Abstract

Objectives

To improve and promote mobile health monitoring services, this study investigated the perception of various factors influencing the acceptance of services between users and non-users.

Methods

This study drew 9 variables from studies related to mobile health monitoring services and the unified theory of acceptance and the use of technology model. A total of 219 samples were collected by a paper-based survey from users (n = 106) and non-users (n = 113). Analysis was carried out using a two-independent samples t-test.

Results

The findings indicate that users have a more positive perception of service benefits than non-users. Although there were difference between users and non-users, all respondents had a positive perception of the service benefits. After users used the service, they were less concerned about the risks involved with it. However, both users and non-users had a high negative perception of service risk. Users also had a more positive perception of intimacy and communication associated with the services than non-users. Both users and non-users had a high behavioral intention to use the services. Finally, this study observed that older subjects tended to recognize the higher value of the services.

Conclusions

This study provides insights to improve and invigorate mobile health monitoring services. This study also offers insights into how to increase the number of users of mobile health monitoring services in South Korea.

Keywords: Mobile Health, Telemedicine, Telehealth, UTAUT Model

I. Introduction

The concern and payment of medical service has hugely increased; therefore, the market for medical services has grown [1]. Along with adaptation of information technologies, such as ubiquitous and cloud computing, medical services have been changing from medical care to health management and illness prevention. Following this shift, telemedicine has been developing in a variety of fields. Most of all, mobile health monitoring services have attracted interest and have a potential for growth. Mobile health monitoring services related to health management and illness prevention could be provided. Such mobile health monitoring services could be highly effective, especially for chronically ill patients or people who want to manage their health and avoid illness [2]. Mobile health monitoring services have been defined as a combination system of mobile computing, medical sensors, and communications technologies for healthcare. Although, mobile health monitoring services have growth potential [3], it is limited by laws in South Korea [4].

In South Korea, telemedicine service acceptance has been driven by the Korean government [5]. Many issues must be solved; thus, it has not reached the stage of commercialization yet. Although there are obstacles that must be overcome before mobile health monitoring services can reach a more active stage of development, it could provide comprehensive medical care for chronically ill patients as well as healthy people. Therefore, many studies should be carried out. However, very few studies related to the users' perspective on mobile health monitoring services in South Korea [6,7]. To provide appropriate mobile health monitoring services, the system should be designed considering the perceptions and factors influencing mobile health monitoring service acceptance. Therefore, this study focused on public perceptions of mobile health monitoring services.

This study attempted to determine the importance of real service usage and service awareness to service users. This study investigated the user's perspective on mobile health monitoring services. The objectives of this study may be summarized as follows. This study aimed to discover the various perceptions of factors influencing the acceptance of mobile health monitoring services of users and non-users. By revealing the perceptions of mobile health monitoring service users and non-users, this study can provide understanding and insight into the needs and desires of users. Moreover, the study can provide a practical guideline for the design and development of mobile health monitoring services by service providers and policy makers.

1. Theoretical Background

1) Patients' perception in telemedicine service acceptance

To understand patients' perception influencing telemedicine service acceptance, a literature review was conducted related to telemedicine service acceptance. Through the literature review, this study finally found four perceptions: communication, accessibility, intimacy, and service risk. This study classified the four perceptions into three categories concerning the patients' core perception in telemedicine service acceptance, namely, 1) benefit factors, 2) benefit & disadvantage factors, and 3) disadvantage factors.

According to literature review, patients perceived that using telemedicine services would help them to improve their health condition [8-11] and that it would provide health records or health care unbound by time and space [12-17]. In addition, patients perceived that using telemedicine services would involve communication with the service provider, hospital staff, clinical institution, and other users, and they had a sense of intimacy between patients and providers through sympathy, confidence, and respect; however, they also expressed concern over these factors [11-13,18,19]. On the other hand, they were worried about uncertainty of telemedicine services [20-22]. Table 1 summarizes patients' perception in telemedicine service acceptance.

2) Unified theory of acceptance and use of technology

This study accepted constructs as basic perceptions influencing the acceptance of mobile health monitoring service in order to complement patients' positive perception in mobile health monitoring service acceptance. Therefore, this study adopted four constructs from the unified theory of acceptance and the use of technology (UTAUT) model proposed by Venkatesh et al. [23] because the UTAUT model could provide robust understanding for users' technology acceptance [24].

As noted above, the UTAUT model comprises four significant constructs, namely, performance expectation, effort expectancy, social influence, and facilitation conditions. Performance expectation in the UTAUT model has the same meaning as perceived usefulness in the technology acceptance model (TAM). Effort expectancy is the same as the perceived ease of use in TAM [25]. Social influence means the degree to which an individual perceives it to be important that others believe he or she should use the new system. Facilitating conditions refer to the degree to which an individual believes that an organizational and technical infrastructure exists to support the use of the new system [23].

The UTAUT model has some advantages. First, although there are various versions of users' technology acceptance model, such as TAM and TAM2, the UTAUT is a comprehensive model to explain the user's usage intention and actual usage in the information system. The UTAUT was developed by considering eight previously developed models, namely, the theory of research action, TAM, the motivational model, the theory of planned behavior (TPB), combined TAM and TPB, the model of PC utilization, the innovation diffusion theory, and social cognitive theory. Second, the UTAUT model explained 69% of intention to use IT, while other models explained approximately 40% of technology acceptance [23].

Among the many studies related to technology acceptance, the UTAUT model had also been frequently used in the healthcare field [26-31]. Nwabueze et al. [24] used the UTAUT model to find that cultural characteristics are important factors in the adoption of telemedicine service. Cranen et al. [32] used a qualitative framework based on the UTAUT to recognize patients' perceptions regarding telerehabilitation services and the factors that facilitate or prevent patients' intentions to use.

To accept four constructs as patients' perceptions influencing mobile health monitoring service acceptance, this study modified four constructs based on literature review related to telemedicine service. Accordingly, this study drew positive factors influencing mobile health monitoring service acceptance by patients from studies based on the UTAUT model.

II. Methods

1. Instrument Development

Firstly, this study conducted a literature review to derive basic perceptions influencing the acceptance of mobile health monitoring services. We found four perceptions: communication, accessibility, intimacy, and service risk. As previously mentioned, the four perceptions were categorized in terms of three categories concerning the patients' core perception of the advantages and disadvantages of telemedicine services: 1) factors for which telemedicine is perceived positively are considered benefit factors, 2) those for which it is perceived both positively and negatively are considered benefit & disadvantage factors, and 3) those factors for which telemedicine is perceived negatively are considered disadvantage factors. Secondly, this study adopted four constructs from the UTAUT model, to complement patients' positive perceptions in the mobile health monitoring service acceptance. All constructs were adopted from prior studies related to the UTAUT, with necessary validation and wording changes tailored to the telemedicine service and healthcare context. Table 2 summarizes the definitions of the constructs based on nine factors from the literature review. All questions were measured using a seven-point Likert scale with answers from "strongly agree" to "strongly disagree".

2. Sample and Data Collection

Data were collected from the users group and the non-users group in relation to mobile health monitoring services. A survey was conducted for eight weeks, from March 5, 2012 to April 28, 2012. The survey was administered separately to users and non-users. First, the survey of the users group was conducted at Changwon City Health Center. Changwon City Health Center provided a mobile health monitoring service to prevent diseases of the local population. This service was provided with support from the Korean government, from February to December in 2012. This mobile health monitoring service provided care in areas, such as nutrition and exercise management. Through this service, participants could use a 'pedometer,' to record health information. Users could update their health information, such as body composition analysis, activity, and other personal health information. There were three health zones where health information readers were installed around Changwon City. If a user placed the 'pedometer' they had used on the health information reader, their health information was sent to the health service center. Users could manage comprehensive health care through the Website. Their health information was then managed by a trainer, nutritionist, and nurse. Users could receive telephone and SMS counseling, and they received health analysis reports by e-mail and post each month. After the users agreed to participate in our survey, paper-based questionnaires were administered. Two-hundred questionnaires were distributed. The survey finally yielded 106 usable responses from the users group. Second, the survey for the non-users group was conducted at six university hospitals. Five of these hospitals were located in Seoul, and the other was located in Daegu City. After the patients agreed to participate in the survey, paper-based questionnaires were administered. Questionnaires were collected from 200 outpatients. The survey finally yielded 113 usable responses from the non-users group.

3. Statistical Analysis

SPSS ver. 18.0 software (SPSS Inc., Chicago, IL, USA) was used for this study. First, this study performed exploratory factor analysis to find discernible construct structures. Next, a principal component analysis with varimax rotation was performed. Second, this study assessed the reliability of all constructs using Cronbach's alpha. Third, before the analysis of different perception among users and non-users, a two-independent samples t-test was carried out with the focus on gender. Also, a one-way ANOVA analysis was carried out in relation to age using nine variables. Finally, a two-independent samples t-test was carried out focused on users (n = 106) and non-users (n = 113) depending on the perception of influencing factors on the acceptance of mobile health monitoring service.

III. Results

1. Sample Characteristics

Table 3 summarizes the profile of the 219 respondents. Among all respondents, 106 respondents (48.4%) had experience with mobile health monitoring service, while 113 respondents (51.6%) had no experience with mobile health monitoring service. A total of 61.2% of the respondents were women. Of the 219 respondents, 144 respondents (65.7%) were over 50 years old. Only 29 respondents (13.2%) had no disease. The rest of the respondents who had a disease mostly had hypertension (34.7%) and diabetes (30.6%).

2. Reliability and Validity

Before the analysis, the construct validity and internal reliability was tested. First, an exploratory factor analysis was performed to test the construct validity. A principal component analysis with varimax rotation was carried out for each construct. All factors emerged with no-cross construct loadings above 0.50. The pattern of loadings and cross-loadings supported discriminant validity and internal consistency [35]. The instrument also demonstrated a convergent validity with factor loadings that exceeded 0.50 for each construct. The results showed the existence of all factors with eigenvalues greater than 1.0 that accounted for 80.031% of the total variance. In addition, communality ranged from 0.665 to 0.990. Therefore, all items achieved the 0.50 threshold [36]. Thus, these results demonstrated that all constructs were distinct uni-dimensional scales.

Next, the use of Cronbach's alpha was evaluated for internal consistency reliability [37]. The values for all constructs ranged from 0.871 to 0.965. Since the values for all constructs were greater than 0.70 [35], Cronbach's alpha was reliable for all constructs. Table 4 summarizes the results of the reliability and validity analysis.

3. Different Perception in Demographic Factors

Before the analysis of different perceptions among users and non-users, a two-independent samples t-test was carried out with the focus on gender (Table 5). First, the mean score was found to be higher in females than in males with respect to nine variables. The results indicate that there is a significant difference between males and females regarding the behavioral intention to use (t = -2.339, p < 0.05), effort expectancy (t = -2.015, p < 0.05), and intimacy (t = -2.772, p < 0.01).

Second, a one-way ANOVA analysis was conducted in relation to age using nine variables (independent variables). The results of this analysis demonstrated that perceptions of accessibility differed with age (F(3, 215) = 6.67; p = 0.001). Post hoc comparisons were then performed using a Scheffe test, which showed significant paired comparison only for 20-39 years versus 40-49 years (p = 0.001) (Table 6). The results from the one-way ANOVA analysis also demonstrated that facilitating conditions differences were dependent on age (F(3, 215) = 2.78; p = 0.042). Post hoc comparisons were then performed using a Scheffe test, which did not show significant paired comparison in relation to age.

4. Perception Differences between Users and Non-users

A two-independent samples t-test was carried out focused on users (n = 106) and non-users (n = 113) in relation to the perception of influencing factors on the acceptance of mobile health monitoring service.

Firstly, a two-independent samples t-test was conducted regarding perceived benefits, such as performance expectancy, effort expectancy, facilitating conditions, social influence, and accessibility. The results in Table 7 show that the 5 constructs' mean score related to users, who had an experience of mobile health monitoring service, were higher than the non-users' mean score. The results showed significant differences between users and non-users regarding performance expectancy (t = 3.499, p < 0.001), effort expectancy (t = 5.009, p < 0.001), social influence (t = 6.205, p < 0.001), and facilitating conditions (t = 4.161, p < 0.001). There was no significant different between users and non-users regarding accessibility.

Secondly, this study conducted a two-independent samples t-test regarding perceived risk, such as service risk (Table 7). For non-users, the mean score for service risk was higher than that of users; the results showed a significant difference between users and non-users regarding service risk (t = -5.013, p < 0.001).

Thirdly, a two-independent samples t-test was carried out regarding communication and intimacy, which are considered both perceived benefits and perceived risks. The results in Table 7 showed that 2 constructs' mean score related to users, who had experience of telemedicine, were higher than the non-users' scores. The results showed a significant difference between users and non-users regarding communication (t = 4.790, p < 0.001) and intimacy (t = 5.015, p < 0.001).

Finally, the mean score of behavioral intention to use related to users, who had an experience of mobile health monitoring service, was higher than the non-users' score (Table 7). The results showed a significant difference between users and non-users regarding behavioral intention to use (t = 5.569, p < 0.001).

IV. Discussion

This study investigated the perception of various factors influencing the acceptance of mobile health monitoring services between users and non-users. Based on the results of this study, the following conclusions may be drawn.

First, the users group had a more positive perception of service benefits than the non-users group. However, there was no difference in perceptions of accessibility. Although there were significant differences between the perceptions of the users group and the non-users group, all respondents had a positive perception of service benefits [13,20,21,33,34]. In other words, people had positive expectations for mobile health monitoring services.

Second, after people used mobile health monitoring services, they were less concerned about service risks, such as cost and service quality. However, both the users group and the non-users group had high negative perception of service risk [21].

Third, the users group had a more positive perception of intimacy and communication than non-users. There were additional differences between the users group and the non-users group. These results showed that users felt that mobile health monitoring services created relationships between patients as service providers that were sympathetic, confident, and respectful [13,20,34]. They could communicate with service providers, hospital staff, clinical institutions, and other users.

Fourth, both the users group and the non-users group had high behavioral intention to use. In other words, people had high demand for mobile health monitoring services.

Finally, there are some differences related to age and gender. Females had a positive perception of behavior intention to use, effort expectancy, and intimacy. People in their forties perceived the mobile health monitoring services more positively regarding accessibility than younger people. This result confirmed that, to users, it was important to not only know about mobile health monitoring service, but also experience the service. Therefore, service providers primarily should publicize the advantages associated with mobile health monitoring service. This promotion could serve to allay users concerns about service risks, such as cost and service quality. Furthermore, service providers should encourage service users feel comfortable and confident about service quality and usage. To do that, they should provide a lot of assistance, guidelines, and education. Providers should create opportunities for the public to experience their services, such as the mobile health monitoring service pack and trial period service. Mobile health monitoring service devices should be designed so that they are compatible with familiar devices, such as cellular phones and smartphones. In addition, mobile health monitoring services should be designed with consideration of the age of many people.

There were two main limitations of this study. First, females were over-represented in the respondent groups. Among the respondents, those who were 50-59 years of age comprised about 42.0%. Future studies should collect data following the gender and age ratios of the general population.

Second, among the respondents, only 29 respondents (13.2%) had no disease. The remainder of the respondents who had a disease mostly had hypertension (34.7%) and diabetes (30.6%). Future studies should design be designed to focus on patients with specific medical conditions.

Third, the surveys of the users group and the non-users group were conducted at different types of health care institutions, that is, Changwon City Health Center and university hospitals. Future studies should design the surveys to be conducted at the same types of medical institutions.

Although this study had some limitations, this study yielded some valuable implications. To our knowledge, there have been no previous studies conducted on the perception of various factors influencing the acceptance of mobile health monitoring services between users and non-users in South Korea. This study also provides insight and practical guideline to enhance and promote mobile health monitoring services.
