Hollon and Kendall's (1980) Automatic Thoughts Questionnaire (ATQ-30) was designed to identify and measure the frequency of occurrence of automatic negative thoughts associated with depression. This 30-item self-statement inventory was constructed and cross-validated using male and female undergraduates as subjects. The present study examined the applicability of the ATQ-30 to clinical populations. Compared to nondepressed mental-health-center clients and nondepressed medical patients, significantly higher ATQ-30 scores were found for mental-health-center clients who met the criteria for inclusion in a depressed group. The ATQ-30 correlated significantly with therapist ratings of depression, the Minnesota Multiphasic Personality Inventory Depression scale, and the Beck Depression Inventory. Splithalf and coefficient alpha reliability coefficients were also highly significant, as were item-to-total correlations. The ATQ-30 appears to be a valid and reliable measure of depression-related cognitions in clinical as well as nonclinical populations.
Psychiatric patients were administered the Minnesota Multiphasic Personality Inventory (MMPI), its revision (MMPI-2), or both, in a counterbalanced repeated-measures design. MMPI-2 T scores were found to be significantly lower than MMPI T scores on several of the clinical scales. Subject rank order on T scores and dispersion of the basic clinical scales did not differ between the tests, and measures of profile similarity indicated congruence between the two instruments. Among subjects who completed both the MMPI and the MMPI-2, code-type concordance was not significantly lower than stability rates of the tests. The results support the assignment of 65T as the lower boundary of clinical elevation on the MMPI-2 and the psychometric equivalence of the MMPI-2 and the MMPI with respect to mean r scores, score rankings, and measures of score distribution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
