RESUMO
OBJECTIVES: To test the centrality of injury to self-concept as a moderator of the associations between injury perceptions and outcomes. METHODS: Two concurrent studies on samples of injured individuals. MEASURES: The centrality of injury to one's self concept was measured by the degree of self-injury separation (PRISM); injury perceptions were measured by the injury perception questionnaire; and outcomes by standard scales of self-assessed health, physical, emotional and social functioning, vitality, depression, anxiety and somatisation. Regression analyses examined the significance of adding the interactions between injury centrality and injury perceptions to explained outcome variance, beyond their separate contributions. RESULTS: Both injury centrality and injury perceptions significantly explained variance in patients' functioning and well-being. Injury centrality moderated the associations between various injury perceptions and outcomes, especially pronounced for emotional representations of the injury. As hypothesised, the effects of injury perceptions on outcomes were stronger among patients for whom the injury was central to their self-concept compared to patients who perceived the injury as peripheral to their self-concept. CONCLUSIONS: 'Centrality to the self' is a moderator of the impact of perceptions on outcomes of injuries. The findings suggest ways to tailor interventions to sub-groups of injured patients based on injury centrality to their self-concept.
