ABSTRACT
ADHD has been recognised a disorder which appears across the lifespan (Kessler et al., 2006) with an estimated prevalence of 2.5% of adults meeting the criteria for a diagnosis (Simon, Czobor, Balint, Meszaros & Bitter, 2009). Furthermore, it is associated with early onset offending (Mohr-Jensen & Steinhausen, 2016) and higher rates of reoffending in adults (Young, Wells & Gudjonsson, 2011). Young et al. (2018) note this amounts to approximately 2.8 million prisoners worldwide meeting the diagnostic criteria for ADHD. However, it is also noted that barriers exist in terms of people accessing diagnosis and treatment for ADHD. Thus, the purpose of this chapter is to highlight how bias may contribute to these barriers and provide practical suggestions for how these may be overcome.
