Correlation of skin-related quality of life with anxiety and depression in chronic dermatoses: A cross-sectional study.

BACKGROUND: Dermatology and psychiatry are two specialties which often have a bearing on each other. Multiple indices have been used to study the quality of life in skin diseases; however, very few studies have correlated these indices with questionnaires of common psychiatric comorbidities like anxiety and depression.

METHODS: The study was conducted in a dermatology out patient department (OPD) of a tertiary care hospital. All patients with chronic dermatological conditions (meeting the inclusion criteria) were included, and each patient was made to fill two questionnaires that are Skindex-29 for skin-related quality of life and Beck Depression Inventory (BDI-II) for depression. They were also assessed for anxiety using the Hamilton Anxiety Scale (HAM-A), which was filled under the supervision of a psychiatrist.

RESULTS: The scores for the common diagnoses were collated and analyzed using SPSS 20.0 software, and the results were tabulated. It was found that both the HAM-A and BDI-II had a moderate positive correlation with the Skindex which was statistically significant. Also, on correlating the individual domains of the Skindex with the HAM-A and BDI, the domain of emotions depicted the best correlation.

CONCLUSION: The study brings to light that a relatively easy to administer quality of life questionnaire can be used as a screening tool to identify psychiatric morbidity and in a busy skin OPD, questions from the emotion domain can only be asked for early referral to a psychiatrist.
