Additional primary prevention programs for parental depression have focused on the period from conception through age 5, although most address parents with infants rather than those with toddlers (Bee et al., 2014;Craig, 2004). Selective primary prevention of depression among parents has been tested most frequently in the perinatal period, with most programs targeting high-risk groups, such as mothers with preterm infants or those at increased risk for postpartum depression (Ammerman et al., 2013; Beardslee et al., 2010; Dennis, 2014; Silverstein et al., 2011). The perinatal period appears to be an effective time to reach a broad population of parents.
