The initial psychometric properties for the Total Body Developmental Sequences for youth with visual impairments

摘要

Youth with visual impairments often show difficulties with gross motor skills regardless of age or sex. Gross motor skills support positive developmental trajectories for health warranting the need for assessment. The Total Body Developmental Sequences (TBDS) are fast, easy-to-use, indices of gross motor development with relatively unknown psychometric properties for youth with visual impairments. The primary purpose of this study was to assess the psychometric properties of the TBDS with a secondary purpose to evaluate differential effects of biological sex, age, and degree of vision on gross motor skills. Youth with visual impairments (N = 57, ages 9 - 19 years, Boys = 23, Girls = 34) completed the TBDS and the Test of Gross Motor Development (TGMD-3). Results showed good initial psychometric properties (r = .89, alpha = .84,p .05). The TBDS may now be used as an initial gross motor screening tool for youth with visual impairments. This initial screen (TBDS) is warranted as youth with visual impairments may show arrested development which may be exacerbated with more severe visual impairments.
