Divergent beliefs about psoriasis are associated with increased psychological distress

The psychological adjustment of patients with psoriasis has been studied extensively. By comparison, no research has focused on their partners. We examined illness representations of psoriasis held by patients and their partners, and investigated whether divergent beliefs were associated with psychological distress. Fifty-eight patients with chronic plaque psoriasis and their partners completed a range of psychological assessments including beliefs about the condition, anxiety, depression, and worry. Patients also completed a self-assessment of psoriasis severity. Patients with psoriasis had significantly higher levels of anxiety, depression, and worry than their partners (t's > 2.53, p's < .05). Multiple regression analysis indicated that divergence in patients' and partners' beliefs about emotional impact of psoriasis and chronicity of timeline accounted for a statistically significant (21.3%) proportion of the variance in depression for partners. Differences in views on the consequences of having psoriasis and the cyclical nature of the condition were also significantly associated with increased levels of worry in partners. Dissimilarity in particular aspects of illness representations are associated with increased psychological distress in particular for the partners of patients with psoriasis. The results illustrate the importance of concordance between patients' and partners' models of illness in relation to adjustment, and highlight the need to consider and collaborate with both patients and their partners in managing this challenging condition.
