Web Based Follow up Intervention in Obesity Treatment for Women

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?

Treatment and study plan

Follow Up Support

Behavioral

inputs will be based on elements derived from cognitive behavioural therapy, acceptance and commitment therapy, mindfulness and awareness training

Primary outcomes

  1. Changes in nutrition- and exercise self-efficacy

    Time frame: 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 outcomes

  1. Dropout rate

    Time frame: 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 outcomes

  1. Sustainability of weight loss

    Time frame: 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)
