The dataset contains SpSS (.sav) and .csv files of self-report data from all research participants. Descriptions of variables can be found in the file. The aim of this research is to examine the relations between self-cognitions and depression in adolescents, as well as the influence of parenting behaviour on these processes. Two-hundred and forty-three Grade 7 students were followed over a two-year period, with self-report data collected at three time-points. They reported on their self-esteem, self-criticism, and depression, as well as parenting behaviours. Parents also provided self-report data at time one. Noting here that all identifying material has been removed.
