Change talk sequence during brief motivational intervention, towards or away from drinking

Area of Science:

• Addiction research
• Behavioral psychology
• Public health interventions

Background:

• Brief motivational interventions (BMI) are used to address at-risk drinking.
• Understanding the dynamics of 'change talk' within BMI is crucial for improving effectiveness.
• Patient attitudes towards change can fluctuate during interventions.

Purpose of the Study:

• To examine the association between sequences of 'change talk' during BMI and subsequent drinking outcomes.
• To determine if the timing and direction of attitude shifts influence drinking behavior.
• To identify critical points in BMI that predict long-term drinking behavior.

Main Methods:

• Speech content analysis of recorded BMIs using the Motivational Interviewing Skill Code (MISC).
• Application of a Hidden Markov Model to classify patient states (towards change, away from change, non-determined).
• Regression models to predict 12-month drinking outcomes based on patient attitudes at different intervention stages.

Main Results:

• Patient attitudes remained largely stable throughout the BMI, with transitions being less common than stability.
• When attitude shifts occurred, they were more likely to move from an 'away from change' to a 'towards change' state.
• Clients expressing a 'towards change' attitude at the end of the BMI reported significantly lower weekly alcohol consumption at 12-month follow-up.

Conclusions:

• Shifts between 'away from change' and 'towards change' talk are infrequent in BMIs for excessive alcohol consumption.
• A 'towards change' attitude at the conclusion of a BMI is a significant predictor of reduced drinking, irrespective of the initial attitude.
• Ending BMI sessions with clients in a 'towards change' state is a key target for improving intervention outcomes.
