24-hour Movement Behaviors Among Type 2 Diabetes Mellitus Patients

During their visit to Ghent University hospital, participants will receive a wGT3X-BT ActiGraph accelerometer that will objectively measure their 24-hour movement behaviors (PA, SB, and sleep). The participants will wear the accelerometer for seven consecutive days. Additionally, this accelerometer data will be supplemented with a diary to validate sleep time and (non)wear time. Furthermore, the individuals will subjectively report on their PA, SB, and sleep (duration and quality) through an online questionnaire based on international standardized PA (IPAQ), SB (SIT-Q-7d), and sleep questionnaires (Munich Chronotype questionnaire, Pittsburg sleep quality index, and Sleep Hygiene Index) (IPAQ, Sit-7Q, Munich Chronotype questionnaire, and Pittsburg sleep quality index, Sleep Hygiene Index). By collecting the same variable on three timepoints, it is possible to determine if this outcome will change or remain stable over time.

A new questionnaire has been developed and is currently at the final stage of testing the test-retest reliability. This questionnaire questions the behavioral factors included within the integrated behavior change model i.e. autonomous motivation, attitude, self-efficacy, subjective norm, internal control and external control. A higher score means a behavior factor that positively relates to the health behavior. Furthermore, the cut-off point for the behavioral factors will be determined by the cumulative percentage. In addition, by collecting the same variable on three timepoints, it is possible to determine if this outcome will change or remain stable over time.
