Case study reflections of an internet child abuse material offender informing the development of a proposed assessment instrument

Purpose: Internet child abuse material (I/CAM) offences negatively affect children in our own communities and in the wider virtual world. This study aims to understand the differentiation between online (internet) and offline (contact) offenders. The development of the Estimated Risk for Internet Child Sexual Offending (ERICSO), a proposed instrument for I/CAM offenders, incorporated a case study component to test on a known offender before the tool is applied to a wider sample. Design/methodology/approach: The case study approach provides a unique opportunity for researchers to consider reflections from an I/CAM offender. These insights provide unique perspectives on areas for further exploration, including suggestions for consideration in the assessment and treatment of I/CAM offenders. Findings: Mr A is a male convicted of possessing I/CAM with previous convictions for contact child sexual offending. During the development of the ERICSO, Mr A provided commentary on proposed questions based on his experiences as an offender and his communications with other offenders. Mr A’s feedback was generally consistent with current research findings, with notable suggestions in recognising the importance of differentiating between fantasy/reality, violence/voyeurism and the role technology plays in I/CAM offences. These reflections will be considered in conjunction with ongoing development and validity studies of the ERICSO to contribute to the targeted assessment and risk-relevant treatment for I/CAM offenders. Originality/value: The use of a case study in the development of a proposed assessment instrument provides a unique perspective to improve ecological validity.
