{"doi":"10.1111/fare.12995","title":"Mother–child similarity during observed interactions: Links with mother and child effortful control","abstract":"Objective: We examined whether mothers' and child's regulatory capacity, measured by effortful control (EC) and its facets, is associated with variance in mother-child within-dyad similarity in multiple aspects of positive emotions and behaviors during their interaction. Background: Both parents' and children's self-regulation capacities may help them to modulate their behaviors and emotions to be mutually responsive to and harmonious with their interaction partner. Methods: = 147). Mothers completed a set of questionnaires regarding themselves, their child, and demographics, and mother-child interactions were observed during three cooperative tasks. We estimated mother-child within-dyad similarity during their brief interaction using the Q-correlation method. Results: Mothers' general EC was statistically associated with greater mother-child similarity, but children's EC was not. When testing the subscales of EC, greater mother-child similarity was associated with mother's higher attentional control, child's better attention focusing, child's lower levels of low intensity pleasure, and older child age. Conclusion: Mother's higher attentional control and child's better attention focusing are associated with greater mother and child within-dyad similarity during their interactions. Implications: This study highlights the importance of considering child and mother self-regulation for intervention efforts to better understand how dyads match and co-modulate their behaviors and emotions during their interactions.","journal":"Family Relations","year":2024,"id":470529,"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":2,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.956,"is_data_producer":false,"deposit_databanks":null,"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":291615,"name":"Martha Ann Bell","orcid":"0000-0001-9222-0374","position":1,"is_corresponding":false},{"id":453326,"name":"Kirby Deater‐Deckard","orcid":"0000-0003-4151-2152","position":2,"is_corresponding":false},{"id":1263157,"name":"Yelim Hong","orcid":"0000-0001-8605-914X","position":0,"is_corresponding":true}],"reference_count":67,"raw_metadata":null,"created_at":"2026-07-19T02:05:40.740958Z","pmid":"40028239","pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
