This article begins with a brief review of the current literature on t
he structure and measurement of perfectionism. It is concluded from th
is review that two major types can be distinguished, a normal/healthy
form and a pathological form. These two forms are then defined as posi
tive and negative perfectionism and related directly to Skinnerian con
cepts of positive and negative reinforcement. The positive/negative di
stinction is then further elaborated on in terms of approach/avoidance
behavior, goal differences, self-concept involvement, emotional corre
lates, and the promoting environment. Finally, some of the more obviou
s theoretical and practical implications are briefly explored.
