Early Adolescent Friendship Selection Based on Externalizing Behavior: the Moderating Role of Pubertal Development. The SNARE Study

Abstract This study examined friendship (de-)selection processes in early adolescence. Pubertal development was examined as a potential moderator. It was expected that pubertal development would be associated with an increased tendency for adolescents to select their friends based on their similarities in externalizing behavior engagement (i.e., delinquency, alcohol use, and tobacco use). Data were used from the first three waves of the SNARE (Social Network Analysis of Risk behavior in Early adolescence) study (N = 1144; 50 % boys; M age = 12.7; SD = 0.47), including students who entered the first year of secondary school. The hypothesis was tested using Stochastic Actor-Based Modeling in SIENA. While taking the network structure into account, and controlling for peer influence effects, the results supported this hypothesis. Early adolescents with higher pubertal development were as likely as their peers to select friends based on similarity in externalizing behavior and especially likely to remain friends with peers who had a similar level of externalizing behavior, and thus break friendship ties with dissimilar friends in this respect. As early adolescents are actively engaged in reorganizing their social context, adolescents with a higher pubertal development are especially likely to lose friendships with peers who do not engage in externalizing behavior, thus losing an important source of adaptive social control (i.e., friends who do not engage in externalizing behavior)

Low implicit and explicit aversion toward self-cutting stimuli longitudinally predict nonsuicidal self-injury.

There is a pressing need to improve the ability to identify individuals at risk for nonsuicidal self-injury (NSSI; e.g., cutting or burning oneself); unfortunately, beyond prior NSSI, there are few powerful longitudinal predictors of NSSI. The present study addressed this limitation by investigating the ability of a novel factor—low aversion to self-cutting stimuli—to longitudinally predict NSSI in 49 individuals with a history of self-cutting. Results revealed that both low implicit and explicit aversion to self-cutting stimuli were significantly associated with future NSSI (rs = .32–.51), and that these associations were unique from several other theoretically important predictors, including prior NSSI, number of NSSI methods, implicit identification with self-cutting, self-prediction of future NSSI, emotion dysregulation, and therapy status. These findings are consistent with the notion that instinctive barriers (e.g., aversion to NSSI stimuli, pain) dissuade most people from engaging in NSSI, and that the erosion of these barriers may facilitate NSSI

ProjectHeartforGirls.com: Development of a Web-Based HIV/STD Prevention Program for Adolescent Girls Emphasizing Sexual Communication Skills

This article describes the development of ProjectHeartforGirls.com, an interactive web-based program designed to improve sexual communication skills and reduce the risk of HIV/STDs among adolescent girls, a population at heightened risk for negative sexual health outcomes (CDC, 2013). Although sexual communication is a critical predictor of safer sex among teens, there are few online interventions that target these skills as a central program component. We developed ProjectHeartforGirls.com to fill this gap. Program development involved 1) identifying the target population (ethnically-diverse high school girls); 2) clarifying the theoretical foundation (Reasoned Action Model); 3) conducting formative qualitative research (n=25 girls); 4) drafting initial program content; 5) receiving ongoing feedback from a teen advisory board (n=5 girls); 6) programming online content; and 7) conducting usability testing (n=6 girls). These steps are described along with the final intervention product, which is currently being evaluated in a randomized controlled trial

Social skill and social cognition in adolescents at genetic risk for psychosis

Adolescents at genetic high risk (GHR) for schizophrenia have shown social skill impairments and there is some evidence to suggest they have Theory of Mind (ToM) deficits; however no research has used a standardized, performance-based behavioral measure to assess social functioning in this population nor evaluated ToM with a well-validated measure. We evaluated the psychometric properties of a new, theoretically-derived assessment of social functioning in GHR adolescents: the "High-Risk Social Challenge" task (HiSoC). The second aim was to explore whether GHR adolescents would show social skill and ToM deficits as compared to a nonpsychiatric control (NPC) group. The present study evaluated social functioning with the HiSoC and ToM with the Eyes Test in 23 GHR adolescents and 31 NPCs. The HiSoC demonstrated high levels of reliability and validity. The GHR adolescents showed social skill impairments, but not ToM deficits. The results suggest that the HiSoC is a potentially useful new measure of social functioning in GHR adolescents. Furthermore, the findings add to the current body of literature that indicates that social skill impairments are related to schizophrenia vulnerability

Children’s Postdisaster Trajectories of PTS Symptoms: Predicting Chronic Distress

There are no studies of the distinct trajectories of children’s psychological distress over the first year after a destructive natural disaster and the determinants of these trajectories

Psychological, peer, and family influences on smoking among an adolescent psychiatric sample

While much is known about adolescent cigarette use and initiation in community samples, less is known about these factors among adolescents in clinic-referred populations or those with severe psychopathology. Data were collected from 106 adolescents aged 12 to 15 years (M = 13.6; SD = .74) recruited from a psychiatric inpatient facility. Hierarchical logistic regressions assessed the relationship between psychological, peer, and family environment factors and smoking at baseline and 18 months post-hospitalization. Conduct problem symptoms, friends’ cigarette use, and friends’ marijuana use were associated with greater odds of lifetime and current smoking at baseline, but not at follow-up. After accounting for the significant effect of baseline use, greater family conflict predicted decreased odds of having initiated smoking at the 18 month follow-up. The period following inpatient psychiatric hospitalization may represent an important window for smoking cessation and prevention efforts targeting peer and family factors, especially for youth with externalizing problems

Negative Life Events and Non-Suicidal Self-Injury in an Adolescent Inpatient Sample

Although life stressors have been implicated in the aetiology of various forms of psychopathology related to non-suicidal self-injury (NSSI), particularly depression and suicidal behavior, they have rarely been examined in relation with NSSI. The objective of the current study was to assess the association between life stressors and NSSI in adolescent inpatients

Childhood loneliness as a predictor of adolescent depressive symptoms: an 8-year longitudinal study

Childhood loneliness is characterised by children’s perceived dissatisfaction with aspects of their social relationships. This 8-year prospective study investigates whether loneliness in childhood predicts depressive symptoms in adolescence, controlling for early childhood indicators of emotional problems and a sociometric measure of peer social preference. 296 children were tested in the infant years of primary school (T1 5 years of age), in the upper primary school (T2 9 years of age) and in secondary school (T3 13 years of age). At T1, children completed the loneliness assessment and sociometric interview. Their teachers completed externalisation and internalisation rating scales for each child. At T2, children completed a loneliness assessment, a measure of depressive symptoms, and the sociometric interview. At T3, children completed the depressive symptom assessment. An SEM analysis showed that depressive symptoms in early adolescence (age 13) were predicted by reports of depressive symptoms at age 8, which were themselves predicted by internalisation in the infant school (5 years). The interactive effect of loneliness at 5 and 9, indicative of prolonged loneliness in childhood, also predicted depressive symptoms at age 13. Parent and peer-related loneliness at age 5 and 9, peer acceptance variables, and duration of parent loneliness did not predict depression. Our results suggest that enduring peer-related loneliness during childhood constitutes an interpersonal stressor that predisposes children to adolescent depressive symptoms. Possible mediators are discussed

Temporal relationship between substance use and delinquent behavior among young psychiatrically hospitalized adolescents

There is considerable evidence linking substance use and delinquent behavior among adolescents. However, the nature and temporal ordering of this relationship remains uncertain, particularly among early adolescents and those with significant psychopathology. This study examined the temporal ordering of substance use and delinquent behavior in a sample of psychiatrically hospitalized early adolescents. Youth (n = 108) between the ages of 12 and 15 years completed three assessments over 18 months following hospitalization. Separate cross-lagged panel models examined the reciprocal relationship between delinquent behavior and two types of substance use (e.g., alcohol and marijuana). Results provided evidence of cross-lagged effects for marijuana: delinquent behavior at 9 months predicted marijuana use at 18 months. No predictive effects were found between alcohol use and delinquent behavior over time. Findings demonstrate the stability of delinquent behavior and substance use among young adolescents with psychiatric concerns. Furthermore, results highlight the value of examining alcohol and marijuana use outcomes separately in order to better understand the complex pathways between substance use and delinquent behavior among early adolescents
