Adaptive behavior refers to an individual’s ability to meet the paradigms of personal and social independence employed by the community in which they lives. It includes conceptual, social and practical skills. In different conditions from childhood to adulthood, they are associated with lossesin these domains. Due to the lack ofstandardized protocols for the intervention/stimulation of these skills for early childhood, the present study aimed to carry out the cross-cultural adaptation of the intervention plan of the Adaptive Behavior Assessment System (ABAS-3) for Parents/Caregivers of children between 0 and 5 years old (241 interventions divided into 10 subscales), as well as verifying the adequacy of the content of the intervention plan, based on the following steps: (1) translation of the intervention plan for parents/caregivers (0 to 5 years) by a translator; (2) Adequacy of semantic, idiomatic and conceptual equivalence by the researcher; (3) evaluation and synthesis of the adaptation by two experts, scored from 0 to 3 (0 = Totally disagree; 1 = Partially disagree; 2 = Partially agree and 3 = Totally agree); (4) Analysis of the adequacy of the synthesis by 33 judges from the areas of health and education (3 judges per subscale) and two parents/caregivers from the target population. Afterwards, the intervention plan was sent for evaluation of the suggested adjustments, and the two specialists from step 3 will forward the final version for approval by the authors of ABAS-3 and the publisher Hogrefe-Cetepp. The results point to good agreement between the judges and few adjustments made. Evidence of content adequacy was verified, considering the semantic, idiomatic and conceptual equivalences of the interventions, being considered an appropriate material for health professionals to use in guiding parents/caregivers on how to stimulate adaptive behavior in early childhood.
