| Sumario: | Purpose There is ample evidence of telehealth services being beneficial for managing patients with chronic diseases such as diabetes and hypertension. They do not only facilitate and im-prove data sharing and real-time communication between care professionals and patients with long-term conditions, but can also support patients' self-management of health that results in more safe and comfortable life at home over a prolonged period of time (Uei et al., 2017; Cartwright et al., 201 7; Dolnicar et al., 201 7). Surprisingly, there is a lack of research that would empirically investigate the relationships between acceptability, usability and the self-assessed benefits of telemonitoring systems (TMSs) for patients with chronic diseases (Goodwin, 201 0). Hence, this paper will present the results of an intervention study in Slovenia that explored how user experience (UX) of patients using home TMS affects their self-evaluation of its utilization over an extended period of time. Method Ninety-five patients with diabetes (n=1 7), or hypertension (n=54) or a combination of the two (n=33), defined as a primary disease, received the home TMS and tested it for 3 months. All participants (age range: 35-76 years) in the non-probability sample were recruited in a Health Centre by health professionals who actively participated in the intervention. The UX of the home TMS was evaluated with two standardized survey instruments (TUQ, SUTAQ), while the psychosocial impacts of TMS utilization were measured with the PIADS-10 questionnaire. Structural equation modelling was used to examine relationships between the perception of psychosocial impact of the TMS use, the evaluation of acceptability, usability and the intent for future TMS use, based on a theoretical model. Results and Discussion The study demonstrates that in our sample of patients with diabetes and/or hypertension, the psychological impacts of home TMS utilisation were influenced by its usability but not by its acceptability, regardless of patients' (control over) health and frequency of TMS use. The intent for future TMS use is directly influenced only by the usability of the service tested.
