Psychological predictors of seasonal influenza vaccination uptake among adults with a high-risk physical health condition: a systematic review.

This review tested the use of psychological theories for predicting seasonal influenza vaccination behaviour among adults with a health condition (for which the vaccine is clinically indicated). Ovid (1946–August 2018), Embase (1974–August 2018), CINAHL (1958–August 2018) and PSYCInfo (1986–August 2018) databases were searched. Studies drawing upon a psychosocial or psychological theory to explain seasonal influenza vaccination behaviour among adults with a high-risk health condition were eligible for inclusion. Papers were systematically extracted by title, abstract and full text. Quantitative and qualitative studies were included, and all papers were quality assessed. A total of 4840 papers were identified after removal of duplicates. Twelve papers were retained in the narrative synthesis. Studies were conducted across a range of high-risk condition populations and most (83.3%) were cross-sectional. The Health Belief Model (HBM), the model of Psychological Flexibility, The Health Action Process Approach and House's Framework of Social Support were applied. Ten out of 12 papers (83.3%) drew on the HBM. There was evidence of an association between HBM perceived benefits, perceived barriers and vaccination behaviour, although there were inconsistencies across studies. This review highlighted the need for further research, particularly prospective studies of high methodological quality. [ABSTRACT FROM AUTHOR]
