Uitkomstmaten
Primaire uitkomstmaten
The primary outcome measure is the difference between the trained and control groups in self-reported vitality directly after the training compared to baseline.
Achtergrond van het onderzoek
The main aim of this study is to evaluate the psychophysiological effects of a psychological training aimed at improving immune function in healthy male volunteers. The training consists of an internet-delivered guided psychological training, based on cognitive-behavioral principles. The control condition will not receive any training. A BCG-vaccination will be conducted after 10 weeks. Effects on vitality and other psychological and psychophysiological outcome measures will be examined, both in rest (after 10 and 14 weeks) and in response to stressors (1 day after vaccination).
Doel van het onderzoek
The aim of the study is to investigate the effects of a psychological training directed at optimizing immune function in healthy young men. It is expected that the training will lead to improved self-reported vitality (primary hypothesis), both in rest and in response to immunological (BCG vaccination) and psychological and physical stressors.
Onderzoeksopzet
The study consists of 5 sessions during the course of 14 weeks. First of all, participants will be screened for medical and psychological conditions. Thereafter, a training period preceded by a face-to-face intake session with the e-Coach will take place for the participants assigned to the experimental group (week 4 to 10). Afterwards, a vaccination session will take place, immediately followed by a test day (after 10 weeks). Finally, a follow-up session will take place after 14 weeks.
Onderzoeksproduct en/of interventie
This randomized trial involves a psychological training aimed at optimizing immune function. After screening, subjects are randomized to a training (experimental group) or control condition. The training consists of an internet-delivered guided psychological training, based on cognitive-behavioral principles. The control condition will not receive any training.
The training period is followed by a vaccination with BCG as an immunological stressor.
One day after application of the BCG-vaccination, a test day is planned in which participants will be shortly exposed to psychological and physical stressors.
Finally, a follow-up session is planned at 4 weeks after vaccination.
