Abstract OBJECTIVES: To identify explanations for adherence to self-care behaviours amongst adolescents with food allergy-induced anaphylaxis using two social cognition models: the health belief model (HBM) and the common sense self-regulation model (CS-SRM). DESIGN: Cross-sectional self-completion questionnaire study to gain initial evidence of the two models' feasibility/effectiveness in explaining adherence in an adolescent food-allergic population. METHODS: Participants aged 13-19 years with a diagnosis of severe food allergy and a prescription of an adrenaline auto-injector were recruited from hospital outpatients. Adherence to self-care behaviours was measured in addition to constructs from the HBM and CS-SRM. RESULTS: One hundred and eighty-eight food-allergic adolescents completed the questionnaire. The HBM, specifically the constructs perceived severity and barriers, accounted for 21\% of the explained variance in adherence behaviours. CS-SRM constructs, illness identity, timeline cyclical beliefs and emotional representations explained 25\% of the variance. CONCLUSIONS: Both models performed similarly in explaining adherence to self-care behaviours in adolescents with food allergy. Interventions designed to elicit personal barriers to adherence and to address perceptions of severity and the unpredictable nature of symptoms may be more effective in improving adherence to self-care behaviours than current interventions. © 2013 The British Psychological Society.
