Role of Personality and Self-esteem in Acne Vulgaris: A Case–control Study from Southern India

Introduction: Acne vulgaris is a chronic inflammatory skin condition characterized by comedones, papules, pustules, and nodules in various parts such as the face, chest, and back. Acne vulgaris also is associated with depression, anxiety, and disability. Patients with acne could have significant psychological consequences such as decreased self-esteem and impaired quality of life. They are also observed to develop personality traits and disorders. This study aims to study the personality traits and self-esteem among patients with acne. Methodology: This is a case–control study that included 100 patients with acne who are aged 18–45 years. One hundred sex- and age-matched controls were also included in the study. Acne was graded depending on severity, considering the predominant lesions, and personality was assessed using the Eysenck Personality Inventory. Self-esteem was assessed using the Rosenberg Self-esteem Scale (RSES). Past histories of psychiatric disorders, pregnancy, lactation, mental retardation, and acne-worsening drugs were excluded from the study. Results: Acne was predominant in female gender (69%). Face was the most commonly involved area (82%), and papules were the most prevalent lesion type (64%). The mean RSES score was higher in controls (19.74 ± 4.23) than in cases (15.72 ± 5.06). The mean neuroticism scores were higher in cases (17.12 ± 3.048), as compared to controls (7.30 ± 2.418). The mean extraversion scores were lower in cases (13.80 ± 3.149) when compared to controls (15.46 ± 2.984). Conclusion: Acne patients had significantly higher neuroticism and lower extraversion compared to controls. Self-esteem scores were lower in acne patients.
