This volume comprises of a literature review and an empirical paper. The literature review explores the link between illness representations and self-management in children and young people with chronic illness. Fourteen published empirical studies were identified for the review. A risk of bias assessment was completed for each study. Consistencies and differences between papers were identified. Overall, treatment control beliefs were most consistently associated with self-management across a range of chronic health conditions. The empirical paper details a cross-sectional study investigating associations between illness representations, self-efficacy, self-management and psychological well-being in young people with Coeliac Disease. Forty young people and 34 parents recruited from hospital outpatient clinics completed questionnaires. Results indicated timeline-cyclical beliefs and treatment concerns were associated with self-management. Timeline-cyclical, identity, treatment control and coherence were correlated with well-being. In terms of self-efficacy, young people with high levels of self-efficacy were more likely to have better self-management and positive well-being. Finally, dissimilarity in timeline-cyclical beliefs between young people and their parents was related to higher parental stress.
