Outcomes
Outcome 1: HIV sexual risk behaviors |
Description of Measures
|
Analyses for HIV sexual risk behaviors were based on women who reported at posttest that they had sex with a main partner in the past 3 months. Focus was given to sex with the main partner because very few women reported having had sex other than with their main partner.
At baseline and posttest, women were asked how many times within the past 3 months they had vaginal sex with their main partner and how many times they or their partner had "used a condom from start to finish." For each 3-month period, the number of times condoms were used was divided by the number of occasions of vaginal sex, yielding a percentage measure of condom use. A score of "1," indicating a reduction in HIV sexual risk behaviors, was assigned if any of the following applied:
- The percentage of condom use was 100% at both baseline and posttest.
- The percentage of condom use increased from baseline to posttest.
- Any condom use was reported at posttest, and the woman reported at baseline that she was either sexually abstinent or sexually active with zero condom use.
All other patterns of condom use or nonuse were scored "0," indicating no reduction in HIV sexual risk behaviors.

Key Findings
|
HIV-positive women with a history of child sexual abuse were randomly assigned to the intervention or an attention control condition. Women in the intervention group participated in HOW sessions and received case management support through weekly phone calls. Women in the control group also received weekly calls from case managers, attended one group meeting in which they received information on HIV prevention and child sexual abuse, and were wait-listed for the intervention. All women were offered additional services, including child care, food, housing, referrals for medical, legal, and dental care, and referrals for psychological counseling.
At posttest, women in the intervention group were about 1.5 times more likely to report reduced HIV sexual risk behaviors (i.e., increased condom use, 100% condom use, or regular condom use after initiating sexual activity following periods of abstinence) compared with women in the control group (odds ratio = 2.96, p = .039, one-tailed). The analysis used an intent-to-treat model and adjusted for covariates.

Outcome 2: HIV medication adherence |
Description of Measures
|
HIV medication adherence was assessed by asking women at posttest how many days in the past 2 weeks they had taken their HIV medication "exactly as prescribed (on schedule and the correct dose)." Those reporting adherence on all 14 days were scored "1." All other women received a medication adherence score of "0." Women with no current prescription for HIV medication were omitted from the analysis.

Key Findings
|
HIV-positive women with a history of child sexual abuse were randomly assigned to the intervention or an attention control condition. Women in the intervention group participated in HOW sessions and received case management support through weekly phone calls. Women in the control group also received weekly calls from case managers, attended one group meeting in which they received information on HIV prevention and child sexual abuse, and were wait-listed for the intervention. All women were offered additional services, including child care, food, housing, referrals for medical, legal, and dental care, and referrals for psychological counseling.
At posttest, women in the intervention group who attended at least eight intervention sessions reported higher medication adherence compared with those attending seven or fewer sessions (p = .044, one-tailed) and women in the control group (p = .0128). The analysis used an intent-to-treat model and adjusted for covariates.

Outcome 3: Posttraumatic stress disorder (PTSD) symptoms |
Description of Measures
|
Symptoms of PTSD were assessed using the PTSD diagnostic module of the University of Michigan version of the Composite International Diagnostic Interview (UM-CIDI). Women first answered a series of questions about past sexual experiences to identify potentially traumatic sexual experiences or instances of sexual abuse. They were then asked 16 questions about the impact the event(s) may have had on them, such as:
- "Did you keep remembering any of the events when you did not want to?"
- "Did you keep having dreams or nightmares about them afterward?"
- "Did you get very upset when you were in a situation that reminded you of any of these events?"
At baseline, posttest, and 3-month follow-up, women reported if these symptoms had occurred at any time since the event(s); at 6-month follow-up, they reported symptoms in the past 3 months. "Yes" responses were coded "1," and "no" responses were coded "0." "Yes" responses were totaled to yield a PTSD symptoms score.

Key Findings
|
HIV-positive women with a history of child sexual abuse were randomly assigned to the intervention or an attention control condition. Women in the intervention group participated in HOW sessions and received case management support through weekly phone calls. Women in the control group also received weekly calls from case managers, attended one group meeting in which they received information on HIV prevention and child sexual abuse, and were wait-listed for the intervention. All women were offered additional services, including child care, food, housing, referrals for medical, legal, and dental care, and referrals for psychological counseling.
Women in the control group had the option to enroll in the intervention after completing the posttest assessment. Just over one third opted to enroll as a delayed intervention group, while the remainder continued in the control condition.
At their respective posttest assessments, both intervention groups reported greater reductions in PTSD symptoms compared with the control group, although the control group also showed a reduction in symptoms (p < .05). This finding is associated with a medium effect size (eta-squared = .11).
At 6-month follow-up, both intervention groups continued to show greater reductions in PTSD symptoms relative to the control group, with the immediate intervention group showing the fastest reduction in symptoms (p < .05).

Study Strengths The measure used to assess PTSD symptoms has well-documented validity and interrater and test-retest reliability. Internal consistency for this measure was high in the study reviewed. The measures used to assess HIV sexual risk reduction and HIV medication adherence had adequate internal consistency in this study as well as face validity. Several strategies were used to ensure accurate data reporting, including repeating critical questions and using a scale to test for social desirability in participants' self-reporting. Implementer training was provided, although its duration varied across staff members. Fidelity was assessed by supervisors using a curriculum observation form and fidelity checklist at each session, with very high fidelity reported. Interrater agreement was .96. A training manual was created and provided to all staff members; as well as frequent supervision sessions. Missing data and attrition were low. Level of education was related to study attrition and was included as a covariate. Random assignment of participants to study condition was used for two of the three outcomes reviewed, HIV sexual risk reduction and HIV medication adherence. The analysis approach followed an intent-to-treat methodology. Use of multivariate modeling was appropriate. Power analysis was conducted.
Study Weaknesses Attrition differed between study groups. There were several potential confounding variables. Differential time with a counselor may have contributed to group differences. The observed dose-response finding for HIV medication adherence may have been confounded by other, unmeasured variables. For example, it is possible that those participants who completed more sessions were different from those who completed fewer sessions (e.g., less severe symptoms, more conscientious, less hectic lives, more free time) which also allowed them to adhere better to their medication regimen. The investigators appear to have overfit the analytic models by including all possible covariates without providing sufficient justification, especially given a relatively small sample size. Analyses of HIV sexual risk reduction and HIV medication adherence used a one-tailed test of significance, which tends to inflate the probability of a Type I error.
