Problematic Internet Use Excessive Alcohol Consumption Their Comorbidity and Cardiovascular and Cortisol Reactions to Acute Psychological Stress in a Student Population

摘要

Background and AimsProblematic Internet use and excessive alcohol consumption have been associated with a host of maladaptive outcomes. Further, low (blunted) cardiovascular and stress hormone (e.g. cortisol) reactions to acute psychological stress are a feature of individuals with a range of adverse health and behavioural characteristics, including dependencies such as tobacco and alcohol addiction. The present study extended this research by examining whether behavioural dependencies, namely problematic Internet use, excessive alcohol consumption, and their comorbidity would also be associated with blunted stress reactivity.
