About this study
The purpose of this study is to examine the feasibility, acceptability, and preliminary efficacy for the inclusion of support figures and romantic partners throughout the bariatric surgery process, from pre-surgery to two months post-surgery. This will be done using a four-arm randomized controlled trial (RCT). Using simple randomization, female patients in romantic relationships will be randomized into partner attended (PA) groups and treatment as usual (PA-TU) groups; patients (female or male) not in romantic relationships will be randomized into support figure attended (SFA) and SFA-TU groups.
The goals of this study are to provide preliminary evidence for including support figures/partners in patients' routine BS healthcare visits, including the subsequent impact on post-surgery patient and support figure/partner behavior change and weight loss, relationship outcomes, and exploration of barriers to support figure/partner involvement.

Aim 1: To assess the feasibility and acceptability of support figure/partner involvement for BS patients. Feasibility will be assessed throughout the study by attendance at the four pre-surgery classes and the clinic visit assessment time points. Perceived fiscal and time involved in the study will be assessed. Acceptability will be assessed from patient and support figure/partner interviews regarding the barriers and benefits to attendance, and alternative mediums to engage support figures/partners.
Aim 2: To evaluate the effect of support figure/partner attendance (SFA, PA arms) on patient weight loss, behavior change, and relationship outcomes from T1-T4. Estimates of effect size and variance in patient weight loss and behavior change will be collected from T1-T4 for comparison of the SFA/PA and SFA-TU/PA-TU arms.

The purpose of this study is to examine the feasibility, acceptability, and preliminary efficacy for the inclusion of support figures and romantic partners throughout the bariatric surgery process, from pre-surgery to two months post-surgery. This will be done using a four-arm randomized controlled trial (RCT). Using simple randomization, female patients in romantic relationships will be randomized into partner attended (PA) groups and treatment as usual (PA-TU) groups; patients (female or male) not in romantic relationships will be randomized into support figure attended (SFA) and SFA-TU groups.
The goals of this study are to provide preliminary evidence for including support figures/partners in patients' routine BS healthcare visits, including the subsequent impact on post-surgery patient and support figure/partner behavior change and weight loss, relationship outcomes, and exploration of barriers to support figure/partner involvement.
Inclusion criteria for the PA arm requires patients be pre-surgery and registered for pre-surgery classes, identify as female, and in a romantic relationship with a cohabitating partner/spouse for at least 6 months. Inclusion criteria for the SFA arm requires patients be pre-surgery and registered for pre-surgery classes, and not be in a cohabitating romantic relationships. Known terminal illness diagnosis excludes patients and support figure/partner participation. The recruitment goal is 110 dyads in all four arms of the study (SFA, SFA-TU, PA, PA-TU).
Patients in all arms will receive routine care, which includes four pre-surgery classes and routine clinical visits. Support figures/partners of patients in the SFA and PA arms will be requested to attend the four pre-surgery classes with the patient and the three clinical visits; patients in the SFA-TU and PA-TU arms will attend individually. Assessments will be completed by patients and support figures/partners (all four arms) at the first pre-surgery class (T1) and routine clinical visits: the pre-surgery appointment (T2), two-weeks post-surgery appointment (T3), and at the two-months post-surgery appointment (T4).
Aim 1: To assess the feasibility and acceptability of support figure/partner involvement for BS patients. Feasibility will be assessed throughout the study by attendance at the four pre-surgery classes and the clinic visit assessment time points. Perceived fiscal and time involved in the study will be assessed. Acceptability will be assessed from patient and support figure/partner interviews regarding the barriers and benefits to attendance, and alternative mediums to engage support figures/partners.
Aim 2: To evaluate the effect of support figure/partner attendance (SFA, PA arms) on patient weight loss, behavior change, and relationship outcomes from T1-T4. Estimates of effect size and variance in patient weight loss and behavior change will be collected from T1-T4 for comparison of the SFA/PA and SFA-TU/PA-TU arms.
Hypothesis. Patients in the SFA and PA arms will experience increased weight loss, physical activity frequency, and higher compliance with post-surgery dietary recommendations compared to patients in the SFA-TU and PA-TU arms at T4.
Sub-aim 2.1. To evaluate the effect of attendance on support figure/partner weight status. Support figures and partners will complete measures of weight status at the same time points as the patient. Because it is largely unknown if support figures/partners could benefit from intervention with the patient, or if support figures/partners' weight status is similar to the patients, we will explore support figures/partners' weight status and if their weight status changes from T1 to T4.
Sub-aim 2.2. To determine the preliminary effect of attendance on relationship outcomes. Patients and support figures/partners will complete self-report measures of relationship quality (PA-only), attachment security (PA-only), family functioning, and perceived social support from T1-T4 to determine the effect of attendance on patient and support figure/partners' perspectives of relationship outcomes.

What is being measured
The primary outcome is the main question the study is designed to answer.
Percent Excess Weight Loss (%EWL, Patient)
[(T1 weight in lbs) - (Follow up (T2-T4) Weight)] / [(TI Weight) - (Ideal Weight)]
Measured: 6 months, 4 time points
Secondary outcomes (4)
Dietary Compliance (Patient)
Trained dieticians will conduct oral 24-hour recalls with patients and rate as (0) not compliant or (1) compliant. Ratings are based on the American Society of Metabolic Bariatric Surgery (ASMBS) surgery guidelines.
Measured: 6 months, 4 time points
Physical Activity (Patient)
Scale Name: Bouchard's Physical Activity Record. Items 1-9 are totaled to assess physical activity intensity, ranging from 24-96, where higher scores indicate higher intensity of activity throughout the day.
Measured: 6 months, 4 time points
Relationship Quality (Patient and Partner)
Scale Name: Abbreviated Dyadic Assessment Scale (ADAS). There are 7 items to assess relationship quality on a continuous scale from 0-35, where higher scores indicate higher relationship quality. Items are scored on a 0-5 scale for items 1-6, and 0-6 scale for item 7.
Measured: 6 months, 4 time points
Perceived Social Support for Behavior Change (Patient and Partner/Support Figure)
Scale Name: Social Support for Eating Habits and Exercise. There are 23 items scored on a continuous scale ranging from 23-115 to assess perceived social support for behavior change, where higher scores indicate higher perceived support. Each item is scored on a scale ranging from 1-5. There are four subscales 1) encouragement of eating habits (items: 1-5); 2) discouragement of eating habits (6-10); and 3) family participation in exercise (items 11-16, 20-23); and 4) punishment for exercise (items: 17-19).
Measured: 6 months, 4 time points

Perceived fiscal and time involved in the study will be assessed. Acceptability will be assessed from patient and support figure/partner interviews regarding the barriers and benefits to attendance, and alternative mediums to engage support figures/partners.
Aim 2: To evaluate the effect of support figure/partner attendance (SFA, PA arms) on patient weight loss, behavior change, and relationship outcomes from T1-T4. Estimates of effect size and variance in patient weight loss and behavior change will be collected from T1-T4 for comparison of the SFA/PA and SFA-TU/PA-TU arms.

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percent Excess Weight Loss (%EWL, Patient) (time frame: 6 months, 4 time points). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03642197, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Sep 2025.
