PROTOCOL: A comparison of the effectiveness of cognitive behavioural interventions based on delivery features for elevated symptoms of depression in adolescents.

This is the protocol for a Campbell review. The primary aim is to estimate the relative efficacy of different modes of CBT delivery compared with control conditions for reducing depressive symptoms in adolescents. The secondary aim is to compare the different modes of delivery with regards to intervention completion/attrition (used as a proxy for intervention acceptability).

An observational study of social exclusion under varied conditions: gender and developmental differences.

To investigate social exclusion, 146 dyads of close friends (N = 292, ages 10, 12, and 14) were observed as they played a board game with a same-gender confederate actor, trained to be a difficult play partner. Verbalizations and gestures were coded for verbal and nonverbal social exclusion, verbal aggression, and verbal assertion. The results indicated few developmental differences.
