Chapter 7228were people with mild intellectual disability3 or mild intellectual disability/borderline intellectual functioning.25,26 Sample sizes of the included studies ranged between 1-107 participants.Synthesis of resultsThe study aims and findings regarding the compliance, drop-out rates, and acceptability and feasibility of experience sampling are reported in Table 2.In two studies,3,25 the acceptability and feasibility of experience sampling were the target outcomes. In the other studies, experience sampling was used to investigate social and/or psychological outcomes. Compliance rates were reported by five studies3,22,24–26 and ranged between 34%3 to 95%. 22 Feller et al. (2021; 2023) reported that the researchers sent personalised messages to the participants every other day to encourage them and to verify study compliance, and that the researchers were available for support throughout the experience sampling procedure. The authors suggested that the high compliance in their study may be due to the guidance of the researchers during the study period. In four of the included studies,21–24 participants were excluded from the study because compliance was below 33%.Findings regarding the acceptability and feasibility of experience sampling were reported by three studies.3,24,25 Hulsmans et al. (2023) concluded that daily experience sampling is feasible for adolescents and young adults with mild intellectual disability and borderline intellectual functioning, based on compliance (70%) and drop-out (26%) rates. Based on interviews, they further concluded that experience sampling is acceptable for this population. The findings suggest that using one’s own device (instead of a device shared by a group of participants) for completing the diary is important for compliance with the study protocol. Reasons for non-compliance included, among other reasons, forgetting to fill in the diaries, being in the company of other people, and experiencing high levels of stress. More reminders by care professionals and the application to fill in the diary would have helped participants to increase their compliance. The study duration of 60 days and one prompt per day were appropriate for most participants (69% and 73% of participants, respectively). Further, participants reported gains from participating, the most prominent ones were increased selfAnnelieke Muller sHL.indd 228 14-11-2023 09:07
