Abstract

Few studies have assessed the psychometric properties of the Personality Assessment Inventory short-form (PAI-SF) clinical scales, and none have conducted these evaluations using participants from psychiatric inpatient units. The present study evaluated item-level tests of scaling assumptions of the PAI-SF using a large (N = 503) clinical sample of participants who completed the PAI during their admission to a psychiatric inpatient unit. Internal consistency reliability was high across scales, and tests of item-scale convergence and discrimination generally confirmed hypothesized item groupings. Scale-level correlations supported unique variance being measured by each scale. Finally, agreement between the PAI short- and full-form scales was found to be high. The results are discussed with regards to scale interpretation.
