The focus of the present study is to examine the relationship between
Antonovsky's Sense of Coherence (SOC), the nature of patient pathology
, situational coping responses, and role overload in Belgian primary c
aregivers to dementing and nondementing chronically ill family members
(n = 126). The hypotheses that caregivers with a strong SOC are likel
y to cope in situationally-appropriate ways were confirmed. Sense of C
oherence appears to have a protective effect, in the sense of the bein
g related to management of the meaning of the situation, the selection
of realistic coping strategies, and the avoidance of potentially mala
daptive or unhealthy behaviors. Multi-variate analyses revealed that S
OC alone predicted 29% of the variance in role overload for caregivers
to dementing patients, while strategies to manage the situation and s
ymptoms of distress were the only significant, yet maladaptive, coping
responses for caregivers to nondementing patients. It is arguable tha
t these findings indicate a threshold effect of the nature of patient
disability on the protective effects of the sense of coherence. The mu
lti-dimensional impact of caring for a patient with a dementing disord
er exerts a unique and particular strain, one that requires caregivers
to be able to cope by redefining the meaning of their relationship wi
th their dependent. The theoretical rationale for the hypothesized thr
eshold effect is explored.
