Quality of life and psychiatric morbidity was assessed using Dermatology Life Quality Index (DLQI) questionnaire3 and General Health Questionnaire-28 (GHQ-28

. Demographic questionnaire was developed by researchers based on scientific resources and on the objectives of the study.

The metric properties of the GHQ-28
have been explored in numerous studies [64, 65].
