This study examines the psychometric properties of the Test of Gross Motor Development-2 (TGMD-2) in children with visual impairments (VI). Seventy-five children aged between 6 and 12 years with VI completed the TGMD-2 and the Movement Assessment Battery for Children (Movement ABC). The internal consistency of the TGMD-2 was found to be high (alpha = 0.71−0.72) and the interrater, intrarater, and test-retest reliability acceptable (ICCs ranging from 0.82 to 0.95). The results of the factor analysis supported internal test structure and significant age and sex effects were observed. Finally, the scores on the object control subtest of the TGMD-2 and the ball skills subtest of the Movement ABC correlated moderately to high (r = 0.45 to r = 0.80). Based on the current results, it is concluded that the TGMD-2 is an appropriate tool to assess the gross motor skills of primary-school-age children with VI.

Reflection is considered a key factor in expert learning and refers to the extent to which individuals are able to appraise what they have learned and to integrate these experiences into future actions, thereby maximizing performance improvements. We assessed the relation between self-reported reflection at baseline and attainment (i.e., international vs. national level) 2.5 years later in 52 elite youth athletes. A Mann-Whitney U test showed that those who became senior internationals scored highest on reflection during their junior years compared with those who only attained senior national status. More specifically, athletes who made the transition from junior national to senior international level had higher reflection scores than their peers who did not reach international status and had similar scores to those who were internationals as juniors. These results emphasize the value of reflection in elite youth athletes to attaining senior international status later in development.
