Sensory Profile Caregiver Questionnaire: a measure for sensory impairment among children with developmental disabilities in India.

Abstract

There is no validated measure for assessing sensory processing among children with Developmental Disorders (DD) in India, and therefore, the authors validated the Sensory Profile Caregiver Questionnaire (SPCQ). Parents of 119 children with DD or typical development completed the SPCQ. The diagnosis of DD was confirmed by psychologists using standardized measures. Two experienced occupational therapists independently diagnosed sensory processing dysfunction by consensus as reference standard diagnosis. The convergent and divergent validity were assessed by another rater. The data was analyzed for diagnostic accuracy, reliability and validity appropriately. A total SPCQ score of ≤ 481 (Sn = 81.58%, Sp = 85.19%; AUC = 0.90, z = 14.95; P 0.0001) is appropriate for the diagnosis of sensory processing dysfunction. The inter-rater reliability (ICC = 0.87), test- retest reliability (ICC = 0.90), internal consistency (Cronbach's α = 0.86), section-total correlation, face and content validity for the SPCQ were good. Convergent validity with the Sensory Processing Measure (r = -0.76, P 0.001), and divergent validity with the subscale scores for social skills/ oppositional behavior of ADD-H Comprehensive Teacher Rating Scale (r = 0.32; P 0.1/ r = 0.08; P 0.6) was established. The SPCQ has adequate psychometric properties for use in the Indian population for identifying sensory processing dysfunction.
