{"doi":"10.1038/s44271-025-00344-0","title":"Unhealthy behaviours in disaster survivors are associated with scarcity and present bias","abstract":"Extant research suggests that disaster exposure may induce unhealthy behavior, such as smoking, drinking, and eating disorder symptoms in survivors; however, the underlying the mechanisms of such behavior remain unclear. Using two field experiments in two separate disaster-affected communities in Japan (N = 337) and the Philippines (N = 187), this study found that scarcity and reinforced present-bias were associated with disaster experiences and unhealthy behavior in both locations. These experiments were conducted twice (i.e., 2–3 years and 6 years post-disaster), allowing us to examine the enduring impact of these disasters. Disaster survivors became consistently present-biased, which in turn explains variance in individuals’ health-related decisions, such as body mass index, smoking, and drinking. Combining data from post-disaster field experiments in Japan and the Philippines, the study shows that disaster exposure heightens present bias, which explains variance in increases in smoking, drinking, and BMI among survivors.","journal":"Communications Psychology","year":2025,"id":548866,"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":0.9516,"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":1442553,"name":"Yusuke Kuroishi","orcid":"0009-0003-3418-3642","position":1,"is_corresponding":false},{"id":1151507,"name":"Toyo Ashida","orcid":"0000-0002-0334-121X","position":2,"is_corresponding":false},{"id":330904,"name":"Jun Aida","orcid":"0000-0002-8405-9872","position":3,"is_corresponding":false},{"id":1442554,"name":"Kei Kajisa","orcid":"0000-0002-9062-7303","position":4,"is_corresponding":false},{"id":330905,"name":"Hiroyuki Hikichi","orcid":"0000-0002-7791-464X","position":5,"is_corresponding":false},{"id":1442555,"name":"Takahiro Sato","orcid":"0000-0003-3358-0809","position":6,"is_corresponding":false},{"id":1443037,"name":"Eduardo Lucio","orcid":null,"position":7,"is_corresponding":false},{"id":330906,"name":"Katsunori Kondo","orcid":"0000-0003-0076-816X","position":8,"is_corresponding":false},{"id":455257,"name":"Ken Osaka","orcid":"0000-0001-6885-9514","position":9,"is_corresponding":false},{"id":330903,"name":"Ichiro Kawachi","orcid":"0000-0001-9339-2821","position":10,"is_corresponding":false},{"id":1140510,"name":"Yasuyuki Sawada","orcid":"0000-0002-4167-7697","position":0,"is_corresponding":true}],"reference_count":36,"raw_metadata":null,"created_at":"2026-07-19T02:54:03.053965Z","pmid":"41286118","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":[]}
