In network theory depression is conceptualized as a complex network of individual symptoms that influence each other, and central symptoms in the network have the greatest impact on other symptoms. Clinical features of depression are largely determined by sociocultural context. No previous study examined the network structure of depressive symptoms in Hong Kong residents. The aim of this study was to characterize the depressive symptom network structure in a community adult sample in Hong Kong during the COVID-19 pandemic. A total of 11,072 participants were recruited between 24 March and 20 April 2020. Depressive symptoms were measured using the Patient Health Questionnaire-9. The network structure of depressive symptoms was characterized, and indices of “strength”, “betweenness”, and “closeness” were used to identify symptoms central to the network. Network stability was examined using a case-dropping bootstrap procedure. Guilt, Sad Mood, and Energy symptoms had the highest centrality values. In contrast, Concentration, Suicide, and Sleep had lower centrality values. There were no significant differences in network global strength (p = 0.259), distribution of edge weights (p = 0.73) and individual edge weights (all p values > 0.05 after Holm–Bonferroni corrections) between males and females. Guilt, Sad Mood, and Energy symptoms were central in the depressive symptom network. These central symptoms may be targets for focused treatments and future psychological and neurobiological research to gain novel insight into depression.
These results proposed that intentional nursing rounds based on the care model were effective in improving perception of quality nursing care and patients' satisfaction with nursing care. Structured patient-oriented intentional nursing rounds based on the care model are expected to expand to a variety of clinical settings further.
Purpose:The purpose of this study was to determine the relationships among health locus of control, resilience, social support, and health promoting behavior in patients with coronary artery diseases. Methods: This study utilized a descriptive correlational design using a survey method. The subjects were 165 coronary artery disease patients at the cardiology out-patient clinic of the C university hospital. Data were collected through Health Locus of Control Scale, Resilience Scale, ENRICHD Social Support Instrument, Health Promoting Lifestyle Profile scale. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and hierarchial regression. Results: There were significant positive bivariate correlations of health promoting behavior with internal health locus of control, doctors health locus of control, resilience and social support respectively, and correlation between resilience and social support. Among predictors, internal health locus of control (β=.28), social support (β=.28) and resilience (β=.25) had statistically significant influences on health promoting behavior. Conclusion: These results proposed that internal health locus of control, social support and resilience have important influences on health promoting behavior. Nursing interventions to enhance internal health locus of control, resilience and social support might be essential for patients with coronary artery disease in order to promote their health behaviors.
The purposes of this study were to develop a scale to measure the grit for nurses and to examine the validity and reliability of the scale. Methods: Through a literature review and focus group interviews, 28 preliminary items were selected. After a content validity examination by experts, 35 items were chosen. The questionnaire survey for this study was conducted with 330 nurses from five hospitals in A city in Korea. Among them, 305 met the inclusion criteria for analyses. Results: From the exploratory factor analysis to determine validity, three factors were drawn. The variance explanation by the three factors was 56.62%, which means that the scale explained grit in clinical nurses. The three factors were labeled as 'sustained persistence' (5 items), 'consistency of interest as a nursing professional' (5 items), and 'Patient oriented intrinsic motivation' (4 items). The grit for criterion-related validity showed that the correlation coefficient was .53 (p<.001), validating the developed scale. For internal consistency, Cronbach's ⍺ coefficient was .91. Conclusion: Through the development process for the instrument as described above, the clinical nurses' grit was shown to have validity and reliability. Improving the grit of clinical nurses may contribute to prevention of turnover.
The study aimed to develop and test the Coronary Artery Disease Empowerment Scale in Korea and assess its initial aspects of validity and reliability. The participants included 301 patients diagnosed with coronary artery disease, receiving regular outpatient and inpatient care. Data were collected from August to December 2019. The exploratory factor analysis resulted in extracting 25 items and three factors—self-determination, emotional self-regulation, and personal competence of disease management perception—with a cumulative explanatory power of 55.40%. A significant correlation was found between the Korean versions of the Cardiac Self-efficacy Scale ( r = .31, p < .001) and the Health Empowerment Scale ( r = .45, p < .001). The internal consistency reliability of all items was .93. The developed instrument can be used to evaluate empowerment in patients with coronary artery disease and identify an improved instrument to measure empowerment. However, further testing of the newly developed Coronary Artery Disease Empowerment Scale is required.
Purpose: To develop nurses' educational needs scale for woman with infertility. Methods: A total of 201 nurses in charge of infertility health services in 4 infertility hospitals and 1 public health center were enrolled for this study. The scale was developed through literature review, in-depth interview, development of preliminary items, verification of content validity, development of secondary items, verification of construct validity, and extraction of final items. Data were analyzed using item analysis, exploratory factor analysis, Pearson's correlation coefficients, and Cronbach's α. Results: Nurses' educational needs scale for women with infertility consisted of 41 items. Three factors (education for disease and symptom of infertility, supporting and counselling for infertility patients, and education for daily life of infertile patients) explained 63.7% of the total variance. Conclusions: Nurses' educational needs scale for woman with infertility demonstrated acceptable validity and reliability. Its items could be used to assess the level of educational needs for nurses in charge of infertility health services.
Objective: This study aimed to evaluate the effects of warm humidification of anesthetic gas nursing care on physiological factors in elderly patients during laparoscopic cancer surgery. Methods: Sixty elderly laparoscopic surgical patients were recruited from a medical center in Korea. The participants’ physiological factors (blood pressure, body temperature, and leukocyte and neutrophil counts) were measured four times. Results: After warm humidification of anesthetic gas nursing care, there were significant differences in body temperatures. Conclusions: These findings indicate that warm humidification of anesthetic gas nursing care is effective in maintaining body temperature. Thus, this type of nursing care can be effective in elderly cancer patients undergoing laparoscopic surgery.
연구의 필요성우리나라Purpose: The purpose of this study was to identify the experiences of patients with ovarian cancer undergoing chemotherapy. Methods: A phenomenological method was used in this study. Data were collected by individual in-depth interviews with six participants with ovarian cancer undergoing chemotherapy during 2016. Colaizzi' s phenomenology has been adopted as a research method in this qualitative study. Results: Seven theme clusters were derived from the data as follows: 'Recognizing cancer diagnosis and treatment as braking in life, ' 'Effect on being a housewife as a cancer patient, ' ' Ambivalence about treatment, ' 'Fear with physical side effects, ' 'Losing sexuality as a woman, ' ' Affected by other ovarian cancer patients, ' 'Practice hope after treatment. ' Conclusion: Patients with ovarian cancer experienced tremendous physical and psychosocial problems. This finding demonstrates the need to develop appropriate nursing interventions for issues related to the experience of patients with ovarian cancer receiving chemotherapy.
