Background A challenge to implementation is management of the adaptation-fidelity dilemma or the balance between adopting an intervention with fidelity while assuring fit when transferred between contexts. A prior meta-analysis found that adapted interventions produce larger effects than novel and adopted interventions. This study attempts to replicate and expand previous findings. Methods Meta-analysis was used to compare effects across a whole-population of Swedish outcome studies. Main and subcategories are explored. Results The 523 studies included adapted (22%), adopted (33%), and novel (45%) interventions. The largest effect was found for adapted followed by novel and adopted interventions. Interventions in the mental health setting showed the highest effects, followed by somatic healthcare and social services. Conclusions These results replicate and expand earlier findings. Results were stable across settings with the exception of social services. Consistent with a growing body of evidence results suggest that context is important when transferring interventions across settings.

Background. Several approaches to the implementation of evidence-based interventions (EBIs) are currently in use. EBIs may be adapted or adopted from previous settings or novel interventions may be developed to achieve public health goals. Within the intervention and implementation literature, a major unsolved dilemma relates to the management of adaptation versus fidelity when EBIs are transferred between settings. An initial attempt to empirically understand this dilemma was made in 2015 which explored meta-analytically the origins of interventions and compared their effect sizes. It was found that adapted interventions produced the highest effect sizes followed by novel and adopted interventions. The current study attempts to replicate these findings using a larger data set. Methods. We used meta-analytic techniques to compare effect sizes across a population of Swedish efficacy and effectiveness studies. Interventions investigated were categorized into adapted, adopted, and novel interventions. Nine subcategories were explored. In addition, we explored differences in effect sizes between settings as well as the impact of study characteristics on effect size. Results. Of the 523 studies included, 22% described adapted interventions, 33% adopted interventions, and 45% novel interventions. The largest effect size was found for adapted interventions followed by novel and adopted interventions. Standard mean effects were significantly different from zero across categories. Study characteristics did not have a large impact on effect size, but interventions provided in the mental health setting showed the highest standard mean difference, followed by somatic healthcare and social services. Conclusions. The results reported here are in line with a growing body of evidence suggesting that there is a need to take the fit between the EBI and the context into account when implementing interventions.
