Immediate Changes in Perceived Person-Centered Care and Technological Competency Following a One-Day Collective Training Program Among Mongolian Nurse Managers and Nurses Nominated for Managerial Roles: A Pilot Pre–Post Study

<jats:p>Background/Objectives: Person-centered care (PCC) and the Technological Competency as Caring in Nursing (TCCN) theory are increasingly emphasized in nursing leadership, but no published study has evaluated a PCC/TCCN training program among Mongolian nurse managers. This uncontrolled, single-group pilot pre–post study examined immediate changes in nurse managers’ self-reported PCC and TCCN perceptions following a one-day collective training program. Methods: The program was delivered on 30 October 2025 during the 2nd International Nursing Symposium in Mongolia. Using convenience sampling, hospitals were invited to send nurse managers who were currently in post or senior nurses who had been formally nominated for such a role. Of 50 attendees, 30 met a pre-specified role-eligibility criterion and formed the matched pre–post analytic sample. Participants completed Mongolian versions of the Person-Centered Care Instrument (PCCI) and the Perceived Technological Competency as Caring in Healthcare Providers Instrument (TCCHI) immediately before and after the program. Pre–post differences were assessed with Wilcoxon signed-rank tests, effect sizes for the Wilcoxon signed-rank test (r = z/√N), and Holm–Bonferroni correction across 16 comparisons. Results: Total and all concept-level PCCI and TCCHI scores were higher after the program than before it, all 16 comparisons remained significant after correction, and the effect sizes were moderate to large (r = 0.41–0.61). The median within-person change was +22.0 points (95% CI 7.0 to 35.5) for the total PCCI score and +24.0 points (95% CI 10.5 to 38.0) for the total TCCHI score (Hodges–Lehmann estimates). Conclusions: In this small convenience sample of Mongolian nurse managers and senior nurses formally nominated for managerial roles, self-reported PCCI and TCCHI scores increased immediately after a one-day training program. Because the study used a single-group design without a control group, employed instruments not yet fully validated in Mongolian, and included no follow-up, these findings are preliminary evidence of an association rather than proof of program effectiveness. Larger, controlled studies with follow-up are needed. Trial Registration: TCTR20260513001, registered retrospectively on 13 May 2026, after data collection had been completed.</jats:p>
