There has been a recent increase in body-oriented interventions implemented in educational contexts. Body-oriented interventions are grounded on the body-mind relationship, involving body and movement awareness and expression. In this systematic review of the literature on body-oriented interventions implemented in preschool contexts, we review the scope and quality of the quantitative evidence of each type of body-oriented intervention regarding social-emotional competence. Seven databases were searched for randomized controlled trials (RCTs) and quasi-RCTs. Seven core body-oriented intervention programs were found (e.g., play, relaxation, and psychomotricity). Play programs were the most studied and appear to be the most effective to improve social-emotional competence. Nevertheless, the level of scientific evidence was compromised by the lack of studies with high methodological quality.
