Although cognitive remediation (CR) has emerged as a promising approach to improving cognitive and functional outcomes in schizophrenia, its effectiveness among inpatients and within hospital environments—where opportunities to practice skills in real-world contexts are limited—remains unclear. Here, we aimed to establish the feasibility and initial efficacy of a short, ecological virtual reality-based CR training (CR-EVR) in acute mental health inpatient settings. Efficacy was assessed at four levels: training engagement, near transfer, far transfer, and ecological transfer. Twenty-three inpatients with schizophrenia (Male: 33.3 ± 8.5; 4 Female) completed 8, 20-min CR-EVR sessions, with exercises training the cognitive abilities of inhibition, planning, working memory, shifting, self-initiation, persistence, and attention. Their cognitive functioning, schizophrenia symptoms, functional capacity, and participation in occupations were evaluated pre- and post-training to address four levels of effectiveness. Of the recruited participants, 25.8 % dropped out. Inpatients who completed the full protocol reported high rates of satisfaction (1-not satisfied; 5-very satisfied)) from the intervention (Median = 4, IQR:3.5–5). Post-training, significant improvements were found in the trained cognitive components (intervention engagement: −6.58 &lt; t/Z &lt; 2.02, <em>p</em> &lt; .05), general cognitive functioning (−2.59 &lt; t/Z &lt; 2.29, <em>p</em> &lt; .05), functional capacity (<em>t</em> = −2.9, p &lt; .05), and diversity of participation in everyday activities (<em>t</em> = −3.36, p &lt; .05). This preliminary study suggests that CR-EVR may be a feasible and practical tool to enhance cognitive and ecological outcomes in short-stay acute inpatient settings. Subject to further research, such intervention may be considered an add-on to current practices that promote recovery and health among inpatient populations.</p></div>","PeriodicalId":38119,"journal":{"name":"Schizophrenia Research-Cognition","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2215001324000271/pdfft?md5=f5789124689b40f14b3d8fb575785eef&pid=1-s2.0-S2215001324000271-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142088849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
