ObjectivesThis study aimed to examine the psychometric properties of the traditional Chinese version of the Youth Attitude to Noise Scale (YANS) in a large representative sample.DesignCross-sectional study.Setting15 secondary schools in Hong Kong, China.Participants2842 adolescents aged 12–20 years participated in this study between April and July 2016.MethodsThe standard forward–backward validation procedures were followed to obtain the traditional Chinese version of the YANS. Prior to the formal investigation, the YANS was evaluated by cognitive debriefing. The sample was randomly divided into two halves for exploratory factor analyses (EFAs) and confirmatory factor analyses (CFAs), respectively. The number of factors was determined by comparison data approach using EFAs, and the factor structure was confirmed by CFAs using the one-factor, four-factor and bifactor models. The scale’s internal reliability, dimensionality and measurement invariance across gender and age groups were also examined.ResultsEFAs (n=1338) showed that four factors were extracted, and CFAs (n=1337) demonstrated the bifactor model fitted better to the sample than the other models. Additionally, the traditional Chinese version of the YANS showed high reliability (ω=0.84), a general factor, scale multidimensionality, and gender and age invariance.ConclusionsThe findings of the current study indicate that the traditional Chinese version of the YANS is a feasible instrument to assess attitude to noise in Chinese adolescents, regardless of their gender and age. Given the presence of a general factor, the YANS is not merely multidimensional, and whether to use the total or subscale scores is recommended to rely on research objectives.

ObjectivesThe aims of this study were to develop the Chinese version of the Communication Skills Attitude Scale (CSAS-Ch) in order to test the psychometric properties of the modified instrument.DesignA cross-sectional study was conducted in September 2016 to evaluate the attitudes of Chinese medical students towards communication skills learning using CSAS at China Medical University.ParticipantsThe study recruited 510 fifth-year medical students by cluster sampling.MethodsCronbach’s α coefficients were calculated for the entire questionnaire and for the subscales to evaluate the internal consistency of the CSAS-Ch. In order to determine the structure underlying the CSAS, the scale was factor analysed using maximum likelihood extraction and the oblique rotation method.ResultsOf the 510 medical students, 492 (96.5%) completed the questionnaire. Cronbach’s α coefficient for the CSAS scale was 0.897. Exploratory factor analysis showed that the four-factor structure accounted for 59.8% of the variance and produced an acceptable fit to the data.ConclusionsThe modified CSAS-Ch can be used to evaluate attitudes towards communication skills. Further Future research for improving the teaching methods for communication skills should explore the relationship between medical students’ attitudes and the demographic characteristics.

Background: The role of serum calcium in coronary artery disease (CAD) patients with or without first incident acute myocardial infarction has not been studied previously. This study aimed to assess the relationship between serum calcium and first incident acute myocardial infarction. Methods: This cross-sectional study was conducted from Jan 2014 to Dec 2016. All the participants were from our database, described in detail elsewhere including 1609 cases and 3252 controls. Multiple logistic regression was carried out to explore the effect of serum calcium on first incident acute myocardial infarction. Interaction between serum calcium and risk factors were evaluated. Results: Patients with first incident acute myocardial infarction have significantly lower serum calcium concentrations than those without acute myocardial infarction (2.18 (0.21) vs 2.24 (0.19) mmol/L, P<0.0001). After adjusting for sex and age, logistic regression showed that serum calcium was significantly associated with first incident acute myocardial infarction (odds ratio (OR): 1.50, 95% confidence interval (CI): 1.41-1.60). Further adjusted for potential confounders, serum calcium was associated with first incident acute myocardial infarction (OR: 1.32, 95% CI: 1.22-1.42). Moreover, the association still existed when patients were divided into subgroups according to gender and age. A significant interaction was found between serum calcium and diabetes mellitus (DM), lipoprotein (a) (Lp (a)), and serum albumin. Conclusion: Serum calcium was associated with first incident acute myocardial infarction among CAD patients in both sexes and in age categories. This study provides further evidence showing the value of serum calcium levels in clinical practice.

The Relationship

This cross-sectional study aimed to investigate the relationship between caregivers and care receivers, defined as home-dwelling family members with dementia. We used a self-rating questionnaire, the Felt Expressed Emotion Rating Scale (FEERS; 6 simple questions), to measure caregiver perceptions of the care receiver’s criticisms (CCs) and emotional overinvolvement (EOI) toward the caregiver. We performed factor analyses to rank single items on the FEERS pertaining to CC and EOI. We included 208 caregiver/care receiver pairs. Logistic regression analyses tested associations between FEERS items and caregiver and care receiver variables. The main contributors to caregiver perceptions of CC were the caregiver’s own distress and the amount of time spent with the care receiver. Socially distressed caregivers perceived the care receiver as emotionally overinvolved. When offering a psychosocial intervention, a tailored program should target the caregiver’s perceived relationship with the family member and the caregiver’s distress. The program should also endeavor to give the caretaker more opportunities for leisure time.
