Factor structure and longitudinal measurement invariance of the demand control support model: an evidence from the Swedish Longitudinal Occupational Survey of Health (SLOSH).

ABSTRACT:

Objectives

To examine the factor structure and to evaluate the longitudinal measurement invariance of the demand-control-support questionnaire (DCSQ), using the Swedish Longitudinal Occupational Survey of Health (SLOSH).

Methods

A confirmatory factor analysis (CFA) and multi-group confirmatory factor analysis (MGCFA) models within the framework of structural equation modeling (SEM) have been used to examine the factor structure and invariance across time.

Results

Four factors: psychological demand, skill discretion, decision authority and social support, were confirmed by CFA at baseline, with the best fit obtained by removing the item repetitive work of skill discretion. A measurement error correlation (0.42) between work fast and work intensively for psychological demands was also detected. Acceptable composite reliability measures were obtained except for skill discretion (0.68). The invariance of the same factor structure was established, but caution in comparing mean levels of factors over time is warranted as lack of intercept invariance was evident. However, partial intercept invariance was established for work intensively.

Conclusion

Our findings indicate that skill discretion and decision authority represent two distinct constructs in the retained model. However removing the item repetitive work along with either work fast or work intensively would improve model fit. Care should also be taken while making comparisons in the constructs across time. Further research should investigate invariance across occupations or socio-economic classes.

Project description:Self-control is an important trait for humans to perceive inner and outer perceptions while maintaining harmony with others in society. People with lower self-control are more likely to engage in undesired or irresponsible behavior. The Brief Self-Control Scale (BSCS) is an effective scale with a brief set of items which can effectively measure the level of an individual's control abilities. So far, it has been widely used in many longitudinal studies. However, the factor structure of the scale remains controversial, and far fewer studies have examined the longitudinal measurement invariance of the BSCS. This study aimed to revise the BSCS and test its factor structure for use in Chinese adolescents. Three samples of adolescents (N = 1,330/1,000/600, 11-19 years of age) were used. The item-total correlation and inter-item correlation coefficients were used to evaluate the quality of items. The exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and the principle component analysis (PCA) of the residuals were performed to test the factor structure of the BSCS. Three nested models were used to test the longitudinal measurement invariance (LMI) of the BSCS. Pearson correlation coefficient and Cronbach's alpha coefficient were conducted to test the criterion validity and internal consistency reliability, respectively. According to the CFA of different dimensional models of the BSCS, the results did not support the two-dimensional model, and poor factor loading was found for Item 12. Based on this, combined with lower item-total correlation and item-item correlations, Item 12 was eliminated. Based on results of the EFA with both Kaiser eigenvalues and minimum average partial correlations, only one factor of the revised 12-item BSCS was extracted to make the fit indices of the confirmatory factor analysis acceptable. Meanwhile, the results of principle component analysis of the residuals supported the unidimensional assumption. The fit indices of three nested models supported the longitudinal measurement invariance, indicating that this scale has the same meaning over time. The internal consistency coefficient of the BSCS-12 was 0.81 and the test-retest reliability was 0.70. Good concurrent validity was also demonstrated. Overall, these findings suggest that the revised 12-item Tangney's Brief Self-Control Scale has a one-dimensional structure and has good reliability and validity in Chinese adolescents.

Project description:BackgroundDigital consultation with primary care physicians via mobile telephone apps has been spreading rapidly in Sweden since 2014. Digital consultation allows remote working because physicians can work from home, outside their traditional primary care environment. Despite the spread of digital consultation in primary care, there is a lack of knowledge concerning how the new service affects physicians' psychosocial work environment. Previous research has focused primarily on the patients' point of view and the cost-effectiveness of digital consultation. Hence, there is a paucity of studies from the perspective of physicians, focusing on their psychosocial work environment. The aim of this study was to investigate primary care physicians' perceived work demands, control over working processes, and social support when providing digital consultation to primary care patients.MethodsThe study has a qualitative design, using semi-structured interviews conducted in Sweden in 2019. We used a purposeful sampling strategy to achieve a heterogeneous sample of physicians who represented a broad spectrum of experiences and perceptions. The interviews were conducted by video meeting, telephone, or a personal meeting, depending on what suited the participant best. The interview questions were informed by the Job Demand-Control-Support (JDCS) model, which was also used as the framework to analyze the data by categorizing the physicians' perceptions and experiences into the three categories of the model (Demand, Control, Support), in the deductive analysis of the data.ResultsAnalysis of the data yielded 9 subcategories, which were mapped onto the 3 categories of the JDCS model. Overall, the participants saw numerous benefits with digital consultations, not only with regard to their own job situation but also for patients and the health care system in general even though they identified some shortcomings and risks with digital care.ConclusionsThis study has demonstrated that physicians perceive working with digital consultation as flexible with a high grade of autonomy and reasonable to low demands. According to the participants, digital consultation is not something you can work with full time if medical skills and abilities are to be maintained and developed.
