Eleven teams delivered the KISMET intervention comprising cognitive-behavioral and peer support, combined with optional pharmacological reatment. Ten teams participated in the TAU condition. We collected data between October 2022 and July 2024. The primary outcome was self-reported smoking cessation at 12\u00a0months, verified through exhaled carbon monoxide levels below 10 parts per million. Secondary outcomes included depression and anxiety (HADS), severity of psychotic symptoms (PANSS-6), quality of life (SF-12), disease self-management (PAM-13), lipid profile, blood pressure, body mass index, glucose level, and physical fitness. Crude and adjusted linear and multivariable logistic regression and mixed model analyses were performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0033291726104516_sec3\" sec-type=\"results\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Eighty-nine participants were included in the KISMET intervention and 44 in TAU. Smoking cessation rates were significantly higher in the KISMET group at 3\u00a0months (OR 12.1, 95% CI 1.4 to 103.7) and at 12\u00a0months (OR 4.2, 95% CI 1.0 to 17.2) but not at 6\u00a0months (OR 1.9, 95% CI 0.5 to 6.9). No significant differences between groups were found for secondary outcomes.
