Self-Weighing Instruction Feasibility Study
30. oktober 2019 opdateret af: 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?

Detaljeret beskrivelse
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.

Changes in Depression Ratings
Tidsramme: 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.

Changes in Anxiety
Tidsramme: 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.

Changes in Body Image
Tidsramme: 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.

Changes in Barriers to Weight Tracking
Tidsramme: 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.

Changes in Perceptions of Weight Tracking
Tidsramme: 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.
