Effect of Psychological Intervention on Quality of Life Among Patients with Psoriasis: A Meta-analysis.

BACKGROUND

Psychological distress can significantly obstruct the treatment outcomes of patients with psoriasis. This meta-analysis aimed to examine the effects of psychological intervention on the mental health and functional capabilities in patients with psoriasis.

METHOD: PubMed, EMBASE, and Cochrane Library were searched for relevant studies published up to May 1, 2023. The primary outcome was a change in anxiety, depression, and quality of life (QoL). Standardized mean difference (SMD) was calculated, and 95% confidence interval (CI) was determined for the estimation.

RESULTS

This meta-analysis involved 1048 subjects, including 515 patients who received psychological interventions and 533 patients in control groups who did not receive psychological interventions. The results showed that psychological intervention significantly improved anxiety symptoms (SMD - 0.41; 95%CI - 0.77, - 0.05; I2 = 71.5%; PHeterogeneity = 0 .001). There was no significant improvement in the symptoms of depression (SMD - 0.52; 95%CI - 1.13, 0.10; I2 = 86%; PHeterogeneity < 0 .001) and QoL (SMD - 0.05; 95%CI - 0.22, 0.11; I2 = 39%; PHeterogeneity = 0 .108) in patients who received psychological intervention compared with controls.

CONCLUSION

Psychological intervention ameliorated anxiety symptoms in patients with psoriasis but had no significant impact on depression or QoL.
