{"doi":"10.1111/sltb.12793","title":"Being certain that negative events will happen or that positive events will not happen: Depressive predictive certainty and change in suicide ideation over time","abstract":"INTRODUCTION: Relatively little research has examined the precise components of hopelessness that increase vulnerability to suicidal thinking. We examined whether certainty about an absence of positive future outcomes (Certainty-AP) would more strongly predict suicide ideation over time than certainty about negative future outcomes (Certainty-N). METHOD: Young adults (N = 208), ages 18-34 (M = 19.08, SD = 2.22), with either recent suicide ideation, suicide attempt history, or past-year psychiatric diagnosis were assessed four times over 18 months. RESULTS: We used multilevel modeling to assess within-participant differences in suicide ideation over time. Both Certainty-AP and Certainty-N predicted later suicide ideation above and beyond generalized hopelessness and depressive symptoms, when examined in separate models. However, Certainty-AP emerged as a stronger predictor of suicide ideation than Certainty-N when examined in the same model. DISCUSSION: These findings suggest that certainty about an absence of positive future outcomes may have a more unique prospective relationship to SI than certainty about the presence of negative future outcomes. We discuss clinical and theoretical implications of these findings.","journal":"Suicide and Life-Threatening Behavior","year":2021,"id":204453,"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":4,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9564,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2021-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":787344,"name":"Christina Rombola","orcid":null,"position":1,"is_corresponding":false},{"id":429683,"name":"Regina Miranda","orcid":"0000-0001-7282-9545","position":2,"is_corresponding":false},{"id":786782,"name":"Beverlin Rosario‐Williams","orcid":"0000-0003-3429-1291","position":0,"is_corresponding":true}],"reference_count":50,"raw_metadata":null,"created_at":"2026-07-18T23:51:26.121843Z","pmid":"34309062","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":[]}
