Purpose: This study was conducted to evaluate the effects of different methods of information delivery(information provided by nurses vs. information provided by video) on environmental stress and the satisfaction of nursing needs in families of intensive care unit patients. Methods: A nonequivalent pretest-posttest control group design was used in this study. The data were collected from March 24 to May 7, 2009. The subjects, 52 family members of ICU patients (26 for the control group, 26 for the experimental group), were selected from a hospital located in Gyeonggido. Information was given by video to the experimental group whereas the information was directly given by nurses to the control group. Results: Environmental stress and satisfaction of nursing needs were not statistically different between the two groups. Conclusion: The findings of the study suggest that the information given by video may be compatible with that given by nurses. Therefore, nurses need to be flexible in using these different methods to maximize the benefits of direct and indirect information delivery method for families in ICU setting.
