Objective: This qualitative study embedded within a randomized controlled trial was conducted to explore the acceptability, experiences of, and short-term impact of a preventive health intervention (Lifestyle Matters) from the perspectives of those who took part, and to uncover any evidence for the theorised mechanisms of action (improved participation and self efficacy) underpinning the intervention. It was also conducted to help explain the quantitative trial results.
Methods: A purposive sample of 13 trial participants who had been randomized to receive the Lifestyle Matters intervention (approximately 10%) were individually qualitatively interviewed immediately following their involvement. All four intervention facilitators were also individually interviewed.
Results: Evidence of the hypothesized behavioural changes could be identified within the interview data, demonstrating the potential of this intervention. However, lack of adherence to the overall intervention eroded receipt of benefit. This finding complements the quantitative trial results which found that the study had failed to recruit those who considered themselves to be at risk of age-related decline.
Conclusion: This form of preventive health intervention requires proactive identification of those who recognise the need to make lifestyle changes. This is difficult if reactive health and social care systems are the main referral routes. The methodological approaches taken towards the study of complex interventions requires reconsideration if potential benefits are to be accurately assessed.
