4.3. Directions for future person-oriented burnout research
As noticed above, although empirical burnout research has been dominated by the variable-oriented approach, there is room for person-oriented studies. Naturally, the approach selected depends on the nature of the research question. If the aim is to study, e.g., whether job characteristics predict burnout over time or whether a particular burnout intervention is beneficial at the average level, a variable-oriented approach, with its analytical methods, is the most appropriate choice. However, when heterogeneity can plausibly be expected in the level or change of burnout, a person-oriented approach is worthwhile. Our suggestions for future research avenues, based on the three categories of person-oriented research, i.e., burnout and well-being types and trajectories, are presented next. We conclude this section by deliberating what a holistic-interactionistic theoretical view of burnout could be. First of all, more longitudinal studies covering longer followups are needed. As the majority of the burnout-type studies were cross-sectional, they offered only a sketch of burnout symptoms on the individual level. The different types found were typically interpreted according to the developmental process of burnout (Golembiewski et al., 1986; Leiter & Maslach, 1988). However, in order to properly investigate the development process of burnout via types, longitudinal studies with several measurements are needed. In addition, research on the long-term development of burnout has focused mainly on the early career stage, which is a period characterized by instability in levels of job-related wellbeing (Mäkikangas et al., in press). Therefore developmental paths of burnout need to be investigated throughout the career, using longer follow-ups, in order to gain a more complete picture of typical burnout trajectories.
