Factor structure of Beck's Suicide Intent Scales.

Abstract

Data obtained from 48 suicide attempters and 56 suicide threateners on three of Beck's suicide intent scales were factor analyzed. The scale, attempt suicide intent, yielded four orthogonal factors reflecting seriousness of intent, lethality of the act, precautions against interference and failure to initiate rescue after the attempt. The current scale of suicidal intent yielded four factors, bur one, the still suicidal factor, accounted for 44% of the variance. The suicide ideators scale yielded a general factor, called specificity of planning, accounting for more than half the variation. Factor scores were computed and correlated with diagnostic groupings. Character disordered subjects were more likely to report both more serious intent at time of suicide attempt and at interview than other attempters.
