The sample included 25 articles. Results: All articles presented concepts related to MRT. Most developed a synthesis picture. Some theories have formulated specific propositions, hypotheses, and names. Only 16 articles cited the methodological framework, while 22 used theories or models for theoretical foundation and 11 carried out literature reviews.
