A family adversity score was derived from the following elements: maternal psychopathology, inter-parental cruelty, parental substance misuse and at risk/taken into care (all dichotomous variables) and social deprivation (continuous variable). The total family adversity score ranged from 0 – 15 and was derived from social deprivation (max = 11, Supplementary Table 2) and a maximum score of 1 each from maternal psychopathology, inter-parental cruelty, parent substance misuse and at risk/taken into care (see Table 1).
