Bender - Geştalt Görsel Motor Koordinasyon Testi-II'nin (BGT-II) Global, Koppitz ve Geri Çağırma Puanlamaları İçin Yargıcılar Arası Güvenirliğin Değerlendirilmesi.

Objectives: In various studies which are made up to the present day, many neuropsychological tests is developed in order to determine structural and functional disorders in the brain. Bender Visual Motor Gestalt Coordination Test (BGT) is one of the most commonly used figure draw task that aimed to evaluate visual and perceptual skills. In that study it is aimed to establish inter-rater reliability of the Bender-Gestalt II, a new form of BGT, and to compare the new scoring system with the traditional Koppitz scoring system in terms of inter-rater reliability. Method: Sample is consisted of 22 male and 23 female child and adolescents. A newer form of the original Bender Visual Motor Gestalt Coordination Test (BGT), Gestalt Motor Coordination Test-II (BGT-II) is used in the study. Protocols are evaluated by three independent raters who are trained over Koppitz traditional scoring system and who have field experience. Results: For Global Scoring and Koppitz Scoring of BGT-II, internal consistency reliabilities of three raters over mean scores are calculated. It is found that internal consistency reliability for Global Scoring is, Cronbach alpha=.93, for Koppitz Scoring is, Cronbach alpha=.74. Results showed that two scoring systems have sufficiency (Cronbach alpha >.70) for clinic and research purposes. In addition, It is found that inter-rater aggrement for all scoring system is very high (for Koppitz ICC=.96; for Global ICC=.85 and for Recall ICC=.84). Conclusion: It is seen that three scoring system has sufficient internal consistency and inter-rater reliability values for clinical practice. [ABSTRACT FROM AUTHOR]
