  • Article: Psychometric properties of the Malay version of the Breast Module (BR23).
    N Yusoff, W Y Low, C H Yip
    [show abstract] [hide abstract]
    ABSTRACT: The Breast Module (BR23) is increasingly being used worldwide in breast cancer research. This study evaluates the appropriateness of the translated version (i.e. BR23-Malay version) as a useful tool for the Malaysian population who could understand Malay, and examines the reliability and validity of the BR23-Malay version. This was a prospective study involving 68 Malaysian women who could understand Malay very well. They answered the BR23-Malay version at two evaluation points--three and ten weeks following surgery for breast cancer. Internal consistency, test-retest intraclass correlation coefficients (ICC), effect size index, sensitivity and discriminity of the scale were calculated. Internal consistencies were acceptable for the functional domains (0.87 for body image; 0.84 for sexual functioning) and symptomatology domains (0.82 for systemic therapy side effect; 0.82 for breast symptoms; 0.70 for arm symptoms). Test-retest ICC ranged from 0.26 to 1.00. Sensitivity of the scale was observed in all domains except sexual functioning. The Malay version of BR23 is a suitable tool to measure the functional and symptomatology domains of women diagnosed with breast cancer.

  • Article: Somatisation disorder and its associated factors in multiethnic primary care clinic attenders.
    [show abstract] [hide abstract]
    ABSTRACT: Somatisation disorder (SD) has been reported as common in all ethnic groups, but the estimates of its prevalence have varied and the evidence for its associated factors has been inconsistent. This study seeks to determine the prevalence of SD and its associated factors in multiethnic primary care clinic attenders. This cross-sectional study was on clinic attenders aged 18 years and above at three urban primary care clinics in Malaysia. The operational definition of SD was based on ICD-10 criteria for SD for research, frequent attendance, and excluded moderate to severe anxiety and depression. The instruments used were the ICD-10 symptom list, the Hospital Anxiety and Depression Scale, a semi-structured questionnaire, and SF-36. We recruited 1,763 patients (response rate 63.8%). The mean age of respondents was 44.7 ± 15.8 years, 807 (45.8%) were male; there were 35.3% Malay, 30.1% Chinese and 34.6% Indian. SD prevalence was 3.7%; the prevalence in Malay was 5.8%, Indian 3.0% and Chinese 2.1%. Significant associations were found between SD prevalence and ethnicity, family history of alcoholism, blue-collar workers and the physical component summary (PCS) score of SF-36. Multivariate analysis showed that SD predictors were Malay ethnicity (OR 2.7, 95% CI 1.6, 4.6), blue-collar worker (OR 2.0, 95% CI 1.2, 3.5) and impaired PCS score of SF-36 (OR 0.92, 95% CI 0.90, 0.95). The prevalence of SD was relatively uncommon with the stringent operational criteria used. SD preponderance in blue-collar workers may be attributable to secondary gain from getting sickness certificates and being paid for time off work.

    Article: Reliability and validity of the Brief COPE Scale (English version) among women with breast cancer undergoing treatment of adjuvant chemotherapy: a Malaysian study.
    N Yusoff, W Y Low, C H Yip
    [show abstract] [hide abstract]
    ABSTRACT: This paper validates the Brief COPE Scale in Malaysian women with breast cancer. Test-retest evaluation was undertaken at two/three weeks and ten weeks following surgery. Internal consistencies ranged from 0.25 to 1.00. Meanwhile, the Intraclass Correlation Coefficient (ICC) ranged from 0.05 to 1.00. Sensitivity of the scale was indicated by the mean differences as observed in most of the domains with Effect Size Index (ESI) ranged from 0 to 0.53. Significant differences between mastectomy and lumpectomy were observed for Active coping, Planning and Acceptance. Brief COPE Scale showed fairly good reliability and validity.

  • Article: Development and validation of the osteoporosis patient satisfaction questionnaire (OPSQ).
    [show abstract] [hide abstract]
    ABSTRACT: To develop and validate the Osteoporosis Patient Satisfaction Questionnaire (OPSQ) and to assess the opinion of postmenopausal osteoporotic women towards pharmaceutical care. A 16-item instrument was designed. Each response consists of a five-point Likert-like scale with higher scores indicating greater satisfaction. The face and content validity was established via consultation with an endocrinologist and three pharmacists as well as feedback from participants in a preliminary study. Postmenopausal osteoporotic women taking bisphosphonates were recruited and randomly allocated to the intervention (n=90) and control groups (n=90). Pharmaceutical care was provided at month 2 to the intervention group while the control group received standard pharmacy services. The OPSQ was administered at month 6 (end of the intervention period), to assess patients' satisfaction. Factor analysis was performed using varimax rotation. Internal reliability was established using Cronbach's alpha. Construct validity was performed by using the Mann-Whitney U test. The internal reliability of the OPSQ produced a Cronbach's alpha of 0.86. Factor analysis identified one component in the OPSQ, which measured patient satisfaction. The intervention group showed significantly better overall OPSQ score than the control group (91.89+/-7.22% versus 84.32+/-7.48%, p<0.001). This indicates that the OPSQ was able to differentiate between participants who received pharmaceutical care from those who did not. The 16-item OPSQ developed in this study has high internal reliability and is a valid instrument for assessing osteoporotic women's satisfaction with pharmaceutical care service in Malaysia.

    Article: Mental health knowledge, attitude and help-seeking tendency: a Malaysian context.
    R Yeap, W Y Low
    [show abstract] [hide abstract]
    ABSTRACT: This study examines the general public's knowledge of mental health and explores effective tools to promote good mental health through a household survey of a representative sample of the Malaysian population residing in Klang Valley, Malaysia. A total of 587 respondents, aged 18 years and older, responded to a series of questions in relation to mental health issues. Respondents were requested to specify how they learned about the information. Following that, an attitude scale was presented to the participants, and they were requested to rate how much they agreed to the statements. The findings indicated that the majority of the respondents did not have good knowledge of mental health. However, all respondents displayed a neutral attitude towards mental health issues. It was found that ethnic background, religion, educational level and residential location were the few demographic characteristics found to be significantly related to either the respondent's knowledge or attitude towards mental health issues. With regard to seeking help, while the respondents' ethnic background influenced their decisions, younger respondents and respondents with better attitude towards mental health were more willing to seek help. This study has implications for promoting the understanding of the general mental well-being as well as the importance of seeking help for mental health in the local population. Steps should be taken to improve the public's understanding of, and attitude towards mental health. These include the presentation of a positive image and the dissemination of accurate information by the mass media, the primary source for information on mental health.

    Article: Knowledge and awareness of cervical cancer and screening among Malaysian women who have never had a Pap smear: a qualitative study.
    [show abstract] [hide abstract]
    ABSTRACT: Cervical cancer is one of the commonest cancers in women worldwide. Despite the existence of effective screening using Pap smear, the uptake of screening is poor. A qualitative study was undertaken using face-to-face in-depth interviews to investigate knowledge, attitudes and beliefs on cervical cancer screening of Malaysian women. In-depth interviews were conducted with 20 Malaysian women aged 21-56 years and who have never had a Pap smear test, with the aim to explore their knowledge and awareness of cervical cancer and its screening. A lack of knowledge on cervical cancer and the Pap smear test was found among the respondents. Many women did not have a clear understanding of the meaning of an abnormal cervical smear and the need for the early detection of cervical cancer. Many believe the purpose of the Pap smear test is to detect existing cervical cancer, leading to the belief that Pap smear screening is not required because the respondents had no symptoms. Despite considerable awareness of a link between cervical cancer and sexual activity, as well as the role of a sexually-transmitted infection, none of the respondents had heard of the human papillomavirus. The findings highlight the importance of emphasising accurate information about cervical cancer and the purpose of Pap smear screening when designing interventions aimed at improving cervical cancer screening for Malaysian women.

  • Article: The validity and reliability of the Malaysian Osteoporosis Knowledge Tool in postmenopausal women.
    [show abstract] [hide abstract]
    ABSTRACT: To design a valid and reliable questionnaire, the Malaysian Osteoporosis Knowledge Tool (MOKT), to assess the knowledge of postmenopausal osteoporotic women in Malaysia, on osteoporosis and its treatment. A 40-item instrument was designed and tested in this study. The scores ranged from 1 to 40, which were then converted into percentage. This was administered to 88 postmenopausal osteoporotic women who were taking alendronate (patient group) and 43 pharmacists (professional group). The MOKT was administered again to the patient group after 1 month. Flesch reading ease was 57, which is satisfactory, while the mean difficulty factor+/-S.D. was 0.73+/-0.25, indicating that the MOKT is moderately easy. Internal consistency of the instrument was good with Cronbach's alpha=0.82. The test and retest scores showed no significant difference for 38 out of the 40 items, indicating that the questionnaire has achieved a stable reliability. Level of knowledge on osteoporosis and its treatment was good with a mean score+/-S.D. of 69.0+/-13.9 and 81.6+/-9.5 in the patient and professional group, respectively. The difference in knowledge scores between the two groups was statistically significant (p<0.001). In conclusion, the 40-item questionnaire (MOKT) is a reliable and valid instrument for measuring knowledge on osteoporosis in the Malaysian setting. Therefore, it can be used to identify individuals in need of educational interventions and to assess the effectiveness of education efforts as part of osteoporosis management.

  • Article: Cervical cancer screening attitudes and beliefs of Malaysian women who have never had a pap smear: a qualitative study.
    [show abstract] [hide abstract]
    ABSTRACT: Attitudes toward cervical cancer and participation in early detection and screening services are well known to be profoundly affected by cultural beliefs and norms. This study explored the attitudes and sociocultural beliefs on cervical cancer screening among Malaysian women. In this qualitative study, in-depth interviews were conducted with 20 Malaysian women, ages 21 to 56 years, who have never had a Papanicolaou (Pap) smear. Results: Respondents generally showed a lack of knowledge about cervical cancer screening using Pap smear, and the need for early detection for cervical cancer. Many believed the Pap smear was a diagnostic test for cervical cancer, and since they had no symptoms, they did not go for Pap screening. Other main reasons for not doing the screening included lack of awareness of Pap smear indications and benefits, perceived low susceptibility to cervical cancer, and embarrassment. Other reasons for not being screened were related to fear of pain, misconceptions about cervical cancer, fatalistic attitude, and undervaluation of own health needs versus those of the family. Women need to be educated about the benefits of cervical cancer screening. Health education, counseling, outreach programs, and community-based interventions are needed to improve the uptake of Pap smear in Malaysia.

    Article: Perceived barriers to self-management in Malaysian women with breast cancer.
    S Y Loh, T Packer, C H Yip, W Y Low
    [show abstract] [hide abstract]
    ABSTRACT: Naturalistic inquiry using focus group interviews was undertaken to explore experiences and perceived barriers to self management in women with breast cancer. The aim was to identify their perceived barriers to self management to aid the development of rehabilitation programmes. Successful programmes are strongly linked to patients' perceived needs. Four focus groups consisted of 39 women, were purposively recruited. Women's needs within the three areas of medical, emotional and role management of breast cancer were explored. The main barriers were unavailability of information, inability to access services-and-support, and socioeconomic-cultural issues (entrenched myths, low-socioeconomic status, and inadequate insurance-health legislative coverage). The findings provide the critically lacking 'expert-view' of survivors, who verified the importance of the medical, emotional and role management tasks, and highlighted barriers and structural solutions. With breast cancer becoming recognised as a form of chronic illness, this study is timely.

  • Article: Factors affecting nutritional status of Malaysian primary school children.
    [show abstract] [hide abstract]
    ABSTRACT: This paper investigates the nutritional status of a randomly selected cohort of school children and the factors affecting it. This random survey was conducted in the state of Selangor, involving 1,405 primary students (aged 9-10 years from 54 national primary schools). Physical examination was carried out on all the students. Information on the students was also obtained from the parents. Blood samples were taken by using the finger pricking technique. Body mass index (BMI) was used as a measure of physical growth. The students were mainly from urban areas (82.9%). The mean age was 9.71 years and a higher proportion was females (51%). Malays constituted 83.6%, Indians 11.6% and Chinese 4.2% of the study population. The mean weight and height were 32.30 kg and 135.18 cm respectively. The mean BMI was 17.42 kg/m2, with 1.2% of the students underweight, 76.3% normal BMI, 16.3% overweight and 6.3% were obese. Nutritional status was significantly related to blood pressure, history of breast feeding, eating fast food, taking canned/bottled drinks, income and educational level of parents. Significant differences in nutritional status between sexes and locations (rural/urban) were also found. The prevalence of overweight and obese children was of concern. There is thus an urgent need for the School Health Program to periodically monitor the school children's eating habits and physical growth. Appropriate counselling on nutritional intake and physical activities should be given not only to schoolchildren but also to their teachers and parents or caregivers.

  • Article: Effects of nutritional status on academic performance of Malaysian primary school children.
    [show abstract] [hide abstract]
    ABSTRACT: Numerous factors are known to affect the academic performance of students. These include prenatal conditions, birth conditions, postnatal events, nutritional, socio-economic factors and environmental factors. This paper examines the nutritional status and its relationship with academic performance of 9-10 years old primary school children recruited randomly in Selangor, Malaysia. A standard self-administered questionnaire was utilized to obtain pertinent information and a face-to-face interview was also conducted with the parents. Results of the academic performances were extracted from the students' report cards. The intellectual performance was assessed using Raven's Coloured Progressive Matrices. Physical examination was also conducted on these students by doctors. Overall 1,405 students and 1,317 parents responded to the survey. Of these 83.6% were Malays, 11.6% Indians, and 4.2% Chinese. The majority of them (82.9%) were from urban areas. The female: male ratio was 51:49; mean age was 9.71 years. The mean height and weight were 32.3 kg and 135.2 cm respectively. Their mean BMI was 17.42 kg/cm2, with 0.9% underweight, 76.3% normal BMI, 16.3% overweight, and 6.3% obese. Academic performance was significantly correlated with breast feeding, income and educational level of their parents, BMI, and whether they have been taking breakfast. There was a weak correlation between presence of anaemia and intellectual performance. Improving the socio-economic status of the parents will lend a helping hand in the academic performance of the students. Since breast feeding is associated with better academic and intellectual performance it must be emphasized, particularly to expectant mothers in the antenatal clinics.

    Article: Impact of sexual health course on Malaysian university students.
    W Y Low
    [show abstract] [hide abstract]
    ABSTRACT: A sexual health course was offered and taught by academic staff from the Faculty of Medicine, University of Malaya during semester II of every year as a university elective course to other university students apart from medical students. The course covered a wide range of topics: adolescent sexuality, family planning and pregnancy, violence against women, alternative sexual behavior, physiology of sex, sex and the disabled, gender bias in sexuality, relationship and marriage, sexual dysfunctions, clarification of sexual attitudes and STDs and AIDS. The Sexual Knowledge and Attitude Test (SKAT-II) was used to measure students' pre- and post-course scores on sexual knowledge and attitudes. Fifty-four students who completed both the pre- and post-course tests showed a significant change in sexual knowledge and their attitudes towards sexual myths and autoeroticism. Sexual knowledge was also positively correlated with age, heterosexual relations, autoeroticism and sexual myths scores. However, sexual knowledge is negatively related to religiosity and the influence of religious beliefs on one's attitudes towards sexual matters. This study showed that the sexual health course offered does have a positive impact in increasing one's knowledge and changing one's attitudes towards sexual issues.

    Article: Reliability and validity of the Spielberger State-Trait Anxiety Inventory (STAI) among urological patients: a Malaysian study.
    [show abstract] [hide abstract]
    ABSTRACT: To validate the English version of the Spielberger State-Trait Anxiety Inventory (STAI) in a sample of Malaysia patients with and without urinary symptoms. Validity and reliability were studied in patients with lower urinary tract symptoms (LUTS) and patients without LUTS. Reliability was evaluated using the test-retest method and internal consistency was assessed using Cronbach's alpha. Sensitivity to change was expressed as the effect size in the pre-intervention versus post-intervention score in additional patients with LUTS who underwent transurethral resection of the prostate (TURP). Internal consistency was excellent. A high degree of internal consistency was observed for each of the 40 items with Cronbach's alpha value = 0.38 to 0.89 while the Cronbach's alpha for the total scores was 0.86. Test-retest correlation coefficients for the 40 items score were highly significant. Intraclass correlation coefficient was high (ICC=0.39 to 0.89). A high degree of sensitivity and specificity to the effects of treatment was observed. A high degree of significant level between baseline and post-treatment scores was observed across nearly half of the items in surgical group but not in the non-LUTS group (control subjects). The STAI is reliable, valid and sensitive to clinical change in a sample of Malaysian patients with and without urinary symptoms.

  • Article: The role of general practitioners in the management of erectile dysfunction-a qualitative study.
    C J Ng, W Y Low, N C Tan, W Y Choo
    [show abstract] [hide abstract]
    ABSTRACT: The objective of this study was to explore the roles and perceptions of general practitioners (GPs) in the management of erectile dysfunction (ED). This qualitative study used focus group discussions and in-depth interviews. This study was conducted based on 28 GPs from an urban area in Malaysia who had managed patients with ED and prescribed anti-ED drugs. Main outcome measures included the roles of GPs in managing patients with ED (active or passive), perceptions regarding ED and the treatment, and factors influencing their decision to prescribe. Majority of the GPs assumed a passive role when managing patients with ED. This was partly due to their perception of the disease being nonserious. Some also perceived ED as mainly psychological in nature. The anti-ED drugs were often viewed as a lifestyle drug with potentially serious side effects. The fear of being perceived by patients as 'pushing' for the drug and being blamed if the patients were to develop serious side effects also hampered the management of this disease. GPs who participated in this study remained passive in identifying and treating patients with ED and this was attributed to their perception of the disease, drug treatment and patient's background.

  • Article: Sexual function outcomes following treatment for lower urinary tract symptoms. A one-year study.
    [show abstract] [hide abstract]
    ABSTRACT: The aim of this study was to assess the effects of treating lower urinary tract symptoms (LUTS) on the quality of sexual function in a one-year follow up. A total of 116 patients with LUTS received alpha-blocker treatment, 111 patients underwent transurethral resection of the prostate (TURP) and 70 patients with renal stones, with no or mild symptoms served as a control group. The patients were assessed at baseline, three months, six months and twelve months using the International Index of Erectile Function (IIEF-15). The surgical group exhibited some changes in the domain of IIEF-15. Patients in the medical group showed improvement in erectile function and intercourse satisfaction, while orgasmic, overall sexual satisfaction and sexual drive were relatively unchanged. In contrast, the surgical group suffered retrograde ejaculation and overall sexual dissatisfaction after undergoing TURP. TURP has been found to be associated with retrograde ejaculation intercourse and overall sexual dissatisfaction.

  • Article: The sensitivity of the Malay version of Brief Manual of Sexual Function Inventory in assessing erectile dysfunction secondary to benign prostatic hyperplasia.
    [show abstract] [hide abstract]
    ABSTRACT: This study aimed to assess the sensitivity of the Malay version of the Brief Manual Sexual Function Inventory (BMSFI) on patients with and without urinary symptoms in Malaysian population. Validity and reliability were studied in patients with lower urinary tract symptoms (LUTS) and patients without LUTS. Reliability and validity was evaluated by using the test-retest method while internal consistency was assessed by Cronbach's alpha. Sensitivity to change was expressed as the effect size in the pre-intervention versus post-intervention score in patients who underwent transurethral resection of the prostate (TURP). Internal consistency was excellent. A high degree of internal consistency was observed for each of the 11 items and 5 domains (Cronbach's alpha value = 0.67 and higher and 0.73 and higher respectively). Test-retest correlation coefficient for the 11 items scores was highly significant. Intraclass correlation coefficient was high (ICC = 0.68 and above). The sensitivity and specificity showed a high degree of sensitivity and specificity to the effects of treatment. A high degree of significant level between baseline and post-treatment scores were observed across 3 domains in the treatment corresponds cohort but not in the control group. The Mal-BMSFI is a suitable, reliable, valid and sensitive to clinical change in the Malaysian population.

  • Article: Malaysian cultural differences in knowledge, attitudes and practices related to erectile dysfunction: focus group discussions.
    [show abstract] [hide abstract]
    ABSTRACT: This qualitative study aimed to examine cultural differences in knowledge, attitudes and practices related to erectile dysfunction (ED) utilizing focus group discussion. Six focus groups consisting of 66 men, 45-70-y-old were conducted-two Malay groups (n=18), two Chinese groups (n=25) and two Indian groups (n=23). Participants were purposely recruited from the general public on a voluntary basis with informed consent. Transcripts were analyzed using qualitative data analysis software ATLASti. The Malay and Chinese traditional remedies for preventing or treating ED are commonly recognized among all races. Many have a negative perception of someone with ED. Malay and Chinese men tended to blame their wife for their problem and thought that the problem might lead to extra-marital affairs, unlike the Indian men who attributed their condition to fate. Malays would prefer traditional medicine for the problem. The Chinese felt they would be more comfortable with a male doctor whilst this is not so with the Malays or Indians. Almost all prefer the doctor to initiate discussion on sexual issues related to their medical condition. There is a need for doctors to consider cultural perspectives in a multicultural society as a lack of understanding of this often contributes to an inadequate consultation.
