Study summary

The purpose of this study is to investigate the effects of an acceptance-based therapy weight loss intervention compared with enhanced care for adolescents.

Read the detailed description

Participants will complete baseline assessments and adolescents will be randomized to either an ABT weight loss intervention or enhanced care.

The intervention will include 15 sessions over 6 months. Enhanced care will include 15 healthy lifestyle handouts over 6 months.

Post-treatment assessments will occur.

Study arms

  • Experimental
    ABT Weight Loss Intervention

    Adolescent participants will attend sessions that include nutritional education and physical activity education and build skills in the areas of values clarification, mindfulness, self-regulation skills, acceptance of uncomfortable states, goal-setting, problem solving, and self-monitoring.

    Behavioral: ABT Weight Loss Intervention

  • Placebo comparator
    Enhanced Care

    Adolescent participants will receive handouts on elements of a healthy lifestyle and will participate in a midpoint one-on-one nutrition consultation with a registered dietitian.

    Other: Enhanced Care

Interventions

  • BehavioralABT Weight Loss Intervention

    This includes 15 sessions that are each 90 minutes in length. Intervention sessions will be weekly for the first 2 months, bi-weekly for the next 2 months, and monthly for the last 2 months.

  • OtherEnhanced Care

    This includes 15 handouts on elements of a healthy lifestyle and a midpoint one-on-one nutrition consultation with a registered dietitian.

What researchers measure

Primary outcomes

  1. BMI Change, 95th BMI Percentile (%)

    Changes in weight relative to the BMI at the 95th percentile based on sex-and-age (as a difference in percentage units and/or a difference in BMI units) will be evaluated.

    Time frame: Baseline; Month 6

Secondary outcomes

  1. Change in Quality of Life

    Measurements of quality of life (using the valid Pediatric Quality of Life Inventory assessment: scores 0-100) will be conducted. Higher scores indicate better health-related quality of life.

    Time frame: Baseline; Month 6

  2. Change in Depression Using the Valid Beck Depression Inventory-II

    Depression is measured with the Beck Depression Inventory- II (BDI-II). The BDI-II measures the severity of depression. Each item is assessed on a 4-point ordinal categorical scale (0-3 points) that is specific to the question subject matter being addressed (e.g. sadness, self-criticalness, loss of pleasure, etc), and then answer choices are summed to generate a total score. The BDI-II is reliable and valid in an adolescent population. Participants receive a sum-score (ranging from 0-63), which correlates with a certain classification and level of depression. Scores 1-10 (normal ups and downs) and 11-16 (mild mood disturbance) are classified as low. Scores 17-20 (borderline clinical depression) and 21-30 (moderate depression) are classified as moderate. Scores 31-40 (severe depression) and 40+ (extreme depression) are classified as significant.

    Time frame: Baseline; Month 6

  3. Change in Anxiety-sensitivity Using the Valid Short Scale Anxiety Sensitivity Index Assessment

    Measurements of anxiety-sensitivity (using the valid Short Scale Anxiety Sensitivity Index-3 assessment: scores 0-20) will be conducted. Higher scores indicate higher anxiety-sensitivity.

    Time frame: Baseline; Month 6
