In this study, \u201cmultimodal\u201d refers to the integration of heterogeneous human-centered evidence streams rather than synchronized perceptual or physiological sensing. We evaluated a low-threshold university-library support model integrating developmental bibliotherapy salons with AI chatbot-supported emotional expression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A convergent mixed-methods feasibility and acceptability design was conducted at a Chinese university. Of 180 baseline respondents, 45 voluntarily registered for a three-week intervention and 38 completed all sessions and post-intervention assessments; 68 non-participating students with complete baseline and follow-up assessments served as a descriptive comparison group. Evidence sources included psychological self-report data, participation records, AI-use feedback, participant evaluations, and semi-structured interviews with nine intervention participants. Quantitative indicators assessed recruitment, retention, acceptability, and exploratory SCL-90 change, while thematic analysis examined participants' affective experiences and perceived mechanisms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>All available intervention places were filled within two days, retention reached 84.4%, and 94.7% of completers reported moderate or considerable benefit. The intervention-group mean SCL-90 change was \u22120.12 points, with an approximate 95% confidence interval of [\u22120.23, \u22120.01]. Because allocation was voluntary and non-randomized, no causal group-by-time intervention effect is claimed. Qualitative findings suggested that bibliotherapy salons supported interpersonal resonance, cognitive reframing, and shared reflection, whereas the AI chatbot provided a private and non-judgmental channel for emotional disclosure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>AI-supported developmental bibliotherapy appears feasible and acceptable as a low-threshold university-library wellbeing service. The findings support feasibility, acceptability, and perceived mechanisms only; they do not establish treatment efficacy, clinical effectiveness, or a neuroscience mechanism. More broadly, the study illustrates how heterogeneous psychological, behavioral, and experiential evidence can be integrated in a naturalistic educational setting.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpsyg.2026.1927988","type":"journal-article","created":{"date-parts":[[2026,10,6]],"date-time":"2026-10-06T04:26:36Z","timestamp":1791260796000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Multimodal data processing for affective perception in AI-supported developmental bibliotherapy: a mixed-methods feasibility study in university libraries"],"prefix":"10.3389","volume":"17","author":[{"given":"Chenyang","family":"Zhou","sequence":"first","affiliation":[{"name":"Jiangsu Second Normal University","place":["Nanjing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Kang","sequence":"additional","affiliation":[{"name":"Jiangsu Second Normal University","place":["Nanjing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,10,6]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"77","DOI":"10.1191\/1478088706qp063oa","article-title":"Using thematic analysis in psychology","volume":"3","author":"Braun","year":"2006","journal-title":"Qual.
