Experience sampling methods for mental health research in intellectual disability2297awareness and receiving a gift-card. Drawbacks from participating were, among others, technical difficulties with the app or device, and irrelevance of the questionnaire items. Around half of the participants did not report any drawbacks.Based on interviews with adults with mild to moderate intellectual disability, Wilson and colleagues (2020) suggest that experience sampling is feasible for this population. Participants enjoyed taking part in the study and would be willing to participate in similar studies in the future. Reasons for noncompliance included being elsewhere with limited access to the device (e.g., at work), leaving the device somewhere else, not hearing the notification beeps, or technical difficulties with the device. In addition, participants and parents of participants provided recommendations for improving the feasibility of experience sampling applications, including the use of longer and louder prompts, use of specific language to avoid confusion about the questions, and include pictographs to aid understanding of the questions. In the study by Schneider et al. (2020), the researchers found that a subgroup of participants required additional monitoring during the study, but no further details were reported.Interview findingsSeven adults with mild intellectual disability tested existing experience sampling applications for three consecutive days, receiving four to five prompts per day, and were interviewed afterwards about their experiences. An additional focus group was held with four participants. The interviews were coded using thematic analysis, following Braun and Clarke (2006). Three main themes were predefined based on three domains of access to care as described by Levesque et al. (2013): acceptability (sub-themes: value and usefulness, and practical feasibility), availability (sub-themes: installation and registration, language and text, and response scales), and appropriateness (sub-themes: adapting the experience sampling design and the questionnaire response scales to the needs of users). Table 3 presents an overview of the themes and sub-themes, including examples of codes.Annelieke Muller sHL.indd 229 14-11-2023 09:07
