The Development and Validation of a Psychometric Tool to Assess Behavioral Factors Impacting Personal Dosimeter Use among Medical Radiation Workers.

ABSTRACT: Personal dosimeters are used by medical radiation workers (MRWs) to monitor their radiation dose from external sources and comply with radiation safety guidelines. Nevertheless, there is evidence of inconsistent use of the devices among MRWs. Behavioral factors influencing the use of personal dosimeters have never been explored. Using established behavioral models, we aimed to develop a psychometric tool to measure the behavioral factors influencing dosimeter use and establish its feasibility, reliability, and validity. A 37-item tool was developed based on a qualitative study and review of the literature. The content relevancy was assessed by six field experts before it was piloted and re-tested on MRWs. The construct validity of the tool was analyzed using exploratory factor analysis to confirm its psychometric properties. Face validation was performed by academicians, field experts, and MRWs to enhance the tool's readability. The 37 items in the tool belonged to five constructs in the early phase. However, the validation study revealed a reliable 27 item tool with seven constructs, namely: "Attitude," "Social factors," "Ability to perform if facilitated," "Ability to overcome shortcomings," "Self-efficacy," "Complexity," and "Perceived usefulness." The item-construct validity index of accepted items was >0.83, and Cronbach's alpha for each construct ranged between 0.70 to 0.96, while factor loading for each item was between 0.723 to 0.963. All results were considered "good" and "excellent." The new tool appears to be valid, reliable, and feasible to measure behavioral factors influencing personal dosimeter use among MRWs, which is helpful to facilitate the planning of interventions to improve behaviors in occupational radiation monitoring.

Prevalence and characteristics of e-cigarette users among Malaysian current and ex-smokers

@#Introduction: Electronic cigarettes (ECs) are new devices that have been accepted widely by both smokers and non-smokers. However, the evidence on EC used in Malaysia is scarce. The objective of thisstudy was to determine the prevalence of EC use and the socio-demographic and smoking characteristicsassociated with current EC use among Malaysian current and ex-smokers. Methods: This was a sub-analysis of data from a cross-sectional, national-population- based EC study conducted from May to June in 2016 in Malaysia. A detailed description of the sampling methods can be found in the National E-cigarette Survey (NECS) 2016 report. Briefly, data were obtained from 1396 individuals who had ever been smokers, i.e., 957 (68.6%) current smokers and 439 (31.4%) ex-smokers. Results: Current EC use was found predominantly among current smokers (8.0%) as compared with ex-smokers (4.3%). Among current smokers, the main reasons given for smoking ECs were wanting to try it (44.7%), followed by intention to quit tobacco smoking (15.8%) and to reduce tobacco smoking (10.5%). Using multiple logistic regression analysis, we found that among current smokers, current EC users were more likely to be younger, i.e., 18-44 years (aOR= 4.83, 95% CI= 1.97-11.86, p=0.001), urban residents (aOR= 1.89, 95% CI= 1.15-3.11, p=0.012), single/ divorced/ widowed (aOR= 2.11, 95% CI= 1.24-3.61, p=0.006) and students (aOR= 2.25, 95% CI= 1.01-5.01, p=0.048). Among exsmokers, only younger respondents (18-44 years old) was reported as being more likely to be current EC users (aOR= 3.81, 95% CI= 1.14-12.76, p=0.030). Conclusion: This study showed that currently using and ever having used ECs were more prevalent among current smokers. The reasons given for initiating EC use among current smokers were mainly wanting to try it, followed by intention to quit and to reduce tobacco smoking. Current EC use appears to be common among current smokers who are younger, urban residents, single/divorced/widowed and students. Therefore, EC cessation intervention strategies and policies should target these high-prevalence groups

Structured Debriefings in Aviation Simulations: A Qualitative Study on Basic Life Support Training for Cabin Crews in Malaysia

Abstract@#Introduction: To develop quality cabin crews, trainings involve simulation-based education (SBE) with structured debriefings – a significant component which plays a critical role in optimising learning outcomes. Previous studies have empirically tested the efficacy of the DIAMOND-structured debriefing model and found significant improvement and retention of the cabin crews’ knowledge and skills. This study was aimed to explore the elements of the DIAMOND-structured debriefing model that have been known to promote the acquisition and retention of knowledge and skills in basic life support (BLS). Methods: A qualitative study was conducted with a random sample of 16 individual cabin crew members who participated in an in-depth interview with 13 open-ended questions for 45 – 60 minutes. The interviews were transcribed and independently analysed using inductive thematic analysis. Results: The codes which have emerged during data analysis were clustered into three themes: (1) Cognitive, with three subthemes: engagement, learning environment, and ability to reflect; (2) Methodology, with three sub-themes: concept of debriefing, techniques of questioning, and additional elements; as well as (3) Psychosocial, with five sub-themes: attitude, self-awareness, relationships, self-confidence, and work culture. Several suggestions have emerged, such as the implementation of the model. Conclusion: The DIAMOND-structured debriefing model was a method to reduce cognitive load, which in turn allowed individuals to organise their knowledge, reflect individually and collectively, as well as structure their ideas. It has showed that the elements has a positive impact on the cabin crews’ acquisition and retention of knowledge and skills which will improve the performance and patient safety

Predicting Burnout And Psychological Distress Risks Of Hospital Healthcare Workers

@#Burnout and psychological distress were reported at higher rates among hospital healthcare workers. Despite this, there is a paucity of research examining the associated risk factors among workers across specialties and occupations in Asia. This paper aimed to examine the risk factors associated with burnout and psychological distress among Malaysian hospital healthcare workers from diverse medical specialties and occupations. A total of 368 doctors, nurses, assistant medical officers and hospital attendants were recruited from major medical and surgery departments in an urban general hospital. The participants were self-administered a questionnaire consisting of demographic information, Maslach Burnout Inventory-Human Services Survey and Depression Anxiety and Stress Scale. In the fully adjusted multivariate analyses, doctors were about four to five times more likely to be emotionally exhausted (aOR [adjusted Odds Ratio], 4.826; 95% CI [Confidence Interval]: 1.492-15.604, p<0.01), depressed (aOR, 5.221; 95% CI: 1.995-13.661, p<0.01) and stressed (aOR, 3.990; 95% CI: 1.473-10.809, p<0.01). Paediatric workers demonstrated three to five times higher risks of depression (aOR, 3.105, 95% CI: 1.043-9.243, p<0.05), anxiety (aOR, 3.517, 95% CI: 1.194- 10.356, p<0.05) and stress (aOR, 5.404, 95% CI: .1.628-17.942, p<0.01). Emotional exhaustion (aOR, 1.046, 95% CI: .1.013-1.079, p<0.01) and depersonalization (aOR, 1.078, 95% CI: .1.015-1.145, p<0.05) led to higher risks of psychological distress, while stress predicted higher risks of burnout (aOR, 1.153, 95% CI: 1.062-1.251, p<0.01). There were occupational and departmental differences in susceptibility to burnout and psychological distress, requiring further investigation into the unique working environments and roles of hospital healthcare workers.

Juara Sihat: assessing the sustained impact of a school-based obesity intervention

Introduction: Obesity and physical inactivity among schoolchildren are among the most challenging health problems inMalaysia. The present study aimed to evaluate the sustainedimpact of Juara Sihat programme on physical activity leveland anthropometric status at 18-month post-intervention.Method: Participants of Juara Sihat (n=55) were followed-upat 18 months after completion of the intervention. JuaraSihat intervention was implemented over 12 weeks andfocused on four key components: (i) five one-hour nutritioneducation classes, (ii) four one-hour physical activityeducation sessions, (iii) family involvement, and (iv)empowerment of Parents and Teachers Association.Anthropometric variables (body mass index, body fatpercentage and waist circumference) were measured andphysical activity level was evaluated by using PhysicalActivity Questionnaire for Children (PAQ-C) at baseline (P0),immediately upon completion of intervention (P1), atthree-month post-intervention (P2), and at 18-month postintervention(P3). Analyses of repeated measures analysisof covariance (ANCOVA) with intention-to-treat principlewere applied.Results: Sustained effects were found in BMI-for-age z-scorewhich showed a reduction (P0 2.41±0.84 vs P3 2.27±0.81)and physical activity level which showed positiveimprovements (P0 2.46±0.62 vs P3 2.87±0.76) at 18 monthsafter intervention was completed. Body fat and waistcircumference had increased over the same time period.Conclusion: Overall, this study successfully demonstratedsustained intervention effects of Juara Sihat intervention onBMI-for-age z-score and physical activity, but not on body fatpercentage and waist circumfere
