They rated their psychiatric symptoms across five domains\u2014delusions, hallucinations, anxiety, depression, and perceived stress\u2014using an 11-point Likert scale at baseline, 1 week, 8 weeks, and 16 weeks. Test\u2013retest reliability was assessed using intraclass correlation coefficients (ICCs) between baseline and 1-week ratings. Concurrent validity was determined by correlating app-based ratings with established self-report and clinician-administered scales, including the Eppendorf Schizophrenia Inventory, Hamilton Program for Schizophrenia Voices Questionnaire, Beck Depression Inventory, Generalized Anxiety Disorder-7, and Perceived Stress Scale. The accuracy of the app's depression rating was assessed using receiver operating characteristic (ROC) analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>ICCs for test\u2013retest reliability were high across all symptom domains, ranging from 0.741 to 0.876 ( p\u2009&lt;\u20090.001).
