The purpose of this study was to evaluate the effects of pre-test sensitization on psychological outcomes following 30-mins of cycling exercise (CE), hypnosis (HY), and quiet rest (QR). A Solomon 6-group design was used and participants were randomly assigned to experimental and control conditions (CE, HY, & QR). The STAI and the POMS were administered to half of the participants (N = 54) before the intervention while the other half (N = 54) did not receive a pre-test. This design allows for the comparison of post-test measurements on participants who have been pre-tested and those who have not. The data were analyzed with a series of repeated measures ANOVA's using the post-test variables as dependent measures. Results indicated that significant state anxiety and mood improvements were measured following each condition (CE, HY, & QR) in those groups that received a pre test. These improvements were not significantly different for the cycling, hypnosis, or quiet rest groups. Additionally pre-test measurement did not appear to effect postûtest outcomes. It is concluded that the common practice of pre-testing of affective variables prior to exercise, hypnosis, or quiet rest does not influence post-test outcomes.
