Abstract

Many practices available for use in health service psychology are ineffective or harmful. How we describe these practices is important to scientific discourse and science communication with policy-makers and the general public. The label “pseudoscience” is typically applied in these cases, though the meaning of pseudoscience varies widely creating a quagmire for transparent and accurate communication. To clarify this issue, we review several prominent definitions of pseudoscience as well as consider how the term is used amongst psychology scholars and science-communicators. We define two additional terms adapted from the medical literature, contemporary and alternative psychotherapies and low-value practices, and discuss their strengths and limitations. Finally, we recommend the broader category of low-value practices for use due to its definitional clarity, lack of competing definitions, and potential for clarifying research programs.
