Healthy Habits, Happy Homes (4H) is a home-based, pre-school childhood obesity prevention intervention which demonstrated efficacy in North America which we translated to Scotland (4HS) by considering contextual factors and adapting study design. RE-AIM Framework was used to assess 1) extent to which development of 4HS intervention (including recruitment) was participatory and inclusive; 2) feasibility of translating a complex public health intervention from one setting to another; 3) extent to which translation was pragmatic and 4) fidelity of intervention to the principles of Motivational Interviewing (MI).

Study design
Feasibility testing, process evaluation and measurements of intervention fidelity were undertaken to evaluate the translation of 4H to an economically deprived area of Scotland (4HS).

4HS study processes; participatory approach, recruitment methods, level of pragmatism were evaluated using the RE-AIM framework. Qualitative and quantitative measures identified key implementation features and functioning of 4HS intervention. Fidelity MI principles was determined through coding of audiotapes using Motivation Interviewing Treatment Integrity (MITI) code.

Key facilitators for positive impact with families, included: inclusive recruitment methods, appropriate channels of communication and correspondence (Reach) with n ​= ​126 enquiries and n ​= ​26 (21%) families recruited. Positive links with local parents and community workers integral to the research process at n ​= ​9 meetings (Effectiveness). 61.5% of families lived in the most deprived data zone in Scotland, 23% were one parent families, thus awareness and consideration of local contextual factors (Adoption) and locally relevant materials were important. 4HS was feasible to deliver, pragmatic in nature and intervention demonstrated good fidelity to MI (Implementation).

Translation of 4H from North America to Scotland was successful. Future studies should consider implementation of 4HS approach within routine practice within the UK (practice based evidence) or through thoughtful evaluation in a future trial (evidence based practice).
