Instrumental support
Associations between instrumental support and overall HRQoL
were reported in two studies. Inconsistent results were found: one
study found a non-significant association between more instrumental
support and worse HRQoL [15], whereas the other study
found a significant association between more instrumental
support and better HRQoL (>0.30) [17]. One study reported also
a mediating effect of instrumental support between the psychosocial
and physical subscale of HRQoL
