Psychometric Properties of the Persian Version of Nomophobia Questionnaire

Abstract

Objectives: This study aims to assess the validity and reliability of the Persian version of Nomophobia Questionnaire (NMP-Q) for use on Iranian population. Methods: This is a correlational study. Participants were 280 undergraduate students in Mashhad, Iran in 2017 who were selected by multistage cluster sampling method. They completed the Persian version of NMP-Q and the Cellphone Overuse Scale (COS). To assess the test-retest reliability, 40 participants completed the questionnaire again two weeks later. Collected data were analyzed in SPSS v. 20 and LISREL v. 8 applications using Cronbach’s alpha, Pearson correlation test, and confirmatory factor analysis. Results: The results showed the high internal consistency of the questionnaire (α= 0.921 for overall scale and 0.748-0.885 for subscales). Correlation coefficients for assessing concurrent validity and test-retest reliability were reported 0.51 and 0.81, respectively. According to the results of confirmatory factor analysis, all four subscales of the main version were confirmed in the Persian version. Conclusion: The Persian version of NMP-Q has good validity and reliability for use in Iran.
