The stereotype that goes hand in hand with mental illness, which seems to have improved over the years, is still pervasive. Teplin, Abram, and McClelland (1994) assert that people in general believe that people with mental illness are more likely to commit violent crimes compared to those without mental illness. In their study, they seek to find evidence for this claim – to find out whether having a mental illness increases the likelihood of violent crime and recidivism after release from prison. This author seeks to discover the same thing using similar data to find out if there is a link between violent crime and mental illness. The data collected in Teplin, Abram, and McClelland's (1994) research was conducted in the Cook County Jail in Chicago over a six-year period. over a period of one year, using interview techniques during the intake process of 728 inmates. They then followed the participants for six years by monitoring their criminal records. What sets this research apart from others is that it used a prison population rather than a prison population. Typically, once in prison, the time spent there is long, whereas in prison, the length of incarceration is usually much shorter because inmates are in prison for minor offenses or awaiting trial. In any case, there is a greater delay and more possibilities to obtain diverse data in the long term. Teplin, Abram, and McClelland (1994) used a prison control group as well as the mentally ill population, however, there had to already be a control group. established diagnosis of mental illness among those included in the sample. They used the independent variable of violent hallucinations and delusions as a dependent variable that was only counted when not induced by alcohol or drug use.
