Treating Depression with a Behavior Change Support System without Face-to-Face Therapy

In this paper, we present results from a randomized controlled trial (RCT) that examined the impact of persuasive reminders and virtual rehearsal on the effectiveness of a behavior-change support system (BCSS). We developed the Web-based BCSS to support people with mild to moderate depression without face-to-face therapy. We randomized eligible participants into two groups. Both groups rehearsed the target behavior virtually; however, only the first intervention group received email-based reminders. We applied a mixed-methods approach for the analysis. We collected data with semi-structured self-reported questionnaires and post-study interviews. Results indicate that the severity of depression was noticeably decreased and participants’ self-confidence to manage depressive thoughts was generally improved. The influence of persuasive reminders on task completion was less than we anticipated, while the participants felt that virtual rehearsal was an effective technique for learning new behaviors. We discuss possible reasons for the results at the end of the paper

Application of Mobile Health Services to Support Patient Self-Management of Chronic Conditions

Background: Chronic conditions are the leading cause of ill-health, disability and premature death, adding huge health and socioeconomic burden to the healthcare system. Although mobile health (mHealth) services have the potential to provide patients with a timely, ubiquitous, and cost-effective means to access healthcare services, to date, much remains to be revealed for their application in chronic condition management. Aim: This doctoral project aims to comprehensively understand the application of mHealth services to support patient self-management of chronic conditions. This aim is achieved through four objectives: (1) to synthesise research evidence about health outcomes of applying mHealth services to support patient self-management of chronic conditions and the essential components to achieve these outcomes, (2) to determine the mechanism for applying mHealth services to support patient self-management of chronic conditions, (3) to explore critical factors and how these factors influence patients\u27 intention to continuously use mHealth services, and (4) to apply the above findings to guide the design of a prototype mHealth service. Methods: To increase the generalisability of the findings, three chronic conditions that could benefit from mHealth services were purposively studied to address the research objectives within the feasibility of available study sites and resources at different stages of the project. First, two literature review studies were conducted to achieve Objective 1. One was a systematic review to investigate health outcomes of mHealth services to support patient self-management of one chronic condition, unhealthy alcohol use, and the essential components to achieve these outcomes. The other was a rapid review on using behavioural theory to guide the design of mHealth services that support patient self-management of another chronic condition, hypertension. Second, two field studies were conducted to achieve Objectives 2 and 3, respectively. One was an interview study that explored patients\u27 perceptions of a mHealth service to support their self-management of hypertension in China. The other was a questionnaire survey study conducted on the same site that explored critical factors influencing patients\u27 intention to continuously use the mHealth service. Third, a clinician-led, experience-based co-design approach was implemented to apply the above-mentioned learning experience to the development practice of a mHealth service that supports patient self-management of obesity before elective surgery in Australia, achieving Objective 4. Results: Literature reviews identify five structural components - context, theory, content, delivery mode, and implementation procedure - which are essential for mHealth services to achieve three health outcomes - behavioural, physiological, and cognitive outcomes. Inductive synthesis of the interview findings lead to a 6A framework that summarises the mechanisms for mHealth services: access, assessment, assistance, awareness, ability, and activation. Mobile health services provide patients with easy access to health assessment and healthcare assistance to increase their self-management awareness and ability, thereby activating their self-management behaviours. Questionnaire survey study finds that patients\u27 intention to continuously use mHealth services can be influenced by the information quality, system quality and service quality by influencing their perceived usefulness and satisfaction with the mHealth services. Guided by Social Cognitive Theory, the developed prototype mHealth service provide patients with functions of automatic push notifications, online resources, goal setting and monitoring, and interactive health-related exchanges that encourage their physical activity, healthy eating, psychological preparation, and a positive outlook for elective surgery. The patients\u27 requirements in two focus group discussions enabled the research team to improve the mHealth service design. Conclusion: Mobile health services guided by behavioural theories can provide patients with easy access to health assessment and healthcare assistance to increase their self-management awareness and ability, thereby activating their self-management behaviours. The effort for designing mHealth services needs to be placed on crafting content (to improve information quality), developing useful functions and selecting a proper delivery mode (to improve system quality), and establishing effective implementation procedures (to improve service quality). These will ensure patients\u27 perceived usefulness and satisfaction with mHealth services, increase their intention to continuously use such services, thus supporting long-term patient self-management of chronic conditions. As demonstrated by the design case, the findings of this PhD project can be generalised to guide the design of other mHealth services that aim to support patient self-management of chronic conditions

Establishing Design Principles for Augmented Reality for Older Adults

Augmented Reality (AR) is growing rapidly and becoming a more mature and robust technology, which combines virtual information with the real environment in real-time. This becomes significant in ensuring the acceptance and success of Augmented Reality systems. With the growing number of older mobile phone users, evidence shows the possible trends associated with using AR systems to support older adults in terms of transportation, home activities, rehabilitation training and entertainment. However, there is a lack of research on a theoretical framework or AR design principles that could support designers when developing suitable AR applications for specific groups (e.g. older adults). This PhD research mainly focuses on the possibility of developing and applying AR design principles to provide various possible design alternatives in order to address the relevant AR-related issues focusing on older adults. This research firstly identified the architecture of Augmented Reality to understand the definition of AR using a range of previous AR examples. Secondly, AR design principles (version 1) were identified after describing the AR features and analysing the AR design recommendations. Thirdly, this research refined the AR design principles (version 2) by conducting two half-day focus groups with AR prototypes and related scenarios for older adults. The final version of the AR design principles (version 3) for older adults was established. These are: Instantaneous Augmentation, Layer-focus Augmentation, Modality-focus Augmentation, Accurate Augmentation and Hidden Reality. Ultimately, all of these design principles were applied to AR applications and examined in practice using two focus groups. Additionally, as part of the process of AR principle development, a number of AR issues were identified and categorised in terms of User, Device, Augmentation, Real Content, Interaction and Physical World, based on the pre-established AR architecture. These AR issues and design principles may help AR designers to explore quality design alternatives, which could potentially benefit older adults

The technology acceptance of a TV platform for the elderly living alone or in public nursing homes

In Mexico, many seniors are alone for most of the day or live in public nursing homes. Simple interaction with computer systems is required for older people. This is why we propose the exploration of a medium well known by seniors, such as the television (TV). The primary objective of this study is to improve the quality of life of seniors through an easier reminder system, using the television set. A technological platform was designed based on interactive television, through which seniors and their caregivers can have a better way to track their daily activities. Finally, an evaluation of the technology adoption was performed with 50 seniors living in two public nursing homes. The evaluation found that the elderly perceived the system as useful, easy to use, and they had a positive attitude and good intention to use it. This helped to generate initial evidence that the system supported them in achieving a better quality of life, by reminding them to take their medications and increasing their rate of attendance to their medical appointments

i ErgoApps : A mobile application that create awareness and reminder on having ergonomic practices to avoid Work Related Musculoskeletal Disorders (WMSD).

Occupational accidents and diseases keep consistently high and increasing in numbers. The stem of the diseases and accidents are from a lack of attention to ergonomics in the workplace. Nowadays, practicality during applying tasks in workplace where most people work is less focused rather than on research and high technology. Despite the application of ergonomic principles have great potential in improving productivity and the condition of workplace, but it still getting less attention from respective individual in charge especially in Malaysia. To date, the application and principles still reached only a limited number of workplaces among Malaysian employers and employees. To make it worse, the negative effect of not practicing ergonomic practices are Work Related Musculoskeletal Disorders (WMSD) like carpal tunnel syndrome, repetitive stress injuries, and back pain. WMSD are the main ergonomic diseases that need a high cost to deal with and Malaysian workers also never make a report on their ergonomic problem like minor symptoms of having ergonomic diseases. Another factor of lacking on ergonomic awareness were due to most small and medium industries had low capital and low budget constraints which disable them from hiring expertise or professional ergonomist to handle and ensure ergonomic improvements in their workplace. The lack of ergonomic awareness amongst Malaysian employees and employers may bring a long term negative effect to the firm’s productivity and performance. This may reduce the productivity of the country. Hence to overcome the problem, the objectives of the project are to identify the current ergonomic practice amongst Malaysian employees and then increase their awareness on the importance of having ergonomic practice in workplace via cost-effective mobile application in avoiding WMSD. The proposed system ErgoApps is a mobile application which has been developed parallel with the requirement and objective of OSHA and DOSH in ensuring occupants’ health and safety but at the same time able to conduct the tasks successfully. Several manuals in managing workspace devices focusing in office x and also ergonomic interventions like simple exercise after few hours of gap are presented in the system. The aim is to create positive effects without relying on costly and highly sophisticated solutions and also preventing WMSD. Realistic solutions are needed which can be applied in a flexible manner and contributes to improved working conditions and higher productivity. With that, the proposal of the project has been presented to the respective 110 respondent via pre-survey, and the final product being tested by the respective respondent via System Usability Scale with the compromising average score of 86.60% out of 100%. Since the respondents are from desk workers and staffs that highly involved with computer-related workload, they found that the application is very useful to be use daily during working time to enhance the efficiency and performance of their tasks. To add, the application also compliant with the rules embedded by DOSH, OSHA, and NIOSH in encouraging the employees to practice a safe working environment to avoid long-term negative effects in future which may involves dreadful cost in treating WMSD

Delivering elder-care environments utilizing TV-channel based mechanisms

In this paper, we present a smart environment for elderly. What makes the development of such system challenging is that the concept of smartness for elderly brings to the extreme the idea of invisibility of the technology. In our experience, elders are well-disposed to new technologies, provided that those will not require significant changes - namely, they are invisible - to their habits. Starting from this consideration, 200 caregivers responses were collected by questionnaire, so as to better understand elders' needs and habits. A system was subsequently developed allowing elders to access a number of "modern web services" as standard TV channels: at channel 43 there is the health status, at channel 45 the photos of the family, at 46 the agenda of the week, just to mention few of the available services. The content of such services is automatically generated by the smart devices in the environment and is managed by the caregivers (e.g., family members) by simple web apps. Fourteen families were asked to install the system in their house. The results of these experiments confirm that the proposed system is considered effective and user-friendly by elders
