“…The increase in lawyer use in this study was not due to changes in rates of crashes or hospitalisations from crashes, or variations in observed crash, injury, or (measured) person factors over time: as such, it is likely to be due to other factors. These could include changes in: person factors not included in this study, such as legal consciousness (as greater legal consciousness is associated with greater capacity to resolve legal problems alone, without legal assistance; [54]); compensation scheme factors, such as the complexity and length of the claims process (as more complex and protracted processes are associated with greater legal service use; [14,16,57]); societal factors, such as attitudes towards lawyers and lawyer use (as social stigma and shame can deter claimants from engaging legal services; [58]); and regulation factors, such as legislation (as, for example, new requirements to resolve legal issues in a cost-effective, efficient, just, timely manner could increase the appeal of lawyer use; [59]). These could also include changes in the legal services market, such as increases in the number of lawyers operating in this market (as claimants are more likely to use legal services when these are readily available; [60]), and the proliferation of advertising by these lawyers (as this raises claimant awareness about the possibility of engaging legal services, and the process for doing so, as well as addressing barriers to, and reinforcing benefits of, use; [61,62]).…”
