Reliability And Validity Of A Further Tested Appreciative Management Scale

Background and Purpose: Managers need evidence-based methods to evaluate their management skills. To further test the appreciative management scale (AMS 1.0) to create a practical instrument to be used in evaluating appreciative management. Methods: For further testing, a new survey was conducted among social and healthcare managers (n = 734) in Finland. Confirmatory factor analysis (CFA) was used to assess the scale validity and Cronbach's alpha coefficients the internal consistency. Results: The validated AMS 2.0 scale includes 24 items. The values measuring validity and reliability were good, with an Root Mean Square Error of Approximation (RMSEA) of 0.072, Average Variance Extracted (AVE) values between 0.532 and 0.634, and Composite Reliability (CR) values ranging between 0.850 and 0.914. The Cronbach's alpha of the whole scale was 0.944. Conclusions: AMS 2.0 is a reliable and valid means to measure appreciative management as proved by confirmatory factor analysis.
