willingness to sacrifice would be mediated by wellbeing (Hypothesis 6).
According to the qualitative data results, residents' personal and collective favorite places were mostly categorized as naturerelated sites (archipelago, forest, and agricultural landscape). Collective favorite places included, however, also the category of built-up environment. The most valued attributes ascribed to both types of places were related to nature, nature-related esthetics, tranquility, and social activities. This is in line with previous research suggesting that people are active in visiting and using favorite, nature-related places for emotional self-regulation, aesthetic, and social values (e.g., Korpela, 1989;Korpela and Hartig, 1996;Hammitt et al., 2006;Knez, 2006;Brown and Raymond, 2007;Knez and Eliasson, 2017;Knez et al., 2018b).
In line with previous findings (e.g., Knez and Eliasson, 2017;Knez et al., 2018a,b), a positive relationship between identity and well-being was reported, indicating that the stronger identity participants ascribed to a place the more well-being they felt visiting that site. As hypothesized, this association was shown to be stronger in congruent, compared to incongruent, relationships of: (1) personal identity and personal well-being related to a personal favorite place; and (2) collective identity and collective well-being related to a collective favorite place. This is consonant with previous studies showing that nature-related engagement and bonding may generate health-related benefits (Pretty, 2004;Pretty et al., 2005) of healthy-nature-healthy-people links (Maller et al., 2005;Carrus et al., 2015;Knez et al., 2018b). However, as far as we know, no previous research has indicated the importance of personal/collective congruence in nature-related bonding and well-being relationships.
Consonant, in general terms, with Davis et al. (2011;see also Iwata, 2002;Chen and Zheng, 2016), findings of a positive relationship between commitment (measured with a place identity instrument involving both emotional -attachmentand cognitive dimensions) to nature-related places and proenvironmental behavior of willingness to sacrifice, we reported that collective compared to personal place-identity predicts a stronger relationship with willingness to sacrifice to both personal and collective favorite places. In accordance with social identity theory (Tajfel, 1978;Tajfel and Turner, 1986), and previous research tentatively indicating an advantage of collective over individual commitment (e.g., Brunsting and Postmes, 2002;Clayton, 2003;Opotow and Brook, 2003;Dono et al., 2010), this suggests that a group compared to an individual is more willing to pay higher taxes and prices, as well as accept cuts in the standard of living, in order to maintain both types of favorite places; however, mostly for the sake of collective favorite sites.
Finally, and in accordance with, for example, the findings of Brown and Kasser (2005) and Davis et al. (2011), the mediation analyses showed that the relationships between personal and collective identity and willingness to sacrifice was partly accounted for by well-being, in both types of place. This suggests that a curative effect of revisiting and staying in a personal/collective favorite place (Knez and Eliasson, 2017;Knez et al., 2018b) may significantly influence the pro-environmental behavior of willingness to sacrifice. People will, in other words, maintain and preserve (pro-environmental behavior) beloved sites, not only because they like them and think about them (place-identity), but also because they feel good (well-being) staying in and revisiting these places.

CONCLUSION
Overall, our results suggest that: (1) The more we identify ourselves emotionally and cognitively with a place the more we will experience, in congruence with personal/collective bonding, well-being in that favorite place (In other words, I feel best visiting my favorite places, and I, as an individual belonging to a group, feel best visiting our favorite places); (2) Additionally, the curative feelings ascribed to a favorite place will make us more pro-environmental toward that place; that is, in order to maintain and preserve the beloved site, we will be more willing to pay higher taxes and prices, and accept cuts in our standard of living; (3) Pro-environmental behavior, however, is more related to us as a collective than as an individual, and more to our collective than personal favorite sites.
