The article by Steven D. Hollon and Philip C. Kendall from the University of Minnesota describes the development of a 30-item questionnaire, the Automatic Thoughts Questionnaire (ATQ-30), to measure the frequency of automatic negative thoughts (negative self-statements) associated with depression. The questionnaire was administered to male and female undergraduates who recalled dysphoric experiences and reported associated cognitions. One hundred representative cognitions were selected and administered to a second sample, along with the MMPI D scale and the Beck Depression Inventory. The ATQ-30 was found to significantly discriminate between psychometrically depressed and nondepressed subjects, with no differences between males and females. Factor analysis revealed a four-factor solution: Personal Maladjustment, Negative Self-Concept and Negative Expectations, and two lesser factors. The ATQ-30 is proposed as a tool to test theories relating cognitive content to behavioral and affective processes and to assess changes in cognitions associated with experimental manipulation or psychotherapeutic intervention.The article by Steven D.
