ABSTRACT
Background: The General Practice Physical ActivityQuestionnaire (GPPAQ) is a validated and reliable screeningtool to measure the level of physical activity in adults.However, it has never been translated and validated inMalaysian population. This study aimed to translate theGPPAQ into Malay language and to evaluate thepsychometric properties of the Malay-translated GPPAQamong shipyard workers.Methods: The original English version of GPPAQ wastranslated forward and backward into Malay version byexperts. The final version of the Malay-translated GPPAQwas then tested for validity and reliability. A cross-sectionalstudy design was performed and systematic randomsampling was used to select respondents. Construct validityand internal consistency of the Malay-translated versionwere tested using exploratory factor analysis andCronbach’s alpha respectively.Results: Sixty-two male shipyard workers participated inthis study. The GPPAQ showed good factor loading valuesfor all items (0.608-0.834). The exploratory principalcomponent factor analysis delineates all seven items intotwo factors with variance of 41.65%. The Cronbach’s alphavalue was good with 0.81, 0.84 and 0.76 for total scale, factor1 and factor 2 respectively.Conclusion: The Malay-translated version of GPPAQ hashigh psychometric properties. Therefore, it is a validinstrument to assess physical activity among Malaysianworking population, particularly in male shipyard workers.
ABSTRACT
The prevalence of occupational stress among academician is increasing in developed and developing countries. The job is not only to teach, but also involve in doing research, publications, consultation and administrative work. This study aims to assess the prevalence of occupational stress among academic staff in a research university and to investigate the association and correlation between stress and job factors which are career development, research, teaching and interpersonal relationship. One research university in Malaysia was selected randomly. A cross-sectional study was conducted and the respondents were recruited by using a randomized stratified sampling method. A total of 380 self-administered and validated Depression, Anxiety and Stress Scale-21 (DASS-21) and Stress Sources Questionnaires (SSQ) were distributed among academic staff between March to May 2012. The statistical analyses used were χ2, independent–t test and Pearson Correlation. Response rate was 81.1%. Stress prevalence was 22.1%. All socio-demographic factors showed no association with stress except ethnic group. Teaching, research and career development had significant association with stress among academic staff (p<0.05). Overall result showed career development, that include university condition and required publications for promotion were the greatest source of stress among the academicians. Occupational stress showed positive linear relationship to career development, research and teaching. There was a fair positive relationship between occupational stress and career development, research and teaching. It is recommended to organize continuous stress assessment program to identify and evaluate the current level of stress at the university level. This data could be a foundation for implementing prevention and control measures to reduce stress in the workplace.
