Summary
This study validates the Readiness to Change Questionnaire for excessive drinkers. Stage of change significantly predicts reduced alcohol consumption at 8 weeks and 6 months.
Area of Science:
- Addiction research
- Clinical psychology
- Health behavior change
Background:
- The Readiness to Change Questionnaire (RCQ) is a tool to assess an individual's stage of change regarding problematic behaviors.
- Assessing readiness to change is crucial for tailoring interventions for excessive alcohol consumption.
Purpose of the Study:
- To evaluate the predictive validity of the RCQ in a sample of male excessive drinkers.
- To determine if the 'stage of change' measured by the RCQ predicts changes in drinking behavior over time.
Main Methods:
- A sample of 174 male excessive drinkers was recruited from general hospital wards.
- Patients completed the RCQ prior to hospital discharge.
- Drinking behavior was assessed at 8 weeks and 6 months follow-up.
- Statistical analysis, including multiple regression, was used to analyze the relationship between stage of change and drinking outcomes.
Main Results:
- The allocated stage of change from the RCQ showed statistically significant relationships with drinking outcomes.
- Stage of change remained a significant predictor of reduced alcohol consumption, even when other potential predictors were controlled for in multiple regression analysis.
Conclusions:
- The Readiness to Change Questionnaire demonstrates predictive validity for changes in drinking behavior among male excessive drinkers.
- The 'stage of change' is a valuable predictor for intervention effectiveness in managing alcohol consumption.
- Two methods for allocating stage of change ('quick' and 'refined') are presented for practical application.
