Systematic review and meta-analysis

Background. Studies of self-efficacy in sports have demonstrated its importance in performance. These have been of English-speaking and Latin American origin, mostly descriptive, qualitative, and relate it essentially to emotional variables; interventions reveal its sources and the way to improve it.

Objective. A meta-analysis and systematic review of self-efficacy studies in high- performance sports in 2015–2022.

Design. The PRISMA method and a flow diagram were used. The databases were SciELO, Dialnet, Redalyc, CORE, REBID, Science Research, Google Scholar, and PubMed. The dimensions of analysis were: descriptions of the articles; methodological approach, and characteristics of the self-efficacy measurements. The keywords “self-efficacy” and “sports,” along with their translations into Spanish, were connected using the OR Boolean operator. The inclusion of “high performance” or “elite” was carefully considered to avoid unintended exclusions.

Results. Thirty-four articles were selected, with soccer and basketball being the most studied sports. Descriptive and correlational designs predominated: increasing relationships between two or more variables with self-efficacy, the studies that discussed interventions were the only ones that addressed longitudinal studies. In the measurements, those of general self-efficacy predominate according to the tasks faced by the athletes; individual self-efficacy is more highly valued; strength and generality are considered in the microanalyses.

Conclusion. Progress has been shown in studies of self-efficacy in high-performance sports. There remain opportunities for longitudinal studies, instruments with sport-specific indicators, analysis of levels and collective self-efficacy that will allow researchers to further explain the phenomenon.
