Measuring personal loss among adults coping with serious mental illness.

Psychometric properties of a brief self-report measure of personal loss for adults coping with psychiatric disability are examined. The Personal Loss from Mental Illness Scale (PLMI) is a 20-item measure that assesses overall perceptions and four interrelated aspects of personal loss from mental illness. Using a sample of 158 adults with serious mental illness, the PLMI was found to have a meaningful factor structure, good internal consistency and high test-retest reliability. Construct validity is evidenced by positive correlations between personal loss scores, number of psychiatric hospitalizations, self-reports of loneliness, psychological symptoms, and problems with alcohol. PLMI scores were unrelated to scores on a personal growth measure and negatively correlated with scores on a positive well-being scale. Implications of the PLMI for research on coping, adaptation and recovery from serious mental illness are discussed.
