Stability and change of basic personal values in early adolescence: A 2‐year longitudinal study

Raising to conformity without strictness: is it achievable?

Background

The prevailing belief that parental strictness is optimal for children is not uniformly supported by recent research. Contrary to the traditional notion that strictness is necessary to ensure children's conformity to social norms, contemporary studies question its necessity. This study aims to analyze how two main parenting dimensions, warmth and strictness, are related to the psychosocial adjustment of children.

Method

A sample of 1,224 Spanish adolescents and young adults was examined, divided into two groups: adolescents aged 12-18 years (51.14%) and young adults aged 19-35 years (48.86%). Adolescent participants were recruited from high schools while young adults were recruited from university courses. Children (i.e., adolescent and young adult offspring) responded to an online questionnaire that included all measures: parenting dimensions (warmth and strictness) and children's psychosocial adjustment criteria (emotional self-concept, self-esteem, social competence, and conformity). Power analyses (a priori and sensitivity analyses) were applied to ensure sufficient sample sizes to achieve adequate power. Cohen's d values from correlation analyses and multiple linear regression analyses were performed. Beta confidence intervals were analyzed to relate parenting dimensions, sex and age to self-concept, self-esteem, social competence, and conformity.

Results

The statistical analysis plainly indicated that parental warmth was positively associated with criteria for child psychosocial adjustment, including self-esteem, social competence, and conformity. This relationship was consistent across both adolescents and young adults. Conversely, parental strictness was either negatively related to or not significantly associated with these criteria.

Conclusion

This study clearly suggests that, completely contrary to expectations that strict parenting might be a need component to achieving psychosocial adjustment, parental warmth, rather than strictness, is more effective in promoting children's psychosocial adjustment.

Psilocybin-Assisted Therapy May Enhance Conservation Values in Patients with Alcohol Use Disorder

Background

Psilocybin can produce long-term changes in personality, personal values, and behavior. Although psilocybin-assisted therapy (PAT) is being actively studied for various psychiatric conditions, its effects on personal values in patients with alcohol use disorder (AUD) remain unexplored. This study examined the effects of PAT on personal values in patients with AUD and assessed relationships between value changes, acute psilocybin experiences, and drinking outcomes.

Methods

In a phase II clinical trial (NCT02061293), 93 participants with AUD received 12 weeks of treatment, including manualized psychotherapy and two 8-h drug administration sessions with either psilocybin (n = 48) or active placebo (n = 45). Personal values were assessed before and after treatment using the Schwartz Value Survey (SVS), which includes 4 domain scores (Openness to Change, Self-Enhancement, Conservation, Self-Transcendence) and 10 subscales. The acute psychedelic experience was measured using the 30-item Mystical Experience Questionnaire (MEQ) and the 5-Dimensional Altered States of Consciousness Scale (5D-ASC). Treatment effects were assessed using univariate ANCOVAs, with baseline SVS values as covariates. Time effects within each group were evaluated using paired t-tests. Pearson correlations examined the relationship between value changes and acute effects, and also value changes and drinking outcomes.

Results

Significant treatment effects were detected for the Conservation domain and its subscales "security" and "tradition." No other domains or subscales showed significant treatment effects. Within the psilocybin group, time effects were significant only for conservation, and its subscales "tradition," and "security". No significant time effects were detected in the placebo group. In the psilocybin group, the MEQ subscale Ineffability was significantly associated with increases in Conservation, "security," and "tradition" (r = 0.31-0.34). 5D-ASC subscale Vigilance Reduction was associated with Conservation (r = 0.31), but not its subscales. 5D-ASC subscale Dread of Ego Dissolution during the psilocybin sessions correlated with increases in "tradition" (r = 0.31). None of the value changes were significantly associated with drinking outcomes.

Conclusion

PAT may alter value structure in patients with AUD patients by increasing Conservation. Although some associations were found between acute psychedelic effects and changes in Conservation, these value changes were not related to drinking outcomes.

Investigating the Consumer Choices of Gen Z: A Sustainable Food System Perspective

Background/Objectives: Developing nutrition-oriented and more responsible consumer behaviors is crucial for the well-being of current and future generations. Food choice determinants and concerns of Gen Zs-also referred to as Post-Millennials, or Zoomers-were explored from a sustainable food system perspective to identify factors encouraging young people to be on the front line of this much-needed transformation. Methods: Quantitative data were collected with the use of the CAWI method from 650 adults representing Generation Z living in Polish cities. Statistical analysis identified three consumer segments, and cluster (CL) means were statistically contrasted using a one-way ANOVA with Scheffé tests for post hoc comparisons. Results: The research results indicate that the key considerations of food choice in the studied Gen Z sample are taste, price, and health. External factors, such as social media influencers and consumer trends, play a relatively minor role in decision-making. Gen Zs were more aware of the link between their eating patterns and health than the link between their eating habits and the natural environment. Members of the biggest cluster (CL3), constituting 48.3% of the total sample, declared the highest level of agreement with statements referring to links between diet, environment, and health from the food system perspective. This most allo-centered (community-oriented, altruistic) consumer segment, differing significantly with gender to other CLs was more concerned about climate change and protecting the natural environment and open to changing its dietary habits. Conclusions: Implementing research-based policy measures focusing on Generation Z, especially young women, as potential leaders and drivers of food system change is recommended.

Human Values Across the Lifespan: Age-Graded Differences at Three Hierarchical Levels and What We Can Learn From Them

Personality-development research is flourishing. Here, we extend these efforts horizontally (new constructs) and vertically (new levels within the same construct) by charting out age-graded differences in Schwarz's human values across 80,814 individuals. Conducting a systematic investigation of cross-sectional age-graded differences in human values-from late teenage years to post-retirement-featuring 36 analytical model choices and 180,000 simulation-based decisions, our analyses replicate some earlier findings (e.g., increasing self- and growth-focus during adolescence and increasing security concerns during adulthood), while also highlighting complex and previously unappreciated dynamics. As such, while it is a common practice to aggregate specific values into parsimonious higher-order concepts to ease interpretation, this may risk overlooking meaningful trends in lower-order value development. Specifically, revealing unique and asynchronous patterns for value nuances, we find that aggregation (a) leads to a loss of critical information, (b) creates conflicting results when nuances diverge, and (c) significantly reduces predictive power.

Latent change scores models for applied research: A practical guide using Mplus

The present article provides a practical guide for modelling and interpreting several basic applications of the latent change scores (LCS) model, a useful and flexible approach for the analysis of change. The article is addressed to students, researchers and practitioners who are familiar with structural equation modelling but new to LCS. We first provided a gentle introduction to the LCS model using non-technical language and minimal mathematical formalism. We illustrated the basic ideas behind this approach, introducing LCS in its simplest form. We show how this model can be straightforwardly extended to more complex applications, including the dual change score (DCS) model and some of its variants (i.e., the proportional change and the constant change models). We illustrated how the univariate LCS model can be used to determine the growth trajectory of a variable across multiple waves of assessment. Next, we focused on the bivariate case, which allows for the modelling of the dynamic relations between two variables. For each model, we provided easy-to-follow examples of applications based on Schwartz's theory of basic personal values. The examples are accompanied by annotated syntax and output showing how they can be implemented with the Mplus software and how results can be interpreted.

Age and gender differences in the value development of Dutch adults in 11 years of longitudinal data

Value development over the life-span is rarely studied due to theory and data limitations. We use the LISS data, a Dutch longitudinal dataset, to study value change in adults aged 25-70 over 11 years from 2008 to 2019 (N=10,860), using the neo- socioanalyitcal model (NSM) as a theoretical framework. We find few cohort differences, differences between age groups and non-linear value change within individuals that continues until late adulthood. Gender differences in mean-levels are stable except in universalism and self-direction, while gender differences in rates of change are observed. We conclude that the NSM provides a fruitful framework to interpret value change as a maturation process toward becoming functioning members of society along gendered and age-graded normative stages.

A Fundamental Difference in the Nature of Personal Values and Personality Traits Revealed Through Different Patterns of Stability Across Their Distributions

OBJECTIVE

Personal values and personality traits are both important aspects of personality, but much is still unknown about the fundamental differences between the constructs, including how their patterns of temporal stability compare. This paper investigated patterns of intra-individual stability in both values and traits.

METHOD

Quantile correlations were estimated between each of the 20 refined personal values and the same values 2 years later in a large longitudinal sample of Australian adults (N = 2875). The same was done for each of the 15 Five-Factor Model trait facets in a subsample of these participants (n = 2424).

RESULTS

It was observed that more important values tended to remain more stable over time, while traits retained a similar stability regardless of trait strength, and frequently showed small decreases in stability at extreme levels.

CONCLUSIONS

Findings indicate that highly prioritized values may be a more central aspect of the self, and a more reliable element for predicting future outcomes, than less highly prioritized values, but in contrast, traits do not function in a way that is dependent on trait strength.

Middle childhood development in personal values

OBJECTIVE

We aimed to investigate value change and stability longitudinally in middle childhood.

BACKGROUND

Values are the aspect of personality defining one's aspirations. Research identifies meaningful values in middle childhood, yet we know little about the process of their development within individual.

METHOD

Children (N = 298; 53.7% girls, Mage = 7 years and 3 months, SD = 7.70 months, at the first time point) four times, annually.

RESULTS

Rank-order stability increased with age and decreased with time-span. We found value hierarchy consistency, with value hierarchy similar to adolescents in the priority given to openness to change versus conservation values, and to adults in the priority given to self-transcendence values. Latent growth curve analyses indicated linear increase in openness to change, and curvilinear increase in self-transcendence values, and linear decrease in conservation and self-enhancement values, with some differences across ages. Value structure was better differentiated with age. Compatible values changed in similar, and conflicting values in opposite directions.

CONCLUSIONS

This paper suggests that in middle childhood, children can already report stable values. Moreover, middle childhood is characterized by coherent change patterns, of increase in the importance of growth, and decrease in the focus on conflicting protection values.

Stick to your role! Stability of personal values expressed in large language models

The standard way to study Large Language Models (LLMs) through benchmarks or psychology questionnaires is to provide many different queries from similar minimal contexts (e.g. multiple choice questions). However, due to LLM's highly context-dependent nature, conclusions from such minimal-context evaluations may be little informative about the model's behavior in deployment (where it will be exposed to many new contexts). We argue that context-dependence should be studied as another dimension of LLM comparison alongside others such as cognitive abilities, knowledge, or model size. In this paper, we present a case-study about the stability of value expression over different contexts (simulated conversations on different topics), and as measured using a standard psychology questionnaire (PVQ) and behavioral downstream tasks. We consider 21 LLMs from six families. Reusing methods from psychology, we study Rank-order stability on the population (interpersonal) level, and Ipsative stability on the individual (intrapersonal) level. We explore two settings: with and without instructing LLMs to simulate particular personalities. We observe similar trends in the stability of models and model families-Mixtral, Mistral, GPT-3.5 and Qwen families being more stable than LLaMa-2 and Phi-over those two settings, two different simulated populations, and even on three downstream behavioral tasks. When instructed to simulate particular personas, LLMs exhibit low Rank-Order stability, and this stability further diminishes with conversation length. This highlights the need for future research directions on LLMs that can coherently simulate a diversity of personas, as well as how context-dependence can be studied in more thorough and efficient ways. This paper provides a foundational step in that direction, and, to our knowledge, it is the first study of value stability in LLMs. The project website with code is available at https://sites.google.com/view/llmvaluestability.

Cultural values, parenting and child adjustment in Italy

The present study examined the association of mothers' and fathers' individualism, collectivism and conformity values with parenting behaviours and child adjustment during middle childhood in an Italian sample. Children (n = 194; 95 from Naples and 99 from Rome; 49% girls) were 10.93 years old (SD = .61) at the time of data collection. Their mothers (n = 194) and fathers (n = 152) also participated. Mother and father reports were collected about parental individualism and collectivism, conformity values, warmth, family obligations expectations and their children's internalising and externalising problems. Child reports were collected about their parents' warmth, psychological control, rules/limit-setting, family obligations expectations and their own internalising and externalising behaviours. Multiple regressions predicted each of the parenting and child adjustment variables from the value variables, controlling for child gender and parent education. Results showed that maternal collectivism was associated with high psychological control, parental collectivism was associated with high expectations regarding children's family obligations and fathers' conformity values were associated with more child internalising behaviours. Overall, the present study shed light on how parents' cultural values are related to some parenting practices and children's internalising problems in Italy.

Are values stable throughout adulthood? Evidence from two German long-term panel studies

Previous studies have used cross-sectional or short-term longitudinal data, resulting in a truncated view of a phenomenon unfolding across the lifespan. We find that, contrary to the consensus in the literature, people's values continue developing in adulthood, albeit at a slower pace than in previous developmental stages. We use longitudinal data sources with two measurement instruments. We show their comparability using confirmatory MDS in Study 1 (N = 1,027). We examined value development using latent growth models in a convenience sample of highly educated German peace activists (Study 2, N = 1,209) and corroborated these with evidence from a representative sample from the German population (Study 3, N = 19,566). We find that all values change up to age 40 consistent with theoretical expectations. We observe that with age, self-transcendence and conservation values increase while self-enhancement values decrease. At the same time, we find a curvilinear pattern for openness to change in Study 2 and an overall decrease in Study 3. Moreover, the developmental trajectory of conservation and of self-enhancement in the German general population differ between those with tertiary and without tertiary education. We discuss the implication of the present findings for research on value development and for interventions.

Variability and change in adolescents' prosocial behavior across multiple time scales

We examined variability and change in adolescents' prosocial behaviors directed to peers and friends across four time scales: two-years, one-year, two-monthly, and daily. Data from three longitudinal datasets with a total of 569 adolescents (55.7% girl, M_age  = 15.23, SD = 3.90) were included. The overall time-related stability of prosocial behavior across time scales was moderate to excellent. Variability did not differ between early (age 10-15) and late (age 16-21) adolescence, but late adolescence was associated with higher mean levels of prosociality. Finally, results indicated that prosocial behaviors measured over longer periods (i.e., two-years and one-year) were positively associated with cognitive processes (perspective taking), whereas prosocial behaviors measured over shorter periods (i.e., two-monthly) were positively associated with affective processes (empathy).

How personal values follow the societal lockdown due to COVID-19: Case of business students in Slovenia

We examined patterns of change and stability in four individual-level higher-order groups of Schwartz personal values among individuals during societal lockdown caused by COVID-19 epidemic. The study involves comparison of personal values of 85 business students during societal lockdown, with their personal values in pre- and post-pandemic periods. Sampled group of individuals includes undergraduate and graduate students from University of Maribor, Faculty of Economics and Business, Maribor, Slovenia. Contrary to previous publications, our results indicate a decrease of mean-level for all four higher-order groups of individuals' values during societal lockdown of COVID-19. In the value hierarchy, self-transcendence values remain first, followed by conservation, openness to change, and self-enhancement values. In the period after the COVID-19, personal values again approached their pre-pandemic levels. Self-transcendence and conservation returned close to baseline levels, while openness to change and self-enhancement values exceeded initial pre-epidemic levels. In the value hierarchy, lead openness to change values, followed by the self-transcendence, self-enhancement, and conservation values. We discuss perceived changes in business students' values due to the COVID-19 pandemic and present their capacities for dealing with potential unfavorable and threatening circumstances in the future.

Development of intraindividual value structures in middle childhood: A multicultural and longitudinal investigation

OBJECTIVE

We examined changes in value interrelations during middle childhood. In line with the Personal Values Theory, we expected a value system, with individuals similarly valuing related motivations, and setting priorities between conflicting motivations. We hypothesized this system to develop dynamically during middle childhood as children deepen their understanding of their own values.

METHOD

Using unfolding analysis, we estimated intraindividual value structure coherence, that is, the extent to which the interrelations among a child's values are similar to the hypothesized interrelations. Cross-Cultural Study 1 (N = 4615, 6-12-year-old children) included children from 12 countries. Cross-Sequential Study 2 (N = 629, 6-10-year-old children at Time 1) included three annual measurements.

RESULTS

In Study 1, we found a curvilinear association between age and intraindividual value structure coherence: Children's values were more coherent at ages 9-10 than before or after. Study 2 confirmed this pattern of within-individual development.

CONCLUSIONS

We propose that development in coherence with the theoretical value structure offers insight into children's understanding of values as well as changes in value priorities.

The pre-political origins and policy consequences of environmental justice concern

While the effects of climate change will impact most Americans, they will likely have a disproportionate influence on the socioeconomic well-being of marginalized communities. Few researchers, however, have investigated public support for policies aimed at ameliorating climate-related disparities. Fewer still have considered how political and (critically) pre-political psychological dispositions might shape environmental justice concern (EJC) and subsequently influence policy support-both of which, I argue, could present roadblocks for effective climate communication and policy action. In this registered report, I (1) propose and validate a new measure of EJC, (2) explore its political correlates and pre-political antecedents, and (3) test for a link between EJC and policy support. In addition to psychometrically validating the EJC scale, I find that pre-political value orientations are associated with EJC, which, in turn, mediates the effects of pre-political values on taking action to mitigate the unequal effects of climate change.

Perceived significant others' values: Are they important in the relationship between personal values and self-reported prosociality?

BACKGROUND

Personal values have been extensively found to be relevant variables linked to prosociality; they are desirable and trans-situational goals that serve as guiding principles in people's lives to select modes, means and actions, these reflecting what people consider relevant and worthy. Research has investigated how cultural background influences people's personal values and prosociality, but little is known about the influence of the perception of the values endorsed by significant others, namely the people belonging to the micro-relational context with whom daily interactions and exchanges are possible. Based on Schwartz's theory of basic human values, we analyzed the moderating role of the perceptions of significant others' values in the relationship between personal values and self-reported prosociality.

PARTICIPANTS AND PROCEDURE

Two hundred and forty-five Italian young adults (66.9% women) aged between 18 and 30 years (M = 22.58, SD = 2.53) completed a self-report questionnaire.

RESULTS

Specifically, openness to change values were a significant positive predictor of self-reported prosociality when respondents perceived low importance assigned both to openness to change and self-transcendence by significant others, whereas conservation values were a significant positive predictor of self-reported prosociality when respondents perceived low importance assigned to self-enhancement by significant others.

CONCLUSIONS

Our findings show a complex interplay between personal values and perceived significant others' values in shaping young adults' self-reported prosociality.

Individual and generational value change in an adult population, a 12-year longitudinal panel study

A long-standing conundrum is whether age differences in personality are due to generation, or internal change with age. Using a representative sample from The Netherlands (N = 1599; aged 16-84 at the start), the current research focuses on human values (an important aspect of personality), following the same individuals for 12 years. We distinguish four generations, Silent-generation, Baby-boomers, Generation-X and Millennials. We found clear differences across generations in human values, with Millennials, e.g., valuing hedonism more than all other generations. Furthermore, value change over time was mainly evident in Millennials. Some values (achievement and conformity) were stable within individuals and between generations. Change over time across most values occurred mainly in Millennials, but not for all values. Some values were stable in adults (e.g., hedonism, conformity) while other values still increased (e.g., security, self-direction) or decreased (e.g., power, stimulation) in importance. In adults older than Millennials change decreased and change was absent in the oldest generation. Hence, age differences in values seem both due to generation, as well as internal change, although the latter mainly in young adults. These value changes over time may have implications for developments in societal values in the long run.

Changing Personal Values through Value-Manipulation Tasks: A Systematic Literature Review Based on Schwartz's Theory of Basic Human Values

According to the Theory of Basic Human Values, values are relatively stable, but not immutable, abstract goals which strongly influence peoples’ lives. Since their relative stability, psychosocial research is attempting to understand the extent to which it is possible to induce a voluntary change in people’s personal values. The main aim of this study was to systematically review the existing literature on experiments to induce a value change, also highlighting the theoretical perspectives used to develop the experimental tasks. We conducted a literature search of five databases (SCOPUS, ProQuest, PsycINFO, PubMed, and Web of Science). After the screening and the eligibility phase, we included a total of 14 articles (25 experiments). Most of these studies involved university students and adopted a pre-and post-test design, using different manipulation tasks. The results highlighted the possibility of inducing a voluntary value change, assessed in terms of mean levels and/or rank order. These findings provide new insights regarding the stability of values in the light of the Theory of Basic Human Values. The practical implications and future research directions are discussed.

Between Collectivism and Individualism - Analysis of Changes in Value Systems of Students in the Period of 15 Years

INTRODUCTION

The publication deals with the description of selected aspect of young people's mentality, ie their systems of values. The research was conducted four times: in 2003 (325 respondents), in 2008 (379 respondents), in 2013 (368 respondents), and in 2018 (371 respondents) on students of the Bialystok universities. An attempt was made to establish if in the period of the fifteen years between the first survey and the last surveys one could observe changes in the mentality in the desired direction - from the point of view of political transformations - from "collectivism" to "individualism". The way of understanding values was adopted from Rokeach's theory.

METHODS

The Rokeach Value Survey was used to study the system of values.

RESULTS

The comparative analysis of the value preferences indices across all surveys (survey by survey) has not confirmed proposed hypothesis. It has been shown that the value system has changed towards individualism over fifteen years (when comparing surveys from year 2003 and 2018). Contradictory to the expectations, the most individualistic system of values was presented in survey group in 2008, and not in 2018.

CONCLUSION

There was no increase in rates of preference for individualistic values "from study to study". The trajectories of changes in value systems turned out to be much more complex (and thus more difficult to describe).

Parental Attitudes and the Attitude to Energy Saving among Young People with ASD

The aim of the study was to determine the association between parental attitudes and saving energy in the perception of young people with autism spectrum (13–17 years old). The character of studies was pilot. The diagnostic survey method was used, along with The Scale of Parental Attitudes by M. Plopa and an authored survey questionnaire. Deliberate random sampling was applied. Statistical analysis showed that an attitude towards autonomy manifested by mothers, as well as an attitude of acceptance in mothers and fathers, turned out to be significant in adolescents with ASD showing a positive attitude towards energy saving, and these correlations were positive, strong and statistically significant. An overly protective attitude of mothers turned out to be significant in shaping a negative attitude towards energy saving among adolescents with ASD with a significant, positive moderate correlation. Regression analysis showed that the perception of the father’s parental attitude as accepting was a statistically significant predictor of a positive attitude towards energy saving, and that the perception of the mother’s parental attitude as demanding and overly protective was a statistically significant predictor of a negative attitude to energy saving. The achieved results acquire an additional aspect, i.e., a financial dimension in the household budget.

Longitudinal Links Between Self-Esteem and the Importance of Self-Direction Values During Adolescence

Self-direction values (e.g., independence, curiosity) are among the most important values to people worldwide. However, it is not clear what encourages their development. We propose that self-esteem may be associated with the development of self-direction values because feelings of self-worth provide the confidence needed for independent pursuit. As both independence and self-esteem develop during adolescence, we examined longitudinal associations between self-direction values and self-esteem in adolescents. Study 1 ( NT1 = 527, 55.6% girls, Mage = 16.24, SD = .71, NT2 = 198) included two annual waves of data collection. Study 2 ( Noverall = 486, 55.6% girls, initial Mage = 13.76, SD = .51, NT1 = 418, NT2 = 420, NT3 = 426, NT4 = 387) included four annual waves. In the studies, a cross-lagged panel model and a random-intercept cross-lagged panel model showed that adolescents who feel worthy are more likely to experience an increase in the importance of values of independent thoughts and actions relative to other values. Partial support was found for the opposite direction of association. The results were replicated across longitudinal studies of varying duration and across measures. We discuss the results in light of theories of self-esteem, values, and specifically the development of self-direction values.

Changes in Personal Values in Pandemic Times

The COVID-19 pandemic has had immense impact on people’s lives, potentially leading individuals to reevaluate what they prioritize in life (i.e., their values). We report longitudinal data from Australians 3 years prior to the pandemic, at pandemic onset (April 2020, N = 2,321), and in November–December 2020 ( n = 1,442). While all higher order values were stable prior to the pandemic, conservation values, emphasizing order and stability, became more important during the pandemic. In contrast, openness to change values, emphasizing self-direction and stimulation, showed a decrease during the pandemic, which was reversed in late 2020. Self-transcendence values, emphasizing care for close others, society, and nature, decreased by late 2020. These changes were amplified among individuals worrying about the pandemic. The results support psychological theory of values as usually stable, but also an adaptive system that responds to significant changes in environmental conditions. They also test a new mechanism for value change, worry.

Genetic Correlates of Psychological Responses to the COVID-19 Crisis in Young Adult Twins in Great Britain

We investigated how the COVID-19 crisis and the extraordinary experience of lockdown affected young adults in England and Wales psychologically. One month after lockdown commenced (T2), we assessed 30 psychological and behavioural traits in more than 4000 twins in their mid-twenties and compared their responses to the same traits assessed in 2018 (T1). Mean changes from T1 to T2 were modest and inconsistent. Contrary to the hypothesis that major environmental changes related to COVID-19 would result in increased variance in psychological and behavioural traits, we found that the magnitude of individual differences did not change from T1 to T2. Twin analyses revealed that while genetic factors accounted for about half of the reliable variance at T1 and T2, they only accounted for ~ 15% of individual differences in change from T1 to T2, and that nonshared environmental factors played a major role in psychological and behavioural changes. Shared environmental influences had negligible impact on T1, T2 or T2 change. Genetic factors correlated on average .86 between T1 and T2 and accounted for over half of the phenotypic stability, as would be expected for a 2-year interval even without the major disruption of lockdown. We conclude that the first month of lockdown has not resulted in major psychological or attitudinal shifts in young adults, nor in major changes in the genetic and environmental origins of these traits. Genetic influences on the modest psychological and behavioural changes are likely to be the result of gene-environment correlation not interaction.

The values of religious nones, dones, and sacralized Americans: Links between changes in religious affiliation and Schwartz values

OBJECTIVE

Religious identification is associated with specific values, particularly conservation values that focus on social rather than personal interest. Recent research, however, suggests that the psychological repercussions of religious commitment can persist after people cease identifying as religious. We examine if this religion residue effect leads to differences in values between those who were once religious but no longer identify as religious and those who never identified as religious.

METHODS

We use longitudinal survey data to examine how changes in identification with religion are associated with Schwartz's circle of values.

RESULTS

Results show that religious affiliates were more likely than both those who disaffiliated across waves and those who consistently had no affiliation to endorse each of the social focus values except universalism. As hypothesized, when it came to conservation values, those who disaffiliated from religion were more similar to affiliates than were those who were consistently unaffiliated. Additional analyses showed that (a) associations between religious identification trajectories and values were largely consistent across genders, and (b) those who disaffiliated from evangelical Protestant denominations stood out from other disaffiliates.

CONCLUSIONS

We conclude with a discussion of how these findings further understanding of the association between religion and personal values.

Sustainability in Youth: Environmental Considerations in Adolescence and Their Relationship to Pro-environmental Behavior

Adolescents today face the negative outcomes of climate change, and their pro-environmental behavior is crucial to mitigate these negative outcomes. Yet, we know little about what influences adolescents’ pro-environmental behavior. Research shows that people’s biospheric values and environmental self-identity, elicit personal norms to act environmentally friendly, which can induce a wide range of pro-environmental actions. Yet there is no evidence that these factors can influence pro-environmental behavior of adolescents, because this has only been studied for adults. Given that in adolescence, values, identities and moral structures undergo intense development, the question is whether these factors can motivate adolescents to act pro-environmentally. To address this question, we have conducted three studies with adolescents in Lithuania (Study 1: N = 256; Study 2: N = 349; Study 3: N = 905). We found support that adolescents’ biospheric values and environmental self-identity were associated, via personal norms, with a wide range of pro-environmental behaviors, including recycling, environmentally friendly traveling, purchasing environmentally friendly goods and drinking tap water. Based on theory and the current findings, we suggest directions for policies aimed at promoting pro-environmental behavior of adolescents.

Time preference and personal value: a population-based cross-sectional study in Japan

Objective

This study aimed to investigate the association between time preference (i.e., time discounting and hyperbolic time discounting) and personal values (the areas of priority values and commitment to value) in a sample of adult community residents in Japan.

Methods

Data from respondents (N = 2787) who completed the wave 1 and 3 surveys of a three-wave panel study of adult community residents in municipalities in Tokyo and suburban areas spanning 2010–2017 were analysed. Time discount rate and hyperbolic discount were measured using a three-item choice-based scale at the wave 1. Areas of priority value at present and at age 15 were measured by 11 questions for different value areas at the wave 3; the commitment to value at present and age 15 was measured by the Personal Value Questionnaire-II (PVQ-II) at the wave 3. Linear regression analyses were conducted of priority areas of values and commitment to value on time preference indicators, adjusting for sociodemographic variables and childhood socioeconomic status.

Results

After excluding those with missing responses, data from 1880 and 1958 respondents were subject to analyses on time discounting and hyperbolic time discounting, respectively. Time discount rate was significantly and negatively associated with the value area of maintaining a stable life at present. Hyperbolic time discounting was significantly and negatively associated with the commitment to value at age 15.

Conclusion

There may be an association between time preference and personal values. Time discounting and hyperbolic time discounting may be associated with different aspects of personal values, i.e., area of priority values and commitment to value, respectively.

Assessing the hierarchy of personal values among adolescents: A comparison of rating scale and paired comparison methods

INTRODUCTION

For assessing personal values, the rating scale method may not adequately reflect the hierarchical structure of personal values and tends to be influenced by response style bias. The paired comparison method is considered a promising alternative approach, because it engages comparative judgment and may reduce response style biases. The present study aimed to compare these two methods for assessing the hierarchy of personal values among adolescents.

METHODS

A total of 191 community-dwelling adolescents aged 12-15 years old completed the rating scale and paired comparison version of the Brief Personalized Value Inventory. Descriptive statistics and latent class analyses were used to assess the difference between the rating scale and paired comparison methods.

RESULTS

The two methods yielded similar rankings and means for personal values. The number of subgroups identified by latent class analysis was higher in the paired comparison method than in the rating scale method (10-class vs. 5-class). In the results using the rating scale method, there was a subgroup with high scores on all personal values items.

CONCLUSIONS

The paired comparison method captured substantially more heterogeneity in the hierarchy of personal values among adolescents compared to the rating scale, which may be influenced by response style bias.
