Simple Slopes for the Interaction of Vested Interest and Attitudes on the Outcome of Intentions

Study 1a: Nonmedical
Prescription Stimulants
(N = 310)		 Study 1b:
Marijuana
(N = 93)
B SE t(299) B SE t(83)
Vested
interest
perceptions		 Low (−1SD) .30** .11 2.74 .01 .03 .24
Moderate (0) .64*** .08 8.07 .06** .02 2.75
High (+1SD) .98*** .09 11.32 .12*** .03 4.25

Note. Values represent conditional effects of the predictor variable (attitudes) at different values of the moderator (vested interest). Predictor variables were z-scored to produce standardized (B) estimates. A log transformation was performed on intentions to use marijuana to reduce levels of skew and kurtosis (Study 1b).
