Summary
This study found that hazardous alcohol use in individuals with skin picking disorder is linked to greater severity and impairment, alongside higher rates of comorbid conditions. Screening for alcohol problems is crucial for effective treatment.
Area of Science:
- Psychiatry
- Addiction Medicine
- Dermatology
Background:
- Skin picking disorder involves repetitive skin excoriation.
- While linked to substance use, alcohol's specific impact on skin picking symptoms is understudied.
Purpose of the Study:
- To investigate the association between alcohol use and skin picking disorder symptomatology.
- To examine how hazardous alcohol use relates to clinical profiles in individuals with skin picking disorder.
Main Methods:
- 182 adults with skin picking disorder completed online surveys.
- The Alcohol Use Disorders Identification Test (AUDIT) measured alcohol use.
- Comparisons were made between hazardous drinkers (AUDIT ≥8) and low-risk drinkers.
Main Results:
- 34.1% of participants reported hazardous alcohol use.
- Hazardous drinking correlated with increased picking-related severity, impairment, aggression, and comorbidities (e.g., BPD, gambling disorder).
- Skin picking impairment predicted hazardous drinking levels, controlling for sex.
Conclusions:
- Screening for hazardous alcohol use is recommended for individuals with skin picking disorder.
- Further research is needed on the interplay of aggression, alcohol use, and skin picking, and tailored treatment approaches.

993
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Stress often leads to unhealthy habits like smoking, excessive drinking, and overeating, which offer short-term relief but ultimately increase long-term health risks. These behaviors create a cycle that temporarily lowers stress levels but can result in severe long-term health consequences. Breaking these habits is essential to reduce the risk of chronic diseases and improve overall well-being. Three primary changes that support better health include quitting smoking, reducing alcohol intake,...
