Purpose:
This study aimed to cross culturally adapt the Protocol for the Exploration of Natural Metalinguistic Skills in Aphasia (MetAphAs), contributing to the future application in the aphasic Chilean population.
Method:
The sample corresponds to 72 healthy subjects in the region of Valparaíso, between the ages of 50 to 85. The MetAphAs measures natural metalinguistic skills and presents the basic elements on which to base the exploration of the metacognitive dimensions involved in verbal behavior. The validity was ascertained by means of Cronbach's Alpha Coefficient, including the values of each of the 6 sections; the correlations between variables were analyzed by the Pearson coefficient.
Results:
We observed that 64% of the sample corresponded to the female and 36% to the male gender, with predominant age ranging from 61 to 70 years. We verified adequate correlation between the variables according to the Pearson coefficient, and highly positive values according to Cronbach's Alpha.
Conclusion:
The use of the protocol is viable, with data demonstrating high reliability. The results evidenced high liability, which encourages the continuation process of its validation with Chilean aphasic population.
