Multiple sclerosis (MS), known for notable heterogeneity in outcomes, makes the evaluation of potential heterogeneity of treatment effect (HTE) significant. Identifying factors that predict individual treatment response is crucial for optimizing patient care, and this study aimed to demonstrate the feasibility (proof of concept) of applying a statistical method to predict individual treatment response in MS trials.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;We developed an individualized response score (RS) to predict treatment response in patients with active secondary progressive MS (SPMS). The RS was a continuous combination of baseline clinical characteristics, including age, sex, previous relapses, EDSS, and disease duration. We used data from the EXPAND trial to train and validate the RS. A training dataset (70% of the data) was used to identify optimal response thresholds for four key outcomes: Expanded Disability Status Scale (EDSS), Timed 25 Foot Walk (T25FW), 9-Hole Peg Test (9HP), and the Symbol Digit Modalities Test (SDMT). The remaining 30% of the data served as a validation set to assess the RS's predictive performance. The continuous RS was binarized (into responder and non-responder) based on the threshold representing the top 25% versus the bottom 75% of the continuous score distribution.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Using baseline profiles, SPMS patients exhibiting varying benefits from Siponimod across different outcomes were successfully categorized as responders or non-responders.

The 20-item Nomophobia Questionnaire (NMP-Q) was developed to assess nomophobia symptoms. This study utilized item response theory (IRT) and classical test theory (CTT) methods to evaluate the NMP-Q's psychometric properties. Data were collected from 5087 adults who completed the NMP-Q. The CTT analyses included the computation of correlation coefficients, including McDonald's <i>ω</i>, Cronbach's <i>α</i>, Guttman's <i>λ</i>2, Guttman's <i>λ</i>6, greatest lower bound, average interitem correlation, Feldt–Gilmer coefficient, Feldt–Brennan coefficient, and Raju's <i>β</i>. IRT analyses included graded response modeling of items, test information function, differential item functioning, and reliability. CTT analysis revealed high reliability coefficients across nine metrics and a four-factor model with good fit indices. IRT analysis showed a strong item fit to the polytomous graded model, indicating the questionnaire's robustness. Based on IRT (both uni- and multidimensional IRT) analyses, we propose a 10-item short version (NMP-Q Short), demonstrating high correlation (<i>r</i> = 0.97) with the original NMP-Q. Our findings provide very good support for the NMP-Q's reliability and construct validity. The items displayed good discrimination and difficulty parameters. The second 10 items of the NMP-Q appeared to be the most informative. The proposed NMP-Q Short offers a valuable option for efficient/rapid and accurate screening. However, additional validation and sensitivity testing are warranted to further establish its usefulness.</p>","PeriodicalId":9081,"journal":{"name":"Brain and Behavior","volume":"15 6","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/brb3.70622","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144256323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
