Brief summary
The aim of this study is to evaluate an eHealth intervention facilitating weight maintenance following initial weight loss during a 3-month trial (pilot test)
Detailed description
Obesity rates are rapidly increasing and even with diets and interventions aiding weight loss, an alarmingly large percentage of people struggle to maintain the lost weight. In the face of obesity, weight maintenance is therefore arising as a major obstacle and new innovative approaches are called for. Despite the fact that a substantial number of web-based diets, health and fitness focused interventions or apps already exist, few focus on weight maintenance, are research based or available post study. In addition, most have yet to show short- or long-term effect and few, if any, are developed together with users (e.g., patients, health care professionals). eHealth solutions may therefore be a missing link in supporting self-regulation and motivation for sustainable health behavior change and weight loss maintenance. The aim of this study is to evaluate a person-centered, evidence based interactive eHealth intervention facilitating weight maintenance following initial weight loss during a 3- month feasibility pilot trial.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Efficacy and usability | Baseline and at 3 months post baseline | Collected data from system use log and from study specific system usefulness questions (use and perceived usefulness) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Weight | Baseline and at 3 months post baseline | Weight measurement |
Other
| Measure | Time frame | Description |
|---|---|---|
| System Usability Scale (SUS) | At 3 months post baseline | 1o item scale measuring usability, with five response options for respondents; from Strongly agree to Strongly disagree. The obtainable score range is 25 to 100. A SUS score above a 68 would be considered above average and anything below 68 is below average. |
| TWente Engagement with Ehealth Technologies Scale (TWEETS) | At 3 months post baseline | To measure behavioral, cognitive and affective engagment with a 5 point Likert scale: strongly disagree, disagree, neutral, agree, strongly agree |
| The Hospital Anxiety and Depression Scale (HADS) - Assessing change | At baseline and at 3 months post baseline | 14 item scale measuring anxiety and depression. Respondents are asked to indicate which of 4 response options (rated from 0-3; score range, 0-42) comes closest to describing how they have been feeling in the previous week for each item. Scores from 0-7 on the subscales are regarded as being in the normal range; a score of 11 or higher indicates a probable presence of a mood disorder, and a score of 8-10 is suggestive of the presence of the state. |
| Three-Factor Eating Questionnaire (TFEQ-R21) | Baseline and at 3 months post baseline | 21 item scale to evaluate cognitive restraint, emotional eating and bingeing behaviors |
| Weight-related Symptom Measure (WRSM) | At baseline and at 3 months post baseline | Patient reported outcome measures that assesses the symptoms that are commonly associated with obesity, next to quality of life, general functional status and well-being. |
| Treatment Self-Regulation Questionnaire (TSRQ diet and exercise) | At baseline and at 3 months post baseline | A theoretically derived scale which assesses the degree of autonomous self-regulation regarding why people engage or would engage in healthy behavior |
| Perceived Competence Scale (PCS) (diet and exercise) | At baseline and at 3 months post baseline | A 4-item questionnaire, that assesses participants' feelings of competence about engaging in a healthier behavior (e.g., diet) and participating in a physical activity regularly. |
| RAND Health Related Quality of Life | 36 item scale measuring health related quality of life. The RAND-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question | At baseline and at 3 months post baseline |
| Pittsburgh Sleep Quality Index (PSQI) | Baseline and at 3 months post baseline | A self-reporting questionnaire of 19 individual items, creating 7 components that produce one global score. |
