Evidence-based practice in psychology

The evidence-based practice movement has become an important feature of health care systems and health care policy. Within this context, the APA 2005 Presidential Task Force on Evidence-Based Practice defines and discusses evidence-based practice in psychology (EBPP). In an integration of science and practice, the Task Force's report describes psychology's fundamental commitment to sophisticated EBPP and takes into account the full range of evidence psychologists and policymakers must consider. Research, clinical expertise, and patient characteristics are all supported as relevant to good outcomes. EBPP promotes effective psychological practice and enhances public health by applying empirically supported principles of psychological assessment, case formulation, therapeutic relationship, and intervention. The report provides a rationale for and expanded discussion of the EBPP policy statement that was developed by the Task Force and adopted as association policy by the APA Council of Representatives in August 2005.     

The effects of the Positive Environment Program (PEP) on the behaviors of adults with profound cognitive and physical disabilities

This study evaluated the effects of the Positive Environment Program (PEP) on the behaviors of residents and staff in a state‐operated residential facility during a 2½ year period. The participants included 19 adult residents with profound cognitive and physical disabilities and 11 staff members who worked with them. Data were collected on alertness, leisure material availability, engagement, staff interactions, and resident affect during two samples of data collection six months prior to implementation of PEP. Training was then provided to staff on positive interaction skills. Following the training, researchers implemented a monitoring program and a staff incentive program. The results of this project showed improvements in staff interactions, resident interaction with leisure materials, improved levels of alertness, and increases in a ‘happiness index’. The benefits and limitations of this project as well as future research are discussed. Copyright © 2002 John Wiley & Sons, Ltd.     

Adherence to Wraparound Principles and Association with Outcomes

Maintaining fidelity to the principles of the Wraparound process in serving children with emotional and behavioral disorders is a high priority. However, the assumption that greater adherence to the model will yield superior outcomes has not been tested. The current study investigated associations between adherence to Wraparound principles, as assessed by the Wraparound Fidelity Index, second version (WFI), and child and family outcomes in one federally funded system-of-care site. Results demonstrated that higher fidelity was associated with better behavioral, functioning, restrictiveness of living, and satisfaction outcomes. No associations were found for several additional outcomes making interpretation difficult. Our study provides initial support for the hypothesis that maintaining fidelity to the philosophical principles of Wraparound is important to achieving outcomes. The study also provides support for the construct validity of the WFI as a service process measure.
