“These findings are sobering. In most <strong>of</strong> the studies described,programs struggled to enrol, engage, and retain families. Whenprogram benefits were demonstrated, they usually accrued only to asubset <strong>of</strong> the families originally enrolled in the programs, they rarelyoccurred for all <strong>of</strong> a program’s goals, and the benefits were <strong>of</strong>ten quitemodest in magnitude.” (page 9).Gomby et al. (1999) concluded that “none found significant effects on all oreven a majority <strong>of</strong> the measures employed, and many revealed no positiveeffects at all” (p 12). Despite the generally poor findings in this area, there isevidence that well-designed home visitation programmes, based on evidencebasedbest-practice, may be <strong>of</strong> use (Fergusson, Grant, Horwood, & Ridder,2005). The most persuasive support in this area comes from the work <strong>of</strong> Oldsand colleagues, who developed the Nurse <strong>Family</strong> Partnership program (Oldset al., 1998; Olds, Henderson, Kitzman, & Cole, 1995; Olds et al., 1997; Oldset al., 1994). <strong>Evaluation</strong>s <strong>of</strong> this programme have shown both long- andshort-term benefits.The strongest method for assessing long-term outcomes is to randomlyassign eligible parents to groups that do or do not receive the programme'sservices and then to follow the development <strong>of</strong> both groups over time. In thismanner, strong inferences can be made about the changes that are seen inthe group that are assigned to the programme 5 . This approach has recentlybeen employed by Fergusson and colleagues in looking at a group <strong>of</strong> at-riskfamilies in Christchurch (Fergusson, Grant et al., 2005; Fergusson, Grant,Horwood, & Ridder, 2006).The study used a RCT design in which 220 families receiving the Early Startprogramme were contrasted with a control series <strong>of</strong> 223 families not receivingthe programme. Families were enrolled in the programme after populationscreening conducted by community health nurses. This evaluation suggestedthat the Early Start programme failed to lead to parent- and family-related5 The problems inherent in this type <strong>of</strong> research design have been discussed by (A. M.Tomison, 2000).21
