Cross-Cultural Adaptation and Reliability of the Toddler Sensory Profile 2 for Brazilian Children Aged 7 to 35 Months

Abstract

Aim To organize a cross-cultural adaptation study and analyze the reproducibility and test-retest reliability of a Brazilian version of the Toddler Sensory Profile 2 (TSP2Br) for children aged 7–35 months. Methods The English language version of the profile was translated and culturally adapted into Brazilian Portuguese, administered to 168 caregivers of toddlers aged 7–35 months, and then re-administered to a portion of the sample (39 caregivers; 23%) for 7–14 days for test-retest reliability. The internal consistency and test-retest reliability was analyzed using the Cronbach’s alpha and kappa coefficient, respectively. As it is a norm-referenced standardized assessment, the cut-off scores used were 1.0 and 2.0 standard deviations above and below the mean for each group of items established as the preliminary cut-off scores for the Brazilian children. Results The TSP2Br showed good internal consistency (>0.70) when measured on the total scale; however, when it was analyzed for sensory areas, five to seven areas presented alpha values <.70. By quadrants, alpha was <.70, for all items. The test-retest values fell into the category of near-perfect agreement (.89–.97). The preliminary cut-off points of the Brazilian scores were distinct from those of the Americans. Conclusions The TSP2Br showed preliminary reliability and validity in the identification of sensory processing problems in Brazilian children aged 7–35 months; however, it would be necessary to increase the sample size to generalize our findings to the general Brazilian population.
