        The present study aimed at investigating the mediating role of mindfulness in the relationship between depression, anxiety, stress and psychological well-being. Current study is a descriptive study. A total of 198 (137 female and 61 male) participants completed the paper-and-pencil form of Depression, Anxiety, and Stress Scale (DASS), Mindfulness Attention Awareness Scale (MAAS) and Ryff Psychological Well-being Scale. The mediating role of mindfulness was explored using the PROCESS v3.0 plugin for SPSS. The results revealed that mindfulness significantly (p<0.01) mediated the relationship between 1) anxiety and total well-being, 2) anxiety and mastery as well as depression and master, and 3) all three independent variables and self-growth. Data also showed that, regarding some emotional disturbances (i.e., anxiety), trait mindfulness could prove similarly effective with both low and high emotionality, while with respect to other difficulties (i.e., depression) it will only foster psychological well-being when negative affectivity level is only low or moderate.

        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
