Web Based Follow up Intervention in Obesity Treatment for Women

March 6, 2015 updated by: FEM Süd

Effects on Self-efficacy, Sustainability and Drop Out Rate Using 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?

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Internet

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.

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

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.

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

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
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
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.
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)

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
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)
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)
