Evaluation of symptoms of psychological disorders in oral and dermal lichen planus patients referred to Tabriz Sina hospital in the late half of year 1397

Abstract

Introduction: Lichen planus is one of the most common mucosal skin diseases in the world. Due to the importance of this lesion and its high prevalence, several studies have been performed on lichen planus and several risk factors and underlying factors have been introduced for this disease, but its etiology has not been fully understood. Some genetic and environmental factors are involved in the disease. Materials and Methods: In this study, 31 patients with lichen planus were selected from a total number of all patients referred to the dermatology department of Sina Hospital in Tabriz, whose disease was confirmed by biopsy. Additionally, 31 patients without Lichen planus lesions were included as the control group. Data were collected through SCL-90-R standard questionnaire. The results of the study were analyzed by descriptive statistics and statistical analysis with SPSS17 software and p<0.05 was considered statistically significant. The reliability of the questionnaire was measured by Cronbach's alpha coefficient and coefficients above 80% were accepted. Results: Analysis of the participants’ psychologic profile data in both male and female groups, shows that people with Lichen planus have no serious psychological problems and psychiatric problems are mild to moderate. However, the use of t-test indicates that somatization (16 patients), obsessive-compulsive (9 patients), interpersonal sensitivity (12 patients), depression (14 patients), anxiety (14 patients), hostility (10 patients), phobic anxiety (9 patients), paranoid ideation (9 patients) and psychotic (k patients) disorders were significantly higher in patients with oral lichen planus in comparison to control group (9 patients). Conclusion: The results of the SCL-90-R checklist indicate that patients with oral lichen planus have significantly more psychiatric symptoms than normal people and therefore these patients need more psychiatrical investigation.
