Evaluating the impact of evidence-based practice and policy in public health: A case study on parent-child interaction therapy
Abstract
The purpose of this study was to explore the evidence-based practice movement and
its implications for the realm of public health. The paper first described the evidence-based
practice movement and examined its pros and cons, including some of the barriers to
implementation. A case study on Parent-Child Interaction Therapy (PCIT), an evidence-based
practice (EBP), was then conducted to examine whether an EBP resulted in better outcomes
than treatment as usual for clients from one agency in Durham. The findings from the
data analyses showed that PCIT did not necessarily result in better outcomes than
treatment as usual based on the AAPI results. PCIT also did not serve all racial groups
equally well. Latino families achieved greater improvement on most subscales from
treatment as usual than from PCIT, whereas African American and Caucasian clients
achieved more improvement from PCIT than from the comparison treatment. Analysis of
satisfaction surveys showed that PCIT clients expressed greater satisfaction than
comparison treatment clients in two aspects. PCIT clients tended to believe that their
providers were more knowledgeable and that their providers respected the family’s
way of doing things. No significant provider effects could be observed from the data
analysis.
