BACKGROUND: Psoriasis impacts patients' mental and physical health, prompting interest in psychosocial interventions. AIM: To compare and rank different psychosocial interventions for psoriasis and their effects on well-being and mental health. METHODS: A systematic search was conducted using Cochrane Library, EMBASE, Medline, and PsycINFO ( RESULTS: Thirteen studies with 6 treatments and 1233 patients were included. The quality of the included studies was low. For DLQI, 9 studies were eligible, mindfulness + treatment as usual (TAU) was better than TAU (MD = -7.21, 95%CI [-14.89, 0.54]). Cognitive behavioral therapy (CBT) + TAU were more effective in improving HADS-anxiety (MD = -2.17, 95%CI [-3.86, -0.49]) and HADS-depression (MD = -1.58, 95%CI [-3.65, 0.68]). Regarding adherence, CBT + TAU (MD = 0.84, 95%CI [-0.62, 2.27]) ranked first, followed by motivational interviewing + TAU. CONCLUSION: We confirmed the effectiveness of psychosocial interventions on patients' well-being and mental health and recommended several interventions for clinical practice. However, the results should be cautiously interpreted, due to lacking high-quality and more replication studies.
