Slope 1: high PsyCap and family support; slope 2: high PsyCap and low family support; slope 3: low PsyCap and high family support; slope 4: low PsyCap and family support. LLCI, lower level of the 95% confidence interval; ULCI, upper level of the 95% confidence interval. *p < 0.05, **p < 0.01, ***p < 0.001.
