This study aims to establish a Turkish version of the Children’s Inventory of Anger Scale (ChIA) developed by Nelson and Finch (2000) to evaluate the intensity of anger experienced in potentially anger-provoking situations in children. The research sample consists of 502 primary and secondary school students attending their education in Hatay province of Turkiye. In the study, the construct validity of the ChIA, correlations of subscales with each other, criterion relative validity, Cronbach’s alpha internal consistency, item-total score correlation, and test-retest reliability coefficients were examined. As a result of the confirmatory factor analysis performed for the construct validity of the scale, it was observed that the ChIA was compatible in four sub-dimensions as in the original scale and all items were placed in the relevant sub-scale. In addition, Cronbach’s alpha coefficient of the ChIA was found to be .87, .78, .82, .75, and .81 for the sub-scales of inhibition, physical aggression, peer relations, and authority relations, respectively; test-retest consistency was found to be .83, .80, .82, .87 and .81 for inhibition, physical aggression, peer relations, and authority subscales, respectively. Statistical analyses of the ChIA have shown that it is a valid and reliable scale that can be used to measure the expression of anger and the impact of anger on personal relationships while assessing specific situations that cause anger in children aged 8-11 years.
