<p>Considering the criticality of post-simulation debriefings for skill development, more evidence is needed to establish how specific feedback design features might influence teams’ cognitive and metacognitive processing. The current research therefore investigates the effects of multisource feedback (MSF) and guided facilitation with video review, for both cognitive processing and reflective (meta-cognitive) behaviors during post-simulation debriefings. With a sample of 174&#xa0;s-year dental students, randomly assigned to 20 teams, the authors conducted high-fidelity simulations of patient emergencies, followed by post-simulation debriefings, using a 2 × 2 factorial design to test the effects of MSF (present vs. absent) and guided facilitation with video review (present vs. absent). According to an ordered network analysis, designed to examine feedback processing levels (individual vs. team) and depth (high vs. low), as well as the presence of metacognitive reflective behaviors (evaluative behaviors, exploration of alternatives, decision-oriented behaviors), teams that received both MSF and guided facilitation demonstrated significantly deeper, team-level processing and more frequent evaluative behaviors. Teams that received only guided facilitation exhibited the highest rates of low-level, individual processing. However, facilitation also produced an additive effect that fostered reflection and a shift from individual- to team-oriented processing. In contrast, MSF alone produced the lowest levels of evaluative behaviors; without facilitation, it does not support team reflection. These results establish that combining MSF with guided facilitation and video review creates synergistic effects for team reflection. Even if MSF can highlight perceived performance discrepancies, teams need facilitation to interpret and learn collaboratively from the feedback.</p>
