The effects of multisystemic therapy on family support for weight loss among obese African-American adolescents: findings from a randomized controlled trial.

OBJECTIVE: To determine whether multisystemic therapy, an intensive, home- and community-based intervention, could increase family support for healthy eating and exercise in obese African-American adolescents. Relationships between changes in family support, weight status, and body fat composition at the end of the trial were also evaluated. METHOD: A pilot randomized clinical trial was conducted with 49 obese adolescents (body mass index > or = 95th %ile). Participants were randomized to receive multisystemic therapy or Shapedown, a group weight loss intervention. Participants received treatment for 6 months. Data were collected at baseline and 7-month posttest (i.e., treatment termination). Changes in family support for healthy eating and exercise were assessed by self-report questionnaire. Bivariate analyses were used to assess the relationship between change in family support during the trial and youth body mass index, percent overweight, and body fat composition at follow-up. RESULTS: Participation in multisystemic therapy was associated with significantly greater improvements in family encouragement for healthy eating and family participation in exercise and greater decreases in discouraging behavior from family members than Shapedown participation. Increases in family participation in exercise were significantly related to lower youth body mass index, percent overweight, and body fat composition at follow-up. CONCLUSIONS: Intensive, home- and community-based treatment increased family support for health behavior changes among obese minority adolescents, and these changes were directly related to weight status. Such health improvements are important for the well-being of a subset of youth who are at high risk for future health complications.

A multisite randomized trial of a motivational intervention targeting multiple risks in youth living with HIV: initial effects on motivation, self-efficacy, and depression.

PURPOSE: Interventions targeting multiple risk behaviors are needed for youth living with HIV (YLH). A randomized clinical trial compared Healthy Choices, a four session motivational intervention targeting two of the three risk behaviors (HIV medication adherence, sexual risk behavior and substance use) to multidisciplinary specialty care alone. This article presents intermediary outcomes available at 3-month follow-up, variables proposed to be precursors to behavior change (motivation, self-efficacy, and depression). METHODS: YLH (N=186) with at least one of the three problem behaviors were recruited from four sites in the Adolescent Trials Network and one non-Adolescent Trials Network site, and were assessed at baseline and 3 months. RESULTS: Of the 94 youth randomly assigned to the treatment condition, 84% received at least one session, 67% received at least two sessions, 56% received at least three sessions, and 49% completed all four sessions. In intent-to-treat analysis, only depression was significantly improved in the treatment group as compared with controls. However, in per-protocol analysis, youth receiving at least two sessions of the intervention also showed significant improvements in motivational readiness to change as compared with youth in the control condition. CONCLUSION: Results suggest the potential benefits of clinic-based motivational interventions for YLH who access these interventions. Delivering interventions in the community using an outreach model may improve access. Analysis of subsequent time points will determine effects on actual behavior change.

Psychosocial factors and substance use in high-risk youth living with HIV: a multi-site study.

The purpose of the study was to test relationships between psychosocial factors and alcohol and illicit drug use among high-risk youth living with HIV (YLH). One hundred eighty-six high-risk youth with HIV (defined as those with a substance use problem, sexual risk problem, or medication adherence problem) were enrolled across five cities (ages 16-24). Alcohol and illicit drug use were measured with the alcohol, smoking, and substance involvement screening test and a timeline follow-back interview. Questionnaires assessed constructs from the adapted Transtheoretical Model (TTM) including a continuous measure of motivational readiness in response to criticisms of the stage component. Path analysis was utilized to fit cross-sectional data collected via computer assisted personal interviewing (baseline data from intervention study). Separate models were fit for each commonly used substance. In the previous month, 47% used alcohol, 37% used cannabis, and 9% used other illicit drugs. Path models fit the data well and accounted for 30% of the variance in alcohol use and 47% in cannabis use. Higher self-efficacy predicted lower alcohol and cannabis use, but motivational readiness was only directly related to cannabis use. A reduction in pros of substance use was indirectly related to use. Social support and psychological distress were associated with TTM constructs. Interventions focusing on improving motivation and self-efficacy for healthy behaviors may reduce substance use in YLH.

The effects of parental depression and parenting practices on depressive symptoms and metabolic control in urban youth with insulin dependent diabetes.

OBJECTIVE: Examine relationships between parental depressive symptoms, affective and instrumental parenting practices, youth depressive symptoms and glycemic control in a diverse, urban sample of adolescents with diabetes. METHODS: Sixty-one parents and youth aged 10-17 completed self-report questionnaires. HbA1c assays were obtained to assess metabolic control. Path analysis was used to test a model where parenting variables mediated the relationship between parental and youth depressive symptoms and had effects on metabolic control. RESULTS: Parental depressive symptoms had a significant indirect effect on youth depressive symptoms through parental involvement. Youth depressive symptoms were significantly related to metabolic control. While instrumental aspects of parenting such as monitoring or discipline were unrelated to youth depressive symptoms, parental depression had a significant indirect effect on metabolic control through parental monitoring. CONCLUSIONS: The presence of parental depressive symptoms influences both youth depression and poor metabolic control through problematic parenting practices such as low involvement and monitoring.

A randomized pilot study of multisystemic therapy targeting obesity in African-American adolescents.

Adolescents with obesity (N = 48) and their caregivers were randomized to Multisystemic Therapy (MST) or a group weight-loss intervention. MST adolescents significantly reduced percents overweight and body fat, while control adolescents did not. Treatments such as MST that can intervene in the multiple systems that influence weight are worthy of further study.
