Study 1
Graham-Bermann and colleagues (2007) conducted a quasi-experimental, community-based intervention to study the effect of the Mom’s Empowerment and Kids Club programs on battered moms and their children. The study was conducted in five urban locations in Michigan. Mothers who were victims of intimate partner violence (IPV) within the past year and their children, whether they were exposed to IPV or were victims, were eligible and children with diagnosable and non-diagnosable problems were also eligible for the study.
The study involved interviewing 221 mothers and children. The children were randomly assigned to three conditions: 1) child-only intervention (Kids Club), 2) child-mother intervention (Mom’s Empowerment), or 3) the comparison group (CG). The study used a sequential assignment procedure. The first seven children were assigned to child-only (CO). The next seven children were assigned to the child-mother (CM) group, and the following seven were assigned to the comparison group (CG). This assignment method continued until each child was assigned to a group. The CG children were placed on a waiting list and did not participate in either intervention. CM and CO groups did not differ from CG participants in ethnicity, income, maternal age or marital status, education, child age or gender, or exposure to IPV.
There were 62 children in the CO group, 61 children in the CM group, and 58 children in the CG group. All three groups were interviewed at baseline before the program began and interviewed a second time at the end of the program. The CO and CM groups were interviewed a third time, 8 months after the program ended. At the end of the 10 weeks, those in the CG were offered a chance to participate in the program and were not interviewed a third time. Seven children who received the treatment were not interviewed a third time; two refused the interview, and five dropped out after the program ended. This left 56 in the CO group and 60 in the CM group who participated in all three interviews.
Externalizing and internalizing behaviors were assessed, using the Child Behavioral Checklist. Mothers completed this 113-item questionnaire, rating statements about behaviors in their child from a score of 0 to 2, with 0 meaning “not true,” 1 meaning “somewhat or sometimes true,” and 2 meaning “very true or often true.” The Externalizing Scale has statements about aggression and delinquency, while the Internalizing Scale has statements about anxiety, depression, withdrawal, and somatic complaints.
Attitudes toward violence were also assessed, using the Attitudes About Family Violence Scale, an instrument that was created for use in this study. The child was asked to rate 10 statements about violence on a 5-point scale about how much they agreed with the statement. Positive statements were reverse scored, so that the higher the overall score, the more negative the attitude toward violence. There were no subgroup analyses conducted.
The focus of this review was the impact of the Mom’s Empowerment program on the CM group, compared with the CG group.
Study 2
Miller, Howell, and Graham-Bermann (2014) conducted a randomized controlled trial to study the effect of Mom’s Empowerment Program on mothers impacted by intimate partner violence (IPV). The study included women from urban and rural areas in the midwestern United States and in southern Ontario, Canada. Women were eligible to participate if they experienced IPV within the past 2 years and had a child between 4 and 6 years old.
The study involved baseline interviews with 120 women. The women ranged in age from 21 to 54 years. Of the total sample, 48 percent were white, 37 percent were African American, 8 percent were biracial, 6 percent were Hispanic American, and 1 percent were Asian American. Most women had some college or advanced education (59 percent), but were generally low income. Women who were interested in participating in the intervention were randomly assigned to the treatment group (Mom’s Empowerment) or to the comparison group after their baseline interview.
The comparison group consisted of 62 women, and the treatment group consisted of 58 women. Comparison group participants were offered the opportunity to participate in the intervention after the second interview. Also, at the 6- to 8-month mark, baseline interviews were conducted with the treatment group before the first program session and a second interview was conducted at the end of the program (approximately 5 weeks later). The comparison group was also interviewed at baseline and approximately 5 weeks later. Follow-up interviews took place for both groups approximately 6 to 8 months after the second interview. After the second interview, women in the comparison group were given the opportunity to participate in the program. Nine women opted to join the program; however, because this participation could have contaminated the follow-up data, the nine women were not included in the final analysis. In addition, at the follow up, 41 percent of the women were unable to be located; therefore, the total sample size at follow up was only 62 women for both groups.
A Conflict Tactics Scale-Revised Version (CTS2) was used to measure exposure to violence. Women reported the number of times they were victims of a particular violent offense during their baseline interview and again at their 6- to 8-month follow up. The study used an intent-to-treat approach analysis. There were no subgroup analyses conducted.
