Background: In Colombia there is little bibliography regarding the adaptation of instruments that assess the Activities of Daily Living in the population with neurodevelopmental disorders. On the other hand, existing research does not report processes of ecological validity or content adjusted to the Colombian contextual characteristics.
Objective: To carry out structural adaptations for the ecological and content validation of the questionnaire for the evaluation of activities of daily life – school or AVD-E, in the Colombian context.
Material and method: A divergent research methodology with a mixed approach and a DEXPLOS design was used, through three focus groups (10 professionals and 5 families), expert validation (8 professionals) and a pilot test (30 infants).
Results: In the qualitative stage, thirteen emerging categories were obtained that evidenced the need to make structural and linguistic changes. In the quantitative stage, content validity (RVC= 3.82), internal consistency (Cronbach’s Alpha= 0.76) and concurrent validity (Pearson= 0.58) were obtained.
Conclusions: In conclusion, the validated items make it possible to measure the variation of ADLs in the Colombian context, responding to the sociocultural particularities inherent to the ecological assessment of the construct.
