Effects of Holistically Conceptualised School-Based Interventions on Children's Physical Literacy, Physical Activity, and Other Outcomes: A Systematic Review.

BACKGROUND

Schools are a key setting for promoting children's physical literacy development. This review aimed to identify school-based interventions that adopted a holistic conceptualisation of physical literacy and examine the effects on children's physical literacy and any other outcomes, including physical activity (PA).

METHODS

Searches were conducted in seven databases (APA PsycINFO, EMBASE, ERIC, CINAHL, Global Health, MEDLINE Complete, SPORTDiscus with Full Text), and Google and Google Scholar, to identify articles published since 1/1/2017. Studies were included if they (i) adopted a holistic conception of physical literacy as represented by the Australian Physical Literacy Framework (APLF), (ii) were grounded in movement, (iii) assessed three or more domains of learning (either quantitatively or qualitatively), and (iv) included children aged 5-14 years. Quantitative research designs needed to provide pre-and post-intervention measures, whereas qualitative designs (e.g. post-intervention interviews) did not. Study selection, data extraction and quality assessment were conducted independently by teams of two authors. For intervention effects, quantitative and qualitative data were synthesised separately. For quantitative data, level of evidence for intervention effects was assessed by physical literacy domain and/or elements/items by examining the proportion of tests with a significant change in the expected direction. Qualitative data were synthesised using the framework synthesis method and mapped to a framework that included APLF domains/elements, PA, and additional outcomes.

RESULTS

Twelve interventions with 1,427 participants from seven countries were identified: six physical education-based, three afterschool, one structured recess, and two multicomponent. All studies assessed the physical domain quantitatively, with strong positive evidence of intervention effects for the controlled designs (10 of 15 tests). For the affective and cognitive domains, evidence was mixed, and there was no evidence for interventions improving the social components of children's physical literacy (although this was understudied). Most studies assessed PA and one measured cognitive performance; however, there was no evidence for positive intervention effects (i.e. ≥35% of tests reporting an improvement) for either outcome. Five studies assessed intervention effects qualitatively, with positive results reported for all physical literacy domains, PA, and cognitive performance.

CONCLUSIONS

Holistic interventions in schools can improve the physical domain of children's physical literacy. For wider benefits, future interventions should aim to develop all facets of physical literacy, especially domains of learning less frequently targeted and examined.
