Background: Chronic skin diseases such as psoriasis (PSO), atopic dermatitis (AD) and hidradenitis suppurativa (HS) are frequently associated with psychological distress, potentially promoting maladaptive coping mechanisms including addictive behaviours. Despite evidence of higher addiction rates among dermatology patients, comprehensive multicenter data across Europe are lacking. Objectives: To estimate the prevalence and patterns of addictive behaviours among patients with chronic skin diseases in European tertiary dermatology centres and explore associated sociodemographic and clinical factors. Methods: This multicentre cross-sectional study recruited adult patients with PSO, AD, HS, alopecia areata (AA), urticaria, or vitiligo from dermatology departments in 20 European countries. Participants completed a standardized questionnaire assessing sociodemographics, disease characteristics, and addictive behaviours (smoking, alcohol use, drug use, gambling, internet addiction, and eating disorders). Descriptive analyses and multivariate logistic regression were performed. Results: Among 3585 participants (median age 43 years; 51.1% female), the prevalence of addictive behaviours was notable: smoking (25.7%), pathological gambling (4.5%), hazardous drinking (8.8%), alcohol dependence (2.5%), drug use disorders (5.3%), eating disorders (1.8%), and internet addiction (29.7%). Smoking was most common among PSO and HS patients (48.6%), and gambling among AA and vitiligo patients (8.2%). Significant associations included male sex, younger age, single status, higher Dermatology Life Quality Index (DLQI) scores, and regional variation. Discussion: Addictive behaviours are prevalent in dermatology patients and are associated with both sociodemographic and disease-related factors. The DLQI was positively correlated with multiple addictions, suggesting that reduced quality of life may contribute to maladaptive coping. However, due to the absence of a control group, the tertiary care setting, limited center distribution, and unknown response rate, generalizability is restricted. Conclusion: Addiction screening and supportive mental health strategies should be integrated into dermatologic care, particularly for high-risk patients. Population-based studies with control groups are needed to confirm these findings. Unlabelled: WHAT IS THE DISEASE?: Chronic skin diseases such as psoriasis, atopic dermatitis, hidradenitis suppurativa, urticaria, alopecia areata and vitiligo are long‐lasting conditions that can cause visible symptoms, emotional distress and social stigma. Many people with these diseases also experience mental health challenges. Location of the study: This study was carried out in dermatology departments across 20 European countries, involving a large number of hospitals and university centres. Aim of the study: The researchers wanted to find out how common addictive behaviours—such as smoking, gambling, alcohol and drug use, eating disorders and internet addiction—are among people with chronic skin diseases and which factors are linked to them. Methodology: A total of 3585 adults with one of six chronic skin diseases completed a detailed questionnaire about their lifestyle, skin condition and quality of life. The study looked for patterns and associations between these factors and different forms of addiction. Key findings: Addictive behaviours were common: about one in four smoked, one in three showed signs of internet addiction and nearly one in 10 reported risky alcohol use. Men, younger people and those who were single or had a lower quality of life were more likely to have an addiction. Rates also varied between European regions. Conclusions and practical implications: Addictions are frequent among people with chronic skin diseases. Screening for addictive behaviours and offering mental health support should become a routine part of dermatologic care to improve overall well‐being and treatment success.
