Background: Psoriasis has been known to be associated with various psychiatric comorbidities like depression, anxiety, adjustment disorder, persistent stress, and impaired sexual and marital life.
Aim: The aim of this study was to find out the prevalence of psychiatric comorbidities in patients with psoriasis.
Methods: One hundred and forty-nine consecutive patients with psoriasis fulfilling the inclusion criteria got examined by a senior consultant dermatologist. Sociodemographic and clinical pro forma were filled in. Following informed consent, the patients were assessed for severity of the condition by Psoriasis Area and Severity Index score and were screened for the presence of psychiatric comorbidities by a validated Bengali version of the screening tool Self-Reporting Questionnaire 20 (SRQ 20). Subjects were administrated in succession with Bengali version of Self-Reporting BDI (Beck Depression Inventory) (already validated), Hamilton Anxiety Scale, and SKINDEX 61 (interviewer-rated) for evaluating the depression, anxiety, and psychiatric morbidities under the guidance of a consultant psychiatrist.
Results: In index study, a majority of the subjects (98%) had a mild degree of anxiety symptoms. In BDI, the majority of the subjects had minimal depression, whereas near about two-fifths of the subjects had mild to severe depression. As per SRQ assessment of psychopathology, the majority of subjects (57.71%) had psychiatric disorder. Around two-thirds male and half of the female subjects, respectively, were SRQ positive. On SKINDEX-61, the majority of the subjects responded affirmatively in a decreasing order of frequency in the following domains: embarrassment, discomfort, fear, anger, physical limitation, depression, and cognitive impairment. Severity of psoriasis had a significant positive correlation with depression severity grades and the presence or absence of psychopathology. The index study also revealed that the number of body sites involved in psoriasis had a significant positive correlation with depression severity.
Conclusion: Psoriasis was associated with significant psychiatric comorbidities, and those need to be addressed.
