HABIT (Health visitors delivering Advice in Britain on Infant Toothbrushing): a qualitative exploration of the acceptability of a complex oral health intervention.

backgroundTo explore the acceptability of the oral health intervention, HABIT (Health visitors delivering Advice in Britain on Infant Toothbrushing) to parents with young children aged 9-12 months and health visitors.

methodsFollowing the delivery of the universal oral health intervention called HABIT, qualitative semi-structured interviews with parents and focus groups with health visitors were undertaken. Interviews were audio-recorded and transcribed. Health visitors completed self-reported diaries after delivering the HABIT intervention with parents. The qualitative data was analysed using framework analysis (guided by a theoretical framework of acceptability).

resultsSeventeen parents were interviewed, and five health visitors and three nursery nurses participated in two focus groups. Parents reported health visitors to be 'trusted' and valued the reassurance provided during the HABIT visit. Health visitors found the HABIT training and resources useful and valued the consistency and increased confidence in undertaking oral health conversations. There were, however, challenges in changing behaviour where families faced competing demands on time and resources. Both health visitors and parents described the importance of the intervention's timing and suggested that multiple visits may be needed to support optimal oral health habits.

conclusionThe HABIT intervention was acceptable to parents and health visitors. Health visitors would welcome a further refinement to enhance intervention delivery that specifically achieves a balance between using a guided script and retaining the flexibility to adapt the conversation to suit the needs of individual families. This, in turn, will maximise impact and enable parents of young children to adopt and maintain optimal home-based oral health behaviours for their child.
