Özet:

Rumination is defined as excessive thinking about causes or consequences of negative event or dwelling on negative mood experienced. In the literature, two types of rumination (anger and depressive rumination) have been identified. Ruminative style thinking increases through adolescence and predicts several internalizing and externalizing problems. However, despite the evidence on consequences, the studies focusing on their developmental antecedents are limited. Therefore, the current study aims to investigate the role of parenting (maternal psychological control and overprotection), co-rumination with mother and adolescent’s perfectionism as possible risk factors for anger and depressive rumination. Also, adolescent’s temperament (negative affectivity, perceptual sensitivity and effortful control) and gender is examined as potential moderators in the link between predictors and rumination. To this end, a total of 252 adolescents (Mage= 13.19 years) were recruited from 5 secondary schools in Çankaya and Mamak, Ankara. Unique and interaction effects were examined through four sets of hierarchical regressions for each type of rumination. The results showed that gender, maternal psychological control, v adolescent’s self-oriented perfectionism, and negative affectivity uniquely predicted anger and depressive rumination. Besides, co-rumination on mother’s problems predicted depressive rumination, while perceptual sensitivity predicted anger rumination. In addition to these unique effects, effortful control interacted with co-rumination on adolescent’s problems and overprotection in relation to both type of rumination. Also, negative affect-overprotection, perceptual sensitivity-co-rumination on adolescent’s problems and gender-maternal psychological control interactions were found significant in relation to anger rumination. The findings, contributions and limitations of the study were discussed
