简要总结
The purpose of the present study was to conduct a pilot RCT to test the feasibility of a physician-delivered ACT-based intervention for emotional eaters with overweight/obesity against standard care at a network of weight loss clinics. Participants were randomized to receive either standard care at the clinics or the ACT intervention.
详细描述
The purpose of the present study was to conduct a pilot RCT to test the feasibility of a physician-delivered ACT-based intervention for emotional eaters with overweight/obesity against standard care at a network of weight loss clinics. Psychology clinical PhD students trained physicians in the delivery of the brief manualized intervention and were available for regular consults. The intervention consisted of eight, 5-10 minute sessions that could be easily incorporated into the physician's current practice. Over the duration of the ACT intervention, physicians met individually with patients to teach them various techniques to address and improve mindfulness, acceptance, and values clarification and commitment, all of which emotional eaters have been found to struggle with (Forman & Butryn, 2014). The proven habit formation technique of if-then planning (Gollwitzer, 1993) was used throughout these sessions in order to train emotional eaters to habitually use ACT techniques and to change the maladaptive habit of eating in response to negative emotions.

盲法说明
Participants were blind to their condition, but physicians and administrative staff were not blind to participant condition. Physicians were not blind to participant condition because they were responsible for delivering the ACT intervention or standard care. They were thus required to know the participant's condition in order to deliver the adequate treatment. Administrative staff was responsible for providing physicians with this information and organizing study paperwork and thus needed to be aware of participant condition as well.

结局指标
主要结局
Emotional Eating Change
时间窗: Baseline to Post-Intervention (on average, 16 weeks)
Assessed by the Dutch Eating Behavior Questionnaire (DEBQ) emotional eating subscale. Scores range from 1 (never) to 5 (very often). Lower scores reflect lower emotional eating. This subscale score is calculated by taking the mean of all items on the subscale. Negative change scores reflect decreases in emotional eating.
Weight Change
时间窗: Baseline to Post-Intervention (on average, 16 weeks)
Weight change in kilograms
