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.

Psychometric Properties of the Screen for Child Anxiety Related Emotional Disorders (SCARED) in the General Adolescent Population

OBJECTIVE This study examined the psychometric properties of the Screen for Child Anxiety Related Emotional Disorders (SCARED) in a large sample of adolescents from the general population. METHOD In 2001, 1,340 junior high and high school adolescents in the Netherlands completed the SCARED. The SCARED is a questionnaire that purports to measure five child and adolescent anxiety symptom dimensions. The factor structure of the SCARED was investigated by means of confirmatory factor analyses that were conducted for males and females, early (10-13 years) and middle (14-18 years) adolescent groups, and for Dutch and ethnic minorities. Analyses of variance were carried out to compare mean scores for the various groups. RESULTS The five-factor structure of the SCARED not only had the best fit for the general adolescent population but also for the age, gender, and ethnic groups. It was also found that the SCARED scores of the adolescent subgroups differed from one another in agreement with previous studies on adolescent anxiety disorder symptoms. CONCLUSIONS The findings of this study support the claim that the SCARED has a five-factor structure. The usefulness of the SCARED was also demonstrated.

Conceptual Analysis and Measurement of Adolescent Autonomy

The aim of the present study was to examine the concept of adolescent autonomy. A conceptual analysis of different theoretical perspectives has resulted in an integrative model of attitudinal, emotional, and functional autonomy. Attitudinal autonomy refers to the cognitive process of choosing and defining a goal. Emotional autonomy refers to the affective process of feeling confident about ones own choices and goals. Functional autonomy refers to the regulatory process of developing a strategy to achieve these goals. The empirical value of this model was tested by developing a questionnaire assessing adolescent autonomy. Subjects were 400 adolescents between 12 and 18 years old. Confirmatory factor analyses (LISREL 8) provided evidence for the 3 hypothesized dimensions.

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.

Developmental trajectories of adolescent anxiety disorder symptoms: a 5-year prospective community study.

OBJECTIVE This study prospectively examined the developmental trajectories of anxiety disorder symptoms in a large sample of adolescents from the general population. METHOD Two cohorts of early and middle adolescents (1,318 junior high and high school students) completed the Screen for Child Anxiety Related Emotional Disorders during 5 consecutive years. The Screen for Child Anxiety Related Emotional Disorders is a questionnaire that measures self-rated child and adolescent anxiety symptoms that map onto DSM-IV-TR anxiety disorders. At the first wave of measurement, the early and middle adolescent cohorts were an average of 12 and 16 years of age, respectively. Age and sex differences in the developmental trajectories of adolescent anxiety disorder symptoms over time were examined by means of latent growth modeling. RESULTS Over the course of 5 years, there was a slight decrease in the panic disorder, school anxiety, and separation anxiety disorder symptoms for all of the adolescents, with the exception of social phobia symptoms, which remained fairly stable over time. Adolescent girls showed a slight increase of generalized anxiety disorder symptoms over time, whereas these symptoms decreased among adolescent boys. CONCLUSIONS This study replicates and extends earlier findings on the developmental trajectories of anxiety symptoms during adolescence. By using individually focused, trajectory-based analyses rather than group score differences, this study extends earlier findings and advances our understanding of age and sex differences in the development of adolescent anxiety symptoms.

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.

Developmental Patterns in Adolescent Attachment to Mother, Father and Sibling

The aim of this study was to examine the development of quality of attachment of adolescents to their parents and siblings during adolescence and the role that gender differences play in this development, using latent growth curve analysis. In 288 families, adolescents reported on their attachment relationships with their parents and siblings. Quality of attachment changes during adolescence, and these changes are influenced by both gender of the adolescent and gender of the attachment figure. Results showed that change in mean level of quality of attachment to mother appeared to be nonlinear for boys, whereas mean level of attachment of adolescent girls to their mothers showed a linear decline. Results for attachment to father were opposite, with a linear decline in quality for boys, and a nonlinear development for girls. Quality of attachment to sibling showed differential development depending on gender composition of the sibling dyad.
