Discriminant Validity of the Stress-Energy Questionnaire Regarding Work and Leisure Time
(), Elisabeth Svensson
() and Gunnar Ahlborg Jr
Abstract: Purpose: The Stress-Energy Questionnaire (SEQ) is an
instrument developed to measure two aspects of mood at work. This study
evaluates the discriminant validity of the SEQ when assessments are
separated into work and leisure time. Furthermore, the use of the scale
categories was explored with respect to gender.
Methods: The data
(n=2817, 84% women) came from a survey involving public health care
employees and insurance office workers in western Sweden. As the data
consist of ordered categories, a nonparametric statistical method for
paired ordered categorical data was used.
Results: A significant
systematic disagreement meaning higher stress and energy levels at work
compared to leisure time was found for all items in both women and men.
According to our study, one can expect a higher level of stress and energy
at work as compared to leisure time, but the high individual variations
indicated heterogeneous data. Differences were also found between how men
and women used the scale categories; for example, the endpoint categories
not at all and very much were more often used by women, while men use the
central categories hardly, somewhat, and fairly more frequently than women.
Conclusion: This study showed that the two sets of items referring to
work and leisure time, respectively, discriminate the responses.
Distinction between work and leisure time is recommended when using this
modified version of the SEQ. To use only work assessment would mean a loss
