They filled out a digital questionnaire at the beginning of the study, after 4 months, and after 12 months. One questionnaire included possible determinants for adoption and effect of self-tracking devices (like personal variables, self-regulation for health, and motivation towards self-tracking). \\ |

| ===== Variables ===== | ===== Variables ===== | ||
| - | The questionnaires included questions about [[self-regulation]] and [[subjective health (general)|perceived health]]. In addition, the following variables were collected: | + | The questionnaires included questions about intention to start with self-tracking, and intention to change weight, sleeping behavior and physical activity behavior. In addition, attitude, self-efficacy and social norm towards self-tracking, [[self-regulation]] for health and [[subjective health (general)|perceived health]] were measured.\\ |
| + | Weight and self-weighing frequency were calculated using the weight self-measurements the participants conducted.\\ | ||
| + | After 4 and 12 months of self-tracking, the participants filled out an evaluation questionnaire in which they could indicate their experiences with the devices, and whether they had changed their physical activity behavior and eating habits.\\ | ||
| + | |||
| + | ===== Findings ===== | ||
| + | |||
| + | Most participants were satisfied with the self-tracking devices, although the usage of the devices declined over time. Usage of the weight scale stabilized after 3 months of self-tracking.\\ | ||
| + | The Pulse activity tracker gave some technical problems, like a short battery life, and was therefore replaced until 6 months after the start of the study in at least 30 participants. Thereafter, no replacement was possible due to a restricted availability of the tracker.\\ | ||
| + | About 40% of the participants indicated to have changed their eating habits, and 60% indicated to have increased their physical activity behavior.\\ | ||
| + | On average, the participants lost 2 kg after 4 months, which was remained after 12 months. An increase in self-regulation capabilities (goal-orientation after 4 months and decision-making after 12 months) explained this weight loss, next to intention to change weight and self-weighing frequency.\\ | ||
