    STUDY PURPOSE: This study was conducted to examine the relationship between religious practice, religious coping methods and psychological distress among parents caring for children with transfusion-dependent thalassemia.

    DESIGN AND METHODS: This is a cross-sectional survey. Data were collected on 162 parents of children diagnosed with thalassemia aged 12 years and younger in thalassemia day care centers of three public hospitals in Sabah, Malaysia. Data were collected using questionnaires, including General Health Questionaire-12 (GHQ-12), Duke University Religion Index (DUREL) and Brief RCOPE.

    RESULTS: Forty-two percent of parents had psychological distress with GHQ score ≥ 3 (mean score of 2.85 ± 3.17). Ninety-five percent of parents used positive religious coping methods (mean P-COPE score 22.35 ± 2.33) more than negative religious coping methods (mean N-COPE score was 12.19 ± 5.23). They used Organized Religious Activities (mean ORA score of 4.20 ± 1.27), and Non-Organized Religious Activities (NORA, the mean was 4.17 ± 1.37). Positive and negative religious coping methods were significantly related to parents' psychological distress (P-COPE and GHQ-12 scores (rs (df) = 0.19, p

    BACKGROUND: Studies have reported that student nurses hold positive attitudes towards older people; nevertheless, working with older people has consistently remained one of the least desired career choices among student nurses in most countries.

    OBJECTIVES: The current study aimed to assess student nurses' intentions to work with older people and to determine the predictors of working intentions among nursing students.

    DESIGN: The study adopted a cross-sectional design.

    SETTINGS: Multistage sampling was used to recruit nursing students from five states in Malaysia.

    PARTICIPANTS: A total of 1462 nursing students from eleven nursing education institutions participated in this study.

    METHODS: A self-administered questionnaire was used to collect data. This study is underpinned by the Theory of Planned Behaviour. The Intent to Work with Older People Scale and Kogan Attitudes Toward Old People Scale were used to assess nursing students' intentions and attitudes towards care of older people respectively. Researcher-developed instruments were used to assess subjective norms and perceived behavioural control among nursing students.

    RESULTS: The present study found that nursing students in Malaysia demonstrated a moderate level of intention to work with older people, with a mean of 39.72 (±4.38). There were significant differences in effects of gender, ethnic group, academic level, type of nursing institution and setting of older person care clinical experience on intentions to work with older people. There was a moderate and positive relationship between attitudes towards older people and intentions to work with older people, as well as between perceived behavioural control and intentions to work with older people; it was found that r = 0.36 for both relationships. Attitudes, subjective norms and perceived behavioural control accounted for 19.7% of the variance in intentions to work with older people.

    CONCLUSION: The primary findings of this national study revealed that Malaysian nursing students have a moderate level of intention to work with older people. It is imperative to develop educational interventions to nurture attitudes for caring and promote stronger intentions to work with older people.

    Acute physiological, perceptual and biomechanical consequences of manipulating both exercise intensity and hypoxic exposure during treadmill running were determined. On separate days, eleven trained individuals ran for 45 s (separated by 135 s of rest) on an instrumented treadmill at seven running speeds (8, 10, 12, 14, 16, 18 and 20 km.h-1) in normoxia (NM, FiO2 = 20.9%), moderate hypoxia (MH, FiO2 = 16.1%), high hypoxia (HH, FiO2 = 14.1%) and severe hypoxia (SH, FiO2 = 13.0%). Running mechanics were collected over 20 consecutive steps (i.e. after running ∼25 s), with concurrent assessment of physiological (heart rate and arterial oxygen saturation) and perceptual (overall perceived discomfort, difficulty breathing and leg discomfort) responses. Two-way repeated-measures ANOVA (seven speeds × four conditions) were used. There was a speed × condition interaction for heart rate (p = 0.045, ηp2 = 0.22), with lower values in NM, MH and HH compared to SH at 8 km.h-1 (125 ± 12, 125 ± 11, 128 ± 12 vs 132 ± 10 b.min-1). Overall perceived discomfort (8 and 16 km.h-1; p = 0.019 and p = 0.007, ηp2  = 0.21, respectively) and perceived difficulty breathing (all speeds; p = 0.023, ηp2  = 0.37) were greater in SH compared to MH, whereas leg discomfort was not influenced by hypoxic exposure. Minimal difference was observed in the twelve kinetics/kinematics variables with hypoxia (p > 0.122; ηp2 = 0.19). Running at slower speeds in combination with severe hypoxia elevates physiological and perceptual responses without a corresponding increase in ground reaction forces.Highlights The extent to which manipulating hypoxia severity (between normoxia and severe hypoxia) and running speed (from 8 to 20 km.h-1) influence acute physiological and perceptual responses, as well as kinetic and kinematic adjustments during treadmill running was determined.Running at slower speeds in combination with severe hypoxia elevates heart rate, while this effect was not apparent at faster speeds.Arterial oxygen saturation was increasingly lower as running speed and hypoxic severity increased.Overall perceived discomfort (8 and 16 km.h-1) and perceived difficulty breathing (all speeds) were lower in moderate hypoxia than in severe hypoxia, whereas leg discomfort remained unchanged with hypoxic exposure.

    BACKGROUND: Understanding the factors influencing nurses' turnover intention, particularly the work life quality and commitment to organization, is important to all countries suffering from nursing shortage. The study aims to determine the mediating role of commitment to organization on work life quality and its relationship with turnover intention among Malaysian nurses.

    METHODS: A descriptive cross-sectional design, using a self-report survey was conducted on 430 nurses from a teaching hospital from February to April 2019. A structural equation model version 3 was used for testing study hypotheses.

    RESULTS: The mediating effect (indirect effect) of organizational commitment on the relationship between work life quality and turnover intention (QWL→OC→IT) was negative with path coefficient - 0.234, whereas the direct effect of work life quality on turnover intention (QWL→IT) was negative with smaller path coefficient - 0.228. This means that the relationship between work life quality and turnover intention was partially mediated by the organizational commitment (P < 0.001).

    CONCLUSION: Organizational commitment has a negative partial mediating effect between work life quality of nurses and intention of turnover in teaching hospitals where the organizational commitment significantly reduced the nurses' intention to leave. The study findings can guide nursing managers to be carefully attended to the levels of nurses' commitment to their organization.

    Depression leads to a poorer quality of life (QOL) which is a determinant of healthy ageing. Cost-effective solutions for enhancing QOL in the older population are much needed in China, with its rapidly ageing population. We conducted a randomized controlled trial involving 112 community-dwelling older participants with mild to moderate depression, to evaluate the effect of Tai Chi with music on QOL (57 in intervention group, 55 in control group). WHO Quality of Life-BREF was used to measure QOL at baseline and at every month for three months. Following the adjustments for sociodemographic data, the effect of intervention on QOL was assured (F = 25.145, P

    BACKGROUND: The effectiveness of pharmacological treatment may be limited in older persons. Several studies using Tai Chi or music therapy separately confirmed positive effects in the reduction of depressive symptoms. We conducted a cluster randomized controlled trial to evaluate the possible synergistic effect of combined music and Tai Chi on depressive symptoms.

    METHODS: One hundred and seven older adults with mild to moderate depressive symptoms were recruited from Ya'an city. Fifty-five participants were cluster randomized to combined music and Tai Chi group for three months, while the other fifty-two individuals were randomized to the control group that entailed routine health education delivered monthly by community nurses. The primary outcome of depressive symptoms was measured with the Geriatric Depression Scale (GDS) at baseline and monthly for three months.

    RESULTS: At three-month follow-up, a statistically significant improvement in depressive symptoms was found in the intervention group compared with control group (F(3,315) = 69.661, P < 0.001). Following adjustments for socio-demographic data, the true effect of intervention on depressive symptoms was significant (F = 41.725, P < 0.01, ηp2 = 0.574).

    CONCLUSIONS: Combined music and Tai Chi reduced depressive symptoms among community-dwelling older persons. This represents an economically viable solution to the management of depression in highly populous developing nations.

    The current study examines the public's perception on the mitigation of COVID-19 risk and knowledge of disease symptoms among older adults in nursing homes, with the intention to address gaps in knowledge using mobile technologies. An online survey questionnaire was completed by 611 adults residing in Malaysia. The four domains, derived from factor analysis, affirmed the supportive perception among the public (score range = 4.42 to 4.64/5.0). However, among the gaps identified were the perception toward hand sanitizing and susceptibility of older adults to COVID-19. Public knowledge on symptoms of COVID-19 was limited (e.g., 41.4% to 53.4% incorrect responses to anosmia, diarrhea, confusion). Multivariate analysis of variance found that males and participants with less education had significantly lower supportive perceptions (p < 0.05). With >86% of participants having access to internet communication technology, mobile interventions tailored to gender and educational level are recommended to promote long-term pandemic preparedness among stakeholders and the public.

    Objective: As the incidence of emergencies has steadily increased in recent years, it is important to en-sure that individuals, including university students, are adequately trained to deal with such events. This study aimed to assess the level of knowledge and awareness of, and attitudes towards, first aid among IIUM Kuantan campus students.

    Method: A quantitative cross-sectional survey with stratified random sam-pling study was conducted among 348 students at the International Islamic University Malaysia (IIUM) Kuantan. Data were collected using a self-administered questionnaire which was adapted from Hong Kong Red Cross. The questionnaire was available in both English and the Malay language.

    Results: A total of 42.8% participants had a moderate level of first aid knowledge. However, 90.8% participants had aware-ness of and a positive attitude towards first aid knowledge. On the other hand, 55.4% of study participants had not experienced taking first aid courses and they had little knowledge of this. There were significant associations between gender, Kulliyyah or faculty, year of study, and first aid training experience, and the level of first aid knowledge based on a one-way ANOVA test with p-values of < 0.05 representing statistical significance.

    Conclusion: The findings indicate that most health sciences university students have good awareness and attitudes towards first aid. Nevertheless, implementation of regular educational programs with structured modules may be able to improve their knowledge of first aid practices and skills.

    BACKGROUND: Social disengagement among older persons may result from accumulated physical impact and social stressors experienced throughout life. Conversely, interventions that enhance social participation addresses social isolation with positive influences on health. This article, therefore, aimed to review the range of published studies that evaluated the health benefits of interventions on social participation among community-dwelling older persons.

    METHOD: We conducted a search using the databases CINAHL, MEDLINE, EBSCOhost, PubMed, ProQuest, SAGE, ScienceDirect, SpringerLink, Web of Science, and Open repository/archive.

    RESULTS: Twenty-five studies from Asia, Europe and America were selected. Included articles described randomized controlled trials (9), quasi-experimental studies (9), mixed-methods studies (2), participatory action research (3), and community-based intervention research (2). Social interventions described are group or cultural activities, personal/group monitoring and discussion, and communications devices. Intervention designed utilized theories, models, concepts, principles, and evidence from published literature.

    CONCLUSION: Most social intervention studies evaluating health outcomes have been conducted in North America and Western Europe. Group-based activities were most commonly employed, but personal/group discussions, home visits and technology-based interactions have also been used. While social isolation is now a widely accepted risk factor for ill-health, research evidence for improvement of health through reduction of social isolation remains limited.

    AIMS: To review systematically the psychometric properties of instruments used to measure intention to work with older people.

    BACKGROUND: Nursing students are part of the future healthcare workforce; thus, being aware of their intention to work with older people would give valuable insights to nursing education and practice. Despite a plethora of research on measuring intention to work with older people, a valid and reliable instrument has not been identified.

    DESIGN: A systematic literature review of evidence and psychometric properties.

    DATA SOURCES: Eight database searches were conducted between 2006 - 2016.

    REVIEW METHODS: English articles were selected based on inclusion and exclusion criteria. The COSMIN checklist was used to assess instruments reporting a psychometric evaluation of validity and reliability.

    RESULTS: Of 41 studies identified for full text review, 36 met the inclusion criteria. Seven different types of instruments were identified for psychometric evaluation. Measures of reliability were reported in eight papers and validity in five papers. Evidence for each measurement property was limited, with each instrument demonstrating a lack of information on measurement properties. Based on the COSMIN checklist, the overall quality of the psychometric properties was rated as poor to good.

    CONCLUSION: No single instrument was found to be optimal for use. Studies of high methodological quality are needed to properly assess the measurement properties of the instruments that are currently available. Until such studies are available, we recommend using existing instruments with caution.

    BACKGROUND: Because nurses need to handle a broad range of issues related to patients' health status, it is necessary to make reliable and sound clinical judgments for professional accountability and the patients' safety.

    METHOD: A quasi-experimental pre- and posttest design with a control group was used to study the effectiveness of an educational intervention on the clinical judgment skills of 80 RNs from two district hospitals. The change in clinical judgment skills during a 6-week period was evaluated using a complex case-based scenario after the completion of the educational intervention.

    RESULTS: The mean scores of clinical judgment skills of the experimental group had significantly improved from 24.15 ± 6.92 to 47.38 ± 7.20. (p < .001). However, only a slight change was seen in mean scores for the control group (23.80 ± 5.77 to 26.50 ± 6.53).

    CONCLUSION: The educational intervention was effective postintervention. Continuing nursing education using a traditional and case-based method is recommended to improve clinical judgment skills in clinical settings. J Contin Educ Nurs. 2017;48(8):347-352.

    BACKGROUND: Undergraduate nursing students are required to acquire professional values during professional nurse education to provide safe and high quality patient care. However, there was no documentation in professional values among Indonesian undergraduate nursing students and the factors influencing its development.

    PURPOSE: The purpose of this study was to determine professional values among Indonesian undergraduate nursing students and examine the relationship between students' demographic factors and professional values.

    DESIGN: A cross-sectional study using convenience sampling was applied to recruit 391 Indonesian undergraduate nursing students. The 26 items of Nurses Professional Values Scale Revision (NPVS-R) with five dimensions was employed to collect data. Descriptive and inferential statistics, independent samples t-test were applied to analyse and interpret data.

    RESULTS: The result showed that the total score of nurse professional values was high (95.80 ± 12.93). The most important professional value dimension was caring, while activism was the least important values. The NPVS-R total score had a significant association with length of professional clinical practice of the students (p

    OBJECTIVE: End-of-life care is often overlooked in the dialysis unit despite high mortality rates. This study aimed to understand the diverse subjectivity of opinions on end-of-life care preferences, feelings, needs, value and goals in life among a haemodialysis population.

    METHODS: The Q methodology was used where 37 opinion statements were ranked in order of importance in a unimodal shaped grid. Results were explored using the Centroids factor extraction and Varimax rotation.

    RESULTS: Four-three persons living with haemodialysis, mean age± SD= 56.58 ± 10.22 years, participated in the study. Five-factors were identified: living in the present, family preference, self preservation, power vs. control and autonomy in decision making, loaded by eleven, four, four, three and three participants with 16 individuals not loading significantly and two were confounded. Preferences for remaining positive in the face of illness through a healthy lifestyle and preserving relationships and autonomy were demonstrated.

    CONCLUSIONS: End-of-life discussions are potentially inhibited by preferences to live for the present which should be explored in future studies.

    PRACTICE IMPLICATION: Statement sets may be used to help facilitate end-of-life discussions through identification of opinion groups. Establishing preferences may guide identification of those willing to initiate discussions.

    BACKGROUND: Complementary foods with breastfeeding are foods or drinks given to children aged 6-23 months to meet their nutritional needs. The non-optimal provision of complementary feeding influences malnutrition in children of this age.

    AIMS: To analyze the factors associated with complementary feeding practices among children aged 6-23 months in Indonesia.

    METHODS: A cross-sectional design was employed using data from the 2017 Indonesia Demographic and Health Survey. A total of 502,800 mothers with children aged 6-23 months were recruited through multistage cluster sampling. Data were analyzed using a logistic regression test to determine the correlation between predisposing, enabling, and reinforcing factors and complementary feeding practices.

    RESULTS: A prevalence values of analysis showed that approximately 71.14%, 53.95%, and 28.13% of the children met MMF, MMD, and MAD, respectively. The probability of achieving minimum dietary diversity (MDD) was high in the following: children aged 18-23 months (odds ratio [OR] = 9.58; 95% confidence interval [CI] = 7.29-12.58), children of mothers with higher education (OR = 5.95; 95% CI = 2.17-16.34), children from households with upper wealth index (OR = 2.53; 95% CI = 1.85-3.48), children of mothers who received childbirth assistance by professionals (OR = 1.63; 95% CI = 1.20-2.20), and children of mothers who had access to the Internet (OR = 1.26; 95% CI = 1.06-1.50). Moreover, children from households with the upper wealth index (OR = 1.40; 95% CI = 1.03-1.91), children whose mothers were employed (OR = 1.19; 95% CI = 1.02-1.39) living in urban areas (OR = 1.28; 95% CI = 1.06-1.54) and children of mothers who received childbirth assistance by professionals (OR = 1.33; 95% CI = 0.98-1.82) were more likely to meet Minimum Meal Frequency (MMF). Finally, children aged 18-23 months (OR = 2.40; 95% CI = 1.81-3.17), of mothers with higher education (OR = 3.15; 95% CI = 0.94-10.60), from households with upper wealth index (OR = 1.41; 95% CI = 1.05-2.90) and born with professional childbirth assistance (OR = 1.82; 95% CI = 1.21-2.75) were significantly associated with minimum acceptable diet (MAD).

    CONCLUSIONS: The findings revealed that the prevalence of MDD and MAD in Indonesia was low. Strategies such as improving health services, economic conditions, and education level of mothers are needed to improve infant and young child feeding in Indonesia.

    BACKGROUND: Studies have shown that second-victim experiences could increase risks of the compassion fatigue while support from individuals and organisations is most often protection. However, the risk for poor compassion satisfaction and increased compassion fatigue in nurses aroused by adverse events remains an underestimated problem, meanwhile, litter known about the role of positive and negative coping styles among nurses suffering from adverse events. This study aims to investigate the effect of second-victim experiences on the professional quality of life among nurses and to determine the mediating role of coping styles in the relationship between second-victim experiences and professional quality of life.

    METHODS: Multistage sampling was used to recruit registered nurses from Hunan province in China. Registered nurses who identified themselves as experiencing adverse events from nine tertiary hospitals were included in this study. Participants were recruited to complete a survey on the second victim experience and support tool, the simplified coping style questionnaire, and the professional quality of life scale. The stress coping theory was used to develop the framework in this study. The structural equation modelling approach was used for conducting the mediating effects analysis via IBM SPSS Statistics 26.0 and Mplus 8.3.

    RESULTS: In total, 67% (n = 899) of nurses reported a second victim experience during their careers. In a bivariate analysis, both second-victims experiences and coping styles were significantly associated with their professional quality of life. The results showed that the effects of second victim experiences on their professional quality of life were fully mediated by coping styles. A total of 10 significantly indirect pathways were estimated, ranging from -0.243 to 0.173.

    CONCLUSIONS: Second-victim experiences are common among nurses in this study. Since the mediating effects of coping styles were clarified in this study, it is imperative to promote the perception of negative coping styles and encourage nurses to adopt more positive coping styles with adequate support systems.

    BACKGROUND: Malnutrition is common among patients with cancer, but little attention is given to its risks and consequences.
    OBJECTIVES: The aim of this study is to assess the nutritional status and identify the factors associated with malnutrition among newly diagnosed patients with cancer.
    METHODS: Patients admitted with newly diagnosed cancer at a teaching hospital in Malaysia were recruited from January to April 2015. Nutritional status was assessed before treatment initiation, and patients were classified into three categories.
    FINDINGS: A total of 132 pretreatment patients were recruited into the study. About half were severely malnourished. Patients with stage III cancer had the highest prevalence of severe malnourishment. Clinical parameters and disease characteristics were significantly associated with nutritional status. Demographic variables were also statistically significantly associated with severe nutritional status.

    BACKGROUND: Adaption to clinical work during the internship can induce several stressors among medical students, especially in the context of the coronavirus disease 2019 (COVID-19) pandemic. Particularly, job stress could be linked to the development of psychological traits and the formation of the professional identity of medical interns.

    OBJECTIVE: This study aimed to explore the relationship between job stress, psychological capital, and professional identity through a mediation analysis of Chinese medical interns.

    METHODS: A descriptive cross-sectional study was conducted in 30 hospitals and clinics in China from June 2021 to March 2022. A total of 665 medical interns filled out questionnaires related to demographic questions, psychological capital, job stress, and professional identity. Data analysis was executed using the IBM SPSS version 22.0 software and its add-in PROCESS Windows version 4.0.

    RESULTS: The findings indicated a statistically significant mediating effect of psychological capital between job stress and professional identity. Job stress and job stress combined with psychological capital accounted for 5.3% and 37.9%, respectively, of the variance in professional identity. The bootstrapping method corroborated the significance of the indirect effect of job stress through psychological capital (95% bootstrap CI = -4.7921, -2.4345).

    CONCLUSION: The current findings underscore the need for increased attention on improving the psychological capital of medical interns.

    Obesity is a major global health issue and a primary risk factor for metabolic-related disorders. While physical inactivity is one of the main contributors to obesity, it is a modifiable risk factor with exercise training as an established non-pharmacological treatment to prevent the onset of metabolic-related disorders, including obesity. Exposure to hypoxia via normobaric hypoxia (simulated altitude via reduced inspired oxygen fraction), termed hypoxic conditioning, in combination with exercise has been increasingly shown in the last decade to enhance blood glucose regulation and decrease the body mass index, providing a feasible strategy to treat obesity. However, there is no current consensus in the literature regarding the optimal combination of exercise variables such as the mode, duration, and intensity of exercise, as well as the level of hypoxia to maximize fat loss and overall body compositional changes with hypoxic conditioning. In this narrative review, we discuss the effects of such diverse exercise and hypoxic variables on the systematic and myocellular mechanisms, along with physiological responses, implicated in the development of obesity. These include markers of appetite regulation and inflammation, body conformational changes, and blood glucose regulation. As such, we consolidate findings from human studies to provide greater clarity for implementing hypoxic conditioning with exercise as a safe, practical, and effective treatment strategy for obesity.

    OBJECTIVES: To validate and determine the psychometric properties of the Malay version of the endometriosis health profile-30 (EHP-30) by confirmatory factor analysis.

    METHODS: A cross-sectional study was carried out in the main city of Malaysia at a tertiary teaching hospital between January to April 2021. A total of 218 women diagnosed with endometriosis symptoms were recruited using the universal sampling method to answer the questionnaire.

    RESULTS: The revised Malay version of the EHP-30 with 28 items demonstrated that the factor loading of the 28 items had an acceptable value range between 0.60-0.90. The model fit was acceptable after the inclusion of 28 items correlated errors of the root mean square of error approximation: 0.072, 90% confidence interval: [0.065-0.080], comparative fit index (0.939), Tucker-Lewis index (0.932), and Chi-square/degrees of Freedom (2.135). The Cronbach's alpha ranged from 0.89-0.97. Concurrent validity for the composite reliability was between 0.88-0.96, while the average variance extracted was between 0.65-0.74.

    CONCLUSION: This revised Malay version of the EHP-30 is a reliable and valid tool that can be used for the next study.
