Brief Summary

Bulimia Nervosa (BN), Binge Eating Disorder (BED) and Night Eating Syndrome (NES) are Binge Eating Disorders (BE-Dis) in which binge eating episodes are a main symptom. Cognitive Behavioral Therapy (CBT) is the leading evidence-based treatment for patients suffering from these disorders. CBT-E is an "enhanced" trans-diagnostic version of the treatment which appears to be more effective in a variety of Eating Disorders (EDs). The main goals of this treatment are reducing dietary restrictions and EDs symptoms as well as food intake regulation. Self-monitoring (SM) is an important and central tool in this type of treatment considered crucial for its success. Therefore, during treatment, patients are required to monitor their eating, the circumstances, and their thoughts and feelings proximate to the time of eating. Nevertheless, despite the importance of this tool, research has shown that there are many difficulties challenging the clients' adherence to SM, which might reduce this treatment's effectiveness and outcome. Additionally, in recent years there has been cumulative data supporting the use of mindfulness in the treatment of EDs. Mindfulness, as a western psychological approach, is defined as the "unique non-judgmental focus of one's attention at the present moment". Although SM requires the ability to observe, describe and identify occurrences, no studies have yet examined the direct effect of mindfulness skills on SM adherence, and therefore the improvement of treatment outcomes. The main objective of the present study is to examine the effect of a mindfulness based intervention on SM adherence during a CBT intervention for BE-Dis, and on the treatment outcomes as seen in the ED psychopathology and compliance to the nutritional instructions and food intake composition. Other aims include examining the differences between the experimental group and the control group, regarding their level of mindfulness and SM adherence. In addition, mediating and moderating processes between mindfulness and SM adherence will be examined.

Outcome Measures

Primary Outcomes (5)

  • Changes in the Eating Disorder Examination Questionnaire (EDE-Q-I)

    EDE-Q-I (Eating Disorder Examination Questionnaire; Fairburn \& Beglin, 1994): A self-report measure of eating disorders psychopathology.

    8 Time points: Recruitment (entry to study), pre-CBT-E (5 weeks from recruitment), along CBT-E (10, 5, 20 weeks from recruitment), post-CBT-E (24 weeks from recruitment), follow-up (3 and 6 months post CBT-E = 9 and 12 months post recruitment)

  • Changes in the Clinical Impairment Assesment (CIA) questionnaire

    Assessment of psychosocial impairment due to eating disorder will be conducted through CIA (Clinical Impairment Assesment) self-report questionnaire (Bohn \& Fairburn, 2008).

    8 Time points: Recruitment (entry to study), pre-CBT-E (5 weeks from recruitment), along CBT-E (10, 5, 20 weeks from recruitment), post-CBT-E (24 weeks from recruitment), follow-up (3 and 6 months post CBT-E = 9 and 12 months post recruitment)

  • Changes in the Night Eating Questionnaire (NEQ)

    Assessment of Night Eating Syndrome psychopathology will be conducted through NEQ (Night Eating Questionnaire) self-report questionnaire (Allison et al., 2008).

    8 Time points: Recruitment (entry to study), pre-CBT-E (5 weeks from recruitment), along CBT-E (10, 5, 20 weeks from recruitment), post-CBT-E (24 weeks from recruitment), follow-up (3 and 6 months post CBT-E = 9 and 12 months post recruitment)

  • Changes in the treatment Outcome Questionnaire-45 (OQ-45)

    OQ-45 (Outcome Questionnaire-45) (Lambert et al., 1996) is a self-report scale used to estimate client degree of disturbance at the outset and over the course of treatment. It measures three subscales: symptom distress (depression and anxiety), interpersonal relationships and social role (difficulties in the workplace, school or home duties).

    8 Time points: Recruitment (entry to study), pre-CBT-E (5 weeks from recruitment), along CBT-E (10, 5, 20 weeks from recruitment), post-CBT-E (24 weeks from recruitment), follow-up (3 and 6 months post CBT-E = 9 and 12 months post recruitment)

  • Treatment outcomes as seen in the compliance to the nutritional instructions (conducted through analyzing the self monitoring documents )

    Treatment outcomes regarding the compliance to the nutritional instructions, will be examined by analyzing the participants' self monitoring reports. This analysis will be conducted by comparing the actual number of meals a day and the composition of food consumed (and reported) to dietary recommendations for the treatment of binge eating disorders (Fairburn \& Wilson, 1993). Nutritional composition analysis of food consumed will be conducted by using the "Tzameret" software (of the Israeli Ministry of Health). This procedure will be conducted before (week 1), during (week 10) and at the end of the CBT program (week 19).

    Analyzed at 3 time points along the CBT-E program: week 1, week 10, week 19 (end of CBTprogram)

Secondary Outcomes (1)

  • Self monitoring adherence (conducted through scoring the self monitoring content of the participants)

    Every week along 19 weeks of CBTE program

Other Outcomes (8)

  • Mediating and moderating processes between mindfulness and SM adherence: Depression and anxiety (will be examined through self-report questionnaires)

    8 Time points: Recruitment (entry to study), pre-CBT-E (5 weeks from recruitment), along CBT-E (10, 5, 20 weeks from recruitment), post-CBT-E (24 weeks from recruitment), follow-up (3 and 6 months post CBT-E = 9 and 12 months post recruitment)

  • Mediating and moderating processes between mindfulness and SM adherence: Motivation (will be examined through self-report questionnaires)

    8 Time points: Recruitment (entry to study), pre-CBT-E (5 weeks from recruitment), along CBT-E (10, 5, 20 weeks from recruitment), post-CBT-E (24 weeks from recruitment), follow-up (3 and 6 months post CBT-E = 9 and 12 months post recruitment)

  • Mediating and moderating processes between mindfulness and SM adherence: Attention deficit disorder (will be examined through self-report questionnaires)

    8 Time points: Recruitment (entry to study), pre-CBT-E (5 weeks from recruitment), along CBT-E (10, 5, 20 weeks from recruitment), post-CBT-E (24 weeks from recruitment), follow-up (3 and 6 months post CBT-E = 9 and 12 months post recruitment)

Behavioral: MINDBehavioral: CBT-E

Interventions

MINDBEHAVIORAL

Both experimental and control groups receive 20 weekly sessions (1.5 hours each), based on principles of CBT-E (Fairburn, 2008), adapted for a group format . The experimental group will receive in addition to CBT-E a mindfulness based intervention comprising of 4 weekly group sessions (1.5 hours each) during the month prior to the CBT-E program. The mindfulness skills intervention will also be practiced throughout the CBT-E program at the beginning of every group session and independently as homework. Mindfulness intervention includes "formal" mindfulness practice (brief mindfulness meditation - 10 minutes each) and "informal" mindfulness practice (Other "non meditation exercises", also known as "mindfulness in everyday life"- eg "STOP").

Experimental group (CBTE-MIND)
CBT-EBEHAVIORAL

The comparison group (control) will receive 4 weekly supportive-educational group sessions (1.5 hours each) prior to the group CBT-E program, with no mindfulness content or training.
