Confirmatory factor analysis of a four-factor model – with ‘repression’, 'support’, ‘growth’ and ‘group atmosphere’ as first order factors – and ‘overall group climate’ as a second order factor showed an adequate fit to the data, indicating construct validity of the PGCI. Cronbach’s alpha reliability coefficients were good for all factors. The PGCI is a parsimonious instrument, enabling future research on group climate in youth prisons and secure forensic psychiatric institutions. The instrument can be used as an assessment tool for judicial interventions that use group climate to improve outcomes in delinquent youth and adult delinquents receiving treatment for psychiatric problems. cAmsterdãod2011tThe Prison JournalvVol. 91, nº 2x15527522 aCENTRO EDUCATIVO aPSIQUIATRIA PENITENCIÁRIA aREINSERÇÃO SOCIAL aREINCIDÊNCIA aAVALIAÇÃO aESTUDOyHOLANDA a343.8 avan der HelmbG.H.P. cLeiden Professional University (School of Social Studies) 4070a Stamsb G.J.J.M cUniversity of Amsterdam (Department of Forensic Child and Youth Care Sciences). 4070 aVAN DER LAANbPeter H. aPTgRPC j343.8HEL 104343_000000000000000_8HEL52024-09-25696429480464aDGRSPcDGRSPfDGRSP9642k343.8HELn2024-09-25o0rMOxOferta
