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.
