THE ATTRIBUTIONS FOR INTERNAL EVENTS SCALE - PSYCHOMETRIC PROPERTIES

The present research was devoted to the development and psychometric e valuation of the Attributions for Internal Events Scale (AIES)-an inst rument designed to measure attributions for those internal, biological events typically associated with circadian dysrhythmia and frequently reported by depressed persons. Four studies, assessing over 500 parti cipants, were completes. The studies differed with regard to the parti cular measure(s) of well-being; test-retest reliability of the AIES wa s assessed in one study, and the Attributional Style Questionnaire (AS Q) was administered in one study for comparison. Coefficients of inter nal consistency indicated adequate to superior reliability for basic a nd composite scales of the AIES. Across studies, the controllability a nd composite scales were consistently and highly correlated with vario us measures of well-being. Further, regression analyses indicated that the AIES, in accounting for variability in well-being, may incorporat e and go beyond that due to attributions for external events.
