“…Thus, the survey contained 57 items. Based on the cross‐sectional study sample size calculation recommendation (Ni et al., 2010), the sample size was calculated according to the number of all items included in the survey multiplied by 10 times. Hence, we should collect 570 (57*10) questionnaires from nurses.…”

AimTo explore the mediating role of psychological capital between authentic leadership and innovative behaviour among Chinese nurses.DesignA cross‐sectional study.MethodsIn December 2021, online surveys were delivered among nurses from 37 hospitals in Anhui Province by convenience sampling approach. The data was collected using the Chinese version of the Authentic Leadership Questionnaire, Nurse Psychological Capital Questionnaire and Nurse Innovative Behaviour Scale. The structural equation model and bootstrap test examined the mediating role of psychological capital between authentic leadership and innovative behaviour.Results3495 Chinese nurses from 37 Anhui Province hospitals participated in this study. The mean item score of authentic leadership was 3.25 (SD 0.83), psychological capital was 4.85 (SD 0.89), and innovative behaviour was 2.82 (SD 0.84). Authentic leadership perceived by nurses, psychological capital, and innovative behaviour were statistically significant and positively correlated with each other (r = 0.524 ~ 0.806, p < 0.01). Psychological capital significantly mediated the association between authentic leadership and innovative behaviour (β = 0.449, p < 0.001), and its mediating effect accounted for 76.75% of the total effect.ConclusionResults suggest the importance of developing nurse managers' authentic leadership to foster nurses' psychological capital and innovation behaviour.

“…Hence, we should collect 570 (57*10) questionnaires from nurses. We estimate 20% of the completed surveys as invalid responses (Ni et al., 2010), which led to the minimum sample size required being 713 (570/[1–0.2]).…”

“…Exclusion criteria: (a) combined with severe cardiac, liver and renal dysfunction or other malignant tumours and (b) a history of serious mental illness or a family history of serious mental illness. Ping35 proposed that the sample size should be at least 5–10 times the independent variables. There were 16 variables in this study (13 general information questions, the recurrence risk perception of stroke scale, the PSS scale (PSSS) and the Health Behaviour Scale for patients with stroke (HBS-SP)).…”

ObjectivesTo examine whether patients who had a stroke with high recurrence risk perception would have healthier behaviour and to explore whether perceived social support would function as a mediator.DesignA cross-sectional study.SettingThe study was conducted in a public tertiary hospital in China.ParticipantsA total of 254 patients with stroke were invited to participate, and 250 patients with stroke completed questionnaires validly.Primary and secondary outcome measuresQuestionnaires were administered offline to collect data, consisting of four parts: general demographics and scales related to recurrence risk perception, perceived social support, and health behaviour. A path analysis and correlation analysis were used to analyse the data.ResultsOut of 250 patients with stroke, 78.4% had moderately low health behaviour. The majority (70.8%) of these patients were elderly. High recurrence risk perception and high perceived social support were significantly associated with better health behaviour (all p<0.001). Perceived social support mediated the relationship between recurrence risk perception and health behaviour after controlling for age, gender, education and monthly income in the regression model (95% CI 0.263 to 0.460) and the effect value was 0.360. It was also confirmed that perceived social support had the highest mediation effect with a proportion of mediation up to 59.31%.ConclusionsRecurrence risk perception and perceived social support were influential factors in promoting health behaviour. Moreover, the impact of recurrence risk perception on health behaviour was partially mediated by perceived social support. Therefore, to enhance the sustainability of health behaviour, it is crucial to inform patients with stroke about the risk of recurrence. Patients with more perception of recurrence risk can improve their recovery confidence and thus perceive more social support.

“…The inclusion criteria for the study were individuals who were: (a) aged 18–59 years; (b) diagnosed with ischemic or haemorrhagic stroke; (c) Mandarin speakers without aphasia; (d) capable of signing an informed consent form and willing to cooperate with the survey. Equation N = 4 Uα 2 S 2/ δ 2 was used to calculate the sample size (Ni et al., 2010). S = 0.44 was calculated from the presurvey, the allowable error δ was set to 0.1, and α was set to .05, so N = 4 × 1.96 2 × 0.44 2 /0.1 2 ≈ 297.…”

Accessible SummaryWhat is known about the subject? Loneliness is common among young and middle‐aged stroke survivors. It not only hinders the recovery of their neurological and physical functions but also increases the risk of stroke recurrence, disability, and even death. Improving the mental health of young and middle‐aged stroke survivors is of utmost importance. However, previous research has not yet investigated the impact of interpersonal sensitivity and resilience on the relationship between stigma and feelings of loneliness. What the paper adds to existing knowledge? This study confirms that stigma has a positive impact on loneliness among young and middle‐aged stroke survivors. Interpersonal sensitivity partially mediates the relationship between stigma and loneliness, and resilience plays a moderating role in the mediating mechanism. What are the implications for practice? Mental health nurses can formulate nursing interventions to reduce loneliness of young and middle‐aged stroke survivors with the goals of improving stigma, reducing interpersonal sensitivity and cultivating resilience. AbstractIntroductionPrevious studies have not explored the impact of interpersonal sensitivity and resilience on the relationship between stigma and loneliness. However, improving the resilience of young and middle‐aged stroke survivors and increasing their social participation is of great significance for reducing patients' loneliness of patients and promoting their physical and mental rehabilitation.AimsTo investigate the influence of stigma, interpersonal sensitivity and resilience on loneliness among young and middle‐aged stroke survivors.MethodsA cross‐sectional design was used to collect data. A total of 330 participants completed measures of stigma, resilience, interpersonal sensitivity and loneliness. The descriptive statistical approach, Pearson's correlation analysis and Hayes' PROCESS Macro Model 4 and 7 in regression analysis were used to analyse the available data.ResultsThe results revealed that young and middle‐aged stroke survivors' stigma, resilience, interpersonal sensitivity and loneliness were significantly correlated between every two variables, with coefficients ranging between −0.157 and 0.682. Interpersonal sensitivity played a partial mediating role in stigma and loneliness, accounting for 63.27% of the total effect; This process was moderated by resilience.DiscussionStigma positively predicts participants' loneliness. As a mediating mechanism with moderating, interpersonal sensitivity and resilience further explain how stigma affects loneliness.Implications for PracticeUnderstanding this mechanism is of guiding significance to reduce loneliness of young and middle‐aged stroke patients and promote their physical and mental rehabilitation.
