[The reliability and validity of the Buss-Perry Aggression Questionnaire (BAQ)-Turkish Version].

OBJECTIVE The aim of the present study was to develop, and assess the validity and reliability of the Buss-Perry Aggression Questionnaire (BAQ)-Turkish Version. METHODS The BAQ was translated from English to Turkish by a bilingual individual, and then independently translated back to English by another bilingual individual. The study included 220 students from 2 universities. In order to determine the criterion validity of the BAQ-Turkish Version, its correlation with the Multidimensional Anger Scale anger-related behaviors subscale (Balkaya and Şahin 2003) was determined. To determine the test-retest reliability of the BAQ-Turkish Version the scale was administered twice (with a 4-week interval) to 53 of the participants. To determine the scale's reliability internal consistency (Cronbach's alpha), test-retest, and split-half methods were used. The scale's criterion validity and gender differences were examined. RESULTS The scale was observed to have high internal consistency and appropriate stability over a 4-week period. Only 1 significant gender difference was observed--males had significantly higher physical aggression scores than females. All BAQ-Turkish Version subscales were strongly inter-correlated. CONCLUSIONS The findings support the 4-factor structure of the BAQ-Turkish Version, as originally reported (Buss and Perry 1992), and show that the BAQ-Turkish Version is a reliable and valid instrument for measuring aggression in the Turkish population.
