Distinctions between patterns of inconsistent reporting (i.e., older vs. younger age at subsequent reports) are rarely made in the literature, but our results indicate that the two patterns differ with respect to relevant childhood and adolescent risk factors. Compared with consistent reporters, elevated rates of CSA and cannabis abuse were observed in individuals reporting a younger age at Time 2, but not in those reporting an older age at Time 2. Conversely, older age at second report was associated with increased likelihood of endorsing CPAN and decreased likelihood of endorsing major depressive disorder and regular smoking, but the prevalences of these conditions in those reporting a younger age at Time 2 were comparable to those of consistent reporters. Given the lack of literature in this area, we can only speculate on why these two types of inconsistent reporting are differentially associated with the risk factors we examined. One possible explanation for the decreased rates of major depressive disorder and regular smoking in Group 3 is that both conditions are associated with problem drinking, which we know to be lower in
