Communication during brief intervention, intention to change, and outcome

Area of Science:

• Addiction Medicine
• Behavioral Psychology
• Public Health

Background:

• Hazardous alcohol consumption is a significant public health issue.
• Brief alcohol interventions (BAI) are commonly used to address hazardous drinking.
• Understanding factors predicting intervention success is crucial for optimizing treatment outcomes.

Purpose of the Study:

• To investigate the association between patients' intention to change alcohol consumption after BAI and subsequent changes in drinking behavior.
• To examine the relationship between patient intention and communication characteristics during BAI.
• To identify predictors of successful alcohol reduction following BAI.

Main Methods:

• A pragmatic randomized controlled trial involving 367 hazardous drinkers attending an Emergency Department.
• Alcohol consumption was assessed at baseline and 12-month follow-up using measures like drinks per week and heavy episodic drinking frequency.
• Communication during BAI was analyzed using the Motivational Interviewing Skill Code (MISC) for a subset of 97 participants.

Main Results:

• Patients expressing an intention to decrease alcohol consumption showed greater reductions in alcohol use and related problems.
• Higher levels of readiness and importance to change were reported by patients intending to decrease consumption.
• Patient-generated change talk, including ambivalence and reasons for change, was more pronounced in those intending to modify their drinking.

Conclusions:

• Patient intention to change following BAI is a significant predictor of improved drinking outcomes at 12 months.
• This intention is linked to patient-driven change talk during the intervention.
• Counselor communication skills, as measured by MISC, did not significantly differentiate outcomes based on patient intention, suggesting patient factors are key.
