Although considerable research uses symptom scales to examine this relation, few studies use longitudinal, real-time methods focused on pediatric irritability. This study leveraged an ecological momentary assessment (EMA) protocol, assessing bidirectional associations between momentary irritability symptoms and daily sleep duration in a transdiagnostic pediatric sample enriched for irritability. METHODS: = 12.58 years, SD = 2.56 years; 74% male; 68.8% White) completed digital, in vivo surveys three times a day for 7 days. For a subset of youth, their parents also completed the EMA protocol. Trait irritability was measured using youth-, parent-, and clinician-report to test its potential moderating effect on the association between sleep duration and momentary irritability. RESULTS: Results from multilevel modeling dynamically linked sleep to irritability. Specifically, according to youth- and parent-report, decreased sleep duration was associated with increased morning irritability (bs ≤ -.09, ps < .049). A bidirectional association between parent-reported nightly sleep duration and anger was found-increased evening anger related to decreased nightly sleep duration, and decreased sleep duration related to increased morning anger (bs ≤ -.17, ps < .019). Trait irritability moderated this association, which was stronger for more irritable youth (b = -.03, p < .027). CONCLUSIONS: This study adds to the literature and suggests sleep-irritability dynamics as a potential treatment target.","journal":"Journal of Child Psychology and Psychiatry","year":2024,"id":439927,"datarank":0.4883810419383447,"base_score":2.302585092994046,"endowment":2.302585092994046,"self_citation_contribution":0.3453877639491069,"citation_network_contribution":0.14299327798923778,"self_endowment_contribution":0.3453877639491069,"citer_contribution":0.14299327798923778,"corpus_percentile":null,"corpus_rank":null,"citation_count":9,"citer_count":8,"citers_with_citation_signal":5,"citers_with_endowment":5,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9589,"is_data_producer":true,"deposit_databanks":{"ClinicalTrials.gov":["NCT00018057","NCT00025935"]},"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2024-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1067465,"name":"Miryam Kiderman","orcid":"0000-0002-2701-8484","position":1,"is_corresponding":false},{"id":397270,"name":"Katharina Kircanski","orcid":"0000-0002-6546-5584","position":2,"is_corresponding":false},{"id":295777,"name":"Elise M.
