The goal of this a quasi-trial model with pre and post-test control group is to determine the effect of laughter yoga on depression and serotonin levels in patients undergoing bariatric surgery.
The main question's it aims to answer are:
The first stage of the data, identifying the patients, was collected by the researcher in the general surgery service of the hospital determined between February-June 2021.The patient information and blood samples, which are the second phase of the data, were collected by the researcher at the same time intervals in the nursing faculty meeting room of the designated university. In order to determine the participants to participate in the research, the participants who met the criteria were contacted by phone and an appointment was requested. Face-to-face Beck Depression Scale was applied to the patients who attended the appointment in the General Surgery service. 158 patients who got 17 points from the Beck Depression Scale were determined among the 62 patients who agreed to participate in the study, the first 31 experimental groups and the second 31 control groups. Before their hospital visit for the interview, the patients were reminded that they should be fasting for blood sample collection and they should be on a 24-hour serotonin free diet. All participants filled the Patient Information Form as a pre-test in the nursing faculty meeting room and gave blood samples for serotonin levels. Laughter yoga was applied to the experimental group twice a week, on Tuesdays and Fridays, for 2,5 months, for a total of 10 sessions (each session 50 minutes) by the researcher after obtaining a laughter yoga practice certificate. Due to the COVID-19 pandemic that started during this study period, the first and last sessions were applied face-to-face, and the other eight sessions of laughter yoga were carried out with an internet program that allows online meetings. Expert opinions from laughter yoga leaders for online applicability of laughter yoga taked. After 10 sessions were applied to the participants, the Beck Depression Scale was re-administered to the participants in the experimental group as a post-test and blood samples were taken again to check the serotonin levels. The Beck Depression Scale was re-administered 5 weeks after the pretest without any intervention in the control group, and blood samples were taken again to determine serotonin levels.

Apart from the first and last sessions, eight sessions of the laughter yoga intervention were held via an Internet program with on-line meeting option due to the COVID-19 pandemic that started in March 2019. For the feasibility of online sessions, opinions were obtained from experts who provide laughter yoga leadership training. |

| Measured by the Beck Depression Scale that laughter yoga would reduce depression | The scale was developed by Beck et al. in 1961. Hisli conducted the Turkish validity and reliability studies of the scale in 1989 . The scale consists of 21 items assessing the symptoms that develop during depression. While the lowest score of the scale is 0, the highest score is 63. Scores between 5 and 9 indicate normal depression; scores between 10-18 indicate mild-moderate depression; scores between 19-29 indicate moderate-severe depression; and scores between 30-63 indicate severe depression. High scores indicate higher levels of depression. The cut-off point of the scale is 17. The reliability analysis of the scale showed that the Cronbach's alpha coefficient is 0.80. In our study, the pre-test Cronbach α of the Beck Depression Scale was calculated as 0.628, while the post-test Cronbach α was calculated as 0.841. | 2,5 months |
| It was measured by the ELISA method by experts in the laboratory environment that laughter yoga would increase serotonin levels. | Before taking blood from the patients, they were asked whether they fasted and followed a 24-hour serotonin-restricted diet. Approximately 6 ml of venous blood samples were taken from the participants with 10 ml injectors and placed into yellow- and red-capped blood collection tubes. The blood samples were centrifuged in the laboratory of the physiology department of the medical faculty of a university. The serum part of the centrifuged blood was placed in godets and kept in the -45 degree-refrigerators until all the blood was collected. Labels containing the patients' names, surnames and dates were attached to the godets. All frozen serums and kits were then allowed to reach room temperature for 15 minutes and processed using the ELISA method. DRG (serotonin fast elisa EIA-5061) brand kits were worked on in accordance with the package insert. The detection range of the kits was 10.2-2500 ng/ml and the sensitivity was 6.2 ng/ml. | 2,5 months |
