Table 2 Results of Monte Carlo simulation analyses examining power to detect aim 1 and aim 2 outcome effects
Outcome | Comparison (n per condition) | Predicted rates/effects | Power at α = .05 |
|---|---|---|---|
Aim 1 | |||
 Reacha | Usual care (720)–preparation/implementation (480) | 2–22% | 98% |
 Adoptionb | Usual care (70)–preparation/implementation (70) | 10–50% | 95% |
 Implementation | No comparison |  |  |
 Maintenance | Preparation/implementation (480)–sustainment (1200) |  |  |
Aim 2 | |||
 Stimulant abstinence | Usual care (720)–preparation/implementation (480) | 25–40% | 90% |
 Treatment retention | Usual care (720)–preparation/implementation (480) | 9 weeks–12 weeks | 94% |
