Prior research has shown cognitive reactivity to be a diathesis for depression. Seeking evidence for the developmental origins of such diatheses, the current study examined peer victimization and harsh parenting as developmental correlates of cognitive reactivity in 571 children and adolescents (ages 8–13 years). Four major findings emerged. First, a new method for assessing cognitive reactivity in children and adolescents showed significant reliability and demonstrated construct validity vis-à-vis its relation to depression. Second, history of more severe peer victimization was significantly related to cognitive reactivity, with verbal victimization being more strongly tied to cognitive reactivity than other subtypes of peer victimization. Third, harsh parenting was also significantly related to cognitive reactivity. Fourth, both peer victimization and harsh parenting made unique statistical contributions to cognitive reactivity, after controlling for the effects of the other. Taken together, these findings provide preliminary support for a developmental model pertaining to origins of cognitive reactivity in children and adolescents.

Obsessive compulsive and related disorders have been linked to sleep disturbances. Given that adolescence is a core risk period for body dysmorphic disorder (BDD), and sleep difficulties are particularly prevalent during adolescence, the current study aims to examine associations between sleep quality and BDD symptoms among two separate samples of adolescents. It was hypothesized that lower reported sleep quality would be associated with higher reported BDD symptoms, even after controlling for anxiety and depression. Study 1 included 325 adolescents aged 11–18 years who completed an online survey via social media recruitment. The survey included questionnaires on BDD symptoms, sleep quality, and anxiety and depressive disorder symptoms. Study 2 included 396 adolescents who completed the same online survey. In study 1, a significant omnibus regression model accounted for 20.0% of the variance in adolescent BDD symptoms. After controlling for anxiety and depressive symptoms, adolescent sleep quality was significantly associated with BDD symptoms, with a small effect size (sr² = 0.02). Study 2 yielded similar results, with a significant omnibus regression model accounting for 26.5% of the variance in adolescent BDD symptoms, and significant associations between adolescent sleep quality and BDD symptoms yielding a small effect size (sr² = 0.01). Exploratory analyses in both studies demonstrated associations between difficulty returning to wakefulness and BDD symptoms. Adolescent sleep quality and BDD symptoms were linked, such that adolescents who reported lower quality sleep also reported higher levels of BDD symptoms. Future research can aim to replicate and extend these results using more rigorous (e.g., longitudinal, experimental) methods.

Although current cognitive-behavioral models have highlighted a central role of dysfunctional “obsessive beliefs” about threat, responsibility, uncertainty, perfectionism, importance and control of thoughts in the development of obsessive-compulsive disorder (OCD), empirical evidence in support of this notion has been inconsistent. The present investigation further examines the association between obsessive beliefs and OCD symptoms among nonclinical (Study 1) and clinical samples (Study 2). Findings from Study 1 (n = 368) demonstrated that OCD symptom dimensions are associated with some form of obsessive belief (generality). Although findings from Study 1 revealed that different obsessive beliefs related to different OCD symptom dimensions in a meaningful way (congruence), findings from Study 2 failed to support the hypothesis that OCD patients (n = 30) would endorse obsessive beliefs more strongly than patients (n = 30) with generalized anxiety disorder (specificity). However, both patient groups endorsed obsessive beliefs more strongly than non-clinical controls (n = 30). Implications of these findings for conceptualizing the relationship between obsessive beliefs and specific dimensions of OCD are discussed.

The prevalence of mental health problems, including suicidal thoughts and behavior, increase during adolescence. In fact, suicide is the second leading cause of death among adolescents, with a prevalence of 4.04 per 100,000. The prevalence of suicidal ideation and suicide attempts is even greater, with up to 17% of adolescents reporting having seriously considered attempting suicide and 8% having made a suicide attempt at least once in the past year. The current study focuses on advancing our understanding of how social support may influence links between psychopathology and suicidal thoughts and behaviors.

Cohen and Wills (Cohen, S., & Wills, T. A., 1985, Stress, social support, and the buffering hypothesis. Psychological Bulletin, 98, 310–357) described two broad models whereby social support could mitigate the deleterious effects of stress on health: a main effect model and stress-buffering model. A specific application of these models was tested in a three-wave, multimethod study of 1888 children to assess ways parental support (social support) mitigates the effects of peer victimization (stress) on children’s depressive symptoms and depression-related cognitions (health-related outcomes). Results revealed that (a) both supportive parenting and peer victimization had main effects on depressive symptoms and cognitions; (b) supportive parenting and peer victimization did not interact in the prediction of depressive thoughts and symptoms; (c) these results generalized across age and gender; and (d) increases in depressive symptoms were related to later reduction of supportive parenting and later increase in peer victimization. Although supportive parenting did not moderate the adverse outcomes associated with peer victimization, results show that its main effect can counterbalance or offset these effects to some degree. Implications for practice and future research are discussed. (PsycInfo Database Record (c) 2025 APA, all rights reserved)

Social anxiety is the most common anxiety disorder among youth; theoretical and empirical work suggest specific parenting behaviors may be relevant. However, findings are inconsistent, particularly in terms of maternal as compared to paternal effects. In the current study, we evaluated the indirect effects of perceived psychological control on the relation between anxious rearing behaviors and child social anxiety among 112 community-recruited girls (ages 12–15 years). In addition to self-report, adolescent participants completed a laboratory-based social stress task. In line with hypotheses, results indicated indirect effects of psychological control on the relation between anxious rearing behaviors and child social anxiety in maternal but not paternal models. Findings are discussed in terms of their theoretical and empirical implications for clarifying the role of parental relations in adolescent social anxiety.
