Abstract(s)

Purpose: To analyse possible differences between the anxiety levels of patients who receive additional information about the MRI scan, and patients who receive only basic instructions from the hospital, and to verify if there is variation in anxiety levels of patients before and after the examination, and relate them to gender, age, education level, and previous MRI examinations. Methods and Materials: The total sample of 60 patients was divided into a control group and an experimental group, and each one divided into two subgroups before and after the exam, and then it was applied STAI form Y-1 to both, after the sociodemographic questions. Results: At a 95% confidence interval, the mean difference between the control group, before and after, ranged from 7.210 and 20.624. The value of the Student’s t test was 4.153 (df=58 and 2-tail sig=0.000). The mean difference between the experimental group before and after, ranged from 6.112 and 19.305. The value of the Student’s t test was 3.856 (df=58 and 2-tail sig=0.000). Using Spearman’s Ro, there are some correlations between the sociodemographic variables and their levels of anxiety. The level of anxiety can be changed by many reasons, one and the most important is when the patient has already performed a MRI scan. Conclusion: The main results suggest a significant difference in both groups, among the subgroup before and after, that let us concluded that after the MRI exam patients are less anxious. We also conclude that who has previously performed an MRI scan has smaller values of anxiety.
