OBJECTIVES (a) Describe levels of physical and global self-esteem and (b) explore the relationships between these types of self-esteem and physical activity (PA) behaviour, self-efficacy for PA and physical self-perceptions among adolescent and young adult (AYA) cancer survivors. METHODS A total of 87 AYA cancer survivors (Mage  = 32.90 ± 4.38 years), who were on average 2.08 ± 1.37 years post-treatment, participated in this cross-sectional observational study. Descriptive statistics, correlations and hierarchical multivariate linear regression analyses were used to analyse the data. RESULTS Moderate levels of physical and global self-esteem were reported. Both types of self-esteem were significantly related to physical self-perceptions, but not to PA behaviour nor self-efficacy for PA. Self-efficacy for PA moderated the relationship between physical self-perceptions and physical self-esteem, such that the association between physical self-perceptions and physical self-esteem was of stronger magnitude at higher levels of self-efficacy for PA than at lower levels of self-efficacy for PA. CONCLUSION This study provides a starting point for describing self-esteem and identifying the circumstances under which self-esteem may be optimised among AYA cancer survivors. Fostering feelings of confidence, competence and control over PA may help to promote psychological well-being among AYA cancer survivors.
