توسعه و اعتبار مقیاس هیجان خواهی مبتنی بر MMPI

A measure of the sensation seeking construct was developed based on the MMPI item pool. An 18-item scale resulting from content and factor analysis had high test–retest reliability in a sample of 95 undergraduates. The scale showed good convergent and discriminant validity with respect to Zuckerman’s (1979) Sensation Seeking Scale Form V and predictive validity similar to that of the Sensation Seeking Scale when evaluated in a separate sample of 175 undergraduates. In a sample of 461 twin pairs the new scale had a heritability of 0.52, which is also similar to past results for the Sensation Seeking Scale. The results suggest that the new MMPI-based sensation seeking measure may be a useful alternative to previously developed measures of the construct, particularly in settings where the MMPI is already being collected for other reasons.
