Objective: The Self-Management of Well-being (SMW) group intervention for older women was implemented in health and social care. Our aim was to assess whether effects of the SMW intervention were comparable with the original randomized controlled trial (RCT). Furthermore, we investigated threats to effectiveness, such as participant adherence, group reached, and program fidelity.
Methods: In the implementation study (IMP) 287 and RCT 142 women participated. We compared scores on self-management ability and well-being of the IMP and RCT. For adherence, drop-out rates and session attendance were compared. Regarding reach, we compared participants' baseline characteristics. Professionals completed questions regarding program fidelity.
Results: No significant differences were found on effect outcomes and adherence between IMP and RCT (all p >= 0.135). Intervention effect sizes were equal (0.47-0.59). IMP participants were significantly less lonely and more likely to be married, but had lower well-being. Most professionals followed the protocol, with only minimal deviations.
Conclusion: The effectiveness of the SMW group intervention was reproduced after implementation, with similar participant adherence, minimal changes in the group reached, and high program fidelity. Practice implications: The SMW group intervention can be transferred to health and social care without loss of effectiveness. Implementation at a larger scale is warranted. (C) 2017 Elsevier B.V.
