In total, between juvenile and adult institutions, trevor has spent over 20 years of his life incarcerated. his family cannot understand why he continues to commit crime. they are concerned that he will not be able to remain a law-abiding citizen. what does the research say about the effect of incarceration and an offender's likeliness to repeat criminal behavior

the answer is  Most offenders are rearrested within 3 years of their release from prison
According to a statistic provided by The national institute of Justice, around 76% person of the offenders would most likely to return within that time period.
This happens because prisons usually do not possess enough programs to change/cure offenders' tendency to repeat their risky behaviors.
