Abstract
Response-shift bias has been shown to contaminate
self-reported pretest/posttest evaluations of
various interventions. To eliminate the detrimental
effects of response shifts, retrospective measures
have been employed as substitutes for the traditional
self-reported pretest. Informed pretests,
wherein subjects are provided information about
the construct being measured prior to completing
the pretest self-report, are considered in the present
studies as an alternative method to retrospective
pretests in reducing response-shift effects. In Study
1 subjects were given a 20-minute presentation on
assertiveness, which failed to significantly improve
the accuracy of self-reported assertiveness. Other
procedural influences hypothesized to improve self-report
accuracy-previous experience with the objective
measure of assertiveness and previous completion
of the self-report measure-also were not
related to increased self-report accuracy. In a
second study, information about interviewing skills
was provided at pretest using behaviorally anchored
rating scales to participants in a workshop on interviewing
skills. Response-shift bias was not attenuated
by providing subjects with information
about interviewing prior to the intervention. Change
measures which employed retrospective pretest
measures demonstrated somewhat higher (although
nonsignificant) validity coefficients than measures
of change utilizing informed pretest data.
