Note: Entries above the diagonals are for younger (age less than 40) workers, N = 7,156 to 8,582. Entries below the diagonal are for older (age 40 and older) workers, N = 7,077 to 7,404. Diagonal entries in bold are alpha reliability values for the entire sample with—representing single indicator items. For ∣r∣s ≥ .03, p < .05; for ∣r∣s ≥ .04, p < .01.

^a0 = women, 1 = men.

^b0 = white collar, 1 = blue collar.

^c1 = public sector, 2 = private sector.

^d0 = no supervisory responsibility, 1 = some supervisory responsibility.

^e0 = no stress, 1 = stress.
