Does Employment Status Matter for Emerging Adult Identity Development and Life Satisfaction? A Two-wave Longitudinal Study.

Late emerging adulthood is pivotal for identity exploration and development and is interrelated with life satisfaction. In the development of identity and life satisfaction, it is important to have a stable employment status that supports the foundation of life. However, the interrelationships among identity, life satisfaction, and employment status in late emerging adulthood are unclear. Using a two-wave longitudinal survey, this study examined identity development and whether the relationship between identity and life satisfaction varies by employment status. Participants included 875 Japanese emerging adults (65.5% women, Mage = 24.74, SDage = 0.44). Multivariate analysis of variance showed that identity synthesis decreased for those who lost their jobs or those who changed from being full-time to part-time employment. Additionally, individuals with full-time employment had higher identity synthesis and lower confusion than those with part-time or no employment. Multi-group path analysis indicated that identity synthesis was positively associated with life satisfaction and confusion was negatively associated, and these relationships did not differ by employment status. These findings suggest that identity development in late emerging adulthood varies by employment status and that the association between identity and life satisfaction may not be moderated by employment status. Overall, this study contributes to elucidating the characteristics of identity development along employment status and its relationship to life satisfaction in late emerging adulthood.

Relationship between Personality Traits and Subjective Well-Being in Emerging Adulthood: Moderating Role of Independent and Interdependent Self-Construal.

During emerging adulthood, individuals' subjective well-being declines owing to challenges regarding identity, work, and romantic relationships. Although the relationships among personality traits, self-construal, and well-being have been examined, studies have focused on personal rather than relational subjective well-being. Furthermore, self-construal's moderating effect on the relationship between personality traits and subjective well-being remains unclear. Therefore, this study examined the relationships among the Big-five personality traits and subjective well-being (life satisfaction, happiness, and interdependent happiness) and the moderating effect of self-construal among 1548 Japanese emerging adults (Mage = 22.24, SD = 1.01). Regression analysis indicated that all aspects of subjective well-being were negatively associated with neuroticism and positively associated with extraversion, independent and interdependent self-construal. Further, agreeableness was positively associated with personal and relational well-being. Independent or interdependent self-construal can moderate the relationships between neuroticism, extraversion, and agreeableness and subjective well-being. Overall, these findings provide valuable insights for improving Japanese emerging adults' well-being.

Patterns of Personality Development and Psychosocial Functioning in Japanese Adolescents: A Four-Wave Longitudinal Study.

While patterns of adolescent personality development are country-specific, previous studies that have examined them have been limited to the Netherlands and Finland. This study aimed to identify the patterns of personality development and examine the relationship between these patterns and psychosocial functioning among Japanese adolescents. Overall, 618 Japanese adolescents (49.5% girls; 16 years) participated in the annual longitudinal survey from 2013 to 2016. Using latent class growth analysis, the following four patterns of personality development were identified: resilient, over-controlled, vulnerable, and moderate. Although the mean-level changes in the Big Five domains were generally insignificant among the four patterns, the vulnerable pattern showed a progressive increase in conscientiousness, and the moderate pattern showed a decrease in neuroticism and an increase in conscientiousness. Furthermore, multivariate analysis of variance tests indicated that the resilient pattern showed higher subjective well-being and lower psychosocial problems than the other personality patterns; the over-controlled pattern showed higher internalizing problems than the resilient pattern; the vulnerable pattern showed lower subjective well-being and higher internalizing problems than the other patterns; and the moderate pattern scored between the resilient, over-controlled, and vulnerable patterns in both subjective well-being and psychosocial problems. These findings suggest that the vulnerable and moderate patterns, which are immature patterns compared to the resilient and over-controlled ones, showed positive changes to the direction of maturity from middle to late adolescence in Japan.

Adolescents' Identity Development Predicts the Transition and the Adjustment to Tertiary Education or Work.

Although identity development is crucial in individuals' psychological adjustment from adolescence to adulthood, little is known about its impact in the transition to tertiary education or work. This study examined whether identity development during high school predicts career choices and adjustment (i.e., engagement) and maladjustment (i.e., burnout) after graduation. A total of 357 Japanese adolescents participated throughout the 3-year period of vocational high school (Mage = 15.75; 62.75% girls). A follow-up assessment, at 18 months after the school-to-tertiary education or school-to-work transitions, was conducted. Higher identity synthesis during high school years predicted entry into tertiary education, while higher identity confusion predicted transition to work. Furthermore, higher identity synthesis during the high school years predicted higher post-graduation academic engagement, and higher levels of identity confusion predicted higher levels of post-graduation academic or work burnout. Overall, this study contributes to the understanding of the role of identity development in adolescence as a valuable asset for predicting the transition and the adjustment to tertiary education or work.

Profiles of Emotional Separation and Parental Trust from Adolescence to Emerging Adulthood: Age Differences and Associations with Identity and Life Satisfaction.

Youth become psychologically independent by emotionally separating from their parents and simultaneously developing a sense of trust in them. While these relational components have been addressed separately, studies focusing on the change in dynamics of these components are lacking. This study examined profiles of parent-youth relationship quality based on emotional separation and parental trust, age differences in the prevalence of these profiles, and age differences in the associations between the profiles, identity, and life satisfaction. Participants included 14,428 youth living in Japan from five age groups (44.8% girls/women; Mage = 20.6 years; range = 12-25 years). Six profiles were identified: healthy-independent, unhealthy-independent, balanced, moderate/ambivalent, connected, and distant. The connected profile was predominant among early adolescents, while the healthy-independent profile was predominant among late adolescents and early and middle emerging adults. Among all age groups, identity synthesis was the highest in the healthy-independent profile, and life satisfaction was the highest and identity confusion was the lowest in the healthy-independent and connected profiles. These findings indicate that young people navigate the process of becoming independent from their parents by balancing emotional separation and parental trust, and this balance relates to identity development and life satisfaction.

Direction of associations between personality traits and educational identity processes: Between- and within-person associations.

INTRODUCTION: In adolescence, personality traits and educational identity processes are interwoven. Previous studies have shown that personality traits predict healthy identity commitment and exploration in education. However, the direction of associations between personality traits and an identity process that searches for another identity option (i.e., reconsideration of commitment) is unclear. Furthermore, there is a lack of prospective studies regarding the direction of the association between personality traits and the educational identity process using within-person methods. Therefore, this study examined the direction of these associations. METHODS: Participants of this four-wave longitudinal study comprised 618 Japanese 13-year-old adolescents (53.3% girls). This study involved a 1-year-interval assessment. RESULTS: Cross-lagged panel models (CLPM) indicated that four personality traits (neuroticism, agreeableness, and conscientiousness) predicted three educational identity processes, while reconsideration of commitment predicted two personality traits (i.e., neuroticism and conscientiousness). Random intercept cross-lagged panel models (RI-CLPM) indicated that agreeableness predicted healthy commitment, while commitment predicted agreeableness at within-person level. CONCLUSION: The findings from CLPM suggest that reconsideration of commitment is a significant factor to predict healthy (i.e., conscientiousness) and unhealthy (i.e., neuroticism) personality traits in individual differences. Furthermore, the findings from RI-CLPM suggest that agreeableness may be a key trait in promoting healthy educational identity commitment. Theoretical and practical implications of these findings are discussed.

Daily Identity Processes and Emotions in Young Adulthood: a Five-Day Daily-Diary Method.

The process of exploring and committing to one's identity for the sake of a future-oriented goal is important for young adults' psychosocial functioning. Whereas the relationship between identity process and psychosocial functioning has been examined in long-term longitudinal studies, the short-term relationship between the two at the daily level has not been clarified. This study developed a measure of daily-level identity process and examined their relationship with daily positive and negative emotions, using a five-day daily-diary method. The participants included 721 Japanese young adults aged 18-30 years (54.4% female, Mage = 26.05 years). Results indicated the measure's three-factor structure, including commitment, active exploration, and ruminative exploration. Commitment related positively to life satisfaction and happiness, and negatively related to depression. Active exploration and ruminative exploration indicated negative associations with life satisfaction and happiness, and positive association depression. Latent profile analysis extracted five theoretically meaningful identity profiles at the daily level: foreclosure, moratorium, troubled diffusion, searching moratorium, and carefree diffusion. Logistic regression analyses indicated that troubled diffusion and moratorium, and foreclosure profiles showed lower and higher levels of life satisfaction and happiness, respectively. These results provided evidence of a strong link between young adult's identity processes, profiles, and positive and negative emotions at the everyday level. Implications and suggestions for future research are discussed.

Diverse-and-Dynamic Pathways in Educational and Interpersonal Identity Formation during Adolescence: Longitudinal Links With Psychosocial Functioning.

This study aimed to examine the relations between educational and interpersonal identity trajectories and psychosocial functioning based on a three-factor identity process model. A total of 968 Japanese adolescents including 13- and 16-years-olds (49.7% female) participated in a four-wave longitudinal study. Latent class growth analysis extracted five identity trajectories in each educational and interpersonal identity domain and revealed (a) high prevalence of low commitment identity trajectories, (b) absence of the closure trajectory, and (c) changeable identity trajectories that have not been identified in Western context (i.e., the Netherlands). Furthermore, a latent change model revealed dynamic relations between identity trajectories and psychosocial functioning. These findings provide critical insights into the diverse and dynamic pathways of identity formation during adolescence in Japan.

Emotional separation, parental trust, and psychosocial adjustment in preadolescence and early adolescence.

INTRODUCTION: Emotional separation and parental trust are two fundamental components of parent-adolescent relationships across different cultural contexts. Previous research showed that emotional separation hindered adolescents' psychosocial adjustment, while parental trust benefited it. However, research on preadolescence is lacking. Preadolescence is a crucial period, as theories and findings suggest that too early autonomy around puberty had negative consequences for psychosocial adjustment. This study focused on preadolescence and early adolescence and tested two hypotheses: that emotional separation would be negatively, and parental trust would be positively, associated with psychosocial adjustment, and that this pattern of associations would be more salient in preadolescence than in early adolescence. METHODS: Participants were 856 preadolescent elementary schoolers (49.6% girls; age range 9-12 years, Mage = 10.79, SD = 0.92) and 518 early adolescent junior high schoolers (47.7% girls, age range 12-15 years; Mage = 13.56, SD = 0.98) in Japan, who completed measures of emotional separation, parental trust, and psychosocial adjustment (industry, school adaptation, and daily life behaviors). RESULTS: Emotional separation was negatively associated with reviewing learning contents and doing homework. Parental trust was positively associated with industry, school adaptation, waking up at regular times, and observing rules at school. These relationships did not differ between age groups. CONCLUSIONS: This study highlights that emotional separation has a negative relationship, and parental trust has a positive relationship, with psychosocial adjustment throughout preadolescence and adolescence.

Do Identity Processes and Psychosocial Problems Intertwine with Each Other? Testing the Directionality of Between- and Within-Person Associations.

As forming and evaluating commitments are stressful processes, adolescents who worry about their identity may exhibit psychosocial problems. However, there is a lack of prospective research regarding the direction of associations between the processes of identity and psychosocial problems in the future domain. This study examined the direction of relationships between future-oriented identity processes and psychosocial problems based on a five-dimensional identity process model. A total of 347 Japanese 14-year-old adolescents (53.3% female) participated in a three-wave longitudinal study with a one-year-interval assessment. Standard cross-lagged models indicated that pro-active identity exploration was negatively predicted by conduct problems, and ruminative exploration was positively predicted by depressive symptoms. Within-person cross-lagged models indicated that ruminative exploration positively predicted both depressive symptoms and conduct problems at the within-person level. These findings reveal how identity processes and psychosocial problems are interwoven during adolescence.

Longitudinal Links Between Identity Consolidation and Psychosocial Problems in Adolescence: Using Bi-Factor Latent Change and Cross-Lagged Effect Models.

Most previous identity research has focused on relationships between identity synthesis, confusion, and psychosocial problems. However, these studies did not take into account Erikson's notion of identity consolidation, that is, the dynamic interplay between identity synthesis and confusion. This study aimed to examine longitudinal relationships and the directionality of the effects between identity consolidation and psychosocial problems during adolescence, using two waves of longitudinal data from 793 Japanese adolescents (49.7% girls; ages 13-14 and 16-17 at Time 1). A bi-factor latent change model revealed that levels and changes in identity consolidation were negatively associated with levels and changes in psychosocial problems. Furthermore, a bi-factor cross-lagged effects model provided evidence that identity consolidation negatively predicted psychosocial problems, and vice versa. Our study facilitates a better understanding of the importance of identity consolidation in the relations between identity components and psychosocial problems.

A Cross-Cultural Perspective on the Relationships between Emotional Separation, Parental Trust, and Identity in Adolescents.

Emotional separation and parental trust in parent-adolescent relationships are important factors for adolescent identity formation. However, prior research findings on emotional separation are inconsistent. This study aimed to conduct a more rigorous examination of the associations of emotional separation and parental trust with identity synthesis, confusion, and consolidation by applying a bi-factor model to identity, using adolescent samples from Lithuania (N = 610; 53.9% female; M age = 14.92), Italy (N = 411; 57.4% female; M age = 15.03), and Japan (N = 759; 43.7% female; M age = 14.13). Structural equation modeling revealed that emotional separation and parental trust were consistently associated with identity consolidation across the three countries, rather than associated with identity synthesis and identity confusion. Furthermore, the patterns of associations of emotional separation and parental trust with identity synthesis and identity confusion differed across the three nations. Overall, this study provides a better understanding of the role of emotional separation and parental trust in adolescent identity formation by suggesting the importance of the identity consolidation in the association between parent-child relationships and identity formation across three countries.

Looking at the dark and bright sides of identity formation: New insights from adolescents and emerging adults in Japan.

The aim of the present study was to gain new insights into the dark and bright sides of identity formation with a sample of 1851 Japanese adolescents and emerging adults, applying a three-dimensional model of identity formation (i.e., commitment, in-depth exploration, and reconsideration of commitment). By means of cluster analysis, we identified five statuses that strongly resembled statues extracted in prior research with Western youth: achievement, foreclosure, moratorium, diffusion, and searching moratorium. We found that each status reported a distinct profile in terms of personality and psychosocial problems. Importantly, we found that the searching moratorium status was adaptive in adolescence but not in emerging adulthood. These results suggest that the five statuses are replicable in Japanese adolescents and emerging adults, and that the searching moratorium status presents a combination of the bright and dark sides whose prevalence varies with age. Clinical implications for identity research and intervention programs are discussed.

[Researching identity development and statuses with the Dimensions of Identity Development Scale: the Japanese version].

The Dimensions of Identity Development Scale (DIDS) provides a new method of researching identity development based on the dual-process model pertaining to lifespan development. This study developed and evaluated the Japanese version of this scale (DIDS-J). Two surveys of undergraduate and high school students showed that the DIDS-J had good reliability and validity and that it consisted of 25 items with five factors: commitment making, identity with commitment, exploration in breadth, exploration in depth, and ruminative exploration. Through cluster analysis of the DIDS-J, five identity statuses were found that were not clearly distinguished by previous scales: foreclosure, achievement, searching moratorium, diffused diffusion, and carefree diffusion. Research using the DIDS-J has two advantages: it enables us to examine the process of identity development among adolescents with a wider age range, and to compare results cross-culturally in future research. The trial investigations compared student scores with those from previous research in Western cultures, demonstrating that DIDS-J may lead to further explanations of identity development.

[Examining the reliability and validity of a Japanese version of the 12-item Erikson Psychosocial Stage Inventory (the 5th stage)].

This study aimed to develop a 12-item version of the Erikson Psychosocial Stage Inventory (the 5th stage) (EPSI (5th)) and examine its reliability and validity. University students (N = 545) participated in this study. Confirmatory factor analyses revealed that a two-factor model provided a better fit than alternative one-factor models. An analysis of Cronbach's α coefficients and the test-retest method showed acceptable scale reliability. In accordance with our hypotheses, correlation analyses revealed that the EPSI (5th) subscale scores (i.e., synthesis and confusion) were significantly related to measures of self-esteem, life satisfaction with life, and identity confusion. Implications and suggestions for future research are discussed.

Motivation to lead in Japan: validation of a Japanese version of the motivation to lead scale.

Introduction: This study aimed to develop a Japanese version of the motivation to lead (MTL) scale consisting of three factors-affective-identity MTL, non-calculative MTL, and social-normative MTL-and examine its construct validity and reliability. Methods: The participants comprised 500 university students and 500 employees aged 20-29 years registered with a Japanese research company. Results: Based on a confirmatory factor analysis, the three-factor model was found to be appropriate for the Japanese context. The measurement invariance analyses indicated scalar invariance between students and employees and between men and women. Finally, the correlation analysis with the Big Five personality traits conducted to examine construct validity indicated that affective-identity MTL and social-normative MTL had significant relationships with all five traits (extraversion, agreeableness, conscientiousness, open-mindedness, and negative emotionality). Although non-calculative MTL was not significantly correlated, it can be interpreted in the Japanese context. Discussion: The results indicate the adequate construct validity and reliability of the Japanese version of the MTL scale. These findings hold significant implications for leadership development and selection in Japan, highlighting the motivational factors that drive effective leadership.

Validation of the Japanese version of the revised version of the compound psychological capital scale (CPC-12R).

This study developed a Japanese version of the Revised Version of the Compound Psychological Capital Scale (CPC-12R) and tested its reliability and construct validity. The participants were 1,000 young adults (500 university students and 500 employees) recruited through an internet survey. Confirmatory factor analysis showed that the four first-order factors (hope, optimism, resilience, and self-efficacy) and one second-order factor (PsyCap) model of the previous study is appropriate for the Japanese context. In addition, Cronbach's α and omega-higher-order of CPC-12R were sufficient. The measurement invariance analysis suggested sufficient scalar invariances for the employees and university students and across genders. The Japanese version of the CPC-12R had moderate positive correlations with job satisfaction, work engagement, conscientiousness, and extraversion, as well as a moderate negative correlation with negative emotionality. These findings provide evidence for sufficient reliability and construct validity of the Japanese version of the CPC-12R.

Trajectories in sense of identity and relationship with life satisfaction during adolescence and young adulthood.

Previous research on identity development among adolescents has focused on the processes involved. However, it is unclear how the sense of identity (synthesis and confusion) develops and how it relates to life satisfaction. This study aims to examine the relationship between sense of identity and life satisfaction among Japanese youth living in the urban Kanto, Kansai, and Chubu areas. A total of 5,047 Japanese youth (49.7% female; Time 1 Mage = 17.08 years, range = 12-22 years) in four age groups (early adolescence, middle adolescence, late adolescence, and young adulthood) participated in a three-wave longitudinal study. Latent growth modeling (LGM) analysis revealed that from early to middle adolescence, synthesis continued to be higher than confusion, whereas from late adolescence to young adulthood, confusion tended to be higher than synthesis. The results of the LGM further showed that the change in synthesis was positively related to the change in life satisfaction and the change in confusion was negatively related to it in all age groups. Using latent class growth analysis (LCGA), five identity classes were extracted: high synthesis-low confusion, low synthesis-high confusion, high synthesis-high confusion, low synthesis-low confusion, and moderate synthesis-moderate confusion. LCGA revealed that youth in the high synthesis classes had a higher sense of life satisfaction than did youth in high confusion classes. These findings provide critical insights into trajectories of identity formation and the relationship between identity development and life satisfaction among Japanese youth that can inform future research and programs designed to facilitate their identity formation.

Association between long-range temporal correlations in intrinsic EEG activity and subjective sense of identity.

The long-range temporal correlation (LRTC) in resting-state intrinsic brain activity is known to be associated with temporal behavioral patterns, including decision making based on internal criteria such as self-knowledge. However, the association between the neuronal LRTC and the subjective sense of identity remains to be explored; in other words, whether our subjective sense of consistent self across time relates to the temporal consistency of neural activity. The present study examined the relationship between the LRTC of resting-state scalp electroencephalography (EEG) and a subjective sense of identity measured by the Erikson Psychosocial Stage Inventory (EPSI). Consistent with our prediction based on previous studies of neuronal-behavioral relationships, the frontocentral alpha LRTC correlated negatively with identity confusion. Moreover, from the descriptive analyses, centroparietal beta LRTC showed negative correlations with identity confusion, and frontal theta LRTC showed positive relationships with identity synthesis. These results suggest that more temporal consistency (reversely, less random noise) in intrinsic brain activity is associated with less confused and better-synthesized identity. Our data provide further evidence that the LRTC of intrinsic brain activity might serve as a noise suppression mechanism at the psychological level.

Is adolescence a period of identity formation for all youth? Insights from a four-wave longitudinal study of identity dynamics in Japan.

In the present study, we examined changes in identity dynamics during adolescence using the Dimensions of Identity Development Scale (DIDS), focusing on social and cultural factors possibly affecting identity formation. Identity formation among adolescents outside Western countries is largely unexplored; therefore, we focused on adolescents in Japan. We conducted a longitudinal study with 4 annual measurement points examining 968 Japanese adolescents (49.7% females). Two cohorts of participants were 13 and 16 years old at Time 1 and were followed until 16 and 19 years old, respectively. Latent class growth analysis extracted 3 identity trajectories corresponding to those found in previous research (i.e., achievement, troubled diffusion, and carefree diffusion) and 2 transitional trajectories newly identified in the present study (i.e., troubled diffusion-to-moratorium and moratorium-to-achievement). Adolescents following the achievement trajectory showed the best subjective well-being, whereas troubled diffused adolescents showed the worst. Furthermore, early-to-middle adolescents and urban adolescents tended to follow a low-commitment trajectory, whereas middle-to-late adolescents and rural adolescents tended to follow a high-commitment trajectory. These findings suggest that identity development proceeds toward integration during adolescence, but simultaneously, diverse developmental trajectories exist and incorporate contextual factors. Thus, in Japan, adolescence may be a period of identity formation for some adolescents, but not for others. (PsycINFO Database Record
