Experience sampling methods for mental health research in intellectual disability2237were specific to the experience sampling questions and response scales (Likert response scale or visual-analogue scale), such as: the clarity of the questions; how participants experienced giving a grade to their feelings (visual-analogue scale) or choosing an answer to indicate how they were feeling (Likert response scale); and if participants would have preferred emoticons or other images as response options. The third set of questions directly regarded the feasibility and usefulness of the application, such as: if participants found the application useful for assessing their own mood and feelings; what they would change or improve about the app; and if they would like to use the app in the future. The interviews were audio recorded, transcribed verbatim, and anonymised before analysis.Focus group. A focus group consisting of four participants was organised to gather additional views on design choices of experience sampling apps. Participants were asked to imagine that they would develop an experience sampling app that would be used by themselves and other individuals with intellectual disability, in the context of mental health research. They were asked what the application would look like, if emoticons or other images should be used, if a reward system (e.g., collecting points) would help completing the questionnaire, what kinds of questions they would include, what the response scales should look like, and what other design choices they would find important.ProcedureParticipants were recruited via the experts-by-experience team from ‘s Heeren Loo. Information letters and informed consent forms in accessible language were shared with the coaches of the participants, who then shared these materials with them. After informed consent was obtained, individual meetings were scheduled with participants and their coaches to get to know the researchers, to allow participants to ask questions about the study, and to schedule the testing days and debriefing interviews. After the first meeting, participants installed the applications on their smartphone, independently or with help from their coach. Each participant tested two applications for three days, with at least seven rest days in between the two testing periods. During the testing days, participants were prompted five times to complete a five-minute questionnaire. The fifteen-minute debriefing interviews took place as soon as possible after the last testing day, to reduce memory bias. Annelieke Muller sHL.indd 223 14-11-2023 09:07
