Background: Guided reflection during a debriefing after the simulation is a critical component of learning and is essential for clinical judgment development. However, the literature describing student-centered reflection during debriefing is only beginning to emerge. Purpose: This study aimed to explore concordance between student-centered reflection concept characteristics and describe students' experiences related to reflection during an optimal simulation debriefing. Methods: This was a descriptive, mixed-methods study. Results: Quantitative responses (N = 175; 67% response rate) confirmed participants' concordance with student-centered reflection concept analysis attributes, antecedents, and consequences. Analysis of open-ended questions highlighted internal and external factors influencing students' reflections. A recurring theme was the importance of faculty and peers in creating a safe, supportive environment for reflections. Conclusions: Findings support the concordance of student-centered reflection and provide valuable insights into the internal and external factors influencing this reflection.
