The development of depressive attributional style (AS) and its role as a cognitive diathesis for depression were examined in children and adolescents (Grades 2-9). In a 4-wave longitudinal study of 3 overlapping age cohorts, AS, negative life events, and depressive symptoms were evaluated every 12 months. Consistency of children's attributions across situations was moderately high at all ages. The cross-sectional structure of AS changed with age, as stability became a more salient aspect of AS than internality and globality. The structure of AS also changed, becoming more traitlike as children grew older. In longitudinal analyses, evidence of a Cognitive Diathesis x Stress interaction did not emerge until Grades 8 and 9, suggesting that AS may not serve as a diathesis for depression at younger ages. Results suggest that attributional models of depression may require modification before they are applied across developmental levels.

Research on the relation of guilt to psychopathology is highly inconsistent. Some studies suggest that guilt contributes to psychopathology; others suggest that guilt serves a protective role. This review of 23 theory-based definitions of guilt and 25 measures of guilt suggests that a lack of conceptual clarity may be to blame. Measures of guilt do not correspond well to the definitions from which they derive. Many definitions and measures reflect the intrusion of extraneous constructs that could confound guilt research. Furthermore, definitions and measures of guilt change with developmental level. Nevertheless, two broad conceptualizations of guilt emerge. Central to both is a focus on one's action or inactions involving real or imagined moral transgressions. Distinguishing the two conceptualizations is whether or not guilt is inherently adaptive construct, generating remorse, augmenting a sense of responsibility, and motivating reparation. Recommendations for the definition and measurement of guilt are discussed.

Adolescent substance use and abuse show associations with increases in disinhibitory constructs, including sensation seeking, risk taking propensity, and impulsivity. However, the longitudinal trajectories of these constructs from early to middle adolescence remain largely unknown. Thus, the current study examined these developmental trajectories in 277 adolescents (Mage = 11.00 at Wave 1), over five consecutive yearly waves. Controlling for age, Hierarchical Linear Modeling analyses showed that sensation seeking increased linearly, whereas risk taking propensity and impulsivity demonstrated curvilinear changes. Specifically, risk taking propensity increased in the first four waves of assessment but did not evidence changes at the last assessment wave. Impulsivity, on the other hand peaked at wave four before subsequently declining. A comparison between females and males and Black and White adolescents suggested that these groups’ trajectories were similar. Black adolescents’ sensation seeking trajectory differed from adolescents who belonged to the “Other” racial group (i.e., adolescents who neither self-identified as Black or White). Generally, the study findings replicate and extend earlier work indicating that these risk factors increase across early adolescence and begin to level-off during middle adolescence. The importance of understanding the natural course of these core constructs is of great importance for directing future relevant prevention and intervention work.

Mobile technologies can be leveraged to meet the need for evidence-based psychological depression treatment via primary care. The purpose of the present study was to preliminarily examine the feasibility and efficacy of a self-help Brief Behavioral Activation mobile application (app; "Moodivate") for depressive symptoms among adults treated via primary care. Participants (N = 52) were recruited from primary care practices between January and December 2017 and were randomized 2:2:1 to receive: 1) Moodivate, 2) an active control Cognitive Behavioral Therapy-based mobile app ("MoodKit"), or 3) Treatment As Usual (TAU; no app). Participants completed assessments of depressive symptoms weekly for eight weeks. App analytics data were captured to examine Moodivate feasibility (analytics unavailable for control app). Moodivate participants on average had 46.76 (SD = 30.10) app sessions throughout the trial duration, spent 3.50 (2.76) minutes using the app per session, and spent 120.76 (101.02) minutes using the app in

(1) Objective to find longitudinal evidence of the effect of targeted peer victimization (TPV) on depressive cognitions as a function of victimization type and gender. (2) Method Prospective relations of physical and relational peer victimization to positive and negative self-cognitions were examined in a one-year, two-wave longitudinal study. Self-reports of cognitions and both peer nomination and self-report measures of peer victimization experiences were obtained from 478 predominantly Caucasian children and young adolescents (grades 3 through 6 at the beginning of the study) evenly split between genders. (3) Results (a) peer victimization predicted increases in negative cognitions and decreases in positive cognitions over time; (b) relational victimization was more consistently related to changes in depressive cognitions than was physical victimization; (c) the prospective relation between victimization and depressive cognitions was stronger for boys than for girls; and (d) when the overlap between relational and physical TPV was statistically controlled, girls experienced more relational TPV than did boys, and boys experienced more physical TPV than did girls. (4) Conclusions Peer victimization, particularly relational TPV, has a significant impact on children’s depressive cognitions. This relation seems particularly true for boys. Implications for future research, clinical work with victimized youth at risk for depression, and school policy to help both victims and bullies are discussed.
