or older, and had genomic data available for at least one biological parent. These individuals came from 840 extended families and 1,893 nuclear families. Offspring participants’ age at the last interview ranged between 18–79 (M = 30.07, SD = 9.22; 51% female). Of these participants, there were 3,029 individuals whose biological father completed at least one SSAGA interview and 2,908 individuals whose biological father had genomic data available for analysis (fathers’ age at last interview ranged between 21–91, M ± SD = 52.96 ± 12.96 years); there were 3,728 individuals whose biological mother completed at least one SSAGA interview and 3,635 individuals whose biological mother had genomic data available for analysis (mother age at last interview ranged between 18 and 88, M ± SD = 50.79 ±13.28 years). The secondary sample was a subset of the primary analytic sample, limited to offspring participants for whom data on the parental bonding measure were available (n = 642; see more details below).
