UNASSIGNED: In the medical field, effective time management by clinical nurses is crucial for enhancing the quality of patient care. However, in recent years, with increasing work pressure for clinical nurses, procrastination has become a prevalent issue. Many nurses use smartphones as a way to alleviate stress and manage emotions, but excessive smartphone use could exacerbate procrastination, thereby jeopardizing patient safety and healthcare quality. Therefore, understanding the current state of work procrastination among clinical nurses, its heterogeneity, and exploring the impact of smartphone addiction and demographic factors on different aspects of nurse procrastination hold significant importance for improving patient care quality.
UNASSIGNED: This study aims to explore the current state of work procrastination among clinical nurses and identify potential profile categories. It further analyzes the impact of mobile phone addiction and demographic factors on work procrastination among clinical nurses.
UNASSIGNED: Convenience sampling was employed to recruit participants from three tertiary hospitals in central China from October to November 2023. Surveys measuring nurses\' work procrastination and smartphone addiction were distributed and collected through online platforms. A total of 1,536 nurses participated in this study. Mplus 8.3 statistical software was used for latent profile analysis of clinical nurses\' work procrastination, and SPSS 26.0 software was utilized for chi-square tests, rank-sum tests, and multi-classification logistic regression analyses.
UNASSIGNED: The median total score for clinical nurses\' work procrastination was 21.00 (17.00, 28.00), and three subgroups were identified: low procrastination (66.93%), medium-low procrastination (20.66%), and medium-high procrastination (12.41%). Additionally, logistic regression analysis revealed that smartphone addiction and department atmosphere were common influencing factors for medium-low and medium-high work procrastination. Hospitals with stricter management and nurses holding the position of head nurse were more likely to belong to the low work procrastination group. Nurses with higher incomes or those holding intermediate titles were more prone to medium-low work procrastination, while those experiencing career advancement difficulties were more likely to exhibit medium-high work procrastination (p < 0.05).
UNASSIGNED: Clinical nurses\' work procrastination is generally at a medium-to-low level, with three subgroups identified: low procrastination, medium-low procrastination, and medium-high procrastination. Additionally, clinical nurses in surgical departments or those with intermediate titles exhibit higher levels of procrastination. Factors such as smartphone addiction, higher monthly income, tense departmental atmosphere, and unsuccessful career advancement are more likely to lead to work procrastination. Conversely, nurses in hospitals with strict management or those holding the position of head nurse exhibit lower levels of work procrastination. Therefore, nursing managers should pay close attention to the work procrastination behaviors of clinical nurses, actively monitor predictive factors among different groups, and provide psychological counseling and relevant training based on individual nurse circumstances. Additionally, it is also essential to focus on and improve departmental atmosphere and nurse smartphone addiction to enhance clinical nurses\' work efficiency and reduce work procrastination.

In recent years, sleep problems among college students have become increasingly prominent, especially in the context of the COVID-19 pandemic, and their sleep quality has deteriorated dramatically, severely affecting their physical and mental health. Numerous research studies have investigated the relationship between mindfulness and sleep quality; however, it is still unclear what psychological process underlies this relationship. In the current study, college students\' bed procrastination and self-control as mediating factors in the association between mindfulness and sleep quality were investigated. Using the convenience sampling method, 763 Chinese college students (mean age = 19.48 years, SD = 2.06) were recruited to complete self-reported questionnaires that included the Mindful Attention Awareness Scale, Self-Control Scale, Bed Procrastination Scale, and Sleep Quality Scale. All statistical analyses were performed using SPSS 23.0 software. Results showed that (a) mindfulness was positively associated with sleep quality; (b) both self-control and bed procrastination mediated the relationship between mindfulness and sleep quality, and (c) self-control and bed procrastination sequentially mediated the relationship between mindfulness and sleep quality. These findings collectively suggest a potential mechanism for how mindfulness influences sleep quality, providing a therapeutic target for mindfulness-based interventions aimed at helping college students improve sleep quality.

Objectives: Evidence linking chronic procrastination to a range of poor health outcomes and trajectories continues to build. Yet, much of this research has been conducted in academic contexts or in non-student samples. Despite theory indicating that high-stress contexts increase vulnerability for procrastination, the pathways linking chronic procrastination to health outcomes proposed by the procrastination-health model have not been examined in a high stress environment. Accordingly, we tested the contribution of procrastination to health in nurses and whether social support was a protective factor. Design: Pre-registered cross-sectional study using a random sample of nurses recruited from the membership of a regional nursing association, supplemented by nurses and nurse trainees recruited from online nursing associations, conferences and forums. Methods: Nurses and nurse trainees (N = 597) completed measures of chronic procrastination, stress, health behaviours, social support and self-rated health. Results: Chronic procrastination was associated with perceived stress, health behaviours, self-rated health and social support in the expected directions. Consistent with the procrastination-health model, structural equation modelling revealed significant indirect effects linking chronic procrastination to poor self-rated health through higher stress and fewer health behaviours. Contrary to our hypotheses, social support did not moderate these pathways. Conclusions: This study is the first to demonstrate the relevance of procrastination for health in high-stress, non-academic contexts and to find support for both the stress and behavioural pathways linking procrastination to poor health outcomes. Findings further highlight the importance of addressing chronic procrastination as a vulnerability factor for poor health in nurses.

UNASSIGNED: This study aimed to explore the relationship between physical activity and procrastination behavior among college students and the serial mediating roles of body self-esteem and overall self-esteem.
UNASSIGNED: A cross-sectional survey was conducted involving 1,018 college students. The Physical Activity Rating Scale, the College Students\' Physical Self-perception Profile, the Self-Esteem Scale, and the Chinese Procrastination Scale were utilized. Serial mediating effect analysis and Bootstrap analysis were applied to the data.
UNASSIGNED: (1) Individuals engaging in high levels of physical activity demonstrated significantly lower levels of procrastination behavior compared to those with moderate or low levels of physical activity (Partial η2 = 0.01, F = 2.762, p < 0.01). (2) Physical activity was positively correlated with body self-esteem (r = 0.37, p < 0.01) and overall self-esteem (r = 0.29, p < 0.01), and negatively correlated with procrastination behavior (r = -0.14, p < 0.01). body self-esteem was positively correlated with overall self-esteem (r = 0.11, p < 0.01) and negatively correlated with procrastination behavior (r = -0.13, p < 0.01). Overall self-esteem also showed a significant negative correlation with procrastination behavior (r = -0.26, p < 0.01). (3) Mediation effect analysis indicated that body self-esteem and overall self-esteem played partial mediating roles in the relationship between physical activity and procrastination behavior among college students. The mediating effects were composed of three pathways: \"Physical Activity → body self-esteem → Procrastination Behavior,\" \"Physical Activity → Overall Self-Esteem → Procrastination Behavior,\" and \"Physical Activity → body self-esteem → Overall Self-Esteem → Procrastination Behavior,\" with the effect sizes accounting for 27.70, 12.26, and 7.28% of the total effect, respectively.
UNASSIGNED: The findings of this study lead to several key conclusions regarding the relationship between physical activity, self-esteem, and procrastination behavior among college students. Firstly, engagement in moderate levels of physical activity is more effective in reducing procrastination behavior among college students. Secondly, participation in high volumes of physical activity is associated with increased levels of both body self-esteem and overall self-esteem. Lastly, physical activity not only directly impacts procrastination behavior but also indirectly influences it by enhancing body self-esteem and overall self-esteem, thereby further reducing the individual\'s level of procrastination. These conclusions suggest that physical activity plays a multifaceted role in mitigating procrastination behavior in college students. By promoting self-esteem, physical activity can foster a positive psychological state that is conducive to proactive behavior and academic success. The study\'s findings underscore the importance of integrating physical activity into college students\' daily routines as a strategy to combat procrastination and enhance self-esteem.

BACKGROUND: Previous research has revealed a negative association between social support and procrastination. However, few studies have investigated the mechanism underlying this relationship among vocational college students.
OBJECTIVE: Based on the social cognitive theory, this study was intended to investigate the multiple mediating effects of self-efficacy and resilience on the relationship between social support and procrastination among vocational college students.
METHODS: This study employed a cross-sectional design involving a sample of 1,379 students from a vocational college in China. Data were collected using the General Procrastination Scale, the Multidimensional Scale of Perceived Social Support, the General Self-Efficacy Scale, and the Resilience Scale-14. The PROCESS macro for SPSS was used to examine the multiple mediation model.
RESULTS: Our findings indicate significant negative correlations between social support, self-efficacy, resilience, and procrastination. The multiple mediation analysis showed that social support did not have a significant direct impact on procrastination. Instead, the relationship between social support and procrastination was fully mediated by self-efficacy (indirect effect: -0.017; 95% CI: -0.032, -0.004) and resilience (indirect effect: -0.047; 95% CI: -0.072, -0.025), and sequentially mediated by both factors (indirect effect: -0.013; 95% CI: -0.020, -0.007).
CONCLUSIONS: The results emphasise the importance of enhancing self-efficacy and resilience in initiatives aimed at preventing and intervening in case of procrastination among vocational college students. Additionally, strengthening social support may also be crucial to preventing or reducing procrastination among this population.

Studies have shown that maladaptive parenting styles, particularly parental psychological control may be an important risk factor for emotional problems in adolescence. However, the potential mechanisms behind this association are still not fully understood. To fill the research gap, this study investigated the relationship between parental psychological control and depression and anxiety among adolescents. It also explored the mediating effect of bedtime procrastination and the moderating effect of neuroticism through a moderated mediation analysis. A sample of 665 adolescents (331 girls) were recruited from two secondary schools in southern China. All participants completed standardized self-report questionnaires measuring the severity of parental psychological control, bedtime procrastination, depression, anxiety, and neuroticism. Data were analyzed using SPSS 25.0 and PROCESS macros. The results indicated that parental psychological control had a positive predictive effect on depression and anxiety among adolescents. Bedtime procrastination partially mediated the relationship between parental psychological control and depression, as well as parental psychological control and anxiety. Neuroticism was found to play a moderating role in the path from bedtime procrastination to depression and from bedtime procrastination to anxiety, with these effects being stronger for adolescents with higher levels of neuroticism. This study advances a deeper understanding of how and when or for whom parental psychological control is related to adolescents\' severe depression and anxiety. Our findings suggest that intervention programs or strategies aimed at reducing parental psychological control and assisting adolescents in establishing healthy sleep hygiene practices should be developed to decrease the risk of depression and anxiety in adolescents.

OBJECTIVE: Good sleep is one of the necessary conditions to ensure the normal performance of the physiological and psychological functions of college students. This study aimed to explore the relationship between mobile phone addiction and bedtime procrastination among Chinese college students and the mediating mechanisms of physical exercise and anxiety between the two, with a view to seek ways to prevent and intervene in college students\' sleep procrastination and improve their sleep quality.
METHODS: Using SPSS 29.0 analysis with Bootstrap\'s method, 3,800 first-year students, sophomores, and juniors were given the Mobile Phone Addiction Tendency Scale, Bedtime Procrastination Scale, Physical Activity Scale, and Anxiety Scale. The results of the analyses included mediation tests and effect analyses of anxiety and physical activity.
RESULTS: The correlation analysis revealed significant positive correlations between mobile phone addiction and bedtime procrastination (r = 0.149, p < 0.01) as well as anxiety (r = 0.497, p < 0.01). Additionally, there was a significant negative correlation between mobile phone addiction and physical activity (r = -0.447, p < 0.01). Physical activity was also found to have significant negative correlations with anxiety (r = -0.506, p < 0.01) and bedtime procrastination (r = -0.424, p < 0.01). Furthermore, anxiety showed a significant positive correlation with bedtime procrastination (r = 0.334, p < 0.01). Physical activity and anxiety acted as substantial mediators between mobile phone addiction and nighttime procrastination. Both mediators had considerable masking effects, with the mediating effect amounting to 50.3% and 25.1%, respectively. Physical exercise and anxiety played a chain mediating role between mobile phone addiction and bedtime procrastination, and the masking effect was also significant, with a mediating effect size of 13.4%.
CONCLUSIONS: This study reveals the special characteristics of the influencing factors and pathways of bedtime procrastination in this group of college students, providing targeted evidence for the prevention and intervention of bedtime procrastination in college students. It also has an important reference value for the effects of exercise and comprehensive intervention to improve bedtime procrastination and enhance the quality of sleep in college students.

UNASSIGNED: The current study investigated procrastination as a potential moderator of the association between cannabis use and college grade point average (GPA). Participants: 220 college students (ages 18 - 24; 71.8% female) in the Northwestern U.S. who were registered for classes in Fall 2021.
UNASSIGNED: Demographic questions, substance use history, the Beck Anxiety Inventory, the Center for Epidemiologic Studies Depression scale, and a Procrastination scale were completed via an online survey. Official term and cumulative GPA records were also collected.
UNASSIGNED: A regression model indicated that procrastination moderated the association between lifetime cannabis use and cumulative college GPA, whereas this moderation was not present when examining the relationship between past month cannabis use and term GPA.
UNASSIGNED: The current study identifies a putatively modifiable factor that may be related to academic performance for students who use cannabis. These results may help inform future interventions designed to help students using cannabis succeed academically.

The issue of academic procrastination is highly prevalent among university students. It not only has a deterimental effect on students\' academic performance but also poses a risk to their physical and mental well-being. Anxiety, as a negative emotion, has attracted researchers\' attention in relation to academic procrastination. Research indicates a correlation between state anxiety and academic procrastination, but the underlying mechanisms that drive this association remain unclear. When individuals experience ego-depletion, it can lead to psychological exhaustion, subsequently leading to procrastination. Gender role conceptions, shaped by sociocultural and psychological mechanisms, have profound implications on individuals\' cognition, emotions, and behaviors. This study primarily aims to explore the relationship between state anxiety and academic procrastination among university students, with a particularly focus on the mediating role of ego-depletion and the moderating role of gender. A survey using the State Anxiety Scale, Ego-Depletion Scale, and Irrational Procrastination Scale was administered to 3370 undergraduates. State anxiety shows positive correlations with ego depletion and academic procrastination (r = 0.665, p < 0.01; r = 0.491, p < 0.01), while ego depletion is also positively linked to academic procrastination (r = 0.500, p < 0.01). State anxiety serves as a positive predictor of academic procrastination, with a confidence interval of 95% [0.626, 0.696]; additionally, ego depletion partially mediates the relationship between state anxiety and academic procrastination, with a confidence interval of 95% [0.168, 0.251]. Gender acts as a moderator in directly predicting the impact of state anxiety on academic procrastination and in the latter stage of mediating the effect of ego depletion. State anxiety can significantly and positively predict academic procrastination among university students. Ego-depletion partially mediates the relationship between state anxiety and academic procrastination. The direct predictive effect of state anxiety on academic procrastination, as well as the mediating role of ego-depletion, is moderated by gender. This provides educators and university students themselves with reference for addressing the issue of academic procrastination.

BACKGROUND: This study explores the intricate web of symptoms experienced by academically gifted high school students, focusing on procrastination, rumination, perfectionism, and cognitive flexibility. The well-being of these gifted adolescents remains a pivotal concern, and understanding the dynamics of these symptoms is vital.
METHODS: A diverse sample of 207 academically gifted high school students from Mashhad, Iran, participated in this study. Using convenience sampling, participants from grades 10, 11, and 12 were included, with detailed assessments conducted through questionnaires measuring the mentioned symptoms.
RESULTS: Our network analysis uncovers compelling insights into the interplay of these symptoms: Procrastination, though moderately central, exerts significant influence within the network, underscoring its relevance. Cognitive flexibility, while centrally positioned, curiously exhibits a negative influence, potentially serving as a protective factor. Negative perfectionism emerges as the keystone symptom, with both high centrality and a positive influence. Rumination displays substantial centrality and a positive influence, indicating its role in symptom exacerbation. Positive perfectionism, moderately central, lacks direct influence on other symptoms.
CONCLUSIONS: This network analysis provides a nuanced understanding of the relationships among procrastination, rumination, perfectionism, and cognitive flexibility in academically gifted adolescents. Negative perfectionism and cognitive flexibility emerge as critical factors deserving attention in interventions aimed at enhancing the well-being of this unique group. Further research should explore causal relationships to refine targeted interventions.
