Samenvatting

Circles of Support and Accountability (COSA) provide re-integrating
sex offenders with a group of trained volunteers who support
this rehabilitation process. Effect studies show promising results in
reduction of recidivism. This study provides a theoretical underpinning
and empirical validation of the COSA intervention model,
based on a grounded theory analysis of 38 circle narratives, reflecting
the experiences of 21 circles. Four circle functions appear to be
essential, with inclusion being most important. Inclusion is serving
basic human needs and is motivating the sex offender to allow
monitoring and being held accountable. Program integrity and a
positive group development are essential preconditions for circle
effectiveness.
