The GLM is a strengths-based approach to offender rehabilitation, and is therefore premised on the idea that we need to build capabilities and strengths in people, in order to reduce their risk of reoffending. According to the GLM, people offend because they are attempting to secure some kind of valued outcome in their life. As such, offending is essentially the product of a desire for something that is inherently human and normal. Unfortunately, the desire or goal manifests itself in harmful and antisocial behaviours, due to a range of deficits and weaknesses within the offender and his/her environment. Essentially, these deficits prevent the offender from securing his desired ends in pro-social and sustainable ways, thus requiring that s/he resort to inappropriate and damaging means, that is, offending behaviour.
