Predicting and understanding seasonal influenza vaccination behaviour among forensic mental health inpatients

Abstract

Objectives This study aimed to identify demographic and psychological predictors of seasonal influenza vaccination intentions and behaviour among a sample of inpatients in a secure forensic mental health service. It also sought to explore patient experiences about being offered the vaccine. Design This study used a mixed-methods design. The quantitative element employed a prospective design using a questionnaire; both cross-sectional and prospective findings are reported. For the qualitative part of the study, semi-structured interviews were conducted and analysed using Interpretative Phenomenological Analysis (IPA). Main outcome measures Seasonal influenza vaccination intentions and behaviour Results Past behaviour, vaccine knowledge and cues to action were predictors of vaccination intention (N = 57). Cues to action remained as the only statistical predictor of vaccination behaviour (N = 55). Nine interviews were conducted with four vaccinated and five unvaccinated participants. Three main themes were formed in the IPA analysis; these were ‘Managing Decisional Conflict’, ‘Interaction with Immune Function’ and ‘The Role of Others’. Conclusions The results highlighted the integral role of health professionals in shaping patient’s vaccination behaviour within a secure mental health setting. Recommendations for vaccination promotion strategies were offered.
