a

All values are β indices with the exception of R2 and F values. Indices are significant at P < .05 when not otherwise specified.

b

Positive β values mean that the latter category (hypertension or women) is associated with higher scores on the SF-36 or SWLS; negative scores mean that the first category (CHF or men) is associated with higher scores on the SF-36 or SWLS.

c

Depressive factor = (0.833 HDRS16) + (0.833 MADRS9).

d

Suicidality factor = (0.907 HDRS item 3) + (0.907 MADRS item for suicidal ideation).

e

P values associated with each step of the regression analysis.

*

Not significant.
