| Background and Aim: In recent years, the use of mobile phone has increased prominently. The aim of the present study was to evaluate the psychometric properties of Mobile Phone Problem Usage Scale (MPPUS). Materials and Methods: The sample consisted of 200 students of Tehran University of Medical Sciences which were selected through convenience sampling. The participants responded to the MPPUS, the Addiction Potential Scale (APS) and the General Health Questionnare-28 (GHQ-28). Results: The validity of the questionnaire was investigated by convergent and discriminative validity and exploratory factor analysis. Results from factor analysis of the MPPUS using Varimax rotation method yielded in 4 factors which explained 57.26% of the total variance. MPPUS inter factor correlations ranged from 0.57 to 0.75 (p< 0.01). Convergent validity was assessed by computing a correlation coefficient between MPPUS, APS and GHQ-28 total scores, which was 0.47 and 0.45. Alpha Cronbach coefficient of internal consistency for total score of MPPUS was 0.90 and 0.95 using a spilt-half method. Conclusion: In general, findings of this research confirm the validity and reliability of the Persian version of MPPUS and show that this questionnaire can be used in Iranian samples for evaluation of phone problem usage. |
