Chunk #64 — Results — Prediction of Change in Externalizing Problem Status — Change in the pattern of findings due to controlling T1 levels of predictors
In the aforementioned analyses, the T1 and T3 scores for a predictor were both entered in the regressions (recall T1 was a covariate). Often scores on T1 and T3 EC, impulsivity, or emotion were significantly, positively related, and it was possible to have suppression effects with T1 and T3 values of a predictor related in opposite directions to change in maladjustment. Therefore, we examined whether the T1 and T3 predictors (e.g., of impulsivity) of group status were both significant but in different directions. When this occurred, we examined whether the findings in Table 6 or 7 differed if the T1 predictor was not entered in the regression (i.e., whether controlling for the T1 predictor accounted for the significance of the T2 predictor). Relations of T1 and T3 predictors were sometimes significant in the opposite direction, primarily for IMs versus Ds. However, the findings in Table 6 were highly similar when the T1 predictor was not included in the regressions, indicating that the pattern of findings was not due to suppression effects.
