Alcohol consumption's effects on working memory: Examining familial confounding.

ABSTRACT:

Objective

The purpose of our study was to provide a more rigorous test of the causal hypothesis that chronic alcohol use impairs working memory performance.

Method

We measured linear associations between a latent factor representing alcohol consumption and accuracy across four working memory tasks before and after accounting for familial confounding using a cotwin control design. Specifically, this study examined accuracy through a latent working memory score, the National Institutes of Health (NIH) Toolbox List Sorting, NIH Toolbox Picture Sequence, Penn Word Memory, and 2-back tasks. The study included data from 158 dizygotic and 278 monozygotic twins (M_age = 29 ± 3 years).

Results

In our initial sample-wide analysis, we did not detect any statisti
