Abstract

Investigations exploring the purported reciprocities between psychomotor and cognitive skills are mounting. However, such inquiries are limited in adolescents with visual impairment (AVI). This disparity is (in part) due to the fact that psychometrically-vetted cognitive and executive function test scores/studies derived from AVI are scant. While large sample investigations are needed, pilot psychometric studies are an advisable antecedent. The purpose of this study was to investigate preliminary convergent and known-groups validity evidence for scores from various executive function tasks in AVI. Thirty-seven participants (Mage=13.59 ± 2.80 years) completed a background information questionnaire, several anthropometric measurements, as well as the Head-Toes-Knees-Shoulders measure (i.e., total and efficiency score), Wechsler forward and backward digit spans (i.e., total correct spans), and the ‘walk a line slowly’ task (i.e., difference between instructed ‘typical’ and ‘slowest’ trials). Convergent validity was examined via Spearman correlations. Know-groups validity was assessed using robust regression. Forward and backward digit span scores correlated (rho=.44, p=.006) as did both Head-Toes-Knees-Shoulders scores (rho=-.81, p< .001). The backward digit span correlated with both Head-Toes-Knees-Shoulders scores (rho=.35, p=.032; rho=-.44, p=.007). Having a cognitive disability was predictive of impaired performance across the digit span and Head-Toes-Knees-Shoulders scores (adjusted R2 range=.10 to .28; p< .05 to < .001). Being a girl was predictive of improved Head-Toes-Knees-Shoulders scores yet impaired ‘walk a line slowly’ performance (adjusted R2 range=.07 to .11; p< .05). Age nor vision level were predictors of any executive function scores (p>.05). Validity evidence of scores for the Head-Toes-Knees-Shoulders and the backward digit span were strongest in AVI.

Preliminary convergent and known-groups validity evidence for scores from various executive function tasks in US adolescents with visual impairment

Investigations exploring the purported reciprocities between psychomotor and cognitive skills are mounting. However, such inquiries are limited in adolescents with visual impairment (AVI). This disparity is (in part) due to the fact that psychometrically-vetted cognitive and executive function test scores/studies derived from AVI are scant.
