Race (1 = White, 0 = Other); Gender (0 = Male, 1 = Female); Work Schedule (0 = Other, 1 = Daytime); WTFC (scale: 1-5); FTWC (scale: 1-5); FSSB (scale: 1-5); Sleep Insufficiency (scale: 1-5); Insomnia (scale: 1-4).

Reliabilities (Cronbach's a) are on the diagonal in parentheses.

All values greater than |.08| are significant at the .05 level.
