“…Another study in progress offering several alternative approaches to intervening with parents may provide a useful comparison because of its experimental design. Following the model of a successful program to evaluate different therapeutic approaches for school children (Kolvin et al, 1981), three types of prevention are being compared for mothers of pre-school children (Nicol, Stretch, Davidson & Fundudis, 1984;Koziarski, Hodgson & Nicol, 1986).
