Professional guidelines consistently advise evaluators to include only relevant information, and exclude irrelevant information, when crafting forensic mental health reports. However, such guidance is more general than specific, and many forensic reports include background information that is not directly relevant to the psycholegal question. In this study, we considered three types of defendant information for which the competency literature provides no clear guidance for inclusion or exclusion: defendant criminal history, substance use history, and race and/or ethnicity. We examined the frequency with which evaluators report these types of information in a statewide sample of Virginia court-ordered competence reports (N = 1,126). We sought to assess common reporting practices, determine whether such practices varied among evaluators, and identify potential explanations for differing reporting practices. Results revealed no consensus among evaluators regarding what types of information should be routinely included in competence reports. Reports were slightly more likely to include substance use information (57.6% of reports) and criminal history information (57.5%) than race/ethnicity information (52.0%). However, there was significant variability in reporting practices among evaluators, especially regarding the inclusion of defendant race/ethnicity (68.6% of variability explained by evaluator differences). Overall, many reporting practices appeared to be best explained by evaluator habit or convention, rather than relevance, although alternative explanations are discussed. Findings highlight the need for more definitive guidance on the topic and future research exploring the potential impact of reports that include irrelevant (and potentially prejudicial) information.
