• procedure?

  looked over history of 275 inmates after release to recidivism rate. 134 deemed suitable for MPA, released and contacted parole officers to see if they took it. (some didn't receive dosage, not accessible resource in area they live in)

  • 79 males in total received MPA, 55 didn't.

  throughout course of treatment, supervising officer received/filled in questionnaires on whether new offences had been committed.
• results?

  those offenders who received MPA committed fewer new results and no sexual results compared to other 2 groups. assessed as doing 'better' than others who didn't receive MPA
