“…Adults were stratified into the following age groups: young adulthood (Group 1: ages 18-39; M age = 30.72, SD = 6.05, N = 854, middle adulthood (Group 2: ages 40-64; M age = 50.6, SD = 6.5, N = 1,848) and older adulthood (Group 3: ages 65-75; M age = 70.6, SD = 5.05, N = 250). We selected these age groupings based on a priori, developmental life stage considerations that have been underscored as important in recent research (Mehta et al, 2020); although there is no 'validated' age cutoff, the age groupings chosen in our study are generally accepted within the developmental literature as they coincide with social and psychological resource changes as well as biological changes in adult development (Robert & Feldman, 2019). Specifically, young adulthood (ages 18-39) is generally characterized by transitioning to a committed romantic partnership (and typically marriage), new parenthood, building a career while balancing multiple professional and family roles, and overall good physical health (Mehta et al, 2020;Robert & Feldman, 2019).…”
