Background: The Metacognitive Awareness Inventory (MAI) is used all over the world to identify metacognitive components that are relevant to learning. However, there is not enough evidence confirming its factorial structure or the suitability of its Shortened Version, proposed by various authors. Also, to date, the MAI has not been validated in the Spanish context.
Method: After adapting the MAI to Spanish, it was administered to 1076 university students from different regions of Spain. Different structures of the MAI Shortened Version, with 19 items, were compared with the structures of the original 52-item MAI. Indexes of validity and reliability were analyzed, considering the factorial structure and relationships to other validated questionnaires.
Results: Only the MAI Shortened Version that differentiates between knowledge and regulation of cognition achieved a good fit. These two scales showed good convergent and divergent validity, high criterion validity in relation to academic achievement, high test- retest reliability, and high internal reliability.
Conclusions: results support the traditional differentiation between knowledge of cognition and regulation of cognition, but only for the Shortened Version of the MAI. This instrument allows quick evaluations and identification of these components in Spanish contexts with adequate metric properties.
