Validity and reliability of the SF-36: the Malaysian context.

Results of construct validity and reliability of the SF-36 are described, based on data from a multi-centre study on asthmatics and a population based survey. Questionnaire refinement was carried out between the two studies. Quality of data was good, with all items having less than 0.5% missing values. Floor and/or ceiling effects were observed for REE, REP, PF and SF. For scaling assumptions, correlations between each items and its hypothesized scale were all above 0.50, except for one item in PF. and for both items in SF. Item discriminant validity was an issue for items in VT, SF and MH scales. Cronbach's as for all scales exceeded the recommended 0.70 level, except for SF. Only one latent dimension was identified in principal component analysis, and only 52-53% of variance accounted for. As expected, PF shows high correlations with the physical component while MH was highly correlated with the mental component. Contrasting findings in the loadings of other scales were observed in the asthma data. Age, disease severity and presence of self-reported handicap/disability significantly affect PF, while MH demonstrates no obvious pattern with declining age. In essence, the Malay version of SF-36 could be used in Malaysia, with its generally acceptable internal consistency and validity. The caveat is in the call for additional domains of importance to Malaysians that is not covered by the instrument, and in the caution to be employed when using and construing the instrument.

Quality of life of the Malaysian general population: results from a postal survey using the SF-36.

Population norms for Health Related Quality of Life using SF-36 are described. A national sample was canvassed in 2000 using a self-administered SF-36 in Bahasa Malaysia and English. Response rate was 30.6%, with 3072 usable data. Male: Female ratio was 1.04 and mean age was 39.8 years. Quality of life was affected by age and sex. Older population and women had a poorer quality of life. Population norms for Malaysia differed from those of US, Canada and Australia. The malaysian general population norm described is useful as reference point for studies in Malaysia. Variability in scores by age and sex emphasize the need to use appropriate age- or sex-specific normative data.

Quality of life--how do Malaysian asthmatics fare?

Asthma can place considerable restrictions on the physical, emotional and social aspects of the lives of patients. The assessment of quality of life aims to provide a means of measuring the impact of this disease on patients' lives, from the patients' perspective. A cross sectional multi-centre study was conducted in six government hospitals throughout the country. Self-administered SF-36 was used, and clinical information obtained through interviews and examination. 1612 asthmatics responded. Females constituted 63% of the respondents; mean age was 40.9 years; Malays were the majority ethnic group, while 70.8% had secondary level education and 53.7% were employed. Half had suffered from asthma for at least 13 years, while 46.8% and 23.6% have moderate and severe disease respectively. Quality of life was affected by severity of disease. Asthmatics, had a significantly poorer quality of life than the general US population. Severe asthma disease was associated with a compromised quality of life, similar to that of COPD.

Demotivating factors among government doctors in Negeri Sembilan.

Motivation, especially on the relationship of remuneration of government doctors to it, has long been an issue of concern. This study sought to elucidate the demotivating factors in service and the perceived discrepancy in income. It was conducted amongst doctors serving in the Ministry of Health, Negeri Sembilan, using self-administered questionnaires. Factors considered demotivating were remuneration, workload and recognition given. Career development, promotion prospects, issues with superiors, resources and patient attitudes were other factors identified. On average, respondents expect an income of 1.63 times more than their current drawn salary and 87.2% cited rewards as a recommendation to improve their satisfaction in service. In-service training was desired by almost all. Though the medical profession has traditionally been viewed as altruistic in nature, doctors in service are voicing out their views and perception, and they should be heard.

Job satisfaction of doctors in Negeri Sembilan.

A cross sectional study was carried out in Negeri Sembilan to identify factors associated with job satisfaction of doctors serving in Ministry of Health and their intentions to resign. All Ministry of Health doctors currently working in Negeri Sembilan were included in the study and data collection was done via a self-administered postal questionnaire. The response rate was 69.4%. Out of those who responded, only 31.3% had global job satisfaction, with the majority dissatisfied. Intention to resign was high among 32.7% of the respondents. Factors found to be significantly associated with job satisfaction were age, job designation, income, duration of service and intention to resign. Intention to resign was found to be significantly associated with ethnicity and income. From logistic regression, predictors of job satisfaction identified were age, place of first graduation, and satisfaction with status and autonomy, satisfaction with career development, satisfaction with workload and satisfaction with transfers. Predictors of intention to resign were race, income and global job satisfaction.
