title: Reliability and validity of scores on the Slosson Visual Perceptual Skill Screener.
abstract: 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).
