The Effectiveness of an Online Health Training on Optimizing Health in a Healthy Population

INTERVENTION: A randomized controlled between‐subjects design will be applied. Participants are randomly allocated to one of two groups: the Experimental group will receive the online health training of 2 weeks duration, while the Control group serves a no‐treatment control group. Participant health parameters will be measured three times: at baseline, after 2 weeks, and at follow‐up after four weeks. CONDITION: Online Learning ; ; PRIMARY OUTCOME: The primary outcome measure is vitality, which consists of the standardized (z‐scores) of the SVS and CIS. SECONDARY OUTCOME: Secondary study parameters include self‐reported psychological outcome measures assessed at baseline, after 2 weeks, and after 4 weeks. INCLUSION CRITERIA: 1. Healthy adults (based on demographic questions). 2. Between the ages of 18 and 35 years old. 3. A score of < 5 on the Subjective Vitality Scale (SVS: Ryan & Frederick, 1997) and/or a score of > 17 on the Checklist Individual Strength‐Fatigue Severity Scale (CIS: Vercoulen et al., 1994).
