Psychometric Testing of the German Versions of Three Implementation Outcome Measures

Abstract Internationally comparable assessments of implementation outcomes are a prerequisite for the accurate and useful exchange science results. We translated English versions acceptability intervention measure (AIM), appropriateness (IAM), feasibility (FIM) into German following recent guidelines. tested structural validity, internal consistency (Cronbach’s α ), construct validity (known-groups validity) in hypothetical situation study secondary school teachers ( n 1 = 142) pilot field primary participating health promotion project 2 61). The hypothesized three-factor solution (acceptability, appropriateness, feasibility) revealed best model fit (CFI 0.97; RMSEA 0.08). second tended to support these results 0.99; 0.05) only when error terms two items from different constructs were allowed correlate with each other (“seems like good match” [IAM] “seems possible” [FIM]). Furthermore, intercorrelations between three factors higher than vignette (0.71–0.86 vs. 0.06–0.35). instruments’ proved be high both studies : 0.91–0.97). gathered positive evidence known-groups as participants who received stimuli before answering instruments rated them statistically significantly different. Our showed that could successfully applied research. suggest using four per instrument rather an abbreviated version discuss recommendations application.
