OBJECTIVE Intentional Peer Support (IPS) is a peer-developed, theoretically based, manualized approach that is used in multiple countries. This research aimed to develop and test a measure that can be administered to service users to provide quantitative data for assessing IPS core competencies (IPSCC) in outcomes research. METHODS Ten items based on IPSCC dimensions were developed and revised in an iterative process and administered in face-to-face interviews with 84 respondents. Internal consistency, test-retest reliability, and convergent validity were examined. RESULTS The IPSCC measure demonstrated good internal consistency (Cronbach's alpha of .85) and 2-week test-retest reliability (r = .98, p < .001), as well as satisfactory convergent validity. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE This study provides a foundation for future process-oriented research on IPS, and potentially other forms of peer support, to systematically document and appraise participant experiences.
