Schizophrenia (SZ) and bipolar disorder (BP) are associated with poor response inhibition, but it is unknown whether SZ and BP show incentive-related improvements to the same degree as healthy controls (HC). To investigate this question, reaction time data from an incentivized Stroop-style task were analyzed from 37 SZ, 26 B P, and 33 H C. We examined: 1) group differences in mean reaction time, 2) group differences in response caution and in rate of processing task-relevant information derived from a computational approach (drift diffusion modeling), and 3) clinical and cognitive correlates of drift diffusion parameters in SZ and BP groups. When incentives were introduced, both HC and BP showed significantly faster response speed, but SZ did not show the same pattern of improvement as a function of incentives. Computational analyses indicated that groups did not significantly differ in response caution, but that both SZ and BP had a slower information processing rate compared to HC. In SZ, slow information processing rate was related to poor cognition; positive and negative symptoms were associated with impairments in information processing rate, but in opposite directions (i.e., increased information processing rate was associated with positive symptom severity; decreased information processing rate was associated with negative symptom severity). Our findings suggest impaired information processing rate may contribute to poor response inhibition in both SZ and BP, whereas response caution is intact in both disorders. However, SZ is distinguished from BP by a failure to enter an overall motivated state and decrease response speed when incentivized.</div></div>","PeriodicalId":16868,"journal":{"name":"Journal of psychiatric research","volume":"183 ","pages":"Pages 282-288"},"PeriodicalIF":3.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143508713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The FUS was developed with a focus on combat veterans, frontline workers, and first responders. We examined its psychometric properties using two samples: a clinical sample (N = 1798) and a crowdsourced sample (N = 10,000).

The FUS demonstrated robust convergent validity with established measures including the PHQ-9, GAD-7, and PCL-5 (r = 0.59–0.66), though correlation with the Columbia-Suicide Severity Rating Scale was modest (r = 0.22). Receiver operating characteristic analyses showed good discrimination of clinical severity based on established measures (AUC = 0.77–0.81) and excellent discrimination between treatment-responsive and help-seeking individuals (AUC = 0.92). The FUS achieves these psychometric properties while avoiding symptom-focused language that could trigger distress, making it particularly suitable for vulnerable populations such as combat veterans, first responders, and trauma survivors.
