Outcome measures
Primary outcome
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 outcome
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.
Study objective
1) Personalized lifestyle advices are an effective way to reduce loss of pleasure in young individuals
2) Exposure to a tandem skydive experience fosters the recommended lifestyle changes that can restore the ability to experience pleasure
Study design
Diary questionnaires three times a day for three months; more extensive questionnaires and blood samples at the start of the study and after 1, 2, 3, 9, and 15 months.
Intervention
The participants are randomly assigned to three groups. The first month is used for observation (diary data) in all three anhedonic groups. At the start of the second month (the first intervention month), one group receives personalized lifestyle advice based on patterns observed in the first month. The second group receives personalized lifestyle advice plus a tandem skydive. The third group receives neither lifestyle advice nor a tandem skydive. At the start of the third month, all participants are free to choose between no intervention, (continued) lifestyle advice, and/or (another) tandem skydive.
