Psychologic factors in psoriasis: consequences, mechanisms, and interventions

The article examines the English-language research literature concerning psychologic aspects of psoriasis published since 1995. The literature is concerned with (1) the consequences of psoriasis in terms of quality of life, disability, depression, anxiety, and stigmatization and factors that may predict such outcomes; (2) potential mechanisms of the interaction between psychologic factors, stress, and the pathophysiology of psoriasis; and (3) examination of the clinical utility of psychologic interventions on extent of psoriasis and psychologic distress. The implications of the findings are discussed with reference to future directions for research and practice.
