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?

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes in nutrition- and exercise self-efficacy | 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) | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Dropout rate | 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) | The Dropout rate will be compared by the number of women available for the last meeting at the end of the follw up intervention. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Sustainability of weight loss | Further 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) | Sustainability will be measured in * percentage of women successfully stabilized weight (range of ± 2 kg based on Cooper et al. (2008) * percentage of women keeping the scores or impair no more than 1 standard deviation in their test results (Ad Eva Testsystem zur Diagnostik und Evaluation bei Adipositas - Ardelt-Gattinger und Meindl, 2009; Sportbezogene Selbstwirksamkeitserwartung - Fuchs & Schwarzer, 1994; Weight Efficacy Life-Style Questionnaire (WEL) - Clark et al., 1991; SF 36 - Fragebogen zum Gesundheitszustand - Bullinger und Kirchberger, 1998) |
