In addition, having a biological parent with an alcohol problem was still significantly associated with binge use of alcohol in the past month after controlling for impulsive sensation seeking level (OR = 1.58, 95% CI = 1.29–1.92). The odds ratio for past month binge alcohol use (controlling for ImpSS: 1.58, not controlling: 1.81) was similar to the odds ratio when not controlling for impulsive sensation seeking. Despite the reduction in odds ratio value after controlling for ImpSS score, there was overlap in the 95% confidence intervals between the controlled and non-controlled odds ratio for past month binge alcohol use, suggesting no statistically significant difference.
