Relationships between social support and coping were examined over a o
ne-year period in a sample (n = 120) exposed to a specific stressor (i
.e. a spinal cord injury). Two issues were evaluated: (1) patterns of
social support and coping over time; and (2) the direction of the effe
cts of coping on social support or vice versa. Subjects had incurred a
spinal cord injury within the preceding year, completed their rehabil
itation, and returned to the community. They were assessed at 1, 4 and
12 months post-discharge to capture possible changes in patterns of s
ocial support and coping. Covariance Structure modelling indicated a s
ingle-factor construct based on three measured subscales for social su
pport (instrumental/informational/emotional), and for coping em-orient
ed/perception-oriented/emotion-oriented). While the factor structure o
f coping was invariant over time, the structure of social support chan
ged from a high concentration of informational support at one month to
a higher saturation of emotional support at 4 and 12 months, potentia
lly reflecting changes in the salience of different components of the
network. The perceived availability of social support was seen to have
direct effects on future coping. At one month, social support had a d
irect positive effect on coping at four months. However, at four month
s social support had a negative effect on coping at 12 months, which m
ay reflect a change in the structure of the social support construct i
tself. That is, as the factor structure of social support varied with
time, coping may also have been influenced by differing perception of
one's needs and circumstances. Thus, the study provides evidence for t
he dynamic effects of social support on coping, depending on one's sta
ge in the process of long-term adjustment. The findings underscore the
interplay between social support and coping, and the need for future
research and practical applications to recognize temporal effects on t
he relationships between these two complex constructs.
