The main purpose of this study is to determine the effect of Roy adaptation model-based virtual reality glasses application on adaptation difficulties, life satisfaction, and psychological well-being in the elderly using a randomized controlled experimental method.

The hypotheses of the study are:

H1: The Roy adaptation model-based virtual reality glasses application has an effect on adaptation difficulties in the elderly.

H2: The Roy adaptation model-based virtual reality glasses application has an effect on life satisfaction in the elderly.

H3: The Roy adaptation model-based virtual reality glasses application has an effect on psychological well-being in the elderly.

In the 21st century, advances in science and technology have led to demographic changes, resulting in an increase in the elderly population. In this process, developments in the field of health such as increased preventive health services and early diagnosis and treatment of diseases played an important role. Aging is a natural process and can be defined as a decrease in an individual's physical and spiritual functions and an increase in external dependency. Adapting the elderly to this period supports psychological well-being by increasing functionality and life satisfaction. The Roy Adaptation Model aims for nurses to meet the needs of individuals to adapt, and this model can also be applied to the elderly. With technological advances, innovations such as virtual reality are used in the field of health and help improve the quality of life of the elderly. In the literature, studies examining the effects of Roy Adaptation Model and virtual reality glasses application on adaptation difficulties, life satisfaction and psychological well-being in the elderly are limited. This study aims to determine the effects of Roy Adaptation Model and virtual reality glasses application on adaptation difficulties, life satisfaction and psychological well-being in the elderly and to lay the foundation for evidence-based research. The thesis is a pre-posttest randomized controlled study with experimental and control groups. In the thesis study, data were collected as pre-post test from the elderly living in nursing homes using the Personal Information Form, Adaptation Difficulty Assessment Scale in the Elderly, Life Satisfaction Scale in the Elderly, and Psychological Well-Being Scale in the Elderly.In the thesis study, the experimental group was shown educational videos and nature videos with VR SHINECON 360 degree virtual reality glasses, based on the Roy adaptation model adaptation areas titles (physiological needs, self-concept area, role function area, interdependence area) twice a week for four weeks.

Inclusion Criteria:

• Those aged 60 and over
• Residents of Kocaeli nursing home
• Those who score 25 and above in the Standardized Mini Mental Test

Exclusion Criteria:

• Not wanting to participate in the research voluntarily
• Those who score 24 or below on the Standardized Mini Mental Test

Participants were assigned to groups using the "simple randomization method." Participants were not informed about which group they were in. Unique 2-group columns were created with the registration numbers of elderly individuals in nursing homes by using the Random Integer Generator method under the numbers subheading on the Random.org website. The researcher was blind to all conditions until participants started the computer program and the intervention began. Participants were also unaware of whether the group they were assigned to was an experimental or control group. Additionally, researchers who coded and analyzed the data were blinded to randomization and interventions.
