Developmental Motor Scale: Adaptation for Children with Low Vision from 7 to 10 Years Old

ABSTRACT

Low vision is a type of visual impairment that can influence the child’s functionality and cause important changes in the acquisition of motor skills during childhood. The objective of this paper was to evaluate the reliability aspects in the adaptation of the Developmental Motor Scale (PDMS) for children with low vision, from 7 to 10 years of age. Twenty-two children with low vision (± 9.12 years) participated in the study. The scale was adapted in four stages. To analyze the agreement between the judges’ answers, the agreement index (≥ 80%) was used, and for the reliability of the adaptations the inter-rater and retest analysis was used (Intraclass Correlation Coefficient). The results showed that the agreement rate between the judges was ≥80% in the second round of adaptations, which showed excellent reliability in the inter-rater analysis (ICC≥1,000) and in the retest test (ICC≥0,990) for the motor age, and excellent inter-rater reliability (ICC≥1,000) and in the retest test (ICC≥0.997) for the motor quotient. The PDMS was adapted and presented good methodological reliability. Thus, its adaptation will allow the correct use of the instrument in children with low vision, determining the most accurate functional/motor diagnosis of motor alterations in this population.
