Table 2 Comparing the means of positive and negative subgroup scores on the PAS total scale and its subscales across different independent variables (child age, maternal age, father age) using independent samples t-test, as well as comparing the distribution of positive and negative subgroup scores on PAS total scale and its subscales as regards categorical independent variables (number of sibs, device failure) using chi-square for independence
