18. Child refers to a blood, step- or adopted son or daughter (regardless of age or marital status) who has usual residence in the household of at least one of the parents, and who has no partner or own child(ren) in the same household.

Such an act of abuse becomes an act of domestic violence if it is committed within the environment of the home or even outside, by a `relevant person' defined as a father/mother, grand parent, step father/mother, aunt, uncle, son/ daughter, grandson/daughter, step son/daughter, niece/nephew, brother/sister or cousin of the victim or of the spouse, former spouse or cohabiting partner of the victim.

In 2001 new response choices had been added to the same question (the category child had been split into three: child of both the reference person and his/her partner, child of the reference person only, child of the reference person' partner only) in order to identify reconstituted families (assuming that the majority of step relationships are found between the household reference person or his/her spouse/partner and their children living in the same household).
