How to Prevent the Drop-Out: Understanding Why Adults Participate in Summative eHealth Evaluations.

The aim of this study was to investigate why adults participate in summative eHealth evaluations, and whether their reasons for participating affect their (non-)use of eHealth. A questionnaire was distributed among adults (aged ≥ 18 years) who participated in a summative eHealth evaluation. This questionnaire focused on participants' reason to enroll, their expectations, and on whether the study met their expectations. Answers to open-ended questions were coded by two researchers independently. With the generalized estimating equations method we tested whether there is a difference between the type of reasons in use of the eHealth service. One hundred and thirty-one adults participated (64.9% female; mean age 62.5 years (SD = 10.5)). Their reasons for participating were mainly health-related (e.g., being more active). Between two types of motivations there was a difference in the use of the eHealth service: Participants with an intellectual motivation were more likely to drop out, compared to participants with an altruistic motivation. The most prevalent expectations when joining a summative eHealth evaluation were health-related (like expecting to improve one's health). 38.6% of the participants said their expectation was fulfilled by the study. In conclusion, We encourage eHealth evaluators to learn about adults' motivation to participate in their summative evaluation, as this motivation is very likely to affect their results. Including altruistically motivated participants biases the results by their tendency to continue participating in a study.

Game not over: Explaining older adults' use and intention to continue using a gamified eHealth service.

BACKGROUND: Gamification within eHealth services can increase eHealth adoption. However, little is known about factors affecting adoption of gamified eHealth among older adults. In this study, we sought to explain the (continued) use of a gamified eHealth service among older adults (55+). METHODS: Participants used a gamified eHealth service, focusing on falls prevention, for 4 weeks and completed a post-test questionnaire based on the Technology Acceptance Model. We used Partial Least Squares Structural Equation Modeling to analyse our data. RESULTS: Seventy-two older adults participated with a mean age of 65.1 years (SD = 7.0). Our results show that first, perceived ease of use affected use of the service (use duration: ß = 0.303, R2 = 0.130, and use frequency: ß = 0.304, R2 = 0.107). Second, perceived usefulness affected the intention to continue using the service (ß = 0.754, R2 = 0.640). Third, use of the service did not predict the intention to continue using it. Furthermore, enjoyment affected perceived usefulness (ß = 0.783, R2 = 0.563) and aesthetics affected perceived ease of use (ß = 0.634, R2 = 0.652). CONCLUSIONS: This study refutes the expected relation between use and intention to continue use a gamified eHealth service. Additionally, we learned that using theoretical approaches focusing on technology acceptance, are not suitable for explaining (continued) use of gamified eHealth services.

Evaluation of a virtual coaching system eHealth intervention: A mixed methods observational cohort study in the Netherlands.

BACKGROUND: With the rise in human life expectancy, the prevalence of chronic disease has increased significantly. Adopting a healthy lifestyle can decrease the risk of chronic disease. Virtual coaching systems can help older adults adopt a healthy lifestyle.AimThe primary objective of this study was to assess the use, user experience and potential health effects of a conversational agent-based eHealth platform (Council of Coaches) implemented in a real-world setting among older adults. METHODS: An observational cohort study was conducted with older adults aged 55 years or older in the Netherlands. Participants were enrolled for 5-9 weeks during which they had access to Council of Coaches. They completed three questionnaires: pre-test, post-test, and at follow-up. After five weeks, an interview was conducted, and participants chose whether they wanted to use the eHealth intervention for another four weeks during the facultative phase. RESULTS: The study population consisted of 51 older adults (70.6% female) with a mean age of 65.3 years (SD = 7.4). Of these, 94.1% started interacting with Council of Coaches, and most participants interacted once per week. During the facultative phase, 21 participants were still interacting with Council of Coaches. Minimal clinical important differences in quality of life were found among the study population after interacting with Council of Coaches. CONCLUSION: Our results demonstrate that eHealth interventions with virtual coaching can be used among older adults. This may increase quality of life for older adults, and decrease their healthcare needs. Future research into such eHealth interventions should take into account the inclusion of sufficient personalised content and the use of a mixed methods study for assessing the eHealth intervention.

User Experience and Potential Health Effects of a Conversational Agent-Based Electronic Health Intervention: Protocol for an Observational Cohort Study.

BACKGROUND: While the average human life expectancy has increased remarkably, the length of life with chronic conditions has also increased. To limit the occurrence of chronic conditions and comorbidities, it is important to adopt a healthy lifestyle. Within the European project "Council of Coaches," a personalized coaching platform was developed that supports developing and maintaining a healthy lifestyle. OBJECTIVE: The primary aim of this study is to assess the user experience with and the use and potential health effects of a fully working Council of Coaches system implemented in a real-world setting among the target population, specifically older adults or adults with type 2 diabetes mellitus or chronic pain. METHODS: An observational cohort study with a pretest-posttest design will be conducted. The study population will be a dynamic cohort consisting of older adults, aged ≥55 years, as well as adults aged ≥18 years with type 2 diabetes mellitus or chronic pain. Each participant will interact in a fully automated manner with Council of Coaches for 5 to 9 weeks. The primary outcomes are user experience, use of the program, and potential effects (health-related factors). Secondary outcomes include demographics, applicability of the virtual coaches, and user interaction with the virtual coaches. RESULTS: Recruitment started in December 2019 and is conducted through mass mailing, snowball sampling, and advertisements in newspapers and social media. This study is expected to conclude in August 2020. CONCLUSIONS: The results of this study will either confirm or reject the hypothesis that a group of virtual embodied conversational coaches can keep users engaged over several weeks of interaction and contribute to positive health outcomes.

A Serious Exergame for Patients Suffering from Chronic Musculoskeletal Back and Neck Pain: A Pilot Study.

INTRODUCTION: Over recent years, the popularity of videogames has gone beyond youth and gamers and is slowly entering the field of professional healthcare. Exergames are an attractive alternative to physical therapy. The primary aim of this pilot study was to explore the user experience (usability, satisfaction, level of motivation, and game experience) of the patient with the "PlayMancer" exergame. The secondary aim was to explore the progression of the performed motor skills (walking velocity, overhead reach ability, and cervical range of motion) and the clinical changes (to physical condition, disability, and pain intensity) in a group of patients with chronic musculoskeletal pain using an exergame for 4 weeks. MATERIALS AND METHODS: In the European PlayMancer project, an exergame for physical rehabilitation of chronic pain patients was developed. This exergame is controlled by relevant motions of the patient's body captured by a motion suit and several infrared cameras. In three different integrated minigames, the patient can train the following motor skills: Walking velocity, overhead reaching, and neck mobility. RESULTS: Ten patients participated in this study and completed the 4 weeks of gaming. Patients rated the usability of the exergames as good (score of 78.5 [standard deviation 9.7; range, 60.0-97.5]) on the System Usability Scale, and the game motivated all patients to perform their exercises. Patients enjoyed playing and were pleased with both the game environment and the game play. Overall, the patients made a progression in the examined motor skills during the minigames over the 4 weeks of gaming. CONCLUSIONS: The "PlayMancer" exergame is a potential tool for achieving physical rehabilitation because it motivates patients to perform their exercises and as a result increases their motor skills and physical condition.

The clinical effectiveness of a myofeedback-based teletreatment service in patients with non-specific neck and shoulder pain: a randomized controlled trial.

We investigated the effectiveness and efficiency of a four-week myofeedback-based teletreatment service in subjects with non-specific neck and shoulder pain. Subjects were recruited in Belgium, Germany and the Netherlands and randomly allocated to the intervention or conventional care. Subjects in the intervention group received four weeks of myofeedback training. Pain intensity and disability were evaluated by questionnaires at baseline, immediately after four weeks of treatment and at follow-up 3 months later. To investigate efficiency, the time-investment of both therapists and patients were assessed. Seventy-one subjects were included in the study (36 in the intervention group and 35 in the conventional care group). Myofeedback-based teletreatment was at least as effective clinically as conventional care. Pain intensity and disability decreased after 4 weeks of treatment in both groups and part of the effect remained at 3 months' follow-up. The teletreatment also increased efficiency for therapists by almost 20% and patients experienced the benefits of less travel time and travel costs by remote consultation. Myofeedback-based teletreatment has the potential to ensure more efficient treatment for patients with non-specific neck and shoulder pain.

Relation between patient satisfaction, compliance and the clinical benefit of a teletreatment application for chronic pain.

We investigated the ease of use and usefulness as a measure of patient satisfaction, compliance, clinical benefit and its mutual relationships concerning a teletreatment application for chronic pain. Fifty-two subjects with neck and shoulder pain received and completed a four-week myofeedback-based teletreatment intervention. Prior to the onset of the intervention (at baseline) and immediately after the intervention they were asked to fill in questionnaires to measure discrepancies (gap scores) between expectations and experiences with the ease of use and usefulness of the treatment, as well as pain intensity and pain disability. In addition, the actual use of the system (i.e. the volume of muscle activity data available on the server) was logged. The subjects reported a significantly higher score on ease of use after the intervention compared to baseline, suggesting that the equipment was easier to use than they expected. Compliance was associated with clinical benefit. There was no significant relation between patient satisfaction and compliance. Patient satisfaction is a key indicator of how well the telemedicine treatment met expectations and compliance is important because of its association with clinical outcomes.

Prognostic factors for the effect of a myofeedback-based teletreatment service.

We investigated the potential prognostic factors for clinically relevant improvements in pain intensity and pain-related disability after myofeedback-based teletreatment. Sixty-five female computer users, 56 female patients with whiplash-associated disorders and 18 female patients with non-specific neck and shoulder pain participated in the study. They received myofeedback-based teletreatment or usual treatment. Questionnaires concerning prognostic factors, pain and disability were completed before the start of the intervention (baseline) and at follow-ups at the end of the intervention, and after 3 and 6 months. Logistic regression analyses were performed in order to investigate prognostic factors for clinically relevant improvement. In the intervention group, improvement in pain intensity was predicted by baseline pain intensity. Baseline pain intensity and disability, and fear-avoidance and endurance related pain coping responses were prognostic factors for outcome in pain-related disability in this group. There were few differences between the intervention groups; fear-avoidance coping responses influenced the outcome after teletreatment only. Myofeedback-based teletreatment appears to be an useful telemedicine intervention, especially for participants with moderate to high levels of pain and disability, high perceived help/hopelessness, and those who tend to deal with their pain by avoiding social and physical activities.
