Purpose: The purpose of this study was to examine the effects of laughter therapy on postpartum fatigue and stress respon-ses of postpartum women. Methods: The research design was a nonequivalent control group non-synchronized design. The participants were 67 postpartum women who agreed to participate in this study, selected by convenience sampling: (experiment group-33 and control group-34). The data were collected from August 5 to September 30, 2010. The experimental group received laughter therapy from a laughter therapy expert for 60 min, twice a week for 2 weeks, a total of 4 sessions. To evaluate the effects of laughter therapy, postpartum fatigue by self-report questionnaire and cortisol concentration in breast milk were measured. The data were analyzed using the SPSS WIN 13.0 Program. Results: The first hypothesis that "the degree of postpartum fatigue in the experimental group participating in laughter therapy would be lower than that of the control group" was accepted. These findings indicate that laughter therapy has a positive effect on decreasing postpartum fatigue. Conclusion: The finding provides evidence for use of complementary and alternative nursing in Sanhujori facilities and obstetric units to reduce postpartum women's fatigue.

Data was collected from October 1 to November 22, 2013. Experimental group participated in laughter therapy six times, once a week for 60 minutes of each session. Questionnaires were used to measure pretest and posttest levels of depression and laughing index. Results: At the end of six-week intervention, depression score (z=-2.95 p=.003) and laughter index score (z=-2.81 p=.005) was significantly decreased in the experimental group compared to the control group. Futhermore, there was a significant difference in the depression scores of the experiment group at the posttest, but no signigicant difference was found between the two groups. Conclusion: The study results suggest that the laughter therapy is an effective intervention to reduce the depression but helpful to enhance the laughing index. Therefore, it is expected that laughter therapy will serve as an emotional nursing intervention for elderly patients with depression.

Purpose: This study was to determine the effects of laughter therapy on stress response and pain of military patients with low back pain. Method: The subjects in the experimental group received 3-sessions of laughter therapy on 3 consecutive days. The primary outcome measures were state anxiety, depression, blood pressure, pulse rate and pain. Result: After 3 sessions of laughter therapy, the scores of state anxiety(p=.046), depression(p=.028) and pulse rate(p=.003) were significantly lower and diastolic blood pressure(p=.038) was significantly higher in the experimental group than those in the control group. The level of pain(p=.711) was not different significantly between two groups. Conclusion: Laughter therapy could be an effective strategic intervention for military patients with low back pain to reduce the level of anxiety and depression. Further studies are needed to determine long-term effects of laughter therapy and its effects on cardiovascular system and pain.

Objective: This study is based on a parallax design before and after a non-equivalent control group to examine the effects of laughter therapy on the anxiety, depression, and stress in patients with cancer admitted to a nursing hospital. Design: A randomized controlled trial. Methods: Data collection was conducted on 34 patients who agreed to participate in the study among patients admitted to E Cancer Hospital from September to November 2018. Laughter treatment interventions were performed three times a week for 50 minutes each and a total of eight times. In this study, a tool developed by Spielberger was used to measure state anxiety, a tool developed by Beck was used to measure depression, and the Perceived Stress Scaled eveloped by Cohen was used to measure stress. Results: Anxiety was significantly lower in the experimental group than in the control group (F=10.74, p=0.003). Depression was lower in both the experimental group and the control group that did not participate in the laughter therapy intervention and was not significant (F=0.58, p=0.451). Stress was significantly lower in the experimental group than in the control group (F=4.36, p=0.045). Conclusions: The results of this study suggest that laughter therapy has a positive effect on reducing anxiety and stress in patients with cancer admitted to nursing hospitals.
