Functional exercise capacity is associated with global functioning in patients with alcohol use disorder

Area of Science:

• Clinical Psychology
• Rehabilitation Medicine
• Addiction Psychiatry

Background:

• Alcohol use disorder (AUD) significantly impacts patients' overall functioning.
• Assessing functional exercise capacity is crucial for understanding rehabilitation needs in AUD patients.

Purpose of the Study:

• To investigate the association between the Global Assessment of Functioning (GAF) score and functional exercise capacity in inpatients with AUD.
• To determine predictors of GAF scores and functional exercise capacity in this population.

Main Methods:

• 45 inpatients with AUD completed the 6-minute walk test (6 MWT) for exercise capacity and a standing broad jump for muscle strength.
• Participants also completed various questionnaires, including those assessing GAF scores.
• Statistical analyses, including Pearson correlation and variance analysis, were employed.

Main Results:

• A significant positive correlation was found between GAF scores and 6 MWT performance (r=0.47, p=0.002).
• Illness duration explained 27.9% of the variance in GAF scores.
• GAF scores and muscle strength together explained 50.9% of the variance in 6 MWT scores.

Conclusions:

• Functional exercise capacity, particularly endurance measured by the 6 MWT, is associated with global functioning in AUD inpatients.
• Muscle strength also plays a role in exercise capacity.
• Further research is recommended to explore if enhancing physical function can improve global functioning in individuals with AUD.
