Psychometric Evaluation of the Chinese (Mainland) Version of Job Content Questionnaire: A Study in University Hospitals.

Abstract

To evaluate the psychometric properties of the Chinese (mainland) version of Job Content Questionnaire (JCQ), this validation study was conducted in university hospitals among 193 men and 581 women health care workers. The Cronbach's alpha coefficients for decision latitude, psychological job demands and social support ranged from 0.56 to 0.82, which indicated that psychological job demands had lower internal consistency. The decision latitude displayed a negative correlation with psychological job demands and a positive correlation with social support. Exploratory factor analysis showed 3 meaningful factors that could explain the 3 theoretical dimensions of job strain model. Apart from some uncertainty over psychological job demands particularly, it is concluded that the Chinese (mainland) version of JCQ is a reliable and valid instrument for measuring job stressors, and is applicable to Chinese working population.

Active Job, Healthy Job? Occupational Stress and Depression among Hospital Physicians in Taiwan

“…The JCQ results in our physician sample were much higher than those of many other Taiwanese employees or the national survey means, and similar to the findings of previous cross-occupational studies 17,32) . The mean work demands and job control scores among our physician sample in Taiwan are comparable to the results of surveys of physicians in other countries 15,16) , located in the upper-right quadrant of Fig. 1.…”

“…It has been shown there was a significant difference in the job control degree between genders in our national sample 21) . In another study for a sample of hospital-based Chinese physicians, job control was significantly higher among men, and it was related to their physical health 15) . The result of our study demonstrated that the effect of job control may also be different between genders among physicians relating to their mental health.…”

“…Despite these limitations, the strengths of this study compared to referential international studies 4,15,16) lie in its wide distribution of physician samples include various specialties, plentiful depression risk factors and work condition indicators, and comparisons between JCQ scores with other occupations. Although the results were from survey of volunteer physicians, the major contributions of this pilot study are its reporting of an estimated rate of depression, the status of occupational stress, and the risk and protective factors of depression status among physicians in Taiwan, none of which have been presented before.…”

“…Besides job strain, Karasek's model also postulates that "high work demands, high job control" situations will enhance workers' active learning and lead to a greater internal locus of control. This model has been a centerpiece of current jobstress research, and there has been a growing number of studies that examine depression among employees by deferring to the demands-control-support model 13,14) ; more specifically, there has also been such research into physicians 15,16) . However, until now, little research has been done on the association between occupational stress and depression among physicians.…”
