Self-Weighing Instruction Feasibility Study

October 30, 2019 updated by: University of Minnesota
Scant data have been reported on the effects of weight self-monitoring during weight control. The purpose of this pilot project was to consider the questions: Is it possible to assign participants to engage in daily weight self-monitoring, and are there differential effects on mood of daily versus weekly weighing?

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study tested the feasibility of assigning participants to daily or weekly weighing, monitored adherence to weighing instructions, and tracked additional behavioral and psychosocial indicators over a period of six months. It was hypothesized that there would be no differences in mood or adherence between daily versus weekly weighing conditions. Knowledge about the benefits of frequent self-weighing may shape public health recommendations for regular weighing as a weight reduction or obesity prevention strategy.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Adherence to Weight Tracking Instructions
Time Frame: 6 months
Participants were assigned to daily or weekly weight tracking, and were asked to return postcards once a week with weights recorded (7 for daily, 1 for weekly).
6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Changes in Depression Ratings
Time Frame: baseline to 6 months
Ratings of depressed mood, assessed by the Beck Depression Inventory, were obtained at baseline, three, and six months; the comparison of depression scores between groups and over time from baseline to 3 and 6 months was considered as a secondary outcome and analyzed using repeated measures multivariate analysis of variance (MANOVA). Scores on the inventory range from 0 to 63, with higher scores indicating greater presence of depressive symptoms. Scores from 0-10 represent normal mood; 11-16 = mild mood disturbance; 17-20 = borderline clinical depression; 21-30 = moderate depression; 31-40 = severe depression; > 40 = extreme depression.
baseline to 6 months
Changes in Anxiety
Time Frame: baseline to 6 months
Ratings of anxiety, assessed by the Beck Anxiety Inventory, were assessed at baseline, three, and six months; a comparison of anxiety scores between groups and over time from baseline to 3 and 6 months was considered a secondary outcome and analyzed using repeated measures MANOVA. Possible scores on the scale range from 0-63. Scores from 0-7 indicate minimal anxiety; 8-15 = mild anxiety; 16-25 = moderate anxiety; 26-63 = severe anxiety.
baseline to 6 months
Changes in Body Image
Time Frame: baseline to 6 months
Changes in self-reported body image were assessed at baseline, three, and six months using the Appearance subscale of the Multidimensional Body Image Questionnaire. The subscale has a range of 0 to 42, with higher scores indicating better body image. A comparison of body image scores between groups and over time from baseline to 3 and 6 months was considered a secondary outcome and analyzed using repeated measures MANOVA.
baseline to 6 months
Changes in Barriers to Weight Tracking
Time Frame: baseline to 6 months
Perceived barriers to self-weighing were assessed at baseline, three, and six months using a scale created for this study. The scale has a range of 18 to 90, with higher scores indicating greater perceptions of barriers to self-weighing. A comparison of barriers scores between groups and over time from baseline to 3 and 6 months was considered a secondary outcome and analyzed using repeated measures MANOVA.
baseline to 6 months
Changes in Perceptions of Weight Tracking
Time Frame: three to six months
Perceptions of weight tracking (ease of remembering and understanding, usefulness, awareness, interest, reward value, satisfaction, motivational value) were assessed at three and six months using a scale created for the study. The scale has a range of 0 to 64, with higher scores indicating greater perceptions of favorability of weight tracking. A comparison of perceptions scores between groups and over time from 3 and 6 months was considered a secondary outcome and analyzed using repeated measures MANOVA.
