Sequential Tree Analysis of Work Stressors: Exploring Score Profiles in the Context of the Stressor-Stress Relationship

In recent years concerns about whether the different measures of work stressors provide adequate information on the stressors themselves have led a number of reviewers to suggest that old constructs should be reconsidered and alternative approaches to measurement considered. One such alternative approach would be to consider the relationship between different work stressors in terms of score profiles and whether different score profiles emerge at different levels of tension. Sequential tree analysis was used to segment or split a sample into homogeneous subgroups reflecting the stressor or combination of stressors that reflected different levels of tension. The visual display that emerged from this analysis suggests that: (1) when considering the relationship between stressors and tension it is important to recognize that while absolute levels of work stressors scores may be low this is no reason to assume that the stressor-tension relationship will be correspondingly low; and (2) although individuals may report the same overall score for a work stressor, their experience of that stressor may be quite different. Finally, these results point to the need to consider the impact that generalizing work stressor scores may have on intervention strategies.
