In order to assess the effectiveness of videotapes in teaching mental state examination, two groups of medical students, one who had received videotape teaching and one not exposed to videotapes, are compared in their ability to observe accurately the mental state during a live interview. Accuracy of observation was assessed by obtaining a measure of the students' ability to shift from an incorrect opinion about a patient to a more accurate assessment following the live interview. Students who had received videotape teaching were able to make more accurate judgements than those who had not. This ability was not related to certain personality attitudes measured, nor to an ability to detect subjective elements in the interview, nor is it reflected in their examination results. The only significant variable found to influence this ability was whether or not the student had received videotape teaching.
为了评估录像带在精神状态检查教学中的有效性，对两组医学生进行了比较，一组接受了录像带教学，另一组未接触过录像带，比较他们在现场访谈中准确观察精神状态的能力。通过衡量学生在现场访谈后从对患者的错误看法转变为更准确评估的能力来评估观察的准确性。接受录像带教学的学生比未接受录像带教学的学生能够做出更准确的判断。这种能力与所测量的某些个性态度无关，与在访谈中检测主观因素的能力无关，也没有体现在他们的考试成绩中。发现影响这种能力的唯一显著变量是学生是否接受了录像带教学。
