A reanalysis of the self-appraisal questionnaire: psychometric properties and predictive validity.

ABSTRACT

This research reassessed the psychometric properties and predictive validity of the Self-Appraisal Questionnaire (SAQ) in response to published criticism of the authors' earlier work. The current research used a much longer recidivism tracking-period, a different measure of recidivism, a larger sample, and more advanced analytic techniques than the original. Examination of the SAQ's psychometric properties continued to indicate that three of the six recidivism prediction subscales exhibited substandard levels of reliability and four of these subscales were not unidimensional. Yet, in contrast to the author's earlier results, the current analyses found that SAQ total score modestly predicted reconviction.
