This article examines the prevalence of moderate and severe problem gambling in a sample of 254 incarcerated Canadian male federal offenders (completion rate of 39.0%). The prevalence of disordered gambling was measured using the PGSI, DSM-IV-TR, and SOGS that yielded estimates of 9.4%, 6.3%, and 13.0%, respectively. Severe problem gamblers were significantly more likely to have committed income producing offences, but were neither more nor less likely than other offenders to have committed violent offences. The majority of severe problem gamblers (65.2%) and a fifth of the moderate problem gamblers (20.0%) reported that their criminal activity was a result of their gambling (e.g., to pay off debts). Based on these findings there appears to be a need to offer problem gambling treatment services to offenders in order to help them break the cycle of gambling, debt and crime.

This paper reports on the results of a multi-site survey of gambling behaviour and gambling problems amongst offenders in correctional institutions in Ontario, Canada, conducted between 2008 and 2011. A total of 422 (completion rate 61.5 %) incarcerated offenders (381 male and 41 female) took part in the study including 301 federal offenders and 121 provincial offenders. Based on the Problem Gambling Severity Index of the Canadian Problem Gambling Index (CPGI/PGSI) the prevalence rate of severe problem gambling was 8.9 prior to incarceration and 4.4 % during incarceration. These numbers are substantially higher than rates found among the general public. Thirty-four percent of the sample reported gambling in prison. Half of those who suffered from gambling problems before incarceration continued to have gambling problems during incarceration. People with problems related to slot machines prior to incarceration reported fewer gambling problems during incarceration compared to other problem gamblers.

The treatment of violent offenders has evolved in recent years, shifting from interventions focused on anger management to those incorporating social information processing skills. The present study was a multimethod evaluation of one such program, the Persistently Violent Offender program. A total of 256 Canadian male violent offenders participated in the study; 70 Persistently Violent Offender program completers were compared to two control groups (n(1) = 33, n(2) = 105) who completed an alternate program and to 48 offenders who failed to complete either program. Results demonstrate few differences among groups in terms of changes on measures of treatment targets, involvement in institutional misconducts, and postrelease returns to custody, thus demonstrating that the Persistently Violent Offender program was superior to neither the alternate program nor program noncompletion. These results are discussed in light of the findings from two more promising recent evaluations of similar programs.

Sixty incarcerated rapists were subtyped according to the Massachusetts Treatment Center Rapist Typology as either “nonsexual” (i.e., the opportunistic and vindictive subtypes) or “sexual” (i.e., the nonsadistic and sadistic subtypes). Subjects were then tested using the circumferential penile plethysmograph, assessing their erectile responses to verbal descriptions of consenting sex and rape. Additionally, the Psychopathy Checklist-Revised was scored for each subject, and institutional files were summarized and coded. The index offenses committed by the nonsexual subtypes were more violent and resulted in greater victim damage; the offenses of the men in the nonsexual subtypes were more likely to be impulsive; the men in the sexual subtypes were more socially isolated at the time of the offense. Relative sexual arousal to rape descriptions was greater among the sexual subtypes than among the nonsexual subtypes. These results are discussed in terms of two separate cognitive-behavioral processes leading to rape.
