Hierarchical regression analysis
As shown in Table 8 and Table 9, age and monthly income (RMB) were added
in the first step. In the second block, depression, anxiety and
perceived social support (PSS) were added respectively. Finally, the
PSS&Depression interaction term and the PSS&Anxiety interaction term
were added in the last block respectively. The PSS&Depression
interaction term was negatively correlated with quality of life
(β=-0.241, p <0.01), and explained an extra 5.7% of the
variance (F=68.649, adjusted R2=0.369,
ΔR2=0.050, p <0.01). The PSS&Anxiety
interaction term was negatively correlated with quality of life
(β=-0.235, p <0.01), and explained an extra 5.6% of the
variance (F=65.813, adjusted R2=0.359,
ΔR2=0.048, p <0.01).
