- Masking: Single
Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Behavioral Weight Loss
|
All participants will receive twelve weeks of BWL treatment.

Measure Description |
Time Frame |
---|---|---|
Body Mass Index
Time Frame: Post-treatment (3 months)
|
BMI is calculated using measured height and weight- kg/m2.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Eating Disorder Psychopathology
Time Frame: Post-treatment (3 months)
|
Eating-disorder psychopathology is a continuous variable as assessed by the global score of the Eating Disorder Examination/Eating Disorder Examination-Questionnaire. Scores range from 0-6 (0=no eating-disorder psychopathology; 6=severe eating-disorder psychopathology).
|
Post-treatment (3 months)
|
Depressive Symptoms
Time Frame: Post-treatment (3 months)
|
Depressive symptoms will be assessed by the Patient Health Questionnaire-9.
The range is 0-27, which higher scores indicative of greater depressive symptomatology
|
Post-treatment (3 months)
|
Food Craving
Time Frame: Post-treatment (3 months)
|
Food craving will be assessed by the Food Craving Inventory (FCI).
FCI scores range from 1-5, with higher scores indicative of greater craving.
