Abstract

Materials and Method: This is a cross-sectional and descriptive-analytical research. For these purpose 400 students of Isfahan universities were subjected. Sampling method was quota sampling. Cases completed demographic questionnaire, Compulsive Internet Use Scale (CIUS) and YDQ (Young Diagnostic Questionnaire). Finally we performed a psychiatric interview (based on DSM-IV-TR) for all of the samples. For data analysis we used face, discriminative and concurrent validity, Chronbach α, split half, test-retest and ROC Curve by SPSS-14 Software.

Results: Concurrent validity was (r=0.78, 0.81), discriminative validity was (r=0.62). Besides YDQ shows internal consistency (α=0.70), split-half validity(r=0.64), test –retest reliability (r=0.74, p<0.01). The best cut off point for this questionnaire is number 4.

Conclusion: The result showed that Persian version of YDQ is valid and reliable. Considering lack of a valid and reliable questionnaire for measuring addiction to the internet, YDQ could be a suitable tool for measuring internet addiction in future research
