Overgeneralization: an important but non-homogeneous construct.

Two self-report scales--the Cognitions Questionnaire (Fennell & Campbell, 1984) and the Attitudes to Self Scale (Carver & Ganellen, 1983)--which attempt to measure overgeneralization in depression are described. In line with previous research, both measures correlated with levels of depression, but the lack of a direct relationship between them implies that the construct of overgeneralization may not be a homogeneous one. Suggestions are made for future research which include elaboration of the construct and the development of new methods for measuring it.
