A noteworthy characteristic of the present findings is that the moderator models for self - reported vision controlled for the direct
effects of visual acuity and vice versa.
Supportive spouse behaviors also moderated
the effects of visual acuity on functional limitations and depressive symptoms (B = 0.88, β =.07, t = 2.01, p <.05 and B = 1.79, β =.09, t = 2.57, p <.01, respectively, for the interaction terms).

Two separate moderated regression models were tested for each indicator
of quality
of life using the SPSS 17.0 statistical software package; one model tested the moderating role
of marital quality in the
effects of self - reported (subjective) vision controlling for
visual acuity (objective vision) and the second tested the same in the
effects of objective vision controlling for subjective vision.
This approach is more rigorous because it examines the simultaneous
effects of both perceived
visual function and objective
visual acuity.

of marital quality for the
effects of self - reported vision and
visual acuity.

of marital quality in the
effects of self - reported vision and
visual acuity.
Future research may gain further by assessing even more specific aspects
of visual function objectively (e.g., impairment in depth perception, extreme contrast or brightness sensitivity in addition to
visual acuity as assessed in NSHAP) and subjectively (e.g., self - reported trouble with reading newspaper print and recognizing people at a small distance in addition to the global assessment
of one's vision as assessed in NSHAP) in the study
of the
effects of vision on quality
of life and the capacity
of a good marriage to alter these
effects.
The results showed that higher marital satisfaction was a strong buffer
of the
effects of poorer self - reported vision on functional limitations and depressive symptomatology and a weaker but significant moderator
of the
effects of lower
visual acuity on functional limitations.
