Overview
Brief Summary
This study evaluates the impact of adaptive technology-based intervention (online, text and phone) "weWomenPlus" on safety, mental health and empowerment of abused immigrant women.
Detailed Description
Intimate partner violence (IPV) disproportionately affects immigrant women. However, immigrant women remain an understudied and underserved population in need for evidence-based rigorously evaluated culturally competent interventions that address the health and safety needs of immigrant women. This study used a sequential, multiple assignment, randomized trial (SMART) design to rigorously evaluate an adaptive culturally informed intervention tailored to needs of immigrant women with IPV experiences. For the first stage randomization, participants were randomly assigned to a personalized online intervention or the standard online safety information/usual care control arm and safety, mental health and empowerment outcomes were assessed at 3, 6 and 12 months follow up. For the second stage randomization, women who did not report significant improvement in safety (i.e., reduction in IPV) and in empowerment from baseline to follow up points (i.e., non-responders) were re- randomized to the augmented intervention components (text only or a combination of text and phone) developed in the formative phase. Data on outcomes (safety, mental health and empowerment) were assessed at 6 and 12 months of re- randomization. By re-randomizing participants, the study assessed the relative effectiveness of two strategies for augmentation (text only or a combination of text and phone) on safety, mental health and empowerment outcomes among the non-responders of the online interventions. In addition, the study compared the non-responder group of women to the responder group of the online interventions to determine if the strategies of augmentation brought the non-responders to the level of responders on safety, mental health and empowerment.

Outcomes
Primary Outcomes
Change in Severity of Physical and Sexual Intimate Partner Violence as Assessed by the Revised Conflict Tactics Scale
Time Frame: Baseline (1st month), 3 months, 6 months, 12 months
The adapted version of the Revised Conflict Tactics Scale (CTS2; Straus, 1996) was used to measure the severity and frequency of abusive or violent acts in intimate partner relationships. The CTS2 subscales included physical aggression, injury, psychological aggression, and sexual coercion. Response categories ranged from 0=never to 4=very frequently. Total scores ranged from 0-164, with higher scores indicating greater frequency and severity of intimate partner violence experiences. Items were scored using the severity-times-frequency weighted score method as recommended by Straus (1996). Change scores were calculated as the differences between baseline CTS-2 total scores and follow-up scores at each time point (3, 6, and 12 months).
Secondary Outcomes
- Change in Depressive Symptoms as Assessed by the Patient Health Questionnaire (PHQ-9)(Baseline, 3 months, 6 months, 12 months)
- Change in Symptoms of Post-traumatic Stress Disorder (PTSD) as Assessed by the Harvard Trauma Questionnaire(Baseline, 3 months, 6 months, 12 months)
- Change in Overall Empowerment as Assessed by the Personal Progress Scale-Revised(Baseline, 3 months, 6 months, 12 months)
- Change in Empowerment Related to Safety as Assessed by the Measure of Victim Empowerment Related to Safety (MOVERS) Scale(Baseline, 3 months, 6 months, 12 months)
