        This study aimed to determine the psychometric properties of the Smartphone Addiction Scale (SAS) in a sample of 208 Iranians. The convenience sampling method was employed to select individuals with smartphones living in Tehran. The participants completed the SAS and Young’s Internet Addiction Test (IAT). Construct validity and convergence validity were employed to analyze the scale validity, whereas the retest method and Cronbach’s alpha were adopted to evaluate its reliability. According to the confirmatory factor analysis results of evaluating the construct validity and the SAS structure, the research data are consistent with the model. In other words, the fitting indices were within an appropriate range, and the SAS had a factor structure with six subscales. Therefore, the construct validity of the SAS was confirmed. Moreover, its convergence validity was confirmed with Young’s IAT (r= 0.75). The retest correlation coefficient (r= 0.93) and Cronbach’s alpha for internal consistency (α= 0.92) confirmed the reliability of the scale. Therefore, the 33-item SAS had acceptable psychometric properties in six scales. It can be used as a valid and reliable tool to analyze an Iranian population. Manuscript Document

        The aim of this study was to investigate the validity, reliability and factor structure of the Female Sexual Well-Being Scale in Iranian married women. For this purpose, a sample of 297 married women (with a mean age of 33.7 years and an age range of 24 to 45 years) was selected by simple random sampling. The Psychological Well-Being Questionnaire (Reef, 1995) and Women's Sexual Well-Being Scale (Rosen et al., 2009) were completed by the sample group. The validity of this scale was assessed using exploratory and confirmatory factor analysis methods, convergent and simultaneous validity. The reliability of the scale was evaluated by two methods of Cronbach's alpha and halving. The results of factor analysis using principal component method and varimax rotation showed that this scale consists of 4 factors with the titles of interpersonal relationships, cognitive-emotional domain, physical stimulation and orgasm satisfaction, which is more than 66% of the variance. They explain the whole. The convergent validity of this scale indicated a satisfactory correlation between the dimensions of the female sexual well-being scale and the total score. To determine the simultaneous validity of the scale, the correlation between the dimensions of the female sexual well-being scale and the psychological well-being scale was used, which indicated a favorable correlation (p <0.001). Cronbach's alpha and halving coefficients for the whole scale and its dimensions ranged from 0.63 to 0.82. The final result is that the Persian form of the Women's Sexual Welfare Scale has good validity and reliability in Iranian society and can be used in research, educational and clinical situations.
