Process evaluation of the HIKCUPS study: a multi-site randomised controlled trial for the management of child obesity
Objective: The purpose of this paper is to outline findings from the process evaluation of a multi-site randomised controlled trial for management of child obesity, known as the HIKCUPS study . The key areas evaluated included the delivery and fidelity of the three treatment arms and various quality assurance practices. Design: Process data were collected using a variety of methods: facilitator evaluations and reviews of each session, independent session observation, attendance records and parent questionnaires. Results: 97% of the planned content was delivered at both sites, irrespective of the intervention. Facilitator review of the physical activity program indicated that future programs for overweight children should cater for children of similar age or same sex. Program attendance ranged from ~70% to 78%. All parents agreed that the dietary modification program had made a difference to both their family's and their child's eating habits. Parents reported positive changes (self confidence, motivation, activity in daily life) in their children as a result of the physical activity program. Most participants completed the suggested home activities but more than 60% of those in the physical activity program reported finding time to do these problematic. Conclusions: Process evaluation of the HIKCUPS study indicated that the interventions were delivered consistently and as intended across the sites, the content of the intervention programs appears to have been appropriate and achieved the desired reach. Quality assurance standards were attained. 1. Jones RA et al.
