Feasibility and effects of an eHealth intervention to support patients with a low socioeconomic position during their waiting period preceding cardiac rehabilitation 123 6 Figure 6.4 Cumulative messages completed vs days since the first usage (Median ± IQR). 6.3.3 Acceptance of the intervention Seventy-one per cent of the participants displayed overall positive acceptance. We found that 86% of the participants were positive about the intervention’s usability, and 67% were satisfied. Forty-three per cent felt that the intervention was useful for them (see Table 3 for a complete overview of the acceptance scores). Within the qualitative data, we found that participants mainly appreciated the ease of use and the playful interface. As one participant expressed: “Well, you know, I found it enjoyable. It’s more enjoyable than just a boring list or something, you know. Yeah, it’s funny that they thought of it like, oh yeah, let’s pretend it’s a journey. With your stories in a suitcase, very amusing. You’re on a journey to your rehabilitation.” [Female, 60] We also found qualitative themes that related to the usefulness. More than half of the participants suggested the need for more personally relevant information better aligned with their health concerns and the severity of their conditions. As one participant expressed: “All those social workers and such... For me, I think it’s not interesting. I only do it to become physically well. That’s my goal. I don’t think I have any other issues. I think the app is limited in that aspect.” [Male, 76]
