the most frequently used scale to assess teacher stress and
burnout is the Maslach Burnout Inventory (MBI; Maslach &
Jackson, 1981). Often overlooked by users of the MBI, however,
is the fact that the MBI measures burnout, not stress. Though
the two constructs are related, both conceptually and
correlationally, they are nonetheless separate entities. Indeed,
the burnout construct and its factors -- emotional exhaustion,
depersonalization, and a lack of personal accomplishment -- are
thought to be the end result of long-term stressful situations (Maslach,
1981). Thus, one cannot become "burned out" without
experiencing intense stress for an extended period of time.
Human nature being what it is, however, one does not usually
"bum out" on the job if stress is experienced at
moderate levels. Thus, the TSI assesses stress in terms of very
different, and much more teacher-specific, factors than those
that define the MBI.
