Executive functions beyond the "Holy Trinity": A scoping review.

OBJECTIVE

Executive functions (EFs) are a multifaceted construct, important for several outcomes throughout life. The most commonly addressed executive components are inhibitory control, working memory, and cognitive flexibility. To map how other executive components are addressed conceptually and methodologically in the literature, a scoping review was carried out.

METHOD

The Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guideline was used. The database search (2017-2022) was carried out on the APA PsycInfo, Medline, Scopus, LILACS, and SciELO databases. A total of 3,473 articles were identified; 1,302 remained after screening. Given the large number of articles, a sample calculation was performed (95% CI and 5% error), with 297 articles randomly selected for full-text reading and 242 studies included for analysis.

RESULTS

There was a predominance of health application studies in adults and older adults and in developed countries. There is relative conceptual consensus that EF are a multidimensional construct; however, there is no explicit identification of the theoretical model used in the studies. A diversity of EF was evidenced, which broadens the understanding of the construct, its assessment, and intervention targets. Furthermore, there was a variety of instruments used to assess these skills, with a predominance of performance tests, often with construct-instrument ambivalence between studies.

CONCLUSIONS

The mapping showed a diversity of skills referred to as EF in addition to the core components and identified the instruments used in their assessment. Greater conceptual and structural clarity and greater methodological care are fundamental to support the assessment of EF and their intervention.
