Validation study of the Chilean version of the Dynamic Loewenstein Occupational Therapy Cognitive Assessment (DLOTCA)

Abstract

Objective: To validate the Chilean Spanish translation of the tenth English version of the Dynamic Loewestein Occupational Therapy Cognitive Assessment for use in the Chilean population. Method: The translation into Chilean Spanish was carried out, and then a pilot test was carried out for the application of the instrument, for which 40 adults were recruited with an average age of 42.7 years, with various brain damages and made up of 70% women and 30% men. To evaluate the reliability of the instrument, Cronbach's Alpha was calculated as a measure of Internal Consistency, applying 3 perspectives, "ItemTotal Reliability", "Item-Domain Reliability", and "Domain-Total Reliability". To measure feasibility, the percentage of items not answered by the sample is identified, and the percentage of items that is identified in the cognitive tests as understood. Results: The Item-Total reliability yielded a Cronbach's Alpha of 0.953, which translates into excellent reliability. Item-Domain reliability was mostly between excellent and good, with weak reliability for the factors "time orientation" and "visual perception". The Domain-Total reliability yielded a Cronbach's Alpha of 0.810, which translates into good reliability. Finally, in relation to feasibility, the participants answered 100% of the items, evidencing the translation to be accessible. Conclusion: The DLOTCA translated into Chilean Spanish; it presents a high reliability, which allows obtaining results with very low biases, becoming an instrument that can be used in a pertinent way in the Chilean population.
