(W B Saunders Co-elsevier inc, 2023) Yildiz, Metin; Varol, Ela; Elkoca, Ayse; Yildirim, Mehmet Salih; Sarpdagi, Yakup
We conducted this study to determine the correlation between old age adaptation, aging in place, and depression in older adults. We carried out the descriptive correlational study with older adults (n:319) Agri Provincial Directorate of Health between October 2021 and April 2022. "SPSS 25 and Amos 23 programs" were used in the analysis of the data. Python 3.11.1, Microsoft Power BI programs were used for machine learning and graphical visualizations. In the study, it was determined that the model for the relationship between aging at a place level, adaptation difficulty in older adults level, and geriatric depression level was significant (F(2,316) = 37.002, p = 0.001). The aging in place level and the adaptation difficulty in older adults level explain 18.5% of the total variance of the level of geriatric depression. In the regression model, it was determined that the increase in the level of aging in place (t =-6.081, p < 0.001) and the decrease in the level of adaptation difficulty in older adults (t = 4.107, p < 0.001) of the participants caused a statistical decrease in the level of "Geriatric Depres-sion." It has been determined that adaptation difficulty in older adults has a moderator role in the relationship between geriatric depression level and aging in place level. In our data set, while the estimate of the presence of depression was 40 % with logistic regression analysis, it was 97 % with Random Forest. The study determined that as the level of aging in-place increased and the adaptation difficulty in older adults decreased, and depression decreased.
The Effect of Rumination and Elder Abuse Level on Successful Aging in Elderly Individuals: Analysis With a Machine Learning Approach
(Wiley, 2023) Yildiz, Metin; Varol, Ela; Yildirim, Mehmet Salih; Elkoca, Ayse; Sarpdagi, Yakup
Background: This study aimed to determine the effect of rumination and elder abuse levels on successful aging in elderly individuals. Methods: This descriptive-correlational study was conducted with older individuals (n = 297) in Agri, Turkey, between October 2021 and May 2022. SPSS-22 and R v.4.1.3 were used in the study. Analysis was done with machine learning and artificial neural networks. Results: In the study, the mean age of the older individuals was 67.49 +/- 3.04. Statistical estimates showed the regression model to be significant and usable, F(2,294) = 116.659, P = 0.001. Elder abuse and ruminative thought levels together explained 43.9% of the total variance (R-2 = 0.439) of successful aging. The regression model indicated that increases in both the elder abuse level (t = -3.672, P < 0.001) and the ruminative thought level (t = -12.771, P < 0.001) of participants caused a statistically significant decrease in the successful aging level. The combined elder abuse and ruminative thought levels had a greater effect on successful aging (Model 1: F = 45.321, Model 2: F = 116.659, R-2 Change = 0.309). The R-2 value of the Random Forest regression model was 0.529, showing that the independent variables could explain 52.92% of the variation in the dependent variable. According to the SHapley Additive exPlanation values, which show the contribution or importance of each variable in the estimation of the model, it was determined that the most important variables for estimating the Successful Aging Scale variable were ruminative thought style and elder abuse screening. Conclusions: Our study indicates that a decrease in the levels of rumination and elder abuse could lead to improvement in successful aging. Longitudinal studies on successful aging in older individuals are recommended.
Investigation the Relationship Between Xenophobic Attitude and Intercultural Sensitivity Level in Nurses
(W B Saunders Co-elsevier inc, 2024) Yildiz, Metin; Yildirim, Mehmet Salih; Elkoca, Ayse; Sarpdag, Yakup; Atay, Mehmet Emin; Dege, Go khan
Objective: The level of intercultural sensitivity is important for nurses to approach the individual's culture in care and treatment without prejudice. In this study, it was aimed to determine the effect of nurses' intercultural sensitivity level on xenophobic attitude. Methods: This quantitative cross-sectional study was conducted at Van Training and Research Hospital between January and June 2022. The Introductory Information Form, the Xenophobia Scale, and the Intercultural Sensitivity Scale were used to collect the research data. SPSS-25 package program and R programming language 4.1.3 are used. Results: This study was conducted with 235 nurses. According to the findings obtained in our study, the regression model determine the effect of intercultural sensitivity on xenophobia level was found to be F(1,233) = 69.857, p = 0.001, and 23.1 % (R2 = 0.231) of the variance in the dependent variable was explained by the independent variable. Intercultural sensitivity has a negative and significant effect on the level of xenophobia (beta = -0.480; t (233) = -8.358, p = 0.001). When comparing the performance of all variables with machine learning algorithms for the prediction model, the best performing algorithm was found to be Random Forest (RF). The contributions of these variables to the model were calculated with Shapley Additive Explanations (SHAP) values. The most important variables that should be included in the model to predict the xenophobia variable are the respect for cultural differences sub -dimension and intercultural sensitivity variables. Conclusion: It was determined that as the level of intercultural sensitivity of the nurses increased, their xenophobic attitudes decreased. Longitudinal studies on xenophobic attitude in nurses are recommended. It is recommended to make predictions with different machine learning models.

(Wiley, 2025) Sarpdagi, Yakup; Yigit, Muhammet Faruk; Aydin, Muhammet Ali; Yildirim, Mehmet Salih; Ciftci, Necmettin; Yildiz, Metin
Background: Spirituality and psychological well-being are important in shaping attitudes toward death. Objective: This study was conducted to determine the mediating role of psychological well-being in the effect of spirituality on attitudes toward death in the elderly. Method: This cross-sectional descriptive study was conducted in a province of Turkey between February 2024 and June 2024 with 467 individuals aged 65 years and older. The variables affecting attitudes toward death were identified by conducting mediation analysis and predictive analysis with a machine learning approach. Data were analyzed using SPSS 22.0, G*Power 3.1, R programming language 4.1.3 programs. Results: In our study, the effect of spirituality on psychological well-being was found to be positive and statistically significant (coefficient = 0.660, P < 0.001). The direct effect of spirituality on neutrality and approaching acceptance, sub-dimensions of attitude toward death, was significant (coefficient = 1.603, P < 0.001), and its indirect effect through psychological well-being was also significant (coefficient = 0.179, lower limit confidence interval (LLCI) = 0.085, upper limit CI (ULCI) = 0.309). The direct effect of spirituality on escape acceptance (coefficient = 0.571, P < 0.001), one of the attitudes toward death sub-dimensions, was significant, but the mediation effect of psychological well-being was not significant (LLCI = -0.049, ULCI = 0.0438). The direct effect of spirituality on fear and avoidance of death, one of the attitudes toward death sub-dimensions, was not statistically significant at the 95% confidence level (coefficient = 0.094, P = 0.433). The indirect effect of psychological well-being on fear and avoidance of death was negative and significant (coefficient = -0.136, LLCI = -0.233, ULCI = -0.031). Conclusion: In this study, as spirituality increases, attitudes toward death also increase positively. It was found that as spirituality increases, people tend to have a more positive acceptance and approach toward death. This study suggests that spirituality may influence emotional responses to death and shape attitudes toward death, particularly neutral acceptance and escape acceptance. As psychological well-being increases in the elderly, acceptance of death increases and fear of death decreases. In the study, prediction with different machine learning approaches is proposed. Longitudinal studies on attitudes toward death are recommended.
