Purpose of the study is to realize the Turkish adaptation, validity and reliability study of Ostracism Experience Scale for Adolescents (OES-A), which was developed by Gilman, Carter-Sowell, DeWall, Adams, and Carboni (2013). The study was conducted with 461 adolescents aged between 14 and 17, in Istanbul. Exploratory and Confirmatory Factor analyses revealed that Turkish version of the scale has preserved the two factor construct of the original scale. OES-A consists of totally 11 items, distributed in two subscales. OES-A is a self-report, five point likert type instrument that measures two ostracism subtypes: Exclusion (6 items) and Ignorance (5 items). Factor loadings of the items are ranged from .83 to .59. All item-total correlations coefficients fell with the range of .75 and .83. Cronbach Alpha Coefficients were calculated as .82 for Ignorance Scale, and .83 for Exclusion Scale. Test re-test coefficients were found to be .65 for Ignorance Scale, and .63 for Exclusion Scale. In order to test the convergent validity of the instrument UCLA Loneliness Scale was administrated to another group of participants (n=343), correlations between two scales is calculated .55 for Ignorance Scale, and .45 for exclusion Scale.
