 One of the major challenges in the implementation of the Picture Archiving And Communication System (PACS) is the attitudes of physicians towards the system. This study aims to design and assess the psychometric properties of a questionnaire for identifying the factors affecting the acceptance and use of PACS in Iran based on the Unified Theory of Acceptance and use of Technology (UTAUT).

 This methodological study with cross-sectional design was conducted with the participation of 400 physicians working in hospitals affiliated to Isfahan University of Medical Sciences in 2019. Physicians were selected by stratified random sampling method with the probability proportional to size procedure.  The questionnaire’s face validity, content validity, construct validity with exploratory factor analysis (EFA), test-retest reliability with intraclass correlation coefficient (ICC), and internal consistency with Cronbach’s alpha coefficient, were determined. The data were analyzed in SPSS.

 The face validity was 1.51-3.4 and the content validity index and content validity ratio ranged 0.6-1 in all factors. Twelve factors including performance expectancy, effort expectancy, social influence, facilitating conditions, computer self-efficiency, behavioral intention, technology optimism, problem solving, rationalized decision-making, horizontal integration, vertical integration, and presentation of health services to clients were extracted by conducting EFA, which explained 67.86% of the common variance. Cronbach’s alpha was obtained 0.92 and the ICC was 0.86 .

 The designed questionnaire has good validity and reliability. It is recommended as a valid tool to evaluate the factors affecting the acceptance and use of PACS in Iran.

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder in which individuals have difficulty in emotional processes related to social cognition and other behavioral patterns. The use of technology is increasing in therapeutic and educational interventions for people with ASD - who face ongoing challenges. Therefore, to select the interventions more appropriately and ensure their effectiveness, such interventions need to be evaluated. Thus, this study is an attempt to develop a framework for evaluating IT-based interventions among people with ASD.

The present study is a descriptive-applied study examining the information technology-based intervention studies in the field of ASD. The search and review of studies continued without any restrictions until an appropriate and complete framework of interventions was obtained. The required data were extracted and collected in a table focusing on the evaluation of ASD interventions. The data were then analyzed to determine an appropriate framework for the objectives of the study. Finally, the evaluation framework was prepared using the one-step Delphi method and sent to 15 experts in the field of autism and health information technology to obtain their views on changing, modifying, approving the framework.

In the framework developed in this study, two aspects of the interventions, including the type of information technology interventions and their outcome are generally presented. Moreover, the technologies used were presented from three main aspects: evaluation methods, technical evaluation cases, and clinical evaluation cases.

The results revealed that technology-based interventions can be of tremendous help in the treatment, education and increasing social interactions of people with ASD and thus bring about significant effects. Therefore, according to experts, the prepared assessment framework of interventions based on information technology leads to identifying the strengths and weaknesses of interventions, improving technologies as well as choosing appropriate interventions and ultimately increasing the quality of life of people with autism spectrum disorder.

According to economics classic assumptions, entrance of technology in health, can transit curve of a countrychr('39')s production facilities by reducing costs and increasing productivity, but from one time, development of technology which is used in the field of health, despite its increase share of health in GDP, will not have a significant effect on promoting social welfare and cheap and easy access to health services. So, the permanent question is where is the limit and border for technology entrance in the health sector for improving indicators? The answer of this question has made an issue named health technology assessment as a main point in health policy, which has an important role for promoting of countrychr('39')s health systemchr('39')s resilience and its level. Health technology assessment in Iran always related to policies of Ministry of Health and Medical Education. Evaluation the approach of countrychr('39')s health policy structure for technology issue needs to assess performance of this ministry.

This study performed by using scientific published references and semi-structured interviews.

Evaluation of health technology in Iran was performed in 5 areas including definition of technology, criteria for evaluating of technology, training of human resources, role of insurances in technology assessment and the role of new technologies.

Revising of the countrychr('39')s technology assessment model and decision-making structure regarding the entry of technology in the health sector is needed, especially considering the new types of technology in the health sector.
