Activity Caucasians (N = 183) Mean (SD) African Americans (N = 190) Mean (SD) Univariate Significance
Social life 2.23 (1.62) 2.77 (1.73) P < 0.05
Sexuality 1.84 (1.86) 2.64 (1.95) P < 0.001
Sleep 3.11 (1.65) 3.54 (1.56) ns
Recreation 2.54 (1.66) 3.03 (1.77) P < 0.05
Household chores 2.71 (1.64) 3.27 (1.73) P < 0.01
Working at a paid job 2.16 (2.07) 3.45 (1.92) P < 0.001
Self-care 0.84 (1.40) 1.53 (1.73) P < 0.001
Parenting 1.14 (1.65) 1.89 (1.97) P < 0.001
Routine physical activities (e.g., climbing stairs) 2.57 (1.79) 3.05 (1.78) P < 0.05
Exercise 2.87 (1.71) 3.33 (1.69) P < 0.05

Possible range was 0–5 (low to high interference) for ratings of all activities. The group sample sizes were reduced because of missing data and deletion of six outliers.
