Hypothesis
What factors make it more likely that substance abuse treatment units will add new community prevention, education, and outreach services?
Conclusion
Substance abuse treatment units in more affluent communities are more likely to add prevention-related education and outreach services.
Supporting Evidence
- Units in higher income areas had 5% higher odds of adding prevention services for every $1,000 increase in income.
- Managed care contracts were associated with a 42% reduction in the odds of adding prevention services.
- No hospital-affiliated units added prevention services during the study period.
Takeaway
This study found that treatment centers in richer areas are more likely to offer prevention services, and that having managed care contracts can make them less likely to do so.
Methodology
The study used a lagged cross-sectional logistic model to analyze data from a national survey of outpatient substance abuse treatment units.
Potential Biases
The study may have Type I errors due to the large number of associations tested.
Limitations
The sample is not nationally representative due to changes in the population of treatment providers after 1995.
Participant Demographics
The study focused on outpatient substance abuse treatment units across the United States.
