This study aims to develop a measurement tool that will allow a valid and reliable measurement of students’ acceptance levels within the framework of the Unified Theory of Acceptance and Use of Technology (UTAUT) model concerning LMS. The study was conducted in the 2016-2017 academic year with three groups of participants consisting of 515 medical students. Expert opinion was obtained to examine content validity and face validity of the scale, and exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to examine the construct validity of the conclusions based on measurements. A construct with four factors and 21 items was obtained at the end of the EFA, which explained 64.39% of the total variance. CFA results showed that the construct with four factors and 21 items had good fit to the data. The reliability of the measurements based on the scale was examined using Cronbach’s Alpha and test-retest methods. To examine the discriminatory power of the items, adjusted item-total correlations and a comparison of top and bottom 27% of participants were used. Findings of the study show that the scale can be used as a tool that generates valid and reliable measurements of students’ acceptance concerning LMS.

Background: Child obesity is one of the main health problems all across the world, which leads to mental and physical health problems. Various models are used in designing intervention to prevent child obesity, one of which is social-cognitive theory (SCT). The constructs of social-cognitive theory are commonly used for designing preventive interventions. However, there is no specific tool based on the constructs of social-cognitive theory to assess the factors associated with child obesity. Aim: The aim of this study was to investigate the validity and confirmatory factor analysis of a SCT-based questionnaire for assessing obesity preventing behaviors among 4-6 years old children. Method: A cross-sectional study was first conducted in 2016 on 240 preschool children aged 4-6 years in Behbahan city (a city in southwest Iran) to assess the obesity prevention behaviors among them using a SCT-based questionnaire. To investigate the validity and confirmatory factor analysis of the SCT-based questionnaire, content and face validity as well as forward-backward translation method were used. Reliability of the questionnaire was also measured by Cronbach’s alpha coefficient and Intra-class Correlation Coefficient (ICC). Construct validity was assured by confirmatory factor analysis. To measure the obesity prevention behaviors in 4-6 years old children, the construct of SCT, including environment, emotional coping, outcome expectations, goal setting and self-efficacy were used. Also, the obesity prevention behaviors used in the model included physical activity, consumption of fruit and vegetable, consumption of sugar-free drinks, and screen. Results: Results of this study confirmed the acceptable content and face validity of the SCT-based questionnaire. The results of confirmatory factor analysis also confirmed the factor loading of more than 0.3 for all variables; therefore, the SCT-based questionnaire had an acceptable validity and reliability. Conclusions: Since the SCT-based questionnaire had an acceptable validity and reliability, it can be used to assess the obesity prevention behaviors in 4-6 year old children, and also to design relevant educational interventions.

The aim of this study is to develop a measurement tool to measure the attitudes of pre-service teachers in science fields towards nanotechnology. For this purpose, a five-point Likert-type scale consisting of 55 items was applied to 373 pre-service teachers who are enrolled in science fields (Science, Chemistry, Biology, Physics) at the grades 1st, 2nd, 3rd, and 4th at a public university in Turkey. As a result of the exploratory factor analysis (EFA), it was determined that the scale had a 3-factor structure consisting of 24 items and the factors explained 55.854% of the total variance of the attitude variable. Verification of the model was tested by applying confirmatory factor analysis (CFA). The data used for CFA were obtained from 770 pre-service teachers who are enrolled in science fields at the grades 1st, 2nd, 3rd, and 4th at two different public universities in Turkey. The results obtained from CFA were in agreement with model obtained by EFA. Cronbach's alpha (Cr-α) reliability of the scale was calculated to be 0.926. Findings from the validity and reliability analyzes show that the scale is a valid and reliable measurement tool that can be used to measure pre-service science fields teachers’ attitudes toward nanotechnology.

Abstract Background Smartphone addiction is one of the most important forms of technology addiction that has attracted the attention of all countries around the world. Many studies have been conducted in Iran on cellphone addiction among different groups. There is a necessity to have a native scale for measuring smartphone addiction in particular. Therefore, this study aimed to localize the smartphone addiction questionnaire in Iran (in the Persian language). Methods To assess the validity and reliability of the Persian version of the smartphone addiction scale (SAS), the questionnaire was first provided based on the standard back-translation method. Next, content validity ratio (CVR), content validity index (CVI), and face validity was evaluated for translated questionnaire. After making the necessary changes, the questionnaire was given to the community samples and was then reviewed using confirmatory factor analysis of questions grouping. Finally, the reliability of the questionnaire was investigated by the test-retest method. Results The CVR and CVI values of all questions were within the acceptable range. Only some of the questions in the original SAS version titled Twitter and Facebook were changed to Instagram and telegram according to experts. Internal consistency and concurrent validity of the questionnaire were confirmed by Cronbach’s alpha of 0.951. The mean correlation coefficient between the responses of the subjects, who received the questionnaire twice, was 0.946 (0.938–0.954). The grouping of questions in the subscales was changed from the original SAS version because the fitting indexes, obtained from the confirmatory factor analysis test (for example CMIN/DF greater than 5 units and RMSEA of approximately 0.07), were not acceptable. Conclusion The results showed that the Iranian version of the cellphone addiction questionnaire can be used as a valid, with minimal modification, tool for determining the level of smartphone addiction among Persian speakers.
