Reliability and Validity of Scores on the Slosson Visual Perceptual Skill Screener.

Psychometric characteristics of the Slosson Visual Perceptual Skill Screener were studied using three independent samples of 595 boys and 578 girls ages 5 to 10 years. Adequate characteristics for item selection were indicated by item difficulty (Mdn = .49) and item discrimination (Mdn = .59). Inter...

Sumario:Psychometric characteristics of the Slosson Visual Perceptual Skill Screener were studied using three independent samples of 595 boys and 578 girls ages 5 to 10 years. Adequate characteristics for item selection were indicated by item difficulty (Mdn = .49) and item discrimination (Mdn = .59). Interitem consistency of .93 (n1 = 1,045) was recorded for the total scale, while 30-day test-retest reliability was .80 (n2 = 55). Convergent validity was estimated using the Bender Visual-Motor Gestalt test (Koppitz developmental scoring system; r = .43, n3 = 47), the Developmental Test of Visuo-motor Integration, Visual Perception subtest (r = .62, n3 = 73), and the Test of Visual Perceptual Skills-Revised-Nonmotor Total Score (r = .63, n2 = 59).
