Statistical Analysis
UC, Depression, drinking behaviors
We conducted descriptive analyses to compare those in the control group (those receiving usual care), PTSC group (intervention), and Intent-to-Treat (ITT, assigned to PTSC but did not participate in the intervention sessions) groups. Using unequal variance There were some missing values for the control variables, including age, marital status, education, income, health insurance coverage, smoking, and drinking behaviors; we cite the percentage of missing values for these variables in Table Distribution of Characteristics Among PTSC-RCT Participants at Baseline for the Balanced Sample, 2017–2018GED: general education development, PTSC: Prime Time Sister Circles, ITT: Intent-to-Treat, SD: Standard Deviation. 1) Abbreviations: CES-D, Center for Epidemiologic Studies Depression Scale; GED, general education development. PTSC-RCT, Prime Time Sister Circles randomized control trial. 2) We ran unequal t-tests and chi-sq to test the means between control and PTSC groups and UC and ITT groups. 3) We found no significant differences using unequal variance t-tests and Chi-Squared tests between UC and PTSC, ITT and PTSC groups, and US and ITTFor the Intent-to-Treat analysis, we used balanced panel data for women who participated in all 3 rounds of data collection. We included PTSC and ITT (participants initially assigned to PTSC regardless of whether they received the PTSC treatment) and control. The analytical sample of this analysis was 172 participants (516 observations). We also conducted a Per-Protocol analysis. To do so, we repeated the ITT analysis by excluding those assigned to the intervention group who did not receive the treatment (Intent-to-Treat), which reduced the sample to 140 participants (420 observations). This study was approved by the Institutional Review Boards (IRBs) of the Johns Hopkins Bloomberg School of Public Health (JHBSPH) and the American Institutes for Research (JHBSPH IRB No. 00007121).
