Recruiting

Clinical Trial NCT06724406 (FAM WEL B-ing) is an interventional study for Obesity and Overweight, Diabetes Mellitus, Weight Loss, Behavior Change that is recruiting. It started on 3 February 2025 with plans to enroll 256 participants. Led by University of North Carolina, Chapel Hill, it is expected to complete by 31 December 2028. The latest data from ClinicalTrials.gov was last updated on 29 August 2025.

Brief Summary

The goal of this clinical trial is to learn the best combination of family components that yields optimal weight loss among Black adults. The main question it aims to answer is:

What combination of four family components in combination with a standard behavioral weight loss program yields optimal weight loss among Black adults? Researchers will compare different combinations of family skills components (communication content, cohesion content, number of sessions, and mode of delivery) to see the best weight loss.

Participants will:

Participate in a 6-month behavioral weight loss intervention
Attend core weight loss in-person group sessions, and dyad based family sessions
Keep track of weight, dietary intake and physical activity

Detailed Description

This clinical trial aims to determine the most effective combination of family components to achieve optimal weight loss among Black adults. The main focus is to assess how different combinations of four family skills components-communication content, cohesion content, number of sessions, and mode of delivery-work together with a standard behavioral weight loss program.

Participants will engage in a 6-month behavioral weight loss intervention, which includes attending group weight loss sessions and family-based dyad sessions. They will also track their weight, dietary intake, and physical activity.

This is a 2 x4 factorial design with 16 study conditions.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Body weight	Body weight (kg) expressed as a continuous variable will be collected on a digital scale.	baseline and 6 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Mean Change in Blood Pressure	Both systolic and diastolic blood Pressure measured after 5 minutes of rest and taken in the same position throughout the study.	baseline and 6 months
Change in skin carotenoids	To assess fruit and vegetable intake, skin carotenoids will be measured using a reflection spectroscopy device ("Veggie Meter") The Veggie Meter uses reflection spectroscopy and a light-emitting diode (LED) light to measure the skin's carotenoids on a scale of 0 to 800. Higher scores indicate more carotenoids, which usually means the person has eaten more fruits and vegetables.	baseline and 6 months
Change in physical activity steps	To assess physical activity, the number of daily steps will be captured using a Fitbit wearable fitness tracker	baseline and 6 months
Change in glycosylated hemoglobin (A1c)	Changes in A1c will be measured using a, Point of Contact A1c -Siemens Diabetes 5075 A1C Analyzer	baseline and 6 months
Current Subjective Social Status	Assesses a person's perceived rank relative to others in their group. The MacArthur Scale of Subjective Social Status (MacArthur SSS Scale) is a single-item measure that assesses a person's perceived rank relative to others in their group. Respondents view a drawing of a ladder with 10 rungs, and either read or hear that the ladder represents where people stand in society. Respondents further read or hear: "At the top of the ladder are the people who are the best off, those who have the most money, most education, and best jobs. At the bottom are the people who are the worst off, those who have the least money, least education, worst jobs, or no job. To score this measure, researchers simply note the number of the rung (1-10) on which the respondent placed their "X."	baseline
Change in Quality of Life	12-Item Short Form Survey (SF-12) assessing the impact of health on an individual's everyday life. The 12-Item Short Form Survey (SF-12) is scored by calculating two main scores: a Physical Component Summary (PCS) and a Mental Component Summary (MCS), both ranging from 0 to 100, with higher scores indicating better physical and mental health respectively	baseline and 6 months
Change in Depression	Patient Health Questionnaire -8 (PHQ-8). To score the Patient Health Questionnaire-8 (PHQ-8), add up the scores from each of the eight items, with each item rated on a scale from 0 ("not at all") to 3 ("nearly every day") - resulting in a total score ranging from 0 to 24; higher scores indicate greater depression severity; generally, a score of 10 or higher is considered clinically significant for major depression, while scores between 5-9 are considered mild depression and 10-14 moderate depression.	baseline and 6 months
Change in Perceived stress	Measured using Perceived Stress Scale 4 (PSS-4). On the Perceived Stress Scale 4 (PSS-4), each question is scored on a 0-4 scale, with higher scores indicating greater perceived stress, and the total score is calculated by adding up all four items; the possible score range for the PSS-4 is therefore 0-16, with higher scores signifying higher levels of stress.	baseline and 6 months
Change for social support for exercise	The exercise participation subscale of the Social Support and Exercise Survey (10 items) measures social support specific to exercise behaviors. The subscale assesses the level of support for exercise from partners. Subscale example items include "Exercised with me" and "Criticized or made fun of me for exercising." Total scores range from 5 to 50, with higher scores indicating more social support for exercise participation behaviors.	baseline and 6 months
Change in Self-Efficacy of Eating Behaviors	Measured by survey responses to the Weight Efficacy Lifestyle Questionnaire Short Form (WEL-SF).Scale goes from 0 (not at all confident) to 10 (very confident). Higher scores mean better self efficacy.	baseline and 6 months
Change in Self-Efficacy of Physical Activity	The confidence subscale of the Patient-centered Assessment and Counseling for Exercise Adult Diet and Physical Activity Measure (6 items; ) measures confidence in participating in regular exercise or physical activity in different situations (e.g., "How confident are you that you would participate in regular exercise or physical activity: When I am tired?"). Items rated on a scale from 1 ("not at all confident") to 6 ("extremely confident"). Higher scores show higher self-efficacy.	baseline and 6 months
Changes in self-regulation	Treatment Self-Regulation Questionnaire. To score the Treatment Self-Regulation Questionnaire (TSRQ), each item is typically rated on a 7-point Likert scale, where 1 represents "Not at all true" and 7 represents "Very true," with higher scores indicating a greater degree of autonomous motivation for engaging in the targeted health behavior;	baseline and 6 months
Changes in nutrition self-efficacy	Nutrition Self-efficacy scale (5 items). To score a 5-item Nutrition Self-Efficacy scale, typically each item is rated on a Likert scale (usually 1-5, with 1 being "not at all confident" and 5 being "very confident"), and then the scores from all five items are added together to produce a total score, with higher scores indicating greater perceived self-efficacy in managing nutrition choices; the total score range would be between 5 (lowest self-efficacy) and 25 (highest self-efficacy)	baseline and 6 months
Physical Activity Readiness	PHYSICAL ACTIVITY READINESS QUESTIONNAIRE (PAR-Q) \& You. The Physical Activity Readiness Questionnaire (PAR-Q) is a seven-question screening tool that helps determine if a person is healthy enough to exercise. If you answer "yes" to one or more questions, you should consult a physician before starting an exercise program	baseline
Change in Family Emotional Involvement	The family emotional involvement (7 items) of the Family Emotional Involvement and Criticism Scale rate items on a 5-point Likert scale, as above.	baseline and 6 months
Change in Family Perceived Criticism	The perceived criticism (7 items) subscales of the Family Emotional Involvement and Criticism Scale rate items like on a 5-point Likert scale, as above.	baseline and 6 months
Change in Family Collaborative problem solving	The Family Problem-Solving Communication Index (10 items) was used to measure the specific communication style that families use to manage and solve problems and conflicts in various types of stressful situations. Consisting of 2 subscales, affirmatory communication and incendiary communication, the response options were "false," "mostly false," "mostly true," and "true."	baseline and 6 months
Change in Family Cohesion	The cohesion subscale (10 items) of the Family Adaptability and Cohesion Evaluation Scale III measures the emotional bonding family members have with one another. Items like "Family members ask each other for help" rated on a 5-point Likert scale from "almost never" to "almost always."	baseline and 6 months
Personal Network Survey	Social Network Analysis using Network Canvas software	baseline
