Non-substance-related aggression items were taken from the ‘Antisocial’ section of the SSAGA, in which participants reported whether they had ever in their lives perpetrated four different acts of aggression we coded their responses as ‘0 = No’, ‘0 = Yes, with alcohol and/or drugs only’, ‘1 = Yes, clean’, and ‘1 = Yes, with alcohol and/or drugs and clean’. Item content for each phenotype is provided in Table 2. Data collection for COGA was spread across multiple phases with different variants of the SSAGA at each phase. 5,353 of the COGA participants in our sample were assessed multiple times over several years. For these participants, we coded whether each form of aggression occurred at any assessment (1) or none of them (0).
