Abstract:

Objective: Specialists often assess the motor proficiency of children presented with suspected developmental delays. It is essential that the tools used to assess children have highly powerful measurement properties including psychometric properties. The aim of our study, analyze the reliability and construct validity of the Turkish version of the Bruininks Oseretsky Test of Motor Proficiency 2-Brief Form (BOT2-BF) in children with a specific learning disability (SLD). Methods: Participants, which aged between 6 and 14, were included 137 children with SLD and 50 children without any diagnosis. The Turkish version of the BOT2-BF was administered by the researcher in one session to children with SLD twice with a seven days interval. In addition, BOT2-BF was re-apply to 25 children with SLD, which were randomly selected, after 10 days. Results: The validity results of BOT2-BF were found to be significantly better in all subtests in the control group than in the study group, having higher performance levels (p<0.05). The BOT2-BF demonstrated high test-retest reliability (ICC >0.8) (except Fine Motor Precision (ICC=0.57) and Manual Dexterity Subtest (ICC=0.74) and good internal consistency (Cronbach’s alpha =0.78) for all domains. The inter-rater reliability results were found to be perfectly reliable (ICC >0.9). Conclusion: The Turkish version of BOT2-BF was found to be a valid and reliable assessment to evaluate motor proficiency in children with SLD.
