This study aimed to adapt the Selfitis Behavior Scale (SBS) to measure university students' selfitis behavior in Turkey. Within the scope of the study, the SBS was translated from English to Turkish. Data were collected in the validity and reliability studies from four study groups, including 343 university students. According to the confirmatory factor analysis findings, the SBS had good fit indices. As is expected, the criterion-related validity study found moderate- and high-level positive correlations between the SBS subscales and total scores and the Selfie Attitude Scale (SAS) subscales and total scores. The other criterion-related validity study demonstrated that individuals taking a higher number of selfies than the sum of the scale and subscales scored significantly higher than individuals taking a lower number of selfies. The internal consistency coefficient was calculated to be 0.92 for the SBS total score, 0.78 for the Environmental Enhancement Subscale (SBS-EE), 0.68 for the Social Competition Subscale (SBS-SC), 0.72 for the Attention-Seeking Subscale (SBS-AS), 0.84 for the Mood Modification Subscale (SBS-MM), 0.82 for the Self-Confidence Subscale (SBS-S), and 0.70 for the Subjective Conformity Subscale (SBS-SCon). The test-retest correlation values found by applying the measurement tool once in four weeks were 0.77 (SBS), 0.70 (SBS-EE), 0.60 (SBS-SC), 0.82 (SBS-AS), 0.80 (SBS-MM), 0.61 (SBS-S), and 0.61 (SBSSCon), respectively. The mentioned findings demonstrated that the SBS was a valid and reliable measurement tool capable of measuring the selfitis behavior of university students in Turkey.
