The association between perfectionism and academic procrastination among undergraduate nursing students: The role of self-efficacy and resilience.

AIMS: This study aimed to investigate the associations between perfectionism and undergraduate nursing students' academic procrastination, the mediating effects of self-efficacy and the moderating role of resilience. DESIGN: A cross-sectional survey. METHODS: The survey was conducted from March to May 2022 with a sample of 587 undergraduate nursing students in two undergraduate universities in China. A descriptive statistical approach, Pearson's correlation analysis and the Hayes' PROCESS Macro model 4 and 14 were used to analyse the available data. RESULTS: Adaptive perfectionism and maladaptive perfectionism negatively and positively predicted academic procrastination in nursing undergraduates, respectively. Self-efficacy played a partially mediating role in the association between adaptive perfectionism and academic procrastination. Furthermore, resilience played a moderating role in the association between adaptive perfectionism and academic procrastination. CONCLUSIONS: Maladaptive perfectionism and low levels of resilience and self-efficacy may increase the risk of academic procrastination among nursing undergraduates. Nursing educators can take measures to decrease the risk of academic procrastination among nursing undergraduate students by guiding them to cultivate adaptive perfectionism tendencies and improve their self-efficacy and resilience. IMPACT: The findings of this study can be used to develop targeted coping and prevention measures for nursing educators to reduce the incidence of academic procrastination among nursing undergraduates. PATIENT OR PUBLIC CONTRIBUTION: Five hundred eighty-seven undergraduate nursing students from two undergraduate universities participated in the study and responded to questions on perfectionism and academic procrastination, etc.

The role of self-efficacy and psychological resilience on the relationship between perfectionism and learning motivation among undergraduate nursing students: A cross-sectional descriptive study.

BACKGROUND: People's high requirements for medical care and the difficult academic tasks associated with the nursing profession require nursing students to have stronger learning motivation. PURPOSE: This study aimed to investigate the effect of perfectionism on the learning motivation of undergraduate nursing students and to explore the mediating factors influencing these two variables. METHOD: A total of 1366 nursing students from four undergraduate universities in Henan Province, China, were surveyed from May to July 2022. We conducted Pearson's correlation analysis and a regression analysis using PROCESS Macro Model 6 to explore the relationships among perfectionism, efficacy, psychological resilience, and learning motivation. RESULTS: The results indicated that perfectionism affected undergraduate nursing students' learning motivation not only directly but also indirectly through self-efficacy and psychological resilience. CONCLUSION: The results of this study offer certain theoretical support and guidance for research and interventions pertaining to undergraduate nursing students' learning motivation.

Nurses' feeling trusted and knowledge hiding: The role of psychological safety, felt obligation and traditionality.

Knowledge hiding is one of the dilemmas of organizational knowledge management. For nurses, knowledge hiding behavior is not conducive to improving the quality and efficiency of their work and hinders the innovation of nursing services. Based on the social exchange theory, the current study constructed a moderated mediation model by taking psychological safety and felt obligation as mediating variables, and traditionality as moderating variable, and explored the mechanism of feeling trusted affecting knowledge hiding behavior. The empirical research based on 285 nurses from China shows that feeling trusted is negative correlate with knowledge hiding behavior; feeling trusted can negatively affect knowledge hiding by enhancing psychological safety and felt obligation; traditionality can positively moderate the relationship between feeling trusted and felt obligation, and feeling trusted has a stronger positive influence on felt obligation of highly traditional nurses; traditionality has no significant moderating effect between feeling trusted and psychological safety. Theoretically, this study supplements the influencing factors of knowledge hiding, examines the complex mechanism between feeling trusted and knowledge hiding and supplements the boundary conditions for feeling trusted to play its role from the perspective of individual characteristics (i.e., traditionality). From the perspective of practical implication, this study suggests that managers should pay attention to using trust strategies to enhance subordinates' psychological safety and felt obligation, especially for highly traditional nurses, thus reducing knowledge hiding.

The mediating effects of coping style and resilience on the relationship between parenting style and academic procrastination among Chinese undergraduate nursing students: a cross-sectional study.

BACKGROUND: How to kindle the learning enthusiasm of nursing students and reduce the incidence of academic procrastination is an important factor in reducing student attrition and improving the quality of nursing education. OBJECTIVES: To investigate the mediating role of coping style and resilience on the association between parenting styles and academic procrastination among nursing undergraduates. METHODS: A cross-sectional study of 683 nursing undergraduates was conducted in China from March to May 2022. Parenting styles, coping style, resilience, and academic procrastination were measured using questionnaires. Descriptive analysis, Pearson's correlation analysis and Hayes' PROCESS Macro in SPSS 25.0 were used to test the model. RESULTS: Positive parenting style had a significantly direct effect on academic procrastination and through three significantly indirect pathways: (1) through positive coping style (B = - 0.048, 95% CI: - 0.074 to - 0.025), accounting for 14.71% of the total effect; (2) through negative coping style (B = - 0.044, 95% CI: - 0.071 to - 0.021), accounting for 13.64% of the total effect; and (3) through resilience (B = - 0.074, 95% CI: - 0.107 to - 0.044), accounting for 22.82% of the total effect. Moreover, negative parenting style had a significantly direct effect on academic procrastination and through two significantly indirect pathways: (1) through negative coping style (B = 0.056, 95% CI: 0.032 to 0.086), accounting for 21.73% of the total effect, and (2) through resilience (B = 0.028, 95% CI: 0.004 to 0.055), accounting for 10.93% of the total effect. CONCLUSIONS: Intervention measures to reduce the academic procrastination of nursing undergraduates should include the evaluations of coping styles and resilience of nursing students and cultivation strategies to promote their positive coping styles and resilience.

The associations between smartphone addiction and self-esteem, self-control, and social support among Chinese adolescents: A meta-analysis.

Background: Smartphone addiction has become a social problem that affects the healthy growth of adolescents, and it is frequently reported to be correlated with self-esteem, self-control, and social support among adolescents. Methods: A meta-analysis was conducted by searching the PubMed, Web of Science, Embase, PsycINFO, PsycArticles, China National Knowledge Infrastructure (CNKI), WANFANG DATA, and Chongqing VIP Information Co., Ltd. (VIP) databases. Stata 16.0 was used to analyse the overall effect and test the moderating effect. Results: Fifty-six studies were included, involving a total of 42,300 participants. Adolescents' smartphone addiction had a moderately negative correlation with self-esteem (r = -0.25, 95% CI = -0.29 to -0.22, p < 0.001), a strong negative correlation with self-control (r = -0.48, 95% CI = -0.53 to -0.42, p < 0.001), and a weak negative correlation with social support (r = -0.16, 95% CI = -0.23 to -0.09, p < 0.001). Moderation analysis revealed that the correlation between adolescents' smartphone addiction and self-esteem was strongest when smartphone addiction was measured with the Mobile Phone Addiction Tendency Scale for College Students (MPATS; r = -0.38). The correlation between adolescents' smartphone addiction and self-control was strongest when self-control was measured with the Middle school students' Self-control Ability Questionnaire (MSAQ; r = -0.62). The effect of dissertations on smartphone addiction, self-control, and social support among adolescents was significantly larger than that of journal articles. The correlation between adolescents' smartphone addiction and social support was strongest when smartphone addiction was measured with the Mobile Phone Addiction Index (MPAI; r = -0.24). However, the correlations between adolescents' smartphone addiction and self-esteem, self-control, and social support were not affected by age or gender. Conclusion: There was a strong relationship between smartphone addiction and self-esteem, self-control, and social support among adolescents. In the future, longitudinal research should be carried out to better investigate the dynamic changes in therelationship between smartphone addiction and self-esteem, self-control, and social support.

Resilience and positive coping style affect the relationship between maladaptive perfectionism and academic procrastination among Chinese undergraduate nursing students.

Background: Previous studies have not investigated the role of resilience and coping style on the association between maladaptive perfectionism and academic procrastination among nursing undergraduates. However, how to mobilize the learning enthusiasm of nursing students and reduce the incidence of academic procrastination is an important factor to reduce nursing loss and improve nursing quality. Objectives: To investigate the influence of maladaptive perfectionism, resilience and coping style on academic procrastination among Chinese undergraduate nursing students. Methods: A cross-sectional study was conducted. A convenience sampling method was used to select 665 nursing undergraduates from March to May 2022 in China. Maladaptive perfectionism, coping style, resilience, and academic procrastination were measured using questionnaires. The descriptive analysis, Pearson's correlation analysis and the Hayes' PROCESS Macro in SPSS 25.0 were used to test the model. Results: The results showed that nursing undergraduates' maladaptive perfectionism, resilience, positive coping style and academic procrastination were significantly correlated between every two variables, with coefficients ranging between -0.290 and 0.584. In addition, resilience played a partial mediating role in maladaptive perfectionism and academic procrastination, accounting for 15.70% of the total effect; in the meantime, this process was moderated by positive coping style. Conclusion: Maladaptive perfectionism positively predicted nursing undergraduates' academic procrastination; as a mediating mechanism with moderating, resilience and positive coping style further explained how maladaptive perfectionism promoted the academic procrastination of nursing undergraduates. Understanding this mechanism is of great significance for nursing educators to reduce the risk of academic procrastination in nursing undergraduates.

Perceived Parenting Style and Subjective Well-Being among Chinese Nursing Undergraduates: The Role of Self-Efficacy and Gender.

The question of how to improve the subjective well-being (SWB) of nursing students is an important factor for reducing nursing loss and improving nursing quality. The current study aimed to investigate the influence of parenting style and self-efficacy (SE) on SWB among Chinese nursing undergraduates. The moderating role of gender between parenting style and SWB was also examined. Descriptive analysis, Pearson's correlation analysis, and the Hayes' PROCESS Macro Model 4 and Model 5 were used to analyze the available data. A total of 665 nursing undergraduates (Mage = 19.86, SD = 1.19) completed questionnaires. The results showed that PPS was positively correlated with SWB (r = 0.421, p < 0.01), while NPS was negatively correlated with SWB (r = -0.167, p < 0.01). Meanwhile, SE was positively correlated with PPS (r = 0.167, p < 0.01) and negatively correlated with NPS (r = -0.175, p < 0.01). In addition, SE was positively correlated with SWB (r = 0.273, p < 0.01) and played a partial mediating role in the association between parenting style and SWB. Furthermore, gender moderated the direct effect of parenting style on SWB. Specifically, compared with male nursing students, parenting style has a greater influence on the SWB of female nursing students. These findings can be used to develop targeted improvement strategies for nursing educators to improve SWB levels among nursing undergraduates.

A meta-analysis of the relationship between bullying and non-suicidal self-injury among children and adolescents.

Non-suicidal self-injury (NSSI) has attracted increasing attention due to its high detection rate, high risk and high repeatability. There is a need for the early identification of preventable occurrence factors, which is necessary to facilitate screening and intervention, especially to facilitate the early detection of high-risk individuals. This research aims to investigate the relationship between bullying behaviour and non-suicidal self-injury among children and adolescents by means of meta-analysis. The PubMed, Embase, Web of Science, SCOPUS, PsycINFO, CKNI and WAN FANG databases were searched from inception to 14 December 2021 for studies that explored the relationship between bullying behaviour and NSSI among children and adolescents. A total of 29 articles met the inclusion criteria of the meta-analysis, and 54 independent effect sizes were obtained, including 53,501 subjects. Victims [OR 2.46 (95% CI 2.14-2.83); p < 0.001], bullies [OR 2.12 (95% CI 1.37-3.27); p < 0.001], and bully-victims [OR: 2.98 (95% CI 1.85-4.82); p < 0.001] were more likely to have NSSI than uninvolved children or adolescents. In addition, analyses showed the absence of publication bias. In the victim group, the older the age was, the lower the risk of NSSI (z = - 3.74, p = 0.00). Gender does not play a moderating effect on the association between bullying behaviour and non-suicidal self-injury. The relationship between involvement in bullying and NSSI was demonstrated. By taking measures to prevent bullying, the incidence of NSSI in children and adolescents can be potentially reduced.

Effects of Genistein on Common Kidney Diseases.

Genistein is a naturally occurring phytoestrogen (soy or soybean products) that is classified as an isoflavone, and its structure is similar to that of endogenous estrogens; therefore, genistein can exert an estrogen-like effect via estrogen receptors. Additionally, genistein is a tyrosine kinase inhibitor, which enables it to block abnormal cell growth and proliferation signals through the inhibition of tyrosine kinase. Genistein is also an angiogenesis inhibitor and an antioxidant. Genistein has effects on kidney cells, some of the kidney's physiological functions, and a variety of kidney diseases. First, genistein exerts a protective effect on normal cells by reducing the inflammatory response, inhibiting apoptosis, inhibiting oxidative stress, inhibiting remodeling, etc., but after cell injury, the protective effect of genistein decreases or even has the opposite effect. Second, genistein can regulate renin intake to maintain blood pressure balance, regulate calcium uptake to regulate Ca2+ and Pi balances, and reduce vasodilation to promote diuresis. Third, genistein has beneficial effects on a variety of kidney diseases (including acute kidney disease, kidney cancer, and different chronic kidney diseases), such as reducing symptoms, delaying disease progression, and improving prognosis. Therefore, this paper reviews animal and human studies on the protective effects of genistein on the kidney in vivo and in vitro to provide a reference for clinical research in the future.

The Relationship Between Self-Esteem and Mobile Phone Addiction Among Mainland Chinese Adolescents: A Meta-Analysis.

In recent years, the problem of mobile phone addiction (MPA) has become increasingly serious among mainland Chinese adolescents. Studies have found that self-esteem may be related to MPA, but the conclusions are inconsistent. Consequently, this meta-analysis aims to explore the real relationship between self-esteem and MPA, and analyze the moderator variables. The relevant studies used in meta-analysis were obtained by searching China National Knowledge Infrastructure (CNKI), Wan Fang Data, Chongqing VIP Information Co., Ltd. (VIP), PubMed, Web of Science, Scopus, Medline and Embase. Then articles were screened and coded, and statistical analysis was carried out by Stata 16.0 software. A total of 45,765 participants from 64 articles were included in the research. Meta-analysis showed that there was a moderate negative correlation between self-esteem and MPA(r = -.25, 95%CI = -.29, -.21). Subgroup analysis and meta-regression analysis showed that the age and publication time can significantly moderate the relationship between self-esteem and MPA, but MPA measurement instrument, gender, region and publication type have no significant moderating effect. The current meta-analysis provided solid evidence that self-esteem was negatively correlated with MPA. Longitudinal studies are needed to clarify the causality between them, so as to make more specific practice and policy recommendations.

Correlations Between Social Support and Loneliness, Self-Esteem, and Resilience Among Left-Behind Children in Mainland China: A Meta-Analysis.

Background: Social support is frequently reported to be correlated with loneliness, self-esteem, and resilience among left-behind children in mainland China. However, to date, there is no consensus on the extent to which those factors are correlated with social support among left-behind children. We thus performed a meta-analysis to quantitatively synthesize the previous findings. Methods: Two investigators systematically and independently searched PubMed, EMBASE, Web of Science, PsycINFO, Wan Fang, Chinese National Knowledge Infrastructure (CNKI) and China Science Technology Journal Database (VIP) on January 9, 2022. Pooled Pearson's correlation coefficients between social support and loneliness, self-esteem, and resilience were calculated by Stata 16.0 software using random effects model. Results: Forty-seven studies involving a total of 30 212 left-behind children were identified. A large degree of negative correlation was found between social support and loneliness [summary r: -0.36 (95% CI: -0.42- -0.30), p < 0.001]. Large positive correlations were found between social support and self-esteem, and resilience [self-esteem: summary r: 0.33 (95% CI: 0.24-0.41), p < 0.001; resilience: summary r: 0.45 (95% CI: 0.38-0.50), p < 0.001]. The pooled correlations revealed some discrepancies when stratified by some moderators. Sensitivity analysis also revealed the robustness of the findings. The Egger regression and Duvall and Tweedle trim-and-fill procedure suggest the absence of publication bias. Conclusion: The current meta-analysis provided solid evidence that social support has a high degree of negative correlation with loneliness and a high degree of positive correlation with self-esteem and resilience among left-behind children in mainland China. This indicated that left-behind children with high levels of social support tend to have lower levels of loneliness and higher levels of self-esteem and resilience. More studies, especially large prospective studies, are warranted to verify our findings.

The correlation between mobile phone addiction and coping style among Chinese adolescents: a meta-analysis.

BACKGROUND: Mobile phone addiction has become a social problem that affects the healthy growth of adolescents, and it may be correlated with coping style. The aim of this study was to investigate the relationship between mobile phone addiction and coping style and the influencing factors for adolescents. METHODS: A meta-analysis was conducted by searching China National Knowledge Infrastructure (CNKI), WANFANG DATA and Chongqing VIP Information Co., Ltd. (VIP), PubMed, Web of Science, Embase, and PsycINFO. Stata 16.0 was used to analyse the overall effect and test the moderating effect. RESULTS: Thirty-three studies were included, involving a total of 20,349 subjects. There was no significant correlation between adolescents' mobile phone addiction and positive coping style (r = - 0.02, 95% CI = - 0.06 to 0.02, P > 0.05), but there was a moderate positive correlation between adolescents' mobile phone addiction and negative coping style (r = 0.31, 95% CI = 0.26 to 0.36, P < 0.001). The moderating effect analysis showed that the effect of dissertations on mobile phone addiction and positive coping style among adolescents was significantly larger than that of journal articles. The Smartphone Addiction Scale for College Students (SAS-C) showed the largest effect on mobile phone addiction and positive coping style among adolescents. The time of publication significantly positively moderated the relationship between mobile phone addiction and negative coping style among adolescents. The Simplified Coping Style Questionnaire (SCSQ) showed the largest effect on adolescents' mobile phone addiction and negative coping style. However, the correlation between adolescents' mobile phone addiction and coping style was not affected by age or gender. CONCLUSIONS: There was a close relationship between mobile phone addiction and coping style among adolescents. In the future, longitudinal research should be carried out to better investigate the dynamic changes in the relationship between mobile phone addiction and coping style.

Mechanochemistry of nucleosides, nucleotides and related materials.

The application of mechanical force to induce the formation and cleavage of covalent bonds is a rapidly developing field within organic chemistry which has particular value in reducing or eliminating solvent usage, enhancing reaction rates and also in enabling the preparation of products which are otherwise inaccessible under solution-phase conditions. Mechanochemistry has also found recent attention in materials chemistry and API formulation during which rearrangement of non-covalent interactions give rise to functional products. However, this has been known to nucleic acids science almost since its inception in the late nineteenth century when Miescher exploited grinding to facilitate disaggregation of DNA from tightly bound proteins through selective denaturation of the latter. Despite the wide application of ball milling to amino acid chemistry, there have been limited reports of mechanochemical transformations involving nucleoside or nucleotide substrates on preparative scales. A survey of these reactions is provided, the majority of which have used a mixer ball mill and display an almost universal requirement for liquid to be present within the grinding vessel. Mechanochemistry of charged nucleotide substrates, in particular, provides considerable benefits both in terms of efficiency (reducing total processing times from weeks to hours) and by minimising exposure to aqueous conditions, access to previously elusive materials. In the absence of large quantities of solvent and heating, side-reactions can be reduced or eliminated. The central contribution of mechanochemistry (and specifically, ball milling) to the isolation of biologically active materials derived from nuclei by grinding will also be outlined. Finally non-covalent associative processes involving nucleic acids and related materials using mechanochemistry will be described: specifically, solid solutions, cocrystals, polymorph transitions, carbon nanotube dissolution and inclusion complex formation.
