The Role of Parents in Adolescent Weight Loss

Not Applicable

Completed

• Conditions: Adolescent Obesity
• Interventions: Behavioral: Behavioral Weight Control with Enhanced Parent Involvement; Behavioral: Behavioral Weight Control with Minimal Parent Involvement

• Registration Number: NCT01139411
• Lead Sponsor: The Miriam Hospital

Brief Summary

The purpose of the study is to determine whether a novel model of including parents in adolescent weight control results in greater decrease in adolescent z-BMI compared to an intervention with minimal parent involvement.

Arm && Interventions

Group	Intervention	Description
Behavioral Weight Control with Enhanced Parent Involvement	Behavioral Weight Control with Enhanced Parent Involvement	This treatment arm included periodic dyadic sessions with adolescents and their parents, focusing on weight-related communication combined with standard behavioral weight control.
Behavioral Weight Control with Minimal Parent Involvement	Behavioral Weight Control with Minimal Parent Involvement	This treatment arm included standard behavioral weight control delivered to the adolescent with minimal parent involvement.

Primary Outcome Measures

Name	Time	Method
Body Mass Index	Baseline and at completion of 16 week intervention	Post-treatment BMI (controlling for baseline BMI)

Secondary Outcome Measures

Name	Time	Method
Communication 2: Observed Parent-adolescent Communication Quality (DOCS)	Baseline to post-treatment	Post-treatment value (controlling for baseline). Observed parent-adolescent communication quality was measured using the Dyadic Observed Communication Scale (DOCS) used to code communication between adolescent and caregiver during a video-taped observational coding session. The DOCS is coded on a scale of 0 -10, with higher scores reflecting higher quality of communication, as observed by an independent rater. Higher scores are thought to reflect a better treatment outcome.
Parent Modeling 1: Dietary Choices (WCSS)	Baseline to post-treatment	Post-treatment value (controlling for baseline). Parent modeling of dietary choices was assessed using the Diet Choices subscale of the Weight Control Strategies Scale (WCSS), a parent-report measure of his/her own healthy weight control practices. The Dietary choices subscale of the WCSS has a scale range of 0 - 4, with higher scores corresponding to healthier diet choices. Higher scores are considered to be a better treatment outcome.
Parent Modeling 4: Weight and Body Concerns (FERF-Q)	Baseline to post-treatment	Post-treatment value (controlling for baseline). Parent modeling of concern about weight/body was assessed using the Parent Modeling of Weight and Body Concerns subscale of the Family Experiences Related to Food Questionnaire (FERF-Q)), an adolescent-report measure of parent behavior pertaining to weight control. The Weight and Body Concerns subscale of the FERF-Q has a scale range of 1 - 5, with higher scores corresponding to greater parent weight and body concerns, as perceived and reported by the adolescent. Lower weight and body concern is considered a better treatment outcome.
Parent Modeling 3: Physical Activity (WCSS)	Baseline to post-treatment	Post-treatment value (controlling for baseline). Parent modeling of Physical Activity was assessed using the Physical Activity subscale of the Weight Control Strategies Scale (WCSS), a parent-report measure of his/her own healthy weight control practices. The Physical Activity subscale of the WCSS has a scale range of 0-4, with higher scores corresponding to greater physical activity. Higher scores are considered a better treatment outcome.
Communication 1: Negative Maternal Weight-related Commentary (FERF-Q)	Baseline to post-treatment	Post-treatment value (controlling for baseline). Negative maternal weight-related commentary was assessed using the Negative maternal weight-related commentary subscale of the Family Experiences Related to Food Questionnaire (FERF-Q)), an adolescent-report measure of parent behavior pertaining to weight control. The Negative maternal weight-related commentary subscale of the FERF-Q has a scale range of 1 - 5, with higher scores corresponding to greater negative maternal weight-related commentary, as perceived and reported by the adolescent. Lower scores are considered a better treatment outcome.
Parent Modeling 2: Self-monitoring (WCSS)	Baseline to post-treatment	Post-treatment value (controlling for baseline). Parent modeling of self-monitoring behavior was assessed using the Self Monitoring subscale of the Weight Control Strategies Scale (WCSS), a parent-report measure of his/her own healthy weight control practices. The Self Monitoring subscale of the WCSS has a scale range of 0 - 4, with higher scores corresponding to more self-monitoring behavior. Higher scores are thought to reflect a better treatment outcome.
