Dysfunctional Attitudes and Suicidal Ideation in Psychiatric Outpatients

Abstract

To determine if specific sets of dysfunctional attitudes were related to suicidal ideation, the 100‐item Dysfunctional Attitude Scale (DAS) was administered to 908 psychiatric outpatients along with the Beck Depression Inventory (BDI), Hopelessness Scale (BHS), Self‐Concept Test (BST), and Scale for Suicide Ideation (SSI). The SSI was used to classify the outpatients into 97 (10.7%) suicide ideators and 811 (89.3%) nonideators, and the DAS was scored for nine subscales described by Beck, Brown, Steer, and Weissman (1991). None of the DAS subscales discriminated the ideators and nonideators or was significantly related to SSI total scores of the suicide ideators after controlling for sex, age, diagnosis of a mood or panic disorder, comorbidity, presence of a personality disorder, a history of a past suicide attempt, the BDI, the BHS, and the BST. The contributions of sets of dysfunctional attitudes for identifying and explaining suicidal ideation were overshadowed by a history of a past suicide attempt and hopelessness.
