    BACKGROUND AND PURPOSE: Training pharmacy students in infectious diseases (ID) is important to enable them to participate in antibiotic stewardship programs. This study evaluated knowledge and self-confidence regarding antibiotic resistance, appropriate antibiotic therapy, and antibiotic stewardship among final year pharmacy undergraduate students.

    METHODS: A cross-sectional electronic survey was conducted at universities in Indonesia, Malaysia, and Pakistan. A 59-item survey was administered between October 2017 and December 2017.

    FINDINGS: The survey was completed by 211 students (response rate 77.8%). The mean knowledge score for antibiotic resistance, appropriate antibiotic therapy, and antibiotic stewardship was 5.6 ± 1.5, 4.7 ± 1.8 (maximum scores 10.0) and 3.1 ± 1.4 (maximum score 5.0), respectively. Significant variations were noted among the schools. There was poor awareness about the consequences of antibiotic resistance and cases with no need for an antibiotic. The knowledge of antibiotic resistance was higher among male respondents (6.1 vs. 5.4) and those who had attended antibiotic resistance (5.7 vs. 5.2) and antibiotic therapy (5.8 vs. 4.9) courses (p

    Mid-facial defect is one of the most disfiguring and impairing defects. A design of prosthesis that is aesthetic and stable can be precious to a patient who has lost part of his face due to surgical excision. Prosthesis can restore the patients' self-esteem and confidence, which affects the patients and their life style. The aim of this case report is to describe a technique of mid-facial silicone prosthesis fabrication.

    Sex differences in educational encouragement and their predictiveness of academic achievement were examined among 442 secondary school students (M age = 13.2 yr., SD = 1.9). Education-related encouragement received from mothers, fathers, friends, and teachers was assessed. Academic achievement was based on student self-reports and grades. Female adolescents reported receiving statistically significantly more educational encouragement from their mothers, fathers, friends, and teachers than did male adolescents. In regression, sex and educational encouragement from parents, friends, and teachers were found to be significant predictors of academic achievement.

    The Ministry of Higher Education in Malaysia has called for the implementation of a soft skills module in all public universities in Malaysia. In response to this and as part of curriculum development efforts for a new integrated program for 2011, a study was undertaken to improve the University of Malaya (UM) Faculty of Dentistry's communication skills course. One of the study objectives was to investigate dental students' attitudes towards communication skills learning and the association between their attitudes and demographic and education-related characteristics. A cross-sectional survey--using a self-administered twenty-four-item adapted Communication Skills Attitude Scale (CSAS) that contained both positive (PAS) and negative (NAS) attitude subscales--was carried out targeting all final-year dental students at the UM and the Universiti Kebangsaan Malaysia (UKM). A total of 148 students completed the survey, yielding a response rate of 88.1 percent. Overall, UKM students had significantly more positive attitudes towards communication skills learning (PAS score: mean=48.69, SD=4.48, p<0.001) than UM students (mean=46.03, SD=4.22). There was no statistically significant difference in negative attitudes between the two groups. UKM students with more positive attitudes tended to be female (p<0.05). UM students with more negative attitudes perceived themselves as poor communicators (p<0.05), and UKM students with more negative attitudes tended to have poor English proficiency (p<0.05). This study found that both UM and UKM final-year dental students have positive and negative attitudes towards learning communication skills. These attitudes were significantly associated with certain background and education-related attributes. Outcomes of this study served as a valuable guide in strengthening the communication skills course for the UM's new, integrated dental curriculum.

    A longitudinal study evaluated the success of a contact-based nation-building intervention (the Malaysian National Service Programme) in promoting various facets of national unity. The study assessed how post-test measures of quality of intergroup contact, outgroup evaluations, and levels of identification changed compared to their respective pre-test levels, for both National Service and control group participants. The intervention did not lead to a worsening of any of the constructs related to intergroup relations, which is noteworthy given the novelty for many participants of mixing in a multi-ethnic setting. Furthermore, all rater groups (Malays, Chinese, and Indians) maintained their ethnic identity, even in the presence of high levels of national identity, which we discuss with respect to past research on the effects of positive intergroup contact on minority group identification. However, the changes associated with the intervention yielded only small effect sizes, and, on the whole, National Service participants did not show significantly greater improvement than that experienced by control participants. We discuss the value of intergroup contact in this novel setting, considering various features of this programme that may have limited its effectiveness and discuss how such interventions can more successfully meet their goals.

    This article investigates the influence of perceived health status on the daily activity participation of older Malaysians. Data from the Survey on Perceptions of Needs and Problems of the Elderly, which was conducted in 1999, were used. The negative binomial regression results show that older persons with good perceived health status reported more varieties of daily activity participation, especially among the uneducated and those with below-average self-esteem. The multinomial logistic regression model suggests that older persons with good perceived health status tended to engage daily in paid work only or with leisure activities, whereas those perceived to have poor health were more likely to engage in leisure activities only or leisure and family role activities. Promotion of a healthy lifestyle at a younger age encourages every person to monitor and take responsibility for their own health, which is a necessary strategy to ensure active participation at an older age, and thus improve their well-being.

    This study was conducted to measure the prevalence of cigarette smoking and to determine the individual, family, and environmental factors associated with smoking among young urban women. A cross-sectional study through self-administered questionnaire was conducted on female students enrolled in private higher learning institutions in Kuala Lumpur and Selangor, Malaysia, between July and October 2005. Analysis on 408 respondents showed that current smoker prevalence rate was 18.6%. Adjusted analyses showed significant association between smoking and individual factors, which are the importance of slim image, average monthly allowance, and car ownership. For family factors, analyses showed significant association between smoking and parental marital status and smoking status of male siblings. Strong associations were seen between female smoking and environmental factors, such as having more smoker friends, having smokers as best friends, keeping cigarette-brand items, being offered free cigarette, and perceiving female smoking as normal. The identified risk factors could be used to develop more effective prevention programs to overcome smoking among young urban women.

    Hearing impairment is one of the most important health problems of the elderly above 60. Very often it leads to verbal communication difficulty and without treatment it can cause serious psychological and social complications such as depression and social isolation. Prebyscusis remains a leading cause of sensorineural deafness in the elderly. Elderly patient must be encouraged to seek proper hearing assessment if they face hearing difficulty. Active screening by health care workers and patient self-evaluation by answering a simple list of screening questions are possible for early detection and treatment of hearing loss in the elderly. Although hearing loss in the elderly may not have a cure, early rehabilitation helps to restore better quality of life if the problem is detected early.

    Recent evidence suggests that suicidal ideation is increased among university students, it is essential to increase our knowledge concerning the etiology of suicidal ideation among university students. This study was conducted to examine the relationships between problem-solving skills appraisal, hardiness, and suicidal ideation among university students. In addition, this study was conducted to examine problem-solving skills appraisal (including the three components of problem-solving confidence, approach-avoidance style, and personal control of emotion) as a potential mediator between hardiness and suicidal ideation.

    The present paper is the third and concluding part of a study of the secondary school population of two of Malaysia's thirteen states, Penang and Selangor. Since completion of the two earlier papers, the research team has investigated the pattern and nature of drug use among the equivalent population in a third state, Kelantan, and has again found essentially the same pattern of results: youthful drug use is most clearly related to precocious self-assertion, and a set of beliefs and attitudes about drugs and drug taking, and is largely unrelated to indicators of social deprivation or personal problems. The significance of this repeated finding in Kelantan is that, in this much more rural and traditional state, adult and established patterns of drug use had historically differed considerably from those found in the two more urban and cosmopolitan states of Penang and Selangor. Our findings indicate that the new pattern of drug use by youth has transcended the older cultural differences between the states, and is in turn explained by a more universally familiar set of characteristics in adolescent development.

    PMID: 27792885 DOI: 10.1016/j.eplepsyres.2016.10.003
    PURPOSE: People with epilepsy (PWE) are negatively prejudiced in their ability to work. This study aimed to examine demographic, clinical and psychological factors associated with employability in PWE.

    METHODS: This study recruited epilepsy patients from a neurology clinic in Malaysia. Employability was measured using employment ratio, with a ratio ≥90% (ER90) classified as high employability. Basic demographic data such as age, gender, marital status, religion, education level and household income was collected. Clinical measures consisted of age of seizure onset, seizure frequency, type of epilepsy, aura, polytherapy, nocturnal seizures and seizure control. Psychological measures included Work Self-Determination Index (WSDI), Rosenberg Self-Esteem Scale (SES), and Multidimensional Scale of Perceived Social Support (MSPSS).

    RESULTS: Of 146 PWE, 64.4% had high employability. The participants were predominantly female (52%), Chinese (50.7%), single (50%), having tertiary education (55.5%) and focal epilepsy (72.6%). Clinically, only type of epilepsy was significantly correlated to employability of PWE. Employability of PWE was associated with ability to work (indicated by education level, work performance affected by seizures, ability to travel independently and ability to cope with stress at work) and family overprotection. The high employability group was found to have lower self-perceived stigma (ESS), higher self-determined motivation (WSDI), self-esteem (SES) and perceived social support (MSPSS), than the low employability group. Logistic regression analysis showed that tertiary education level (AOR 3.42, CI: 1.46-8.00), higher self-determination (WSDI, AOR 1.09, CI: 1.012-1.17), lower family overprotection (AOR 0.76, CI: 0.61-0.95), and generalised epilepsy (AOR 4.17, CI: 1.37-12.70) were significant predictors for higher employability in PWE.

    CONCLUSION: Ability to work (education level), clinical factor (type of epilepsy) and psychological factor (self-determined motivation and family overprotection) were important factors affecting employability in PWE.

    PURPOSE: The objective of this study was to investigate the relationships between high-risk behaviours and personal and family factors among adolescents in Malaysia.

    METHODS: A nationwide data set was examined for this secondary data analysis. The dependent variable was the degree of risk, which was measured based on the number of high-risk behaviours in which adolescents participated. Age, gender, ethnicity, self-rated academic performance, family size, parental marital status and parental academic attainment were included as independent variables. Analyses stratified by educational level were conducted. Odds ratios (ORs) were calculated using ordered logit.

    RESULTS: The most common high-risk behaviour among Malaysian adolescents was physical inactivity (35.97%), followed by smoking (13.27%) and alcohol consumption (4.45%). The majority of adolescents had low risks (52.93%), while only a small proportion had high risks (6.08%). Older age was associated with increased odds of having high risks (OR: 1.26). Male adolescents had higher odds of being in a high-risk category compared to female adolescents (OR: 1.28). Compared to Malays, Chinese adolescents had higher odds of being in a high-risk category (OR: 1.71), whereas Indian adolescents had lower odds (OR: 0.65). Excellent academic performance was associated with reduced odds of participating in high-risk behaviours (OR: 0.41).

    CONCLUSION: Personal factors are important determinants of high-risk behaviours. This study provides a better understanding of those adolescent groups that are at greater risk.

    PRACTICAL IMPLICATIONS: An intervention directed towards reducing participation in high-risk behaviours among adolescents who have both poor academic performance and less-educated parents may yield promising outcomes.

    Many factors contribute to the reluctance towards blood donation, but available studies done in Malaysia involving University students does not reflect the knowledge of the public in general. The objective of this study is to determine knowledge, attitude practice towards blood donation among the Sandakan population. A cross-sectional study was employed using an adapted 29-item structured validated questionnaire available in English and Bahasa, consisting of subject’s demography, questions regarding knowledge, attitude, and perception of blood donation. Convenient random sampling was done within the hospital compound, 79 healthy adults consented, and their data were used for the final data analysis, yielding an excellent internal consistency (Cronbach’s α coefficient = 0.816). Out of all, 74.7% of the respondents had a high level of knowledge, and independent t-tests showed that those who were not married, had tertiary education, donated blood in the past, had a statistically significant higher level of knowledge and 96.2% of respondents have a positive attitude. Some donors (40.6%) donated blood for moral satisfaction, and only a quarter (25%) experienced adverse events. Fear of pain, needle, fainting was the highest reason for reluctance in blood donation (36.2% of non-donors), followed by self-perception of being medically unfit to donate (31.9% of non-donors). Even though the sampled population in Sandakan showed an adequate level of knowledge as well as a positive attitude towards blood donation, blood product shortage is still present. This study may contribute by serving as an educational platform for awareness and education to improve the number of blood donors.

    Context: The attitude of healthcare professionals and social supports give big influence toward self-esteem of physically disabled people.

    Aims: To explore how impairments could affect the self-esteem of physically disabled people and how healthcare professionals and social support boost their self-esteem.

    Materials and Methods: This study was conducted qualitatively whereby face-to-face interviews were conducted among 10 participants with physical disabilities. Participants were recruited from two rehabilitation centres in Kuantan, namely Community-based rehabilitation and rehabilitation, occupational therapy, and physiotherapy of public hospital in Kuantan. Interviews were conducted using the developed interview guide that explored on the disabled peoples' self-esteem and motivation, feelings toward attitude of the healthcare professionals, and satisfaction toward the physical, services, and social support from the healthcare professionals. Thematic analysis was done to identify the themes emerged from the interview transcripts.

    Results: Five males and five females with age ranging from 31 to 58 years were interviewed. Five are still working or studying post impairments. Participants claimed being low self-esteem resulted from negative perception from the society, issue of rejection, being discriminated, and difficulty in getting support from the society. Most of the participants asserted that they gained their motivation and self-esteem due to the continuous support from various groups, such as their spouses, family members, colleagues, employers, and healthcare professionals.

    Conclusions: Despite heavy workload and stressful working environment, positive attitude showed by the healthcare professionals is highly praised. Hence, this will indirectly improve the self-esteem, motivation, and rehabilitation progress of physically disabled people.

    Self-awareness of poorly arranged teeth can influence the quality of life. This study aimed to report the impacts of self-perceived malocclusion in young adults and the association between demographic characteristics and oral health related quality of life (OHRQoL). In this cross-sectional study, six-hundred-forty-three subjects from Selangor, Malaysia selected using a multistage sampling technique answered the Psychosocial Impact of Dental Aesthetics (PIDA) questionnaire and self-rated their dental appearance using the Aesthetic Component of the Index of Orthodontic Treatment Need. Data were analyzed using multifactorial ANOVA to identify the association between demographic characteristics and total PIDA score. Five-hundred-twenty-four subjects (81.5%) completed the questionnaires. Overall, 87.8% had impacts on their OHRQoL. Psychological impact was the most impacted domain (75.8%), followed by dental self-confidence (59.4%), social impact (48.9%) and aesthetic concern (22.1%). 16.8% reported significant impacts on all domains. Their mean PIDA score was 36.3 (SD 17.1). Prevalence, extent and severity of impacts were higher amongst those with self-perceived malocclusion. Gender, ethnicity, and self-perceived malocclusion status were associated with PIDA score (p < 0.05). Sub-urban and rural females had significantly higher PIDA scores than sub-urban and rural males. In conclusion, majority of Malaysian young adults especially those with self-perceived malocclusion were impacted by their dental aesthetics.

    BACKGROUND: Atopic eczema (AE) is a common relapsing inflammatory skin disease in children which is often associated with chronicity and poor quality of life. Unlike atopic asthma, control of AE is seldom assessed in therapeutics.

    AIM: To investigate the utility of a Traffic Light Control (TLC) system as a measurement/assessment of self-perceived eczema control.

    METHODS: This is a prospectively study of all Chinese children (aged 6 to 18 years old) with eczema attending the paediatric dermatology clinic of a tertiary hospital from Jan to June 2020. Eczema control, eczema severity, quality of life and biophysical skin condition of consecutive patients at the paediatric dermatology clinic of a teaching hospital were evaluated with the validated Chinese versions of Depressive, Anxiety, Stress Scales (DASS-21), Patient Oriented Eczema Measure (POEM), transepidermal water loss (TEWL), and stratum corneum skin hydration (SH), respectively. With a visual TLC analogy, patients were asked if their eczema is under control (green light), worsening (yellow) or in flare-up (red light).

    RESULTS: Among AE patients (n = 36), self-perceived TLC as green (under control), amber (worsening) and red (flare up) reflected acute and chronic severity (SCORAD, NESS, POEM) and quality of life (CDLQI) (p< 0.0001), but not SH, TEWL or Depression, anxiety and stress.

    CONCLUSIONS: Eczema control can be semi-quantified with a child-friendly TLC self-assessment system. AE patients reporting worse eczema control have worse acute and chronic eczema severity, more impairment of quality of life; but not the psychologic symptoms of depression, anxiety and stress or skin hydration or transepidermal water loss. TLC can be linked to an eczema action plan to guide patient management.

    Language learning is an emerging research area where researchers have done significant contributions by incorporating technological assistantship (i.e., computer- and mobile-assistant learning). However, it has been revealed from the recent empirical studies that little attention is given on grammar learning with the proper instructional materials design and the motivational framework for designing an efficient mobile-assisted grammar learning tool. This paper hence, reports a preliminary study that investigated learner motivation when a mobile-assisted tool for tense learning was used. This study applied the Attention-Relevance-Confidence-Satisfaction (ARCS) model. It was hypothesized that with the use of the designed mobile- assisted tense learning tool students would be motivated to learn grammar (English tense). In addition, with the increase of motivation, performance outcome in paper- based test would also be improved. With the purpose to investigate the impact of the tool, a sequential mixed-method research design was employed with the use of three research instruments; Instructional Materials Motivation Survey (IMMS), a paper-based test and an interview protocol using a semi-structured interview. Participants were 115 undergraduate students, who were enrolled in a remedial English course. The findings showed that with the effective design of instructional materials, students were motivated to learn grammar, where they were positive at improving their attitude towards learning (male 86%, female 80%). The IMMS findings revealed that students' motivation increased after using the tool. Moreover, students improved their performance level that was revealed from the outcome of paper-based instrument. Therefore, it is confirmed that the study contributed to designing an effective multimedia based instructions for a mobile-assisted tool that increased learners' motivational attitude which resulted in an improved learning performance.

    AIM: This study aimed to evaluate the oral health-related quality of life (OHRQoL) among older persons in Malaysia and its associations with sociodemographic and self-perception towards general health as well as oral health.

    METHODS: A cross-sectional survey among community dwelling older persons utilizing stratified cluster sampling was conducted in 2018. Well-trained interviewers conducted a face-to-face interview with older persons aged ≥60 years to collect information on participants' sociodemographic characteristics, self-perception on general as well as oral health using the Geriatric Oral Health Assessment Index (GOHAI). Multivariate analysis of the data collected was performed using SPSS version 23.

    RESULTS: Overall, the GOHAI mean ± SD score for older persons in Malaysia was 51.83 ± 7.98, which was an average of fair mean (P self-rated oral health (48.34 ± 8.96) or poor self-rated general health (47.13 ± 8.93) had poor mean OHRQoL (P self-perceived unhealthy oral health (aOR: 3.83 [3.19, 4.59]) were significantly associated with higher odds of having poor OHRQoL.

    CONCLUSIONS: The estimated OHRQoL of older persons in Malaysia is rated as fair, with minimum association contributed by the sociodemographic factors, but with a significant influence by self-rated oral and general health. Self-perception of health can be used as a good indicator to estimate the OHRQoL. Geriatr Gerontol Int 2020; 20: 57-62.

    Overweight during adolescence has many psychological consequences and low self·esteem is the immediate detrimental effect observed. Adolescents with low self»esteem are at risk for many emotional and behavioural disorders while high self-esteem adolescents experience an incremental improvement in their quality of life. The objective of this study was to compare seh'-esteem between overweight and non-overweight Malay adolescents in Kota Bharu, Kelantan. A cross-sectional study was conducted between January to ]une 2005 among 1364 students selected from ten co-educational government secondary schools in Kota Bharu using stratified multistage cluster sampling. A set of guided self-administered questionnaire which included a Malaysian version of Rosenberg Self-Esteem Scale and Body Mass Index measurement was used. Data was entered using SPSS 12.0 and analysed using STATA 8. O. The prevalence of overweight among secondary school students in Kota Bharu was 12.5% and there was no significant difference in self-esteem between overweight and non-overweight students. However, the findings may not be generalized to out-of-school youth and other ethnic groups in this country. Infomation on other modifers, such as parental acceptance or lack of concern regarding the child’ obesity was not elicited in this study. It is an important protective factor for self-esteem and need to be included in future studies.

    BACKGROUND: The Malay version of the Psychosocial Impact of Dental Aesthetics Questionnaire has been validated for use by Malaysian adolescents. Although Malay is their national language, English is widely used as the lingua franca among Malaysians of different ethnicities. This study aimed to validate an English version of the PIDAQ adapted for use by Malaysian adolescents to optimize data capture from adolescents who prefer English as the medium for communication.

    METHODS: The published English version of PIDAQ was pilot tested on 12- to 17-year-old adolescents, resulting in a few modifications to suit the Malaysian variety of English. Psychometric properties were tested on 393 adolescents who attended orthodontic practices and selected schools. Malocclusion was assessed using the Malocclusion Index, an aggregation of Perception of Occlusion Scale and the Aesthetic Component of the Index of Orthodontic Treatment Need, by the subjects (MI-S) and investigators (MI-D). Data were analysed for internal consistency and age-associated invariance, discriminant, construct and criterion validities, reproducibility and floor and ceiling effects using AMOS v.20 and SPSS v.20.

    RESULTS: The item Don't like own teeth on video of the Aesthetic Concern (AC) subscale was not relevant to a large proportion of participants (11.7%). Therefore, it was removed and the Malaysian English PIDAQ was analysed based on 22 items instead of 23 items. Confirmatory factor analysis showed good fit statistics (comparative fit index: 0.902, root-mean-square error of approximation: 0.066). Internal consistency was good for the Dental Self-Confidence, Social Impact and Psychological Impact subscales (Cronbach's alpha: 0.70-0.95) but lower (0.52-0.62) though acceptable for the AC subscale as it consisted of only 2 items. The reproducibility test was acceptable (intra-class correlations: 0.53-0.78). For all PIDAQ subscales, the MI-S and MI-D scores of those with severe malocclusion differed significantly from those with no or slight malocclusion. There were significant associations between the PIDAQ subscales with ranking of perceived dental appearance, need for braces and impact of malocclusion on daily activities. There were no floor or ceiling effects.

    CONCLUSION: The adapted Malaysian English PIDAQ demonstrated adequate psychometric properties that are valid and reliable for assessment of psychological impacts of dental aesthetics among Malaysian adolescents.
