ABSTRACT

The aim of this study is to develop a diagnostic scale to measure the influence of digital dependency, which has swiftly been a part of today's standards of living, on individuals in quite a tangible way and to carry out a validity-reliability study on this scale. The sample group of the scale consists of 450 university students (264 female and 286 male) studying at Cumhuriyet University in the 2017-2018 academic year. The scale has five-point Likert type and has been initially converted into a draft questionnaire consisting of 53 items. In accordance with the feedbacks from the field experts, some alterations have been employed, then it is made ready for pre-application. After the preliminary test, factor loadings below .30 are subtracted from the scale and structural validity has been ensured. The scale is concluded with 40 items possessing high internal consistency in the measurement tool. It has been determined that the KMO value of the scale is .94; Bartlett test .00 (p <.01); the released variance is 64.7% in the factor analysis of the scale. As a result of the confirmatory factor analysis, while the inter-item fit index is found to be significant in the Chi-square value (x2 = 756.20, N = 450, sd = 278, p = 0.00); it is detected that RMSEA: 0.075, SRMR: 0.14, GFI: 0.87, AGFI: 0.91, CFI: 0.98, IFI: 0.98, NFI: 0.093; x2/df = 2.78. The Cronbach's alpha (a) internal consistency coefficient of the scale is found to be .976. Considering the data obtained, with respect to its validity and reliability, it is assumed that the 40-item-scale for aged 19 or older will close the gap in the field and contribute to the literature.
