Summary

This summary is machine-generated.

The shortened Swedish Demand-Control-Support Questionnaire (DCSQ) effectively measures work psychosocial factors in HUNT4. This validated tool assesses demand, control, and support, proving reliable across occupational groups.

Area Of Science

  • Occupational Health Psychology
  • Psychometrics
  • Sociology of Work

Background

  • The Swedish Demand-Control-Support Questionnaire (DCSQ) is a key instrument for assessing the psychosocial work environment.
  • A nine-item subset of the original DCSQ was utilized in the Trøndelag Health Study (HUNT4) between 2017-2019.
  • This subset included three items each from the dimensions of demand, control, and support.

Purpose Of The Study

  • To evaluate the internal reliability of the nine DCSQ items employed in the HUNT4.
  • To ascertain the dimensional structure of these nine DCSQ items within the HUNT4 cohort.
  • To validate a shortened version of the DCSQ for use in large-scale health studies.

Main Methods

  • Confirmatory factor analysis (CFA) was conducted on a sample of 21,187 HUNT4 participants with known occupations.
  • Internal reliability was assessed using composite reliability and item-total correlation.
  • The dimensional structure was examined for the overall sample and subsequently across different occupational groups.

Main Results

  • After removing the item "Work creativity," the remaining eight DCSQ items demonstrated a robust three-factorial structure, consistent with the original DCSQ.
  • Good internal consistency was observed for all three dimensions, with composite reliability ranging from 0.709 to 0.851.
  • The established dimensional structure remained consistent across various occupational groups.

Conclusions

  • The condensed nine-item DCSQ, as implemented in HUNT4, is a reliable and valid instrument for measuring key aspects of the psychosocial work environment.
  • The findings support the use of this shortened DCSQ for assessing work-related demand, control, and social support.
  • The validated structure across occupational groups enhances its utility in diverse research settings.

Self-Report Tests of Personality 01:22

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Factorial Design 02:01

Factorial Analysis is an experimental design that applies Analysis of Variance (ANOVA) statistical procedures to examine a change in a dependent variable due to more than one independent variable, also known as factors. Changes in worker productivity can be reasoned, for example, to be influenced by salary and other conditions, such as skill level. One way to test this hypothesis is by categorizing salary into three levels (low, moderate, and high) and skills sets into two levels (entry level...

Response Surface Methodology 01:16

Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.
The process of RSM involves several key steps:

Conducting Experiments:
The first step is to conduct experiments by systematically varying the input variables. This is typically done using a specific experimental design, such as a factorial...

Self-Discrepancy Theory 02:45

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.  

According to the self-discrepancy theory, people hold beliefs about what they’re really like—their actual self—as well as what they would ideally like to be—their ideal...
