Abstract
The aim of the current systematic review is to examine relationships among illness identity and illness-specific variables, adherence, and health-related outcomes. Studies were included if they (a) presented quantitative data on illness identity’s relationship with adherence or health-related outcomes, (b) included chronic medical illness samples, (c) were peer-reviewed, and (d) were available in English. PubMed and EBSCOhost were searched. Quality was evaluated using the EPHPP Tool. Twelve papers were included. Moderate evidence supports the relationship between engulfment, enrichment, and illness complexity. Moderate evidence supports relationships between multiple identities and adherence as well as with various health-related outcomes. There is somewhat consistent evidence for associations between engulfment and negative health-related outcomes. It may be important to inform healthcare providers of possible identity challenges that patients face and their associations with adherence and health-related outcomes. Routine illness identity screening may allow for identification of individuals who would benefit from increased support.
