Home visiting intervention for vulnerable families with newborns: follow-up results of a randomized controlled trial

OBJECTIVE: This study aimed to: (1) Assess the community utility of a screening tool to identify families with child abuse or neglect risk factors in the immediate postnatal period (2) Determine the social validity and effectiveness of a home visiting program using community child health nurses and offering social work services for identified families, and (3) Identify factors in the immediate postnatal period associated with the child's environment that predict poor adjustment to the parenting role. METHOD: A randomized controlled trial using a cohort of 181 families was undertaken to evaluate the impact of a home visiting program. Mothers were recruited in the immediate postnatal period and allocated either into the home visiting program or into a comparison group. The research design required self-identification into the study by providing positive responses to a range of risk factors. A repeated measures design was used to test parenting stress and maternal depression from the immediate postnatal period to 12-month follow-up and physical child abuse potential to 18-month follow-up. To test whether measures taken in the immediate postnatal period were predictive for poor adjustment to the parenting role, a linear regression model was used. RESULTS: The screening procedure was shown to have utility in the context of recruitment to a research trial and mothers were willing to accept the home visiting program examined by this study from the immediate postnatal period. From as early as 6 weeks the program demonstrated ability to impact positively on maternal, infant, family, and home environment variables (testing 90 randomly allocated intervention vs. 91 comparison families). At follow-up, parental adjustment variables were not significantly different between groups (testing the remaining 68 (75.5%) intervention vs. 70 (76.9%) comparison families) and home environment assessment scores had converged. Predictive analysis of factors measured in the immediate postnatal period revealed an absence of any predictive value to demographic characteristics, which secondary prevention efforts typically target. CONCLUSIONS: Follow-up evaluation did not demonstrate a positive impact on parenting stress, parenting competence, or quality of the home environment confirming the need to test early program success on longer term outcomes. Further, thestudy not only demonstrated that there was a relationship between maternal, family and environmental factors identified in the immediate postnatal period. and adjustment to the parenting role, but also challenged demographic targeting for child abuse and neglect risk. At the same time, the immediate postnatal period presented an exciting window of opportunity to access high-risk families who may otherwise have become marginalized from traditional services.

Expectancies as mediators in the differential-reward conditional discrimination performance of pigeons

In a series of within-subject experiments employing a two-choice delayed conditional discrimination task, pigeons chose correctly more often when kind of correct choice and kind of reinforcer were perfectly correlated than when uncorrelated. Correct choice behavior fell to chance levels when the correlation was reversed or when it was removed by using only one kind of reinforcer. Implications for mediation theories are discussed, with the conclusion being that, although the possibility that instrumental mediators are present in this situation cannot be dismissed, the overall pattern of results indicates that classical mediators are of principal importance in this type of task.     

‘I understood the complexity within diversity’: preparation for partnership with families in early childhood settings

‘Partnership between parents and teachers’ is a taken-for-granted feature of the philosophy and practice of early childhood education. Yet, the literature suggests this rhetoric belies a more complex and problematic reality for teachers. Making connections with the families and communities they will serve may help teacher education students confront understandings of the realities of family lives and assist them to prepare for their professional responsibilities. Teacher education literature suggests that supported field experiences may assist student teachers to examine their beliefs and reflect on their practices with families. This paper reports on the experiences of student teachers who undertook a community placement in order to interact with children and families outside their normal range of teaching practice experience. Three themes of changes in student learning are discussed: (1) beliefs about partnerships; (2) notions of complexities within diversity; and (3) developing relationships with diverse families. The paper argues that the change in placement setting prompted student reflection in relation to these themes and shifts in beliefs, towards more authentic and complex understandings of partnership.
