## Cross Temporal Meta-Analysis Ignores the Nesting of Studies within Time

Visontay et al. (2020) CTMA Recently, a study by Visontay, Mewton, Sunderland, and Slade (2020) published in Drug and Alcohol Dependence used cross-temporal meta-analysis (CTMA) to estimate changes in young adults’ harmful alcohol consumption between 1989 and 2015. Although compelling, the results of this study rest upon the application of CTMA, which has been long criticized for its reliance on a variety of tenuous assumptions (see Donnellan, Trzesniewski, & Robins, 2009; Trzesniewski, Donnellan, & Robins, 2008).
