{"doi":"10.1371/journal.pone.0312254","title":"The measurement reliability and equivalence of print versus online versions of the Youth Activity Profile","abstract":"PURPOSE: The Youth Activity Profile (YAP) is a 7-day self-report designed to quantify physical activity and sedentary behaviors among youth. This study evaluated the reliability of the online version of the YAP and equivalence with the paper-based version. METHOD: A total of 2,490 participants from 17 schools in Iowa and Texas completed the YAP. Each classroom was randomly assigned to complete either the print or online version twice. A variance components model was used to assess the test-retest reliability and equivalence testing was also applied. RESULTS: Both paper and online versions had similar reliability for the PA estimates in school (ICCprint = 0.69-0.91; ICConline = 0.54-0.84), at home (ICCprint = 0.72-0.83; ICConline = 0.64-0.94), PA at weekend (ICCprint = 0.33-0.72; ICConline = 0.39-0.70), and SB (ICCprint = 0.69-0.90; ICConline = 0.66-0.80). The two versions were statistically equivalent for most YAP items except for recess. CONCLUSION: The online YAP appears to be a reliable assessment of physical activity and sedentary behavior in youth populations.","journal":"PLoS ONE","year":2025,"id":542880,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":1,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.7131,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":744689,"name":"Philip M.
