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

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.
