Evidence cited in Hard Edges from the MEH survey (which included one Scottish city, Glasgow) showed very high levels of retrospective reporting of a range of traumatic or disruptive experiences in childhood by people experiencing two or more of the original SMD domains, with only 15% of the SMD3 group reporting no such issues (Bramley et al, 2015). Quantitative analysis of the GUS survey shows that, where there are parental SMD issues, such as substance dependency and mental ill-health, children are more likely to have additional support needs flagged or concerns about child development voiced. In these cases home life is more likely to be characterised by chaos vs order and by higher levels of conflict and adverse impacts on child development, which are accentuated as the child gets older (see Technical Report, sections 11.3 & 11.4).
