The movement towards the provision of evidence-based services has become increasingly important to psychological practice (CPA Task Force on Evidence-Based Practice of Psychological Treatments, 2012; Levant, 2005). One of the key components of this movement is the summarizing and dissemination of important findings to key stakeholders for interventions using techniques such as meta-analysis. Meta-analyses are typically based on reviews of the published literature on a particular topic, but increasingly researchers are acknowledging the importance of examining and including unpublished, grey literature in their reviews in presenting an accurate picture of a body of literature (Hopewell, McDonald, Clarke, & Egger, 2008; McAuley, Pham, Tugwell, & Moher, 2000). However, the inclusion of grey literature in meta-analyses and reviews remains controversial (Coad, Hardicre, & Devitt, 2006; Martin, Perez, Sacristan, & Alvarez, 2005; Seymour, 2010). A number of reviews of behavioural parenting interventions have been conducted. The body of literature in this area continues to grow quickly, and recent meta-analyses in this area have examined only subsets of the literature, thus necessitating an overall examination of all available literature in this area: published and unpublished. The present meta-analysis synthesized the results of 42 published and 6 unpublished behavioural parenting intervention studies conducted between 1966 and 2011. In the first manuscript, treatment efficacy was examined with respect to three different outcomes (parent behaviour, child behaviour, and parent adjustment). I also examined the differential effects of six moderator variables in two categories: child characteristics (child formal diagnostic status and child age) and methodological characteristics (overall quality, comparison group, experimenter allegiance, and publication status). In the second manuscript, I examined both the advantages and challenges of including grey literature in meta-analyses, and explored the use of an innovative search program. I also explored the influence of the inclusion of grey literature on outcomes, including whether effect sizes, sample homogeneity, and publication bias indices are affected by the inclusion of grey literature. Results of the present study confirm the efficacy of behavioural parenting interventions on parent behaviour, child behaviour, and parent adjustment outcomes. Further, I extend the knowledge base through the inclusion of recent reports, grey literature, searches of basic search engines such as Google and Yahoo, and the examination of previously unexplored moderator variables. My results underline the importance of consistent reporting practices in the field and their impact on the availability of evidence for policy-makers, administrators, researchers, clinicians and consumers. I also discuss the implications of these findings for the provision of evidence-based services for parents, knowledge translation, and grey literature.
