The aim of this study was to develop the Reasons for Instagram Use Scale and to investigate whether instagram motives are changed according to gender and type of school. The study was conducted with 878 students in two secondary schools and two high schools in Istanbul. Of the participants, 336 (38.3%) were male and 542 (61.7%) were female. Exploratory factor analysis was conducted with 442 students and confirmatory factor analysis was conducted with 436 students. Reasons for Instagram Use Scale and Social Media Addiction Scale were used in the study. Expert opinion was sought for content validity. As a result of factor analysis, it was seen that 15 items were grouped under four factors with eigenvalues greater than 1. The first factor was determined as popularity and prestige, the second factor was amusement, the third factor was following others, and the fourth factor was escaping problems. It was seen that the factor load values of the scale items ranged between .65 and .85, and item total correlations ranged between .28 and .51. The scale items were found to have a good level of discrimination. The fit indices obtained from the confirmatory analysis were found to be acceptable (X2 / sd = 3.40, RMSEA = 0.07, SRMR = 0.05, IFI = 0.90, CFI = 0.90, GFI = 0.92, AGFI = 0.89). Cronbach Alpha internal consistency coefficient was .82. As a result, the scale was found to be a valid and reliable scale to measure the motives of instagram use in adolescents.
