Web Based Follow up Intervention in Obesity Treatment for Women

Study Overview
=================
Brief Summary
-----------------
This study is designed to verify that web based follow up intervention after a classic multidisciplinary face-to-face obesity treatment will reinforced nutrition and exercise self-efficacy, improve drop out rate and advance sustainability after weight loss of obese women. Research Questions and Hypotheses How does a web based follow up intervention change self-efficacy of women participating in an obesity intervention? How does a web based follow up intervention affect the drop out rate of women participating in an obesity intervention? How does a web based follow up intervention influence sustainability of women participating in an obesity intervention?

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Internet<br>Participants of this intervention group get follow up support via Internet. They have access to new inputs biweekly consisting of Thematic inputs and instructions (e.g. advice on shopping, cooking, regular exercise on daily routine, motivation and more) assignments promoting self-awareness and introspection spreadsheets promoting self-monitoring News and updates (e.g. recipes, gymnastic classes, meetings of self support groups and more) will be available each month. Tailored feedback of their behaviour will be given by documentation on spreadsheets. | Behavioral: Follow Up Support<br>* inputs will be based on elements derived from cognitive behavioural therapy, acceptance and commitment therapy, mindfulness and awareness training<br>|
| Experimental: Printed Manual<br>Participants of this intervention group get follow up support via a printed manual. The manual consist of all the same inputs as are available to the Internet follow up group. Thematic inputs and instructions (e.g. advice on shopping, cooking, regular exercise on daily routine, motivation and more) assignments promoting self-awareness and introspection spreadsheets promoting self-monitoring All inputs will be given at once at the beginning of the follow up intervention, only news and updates (e.g. recipes, gymnastic classes, meetings of self support groups and more) will be sent per mail each month. There is no tailored feedback of their behaviour as the paper-pencil documentation on spreadsheets can't be monitored by the psychologists. | Behavioral: Follow Up Support<br>* inputs will be based on elements derived from cognitive behavioural therapy, acceptance and commitment therapy, mindfulness and awareness training<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes in nutrition- and exercise self-efficacy | Changes in nutrition- and exercise self-efficacy will be measured by scores in questionnaires for nutrition- and exercise self-efficacy (Sportbezogene Selbstwirksamkeitserwartung - Fuchs & Schwarzer, 1994 and Weight Efficacy Life-Style Questionnaire - Clark et al. 1991). A change of more than one standard deviation will be considered significant. | Primary outcome measure is assessed at the beginning of the follow up support (baseline) and after 6 months (at completion of the follow up intervention by Internet or printed manual) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Dropout rate | The Dropout rate will be compared by the number of women available for the last meeting at the end of the follw up intervention. | Secondary outcome measure is assessed at the beginning of the follow up support (baseline) and after 6 months (at completion of the follow up intervention by Internet or printed manual) |
