“…The exclusion criteria included: (1) disturbance of consciousness; (2) mental illness; and (3) the inability to care for oneself. According to the calculation principle of Kendal sample size, the sample should be larger than 10 times the number of estimated parameters (Castro Alves & Kendall, 2018). The number of free parameters to be estimated in this study was 21 and the minimum sample size required was 210.…”

This study aimed to investigate the common status of self-management in liver transplant recipients and to explore the mediating role of hope in the relationship between social support and self-management. Two hundred and ten liver transplant recipients from two tertiary hospitals were included. Questionnaires were used for general demographic information, the Perceived Social Support Scale, the Herth Hope Index, and the Self-Management Questionnaire for Liver Transplantation Recipients. Lifestyle management of liver transplant recipients was good, while the communication with physicians, cognitive symptom management, and exercise dimensions were less than satisfactory. Minimal assurance of family and education levels were significantly associated with self-management. Social support was positively correlated with self-management and hope ( r = .31, p < .01; r = .40, p < .01). Hope was positively correlated with self-management ( r = .39, p < .01). Additionally, the effect of social support on self-management was partially mediated (β = .17, p < .01) by hope. The proportion of mediation of hope was 40.09%. Therefore, well-designed interventions that boost both social support and hope may help improve self-management behavior in liver transplant recipients.

“…The sample size was estimated using the Kendall sample size estimation method ( 12 ), which recommends a sample size of 5 to 10 times the number of variables. Considering a 20% rate of invalid questionnaires, the required sample size was determined to be between 125 and 250 participants.…”

BackgroundNursing occupational fatigue has emerged as a critical issue affecting the safety and health of nurses. This phenomenon not only impairs nurses’ performance and mental well-being but also poses risks to patient safety and the quality of care provided. This study focuses on endoscopic nurses to explore the mediating role of positive coping styles between sleep quality and occupational fatigue, aiming to identify effective strategies to alleviate fatigue, thereby improving the work environment and enhancing healthcare quality.MethodsFrom July to August 2023, a cross-sectional design was used to select 258 endoscopy nurses from 25 top-three hospitals in 14 cities across 5 provinces in China. Data was collected through general information questionnaires, Fatigue assessment instrument, Pittsburgh sleep quality index, and Simple Coping Style Questionnaire. A structural equation model of sleep quality – positive coping style – occupational fatigue was constructed using Amos 26.0, and Bootstrap was employed to test the mediating effect.ResultsThe results showed that the mean scores of sleep quality, occupational fatigue, and positive coping style for endoscopy nurses were 8.89 ± 4.13, 17.73 ± 5.64, and 18.32 ± 10.46, respectively. Positive coping style were negatively correlated with sleep quality and occupational fatigue (p < 0.001). Positive coping style partially mediated the relationship between sleep quality and occupational fatigue, with a mediating effect value of 0.253, accounting for 42.10% of the total effect.ConclusionSleep quality can indirectly affect the level of occupational fatigue through positive coping style. Nursing managers should enhance nurses’ positive coping skills, improve nurses’ sleep quality, and reduce occupational fatigue among nurses.

“…In estimating the sample size, the primary reference is the sample estimation method of Castro and Kendall, which ensures that the sample size reaches at least 10–15 times the number of variables. 25 There were 15 variables in this study; considering the validity of the questionnaire during the survey process, another 10% enlarged the sample size, and 165-248 patients should be collected to meet the needs. A total of 250 questionnaires were distributed in this study since four patients had problematic answers, of which 246 were considered valid, resulting in a valid return rate of 98.4%.…”

Purpose To establish the relationship between medication literacy and medication beliefs among persons with type 2 diabetes mellitus (T2DM). Patients and methods A cross-sectional survey of 246 patients with T2DM was conducted between April and November 2022 at a tertiary hospital in Dongguan City, Guangdong Province, China. Subsequently, these patients were administered the General Information Questionnaire, the Chinese version of Medication Literacy Assessment Scale, and the Chinese version of Beliefs about Medicines Questionnaire-Specific via survey. Results The medication literacy score of patients with T2DM was 7.82±3.007, and the medication beliefs score was 2.26±4.011. The Pearson correlation analysis revealed a statistically significant but weakly positive correlation ( r = 0.271, P < 0.001) between medication literacy and beliefs among patients diagnosed with T2DM. However, there was no significant correlation found between medication literacy and necessity ( r = −0.021, P > 0.05), while a lowly negative correlation was observed between medication literacy and concerns ( r = −0.307, P < 0.001). Moreover, the multiple linear regression analysis indicated that medication literacy, age, education level, and duration of medication usage were all significant factors influencing patients’ medication beliefs (all P < 0.05). Together, these variables accounted for 15.3% of the total variance observed in the regression equation. Conclusion The study found a positive correlation between medication literacy and beliefs, and a negative correlation between medication literacy and concerns. These results indicate that enhancing medication literacy can improve medication adherence among individuals with T2DM by reducing concerns and strengthening medication beliefs.
