Trial Outcomes & Findings for Uniting Couples in the Treatment of Binge-Eating Disorder (NCT NCT03784820)

NCT ID: NCT03784820

Last Updated: 2023-04-11

Results Overview

Binge-eating abstinence is measured using the Eating Disorder Examination-Questionnaire (EDE-Q) and is the number of participants across study time points achieving abstinence from objective binge eating over the past 28 days. The EDE-Q measure replaces the measure in the protocol to capture a month of abstinence. The weekly binge measure was unsuitable upon review of the data because the 4 times weekly measures did not capture an exact 4-week time frame because of therapy scheduling irregularities, as verified by date-stamps of measure completion. Also, the weekly binge measure captured the past 7 days and was administered every session and once at other timepoints.

Participant Flow

Participants were recruited between September 2018 to January 2021 from local physician offices, social media, advertisements, and local listservs. Potential participants were asked to contact the Research Coordinator for more information. Potential participants completed a screening questionnaire by phone with the Research Coordinator. The setting for the study was an outpatient clinic at the University of North Carolina at Chapel Hill.

After consenting to participate and completing an initial phone screening, participants were asked to complete a pre-treatment assessment consisting of electronic questionnaires and an in-person interview to determine study eligibility. The patient with binge-eating disorder (BED) in each couple had to provide written certification from their primary care provider (PCP) that their health status was suitable for this study. After determining eligibility, patients were randomized.

Eating disorder symptomatology is measured using the Eating Disorder Examination-Questionnaire (EDE-Q) global score. This self-report questionnaire assesses the presence and degree of specific psychopathology associated with eating disorders over the previous 28 days. The global score is obtained by summing the four subscale scores (Restraint, Eating Concern, Shape Concern, and Weight Concern) and then dividing this sum by the number of subscales (i.e., four). The global score range is 0 - 6. Higher scores are indicative of greater eating disorder symptomatology (i.e., worse outcome).

The Yale-Brown Obsessive-Compulsive Scale Modified for Binge-Eating measures the obsession of binge-eating thoughts and compulsiveness of binge-eating behaviors. The scale is a clinician-rated, 10-item scale, each item rated from 0 (no symptoms) to 4 (extreme symptoms). The total score range is 0 to 40. Higher scores indicate greater severity of compulsive behaviors and preoccupations related to binge-eating.

Population: Both patients and partners completed this measure. Participants who provided data were analyzed. Some participants provided partial data at study time points, further, one participant was no longer in a relationship for midpoint-6 month follow-up (T1-T4) assessments and thus, did not complete couple-based measures; this explains discrepancy(ies) between the mITT Participant Flow N and N analyzed.

The partner version of the Difficulties in Emotion Regulation Scale is an 8-item modified version of the DERS. It is a self-report scale that assesses perceptions of one's partner's emotion regulation ability and skills. Three items from the Impulse Control Difficulties (ICD) and 5 items from the Emotion Regulation Strategies (ERS) subscale were administered. Item responses range from 1 to 5 and the total score is the sum of the items. The total score range is 8 to 40. Higher scores indicate more (perceived) difficulties in one's partner's emotion regulation.

The Communication Patterns Questionnaire-Short Form (modified for Binge-Eating Disorder) assesses how the couple communicates about binge-eating when the issue arises and when discussing the issue. Item responses range from 1 to 9. The three subscales measured are Self Demand/Partner Withdraw (3 items), Partner Demand/Self Withdraw (3 items), and Constructive Communication (3 items). The Demand/Withdraw subscales were combined and have a score range of 6 to 54 and the Constructive Communication subscale has a score range of 3 to 27. Higher (subscale) sum scores indicate more of those types of behaviors, respectively; high scores on the Demand/Withdraw and low scores on the Constructive Communication subscale are worse, respectively.

SECONDARY outcome

Timeframe: Pre (T0), Mid-Treatment (after 8 weekly treatment sessions) (T1), Post (after 16 weekly treatment sessions) (T2), 3 Month Fup (T3), 6 Month Fup (T4)

Population: Both patients and partners completed this measure. Participants who provided data were analyzed. Some participants provided partial data at study time points, further, one participant was no longer in a relationship for midpoint-6 month follow-up (T1-T4) assessments and thus, did not complete couple-based measures; this explains discrepancy(ies) between the mITT Participant Flow N and N analyzed.

This revised version of the Marital Satisfaction Inventory is a 150-item true/false self-report assessment of marital distress. For the purposes of this study the investigators examined the 13-item Affective Communication scale (ACS), which assesses general communication. ACS scores range from 0-13 with higher scores indicating poorer affective communication skills.

SECONDARY outcome

Timeframe: Post (after 16 weekly treatment sessions) (T2)

Population: Patients in CBT-E and UNITE, and partners in UNITE, completed this measure. CBT-E partners did not complete this measure as they did not receive any treatment. Participants who provided data were analyzed. Some participants provided partial data at study time points, explaining discrepancy(ies) between the mITT Participant Flow N and N analyzed.

Treatment acceptability was measured with the 8-item Client Satisfaction Questionnaire, a validated acceptability measure. Item responses run on a scale of 1 to 4, with a total score range of 8-32. Higher scores indicate greater treatment satisfaction (acceptability). An independent samples t test was conducted.

OTHER_PRE_SPECIFIED outcome

Timeframe: From Pre-treatment through Follow-up

Couple communication will be assessed by rating of a 10-minute videotaped conversation in which the couple is asked to share thoughts, feelings, and concerns about some aspect of the patient's binge-eating disorder. Scoring will be based on the Couples Interaction Rating System (CIRS) and Social Support Interaction Rating System (SSIRS), observational coding systems that assess communication behaviors, affective expression, and supportive behavior.

OTHER_PRE_SPECIFIED outcome

Timeframe: From Pre-treatment through Follow-up

Couple interpersonal problem-solving/behavior change skills will be assessed by rating of a 10-minute videotaped conversation in which the couple is asked to problem-solve on some aspect of the patient's binge-eating disorder and attempt to agree upon behavioral changes that they will make. Scoring will be based on the Couples Interaction Rating System (CIRS) and Social Support Interaction Rating System (SSIRS).

OTHER_PRE_SPECIFIED outcome

Timeframe: From Pre-treatment through Follow-up

Two 10-minute video-taped interactions during which the couple is asked to share thoughts, feelings, and concerns about some aspect of the patient's binge-eating disorder and to problem-solve on some aspect of the patient's binge-eating disorder, respectively. Vocally encoded emotional arousal will be measured using fundamental frequency (f0) from patients' and partners' speech. F0 is a spectral analysis-based measure of speech prosody that refers to the lowest frequency harmonic of the speech sound wave, created by the opening and closing of the vocal folds while air flows outward from the lungs during speech production. Emotion regulation is indicated by one's ability to return to a stable set-point after being perturbed from that set-point. Stronger regulation is indicated by a faster return to the set-point. The range of fundamental frequency for speech in adult men and women is approximately 75-300hz.
