Greater catastrophising in individuals who report a psychiatric diagnosis or use of psychiatric medication

Pike, Alexandra C., Jade Serfaty, and Oliver J. Robinson. 2020. “The Development and Psychometric Properties of a Self-report Catastrophising Questionnaire.” PsyArXiv. March 24

Abstract: Catastrophising can be defined as imagining or predicting the worst possible outcome. It has been shown to be related to psychiatric symptoms such as depression and anxiety, yet there are no self-report questionnaires specifically measuring it outside the context of pain research. Here, we therefore develop the Catastrophising Questionnaire, a comprehensive self-report measure of general catastrophising. Across four experiments (total n=734), using a combination of exploratory then confirmatory factor analysis, we conclude 1) that our questionnaire is best fit by a single factor structure; and that 2) catastrophising is independent from other self-reported psychiatric symptoms. Moreover, we demonstrate 3) greater catastrophising in individuals who report a psychiatric diagnosis (t139.12=8.54, p<.001) or use of psychiatric medication (t67.44=7.53, p<.001). Finally, we demonstrate that 4) our Catastrophising Questionnaire has good test-retest reliability (ICC(A,1)=0.77, p<.001). Critically, we can now, for the first time, measure aspects of this debilitating psychiatric symptom.
