The validity and reliability of Persian version of smartphone addiction questionnaire in Iran

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.

Abstract Background Old age is associated with reduced physical ability. It is necessary to measure and evaluate the physical activity of older people. Implementing appropriate requires a valid and reliable tool. Physical Activity Scale for the Elderly (PASE) is the frequently used self-reported physical activity assessment for older adults. Therefore, this study aimed to determine the translation validity and reliability of the Persian version of the Physical Activity Scale for the Elderly. Methods This study is a methodological, descriptive applied research was conducted on 300 older people. The translation process of the English version of PASE into Persian was carried out according to the process of translation and adaptation of scale recommended by the World Health Organization. The reliability of the scale was examined by calculating the Cronbach’s alpha, Pearson, and intraclass correlation coefficient (ICC). The reliability and validity of the scale were evaluated by following the “Consensus-Based Standards for the Selection of Health Status Measurement Instruments” (COSMIN) checklist. To assess the face and content validity, impact score (IS), the content validity ratio (CVR), and the content validity index (CVI) were determined. A confirmatory factor analysis was also performed. Results The experts approved the quality of the Persian version of PASE. The reliability was calculated with a Cronbach’s alpha of 0.94, an ICC of 0.99, and a test-retest correlation coefficient of 0.94. The qualitative and quantitative face validity of all questions by expert judgment and IS of greater than 1.5 was considered. Also, CVR and CVI scores of all questions were higher than 0.6 and 0.79, respectively. Confirmatory factor analysis revealed a good fit for the original three-factor structure. Conclusions The Persian or Farsi version of PASE was shown to have acceptable validity and reliability. This tool is suitable for measuring the physical activity level in the Persian elderly language special in clinical environments and therapeutic interventions.

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.

Background: Sensory integration is a necessary skill for acquiring reading skills because it strongly depends on the rapid and strong relation between written and verbal symbols. There is no standardized test for Iranian children with dyslexia to investigate their sensory processing problems. Therefore, understanding the validity and reliability of the child sensory profile 2 (CSP2) would be essential for a detailed assessment of sensory impairments in dyslexic children. Objectives: The current research aimed to establish the internal consistency, factor analysis, and convergent validity of the Persian version of CSP2 in children with dyslexia. Methods: The sample of this study included 200 dyslexic children aged 6 to 12 years who were referred to learning disabilities centers in Qom from September 2019 to February 2020 by using the multistage sampling method. To collect data, the CSP2 questionnaire and the dyslexia test (NEMA) were used. The factor structure was assessed by confirmatory factor analysis. The internal consistency of the CSP2 was examined by using Cronbach’s alpha. Convergent validity was assessed by examining the relationship between CSP2 and NEMA. Results: Internal consistency was obtained as 0.89, 0.92, 0.77, and 0.94 for the four subscales of sensory processing, namely registration, seeking, sensitivity, and avoiding, respectively. The result of confirmatory factor analysis gained support for Dunn's four-factor model. Total scores of NEMA were correlated with the scores of CSP2 subscales (seeking, avoiding, sensitivity, and registration). Conclusions: The Persian version of the Child Sensory Profile 2 is a valid (via confirmatory factor analysis and convergent validity) and reliable (via internal consistency) tool for assessing sensory processing in children with dyslexia.

Abstract Background: Sexual health is a human right, yet there is a lack of comprehensive, standardized and culturally appropriate instruments to assess sexual health in Iran.Objectives: This study aimed to assess the psychometric properties of the Persian version of the Sexual and Reproductive Health Illustrative Questionnaire (SRH-IQ).Material and methods: This was a methodological psychometric study conducted in Tehran, Iran, during 2014–2015, with a sample of 755 men and women aged 15–49 years. The SRH-IQ was translated and adapted via the method recommended by the world health organization.. Qualitative and quantitative face and content validity were evaluated and the construct validity assessed using exploratory and confirmatory factor analysis. The internal consistency and the stability of the tool were assessed using Cronbach’s alpha, Intraclass Correlations Coefficient (ICC) and test–retest method.Results: Several items were changed in accordance with the cultural and religious beliefs of Iranians. The mean item-level content validity index (I-CVI) was 0.98; the content validity ratio (CVR) was high at 0.976; and scale-level content validity average (S-CVI/Ave) and scale level content validity universal agreement (S-CVI/UA) were found to be 0.97 and 0.94, respectively. Exploratory and Confirmatory factor analysis confirmed that all items in domains were significant, and the results supported goodness of fit indices, too. The final Cronbach’s alpha coefficients of all sub-scales were > 0.60 indicating acceptable internal consistency. Test-Retest data analysis showed that the ICC was higher than 0.88 for most items (0.75–0.99). Kappa coefficients were above 0.8 in most instances (0.65–0.99).Conclusion: Given the appropriate validity and reliability of the Persian version of the SRH Questionnaire, it can be used to assess sexual health knowledge, attitudes, behaviour and outcomes of Iranian adults.Plain English Summary Sexual health is an integral component of human right, and it is an important basis for an individual’s physical and psychological well-being, as well as the social and economic development of communities. Evaluating the sexual health needs of people is necessary to address sexual health goals. Several studies have been conducted within the field of sexual health in Iran, however, no Persian instrument is available to assess the sexual health needs of adults within the reproductive ages. In order to make it applicable within the context of Iranian culture, we have investigated the psychometric properties of the Persian version of the Sexual and Reproductive Health Illustrative Questionnaire (SRH-IQ) among Iranian men and women in reproductive age. With this aim, we have recruited 755 men and women aged between 15-49 years in urban Tehran, Iran. Several items of the questionnaire were changed in accordance with the cultural and religious beliefs of Iranians. Exploratory and Confirmatory factor analysis confirmed that all items in domains were significant, and the results supported goodness of fit indices, too. All in all, this study has given the appropriate validity and reliability of the Persian version of the SRH Questionnaire, and it can be used to assess sexual health knowledge, attitudes, behaviour and outcomes of Iranian adults.

Maslow’S Hierarchy Of Needs

The present study aimed to adapt and validate the Maslow’s Hierarchy of Needs in the EFL settings of Iranian universities. A review of the related literature showed that there are very few studies on the application of Maslow’s hierarchy of needs in learning contexts, especially that of foreign/second language classes. To do so, having revised and rephrased the items in the scale developed for Hierarchy of Needs, the researcher made sure of the content validity and reliability of the revised version. Afterwards, the designed questionnaires were distributed among 271 learners of language studying at Ferdowsi, Imam Reza and Tabaran universities. The obtained data were then analyzed. Confirmatory factor analysis procedures were held to ensure the construct validity of the questionnaire. The designed scale was validated through certain statistical procedures. Confirmatory Factor Analysis and content validity procedures were done to ensure the validity of the scale. In addition to this, using Coranbach’s coefficient of reliability, the items and the scale as a whole were proven to be reliable. The significance of the work lies in the fact that the better an educator knows their own students, the better rapport they can establish with them. This can to a great extent improve the teaching and learning process in different contexts. It is to be said that this scale can be of great significance in any kinds of research in the field that deals with needs and expectations of students at different levels.
