Abstract

Context: The King-Devick (KD) is a gross screening tool designed to assess for cognitive visual impairments, namely saccadic rhythm, post-concussion. Test-retest reliability of the KD in a healthy adolescent population has not yet been established. Objective: Within a sample of healthy adolescents: (1) examine test-retest reliability of the KD; (2) investigate effect of gender on test-retest reliability of the KD; and (3) investigate effect of age on test-retest reliability of the KD. Design: Repeated Measures Design. Setting: Secondary School. Participants: Sixty-eight healthy children with no reported learning disabilities including 41 boys (age=15.4±1.9yr, ht=168.8±39.8cm, wt=71.2±30.8kg) and 27 girls (age=15.4±1.9yr, ht=154.4±45.4cm, wt=57.0±28.8kg). Interventions: Participants completed the KD/Version A at each of three testing sessions (Day 1, 30 days, and 45 days). Main Outcome Measures: Total time a child required to complete reading three cards as well as errors committed while reading were recorded for each child during each testing session. Repeatability coefficients (CR) were calculated and linear mixed models were used to determine changes in testing times as well as age and gender differences over the 3 visits. Results: The KD demonstrated poor repeatability (CR=± 8.76 seconds) among all participants. The entire sample demonstrated significant improvements between visits 1 and 2 (4.3±0.5 seconds, mean ± SE, p
