Mean (±SD) scores for stress, energy, large sleep problems, difficulties falling asleep, and psychobiological problems among affective profiles.

	Self-fulfilling	High affective	Low affective	Self-destructive
	(high PA and low NA)	(high PA and high NA)	(low PA and low NA)	(low PA and high NA)
Energy	30.49 ± .86*	26.02 ± .89	23.90 ± .88	21.70 ± .73
Stress	15.94 ± .99	20.16 ± 1.13▲	16.04 ± .86	26.50 ± 1.15▲
Major sleep problems	15.50 ± 4.20	19.30 ± 4.19▲	17.30 ± 4.69▲	19.95 ± 4.86▲
Difficulties falling asleep	17.42 ± 4.29	21.34 ± 4.96▲	18.52 ± 4.88	23.52 ± 6.49▲
Psychophysiological problems	20.61 ± .93	25.63 ± 1.07▲	24.06 ± 1.09▲	29.24 ± 1.09▲

N = 304, ^∗higher than the other three groups, ^▲higher than self-fulfilling.
