Region Boundaries for the Effect of Internalizing Problems on Peer Delinquency at Different Levels of Externalizing Symptoms for the Alcohol Model
Note. Extern = externalizing symptoms, W = Wave and SD = Standard Deviation. The scales of both internalizing and externalizing symptoms are standardized (mean = 0, SD = 1). The .06 SD and −1.3 SD Extern slopes were significantly different than 0. Slopes between internalizing problems and peer delinquency become steeper, remain negative, and remain significantly different than 0 as externalizing problems increase from .06 SD. Likewise, slopes between internalizing problems and peer delinquency become steeper, remain positive, and remain significantly different than 0 as externalizing problems decrease from −1.3 SD. A very similar pattern was observed in the Other SU model for the main analysis and for the anxiety x externalizing problems model in which depression and anxiety were separated.
