Özet:

This study aims to develop a Social Network Self-Efficacy Scale for high school students.  The coverage validity, structure validity and item analysis processes were carried out for this purpose.  Research data was obtained from two separate groups of participants, who study at different levels, at different high schools in the Central Black Sea province of Turkey. Thus, the results obtained by the exploratory factor analysis during the scale development process were tested with confirmatory factor analysis on a different group. Within this scope, a total of 736 high school students participated in the survey, 253 in the first group and 483 in the second group. According to the results of exploratory and confirmatory factor analyses, a single factor structure consisting of 17 items was obtained. The Cronbach alpha internal consistency coefficients for the single factor final structure were calculated as .94 for the first participant group and .97 for the second participant group. This situation strongly points to the reliability of the medium. Again, the corrected item-total correlations remain above .49, which support the reliability results. As a result of the processes carried out for developing the Social Network Self-Efficacy Scale, it can be stated that the scale is a valid and reliable measuring tool.
