Authors replyThe authors would like to thank Dr. Dolmans for her thoughtful commentary on our study examining residents' use of external information during self-assessment of their performance (Plant et al. 2012).In her piece entitled ''Self-assessment and dialogue: can it improve learning?'', Dr. Dolmans (2012) discusses the importance of dialogue in the self-assessment process. As she points out, residents in our study had the opportunity to discuss their performance during facilitated debriefings immediately following a simulation exercise and some took the initiative to discuss their experiences with peers outside of the formal learning activity. These dialogues undoubtedly provided external information and an opportunity for active interpretation of information, crucial aspects of self-assessment (Sargeant et al. 2010). Interestingly, the study interview itself allowed for a dialogue between the interviewer and interviewee and may have affected the self-assessment process as well. While the interviewer did not provide any formal feedback, the social interaction of the interview allowed the residents to monologue and reflect on their performance. Our study demonstrates that it may be impossible to examine self-assessment in action without affecting the process itself.Dr. Dolmans also comments on the good correlation between the residents' selfassessment scores immediately after the simulation exercise and the observers' ratings of their performance. The residents' completed their first self-assessment after the group debriefing and their scores may, in part, reflect the feedback they received during the group debriefing. This leads Dr. Dolman's to comment that the debriefing may improve the ''accuracy'' of their self-assessment and to question why the subsequent video review made them less accurate. We agree that the effect of video review on this process is an interesting area for further investigation. In this study, however, we avoided drawing any conclusions This reply refers to the article available at
