Change in Adolescent Body Mass Index (BMI) |
Objectively measured BMI/BMI z-score/BMI percentile for age and sex; |

|
Primary |
Change in Adolescent Emotional Eating |
Emotional Eating Scale for Children (EES-C) total score, which is derived from an average of all 26 items (range = 0-4). Higher scores indicate higher levels of emotional eating. |
baseline to intervention completion (approx 14 weeks), baseline to 3-month follow-up (approx 26 weeks), and intervention completion to 3-month follow-up. |
|
Primary |
Change in Adolescent Perceived Stress |
Perceived Stress Scale (PSS) total score, which is derived from summing responses to all 10 items (range = 0-4 per item; 0-40 total). Higher scores indicate higher levels of stress. |
baseline to intervention completion (approx 14 weeks), baseline to 3-month follow-up (approx 26 weeks), and intervention completion to 3-month follow-up. |
|
Primary |
Change in Adolescent Stress |
Adolescent Stress Questionnaire (ASQ) total score, which is derived from summing responses to all 58 items (range = 1-5 per item; 58-290 total). Higher scores indicate higher levels of stress. |
baseline to intervention completion (approx 14 weeks), baseline to 3-month follow-up (approx 26 weeks), and intervention completion to 3-month follow-up. |
|
Primary |
Change in Adolescent Chronic Stress |
Chronic Stress Questionnaire for Children and Adolescents (CSQ-CA) total score, which is derived from summing responses to all 17 items (range = 1-4 per item; 17-68 total). Higher scores indicate more stress during the past 3 months. |

|
Primary |
Intervention Acceptability and Feasibility |
Acceptability and feasibility of the mindfulness-based behavioral weight control intervention will be measured by session attendance, dietary self-monitoring logs, and attrition rates. |
End of treatment (approx 14 weeks after baseline) |
|
Secondary |
Change in Adolescent Eating Pathology and Symptomology |
Youth Eating Disorder Examination-Questionnaire (YEDE-Q) global score, which is derived by averaging the 4 subscales of the YEDE-Q (Restraint, Eating Concern, Shape Concern, and Weight Concern). The range for the total score is 0 to 6, with higher scores indicating more severe eating pathology. |

|
Secondary |
Change in Adolescent Emotion Regulation |
Emotion Regulation Questionnaire for Children and Adolescents (ERQ-CA) includes two subscales representing emotion regulation strategies (Suppression and Reappraisal). Responses to all 10 items (range = 1-7 per item) are summed to calculate each subscale. Higher scores indicate higher use of each emotion regulation strategy. |

|
Secondary |

|
Secondary |
Change in Adolescent Mindful Attention Awareness |
Mindfulness Attention Awareness Scale - Adolescent (MAAS-A) total score, which is derived from summing responses to all 15 items (range = 1-6 per item; 15-90 total). Higher scores indicate higher trait mindfulness. |

|
Secondary |
Change in Adolescent Quality of Life - Adolescent Report |
Sizing Me Up total score, which is derived from responses on 22 items (range = 1-4). Raw scores are converted to a scaled score from 0-100, with higher scores indicating greater quality of life. |

|
Secondary |
Change in Adolescent Quality of Life - Parent/Caregiver Report |
Sizing Them Up total score, which is derived from responses on 28 items (range = 1-4). Raw scores are converted to a scaled score from 0-100, with higher scores indicating greater quality of life. |
