decline
Weaker negative mood regulation expectancies (lower belief in ability to alter negative moods) were associated with greater poly-substance use over time, specifically associated with more marijuana and alcohol use but not cigarette use, with a gender interaction for marijuana use showing opposite directions for males versus females.
| Effect size | beta = -.04, t(7726) = -3.34 |
| Comparator | Stronger mood regulation expectancies within cohort (continuous predictor in multi-level model) |
| Effect summary | decline; beta = -.04, t(7726) = -3.34 |
