Background This study was conducted to examine the effect of hope and psychological well-being on quality of life in elderly cancer patients using latent profile analysis (LPA). Method The study was conducted with 398 elderly cancer patients in Ataturk University Research in Turkey between September 2024 and January 2025. R programming language 4.1.3, G*Power 3.1 and SPSS-22 program were used in the analysis of the study. Results In our study, in the first stage of LPA analysis, BIC values were obtained by iterating each model and each class for 4 models and 9 classes. Since the lowest BIC value was found in the EEE model, the EEE model was considered as the appropriate model in the study and the class analysis was performed over this model. It is concluded that the best fitting class is the 2-class solution. As a result of LPA, class 1 has the lowest arithmetic mean in all indicators. According to the latent classes of the individuals in our study; it was found that the quality of life of individuals with Low Psychological Status was significantly lower than individuals with High Psychological Status (p < 0.05). Conclusion In our study, two classes were found as a result of LPA. According to the classes, it was found that the quality of life of individuals with low psychological status was lower than individuals with high psychological status. Increased hope and psychological well-being were found to improve quality of life in elderly cancer patients. Longitudinal studies on quality of life in elderly cancer patients are recommended.

Background Kinesiophobia and successful aging are key factors affecting quality of life in older adults; kinesiophobia, the fear of movement, can lead to reduced physical activity, while successful aging promotes overall well-being. Aim This study was conducted to examine the effect of kinesiophobia and successful aging on quality of life in the older adults. Method This descriptive cross-sectional study was conducted with 451 older adults living in Erzurum between July and November 2024. R programming language 4.1.3, G*Power 3.1 and SPSS-22 program were used in the analysis of the study. Results In the study, the level of kinesiophobia explained 8.4% of the total variance of the quality of life level (R2 = 0.084). It was determined that an increase in the level of kinesiophobia (t=-6.406, p < 0.001) caused a statistically significant decrease in the level of "quality of life". Kinesiophobia level and successful aging levels together explain 52.4% (R2 = 0.524) of the total variance in quality of life level. It was determined that the increase in the level of successful aging of the participants (t=-2.854, p < 0.001) caused a statistical increase in the level of "quality of life". The SHAP values of the variables in the best-performing model were examined. According to the graph, successful aging is identified as the most important variable in predicting the quality of life variable. It was found that the successful aging variable has an effect that is 4.917 units higher compared to other variables. Conclusion In this study, it was found that quality of life decreased with increasing kinesiophobia, whereas quality of life increased with increasing level of successful aging. Longitudinal studies on quality of life in the elderly are recommended.
