ABSTRACT

This study had two objectives: (a) to compare the level of patients’ understanding in the consent process when information is provided in text-based form with patients’ level of understanding when information is provided in photo-novella form (Wave 1); and (b) to compare the level of patients’ understanding when the routine informed consent process is supplemented with text-based information sheets (Wave 2). Twenty healthy male volunteers were consecutively recruited and randomly allocated to Group A (text-based form) or Group B (photo-novella form). Understanding was measured three times: at Wave 1, at Wave 2, and one week after Wave 2 (Wave 3). The choice type objective understanding (OU) measured at Wave 1, Wave 2, and Wave 3 was significantly higher in Group B than Group A. Both OU and subjective understanding (SU) increased from Wave 1 to Wave 2, but the changes were not statistically significant between the two groups. In conclusion, OU was higher for the photo-novella group than for the text-based group after receiving the information and remained so up until one week after the routine informed consent process. These results suggest that medical information for informed consent should be provided in photo-novella form.
