{"doi":"10.1016/j.jaacop.2023.01.001","title":"Substance Use Disorders and Psychiatric Illness Among Transitional Age Youth Experiencing Homelessness","abstract":"Objective Transitional age youth experiencing homelessness (TAY-EH) bear a high burden of substance use disorders (SUD) and psychopathology. However, limited data exist on the co-occurrence and interactions between these diagnoses in this marginalized group. This study sought to identify rates of single and co-occurring SUD and psychiatric diagnoses among a sample of TAY-EH and to investigate associations between psychopathology and prevalence/severity of SUD in this group. Method TAY-EH accessing a low-threshold social service agency in a large metropolitan area completed psychosocial and diagnostic interviews to assess for SUD and psychopathology. Analyses examined rates of single and co-occurring disorders and associations between burden of psychopathology and presence/severity of SUD. Results 140 TAY-EH completed the assessment; the majority were youth of color (54% Black/African American, 16% Latinx). Fifty-seven percent identified as male. Rates of single and co-occurring psychiatric disorders and specific SUDs (cannabis use disorder (CUD) and alcohol use disorder (AUD)) were notably high. An increasing number of psychiatric diagnoses was significantly associated with elevated CUD/AUD prevalence and severity. Mood, anxiety, Attention Deficit-Hyperactivity, and antisocial personality disorders were significantly associated with elevated CUD/AUD prevalence and severity, as was suicidality (p <0.05 for all). Conclusion This study reveals a complex overlay of SUD and psychopathology facing TAY-EH, with a significant association between co-occurring psychopathology and severity of CUD/AUD. To our knowledge, this is the first study to examine associations between specific psychopathology and severity of SUD among TAY-EH. Further research into the mechanistic and temporal links between these conditions is needed to inform tailored treatment interventions.","journal":"JAACAP Open","year":2023,"id":339309,"datarank":0.42498200160843247,"base_score":2.833213344056216,"endowment":2.833213344056216,"self_citation_contribution":0.42498200160843247,"citation_network_contribution":0.0,"self_endowment_contribution":0.42498200160843247,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":16,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.955,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1072908,"name":"Elizabeth S.
