Measuring illness management outcomes: a psychometric study of clinician and consumer rating scales for illness self management and recovery.

Psychometric properties of the Illness Management and Recovery (IMR) Scales (consumer and clinician versions), new 15-item instruments measuring illness self-management and pursuit of recovery goals, were evaluated in consumers with severe mental illness. Both versions had moderate internal consistency and high 2-week test-retest reliability. In addition, the consumer version was correlated with self-ratings of recovery and symptoms, and the clinician version was correlated with clinician ratings of community functioning, indicating convergent validity. The results suggest the IMR Scales have adequate psychometric properties and may be useful in treatment planning and assessing recovery in individuals with severe mental illness.
