Two experiments were conducted to examine if context effects occur whe
n subjects respond to the Self-Monitoring Scale (Snyder, 1974). A situ
ated identities hypothesis was offered to explain why context effects
occur. In Experiment 1, the type of relevant identity expected to be c
onveyed was manipulated. Subjects completed the scale under standard t
esting conditions or with instructions that the scale measured acting
ability. Males scored higher than females on the Self-Monitoring Scale
in the standard testing condition. However, when told that the scale
was a measure of acting ability, the average score of females was high
er than in the standard condition, whereas the average score for males
was lower than the standard testing condition. In Experiment 2, subje
cts responded to the scale after responding to questions about sexual
deception. As compared to a standard condition, scores were significan
tly lower, also suggesting the existence of context effects. Suggestio
ns are offered for avoiding context effects in the use of the Self-Mon
itoring Scale. (C) 1995 Academic Press, Inc.
