Brief report: personality correlates of susceptibility to peer influence in adolescence

Positive Emotion Dysregulation and Social Impairments in Adolescents with and without ADHD

Although research suggests that emotion dysregulation may underlie adolescents' social impairments, studies have focused almost exclusively on the dysregulation of negative emotions. The present study addressed this gap in the literature by examining whether behavioral manifestations of positive emotion dysregulation are also implicated. A sample of 13-18-year-old adolescents (56.8% female) with and without a childhood diagnosis of attention-deficit/hyperactivity disorder (ADHD) was used, increasing variability in impairment profiles. Adolescents self-reported behavioral difficulties related to positive emotion dysregulation (i.e., impulse control difficulties, difficulties engaging in goal-directed behavior, and non-acceptance of positive emotions), negative emotion dysregulation, and social impairments (i.e., peer rejection, friendship quality, deviant peer affiliation, aggression, and victimization); parents rated adolescent's ADHD symptoms. Regression analyses indicated that impulse control difficulties when experiencing positive emotions uniquely predicted greater conflict in the best friend relationship, deviant peer affiliation, aggression, and victimization, even when accounting for negative emotion dysregulation and current ADHD symptoms. The significant effect of impulse control difficulties on these social impairments was consistent when accounting for oppositional defiant disorder and depression symptoms and when examining the main predictors only in adolescents with childhood or adolescent clinical elevations in ADHD symptoms. These results are the first to indicate that even for adolescents with ADHD, positive emotion dysregulation, and specifically impulse control difficulties, may significantly predict social challenges.

Peer Pressure and SNS Addiction in Adolescents: The Mediating Role of SNS-Use Motives

The present research was carried out to clarify relationships between peer pressure, social networking site (SNS) addiction, and SNS-use motives in Korean adolescents. Adolescent SNS users ( N = 300, 52.70% female) completed self-report measures of peer pressure, SNS addiction, and SNS-use motives. Findings indicated that adolescents reporting more peer pressure had higher levels of SNS addiction. Moreover, the relationship between peer pressure and SNS addiction was mediated by coping and social-conformity use motives. Results are discussed in terms of implications for prevention and intervention, for adolescents facing peer pressure.

Formal Modeling of the Resistance to Peer Influence Questionnaire: A Comparison of Adolescent Boys and Girls With and Without Mild-to-Borderline Intellectual Disability

Items of the Resistance to Peer Influence Questionnaire (RPIQ) have a tree-based structure. On each item, individuals first choose whether a less versus more peer-resistant group best describes them; they then indicate whether it is "Really true" versus "Sort of true" that they belong to the chosen group. Using tree-based item response theory, we show that RPIQ items tap three dimensions: A Resistance to Peer Influence (RPI) dimension and two Response Polarization dimensions. We then reveal subgroup differences on these dimensions. That is, adolescents with mild-to-borderline intellectual disability, compared with typically developing adolescents, are less RPI and more polarized in their responses. Also, girls, compared with boys, are more RPI, and, when high RPI, more polarized in their responses. Together, these results indicate that a tree-based modeling approach yields a more sensitive measure of individuals' RPI as well as their tendency to respond more or less extremely.

Longitudinal Associations between Delinquent Behaviour of Friends and Delinquent Behaviour of Adolescents: Moderation by Adolescent Personality Traits

In this longitudinal study, we examined whether personality traits (parent–rated Big Five personality traits) render some adolescents more susceptible than others to delinquent behaviour of friends, predicting rank–order changes in adolescents‘ self–reported delinquent behaviour. We examine susceptibility to both perceived (reported by adolescents) and self–reported (reported by friends) delinquent behaviour of friends. Participants in this two–wave study were 285 Dutch adolescents and their best friends. The adolescents (50% girls) were 15.5 years old on average (SD = 0.8 years), and their best friends (N = 176; 58% girls) were 15.1 years old (SD = 1.5 years). Perceived (but not self–reported) delinquency of friends predicted a stronger increase in adolescent delinquency 1 year later, especially among adolescents low or average on conscientiousness. Emotional stability, agreeableness, extraversion and openness did not moderate associations between delinquency of friends and delinquency of adolescents. Our findings show that low conscientiousness serves as a risk factor, increasing vulnerability to perceived delinquent behaviour of friends, while high conscientiousness serves as a protective factor, increasing resilience to perceived delinquent behaviour of friends. Our findings also show that adolescents are susceptible to, and differ in susceptibility to, friends‘ delinquent behaviour as they perceive it—not to delinquent behaviour as reported by friends themselves.

Brain structure correlates of emotion-based rash impulsivity

Negative urgency (the tendency to engage in rash, ill-considered action in response to intense negative emotions), is a personality trait that has been linked to problematic involvement in several risky and impulsive behaviours, and to various forms of disinhibitory psychopathology, but its neurobiological correlates are poorly understood. Here, we explored whether inter-individual variation in levels of trait negative urgency was associated with inter-individual variation in regional grey matter volumes. Using voxel-based morphometry (VBM) in a sample (n=152) of healthy participants, we found that smaller volumes of the dorsomedial prefrontal cortex and right temporal pole, regions previously linked to emotion appraisal, emotion regulation and emotion-based decision-making, were associated with higher levels of trait negative urgency. When controlling for other impulsivity linked personality traits (sensation seeking, lack of planning/perseverance) and negative emotionality per se (neuroticism), these associations remained, and an additional relationship was found between higher levels of trait negative urgency and smaller volumes of the left ventral striatum. This latter finding mirrors recent VBM findings in an animal model of impulsivity. Our findings offer novel insight into the brain structure correlates of one key source of inter-individual differences in impulsivity.

Adolescent socio-economic and school-based social status, health and well-being

Studies of adults and adolescents suggest subjective socio-economic status (SES) is associated with health/well-being even after adjustment for objective SES. In adolescence, objective SES may have weaker relationships with health/well-being than at other life stages; school-based social status may be of greater relevance. We investigated the associations which objective SES (residential deprivation and family affluence), subjective SES and three school-based subjective social status dimensions (“SSS-peer”, “SSS-scholastic” and “SSS-sports”) had with physical symptoms, psychological distress and anger among 2503 Scottish 13–15 year-olds. Associations between objective SES and health/well-being were weak and inconsistent. Lower subjective SES was associated with increased physical symptoms and psychological distress, lower SSS-peer with increased psychological distress but reduced anger, lower SSS-scholastic with increased physical symptoms, psychological distress and anger, and lower SSS-sports with increased physical symptoms and psychological distress. Associations did not differ by gender. Objective and subjective SES had weaker associations with health/well-being than did school-based SSS dimensions. These findings underline the importance of school-based SSS in adolescence, and the need for future studies to include a range of school-based SSS dimensions and several health/well-being measures. They also highlight the need for a focus on school-based social status among those working to promote adolescent health/well-being.

•

We examined associations between adolescent social status and several health measures.

•

Models included objective and subjective socio-economic status and school peer, scholastic and sports status.

•

School status had stronger associations with health than did socio-economic status.

•

Different school status dimensions and health measures were associated in different ways.

•

Studies should include a range of school status dimensions and health measures.
