Hi, I am doing a parallel process LGM and calculate a conditional effects model to better understand the effect of my IV on the slope of the DV. I used the formula outlined by Curran, Bauer, and WIlloughby using the mean +/- one standard deviation of the initial intercept mean (provides me with low, mean, and high levels of the intercept). The trend of the DV is negative over time; however, none of the conditional effect lines in the graph I create are going down? How can this be when the overall sample trend is negative? |

In the regression of s on i, what are the intercept and regression slope? What are the mean and variance of i? |

intercept is depression score and slope is substance use change. The mean of depression I is 8.53, variance 17.6 and the slope of substance is -0.214, variance 1.7. |
