Convergent Validity of DABQ Questionnaire

"In this study, participants will have one contact session with the researcher, which will be held either at Ghent University Hospital or at the participants' home. During this session, participants will be provided with an accelerometer device and two questionnaires (to be filled in after wearing the Actigraph), namely the Daily Activity Behavior Questionnaire (DABQ) and general information questionnaire.~The participants will receive an Actigraph wGT3X+BT accelerometer which will be worn for seven consecutive days. Instructions will be given on how to wear the accelerometer (e.g. during the day at the hip and during the night at the wrist). At the end of this week, the participants will fill in both questionnaires. After wearing the accelerometer for seven consecutive days and filling in both questionnaires, the researcher will visit the participants to collect the devices, or the participants will send them back by postal package."
