About this study
Official title: Effect of Laughter Therapy on Hemodialysis Patients: A Randomized Controlled Study
Internet-based behavioral therapy applications made during the quarantine and isolation period during the pandemic process, and the application of laughter therapy, which is a group-oriented technique that increases the feeling of togetherness and happiness, can be used as an online method to reach large masses. However, since there are a limited number of studies in the literature on online laughter therapy in patients and not all sessions are online in the study, it was thought that more and methodological studies are needed to confirm the effectiveness of the therapy on the applicability of the online platform. Therefore, this study was conducted to evaluate the blood cortisol levels, depression, anxiety, stress levels and quality of life of laughter therapy in hemodialysis patients.
Read the detailed description
In this research, laughter therapy applied to hemodialysis patients; This is an experimental design with pretest and posttest control groups in order to examine the effects on serum cortisol levels, depression, anxiety, stress levels and quality of life. The study will be conducted between April 2021 and September 2022 on 80 patients who are receiving hemodialysis treatment in two Dialysis Centers in Zonguldak city center and meet the inclusion criteria.

Laughter therapyOther
Laughter therapy will be applied for 50 minutes, 12 sessions, 3 days a week. The therapy, which starts with the stimulation of the acupuncture points in the palm and acquaintance with hand clapping for an average of 10 minutes, continues with deep breathing and breathing exercises that include diaphragmatic breathing. The childish games section, which is played to reveal and trigger simulated laughter, is the section where laughter starts as "if" and turns into reality.
The last part is the part where the group makes eye contact for no reason and for no reason, and laughs for at least 3 minutes unconditionally. In the last part, wish meditation and relaxation sessions are performed.

What is being measured
The primary outcome is the main question the study is designed to answer.
Depression, Anxiety, Stress scale
Description: Depression Anxiety Stress Scale (DASS-21) was first developed by Lovibond (1995) as 42 items. The adaptation of the 21-question DASS scale used in the study was made by Henry and Crawford (2005), and it was revealed that the short form could be used. The scale, which was revised by Henry and Crawford, was adapted into Turkish by Yılmaz et al. (2017). In this scale, there are 7 questions each to measure the dimensions of depression, anxiety and stress. The first 7 questions on the scale are about anxiety, 7 questions between 8-14 are about depression and 7 questions between 15-21 are about stress. The scale has a 4-point Likert-type rating of 0 "not at all suitable for me", 1 "somewhat appropriate for me", 2 "usually suitable for me", and 3 "completely suitable for me". Cronbach Alpha value for each sub-dimension of the adapted scale; Anxiety (7 items) 0.80; It was found to be 0.81 for Depression (7 items) and 0.75 for Stress (7 items).
Measured: 4 months
Secondary outcomes (2)
Kidney Disease Quality of Life Scoring
The Kidney Disease Quality of Life Scale (KDQOL-SF) is a scale used to evaluate the well-being and function of individuals with kidney disease and undergoing dialysis treatment. The scale was developed by Hays et al. in the USA in 1994 (Hays et al., 1994). The validity and reliability study in our country was carried out by Yıldırım et al. in 2007.
Measured: 4 months
Cortisol level
All cortisol levels before and after laughter were measured in a fully automatic Roche Cobas 8000 device using the elecsys cortisol II kit, according to the electrochemiluminescence immunoassay method in the central laboratory of a State Hospital.
Measured: 4 months

Clinical summary

Therefore, this study was conducted to evaluate the blood cortisol levels, depression, anxiety, stress levels and quality of life of laughter therapy in hemodialysis patients.
