PURPOSE To identify and assess the clinimetric properties of psychological, cognitive, and social competence assessment tools relevant to physical activity for school-aged children (5-17 years) with neurodevelopmental disabilities. METHODS Seven electronic databases were searched. Study findings and methodologies were evaluated using the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) checklist. Psychometric strength of assessment tools was determined using Grading of Recommendations Assessment, Development and Evaluation principles (GRADE) (Trial registration: CRD42020180616). RESULTS Study criteria were met by eight subscales from the BRIEF2, DMQ17, QI-Disability, SAID, and SDQ. Most subscales examined psychological competence (n = 5), with fewer addressing social competence (n = 2), or cognitive competence (n = 1). Validity was moderate to high strength for most subscales. Reliability was of moderate and unclear strength for two subscales. A five-level decision tree was devised to summarise: (1) physical literacy domains/elements, (2) populations, (3) assessment focus, (4) required resources, and (5) psychometric evidence. CONCLUSIONS Subscales are available to assess psychological, cognitive, or social competence. For school-aged children with neurodevelopmental disabilities, these have moderate to high strength psychometric support. A decision tree will assist practitioners in subscale selection. Future studies are needed to establish gold standard assessment of physical literacy for this population.IMPLICATIONS FOR REHABILITATIONPsychological Activity Competence can be measured for children with neurodevelopmental disabilities, subscales from The Behaviour Rating Inventory of Executive Function, Second Edition (BRIEF2; The Dimensions of Mastery Questionnaire 17.0 (DMQ17); and The Quality of Life Inventory-Disability (QI-Disability).Cognitive Activity Competence can be measured using a subscale from The Scale of Attention in Intellectual Disability (SAID).Social Activity Competence can be measured using subscales from the BRIEF2, and The Strengths and Difficulties Questionnaire (SDQ).Clinicians can use the Physical Literacy decision tree to guide selection of these tools.
