Choosing Health: acceptability and feasibility of a theory-based, online-delivered, tailored weight loss, and weight loss maintenance intervention

Abstract

Few weight loss and weight loss maintenance interventions are tailored to include factors demonstrated to predict the user’s behavior. Establishing the feasibility and acceptability of such interventions is crucial.The aim of this study was to assess the acceptability and feasibility of a theory-based, tailored, online-delivered weight loss and weight loss maintenance intervention (Choosing Health). We conducted a mixed methods process evaluation of the Choosing Health tailored intervention, nested in a randomized controlled trial (N = 288) with an embedded N-of-1 study, investigating participants’ and implementers’ experiences related to intervention context, implementation, and mechanisms ..
