Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main study parameter is the change in physical activity level. PA will be assessed using the validated self-administrated International Physical Activity Questionnaire (IPAQ). Every activity will be assessed in minutes per week, with a further distinction into moderate and heavy intensity. The IPAQ was proven a valid and reliable internationally accepted questionnaire. We will use the validated computerised Dutch version of the IPAQ. | — |
Secondary
| Measure | Time frame |
|---|---|
| Relevant PA related determinants will be measured using standard reliable scales and existing questionnaires: Stage of Change, intention, intrinsic motivation, the degree that participant’s s need for autonomy, competence and relatedness is met and commitment to physical activity. We will ask respondents for their appreciation, usefulness, readability, attractiveness, personal relevance, and understanding of the intervention. These measures are based on our previous computer tailoring evaluation studies. | — |
