What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Body Mass Index

    Post-treatment BMI (controlling for baseline BMI)

    Measured: Baseline and at completion of 16 week intervention

Secondary outcomes (6)
  1. Parent Modeling 1: Dietary Choices (WCSS)

    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.

    Measured: Baseline to post-treatment

  2. Parent Modeling 2: Self-monitoring (WCSS)

    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.

    Measured: Baseline to post-treatment

  3. Parent Modeling 3: Physical Activity (WCSS)

    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.

    Measured: Baseline to post-treatment

  4. Parent Modeling 4: Weight and Body Concerns (FERF-Q)

    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.

    Measured: Baseline to post-treatment

  5. Communication 1: Negative Maternal Weight-related Commentary (FERF-Q)

    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.

    Measured: Baseline to post-treatment

  6. Communication 2: Observed Parent-adolescent Communication Quality (DOCS)

    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.

    Measured: Baseline to post-treatment

Questions about this trial

What is this clinical trial studying?

A study of Adolescent Obesity, run by The Miriam Hospital at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 30 Sep 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Body Mass Index (time frame: Baseline and at completion of 16 week intervention). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Sep 2016.
