In total, 98 articles encompassing 103 studies met inclusion criteria (five of the 98 articles reported results for two independent samples). A list of included and excluded studies and how they were coded is provided in the data supplement that accompanies the online edition of this article. Analyses were limited to interactions discussed in the abstracts of articles because results not mentioned in the abstract were usually described in insufficient detail for accurate categorization. Each of the 103 studies was classified either as novel (containing no previously reported interactions) or as a replication attempt of a previously reported interaction. Replication attempts were defined as reports of an earlier cG×E finding in a separate article in which 1) the phenotypic variable was identified with the same name as the variable in the original report, even if specific scales differed (e.g., depression could be measured via self-report or clinician diagnosis); 2) the genetic polymorphism and genetic model (e.g., additive) were the same as in the original study; 3) the environmental moderator was substantively the same; and 4) replication results were reported for
