The relationship between stroke survivors' perceived identity and mood, self-esteem and quality of life.

OBJECTIVES

To examine change in identity after stroke and to elucidate its relationship with mood and quality of life. To test Higgins' theory of the impact of identity (self-discrepancy) on anxiety and depression. To examine the role of self-esteem in mediating the relationship between identity and outcomes.

METHOD

Sixty-five community-living first-time stroke survivors, mean age 61.58 and time since stroke 5.60 years, were recruited from stroke charities. A cross-sectional study used the Head Injury Semantic Differential Scale, the Hospital Anxiety and Depression Scale, the Rosenberg Self-Esteem Scale, the Stroke-Specific Quality of Life Questionnaire (adapted) and the Barthel Index.

RESULTS

Identity was rated more negatively after stroke than before (t(64) = 6.46, p < .00). Greater discrepancy in identity was associated with anxiety (r = .38, p < .00), depression (r = .59, p < .00), self-esteem (r = -.48, p < .00) and quality of life (r = -.54, p < .00). Overall positivity of identity after stroke predicted outcomes even better than discrepancy. The association between discrepancy and mood and quality of life was mediated by self-esteem (β = .30, p < .01; β = -.24, p < .01, respectively). Specific types of discrepancy defined by Higgins did not show differential relationships with anxiety and depression as predicted.

CONCLUSIONS

Identity changes after stroke and identity and self-esteem are associated with important outcomes for stroke survivors.
