	PTSD Diagnosis subscale (n = 101*)

Single ventricle	1.09 (1.10)	0.01, 1.73	0.024
Number of children	3.11 (1.66)	1.09, 8.88	0.033

Note. SE=Standard Error; CI =Confidence Intervals; PSI= Parenting Stress Index (Abidin, 1995); PTDS=Post-traumatic Stress Disorder Scale (Foa et al., 1997);

Sample sizes vary in the multivariable models, by the covariates’ missingness rates.
