 This study aimed to develop and assess the reliability and validity of three new outcome measures for monitoring and evaluating implementation efforts, acceptability of intervention measure, AIM, intervention appropriateness measure, IAM, and feasibility of intervention measure, FIM. The study used a mixed methods approach including content validation, exploratory and confirmatory factor analysis, and test-retest reliability. Results showed that all but five items exhibited substantive and discriminant content validity, and the three measures demonstrated acceptable model fit and high factor loadings. An overshoot significant main effects, indicating known groups validity, and test-retest reliability coefficients ranged from 0.73 to 0.88. Regression analysis indicated each measure was sensitive to change in both directions. The study concludes that the AIM, IAM, and FIM demonstrate promising psychometric properties and predictive validity assessment is planned. This article was authored by Brian J. Weiner, Kara C.
