社会的目标是把人送入监狱传统上被分为三个类别:惩罚、威慑和康复。康复通常被视为最政治动员的这三个原因。对许多人来说,回馈一些犯罪而言,鼓励他们康复感觉错的事——毕竟,他们不应该支付他们的债务对社会?极高的称为利率,不过,随着越来越了解,威慑就可能还不够(麦奎尔,2003)已经开始让人们相信,监禁的康复应该是一个可行的目标。康复已经再次成为感兴趣的中心在刑事司法和许多研究正在进行的变化可以鼓励它。整体康复的有效性在监狱通常被认为是参照称为统计数据。更低的利率称为往往表明,囚犯被恢复,而更高的利率显示出相反的结果。Spicer & Glicksman(2004)报告2001年英国称为利率和比较这些记录在1997年和2000年。这些统计数据表明,实际释放的两年内再判决率或社区服务的毕业典礼是53.7%,2001年已经下降了1%左右的水平之前预测的统计数据。仔细看看那些释放托管(监狱)的句子后,然而,这些数字称为率高58.2%。这意味着几乎三分之二的犯人的犯罪会再次被判入狱两年之内从监狱中被释放。虽然Spicer & Glicksman(2004)指出,显著减少的数量称为,这些减少的背景下,发生已经很高的数据。
Society's aims in putting people into prison have traditionally been placed into three categories: retribution, deterrence and rehabilitation. Rehabilitation is often seen as the least politically mobilising of these three reasons. For many people, giving back something to an offender in terms of encouraging their rehabilitation feels like the wrong thing to do - after all, shouldn't they be paying their debt to society? Extremely high reconviction rates, though, along with a growing understanding that deterrence alone may not be enough (McGuire, 2003) have begun to convince people that rehabilitation should be a viable aim of imprisonment. Rehabilitation has now, once again, become the centre of much interest within criminal justice and much research is ongoing into the changes that can be made to encourage it.The overall effectiveness of rehabilitation within prison is often judged with reference to the reconviction statistics. Lower rates of reconviction tend to suggest that prisoners are being rehabilitated, whereas higher rates suggest the opposite. Spicer & Glicksman (2004) report UK reconviction rates in 2001 and compare them to those recorded in 1997 and 2000. These statistics show that the actual rate of reconviction within two years of release or the commencement of community service was 53.7% in 2001 and had actually decreased by around 1% from the level predicted by previous statistics. Looking more closely at those released after custodial (prison) sentences, though, the figures are higher at a 58.2% reconviction rate. That means that almost two out of every three prisoners are reconvicted of an offence within two years of being released from prison. While Spicer & Glicksman (2004) point to statistically significant reductions in the number of reconvictions, these reductions are occurring against a background of already very high figures.
