SD = standard deviation. Only ages at which there were at least 100 participants assessed are included in this table.
These sample sizes refer to participants who provided data on both depressive symptoms and alcohol use-related problems.
Means and standard deviations for alcohol use-related problems were derived from raw data; correlations with depressive symptoms were calculated using log-transformed alcohol problem variables. Mean numbers of depressive symptoms differed (p<.05) between males and females at all ages except age 26. Mean numbers of alcohol problems differed (p<.05) between males and females at all ages except 12, 16, and 26. Correlations between depressive symptoms and alcohol problems differed (p<.05) between males and females at ages 12, 13, 14, 15, 16, 19, and 22 (but not at other ages).
