Research on Improving Outcomes and Reducing Costs of Psychological Interventions: Toward Delivering the Best to the Most for the Least

Abstract

Treatment and prevention efforts guided by psychological theory, research, and practice can have outcomes of greater value than the resources consumed by those efforts—and outcomes superior to those attainable by other means, often at lower costs. How can we make this hope true more often, for more of the clients who need our services, despite severe resource constraints? Routinely reporting the costs, effectiveness, and benefits of psychological interventions from client, practitioner, and societal perspectives is only a beginning. We also need to use descriptive and inferential statistics to measure, report, and analyze the cost-effectiveness and cost-benefit of our interventions to discover the strongest determinants of intervention costs and outcomes. The emerging literature on cost-inclusive research in psychology suggests that delivery systems are one primary determinant of costs and outcomes of most interventions, as are the psychological techniques applied.
