The Psychology Service forms part of the Regimes Directorate of the Irish Prison Service. It provides mental health services to prisoners (coping with imprisonment, depression, anxiety etc.) and helps offenders address factors that put them at risk of re-offending (anger, substance abuse, sexual and violent offending etc). The Service is heavily involved in the delivery of the Building Better Lives programme for sex offenders in Arbour Hill and a similar programme for violent offenders in Wheatfield Prison.
There are 21 psychologists working in prisons – 1 Head of Service, 6 Senior Psychologists and 14 Psychologists.
