The present study adapted the "questionnaire of Internet use motives" (MUI) into Turkish based on data collected from 638 adults. Results showed that the Turkish version of the MUI has a high internal consistency ([alpha]= 0.88) along with convergent and discriminant validity. The confirmatory factor analysis results supported the five-factor structure of the original MUI. Internet Addiction Test Short Form (IAT-SF) was used to test concurrent validity. The results indicated a significant positive correlation between the MUI and IAT-SF (r= 0.83), suggesting that individuals having higher levels of MUI may also tend to have higher levels of Internet addiction. The findings indicated that the adapted scale is a reliable and valid instrument to measure motives for Internet use in the Turkish population.
