Outcome Measures

Primary Outcomes (2)

  • Change Eating behaviours

    Eating behaviors: We will assess emotional eating, uncontrolled eating and Primary outcomes will be scored on the subscales "emotional eating" and "uncontrolled eating" on the TFEQ-R21. The predetermined criterion for clinically important improvement at 12 weeks will be a decrease of 15% from baseline on the emotional eating and uncontrolled eating subscale (range 0 to 100)

    This co-primary outcome will be assessed, first, one week before the start of the 10 weeks intervention, and second, 1 week after the termination of the 10-weeks intervention. In addition a 1 and 4 year follow-up have been performed

  • Change Affective symptoms

    Affective symptoms will be assessed With the HADS

    This co-primary outcome will be assessed, first, one week before the start of the 10 weeks intervention, and second, 1 week after the termination of the 10-weeks intervention. In addition a 1 and 4 year follow-up have been performed

Secondary Outcomes (1)

  • Body weight - digital scale

    As for primary outcome

Other Outcomes (1)

  • Health related quality of life - impact of weight on quality of life (IWQOL-lite)

    1 and 4 years after surgery
