This study explored the psychometric properties of the 30-item Mental Health Recovery Measure (MHRM) and a brief, ten-item version of the scale (MHRM-10) in a large, multisite sample of individuals with schizophrenia.
The sample consisted of 795 veterans with schizophrenia or schizoaffective disorder diagnoses who were receiving mental health services in one of eight Veterans Health Administration medical centers across four regions of the United States. Exploratory factor analysis was used to examine the factor structure of the MHRM and to select the most appropriate ten items for the brief measure. Correlations of the MHRM and the MHRM-10 with measures of quality of life, satisfaction with mental health services, symptom severity, and functioning were computed to further establish construct validity. Cronbach’s alpha was used to assess the internal reliability of the MHRM and MHRM-10.
Factor analysis resulted in an interpretable single-factor solution. The MHRM-10 was established by selecting the ten items with the highest factor loading scores. MHRM and MHRM-10 total scores correlated strongly and positively with quality-of-life measures (overall, leisure, general health, and daily activities) and negatively with depressive mood. Negligible correlations existed between the MHRM instruments and measures of functioning and satisfaction with services. Both instruments demonstrated excellent internal consistency.
This study provides initial support for use of the MHRM-10 as a brief, valid, and reliable assessment of perceived recovery among individuals with schizophrenia and one that may be easily used in routine care.
