RESUMO

OBJECTIVES: Perceived expectations for active aging (PEAA) reflect subjective exposure to social expectations about staying active and fit in old age, for example, by maintaining health and social engagement. We investigated whether motivational and personality factors were related to PEAA in the domains of physical health, mental health, and social engagement. METHOD: We used a nationally representative sample of German adults (SOEP-IS) covering the entire adult life span (N = 2,007, age range 16-94 years) to test our pre-registered hypotheses. RESULTS: Multiple regression analyses indicated that motivation (i.e. life goals and health-related worries) was consistently associated with PEAA in the matching domains and mediated the effects of openness to experience on PEAA. No other personality trait was associated with PEAA. CONCLUSION: Our findings suggest that individuals preferentially notice the expectations for active aging whose content relates to their personal concerns and goals.

RESUMO

Exposure to expectations for active aging may be modulated by age and individual resources (socioeconomic status, social integration, and health) via multiple pathways. Using a cross-sectional, nationally representative sample of adults aged 17 to 94 (N = 2,007), we investigated the relations between age, individual resources, and perceived expectations for active aging (PEAA) in three domains (physical health, mental health, and social engagement). Across domains, young adults and individuals aged 70+ reported slightly lower PEAA than emerging adults did; no other age differences emerged. Multiple regression showed that a higher subjective socioeconomic status, better perceived general health, and partnership (in older adults) predicted higher PEAA (almost) across domains, whereas church attendance, employment status, and occupational prestige yielded domain- and age-specific effects, which were not always positive. We conclude that the effects of individual resources on PEAA are limited in general but vary depending on life domain and age.

RESUMO

While the study of personality differences is a traditional psychological approach in entrepreneurship research, economic research directs attention towards the entrepreneurial ecosystems in which entrepreneurial activity are embedded. We combine both approaches and quantify the interplay between the individual personality make-up of entrepreneurs and the local personality composition of ecosystems, with a special focus on person-city personality fit. Specifically, we analyse personality data from N = 26,405 Chinese residents across 42 major Chinese cities, including N = 1091 Chinese entrepreneurs. Multi-level polynomial regression and response surface plots revealed that: (a) individual-level conscientiousness had a positive effect and individual-level agreeableness and neuroticism had a negative effect on entrepreneurial success, (b) city-level conscientiousness had a positive, and city-level neuroticism had a negative effect on entrepreneurial success, and (c) additional person-city personality fit effects existed for agreeableness, conscientiousness and neuroticism. For example, entrepreneurs who are high in agreeableness and conduct their business in a city with a low agreeableness level show the lowest entrepreneurial success. In contrast, entrepreneurs who are low in agreeableness and conduct their business in a city with a high agreeableness level show relatively high entrepreneurial success. Implications for research and practice are discussed.

RESUMO

OBJECTIVE: Taking into account the regional context, we investigated whether social comparison in coping with occupational uncertainty served self-improvement (i.e., adaptive coping) or self-enhancement (i.e., subjective well-being). METHOD: Respondents were 620 German adults aged 16 to 43, 59% female, who participated in three yearly follow-ups of a larger survey. The number of observations was 1,309 for contemporaneous and 1,079 for longitudinal analyses. Participants reported on perceived occupational uncertainty (e.g., risk of losing a job and difficulties with career planning), strategies for coping with it, and whether, and in which direction, they made social comparisons in coping with occupational uncertainty. RESULTS: Making social comparisons (vs. not) was associated with higher goal engagement and lower goal disengagement. Upward (as opposed to downward) comparison prospectively predicted higher goal engagement. Under high regional unemployment, upward comparison prospectively predicted lower goal disengagement, whereas making social comparisons was contemporaneously associated with higher subjective well-being. Higher regional unemployment rates predicted more frequent comparison, whereas comparison direction was predicted only by situational variables, especially personal control over the outcomes. CONCLUSIONS: When operationalized as a conscious mental action and put in the context of coping with occupational uncertainty, social comparison serves primarily self-improvement.

RESUMO

We investigated the interplay between the personality trait exploration and objective socioecological conditions in shaping individual differences in the experience of two individual-level benefits of current social change: new lifestyle options, which arise from the societal trend toward individualization, and new learning opportunities, which accrue from the societal trend toward lifelong learning. We hypothesized that people with higher trait exploration experience a greater increase in lifestyle options and learning opportunities--but more so in social ecologies in which individualization and lifelong learning are stronger, thus offering greater latitude for exploring the benefits of these trends. We employed structural equation modeling in two parallel adult samples from Germany (N = 2,448) and Poland (N = 2,571), using regional divorce rates as a proxy for individualization and Internet domain registration rates as a proxy for lifelong learning. Higher exploration was related to a greater perceived increase in lifestyle options and in learning opportunities over the past 5 years. These associations were stronger in regions in which the trends toward individualization and lifelong learning, respectively, were more prominent. Individuals higher in exploration are better equipped to reap the benefits of current social change--but the effects of exploration are bounded by the conditions in the social ecology.

RESUMO

It is widely believed that warm and supportive parenting fosters all kinds of prosocial behaviors in the offspring, including civic engagement. However, accumulating international evidence suggests that the effects of family support on civic engagement may sometimes be negative. To address this apparent controversy, we identified several scenarios for the negative effects of supportive parenting on youth civic engagement and tested them using four waves of data from the Finnish Educational Transitions Studies. They followed 1549 students (55 % female) from late adolescence into young adulthood, included both maternal (n = 231) and offspring reports of parental support, and assessed civic engagement in young adulthood. Control variables included socioeconomic status, other sociodemographic indicators, church belonging, personality traits, and earlier civic engagement. Higher maternal warmth and support and a stronger identification with the parental family in adolescence predicted offspring's lower political activism up to 10 years later. Perceived parental support in young adulthood predicted lower volunteering 2 years later. There were no significant effects on general organizational involvement (e.g., in student and hobby associations). None of the a priori scenarios that we identified from the literature appeared to explain the pattern of results satisfactorily. We put forth cultural and life stage explanations of our findings.

RESUMO

Technology developments have changed immigrants' adaptation patterns in modern societies, allowing immigrants to sustain dense, complex connections with homeland while adjusting in the host country, a new phenomenon termed transnationalism. As empirical studies on immigrant transnationalism are still scarce, the purpose of this study was to investigate mean levels and determinants of a core component of transnationalism-transnational travel. Hypotheses were based on context of exiting homeland, living conditions in Germany and demographic and sociocultural variables. Transnational travel behaviour was assessed as frequency of return trips in three immigrant groups in Germany: ethnic Germans, Russian Jews and Turks. Interviews were conducted with 894 women participants from these groups. Results showed substantial transnational travel behaviour in all groups with Turks reporting higher levels than ethnic Germans and Russian Jews. Interindividual differences in transnational travel within groups were also examined. Results indicated similarities (e.g. network size in home country related positively to transnational travel frequency in all groups) and group-specific associations (e.g. co-ethnic identifying related positively to transnational travel frequency among Turks, but negatively for the other groups). Our study highlights the need for a new understanding of immigration and emphasises the consideration of group-specific mechanisms in transnational travel behaviour.

RESUMO

Increasingly, adolescents are growing up in multiethnic multicultural societies. While intergroup prejudice can threaten the multicultural societal cohesion, intergroup friendships are strong predictors of reduced prejudice. Thus, more research is needed to fully understand the development of intergroup friendships and their relations to less prejudicial attitudes. This study addressed two major developmental research questions: first, whether longitudinal patterns of intergroup friendships of native adolescents (i.e., whether or not a native German adolescent has a friendship with an immigrant at different points in time) relate to changes in rates of prejudice about immigrants. Second, whether these friendship patterns that unfold over time can be predicted by contact opportunities, attitudes, subjective norms, and perceived behavioral control assessed at the beginning of the study. The sample included 372 native German adolescents (14.7 years of age at first assessment, 62.3% girls) who showed one of four friendship trajectories over the three annual assessments: they either maintained, gained, never had, or lost a friendship with an outgroup peer. In particular, results showed that adolescents who gained an intergroup friendship over the three time points showed a significant decrease in negative prejudice over the study. All four theorized predictors contributed to explain friendship trajectory membership. Generally, adolescents with many opportunities for contact, positive attitudes about contact, perceived positive social norms for contact, and high levels of behavioral control (self-efficacy) were more likely to maintain a friendship with an outgroup member than to follow any of the three other friendship trajectories (gain, lost, or never had). The pattern of predictions differed, however, depending on the specific pairs of friendship trajectories compared.

RESUMO

This study investigated how religiosity relates to goal engagement (i.e., investing time and effort; overcoming obstacles) and goal disengagement (i.e., protecting self-esteem and motivational resources against failure experiences; distancing from unattainable goals) in coping with perceived work-related uncertainties (e.g., growing risk of job loss) that arise from current social change. We hypothesised that religiosity not only expands individuals' capacities for both engagement and disengagement but also fosters an opportunity-congruent pattern of engagement and disengagement, promoting engagement especially under favourable opportunities for goal-striving in the social ecology and facilitating disengagement especially under unfavourable opportunities. Multilevel analyses in a sample of N = 2089 Polish adults aged 20-46 years partly supported these predictions. Religiosity was associated with higher goal engagement, especially under favourable economic opportunities for goal-striving in the social ecology (as measured by the regional net migration rate). For disengagement, the results were more mixed; religiosity was related to higher self-protection independently of the economic opportunity structure and predicted higher goal-distancing only under the most unfavourable opportunities. These results suggest that religiosity can promote different coping strategies under different conditions, fostering a pattern of opportunity-congruent engagement and, to some extent, disengagement that is likely to be adaptive.

RESUMO

The identification of salient risk factors for alcohol consumption among male and female adolescents is an important topic not only for etiology research but also for designing effective gender-specific alcohol prevention programs for young people. This study examined the extent to which problematic alcohol use trajectories from ages 14 to 18 among male and female youth were related to childhood predictors assessed at age 9 (i.e., impulsivity, academic self-confidence, social problems with peers), socio-demographic variables, and mid-adolescent correlates [i.e., parental use, body mass index (BMI), risky peer context, conduct problems at school, parent-child relationship, somatic complaints]. Data analysis was based on a representative German longitudinal study (1986-1995, n = 1,619, 55 % female). Using growth mixture modeling methodology, associations of childhood predictors and mid-adolescent correlates to distinctive trajectories of alcohol use were examined for males and females separately. For males, a problematic consumption trajectory was associated with poor relationships to parents in adolescence and small community size. For females, low impulsivity during childhood, high BMI, and contact with deviant peers during adolescence predicted problematic as compared to normative alcohol use trajectories. Additionally, high parental alcohol use, low parental educational background, and conduct problems at school during adolescence were common predictors of a problematic alcohol use trajectory in both genders. The results provide insights regarding differences in the gender-typical development of adolescent alcohol use as well as stress the need of gender-specific intervention components along with universal prevention strategies against problematic consumption trajectories.

RESUMO

OBJECTIVE: We investigated the relationship between dispositional optimism and coping with growing occupational uncertainty, drawing on the life span theory of control to assess coping. METHOD: Participants were 606 German adults with various sociodemographic backgrounds, aged 16-43. They were interviewed at the end of 2005 (Time 1) and at the beginning of 2007 (Time 2). We regressed each control strategy at Time 2 on its scores at Time 1, optimism at Time 1, three moderating variables, and their interactions with optimism. RESULTS: Dispositional optimism predicted an increase in both goal engagement strategies (selective primary and compensatory primary control) only under favorable conditions (low regional unemployment rate, low perceived growth in occupational uncertainty, and high perceived controllability of this stressor). Specific conditions moderating the effects of optimism differed between the two engagement strategies. In addition, an unfavorable labor market situation as such prompted an increase in goal engagement. No effects of optimism on goal disengagement (compensatory secondary control) at Time 2 were found. CONCLUSIONS: The effects of dispositional optimism on the change in control strategies were contingent on the labor market situation, which supports the view that optimists are better able to tailor their coping responses to available opportunities.

RESUMO

This paper investigates the association between perceptions of broader changes in the social-ecological context and individuals' subjective well-being (SWB). Macro-level societal changes such as globalization or demographic change give rise to new demands for individual functioning at work and/or in the family. Such new demands associated with social change are stressful and likely to be related to lower levels of SWB. Being active agents, individuals attempt to deal with social change and its increasing demands to protect their SWB. The present study investigates which kinds of control strategies are most effective in protecting one's SWB. Specifically, we predicted that control strategies of goal engagement will be most effective under conditions of perceived high control, and control strategies of goal disengagement will be most effective under conditions of perceived low control. In a large sample of 2537 German adults, work- and family-related demands associated with social change were found to be negatively linked to SWB. Moreover and in line with the motivational theory of lifespan development, control strategies of goal engagement and disengagement were beneficial for SWB to the extent that they matched the perceived control of the demands associated with social change.

RESUMO

This longitudinal study compared immigrant and native adolescents' expectations concerning the timing of conventional socially acceptable and oppositional less socially acceptable forms of autonomy. Based on normative development and a collectivist background among immigrants, both developmental and acculturative change was expected. The sample consisted of 523 ethnic German immigrants from the former Soviet Union and 475 native German adolescents, both groups divided into an early (age 12.5years) and a late (age 16years) adolescent group. Results revealed more developmental than acculturative change, as immigrants and natives mostly showed a similar rate of change in autonomy expectations. Acculturative change was found only for oppositional autonomy among late adolescent immigrants, whose later expectations approached those of their native age-mates over time.

RESUMO

Drawing on the theory of planned behavior (TPB) and the volunteer process model (VPM), we compared proximal (the TPB variables) and distal (general social support and sense of community) antecedents and quality of experience between civic (CP) and political (PP) participation. Outcome variables were future intentions. We used data from a mail survey of 3,231 adults with or without prior CP or PP experience. Both inexperienced and experienced individuals perceived PP more negatively than CP. Quality of experience was also rated substantially more negatively for PP than for CP. Distal antecedents had similar effects for CP and PP, but they were mostly significant for CP only. In line with the VPM, quality of experience was the strongest predictor of future intentions in experienced individuals. Perceived behavioral control was the strongest mediator. Findings corroborate the distinction between CP and PP and suggest that PP is much less attractive on average.

RESUMO

This research note addresses the current and potential future role of psychologists in the study of international migration. We review ways in which psychologists have contributed to the study of migration, as well as ways in which psychological scholarship could be integrated with work from other social science fields. Broadly, we discuss four major contributions that psychology brings to the study of international migration-studying migrants' internal psychological experiences, incorporating a developmental perspective, conducting experimental studies, and integrating across levels of analysis. Given the position of psychology as a 'hub science' connecting more traditional social sciences with health and medical sciences, we argue for a more prominent role for psychologists within the study of international migration. Such a role is intended to complement the roles of other social scientists and to create a more interdisciplinary way forward for the field of migration studies. The research note concludes with an agenda for further scholarship on migration.

RESUMO

Affective influences may play a key role in adolescent risk taking, but have rarely been studied. Using an audiovisual method of affect induction, two experimental studies examined the effect of positive affect on risk perceptions in adolescence and young adulthood. Outcomes were risk perceptions regarding drinking alcohol, smoking a cigarette, riding in a car with a drunk driver, getting into a fight, and having unprotected sexual intercourse. Study 1 showed that positive affect led to lower risk perceptions than neutral affect for young adults (mean age 23). Study 2 replicated the effect for early adolescents (mean age 13), mid-adolescents (mean age 17), and young adults (mean age 23). Moreover, Study 2 showed that the effect was most pronounced at high levels of impulsiveness. Adolescents and young adults may be more risk averse in contexts that do not give rise to emotions, but have markedly lower risk perceptions under positive affect.

RESUMO

Drawing on two nationally representative German studies (N(1) = 1744, N(2) = 759), we examined correlates of early, on-time, and late curfew autonomy, a retrospective indicator of behavioural autonomy, in young and middle adulthood (19-37 years of age). Adjustment in four domains was considered: educational attainment, externalizing problem behaviour, subjective well-being, and interpersonal relationships. The early group showed lower adjustment in multiple domains across young and middle adulthood. The late group reported a mixed pattern of adjustment at younger ages (lower externalizing problems, but lower positive affect, lower importance of peers, and lower likelihood to have a partner) and positive adjustment in all domains at older ages. Timing effects were controlled for sociodemographic characteristics and retrospective measures of early adversities, pubertal timing, disclosure to parents, and peer group affiliation in adolescence. Findings show that late behavioural autonomy in its correlates is not simply the opposite of early behavioural autonomy.

RESUMO

The present study investigated whether a life skills program (LSP) for the prevention of adolescent substance misuse can have positive influences on a school context and on school bonding. The study also explored whether effects on alcohol use are mediated by positive effects on school bonding resulting from program participation. The LSP IPSY (Information+Psychosocial Competence=Protection) was implemented over a 3-year period via specially trained teachers. Analyses were based on a German evaluation study utilizing a quasi-experimental design (intervention/control) with school-wise assignment to the respective groups. Analyses were based on four measurement points (N=952, 10 years at pre-test). Results indicated that IPSY was well implemented, highly accepted by teachers and students, and that teachers profited regarding their teaching methods. ANCOVAS revealed positive program effects on alcohol use and school bonding. Multiple regressions indicated that positive influences on school bonding following program participation partially mediated effects on alcohol use.
