¹ Each row presents an individual regression analysis for each outcome with group as a factor while controlling for demographic variables as described in text. Coefficients for group are presented as standardized β for linear regressions and odds ratio (OR) for logistic regressions.

² Bold font = group significant factor in regression analysis at p ≤.001.

³ Rating options ranged from 1 = no more than routine, everyday experience; 5 = similar to experiences that occur on average once every 5 years; 6 = among the 10 most in my life; 7 = among the 5 most of my life; 8 = the single most of my life.
