The unfolding dark side:Age trends in dark personality features

Age and gender differences across the lifespan in dark personality features could provide hints regarding these features’ functions. We measured manipulation, callous affect, and egocentricity using the Dirty Dozen and their links with agreeableness in a pooled cross-sectional dataset (N = 4292) and a longitudinal dataset (N = 325). Age trends for all dark personality features were progressive through adolescence, but negative through adulthood. Men scored higher than women, but the gender gap varied with age. Trends for agreeableness partly mirrored these trends and changes in dark personality features and agreeableness were correlated. Results are discussed in light of the maturity principle of personality, gender role socialization processes, and issues regarding incremental validity of dark personality over traditional antagonism measures

Personality and anxiety associations in adolescents and emerging adults

This study was aimed at unraveling associations between Big Five personality traits and anxiety symptoms of panic, generalized anxiety disorder, school phobia, separation anxiety, and social phobia in male and female adolescents and emerging adults from the general population. Participants were 3,758 (54.6% females) adolescents and emerging adults aged between 11 and 26 years. They completed the shortened Big Five questionnaire and the Screen for Child Anxiety Related Emotional Disorders. Results indicated that the associations between Big Five and anxiety symptoms were consistent across gender and age groups. Most of the associations were statistically significant with the strongest links found between extraversion and symptoms of social phobia; conscientiousness and symptoms of school anxiety; and emotional stability and symptoms of panic, separation, generalized, and school anxiety. All these associations were negative, suggesting that higher levels of these personality traits were related to lower levels of 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

The dynamics of personality and identity in adolescence

The present paper summarizes some of the key findings on the dynamics of personality and identity in adolescence by the author's research group. With regard to personality, we found evidence for a maturation process in which girls were ahead of boys. Being ahead or lagging behind with regard to this maturation process was found to be associated with internalizing and externalizing problems, respectively. We further identified which specific traits were associated with problem behaviour, and showed that these associations are bidirectional. With regard to identity, we showed that short-term fluctuations affect subsequent levels of identity dimensions. In addition, we uncovered a commitment–reconsideration dynamic that operates on a day-to-day level. Keywords: Adolescence, Personality, Identity formation, Big Five, Adjustmen

Loneliness and Facebook motives in adolescence:A longitudinal inquiry into directionality of effect

The increasing popularity of Facebook among adolescents has stimulated research to investigate the relationship between Facebook use and loneliness, which is particularly prevalent in adolescence. The aim of the present study was to improve our understanding of the relationship between Facebook use and loneliness. Specifically, we examined how Facebook motives and two relationship-specific forms of adolescent loneliness are associated longitudinally. Cross-lagged analysis based on data from 256 adolescents (64% girls, Mage = 15.88 years) revealed that peer-related loneliness was related over time to using Facebook for social skills compensation, reducing feelings of loneliness, and having interpersonal contact. Facebook use for making new friends reduced peer-related loneliness over time, whereas Facebook use for social skills compensation increased peer-related loneliness over time. Hence, depending on adolescents' Facebook motives, either the displacement or the stimulation hypothesis is supported. Implications and suggestions for future research are discussed.

Is the Generalized Anxiety Disorder Symptom of Worry Just Another Form of Neuroticism? A 5-Year Longitudinal Study of Adolescents From the General Population

Objective: Generalized anxiety disorder (GAD) is a commonly occurring anxiety disorder that many times is characterized by an onset in adolescence and symptoms that increase in severity Into adulthood Due to the persistent nature of the disorder's primary symptom of worry, which appears more related to a personality trait than an anxiety state, the current DSM-IV nosology of GAD has been debated. Recently, evidence is accumulating that suggests that the GAD symptom of worry is strongly related to the personality trait of neuroticism. This study investigates whether the GAD symptom of worry and neuroticism are best explained as 1 general factor or as 2 distinct entities in adolescents. Additionally, the Interrelation over time between the GAD symptom of worry and neuroticism in adolescents is examined. Method: Dutch secondary school adolescents from the general community were prospectively studied annually for 5 years. The adolescent population consisted of 923 early adolescents (49% girls) and 390 middle adolescents (57% girls), with mean ages of 12 and 16 years, respectively, on the first measurement wave. At all 5 waves, the adolescents completed self-rated measures of GAD and neurotic symptoms. Results: Confirmatory factor analyses established that the GAD symptom of worry and neuroticism are 2 distinct entities, and structural equation modeling demonstrated very strong interrelated properties between these 2 entitles These findings did not differ between the adolescent sex and age groups Conclusions: The findings suggest that the GAD symptom of worry is more akin to a personality trait than an anxiety state in adolescents, which may hold implications for the current nosology and treatment of GAD.

Personality and externalizing behavior in the transition to young adulthood: The additive value of personality facets

PURPOSE: The directionality of effects in the associations between personality and externalizing behavior (i.e., delinquency, soft drugs use, and alcohol abuse) is unclear. Moreover, previous studies only examined personality trait domains when examining these associations, whereas personality facets underlying these broad domains provide more specificity. To address these limitations, the present study examined the directionality of effects between externalizing behavior and personality while employing a facet-level approach to personality. METHODS: Cross-lagged panel models were employed to four annual measurement waves of longitudinal data on 485 Belgian-Caucasian late adolescents (87.4 % female; M age = 18.63 years, SD = 0.61). Participants filled out the NEO-FFI as a measure of personality, the Deviant Behavior Scale as a measure of delinquency, and single items for soft drugs use and alcohol abuse on all four measurement occasions. RESULTS: The incremental value of personality facets over broad trait domains was demonstrated, as it was often the case that only some, but not all, facets underlying a specific trait domain were significantly associated with specific externalizing behaviors. Furthermore, linkages between personality and externalizing behavior were shown to be complex. Depending on the personality trait domain or facet and the specific behavior under investigation, the directionality of effects may differ. CONCLUSIONS: To capture the full complexity of the linkages between personality and externalizing behavior, a facet approach to personality is recommended. This information is potentially important for clinicians, as it indicates which specific aspects of a broad trait domain affect, and are affected by, specific externalizing behaviors.status: publishe
