Effectiveness, Implementation and Spillover Effects of a Culturally Adapted DPP in Spanish Primary Care Centers

Sponsor: University of the Balearic Islands

Summary

The ALADIM trial is a hybrid type II effectiveness-implementation cluster-randomized controlled, parallel, two arm, superiority trial. The clusters consist of 10 Primary Care Centers (PCCs) of Mallorca (Balearic Islands, Spain), which are randomly assigned to either the intervention or the control group in a 1:1 ratio. The intervention group (5 PCCs) receives training and supporting material to facilitate the implementation of the adapted DPP and effectively deliver the program over a 12-month period. The control group (5 PCCs) continues providing usual care, in line with standard healthcare practices. Effectiveness outcomes are assessed at participant level according to a cluster-randomized controlled design with data collection at baseline, 6-month and 12-month during the intervention period, and at 18-month follow-up to evaluate mid-term effects post-intervention. Implementation outcomes are assessed at PCC level throughout the study period. Prior to the hybrid trial, the DPP will be culturally and contextually adapted to the Spanish Primary Care setting. The DPP will be culturally adapted using the Intervention Mapping ADAPT (IM-ADAPT) approach. Simultaneously, the implementation strategy will be designed using the Implementation Mapping approach.
