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.
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.

Change in Severity of Physical and Sexual Intimate Partner Violence as Assessed by the Revised Conflict Tactics Scale
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).
Time frame: Baseline (1st month), 3 months, 6 months, 12 months
Change in Depressive Symptoms as Assessed by the Patient Health Questionnaire (PHQ-9)
The Patient Health Questionnaire (PHQ-9) was used to assess depression symptoms over the past two weeks based on DSM-IV diagnostic criteria for major depressive disorder. Each of the 9 items was scored from 0 (not at all) to 3 (nearly every day). Total scores were computed by summing all items, ranging from 0-27. Higher scores indicated more severe depression symptoms (1-4=minimal, 5-9=mild, 10-14=moderate, 15-19=moderately severe, 20-27=severe depression). Change scores were calculated as the differences between baseline PHQ-9 total scores and follow-up scores at each time point (3, 6, and 12 months).
Time frame: Baseline, 3 months, 6 months, 12 months
Change in Symptoms of Post-traumatic Stress Disorder (PTSD) as Assessed by the Harvard Trauma Questionnaire
Past week PTSD symptoms were measured using the Harvard Trauma Questionnaire, a 16-item scale with response options that ranged from 1 (not at all) to 5 (extremely). Mean scores across all 16 items were calculated for each participant. Higher scores indicated more severe PTSD symptoms, with scores greater than 2.5 indicating clinically significant PTSD symptoms. Change scores were calculated as the differences between baseline mean scores and the follow-up mean scores at each time point (3, 6, and 12 months).

Change in Overall Empowerment as Assessed by the Personal Progress Scale-Revised
The Personal Progress Scale-Revised was used to measure empowerment across multiple domains including positive self-evaluation, self-esteem, emotional regulation, gender-role and cultural identity awareness, self-efficacy, self-care, problem-solving, and assertiveness skills. Participants rated 28 items on a 7-point scale from 1 (almost never) to 7 (almost always). Total scores were calculated by summing all items, ranging from 28-196, with higher scores indicating greater empowerment. Change scores were calculated as the differences between baseline total scores and follow-up scores at each time point (3, 6, and 12 months).
Time frame: 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
The MOVERS scale was used to measure empowerment within the safety domain, including safety-related goal development, self-efficacy beliefs, and knowledge of support resources. Participants rated 13 items on a 5-point scale from 1 (never true) to 5 (always true). Mean scores across all 13 items were calculated for each participant. Higher scores indicated greater safety-related empowerment. Change scores were calculated as the differences between baseline mean scores and follow-up mean scores at each time point (3, 6, and 12 months).
