WHAT THE TEST MEASURES

About This Assessment

Personality Mental States Inventory (PII) Test - Symptoms and Signs

hopelessness loneliness hostility

In routine clinical and counseling settings, it can be helpful to efficiently characterize internal experiences that may be interfering with day-to-day functioning. The Personality Mental States Inventory (PII) is a brief self-report measure intended to screen for patterns of distressing or persistent negative mental states.

Respondents complete 36 items in about 7 minutes, endorsing statements that reflect common internal experiences such as loneliness, meaninglessness, inner conflict, irritability or anger, and hopelessness. Scores are typically used to inform clinical formulation, guide interview follow-up, and support monitoring over time, rather than to establish a diagnosis in isolation.

The Personality Mental States Inventory (PII) is commonly incorporated into psychological consultation, educational support contexts, and clinical care to help identify areas of emotional strain that may warrant further assessment. Authors: J. D. Dodson; R. M. Yerkes.
