Intervention effects in entire sample and among those exposed to IPV or RC at baseline using data pooled from both time points
| Entire Sample | Those reporting recent IPV or RC at baseline | |
|---|---|---|
| Outcome | Intervention Effects | Intervention Effects |
| Poisson Mixed Models | ARR (95% CI)* | ARR (95% CI)* |
| Reproductive coercion† | 1.50 (0.95-2.35) | 1.19 (0.63-2.22) |
| Intimate partner violence† | 1.07 (0.84-1.38) | 1.16 (0.82-1.64) |
| Knowledge of IPV-related resources | 4.25 (3.29-5.50) | 3.48 (1.77-6.86) |
| Logistic / Multinomial Mixed Models | AOR (95% CI)* | AOR (95% CI)* |
| Past-year pregnancy status‡ | ||
| Intended pregnancy | 1.29 (0.70-2.38)§ | 1.44 (0.32-6.47)∥ |
| Unintended pregnancy | 1.03 (0.80-1.33)§ | 1.15 (0.67-1.96)∥ |
| Use of any harm reduction behaviors | 1.25 (0.80-1.94)¶ | 1.06 (0.64-1.78) |
| Use of IPV-related resources | n/a | 1.19 (0.65-2.19) |
| Disclosure to healthcare provider | n/a | 1.16 (0.76-1.79) |
| Linear Mixed Models | AMD (95% CI)* | AMD (95% CI)* |
| Recognition of sexual and reproductive coercion | 0.003 (−0.08-0.08) | −0.02 (−0.12-0.09) |
| Self-efficacy to implement harm reduction behaviors# | 0.06 (0.02-0.10) | −0.001 (−0.13-0.13) |
Adjusted for the centered baseline value of outcome (as applicable), time point, interaction term between baseline outcome value and time point (as applicable), age, race, education, number of clinics in cluster (one versus multiple), and cluster rural/urban status, and accounting for clients within clinics within the cluster randomization
Poisson model included random effects for subjects only because models with clinic effects did not converge numerically
Reference group was no past-year pregnancy
Model also adjusted for baseline report of past-year pregnancy and pregnancy status at baseline
Model adjusted for baseline report of past-year pregnancy and pregnancy status at baseline only due to model nonconvergence
Model not adjusted for covariates due to model nonconvergence
Model also adjusted for baseline value of general self-efficacy
ARR, adjusted risk ratio; CI, confidence interval; IPV, intimate partner violence; AOR, adjusted odds ratio; n/a, not applicable (outcome was not assessed in this sample); AMD, adjusted mean difference ICCs ranged from <.0001 to 0.017 across outcomes for entire sample and <.0001 to 0.058 across outcomes for those reporting recent IPV or RC at baseline
