Mental Illness and Offending Flashcards
What’s an issue with the CJS?
Violence at the time of arrest leads to the individual being processed through the CJS
Some prison cases should be entered into psychiatric care
Why is social class a good example of a confounding variable?
Downward social drift among the mentally ill
They may not be able to keep their job and cope with the stresses
Once their socioeconomic status has dropped they get into contact with violent subcultures e.g. living on the streets, homeless
The mentally ill tend to be of lower socioeconomic status
Removing the socioeconomic status in studies could distort the findings
Do offenders experience psychosis?
e.g. schizophrenia, schizo-affective disorder, delusional disorder
These disorders are associated with violent behaviour
More likely that a person with psychosis will commit a crime over a person without
However, researchers are still wary of suggesting that psychosis causes violence
Why is medication a confounding variable?
Psychiatric drugs are given to the mentally ill to help control their symptoms
The side effects could lead to violent behaviour
Maybe the violent behaviour is caused by the drug and not the illness
How do traumatic injuries cause violence?
Mental disorders can occur due to physical disease or traumatic injuries. Particularly, to the brain and its temporal or frontal lobes. This can encourage aggressive behaviour
What are command hallucinations?

How do the police treat those that are mentally ill?
Mentally ill people don’t have the same degree of confidence in the police

When contact is made, mentally ill people are mildly injured
