For the elder adult group, no comparisons between bisexual and gay/lesbian participants were tested, due to lack of adequate statistical power. For emerging adults: R2 = 0.11, R2 adjusted = 0.11, F8,3512 = 52.21, p < .001. For young adults: R2 = 0.15, R2 adjusted = 0.15, F8,4827 = 104.42, p < .001.For early middle adults:R2 = 0.16, R2 adjusted = 0.16, F8,6420 = 157.79, p < .001. For late middle adults R2 = 0.19, R2 adjusted = 0.19, F8,6549 = 188.06, p < .001. For elder adults: R2 = 0.19, R2 adjusted = 0.19, F6,3401 = 135.33, p < .001.
