The study compared equal- and differential-weighted scores for LOC and OC skills, with three fitness and two physical activity (PA) outputs during guided active play (GAP). Methods: Children\u2019s (n = 82; 7.6 \u00b1 1.5 years) TGMD-2 LOC and OC differential factor weights were estimated with Exploratory Factor Analysis (EFA) and compared to equal weights with multiple linear regression (two, five, and eight predictors) and Chi-square analyses. Predictor variables included fitness, BMI, sex, age stages, and PA assessed by energy expenditure (PAEE) and intensity (MVPA) estimated using accelerometry during 1 h GAP. Results: EFA supported a two-factor structure (variance explained = 51.1%) with \u22650.500 loadings for 9\/12 skills. Differential- and equal-weighted LOC and OC scores showed varied contributions from individual skills. Multiple linear regression analysis showed similar explained variances (R2) of 53% (PAEE), 40% (MVPA), 31% (OC), and 14% (LOC) for equal or differential scores with eight predictors. Although \u03b2 coefficients varied, going from two, five, and eight predictors, the impact of equal and differential weights was comparable. Chi-square analysis indicated high OC associated with MVPA (X2 (4) = 9.42, p \u2264 0.05), LP, and STR with PAEE. Conclusions: TGMD-2 outputs with equal- and differential-weighted scores are adequate for clinical\/educational use, which show similar relationships with PA and HRF variables. Differential-weighted TGMD-2 scores comprise different contributions of movement skills and may hold promise for intervention studies focused on varied or target tasks and movement abilities.<\/jats:p>","DOI":"10.3390\/children12121615","type":"journal-article","created":{"date-parts":[[2025,11,27]],"date-time":"2025-11-27T10:25:16Z","timestamp":1764239116000},"page":"1615","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Computing and Evaluating Relationships Between Equal and Differential Factor Weighting for Fundamental Movement Skills and Physical Activity with Guided Active Play During Childhood"],"prefix":"10.3390","volume":"12","author":[{"given":"Glory","family":"Madu","sequence":"first","affiliation":[{"name":"School of Kinesiology and Health Science, Faculty of Health, York University, Toronto, ON M3J 1P3, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victoria","family":"Kwong","sequence":"additional","affiliation":[{"name":"School of Kinesiology and Health Science, Faculty of Health, York University, Toronto, ON M3J 1P3, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dusan","family":"Calic","sequence":"additional","affiliation":[{"name":"School of Kinesiology and Health Science, Faculty of Health, York University, Toronto, ON M3J 1P3, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taylor","family":"Cleworth","sequence":"additional","affiliation":[{"name":"School of Kinesiology and Health Science, Faculty of Health, York University, Toronto, ON M3J 1P3, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9841-1996","authenticated-orcid":false,"given":"Angelo","family":"Belcastro","sequence":"additional","affiliation":[{"name":"School of Kinesiology and Health Science, Faculty of Health, York University, Toronto, ON M3J 1P3, Canada"},{"name":"Muscle Health Research Centre, Faculty of Health, York University, Toronto, ON M3J 1P3, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1663","DOI":"10.1007\/s40279-016-0495-z","article-title":"Correlates of Gross Motor Competence in Children and Adolescents: A Systematic Review and Meta-Analysis","volume":"46","author":"Barnett","year":"2016","journal-title":"Sports Med."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"781","DOI":"10.1080\/02640414.2017.1340660","article-title":"Fundamental Motor Skills: A Systematic Review of Terminology","volume":"36","author":"Logan","year":"2018","journal-title":"J.
