This study investigated the validity and reliability of the Turkish version of the Berkeley Expressivity Questionnaire (BEQ; Gross & John, 1995). The sample of study consists of 425 university students. Results of language equivalency showed that the correlations between Turkish and English forms ranged from .62 to .83. Results of exploratory factor analysis showed that the 16 items loaded on three factors (positive expressivity, negative expressivity, and impulse strength). The total variance explained was 58% and factor loadings ranged from .53 to .90. Fit index values of the model were RMSEA=.048, NFI=.96, CFI=.98, IFI=.98, RFI=.95, GFI=.95, AGFI=.92, and SRMR=.048. Internal consistency reliability coefficients varied between .74 and .88 and test-retest reliability coefficients varied between .66 and .85. These results demonstrate that this scale is a valid and reliable instrument
