Relationships of coping styles and psychological distress among patients with insomnia disorder

Prospective associations between heterogeneous sleep profiles and depressive symptoms in adolescents: The mediating role of coping styles

INTRODUCTION

Extant literature has linked sleep disturbance to depressive symptoms. However, the coexistence of naturally occurring sleep profiles among adolescents and the prospective associations between sleep profiles and depressive symptoms remain poorly understood. This study aims to uncover sleep patterns in Chinese adolescents based on a comprehensive set of sleep features (e.g., latency, daytime dysfunction, etc.) derived from the Pittsburg Sleep Quality Index (PSQI) and investigate the relationship between these profiles and subsequent depressive symptoms mediated by positive and negative coping styles.

METHODS

Five thousand five hundred five adolescents from Shandong province, China, enrolled (Mage = 16.83 years; 49.9% girls) in a two-wave longitudinal study (T1 in August 2023; T2 in February 2024). Latent class analysis (LCA) was conducted to identify adolescent sleep patterns. Mediation and sensitivity analyses were used to examine prospective associations between sleep patterns, coping styles, and depressive symptoms.

RESULTS

Four qualitatively distinct sleep profiles emerged: Healthy Sleepers (18.9%), Latency but Functioning Sleepers (13.6%), Efficient but Dysfunctional Sleepers (57.5%), and Medicated Maladaptive Sleepers (10.0%). Using the Healthy Sleepers as a reference group, Latency but Functional Sleepers, Efficient but Dysfunctional Sleepers, and Medicated Maladaptive Sleepers all predicted subsequent depressive symptoms through positive coping styles rather than negative coping styles. The relative indirect effects were 0.19, 0.19, and 0.32, respectively.

CONCLUSIONS

The study underscored that adolescents exhibit distinct sleep patterns, and specific sleep profiles may be prospectively associated with depressive symptoms mediated by positive coping styles.

Childhood maltreatment predicts poor sleep quality in Chinese adults: The influence of coping style tendencies

BACKGROUND

This longitudinal study assessed the prospective link between childhood maltreatment and sleep quality in adulthood, with a specific focus on examining whether different coping style tendencies influence these associations.

METHODS

The baseline sample included 1600 adult participants, with 1140 participants successfully followed up 5 years later. The key variables were measured using the Childhood Trauma Questionnaire (CTQ), Simplified Coping Style Questionnaire (SCSQ), and Pittsburgh Sleep Quality Index (PSQI). Generalized linear mixed models were employed to estimate unstandardized β estimates and 95 % confidence intervals (95%CIs). Structural equation modeling was used to test the mediation model.

RESULTS

Individuals reported childhood maltreatment at baseline were at an increased risk for sleep disturbances at follow-up. Childhood maltreatment negatively predicted the baseline coping style tendency (β = -0.29, P < 0.001), the baseline coping style tendencies negatively predicted the follow-up sleep quality (β = -0.10, P < 0.001), and childhood maltreatment positively predicted the follow-up sleep quality (β = 0.42, P < 0.01). The mediating effect of baseline coping style tendencies between childhood maltreatment and the follow-up sleep quality was significant, with an effect value of 0.03.

LIMITATIONS

First, the sample was from a single province (Shandong), which limits the generalizability of the findings. Second, recall bias was unavoidable in this adult sample study.

CONCLUSIONS

Developing positive coping strategies is an important way to reduce the risk of sleep problems in adults with a history of childhood maltreatment.

Coping style as a predictor of anxiety in relatives of patients with mental illness-a single-center study

BACKGROUND

Relatives of patients with mental illnesses such as schizophrenia and depression experience significant levels of anxiety. Accurately predicting their anxiety levels is crucial for the development of effective anti-anxiety interventions aimed at mitigating associated adverse outcomes.

METHODS

In this cross-sectional study, 238 relatives of patients with mental illness were recruited, and their responses were collected using the generalised anxiety disorder-7 (GAD-7) and simplified coping style questionnaire (SCSQ) scales. One-way analysis of variance and t-test were used to assess the mean scores of GAD-7 and SCSQ among relatives with varying characteristics. Pearson's correlations were used to examine the correlation between anxiety levels and coping style. Multi-level regression analyses were used to identify the impact of the independent variables on anxiety.

RESULTS

Among all relatives of patients with mental illness who participated in this survey, 238 completed the questionnaire. Females exhibited a higher mean GAD-7 score (9.72 ± 0.25) compared to males. Among participants aged 18-25 years, the GAD-7 (8.12 ± 0.17) score was the highest. Additionally, relatives of patients experiencing their first episode or with a disease duration of < 1 year, as well as relatives of patients with schizophrenia and depression, displayed higher GAD-7 scores. Correlation analysis revealed a positive correlation between anxiety and SCSQ (negative coping styles) (r = 0.476, p < 0.01). Multi-level regression analyses demonstrated that demographic variables (R2 = 0.474, F = 21.402, p < 0.01) and SCSQ (R2 change = 0.638, F = 37.526, p < 0.01) were significantly and positively associated with anxiety among relatives of patients with mental illness.

CONCLUSIONS

Most relatives of patients with mental illness experience varying levels of anxiety, which are influenced by their coping styles.

The weight of care: exploring the challenges faced by primary caregivers of children with traumatic brain injuries

Background

Traumatic brain injury (TBI) is a leading cause of death and disability in children, yet the full impact on their primary caregivers remains largely uncharted. This study seeks to delineate the current scope of the caregiving burden and to identify the key determinants that shape it, aiming to enhance clinical interventions and caregiving approaches.

Methods

We conducted a comprehensive survey of primary caregivers of pediatric TBI patients admitted to a top-tier children's hospital in China, spanning the period from January 15 to November 15, 2023. The Zarit Burden Interview (ZBI) served as the primary tool for gauging the level of caregiver burden, while the Simplified Coping Style Questionnaire (SCSQ) provided insights into their coping strategies.

Results

Our survey encompassed 284 primary caregivers of TBI children. The average ZBI score for this cohort was 40.57±10.41, indicating a considerable burden. Correlational analysis uncovered robust links between the burden of caregivers and several pivotal factors: the severity of TBI (r=0.496), intensive care unit (ICU) stay (r=0.525), monthly household income (r=0.604), and reliance on negative coping mechanisms (r=0.493), all of which were statistically significant (P<0.05). Further, a multiple linear regression analysis affirmed that the severity of TBI, ICU admissions, monthly income, and negative coping styles were independent predictors of caregiver burden (P<0.05).

Conclusions

The findings underscore the substantial burden shouldered by primary caregivers of TBI children. It is imperative to direct targeted support towards caregivers from economically disadvantaged backgrounds and those who tend to adopt negative coping strategies, to alleviate their burden.

The relationship between anxiety and depression in adolescent depression patients: The mediating effect of hope level and coping modes

Background

Adolescents diagnosed with depression are particularly susceptible to anxiety and depressive symptoms, this vulnerability often diminishes their future expectations and overall outlook on life. The objective of this research was to scrutinize the associated risk factors of adolescent depression and delineated the interplay between anxiety and depressive symptoms. Concurrently, it sought to ascertain the latent mediating effects of hope levels and coping strategies within this framework.

Methods

A mixed-methods research approach was employed. For the qualitative component, 18 adolescents with depression were interviewed following a semi-structured interview guide, with sessions audio-recorded. The data were subsequently transcribed and subjected to thematic content analysis. In the quantitative phase, a cross-sectional online survey was administered to 210 adolescents diagnosed with depression using Questionnaire Star, with data analysis performed using SPSS25.0 and AMOS 24.0.

Results

The qualitative analysis identified three major themes and nine categories as key risk factors influencing the onset of adolescent depression. Three major themes were generated: school factors, family factors, and other factors. Nine categories were generated: heavy academic load, strained peer, and teacher-student relationships; unstable family structures, internal familial conflicts, and high parental expectations; a strong sense of social isolation, insufficient sexual education, and prevalent suicidal ideation or attempts. A nurturing and supportive school environment significantly bolsters adolescents' sense of hope and coping abilities, while a warm and encouraging family setting effectively mitigates psychological stress. Conversely, heightened loneliness and the onset of suicidal ideation are frequently linked to diminished hope and the adoption of maladaptive coping strategies. Hence, to comprehensively understand the intricate interplay of these factors, this study concentrated on the levels of hope and coping mechanisms, investigating their potential mediating role in adolescent anxiety and depression. Quantitative analysis revealed a positive correlation between anxiety and depression (r = 0.767, p＜0.01). Additionally, it was found that hope levels and coping strategies mediated the relationship between anxiety and depressive symptoms (β = -0.24-0.84 = 0.20, p < 0.001; β = 0.19-0.51 = -0.10, p < 0.01), with the mediating influence of hope levels being more significant than that of coping strategies.

Conclusion

Enhancing hope levels and fostering positive coping strategies are instrumental in aiding adolescents with depression to alleviate their anxiety and depressive symptoms. Moreover, this study underscored the importance of focusing on adolescents' mental health and providing them with emotional support, thereby increasing their hope levels and encouraging the adoption of positive coping mechanisms to effectively address their challenges.

Mediated relationships between coping style and social support on the quality of life of disabled older adults

OBJECTIVE

This study aimed to explore the relationship between coping styles, social support and quality of life among disabled older adults and to examine the mediating role of coping styles in the relationship between social support and quality of life.

METHODS

Using a purposive sampling method, three investigators conducted a face-to-face questionnaire survey of eligible participants in the geriatric department of a tertiary care hospital in one of the largest cities in southern China between August 2021 and March 2022. A total of 187 questionnaires were collected, of which 176 were valid, with an effective response rate of 94.1%.

RESULTS

Social support and positive coping were positively related to disabled older adults' quality of life, while negative coping was negatively related to both social support and disabled older adults' quality of life. According to the mediating effect analysis after covariate adjustment, positive coping completely mediated the relationship between social support and older adults' quality of life (p < 0.01), with the mediating effect size accounting for 76.9% of the total effect. Negative coping had some mediating effect on the relationship between social support and older adults' quality of life (p < 0.01), with the mediating effect size accounting for 13.0% of the total effect.

CONCLUSION

The quality of life of disabled older adults is low, which is closely related to their social support and coping styles. Therefore, it is important to recognize and emphasize the key role that social support systems play in improving the quality of life of this population, broaden their access to social support and guide them to adopt positive coping styles.

The Mediating Effect of Coping Style in the Relationship Between Sleep Quality and Perceived Cognitive Impairment Among Breast Cancer Patients: A Cross-sectional Study

BACKGROUND

Perceived cognitive impairment is a significant symptom experienced by breast cancer patients and may be affected by sleep quality. Coping styles have potential relevancies with both sleep quality and perceived cognitive impairment. However, the empirical evidence supporting their association among breast cancer patients is limited.

OBJECTIVE

This study explored the associations between sleep quality, coping styles, and perceived cognitive impairment and tested the mediating role of coping styles in breast cancer patients.

METHODS

A total of 294 breast cancer patients were included in this cross-sectional study. Patients were assessed using the Pittsburgh Sleep Index Scale, the Simplified Coping Styles Questionnaire, and the Functional Assessment of Cancer Therapy-Cognitive Functioning (Version 3) Scale. The data were analyzed using SPSS and Process macros.

RESULTS

The direct effect of sleep quality on reported cognitive impairment was significant (β = -0.245, P < .001). Furthermore, sleep quality was found to have a significant indirect effect on perceived cognitive impairment through positive coping style (β = -0.026, P < .05) and negative coping style (β = -0.131, P < .05).

CONCLUSIONS

Our research suggests that sleep quality has both a direct effect on perceived cognitive impairment and an indirect effect through positive and negative coping styles in breast cancer patients. Moreover, negative coping style had a more pronounced mediating effect than positive coping style.

IMPLICATIONS FOR PRACTICE

Clinical medical staff could reduce the perceived cognitive impairment of breast cancer patients by improving their sleep quality and encouraging them to adopt a more positive coping style.

The relationship between childhood adversity and sleep quality among rural older adults in China: the mediating role of anxiety and negative coping

BACKGROUND

Studies have revealed the effects of childhood adversity, anxiety, and negative coping on sleep quality in older adults, but few studies have focused on the association between childhood adversity and sleep quality in rural older adults and the potential mechanisms of this influence. In this study, we aim to evaluate sleep quality in rural older adults, analyze the impact of adverse early experiences on their sleep quality, and explore whether anxiety and negative coping mediate this relationship.

METHODS

Data were derived from a large cross-sectional study conducted in Deyang City, China, which recruited 6,318 people aged 65 years and older. After excluding non-agricultural household registration and lack of key information, a total of 3,873 rural older adults were included in the analysis. Structural equation modelling (SEM) was used to analyze the relationship between childhood adversity and sleep quality, and the mediating role of anxiety and negative coping.

RESULTS

Approximately 48.15% of rural older adults had poor sleep quality, and older adults who were women, less educated, widowed, or living alone or had chronic illnesses had poorer sleep quality. Through structural equation model fitting, the total effect value of childhood adversity on sleep quality was 0.208 (95% CI: 0.146, 0.270), with a direct effect value of 0.066 (95% CI: 0.006, 0.130), accounting for 31.73% of the total effect; the total indirect effect value was 0.142 (95% CI: 0.119, 0.170), accounting for 68.27% of the total effect. The mediating effects of childhood adversity on sleep quality through anxiety and negative coping were significant, with effect values of 0.096 (95% CI: 0.078, 0.119) and 0.024 (95% CI: 0.014, 0.037), respectively. The chain mediating effect of anxiety and negative coping between childhood adversity and sleep quality was also significant, with an effect value of 0.022 (95% CI: 0.017, 0.028).

CONCLUSIONS

Anxiety and negative coping were important mediating factors for rural older adult's childhood adversity and sleep quality. This suggests that managing anxiety and negative coping in older adults may mitigate the negative effects of childhood adversity on sleep quality.

Comparison between problematic use of social media and YouTube to insomnia among Iranian adolescents: A mediating role of psychological distress

Objective

Problematic use of the internet has been linked to emotional and sleep concerns, although relationships with specific types of internet use are less well understood. YouTube, as an online platform with video-watching features, may attract individuals to spend considerable time, for those experiencing problematic use be termed problematic use of social media (PUSM) or problematic use of YouTube (PUY). Therefore, the present study investigated relationships between PUSM/PUY, psychological distress, and insomnia among the Iranian adolescents.

Methods

An online survey comprising Bergen Social Media Addiction Scale, YouTube Addiction Scale, Depression, Anxiety, Stress-21 Scale, and Insomnia Severity Index recruited 1352 participants.

Results

Results of Hayes' Process Macro showed significant correlations between the two types of problematic use and insomnia, with psychological distress as a mediator (unstandardized coefficient = 0.096 and 0.100).

Conclusion

The findings implied the effect of psychological distress in mediating the relationships of PUSM and PUY to insomnia.

The association between metacognition, coping style and fear of cancer recurrence among postmastectomy patients: A cross sectional study

PURPOSE

To investigate the incidence of fear of cancer recurrence (FCR) in Chinese postmastectomy patients and explore the relationships between metacognition, coping style, and FCR on the basis of the self-regulating executive function model.

METHODS

A total of 480 postmastectomy patients from two tertiary comprehensive hospitals in Xi'an were enrolled from March 2021 to November 2021. The participants completed demographic information, the Metacognitions Questionnaire-30 (MCQ-30), Positive Metacognitions and Positive Meta-Emotions Questionnaire (PMCEQ), Simplified Copying Style Questionnaire (SCSQ), and Fear of Cancer Recurrence Inventory Short Form (FCRI-SF).

RESULTS

34.2% of the respondents had scores indicating a clinical level of FCR (FCRI-SF≥13). FCR had a positive correlation with maladaptive metacognition and negative coping style (P < 0.01), while adaptive metacognition and positive coping style were negatively correlated (P < 0.01). Besides, maladaptive metacognition had both direct and indirect effects on FCR, with the indirect effect primarily mediated by negative coping style (total effect, 0.430). Adaptive metacognition had both direct and indirect effects on FCR, with the indirect effect primarily mediated by positive coping style (total effect,﹣0.302).

CONCLUSION

FCR was a common phenomenon in postmastectomy patients and moderate in most patients. In addition, both metacognition and coping style had a direct and indirect association with the occurrence and development of FCR. Moreover, adaptive metacognition and maladaptive metacognition had different mechanisms on FCR in patients with breast cancer.

Spouses' coping with stress during the COVID-19 pandemic: is there a difference between male and female attitudes?

This descriptive study was conducted to determine the stress-coping status of spouses and the difference between male and female attitudes during the pandemic period. We collected data with the Personal Information Form and the Scale for Coping with Family Stressors from 533 participants. The mean age of women and men was 36.04 ± 10.04 and 37.13 ± 11.56, respectively. A significant difference in verbalizing with others, work - family segmentation, cognitive restructuring, changing behaviors, emotional disclosure, exercise, and spending more time with family was found between women and men (p < .05). A significant difference was also observed in coping mechanisms with family stressors between women and men, and thus, gender affects their coping attitudes. During crises such as pandemics, the community should be aware of the availability of mental health professionals, and spouses should also use effective coping methods with family stress at regular intervals.

A study on different types of moral courage and coping styles of clinical nurses: based on potential profile analysis

BACKGROUND

In professional ethics-related events, there are various unpleasant and complex ethical issues that require strong moral courage. Our aim is to identify and describe the potential categories of moral courage among nurses and to clarify the coping styles of nurses under different categories.

METHOD

A cross-sectional study was conducted using three data collection tools: a self-designed general information questionnaire, a Chinese version of the Moral Courage Scale, and a Trait Coping Style Questionnaire. Three hundred fourteen nurses from a tertiary hospital in Heilongjiang Province, China, were analysed using potential profile analysis, descriptive analysis, and Mann-Whitney U test data.

RESULT

The latent profile analysis (LPA) results indicate that the two-profile model is the most suitable and supports the existence of two different moral courage profiles: the low moral courage group (60.51%) and the high moral courage group (39.49%), with a high relative entropy value (0.922). The results point to a good profile solution, and there are significant differences between the two profiles. The Mann-Whitney U-test results showed that the positive coping scores of the high moral courage group were significantly higher than those of the low moral courage group, and the negative coping scores of the high moral courage group were significantly lower than those of the low moral courage group.

CONCLUSION

Our results reveal the heterogeneity of moral courage in the nurse sample and indicate that nurses in the high moral courage group tend to choose positive coping styles, while nurses in the low moral courage group are more likely to develop negative coping emotions. This provides important significance and reference value for nursing managers, who can propose customised management plans based on the types of moral courage of the nursing community and the coping styles under different categories.

Pain experience of lung cancer patients during home recovery after surgery: A qualitative descriptive study

BACKGROUND

Patients with lung cancer surgery often suffer pain after discharge. However, there is limited evidence to describe the pain experience from the qualitative investigation. This study was designed to describe the pain experience of lung cancer patients during home recovery after surgery and to provide evidence for developing pain management strategies.

METHODS

This qualitative descriptive study recruited 35 patients who had received lung resection and were discharged by purposive sampling from May to July 2022. Mobile phone interviews were conducted to collect views on patients' pain experience after discharge. The interviews were audio-recorded and converted verbatim into standard text, and the data were iteratively thematic analyzed.

RESULTS

A thematic framework was identified for three themes: perception and impact of pain, coping styles for pain, and unmet needs for pain. Whether short or long-term after discharge, patients complain that they suffer from different degrees and types of pain, causing them a "double burden" physically and mentally. The lack of knowledge about pain may lead them to adopt very different coping styles and desire professional continuous pain management.

CONCLUSIONS

This study may help clarify the status of pain problems that patients face after lung cancer surgery and provides multiple dimensions of pain assessment and management objectives for quantitative research. We call on medical staff to pay attention to patients' perspectives and related needs after discharge and formulate targeted management strategies to reduce pain and improve their quality of life.

The association between psychosocial factors, protective factors, and its associated triggers with psychological distress among Bolivian adolescents

The purpose of this study is to investigate the association between psychosocial factors, protective factors, and its associated triggers with psychological distress among Bolivian adolescents. This cross-sectional study was conducted by investigating the 2018 Bolivia global school-based student health survey (GSHS). The total number of students who participated in this survey was 7931, and the final sample was 7377. The mean age of the participants was 15.3 years (SD = 1.4). Psychological distress was assessed with a 2-item screener (loneliness and worry induced sleep disturbance). In all 22.3% of participants reported experiencing psychological distress, with 18.1% among adolescent males and 26.2% among adolescent females. In adjusted logistic regression analysis (AOR, 95% CI), there are two significant directions of association. One is the negative association, such as parental involvement as a protective factor. School adolescents who had more parental involvement were less likely to experience psychological distress. Parents understand problems or worries (0.64, 0.54-0.75, p < .001) and parents disregard privacy (0.69, 0.58-0.82, p < .001). On the other hand, many psycho-social factors are significantly positively associated with psychological distress. School adolescents who experience more psychosocial factors are more likely to experience psychological distress. Physical assault in the previous year (1.83, 1.59-2.11, p < .001), being bullied at school (1.27, 1.07-1.52, p < .01), being bullied outside of school (1.36, 1.15-1.61, p < .001), and being cyberbullied (1.60, 1.37-1.88, p < .001), were all significantly associated with psychological distress. Healthy relationships in a family, and interventions to reduce violence and bullying, should be encouraged and promoted.

Factors associated with sleep quality among nurse managers during regular prevention and control of the COVID-19 in China: a cross-sectional study

BACKGROUND

Nurse managers play a pivotal role in quality patient care and staff satisfaction and retention. An overwhelming amount of work tasks and responsibilities might result in their sleep problems which are expected to aggravate in the context of the COVID-19, thereby affecting their overall health and work quality. However, little attention has been paid to sleep quality among nurse managers. This study aimed to investigate the prevalence of sleep disorders among nurse managers and identify related factors of sleep quality during regular prevention and control of the COVID-19 pandemic in China.

METHODS

This cross-sectional online survey was conducted in 14 hospitals on a sample of 327 nurse managers in China. Participants were invited to complete the general demographic questionnaire, Pittsburgh Sleep Quality Index (PSQI) and Simplified Coping Style Questionnaire (SCSQ). Multiple linear regression analysis was used to explore the influencing factors of sleep quality among nurse managers.

RESULTS

In this study, 43.7% of nurse managers suffered from sleep disorders. Active coping style and frequent exercise were positive factors that could influence nurse managers' sleep quality, while passive coping style and age over 41 years old were negative predictors, collectively accounting for 52.0% of the variance of sleep quality.

CONCLUSIONS

The issue of sleep disorders among nurse managers during regular epidemic prevention and control period is underscored. Coping style and demographic factors including age and frequency of exercise can significantly affect nurse managers' sleep quality. Healthcare administrators should pay more attention to nurse managers' sleep disorders and implement targeted strategies based on influencing factors to ensure their sleep quality.

Fear of recurrence in elderly patients with coronary heart disease: the current situation and influencing factors according to a questionnaire analysis

Objective

Fear of recurrence is a common psychosocial sequela among patients with heart disease. Analyses of coronary heart disease, particularly in elderly patients, are relatively rare. This study aimed to investigate the current situation in this context, as well as the influencing fear factors concerning recurrence in elderly patients with coronary heart disease.

Methods

A total of 200 elderly outpatients with coronary heart disease were recruited to participate in this survey from a tertiary hospital in Baoding (China). The questionnaires included items from the Disease Progression Simplified Scale, the Simplified Coping Style Questionnaire, and the Social Support Rating Scale (SSRS). Univariate and multivariate regression analyses were adopted to investigate the influencing factors on the fear of recurrence.

Results

The fear of recurrence score in elderly patients with coronary heart disease was (38.46 ± 8.13), among which 119 cases (59.5%) scored higher than 34 points. The SSRS total average score was (34.89 ± 9.83) points. Positive coping style and social support were negatively correlated with the total score of recurrence fear (r =  − 0.621, − 0.413, both P < 0.001). There was a positive correlation between negative coping style and the total score of recurrence fear (r = 0.232, P < 0.001). Multiple linear regression analysis showed that the course of the disease, the number of disease recurrence cases, active coping, and social support were relevant factors in fear of recurrence (all P < 0.05).

Conclusion

The detection rate of fear of recurrence in elderly patients with coronary heart disease was relatively high but could be reduced by active interventions and enhancing social support.

Psychological distress and its influencing factors among psychiatric nurses in China: A cross-sectional study

BACKGROUND

Psychiatric nurses often face abuse, attacks, escape, suicides, and other situations related to the care of patients with mental disorders, which are more likely to induce psychological distress.

AIMS

This study aimed to examine the relationship between coping styles and psychological distress among Chinese psychiatric nurses in Shandong and the significance of sleep quality as a mediating factor.

METHODS

A total of 812 psychiatric nurses in Shandong, China, were investigated using the Psychological Distress Scale (K10), Simplified Coping Style Questionnaire (SCSQ), Pittsburgh Sleep Quality Index (PSQI) and self-compiled general information questionnaire.

RESULTS

Psychological distress was detected in 571 psychiatric nurses (70.3%). The psychological distress of psychiatric nurses was significantly different with respect to professional title (χ² = 10.627, P < 0.05) and shift work (χ² = 9.120, P < 0.01). Psychological distress positively correlated with negative coping style (r = 0.266, P < 0.01) and sleep quality (PSQIT) (r = 0.532, P < 0.01). A significant positive correlation was found between psychological distress and all dimensions of sleep quality (r = 0.158-0.456, P < 0.05). Professional title, positive coping style, negative coping style, sleep quality (PSQIT), subjective sleep quality, sleep disorder and daytime dysfunction predicted psychological distress in psychiatric nurses (R ² = 0.363, F = 65.343, P < 0.01). The relationship between negative coping style and psychological distress was partially mediated by sleep quality, with the mediating effect accounting for 37.97% of the total effect.

CONCLUSIONS

Psychiatric nurses have a high rate of psychological distress, which is closely related to coping styles, and sleep quality has a certain regulatory effect.
