Temporal Stability and Predictive Validity of the Alternative Model of Personality Disorders Among Older Adults

Abstract: The alternative model of personality disorders (AMPD) contains two diagnostic criteria: personality functioning and pathological personality traits. This study examined the temporal stability and predictive validity of the AMPD’s key constructs among older adults. A sample of older adults ( n = 172) completed AMPD and psychosocial functioning measures 3 months apart. Results indicated mixed evidence of the AMPD’s temporal stability among older adults. Predictive validity was supported, indicating that AMPD may be an adequate prognostic indicator in late life. This study provides further evidence in support of the validity and clinical utility of the AMPD among an older adult population, although some important areas of improvement remain. We discuss the findings in light of the broader PD, AMPD, and older adult personality literature.
