report are closely related because they reflect consistent levels of drinking across time. In addition, at least 6 outcomes are predicted by current drinking but not by either antenatal or retrospective report, suggesting that current drinking is also assessing something quite separate from effects of prenatal alcohol exposure. Taken together, these results indicate that statistically controlling for current drinking would over-correct for its potential influence on retrospective report and that retrospective report is a valid measure of prenatal maternal alcohol consumption.
