Empowerment is a core construct in health behavior and an emerging trend in pediatrics. Although it has been suggested as an approach that may promote the person's participation in health care decisions and positive outcomes, little is known about the nature and effectiveness of interventions to support empowerment in families and preschool-age children. The aim of this review is to identify, appraise, and synthesize the evidence on health interventions explicitly using empowerment as an orienting concept with families and their preschool-age children. We identified randomized controlled trials (RCTs) through systematic searches of eight databases for articles published between 1986 and January 2019 and included RCTs that addressed empowerment as a health intervention approach or outcome and that studied families with 3- to 5-year-old children. The application of empowerment theory, the family and child involvement, and the use of behavior change techniques (BCTs) were assessed through appropriate frameworks. Ten interventions were identified, and 50% of them showed positive outcomes. Most studies claimed a theoretical base. However, the studies provided limited details on theory application in intervention planning, implementation, and evaluation, and the children's involvement in the interventions was generally scarce. The most commonly applied BCT was "instruction in how to perform the behavior." We identified 16 potentially effective BCTs. The evidence was not sufficiently robust to determine the effectiveness of empowerment interventions with families and preschool-age children. Additional high-quality studies are needed to produce clearer conclusions. Our results are useful for the design and evaluation of future interventions.
