In the first study, a combined sample of mature students, depressed and formerly depressed patients, and the patients first degree relatives completed either Form A or Form B of the Dysfunctional Attitude Scale (DAS). Factor analysis of the two sets of data suggest that, contrary to the original proposals, the two versions of the DAS are not equivalent when a wide range of respondents are sampled. A second study presents preliminary information about a 24-item DAS which can be used to derive three subscale ratings related to Achievement, Dependency, and Self-Control. It is proposed that such subscales may be the preferred way of pursuing possible vulnerability factors rather than seeking more global effects.
