Conditions
Interventions
For study 1 the intervention will be as follows:
The participant will be asked to walk from (A) to (B) in exactly X seconds, wearing scuba fins and a blindfold. The number of seconds that the subject
only physical activity is measured. After these seven days, participants come to RRD so that the principal investigator can adjust the AAF's settings according to the participants assigned condition.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main outcome parameter for study 1) and study 2) is level of Self-efficacy. For study 1), Self-Efficacy will be measured by asking subjects, before each trial, how confident one is that one can execute the required task on a scale of 0 to 100. In study 2), Self-Efficacy will also be measured by the adapted version of the questionnaire by Rodgers et al. Subjects, however, will be asked to answer the questionnaire at two points in time: at the start of the experiment and at the end. | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary outcome parameters for study 1) are: - Task performance: the number of seconds that the subject deviates from the number of seconds the subject was given to complete the trial. Analyzed as a quantitative variable, using a univariate analysis of variance. - Level of Self-Efficacy at the end of the experiment as measured by the question that subjects have to answer at the start of each trial. - Level of Self-Efficacy as measured by the adapted version of the questionnaire by Rodgers et al. (2008). - Retention rate will be calculated by subtracting the average performance on the retention trials from the average performance on the experimental trials. The differences between groups in retention rate can be investigated using a univariate analysis of variance. The secondary outcome parameters for study 2) are: - Change in activity: the rate of change in physical activity pattern for 30 minutes after a feedback message has been presented to the subject. Our research design only allows for comparing condition 1 and 2, since subjects in group 3 will not receive any feedback messages. Subjects will be asked whether they smoke or not and what their working status is to identify a possible influencing factor (see Appendix 3). - Stage of Change: a one item questionnaire is used to assess a subject’s stage of change. Based on the answer the subject can be categorized in one of five stages: precontemplation, contemplation, preparation, action or maintenance. Subjects will be asked to complete this questionnaire both at the start and the end of the experiment. | — |
