As new information becomes available, these probabilities update dynamically, enabling personalized clinical decision-making. However, applying Bayesian Networks to psychological data is challenging because parameter learning in Bayesian Networks can be sensitive to high-dimensional, correlated behavioral indicators across domains. We therefore introduce a Bayesian network\u2013based modeling framework that incorporates Convex Generalized Structured Component Analysis (Convex GSCA) to derive interpretable, low-dimensional summary indexes from multivariate psychological and behavioral data. These summary indexes serve as nodes in a Bayesian network, yielding a parsimonious, theory-consistent model that reproduces clinicians\u2019 treatment recommendations. We illustrate the approach with an empirical application to cognitive behavioral therapy for insomnia (CBT-I), demonstrating how interpretable summary indexes enhance the construction of a Bayesian network for probabilistic, patient-level treatment guidance. We provide commented code and example data to support step-by-step adoption in applied settings.<\/p>","DOI":"10.31234\/osf.io\/wfn5b_v1","type":"posted-content","created":{"date-parts":[[2025,10,23]],"date-time":"2025-10-23T22:43:47Z","timestamp":1761259427000},"source":"Crossref","is-referenced-by-count":0,"title":["Bayesian Networks with Interpretable Summary Indexes for Modeling Clinicians\u2019 Decision-Making in Treatment Recommendation for Mental Disorders"],"prefix":"10.31234","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9237-0388","authenticated-orcid":true,"given":"Gyeongcheol","family":"Cho","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Younyoung","family":"Choi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sooyeon","family":"Suh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"15934","container-title":[],"original-title":[],"deposited":{"date-parts":[[2025,10,23]],"date-time":"2025-10-23T22:43:47Z","timestamp":1761259427000},"score":1,"resource":{"primary":{"URL":"https:\/\/osf.io\/wfn5b_v1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,10,23]]},"references-count":0,"URL":"https:\/\/doi.org\/10.31234\/osf.io\/wfn5b_v1","relation":{},"subject":[],"published":{"date-parts":[[2025,10,23]]},"subtype":"preprint"}}
