Intervention Summary

Collaborative HIV Prevention and Adolescent Mental Health Project (CHAMP) Family Program

The Collaborative HIV Prevention and Adolescent Mental Health Project (CHAMP) Family Program is a 12-week, family-focused, developmentally timed intervention for 4th- and 5th-grade students in urban, low-income communities. CHAMP is guided by a developmentally focused theoretical model informed by an amalgam of prior literature. Briefly, the model posits that at preadolescence, youth are exposed to "situations of sexual possibility" (i.e., unsupervised heterosocial interactions occurring in a private place) but are not yet sexually active, making this age a key intervention target to promote a delay in sexual onset.

The primary goal of CHAMP is to support family processes, specifically family communication, social support, and parental supervision and monitoring skills. The program also is designed to improve child assertiveness and social problem-solving skills. These goals are met through (1) discussion of sexual possibility situations; (2) intensive practice in family communication, making links between family processes and children's participation in sexual possibility situations (in particular, stressing family communication, rule setting, monitoring, support, and discussion of values); and (3) discussion of information relevant to puberty and HIV/AIDS to help prepare families for the coming changes of adolescence. Each program session includes both parent-child joint exercises and breakout sessions for parents and children separately.

The program is delivered through schools as well as by community groups. Local partnerships known as CHAMP Collaborative Boards are highly involved in the development, delivery, and evaluation of the program at each implementation site and include parents, school staff, community-based agency representatives, and university-based researchers. Facilitators receive training before and during implementation but are not required to have any prior specialized training or formal qualifications.

Implementation History In the United States, the intervention has been provided to approximately 570 youth and their families in 5 communities in Chicago and New York City. The program also has been implemented in Argentina, South Africa, and Trinidad and Tobago. With the exception of the program in Argentina, all of the implementations have been evaluated empirically.
NIH Funding/CER Studies Partially/fully funded by National Institutes of Health: Yes
Evaluated in comparative effectiveness research studies: No
Adaptations The CHAMP model has been adapted for the needs of homeless families in HOPE (HIV Prevention Outreach for Parents and Early Adolescents), a family-based HIV and drug abuse prevention program for early adolescent youth and their adult caregivers living in homeless shelters in New York City. The multiple family group delivery strategy used in CHAMP also has been applied in the Multiple Family Group program, which provides mental health services to urban, low-income children of color.

Quality of Research

Documents Reviewed

The documents below were reviewed for Quality of Research. The research point of contact can provide information regarding the studies reviewed and the availability of additional materials, including those from more recent studies that may have been conducted.

Outcomes

Outcome 1: Family communication
Description of Measures In one study, two dimensions of family communication, comfort and frequency, were measured using items adapted from the Family Communication Scale.

In a second study, comfort with communication about AIDS-related issues was measured with a series of questions adapted from the Youth AIDS Prevention Project and the Aban Aya Youth Project. Items address the degree to which youth/caregivers are comfortable with discussing HIV, AIDS, sexuality, and substance abuse. Items are scored on a 4-point scale (from "strongly disagree" to "strongly agree" or "very comfortable" to "uncomfortable").
Key Findings In a study conducted in South Africa, youth and their adult caregivers were randomly assigned by school to the intervention group, which received CHAMP, or to the control group, which received standard school programming. From pre- to posttest, the change in caregivers' comfort with family communication and the frequency of communication was significantly greater among those receiving the intervention (p = .0021 and p = .0412, respectively). These differences were associated with small effect sizes (Cohen's d = 0.4 and 0.2, respectively), based on parameter estimates from mixed-effects regression models.

In a single-group study conducted in the United States, caregivers participating in CHAMP showed a significant pre- to posttest improvement in their comfort with family communication (p < .01).
Studies Measuring Outcome Study 1, Study 2
Study Designs Experimental, Preexperimental
Quality of Research Rating 2.8 (0.0-4.0 scale)
Outcome 2: Knowledge about HIV transmission
Description of Measures Knowledge about HIV transmission was measured with a series of questions adapted from the Youth AIDS Prevention Project and the Aban Aya Youth Project. Items address the degree to which respondents understand how HIV is caused and transmitted. Items are scored on a 3-point scale (as "true," "false," and "not sure").
Key Findings In a study conducted in South Africa, youth and their adult caregivers were randomly assigned by school to the intervention group, which received CHAMP, or to the control group, which received standard school programming. From pre- to posttest, the change in caregivers' knowledge about HIV transmission was significantly greater among those in the intervention group (p = .0084). This difference was associated with a medium effect size (Cohen's d = 0.6), based on parameter estimates from mixed-effects regression models.

In a single-group study conducted in the United States, youth and caregivers participating in CHAMP showed a significant pre- to posttest increase in their knowledge about HIV transmission (p < .01).

Quality of Research Rating 2.7 (0.0-4.0 scale)
Outcome 3: Perceived stigma of HIV/AIDS
Description of Measures Perceived stigma of HIV/AIDS was measured with a series of questions adapted from the Youth AIDS Prevention Project and the Aban Aya Youth Project. Adult and child responses are coded differently, with low scores for adults and high scores for children indicating low levels of perceived stigma.
Key Findings In a study conducted in South Africa, youth and their adult caregivers were randomly assigned by school to the intervention group, which received CHAMP, or to the control group, which received standard school programming. From pre- to posttest, the change in the perceived stigma of HIV was significantly greater among caregivers and youth in the intervention group (p = .0817 and p = .0045, respectively). These differences were associated with small and medium effect sizes (Cohen's d = 0.4 and 0.6, respectively), based on parameter estimates from mixed-effects regression models.
Studies Measuring Outcome Study 1
Study Designs Experimental
Quality of Research Rating 3.1 (0.0-4.0 scale)
Outcome 4: Externalizing behavior
Description of Measures Externalizing behavior among youth participants was assessed using the Child Behavior Checklist (CBC-L/6-18), a widely used 112-item questionnaire in which eight measured characteristics are combined to produce two scales for internalizing and externalizing behavior. The checklist was administered to the parents/caregivers of youth participating in the program.
Key Findings In a single-group study conducted in the United States, youth participating in CHAMPS showed a significant pre- to posttest improvement in externalizing behavior (p < .05).

4: Externalizing behavior 3.8 3.3 2.9 2.0 2.3 2.4 2.8

Study Strengths

Reliability and validity were enhanced by the studies' use of portions of a measure that had prior study-based testing. The investigators made careful efforts to ensure intervention fidelity, both by putting mechanisms in place to train the implementers and by conducting regular follow-ups. Study population sizes were robust, and in two of three studies reviewed, attrition was very low. The most rigorous of the three studies used a quasi-experimental design, which helped to minimize the effects of potential confounding variables.

Study Weaknesses

Attrition in one of the three studies was quite high, approaching 50%. Although the steps taken to maximize intervention fidelity are described in some detail, evidence of the success of these steps is not provided. Two of the studies employed a preexperimental design that did not adequately control for potential confounding factors. Analytical procedures are not described in detail in all the studies reviewed, requiring some inferences to be made about the approach taken.
