Emerging late adolescent friendship networks and Big Five personality traits : a social network approach

The current study focuses on the emergence of friendship networks among just-acquainted individuals, investigating the effects of Big Five personality traits on friendship selection processes. Sociometric nominations and self-ratings on personality traits were gathered from 205 late adolescents (mean age=19 years) at 5 time points during the first year of university. SIENA, a novel multilevel statistical procedure for social network analysis, was used to examine effects of Big Five traits on friendship selection. Results indicated that friendship networks between just-acquainted individuals became increasingly more cohesive within the first 3 months and then stabilized. Whereas individuals high on Extraversion tended to select more friends than those low on this trait, individuals high on Agreeableness tended to be selected more as friends. In addition, individuals tended to select friends with similar levels of Agreeableness, Extraversion, and Openness.

Maturation of personality in adolescence.

The present research assesses adolescent personality maturation by examining 3 measures of change and stability (i.e., mean-level change, rank-order stability, and profile similarity) of Big Five personality traits, employing data from a 5-annual-wave study with overlapping early to middle (n = 923) and middle to late (n = 390) adolescent cohorts. Results indicated that mean levels of Agreeableness and Emotional Stability increased during adolescence. There was mixed evidence for increases in Extraversion and Openness. Additionally, rank-order stability and profile similarity of adolescent personality traits clearly increased from early to late adolescence. For all change facets, the authors found evidence for gender differences in the timing of adolescent personality maturation, as girls were found to mature earlier than boys.

Different types of Internet use, depression, and social anxiety : the role of perceived friendship quality

The current study examined the longitudinal associations of time spent on Internet activities for communication purposes (i.e., IM-ing) versus time spent on Internet activities for non-communication purposes (i.e., surfing) with depression and social anxiety, as well as the moderating role of perceived friendship quality in these associations. Questionnaire data were gathered from 307 Dutch middle adolescents (average age 15 years) on two waves with a one-year interval. For adolescents who perceive low friendship quality, Internet use for communication purposes predicted less depression, whereas Internet use for non-communication purposes predicted more depression and more social anxiety. These results support social compensation effects of IM-ing on depression and poor-get-poorer effects of surfing on depression and social anxiety, respectively.

Developmental Changes in Adolescents’ Perceptions of Relationships with Their Parents

This 4-wave longitudinal study examines developmental changes in adolescents’ perceptions of parent–adolescent relationships by assessing parental support, conflict with parents, and parental power. A total of 951 early adolescents (50.4% boys) and 390 middle adolescents (43.3% boys) participated. Univariate and multivariate growth curve analyses showed that support declined from early to middle adolescence for boys and girls and increased from middle to late adolescence for girls, while stabilizing for boys. Conflict was found to temporarily increase during middle adolescence. Parental power (relative power and dominance of parents) decreased from early to late adolescence. Results indicated that: (1) parent–adolescent relationships become more egalitarian during adolescence, (2) parents perceived by adolescents as powerful are viewed as supportive, especially in early adolescence, and (3) perceived conflict with parents is related to but not an impetus for changes in parent–adolescent relationships towards more equality.

Developmental links of adolescent disclosure, parental solicitation, and control with delinquency: moderation by parental support.

This 4-wave study among 309 Dutch adolescents and their parents examined changes in adolescent disclosure, parental solicitation, and parental control and their links with the development of delinquent activities. Annually, adolescents and both parents reported on adolescent disclosure, parental solicitation, and parental control, and adolescents reported on delinquent activities and parental support. Latent growth curve analyses revealed a linear decline in parental control between ages 13 and 16. Adolescent disclosure decreased gradually in adolescent reports and showed an L-shaped pattern in father reports and a V-shaped pattern in mother reports. A stronger increase in delinquent activities was related to a stronger decrease in disclosure in mother and adolescent reports and to lower levels of disclosure in father reports. The linkages between levels of disclosure and delinquent activities were stronger in families with high parental support than in families with lower support. Furthermore, in lower parental support families, a stronger decrease in paternal control was related to a stronger increase in delinquent activities. In high parental support families, however, a stronger decrease in adolescent-reported parental control was related to a less strong increase in delinquent activities.

Identity Formation in Adolescence: Change or Stability?

The aim of this five-wave longitudinal study of 923 early to middle adolescents (50.7% boys; 49.3% girls) and 390 middle to late adolescents (43.3% boys and 56.7% girls) is to provide a comprehensive view on change and stability in identity formation from ages 12 to 20. Several types of change and stability (i.e., mean-level change, rank-order stability, and profile similarity) were assessed for three dimensions of identity formation (i.e., commitment, in-depth exploration, and reconsideration), using adolescent self-report questionnaires. Results revealed changes in identity dimensions towards maturity, indicated by a decreasing tendency for reconsideration, increasingly more in-depth exploration, and increasingly more stable identity dimension profiles. Mean levels of commitment remained stable, and rank-order stability of commitment, in-depth exploration, and reconsideration did not change with age. Overall, girls were more mature with regard to identity formation in early adolescence, but boys had caught up with them by late adolescence. Taken together, our findings indicate that adolescent identity formation is guided by progressive changes in the way adolescents deal with commitments, rather than by changes in the commitments themselves.

Longitudinal Associations between Perceived Parent-Child Relationship Quality and Depressive Symptoms in Adolescence.

This longitudinal study examined bidirectional paths between perceived parent-adolescent relationship quality and depressive symptoms, as well as the moderating role of sex, age, and personality type. 1313 Dutch adolescents (51% girls) from two cohorts (923 12-year olds and 390 16-year olds at Wave 1) reported on their personality, depressive symptoms, and perceived relationship quality to parents in four waves. Consistent with a relationship erosion perspective, depressive symptoms negatively predicted perceived relationship quality with parents. Relationship quality to mothers predicted depressive symptoms for boys and girls, but relationship quality to fathers predicted depressive symptoms only for boys. Personality type only moderated initial associations between relationship quality with mothers and depressive symptoms, which were stronger for Overcontrollers and Undercontrollers than for Resilients. Results thus reveal a pattern of mutual influence between perceived relationship quality and depressive symptoms that is moderated by the interplay among parent and adolescent sex and adolescent personality type.

The role of music preferences in early adolescents' friendship formation and stability.

The present study examines the role of similarity in music preferences in the formation and discontinuation of friendships over a 1-year period. Questionnaire data were gathered from 283 Dutch same-sex mutual best friends (mean age=12.97) in two waves with a 1-year interval. Results show consistent evidence for high similarity in specific music dimensions among friends at both waves. Moderate similarity was found in the overall patterning of preferences for music genres at both waves, even after controlling for similarity in social background. Specific music similarity in more non-mainstream music dimensions and overall music similarity at Wave 1 were related to selecting a new friend at Wave 2. However, similarity in music preferences was not related to the discontinuation of an existing friendship at Wave 2. Thus, results suggest that similarity in music preferences is related to friendship formation, and not to friendship discontinuation.

What parents don't know and how it may affect their children: qualifying the disclosure-adjustment link.

Recent research has identified adolescent disclosure to parents as a powerful predictor of adolescent adjustment. We propose, however, that the common operationalization of adolescent disclosure incorporates the two separate constructs of disclosure and secrecy, and predicted that the disclosure-adjustment link can largely be explained by the unique contribution of secrecy from parents. A four-wave survey study among 309 adolescents tested these predictions. Factor analyses confirmed that disclosure and secrecy should be distinguished as two separate constructs. Moreover, in cross-lagged path analyses, only secrecy was a longitudinal predictor of adolescent internalizing (i.e., depression) and externalizing (i.e., delinquency) problems, disclosure was not. Secrecy consistently contributed to the longitudinal prediction of delinquency from early to middle adolescence, whereas it contributed to the prediction of depression only in early adolescence. Findings thus attest the importance of distinguishing between disclosure and secrecy and suggest that the disclosure-adjustment link may actually reflect a secrecy-maladjustment link.

Personality Types in Adolescence: Change and stability and Links With Adjustment and Relationships : A Five-Wave Longitudinal Study.

We examined change and stability of the 3 personality types identified by Block and Block (1980) and studied their links with adjustment and relationships. We used data from a 5-wave study of 923 early-to-middle and 390 middle-to-late adolescents, thereby covering the ages of 12-20 years. In Study 1, systematic evidence for personality change was found, in that the number of overcontrollers and undercontrollers decreased, whereas the number of resilients increased. Undercontrol, in particular, was found to peak in early-to-middle adolescence. We also found substantial stability of personality types, because 73.5% of the adolescents had the same personality type across the 5 waves. Personality change was mainly characterized by 2 transitions: overcontrol → resiliency and undercontrol → resiliency. The transitional analyses implied that the resilient type serves more often as the end point of personality development in adolescence than do overcontrol and undercontrol. Analyses of the personality type trajectories also revealed that the majority of adolescents who change personality type across 5 years made only 1 transition. Study 2 revealed systematic differences between resilients and overcontrollers in anxiety. Stable resilients were less anxious over time than were stable overcontrollers. Further, change from overcontrol to the resilient type was accompanied by decreases in anxiety, whereas change from the resilient type to overcontrol was accompanied by an increase in anxiety. Similarly, systematic differences between personality types were found in the formation of intimate relationships.
