This longitudinal study examined antecedents and consequences of psychological burnout among human service professionals. Antecedents of psychological burnout included individual and situational characteristics, work stressors, and measures of social support. Consequences of psychological burnout emphasized satisfaction and emotional and physical well-being variables. Participants in the study were 362 school-based educators (teachers and administrators) employed by the same school board. Respondents completed questionnaires sent to them at their schools at two points in time, 1 year apart. Regression analyses of time-lagged data replicated many empirical findings from cross-sectional studies.
