Adaptation of Nussbaum's Capabilities Framework to Community Mental Health: A Consumer-Based Capabilities Measure.

The capabilities approach provides a rich evaluative framework to guide transformative change in the community mental health system. This study reports the content and construct validity and psychometric properties of a contextualized measure of the extent to which mental health programs foster achieved capabilities. The Achieved Capabilities Questionnaire for Community Mental Health (ACQ-CMH), adapted from Nussbaum's capabilities framework, was developed previously with consumer collaboration. Content validity was assessed through a collaborative process, involving a panel of eight consumers, staff members, and senior researchers. The resulting shorter version (ACQ-CMH-98) was completed by 332 community mental health consumers sampled throughout Portugal. Factor (PCA) analysis, internal consistency reliability, and test-retest reliability over 2 weeks (N = 33) showed good psychometric properties. The resulting six-factor structure with 48 items explains 48.88% of the total variance (KMO = 0.89; Bartlett p = .00). Internal consistency of the obtained dimensions ranges from .91 to .76. Associations of the measure with recovery, quality of life, and psychological distress scales add further evidence of construct validity. The adaptation of Nussbaum's framework stressed specific components that may enhance understanding and change within the community mental health system.
