PURPOSE
The need for random assignment in sexual offending programme evaluation is clear. Decades of high dependence on weak-inference methodology, that of observational studies, has inhibited professional agreement regarding the effects of programmes. Observational studies have a place in evaluation research when more rigorous scientific designs precede them, as occurs in neighbouring fields of drug development and health. If, however, observational studies remain the only method used to evaluate sexual offending programmes, the field will continue to endure uncertainty with confident causal inferences regarding their effects remaining elusive. The paper aims to discuss these issues.
Design/methodology/approach
The paper takes the form of a literature review and discussion.
Findings
The case for random assignment is made alongside a rebuttal of arguments against their use.
Originality/value
This is an original look at the need for random assignment in sexual offending programme evaluation taking into account existing studies and discussion topics.
