Abstract The main focus of this study is the identification of factors influencing the use and effectiveness of information system development methodologies (Le., systems development methodologies) in health information systems. In essence, it can be viewed as exploratory research, utilizing a conceptual research model to investigate the relationships among the hypothesised factors. More specifically, classified as behavioural science, it combines two theoretical models, namely the Unified Theory of Acceptance and Use of Technology and the Expectancy Disconfirmation Theory. The main aim of behavioural science in information systems is to assist practitioners (Le., social actors) in improving business processes and competitiveness, thus the effective use of information systems. A wider view of behavioural science incorporates other social actors (e.g., end users) and organisational actors (e.g., executives). In health information systems, the effective use of information systems is especially relevant Health information systems are vital in the area of health care, since only by having access to pertinent health information, can the correct decisions relating to diagnostics and curative procedures be made. The use of systems development methodologies in health information systems development is therefore crucial, since they can make the development process more effective, while improving software quality. By empirically evaluating the conceptual research model, utilizing a survey as the main research method and structural equation modelling as the main statistical technique, meaningful results were obtained. Focussing on the factors influencing the individual's behavioural intent, it was found that the compatibility of systems development methodologies to the developer's pre-existing software development style is vital. Furthermore, performance expectancy, self-efficacy, organisational culture, policies, customer influence, voluntariness and facilitating conditions, all directly influenced the use of systems development methodologies, with policies and customer influence playing a significant role, especially in relation to health information systems. No significant direct effects or indirect effects could be established for the factors effort expectancy, personal innovativeness and social influence. It appears that individuals working in the health care software development discipline are more autonomous, less influenced by others. Also, the lack of support for the factor effort expectancy may indicate that systems development methodologies have entered a mature state, with less concern on the effort required for use. Furthermore, with regard to effectiveness and the continued use of information systems methodologies, satisfaction had a significant direct effect, with confirmation having a significant indirect effect.

There was a lack of knowledge about the user’s acceptance of smart devices as ubiquitous learning (u-learning) tools at higher education institutions in Sweden. As the mobile technology grows, the demand for mobile devices, particularly smart devices increases as well. With the increase in the usage of smart devices, the higher education institutions provide mobile learning platforms to attract more customers in the competitive industry of education. Thus, understanding the key factors from the perspectives of end-users is important for the institutions to survive in the competitive market. This study explores and explains Behavioral and Continuance intentions of students regarding the acceptance and usage of smart devices (Smartphones and Personal Digital Assistants or PDA) as u-learning tools. Key factors related to the users’ intentions to accept and continue using smart devices as u-learning tools were identified and hypothesized in the Swedish context. Ten hypotheses were suggested based on TAM, UTAUT, and ECT. To achieve the aim and objective of this study, a quantitative approach was chosen, and a survey strategy based on purposive and convenience sampling techniques were used. A web-based questionnaire on five-points Likert Scale was designed to collect the required data. 115 (96 valid) students answered the questionnaire. The collected data were used to conduct statistical operations in SPSS. Five hypotheses were supported, and the other five were not. The findings suggest that Performance Expectancy, Perceived Mobility value, Confirmation, and Satisfaction positively influence both Behavioral and Continuance Intentions of students to accept and continue using smart devices as u-learning tools. According to the findings, Confirmation and Satisfaction from ECT can be included as separate constructs in UTAUT and UTAUT2. Higher education institutions planning to have (and those that already have) learning platforms, compatible with smart devices, can benefit from the findings. Higher education institutions can also design their u-learning platforms according to the Performance Expectancy, Perceived Mobility value, Confirmation, and Satisfaction of the students. / Master program in Strategic-IT Management

Förväntad effekt av vårdens elektroniska IT-system är ökad patientsäkerhet, vårdkvalitet och tillgänglighet. Ett första villkor för att kunna uppnå detta är att IT-systemet används. I denna studie granskas ett underutnyttjat IT-system, använt för informationsöverföring mellan olika huvudmän vid samordnad vård- och omsorgsplanering. Granskningen baseras på teorier om hur individers intention och vilja till att använda ett IT-system initieras eller upprätthålls genom omgivningens påverkan. Resultatet visar att IT-användare i den patientnära vården (mikrosystemet) saknar adekvat tekniskt, organisatoriskt (mesosystemet) och ledningsstöd (makrosystemet), vilket kan förklara underutnyttjandet. / Expected impact of electronic healthcare systems is increasing patient safety, care quality and availability. Using the system is essential to achieve this. This study explain the assimilation gap in an electronic healthcare system used in coordinated care planning by theories how individuals’ intentions and willingness to use electronic systems is affected by environmental influences. The result shows that the end users lack technical, organizational, and management support, which can explains the assimilation gap.

Rapid technological progress has transformed our daily activities. One of these is how we pay for goods. Mobile payment is a payment option with great potential, but it is still struggling to become part of individuals' daily life. Previous research shows that adoption and acceptance of mobile payment vary widely between different countries. It is important to understand the determinants of mobile payment adoption, as cultural differences between countries may be one of the primary reasons for the different degrees of user mobile payment adoption. The purpose of this study is to investigate the factors, which influence user adoption of mobile payment in one Asian country, China, and one European country, Sweden. In addition, the aim of the study is to explore the difference in mobile payment adoption from the cultural point of view at an individual level. In this study, two research questions are proposed: what influences user intention to adopt mobile payment in the context of China and Sweden, and how does an individual culture influence user adoption of mobile payment in the context of China and Sweden. The research was conducted with a combination of an extended UTAUT (Unified Theory of Acceptance and Use of Technology) model with the added concept of Perceived Information security and Hofstede's cultural theory. Altogether, it was studied how these concepts influence Behavioural intention.  Based on the literature review of mobile payment adoption by users and Hofstede's culture theory, this study uses qualitative research to interpret the phenomenon on a deeper level with the intention of explaining it. Through observation, interviews, and questionnaires, several conclusions were drawn. The analysis of the results showed that the proposed research model applies to China and Sweden. Performance Expectancy, Effort Expectancy, and Social Influence have influenced the user mobile payment adoption in both studied countries, and Perceived Information Security has a strong influence on users in Sweden. The results also show that Power Distance, Collectivism, and Masculinity have a strong moderating effect on the behavioural intention of users in China, while Collectivism and Femininity have a strong moderating effect on the behavioural intention of users in Sweden. On this basis, it is suggested that cultural factors be incorporated into the research model of technology acceptance, and further research should be conducted in different countries to provide different perspectives.

Background: Emerging in December 2019, the COVID-19 pandemic profoundly changed consumer behaviour leading to social distancing and mitigating physical contact. Statistics show an increased use of contactless and mobile payment usage and adoption during the pandemic. It is unclear how valid previous models on mobile payment adoption explain adoption behaviour in emergency situations. While there are few studies approaching the adoption behaviour during the pandemic, there is also little previous research on mobile payment adoption prior to the pandemic in Germany. Purpose: The present thesis intends to advance several previously researched technological adoption frameworks to focus on and measure consumers’ perception of mobile payment technology adopting during the COVID-19 pandemic. Hence, our model provides a basis to understand mobile payment adoption in Germany during the pandemic. Method: Based on hypotheses derived from an adapted UTAUT2 model, we conducted quantitative deductive research reaching 258 questionnaire participants based in Germany. The empirical data was analysed through structural equation modelling. Conclusion: The findings show that Performance Expectancy still represents the primary driver of intention to adopt mobile payments during the pandemic, yet it is strongly supported by the initially contextualised Contamination Avoidance element and complemented by Habit, Effort Expectancy. Practitioners benefit from the study to better tailor campaigns in accordance with the main driver of adoption behaviour, while our findings contribute new insights into technology adoption in Germany during emergency situations.

Pregnancy is a sensitive period in women’s lives; pregnant women encounter various physical changes and emotional challenges during pregnancy. The vision for Sweden’s eHealth initiative is to be the best in the world in using eHealth to make it easier for people to achieve a healthy wellbeing and equal welfare by 2025. However, there is a lack of empirical studies in the area, especially studies associated with both eHealth and pregnancy in a Swedish context. Therefore, the thesis intended to seek the factors that affect a pregnant woman to adopt an eHealth innovation by applying qualitative interviews. Eleven women were selected including both women who are currently pregnant and women who have experienced pregnancy in recent years. Semi-structed interviews were chosen to gain more in-depth insights of the challenges during pregnancy. The data analysis followed the framework of Unified theory of acceptance and use of technology (UTAUT). Rogers’ innovation diffusion theory was discussed in relation to the study as well. The results based on the date from the study showed that the real drive for pregnant women to adopt an eHealth innovation is the dissatisfaction with the current solution, namely prenatal care in the Swedish public health care system. Other moderating factors that affect their intention for adoption are relevant knowledge, expertise support and trialability. The results revealed that women with foreign background were more likely to be dissatisfied with prenatal care in Sweden, and that professionals’ involvement in using the innovation and the possibility of experimenting with it will increase the intention of innovation adoption. Age, experience, and personality were not supported in having an impact on innovation adoption in this study. The limitations of the study are transferability and confirmability, where credibility, dependability and authenticity are high in this study.

Durante los últimos meses, el COVID-19 ha generado diversos cambios en el ámbito económico, social y personal de la sociedad. Tanto en el Perú como en todos los países del mundo se enfrentan a un entorno cambiante que los forza a adaptarse a los nuevos hábitos de vida y de consumo. De este modo, los rubros más importantes y básicos de la sociedad se vieron en la obligación de incurrir a nuevas formas de atención al consumidor, sin dejar la buena experiencia de consumo y de calidad de servicio para el usuario. El presente artículo destaca un enfoque en la intención de uso de plataformas eHealth, a partir del modelo UTAUT 2. Del mismo modo, nos basamos en la revisión de la literatura de los constructos incorporados en el modelo UTAUT 2 en un contexto pandémico que permitirá comprender los factores de la adaptación e intención de uso de las herramientas tecnológicas eHealth. / In recent months, COVID-19 has generated various changes in the economic, social and personal sphere of society. Both in Peru and in all the countries of the world they face a changing environment that forces them to adapt to new habits of life and consumption. In this way, the most important and basic areas of society were forced to incur new forms of customer service, without leaving a good consumer experience and quality of service for the user. This article highlights a focus on the intention to use eHealth platforms, based on the UTAUT 2 model. In the same way, we are based on the literature review of the constructs incorporated in the UTAUT 2 model in a pandemic context that will allow us to understand the factors of adaptation and intention to use eHealth technological tools. / Trabajo de investigación
