The effect of engagement interventions on uncertainty and coping of Thai family members of patients in a coma

The purpose of this study was to test the effect of the expressive writing and the expressive talking interventions on uncertainty and coping processes in Thai family members of patients in a coma, and to examine changes in positive emotion, negative emotion, and cognitive process word-use over three days. A quasi-experimental pretest-posttest, three group design was conducted with 45 Thai family members of patients in a coma who were in the intensive care units (ICU) at a hospital in Thailand. Three ICUs were randomly assigned into groups: the expressive writing, the expressive talking, and the control group. Participants of the expressive writing group (n = 15) were asked to write about their thoughts and feelings following standard guidance for expressive writing, those of the expressive talking group (n = 15) were interviewed with questions guided by the story path approach, whereas those of the control group (n = 15) did not receive any specific interventions. Participants completed the Thai version of the Mishel Uncertainty in Illness Scale-Family Member Form and the Thai version of the revised version of the Ways of Coping Scale before and after the interventions.
