a household where the coresident parents were married or in a marriage-like relationship at the initial assessment (see also Fosco & Feinberg, 2014). The final analysis sample consisted of 452 families. Comparisons between our analytic sample and the larger population of PROSPER two-parent families (N = 8,485) revealed few differences. There were slightly fewer two-biological-parent families (76.9% vs. 80.2%), fewer adolescents on free/reduced-price lunches (20.9% vs. 28.1%), and more Caucasian participants (91.1% vs. 86.0%) in our analysis sample. Effect sizes for these differences were all small (r < .05). Parent warmth/support, hostility, involvement, and family cohesion did not differ between the samples.
