The Changing Nature of Adolescent Friendships Longitudinal Links With Early Adolescent Ego Development

Although success in managing evolving peer relationships is linked to critical adolescent outcomes, little is known about the specific factors that lead to success or failure in peer relationship development across adolescence. This longitudinal study examines the role of adolescents' level of ego development as a predictor of the future course of several facets of friendship development in early adolescence. Ego development was assessed in a community sample of adolescents at age 13. Several facets of adolescent friendship were also assessed at 13 and then reassessed 1 year later, including adolescent intimate behavior during a supportive interaction with their best friends, adolescent reports of psychological security in their friendships, and peer-rated popularity. As predicted, ego development not only explained concurrent levels of peer functioning but also predicted markers of change over time in each of the assessed domains of peer functioning. Implications for ego development in increasing our understanding of individual differences in adolescent friendship development are discussed.     

Parentification and mental health symptoms: mediator effects of perceived unfairness and differentiation of self

Existing research indicates that parentification can result in positive and negative outcomes for individuals; however, little is known about the mechanisms that account for the variability. This study tested a theoretical model of the relation between parentification tasks and mental health symptoms, with perceived unfairness and differentiation of self (DoS) as mediators. The results supported the proposed model in a sample of 783 college students. A significant total indirect effect existed between the latent construct of parentification and that of mental health symptoms. Significant specific indirect effects were observed between parentification and mental health symptoms with perceived unfairness as a mediator; between parentification and DoS with perceived unfairness as a mediator and between perceived unfairness and mental health symptoms mediated by DoS. Implications for clinical work with adult clients who have experienced parentification in their family of origin are addressed.     

Subjective and physiological responses to the 35% carbon dioxide challenge in healthy and non-clinical control populations: a meta-analysis and systematic review

Background/Rationale: The carbon dioxide (CO₂) challenge has been reliably used in laboratory settings as a panicogen in clinical populations. However, the magnitude of these effects on healthy and non-clinical control populations are not clear. The aim of this meta-analysis and systematic review is to provide quantitative estimates of those effects. Specifically, the current paper will evaluate the relative efficacy of the CO₂ challenge in eliciting both subjective and physiological arousal in healthy and non-clinical control populations.

Method: A total of 16 articles with 35 independent samples were included in the meta-analysis, while 37 studies with 74 independent samples were included in the systematic review.

Results: Both the meta-analysis and systematic review found the CO₂ challenge to elicit an increase in subjective distress via self-reported anxiety and fear. Physiological responses via blood pressure and heart rate were heterogeneous in studies sampled, with no significant changes observed across studies. Moderator analyses revealed the variations in findings may be attributed to participant screening and invasive sampling.

Discussion: Findings highlight the CO₂ challenge as a useful tool in the provocation of subjective distress. Implications for both the use of the CO₂ challenge and its anticipated effects in healthy and non-clinical control populations are discussed.
