This study assesses the validity and the reliability of using the Sensory Balance Test as screening for possible sensory integration deficits. Twenty typically developing children and twenty children with sensory integration deficits were recruited. All participants took the Sensory Balance Test which evaluates children's balance ability under six different sensory conditions. The primary analysis result shows that the sensory balance composite score is associated with children's current sensory integration functioning status (adjusted OR = .97, 95% CI = .95, .99, p = .004). Secondary analyses demonstrate an excellent agreement (Kappa = .80) between children's current sensory integration functioning status and their predicted status and an excellent test-retest reliability on summary scores for both typically developing children and children with sensory integration deficits (ICC = .92 and .88 respectively). The findings indicate that there is a significant difference between typically developing children and children with SID on the sensory balance composite score (mean difference = 149.10, p = .01). The results also show that there is a significant difference on the weight shifting score for conditions 4, 5, and 6 between typically developing children and children with SID, however, those scores do not differ significantly on conditions 1 to 3 between the two groups. Findings from this study suggest that the Sensory Balance Test provides a valid and reliable tool to screen children with possible sensory integration deficits in an objective, efficient, and effective manner.
