Associations remained statistically significant when participants’ alcohol and cannabis use were included in the model (intercept, p < .01; slope, p < .001; Table 3). However, when parental AUD was included in the model, only a decreased rate of change in no-go frontal theta oscillation from baseline to follow-up 4 was observed (intercept, p > .05; slope, p < .05; Table 3). When cognitive impulsivity (BIS subscale, baseline assessment) was included in the model, associations were no longer statistically significant (intercept, p > .05; slope, p > .05). When additional pathways from the slope and intercept factors to INT pathology, EXT pathology, AUD symptoms, and CUD symptoms (≥18 years old) were included in the model, the rate of change in no-go frontal theta oscillation was positively associated with INT pathology and AUD symptoms at participants’ most recent follow-ups (p < .001; Figure 2). In addition, models including intercepts as covariates were examined and results remained largely unchanged (results available upon request).
