Acne vulgaris is a chronic inflammatory skin condition that primarily affects the face, affecting a person's physical appearance. Anxiety, depression, and body dysmorphic disorder (BDD) are the three primary psychological conditions seen in dermatological patients. This study aimed to assess how prevalent anxiety, depression, and BDD in acne patients and the negative effect of acne on quality of life and self-esteem in dermatology patients. This cross-sectional study was done at the dermatology clinic in East Jeddah Hospital, Jeddah, Saudi Arabia. Data was collected using two pre-designed questionnaires. Part 1 contained demographic information and part 2 included four sets of questionnaires including the dermatology life quality index (DLQI), Rosenberg Self-Esteem Scale (RSES), Hospital Anxiety and Depression Scale (HADS), and Body Dysmorphic Disorder Questionnaire (BDDQ). Post-acne hyperpigmentation index (PAHPI), globalscale for acne scar severity (SCAR-S), and LEEDS were used by the dermatologist to assess the patients' acne severity, post-acne scars, and pigmentation conditions. Data were analyzed using the IBM SPSS Statistics for Windows, Version 26 (Released 2019; IBM Corp., Armonk, New York, United States). The majority of the participants were females (76%), Saudi Arabians (95%), students (58%), single (82%), and attended university (66%). The mean acne duration was 5.75 ± 4.58 years and 44% of the participants used social media for more than five hours per day. The participants scored high on the RSES (27.54 ± 3.05), indicating normal self-esteem. The HADS-A score was 11.14 ± 2.74, whereas the HADS-D score was 11.46 ± 1.78, indicating anxiety and depression symptoms. Their mean SCAR-S score is 4.38 ± 2.89. DLQI scores (6.04 ± 6.05) indicate that acne had a moderate effect on patients' quality of life. The percentage of positive BDD patients is significantly higher than those with negative BDD (p = 0.022). Furthermore, a significant association between PAHPI total score and SCAR-S (r = 0.48, p ≤ 0.001) and HADS-D (r = 0.39, p = 0.005) total scores. The study focuses on how acne vulgaris affects patients' quality of life. The findings suggest that acne-related quality of life is positively associated with anxiety and depressive symptoms. This study provides clinicians with practical advice for implementing a more thorough management strategy for acne vulgaris.
