Quality of life is defined as functional abilities that include the ability to fulfill an individual social role, the degree and quality of social interaction, mental health, physical competence, somatic senses such as pain, and satisfaction with life. The World Health Organization (WHO) defined quality of life in 1947 as a decrease not only in disease, disorder or disability, but also in physical, mental and social well-being. Old age is one of the situations in which the quality of life decreases. It is reported that the poor social and financial situation of individuals, low educational level, gender, lack of physical movement, decreased daily life activity level, decreased mobility ability, fall anxiety, sleep problems and other conditions that cause disability are determinants of the quality of life. According to the results of Bloom et al.'s study, elderly people wake up at night due to health problems.

According to the literature, the sleep and life of pet therapy applied to elderly individuals living in a nursing home there have not been any studies examining the effect on quality. For this reason, it was aimed to conduct this study in order to determine the effect of pet therapy applied to elderly individuals living in a nursing home on sleep and quality of life.

The study was planned to be conducted in a randomized controlled manner in order to determine the effect of pet therapy applied for one hour twice a week for 6 weeks to elderly people living in a nursing home in Tokat province on sleep pattern and quality of life. In the study, gender, age group and the presence of chronic diseases were taken as equivalence criteria. Since conducting the study single-blind will increase the reliability of the study, the application of the scales was applied by another researcher/surveyor other than the main researcher.

The study was planned to be conducted in a randomized controlled manner in order to determine the effect of pet therapy applied for one hour twice a week for 6 weeks to elderly people living in a nursing home in Tokat province on sleep pattern and quality of life.

The universe of the research consists of 74 elderly elderly individuals who are located in a nursing home in Tokat province and meet the criteria for inclusion.

As a result of the calculations; the minimum sample volume that will provide the test power (1-β) = 0.95 was calculated as a total of 46 (23 interventions + 23 controls) people, and the net power of this study was determined as 0.952.

In the research, the data will be collected through the 'Elderly Person Introduction Form" CASP-19 Quality of Life Scale and PUKI sleep quality scale and Mini Mental Test (MMT). Since conducting the study double-blind will increase the reliability of the study, the application of the scales was applied by another researcher/surveyor other than the main researcher.

The Control Group Protocol:

The elderly in this group have not been given any treatment, they have received routine nursing home care and necessary treatments if any. The first evaluation of the elderly in the control group, 6.week and 10.the necessary measurements were made with the scales three times a week in total. The scales were collected by the questionnaire by face-to-face interview method.

Intervention Group Protocol:

After the data collection process of the control group was completed, the data collection process of the intervention group and pet therapy were applied. As a result of literature review; there is no clear duration for pet therapy and it was found that the average activity duration was 10-30 minutes, 4-12 weeks and 6-24 sessions. Based on this literature information; for this research, pet therapy pet therapy was applied for a total of 6 weeks and 12 sessions, 2 times a week for an average of 20 minutes for each elderly individual. End of therapy 6.week rating and 10.the scale was applied three times in total, including control measurement after a week of therapy. The scales applied by the animal therapy researcher were collected by the face-to-face interview method by the interviewer who did not know the groups.

In the evaluation of data, IBM SPSS Statistics 25.0 (IBM Corp. Released 2017. IBM SPSS Statistics for Windows, Version 25.0.Armonk, NY: IBM Corp.) the statistical package program was used. The normal distribution of the data of numerical variables was evaluated by Shapiro-Wilk normality test/Kruskal Wallis test and Q-Q graphs. Spearman correlation analysis was performed to determine the relationship between the dimensions. Dec. Statistically, a value of p≤0.05 was considered significant.
