This meta-analysis was conducted to examine predictors of two indicators of inmates’ adjustment to prison life: institutional infractions and health care utilization. Focusing on male prisoners, the final data set consisted of 90 studies and produced 1,815 correlations. Predictors were grouped into personal and contextual characteristics. Regarding institutional infractions, the strongest personal predictors were prior prison misconduct, aggressiveness, impulsiveness, antisocial traits, institutional risk, and younger age. At the contextual level, higher infraction rates were observed in prisons with more gang activity, and in prisons housing more inmates and a larger proportion of maximum security inmates. Major correlates of health care utilization were prior mental health problems, older age, and physical symptoms. Moderator effects were observed for prison sample size, sample selection, length of follow-up, geographic location, and type of analysis. These findings may help to improve prison classification procedures to optimize prisoners’ management and treatment.

Different studies have proposed that batterers can be classified into distinct groups according to psychopathology, violence severity and frequency. The aim of the current study was to define a data-based batterer's typology and its implications for rehabilitation. Data were collected from 187 male sentenced for intimate partner violence –111 of them to prison and 76 to community service. A cluster analysis supported a three-cluster solution: non-pathological (NP, 40%), antisocial/violent (AV, 27%) and disturbed batterers (DB, 33%). Subsequent analysis showed that AV batterers were profiled through the perpetration of physical and psychological violence, antisocial behaviour, deviant lifestyle, criminal records, inter parental violence and drug abuse; DB batterers, were profiled through behaviours of psychological violence, physical aggression and hostility, clinical symptomatology (e.g., somatisation, depression, anxiety, paranoid ideation), criminal records, antisocial behaviour, and a deviant lifestyle; and NP batterers were not profiled through any of the variables related to criminality and recidivism. Multinomial logistic regression supported different logistic models for batterer types in terms of psychopathological, antisocial and perpetrated violence-type variables. Implications of batterer typology on treatment are discussed

The aim of the present study was to examine the psychometric properties of the Reactive–Proactive Aggression Questionnaire (RPQ) among a forensic sample of incarcerated male juvenile offenders (N = 221). The Portuguese version of the RPQ demonstrated promising psychometric properties, namely, in terms of factor structure, internal consistency, convergent validity, discriminant validity, and concurrent validity that generally justifies its use among this population. Statistically significant associations were found with conduct disorder, age of criminal onset, age of first problem with the law, crime seriousness, physical violence use in committing crimes, alcohol use, cannabis use, cocaine/heroin use, and having unprotected sex. The findings provide additional support for the extension of the RPQ across different cultures, ethnic groups, and samples.

The main aim of the present study was to examine the psychometric properties of the Inventory of Callous-Unemotional Traits (ICU) among a sample of incarcerated male Portuguese juvenile offenders (N = 221). Based on this sample, the Portuguese version of the ICU demonstrated promising psychometric properties, namely, in terms of factor structure, internal consistency, convergent validity, discriminant validity, and concurrent validity that generally justifies its use among this population. Statistically significant associations were found with conduct disorder, age of criminal onset, crime seriousness, physical violence use in committing crimes, alcohol use, cannabis use, and cocaine/heroin use.

Intimate partner homicide/attempted homicide are the most serious outcome of intimate partner violence. Thus, in this study, conducted in Portugal, we sought to compare perpetrators of severe violence with those who perpetrate less severe acts of violence as well as to identify predictors for severe violence. Sample was constituted by 50 men convicted for marital homicide or attempted homicide and 137 men convicted for domestic violence. Results show that although both perpetrators of severe and less severe violence share some characteristics, significant differences were found among them. The use of weapons, separation/break-up, and high socioeconomic status (SES) significantly increased the likelihood of a man to commit severe violence. Prior violence, aggression, and medium SES decreased significantly the probability of an individual to perpetrate severe violence. These findings reinforce the assumption that severe and less severe forms of violence can be discrete phenomena and underscore the importance of conducting accurate risk assessments.
