The Adaptation of the Social Media Disorder Scale to Turkish Culture: Validity and Reliability Study

The present study aimed to test the reliability and validity of Social Media Disorder (SMD-9) Scale in Turkish adolescents and to examine its psychometric properties. Three study groups were conducted among a total of 586 (202+204+180) Turkish adolescents aged from 13 to 18. According to explanatory factor analysis results, it was found that the Turkish form of the SMDS had one-dimension just like the original version and the unidimensional scale explained 48.11% of variance related to the attribute it measured. In confirmatory factor analysis, fit index values were found as χ2/df=1.87, RMSEA=.066, CFI=.98, GFI=.98, IFI=.98, NFI=.96, RFI=.97, and SRMR=.039. Factor loadings ranged from .35 to .76. In the concurrent validity, the Social Media Disorder Scale had significant relationships with Young’s Internet Addiction Test-Short Form and Smart Phone Addiction Scale-Short Form for Adolescent (r= .64, .66, respectively). Cronbach alpha internal consistency coefficient was found as .75. Guttman split-half reliability coefficient was found as .64. Corrected item-total correlations ranged from .29 to .73. Overall results demonstrated that Social Media Disorder Scale can be used for Turkish adolescents as a valid and reliable instrument
