The current study examined peer victimization and harsh parenting as longitudinal predictors of broadband and narrowband cognitions associated with the etiology of depression in children and adolescents. The sample consisted of 214 elementary and middle school students. At the start of the study, their average age was 12.2 years (SD = 1.0). The sex ratio was 112 girls to 102 boys. The sample was ethnically diverse (58.9% Caucasian, 34.1% African American, 10.7% Hispanic, 3.3% Asian, and 5.2% other). Children and their parents completed measures of peer victimization and harsh parenting. At two waves 1 year apart, children also completed questionnaire measures of negative and positive broadband cognitive style (e.g., personal failure, global self-worth) and narrowband self-perceptions (e.g., perceived social threat, social acceptance). Every Wave 2 cognitive variable was predicted by peer victimization or harsh parenting or both, even after controlling for a Wave 1 measure of the same cognitive variable. Peer victimization more consistently predicted narrowband social/interpersonal cognitions, whereas harsh parenting more consistently predicted broadband positive and negative cognitions. Furthermore, controlling for positive and negative self-cognitions eliminated a statistically significant effect of harsh parenting and peer victimization on depressive symptoms. Support emerged for the social learning of negative self-cognitions. Support also emerged for negative self-cognitions as a mediator of depressive symptoms. Implications for theory and practice are discussed.

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.

Online social support for young people: Does it recapitulate in-person social support; can it help?

David A. Cole; Elizabeth A. Nick; Rachel L. Zelkowitz; Kathryn Roeder; Tawny Spinelli

As social media websites have grown in popularity, public concern about online victimization has grown as well; however, much less attention has focused on the possible beneficial effects of online social networks. If theory and research about in-person social networks pertain, then online social relationships may represent an important modern source of or vehicle for support. In a study of 231 undergraduates, three major findings emerged: (1) for people with weaker in-person social support, social media sites provide a source of social support that is less redundant of the social support they receive in person; (2) in ways that were not redundant of each other, both online and in-person social support were associated with lower levels of depression-related thoughts and feelings, and (3) the beneficial effects of online social support (like in-person social support) offset some of the adverse effects of peer victimization. The study suggests that augmenting social relations via strategic use of social media can enhance young peoples social support systems in beneficial ways.

ABSTRACT Objective: College students face a significant number of stressors, increasing risk for internalizing and externalizing psychopathology. The current study examines two promising avenues of intervention aimed to reduce stress and prevent psychopathology in this population: a coping skills group and a cognitive training program. Participants: 62 undergraduate students from two universities were recruited from 2013 to 2015. Methods: Students were randomized to a 6-week coping skills group or cognitive training program and completed measures of stress, coping, executive function, and symptoms of anxiety, depression and Attention-Deficit Hyperactivity Disorder (ADHD) at pre- and post-intervention. Results: Participants in both conditions reported significant decreases in social stress, executive function difficulties, and anxiety symptoms post-intervention. Students in the cognitive program improved significantly more on measures of behavior regulation and ADHD symptoms compared to the coping group at post-intervention. Conclusions: Brief stress management interventions targeting coping and executive function may benefit college students at risk for psychopathology.

Impact of homogeneous and heterogeneous parceling strategies when latent variables represent multidimensional constructs.

David A. Cole; Corinne E. Perkins; Rachel L. Zelkowitz

Many researchers are interested in using structural equation models to test theoretical relations among multidimensional constructs; however, logistical constraints often prevent researchers from obtaining multiple measures. The current study examines the implications for such models when a latent variable is extracted from carefully constructed parcels of items obtained from a single multidimensional measure of the multidimensional target construct. Two parceling methods are compared. One is homogeneous parceling, in which items are pooled so that each parcel represents a single lower order dimension of the higher order construct. The other is heterogeneous parceling, in which items are pooled so that each parcel represents all lower order dimensions of the higher order construct. Results of simulated and real data analysis reveal that both approaches can result in models that fit the data well; however, conceptual-theoretical differences exist in the nature of the latent variables that are extracted from homogeneous versus heterogeneous parcels. Additionally, compared with homogeneous parceling, heterogeneous parceling generates smaller (i.e., closer to zero) but tighter estimates of structural path coefficients, the net result of which is greater statistical power to test substantive relations among latent variables. Beyond parceling, implications surface about the nature of latent variables that emerge when the underlying constructs are multidimensional. (PsycINFO Database Record

Time-varying and time-invariant dimensions of depression in children and adolescents: Implications for cross-informant agreement.

The longitudinal structure of depression in children and adolescents was examined by applying a Trait-State-Occasion structural equation model to 4 waves of self, teacher, peer, and parent reports in 2 age groups (9 to 13 and 13 to 16 years old). Analyses revealed that the depression latent variable consisted of 2 longitudinal factors: a time-invariant dimension that was completely stable over time and a time-varying dimension that was not perfectly stable over time. Different sources of information were differentially sensitive to these 2 dimensions. Among adolescents, self- and parent reports better reflected the time-invariant aspects. For children and adolescents, peer and teacher reports better reflected the time-varying aspects. Relatively high cross-informant agreement emerged for the time-invariant dimension in both children and adolescents. Cross-informant agreement for the time-varying dimension was high for adolescents but very low for children. Implications emerge for theoretical models of depression and for its measurement, especially when attempting to predict changes in depression in the context of longitudinal studies.

The Online Social Support Scale: Measure development and validation.

Elizabeth A. Nick; David A. Cole; Sun-Joo Cho; Darcy K. Smith; T. Grace Carter; Rachel L. Zelkowitz

A new measure, the Online Social Support Scale, was developed based on previous theory, research, and measurement of in-person social support. It includes four subscales: Esteem/Emotional Support, Social Companionship, Informational Support, and Instrumental Support. In college and community samples, factor analytic and item response theory results suggest that subtypes of in-person social support also pertain in the online world. Evidence of reliability, convergent validity, and discriminant validity provide excellent psychometric support for the measure. Construct validity accrues to the measure vis-à-vis support for three hypotheses: (a) Various broad types of Internet platforms for social interactions are differentially associated with online social support and online victimization; (b) similar to in-person social support, online social support offsets the adverse effect of negative life events on self-esteem and depression-related outcome; and (c) online social support counteracts the effects of online victimization in much the same way that in-person friends in one social niche counterbalance rejection in other social niches.

The unique associations of self-criticism and shame-proneness to symptoms of disordered eating and depression

Andrew C. Porter; Rachel L. Zelkowitz; David A. Cole

This study examined the unique associations of shame-proneness and self-criticism to symptoms of disordered eating and depression among 186 undergraduate students. The study also tested the degree to which self-criticism and shame-proneness accounted for the association between disordered eating and depressive symptoms. Both shame-proneness and self-criticism were significantly related to disordered eating and depressive symptoms. Self-criticism was significantly associated with disordered eating and depressive symptoms, over-and-above shame-proneness, but the reverse was not true. Controlling for shame-proneness, self-criticism also accounted for a significant proportion of the covariance between disordered eating and depressive symptoms, suggesting that self-criticism could account for some of the comorbidity between depression and eating disorders. Findings suggest that self-criticism may have incremental utility above-and-beyond shame-proneness as part of a transdiagnostic underlying cognitive substrate for depression and disordered eating. Implications emerge for future research and clinical practice.
