Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main study endpoint of the intervention study is the level of pleasure, as measured in the daily questionnaires. Change in pleasure will be evaluated both intraindividually (time series approach) and interindividually (multilevel approach). | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary endpoints concern possible intervention effects in monthly-reported pleasure in different dimensions (motivational, anticipatory, consummatory) and different domains (perceptual, physical, social). Other endpoints that will be explored are changes in potential biomarkers, perceived physical and mental health, and positive and negative affect. Furthermore, the extent to which the lifestyle advice will lead to actual lifestyle change will be investigated by comparing the level and slope of the lifestyle variables in the pre- and post-intervention period. | — |
