{"doi":"10.1093/jpepsy/jsaf007","title":"Preliminary data examining associations of fatigue subtypes with pain, pain interference, sleep quality, and affect across 14 days in adolescents with chronic musculoskeletal pain and pain-free controls","abstract":"OBJECTIVE: This preliminary study analyzed existing data from a larger study to characterize fatigue subtypes (general, cognitive, and sleep-related) across 14 days in adolescents with chronic musculoskeletal (MSK) pain and pain-free controls. A secondary exploratory aim was to determine whether fatigue subtypes were associated with next-day pain intensity, pain interference, sleep quality, or positive or negative affect. METHODS: Participants were 26 adolescents with chronic MSK pain and 26 pain-free controls matched on age and sex who completed a daily diary assessing fatigue subtypes, pain intensity, pain interference, sleep quality, and affect for 14 consecutive nights. Data were aggregated across all nights for between-group comparisons, and dynamic structural equation models were used to determine how fatigue subtypes were associated with pain, sleep, and affect from one day to the next. RESULTS: Averaging across 14 days, participants in the MSK group reported greater total fatigue and fatigue subtypes than participants in the control group (all p's < .001). Averaging across days, participants in the MSK group reported higher general fatigue than cognitive (p = .03) or sleep-related fatigue (p = .053). In the exploratory within-person analysis, previous day's cognitive fatigue (-0.10, p < .01) and general fatigue (-0.08, p < .01) were associated with worse next-day sleep quality in the MSK pain group. In the control group, cognitive fatigue was associated with greater next-day pain intensity (.04; p < .01) but lower next day pain interference (-0.03; p < .001). CONCLUSIONS: Results preliminarily suggest fatigue subtypes are prevalent and impactful in adolescents with chronic MSK pain. Future replication of results is needed.","journal":"Journal of Pediatric Psychology","year":2025,"id":532123,"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":3,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.8451,"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":334487,"name":"James Peugh","orcid":"0000-0002-1134-5667","position":1,"is_corresponding":false},{"id":414439,"name":"Christopher D.
