Abstract
This study using computer graphics based Virtual Patients of Mania and Schizophrenia is the first of its kind in Psychiatry in India. In Psychiatry, Virtual patients instead of live patients offer many advantages in cases of violence, suicide, complex phenomenology and where typical cases are few. 104 medical students of Maharajah's Institute of Medical Sciences, Nellimarla, India volunteered to rate the 3min 20 sec animation graphics video portraying Ravi as Mania and George as Schizophrenia using Young Mania Rating Scale (YMRS) and Positive and Negative Symptoms of Schizophrenia (PANSS). 53 students of Fifth Semester in two batches of 28 and 25 were compared with 51 students of Eighth Semester on their scoring patterns. All batches had mean YMRS and PANSS scores above cutoff indicating positive diagnosis but those with at least 5 hour theory exposure prior had significantly higher scores on PANSS and YMRS. The major differences in scoring were on Negative symptoms and YMRS. In conclusion, computer generated 3 d graphic virtual patients are quite effective as teaching tools in psychiatry.
