BACKGROUND: Monitoring child development requires not only the determination of developmental milestones but also surveillance and continuous monitoring, hence the importance of having valid and reliable evaluation instruments. This research aimed to cross-culturally adapt the Child Development Evaluation (CDE) test for Colombia and determine its validity and reliability. METHODS: The cross-cultural adaptation process was conducted in four phases: I. Adaptation to Colombian Spanish: adjustments of the test to Colombian Spanish and analysis of equivalences
II. Content and face validity: evaluation by five expert judges who performed quantitative and qualitative assessments of the test
III. Review by the original author
IV. Pilot test. Reliability analyses for internal consistency and intra-rater reliability were performed. RESULTS: For the adaptation to Colombian Spanish, most test items were equivalent to Mexican Spanish, with some requiring minimal conceptual and contextual changes to maintain their meaning
culturally relevant formulations and expressions were adjusted. In the content and face validity assessment, adequate results were found regarding the importance, influence, and observability of the items. Internal consistency reliability was moderate, with Cronbach's α values between 0.41 and 0.57, and intra-rater reliability was very good, with Kappa index values >
0.76. CONCLUSION: The CDE test demonstrates cross-cultural adaptation, content and face validity, and reliability for its application and use in Colombia.
