Introduction: Emotional intelligence (EI) is deemed an important aspect of being good medical doctors. Universiti Sains Malaysia (USM) Emotional Quotient Inventory (USMEQ-i) is an EI inventory in Malay language developed primarily as medical student selection tool in USM. Although it was already validated by exploratory factor analysis (EFA), EFA is considered insufficient evidence of construct validity, thus confirmatory factor analysis (CFA) was conducted. Objectives: To determine measurement model validity and construct validity of USMEQ-i among medical degree program applicants in USM by CFA. Methods: USMEQ-i data file for medical degree program applicants in USM for year 2010/2011 and 2011/2012 academic sessions were obtained from Medical Education Department in USM. A random sample of 512 cases was drawn from the data file. Of the sample, only 453 cases were valid study sample after preliminary data screening and assumption checking. CFA was conducted on the sample using maximum likelihood (ML) estimation with bootstrapping technique due to violation of multivariate normality assumption. USMEQ-i measurement model was proposed as a second-order EI factor with seven first-order factors of EI and a Faking Index (FI) factor, with correlation between second-order EI factor and FI factor. Results: The proposed model could not be fit into the study sample data. EI factors and FI factor had to be analyzed separately due to non-positive definite problem. After modifications to the model, CFA of EI factors were suggestive of two-factor model instead of the proposed seven-factor model. Consciousness, Maturity and Control (CoMaCt). CFA of FI factor maintained one-factor model and also valid in term of construct. Conclusion: The modified USMEQ-i, which consisted of separate EI and FI models, was proven to have valid measurement models and reliable constructs. It is considered to be suitable for use among applicants to medical degree program in USM. However, its use as medical student selection tool may require further research, especially how predictive USMEQ-i scores with real performance of medical students, generalizability of the inventory and its stability over time.
Introduction: USMaP-i is an English, 66-item self-administered inventory, consisting of personality
(60 items, 5 factors) and faking (one factor) components, which was mainly developed to measure
personality traits among Malaysian students based on local cultures and values. The personality
component was based on the Big Five dimensions as suggested by numerous personality researchers.
Previous exploratory studies showed promising validity, reliability and stability of USMaP-i.
Objective: To provide further validity evidence of USMaP-i for use among medical degree program
applicants by confirmatory factor analysis (CFA). Methods: Data were collected as a part of screening
of medical degree program applicants for year 2010–2013 intakes in Universiti Sains Malaysia
(USM), of which 657 cases were suitable for analyses following a data screening measures. CFA was
performed by bootstrap maximum likelihood estimation due to non-normality of items at multivariate
level. Results: Although the revised five-factor model of personality showed good model fit (X2(df) =
144.36(55), P-value < 0.001; CFI = .944, TLI = .921; RMSEA = .050; SRMR = .032, Bollen-Stine
bootstrap P-value = 0.004), the reliability of the factors is very poor (composite reliabilities (CR) =
.483 to .650). In contrast, the unidimensional faking component exhibited good model fit (X2(df)
= 14.15(5), P-value = 0.015; CFI = .984, TLI = .968; RMSEA = .053; SRMR = .011, BollenStine
bootstrap P-value = 0.068) and factor reliability (CR = 0.731). Conclusion: The personality
component should be revised and revalidated due to poor reliability, despite showing good model fit.
In contrast, the faking component showed good model fit and reliability. Further validation studies are
recommended before its use among medical degree program applicants.
Many researchers have emphasized the importance of teaching stress management and self-care skills to medical students as they are vulnerable to develop psychological health problems. The researchers designed a 4-hour intervention based on the DEAL model to address these problems. This study aimed to determine outcomes of the DEAL-based intervention on medical students’ stress, anxiety and depression symptoms. Methods: A randomized controlled trial study was conducted on 171 medical students. Their stress, anxiety and depression symptoms were measured by the 21-item Depression Anxiety Stress Scale at five intervals; at 2 weeks before the intervention, and at 1 week, 8 weeks, 16 weeks and 32 weeks after the intervention. The mixed model ANCOVA was applied to determine the effect of the intervention on the participants’ psychological health at five intervals. Results: A total of 153 medical students (intervention = 73 and control = 80) completed this study. Results showed that the intervention group experienced significantly lower stress and depression symptoms than the control group. Although anxiety scores are consistently lower in the intervention group, no significant differences between groups were found. Conclusion: These results support the favourable outcomes of the intervention on psychological health of medical students. It is a promising intervention to be considered by medical schools as it consumes minimal amount of time, money, training and man power as well can be implemented easily.
To ensure the reliability of manual blood pressure (BP) readings in a clinical trial, sources of error due to measurement must be reduced as much as possible. Apart from following standard procedure for BP measurement and ensuring good equipments, the measurement errors that come from the assessors themselves should be assessed. Objective: To demonstrate the use of two-way random effects, interactions absent, absolute agreement (Type A), single measures (Type 1) intraclass correlation coefficient (ICC) in the assessment of reliability of manual BP readings among assessors involved in a clinical trial using manual BP measurement, by using an interrater reliability study conducted by the authors as an example study. Methods: The steps involved in obtaining ICC in the study were discussed. Sample size given the number of assessors in the study was calculated. BP was measured using regularly maintained mercury sphygnomanometers, following recommendations by Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) for BP measurement in office setting. The outcomes were systolic and diastolic BP readings. A type of ICC, two-way random effects, interactions absent, absolute agreement (Type A), single measures (Type 1) ICC was chosen for the analysis and specifically discussed. Pre-requisite assumptions for ICC were meticulously checked and described. The interrater reliability for systolic and diastolic BP readings as expressed by ICC (single measure) were presented with confidence interval (CI). The ICCs obtained in the example study were discussed and concluded. The flaws of the study were also criticised. Results: The interrater reliability for systolic and diastolic BP measurements as expressed by ICC (single measure) were 0.87 (95% confidence interval [CI] 0.722, 0.956) and 0.77 (95% CI 0.560, 0.918) respectively. Conclusion: We demonstrated the steps required to obtain ICC. Since the use of manual BP measurement using mercury sphygmomanometer is still considered as gold standard of BP measurement, it is important that studies in which the BP outcome is measured using such method conduct interrater reliability studies properly.
Objective: To determine the validity and reliability of Incontinence Praying Ability (I-PA) among
Muslim childbearing-aged women. Methods: A cross sectional study was conducted among Muslim
women under childbearing age attended clinics in a university teaching hospital. Two measures were
used in the present study and there were I-PA and Incontinence Quality of Life (I-QoL). I-PA was
developed in Malay language and its construct validity had not been explored. The questionnaires
were handed to the Muslim women during their visit to the clinics in Hospital Universiti Sains
Malaysia. Exploratory Factor Analysis (EFA) was conducted to determine the construct validity
and the Cronbach’s alpha was used to examine the internal consistency reliability of I-PA. Pearson
correlation was used to examine the correlation between I-PA and the subscales of I-QoL. Validity was
further supported if both scales were significantly correlated. Results: A total of 162 Muslim women
completed and returned the questionnaires to the researchers. The mean age of participants was 32.4
(SD = 5.87). Based on EFA result, all the 10 items of I-PA were remained in the model under one
factor and no item deletion was required. The factor loadings were ranged from 0.70 to 0.91. The
internal consistency of I-PA was satisfactory with Cronbach’s Alpha of 0.94. There were significant
correlations between I-PA and I-QoL’s subscales, ranged from 0.64 to 0.71. Conclusion: I-PA was
considered a valid and reliable questionnaire measuring incontinence quality of life in the aspect of
praying ability or spirituality among Muslim childbearing-aged women.
Unintentional injuries cause huge economic and social burden for the country. To further prevent unintentional injury by different age groups, it is crucial to identify the recent pattern of paediatric mortality. For a start, this study included a retrospective record review of 334 paediatric trauma patients (0-18 years) who were hospitalized due to unintentional injuries. The patient’s medical records from the period 2007 to 2010 were obtained from the National Trauma Database (NTrD). The patients were categorized into
A sample of 204 handicapped children below 12 years of age consisting of 121(59.3%) males and 83 (40.7%) females who were classified into various types of mental and physical handicaps, were surveyed in April and May 1996. The majority of those with mental handicaps were Down Syndrome while those with cerebral palsy were the mostfrequent cause of physical handicaps. A structured questionnaire was used for interviewing the children parents to evaluate their attitude towards their handicapped children. The majority of the parents expressed their opinions that having handicapped children was not a burden to them although these children had to be given more attention. However, a significant minority felt that the child would be afinancial burden to the family and that he/she would restrict the social life of the family. The majority of the children were sent to school, as parents felt it was their duty to do so. For those children not attending school, the majority of parents felt that the children would not benefit by going. The others could not do so because offinancial constraints or because of the distance between home and school. For these children, provid-ing hostel facilities in a boarding school could be the answer. This study shows that parental love and support plays a major role in ensuring optimal growth and development of a handicapped child
This study was conducted to identify factors which influence the safety of children in day-care centres and home-based nurseries in the state of Kelantan. A total of 20 registered day care centres (DCC) and 40 home-based nurseries (IIBN) identified in 3 districts in the state were included in the study. Problems identified which could affect the safety of children cared-for in these nurseries were inadequate and unsafe facilities, inappropriate location of nurseries, lack of trained workers and their ignorance of necessary safety measures.
BACKGROUND: Uric acid is a final breakdown product of purine catabolism in humans. It's a potent antioxidant and can also act as a pro-oxidant that induces oxidative stress on the vascular endothelial cells, thus mediating progression of diabetic related diseases. Various epidemiological and experimental evidence suggest that uric acid has a role in the etiology of type 2 diabetes mellitus. We conducted a cross-sectional study to evaluate the correlation of retinal nerve fibre layer (RNFL) and macular thickness with serum uric acid in type 2 diabetic patients.
METHODS: A cross-sectional study was conducted in the Eye Clinic, Hospital Universiti Sains Malaysia, Kelantan between the period of August 2013 till July 2015 involving type 2 diabetes mellitus patients with no diabetic retinopathy and with non-proliferative diabetic retinopathy (NPDR). An evaluation for RNFL and macular thickness was measured using Spectralis Heidelberg optical coherence tomography. Six ml of venous blood was taken for the measurement of serum uric acid and glycosylated haemoglobin (HbA1C).
RESULTS: A total of 180 diabetic patients were recruited (90 patients with no diabetic retinopathy and 90 patients with NPDR) into the study. The mean level of serum uric acid for both the groups was within normal range and there was no significance difference between the two groups. Based on gender, both male and female gender showed significantly higher level of mean serum uric acid in no diabetic retinopathy group (p = 0.004 respectively). The mean serum uric acid was significantly higher in patient with HbA1C
