Repertory Grid Method with Offenders: Two Case Examples with Antisocial Personality Disorder

The repertory grid is a research tool that serves both as a method and an instrument. As a method, it provides a systematic framework for exploring subjective perspectives, fostering engagement and rapport while adapting to specific contexts. As an instrument, it is coconstructed with participants, offering a personalized depiction of their internal constructs without imposing external frameworks. Despite its promise, the repertory grid has seen limited use in forensic settings. This paper reviews existing research and presents findings from two case studies involving offenders diagnosed with antisocial personality disorder. The findings support the grid's utility in providing detailed insights into personality structure, which can aid in security risk assessments and treatment planning. The grid's collaborative nature helps produce relevant personal constructs while minimizing socially desirable responses by not explicitly revealing the research goal. Its adaptability allows for customization to the researcher’s needs. However, limitations such as its complexity and the need for specialized training may hinder broader use, underscoring the need for more accessible programs or simplified educational tools.
