The relationship between trauma and violence in a jail inmate sample

Research suggests there is a link between trauma and violence, although the nature of the relationship is rather equivocal. This study explored this relationship by examining self-reported trauma as a predictor of self-reported violence in 93 jail inmates. Ninety-six percent of the sample reported experiencing a traumatic event, and 67% reported having been violent during the year preceding incarceration. Inmates reporting trauma were more than twice as likely to report having been violent than nonviolent. Stepwise multiple regression analyses suggested traumatic events, as a combined model, significantly contributed to violence perpetration. In addition, witnessing serious violence predicted perpetration of violence. Implications and limitations of the present study are discussed.     

Pornographic exposure over the life course and the severity of sexual offenses: Imitation and cathartic effects

Purpose

Extant scholarship has examined pornography's putative link to the commission of sex crime. Yet, virtually no research speaks to whether an offender's exposure to pornography during many different stages of life elevates the violence of a sex offense. The current study addresses this gap.

Methods

Using retrospective longitudinal data, we systematically investigate the effect of offender pornography exposure during adolescence, adulthood, and immediately prior to the offense on the level of physical injury as well as the extent of humiliation experienced by sex crime victims.

Results

Findings indicate that adolescent exposure was a significant predictor of the elevation of violence—it increased the extent of victim humiliation. Results also suggest a tempering, or cathartic effect of pornography—using pornography just prior to the offense was correlated with reduced victim physical injury. No effects, however, were observed for adult pornography exposure.

Conclusion

Pornography use may differentially influence offenders’ propensity to harm or degrade victims over the life course.     

Stereochemical Analysis of Methorphan Using (−)‐Menthyl Chloroformate

Abstract: Forensic laboratories around the world have seen an increase in the number of drug seizures containing methorphan. Levomethorphan is a narcotic and a controlled substance, and its enantiomer dextromethorphan is an antitussive agent used in over‐the‐counter medications. For the forensic analysis of seized drugs containing methorphan, it is important to report the stereochemical composition of the drug. Ideally, a method based on common forensic laboratory instrumentation is desirable. The use of the chiral derivatizing agent (?)‐menthyl chloroformate followed by routine gas chromatography–mass spectrometry analysis of the derivative was shown to successfully determine the stereochemical composition of methorphan. This approach was applied to a street seizure containing methorphan proving that it was pure dextromethorphan. The derivatives of dextro‐ and levomethorphan were subjected to mass spectroscopic and nuclear magnetic resonance analysis, which confirmed that the structure of the derivatives remained unchanged as a result of the derivatization process.     

Early criminal recidivism among mentally disordered offenders

Criminal recidivism was studied during 2 years in a Swedish population-based cohort (N = 318) of mentally disordered male offenders who had undergone a pretrial forensic psychiatric investigation, been convicted in subsequent trials, and been sentenced to forensic psychiatric treatment (FPT; n = 152), prison (n = 116), or noncustodial sanctions (n = 50). Recidivism was analysed in relation to index sanctions, levels of supervision, diagnoses, and criminological factors. Significantly lower recidivism in the FPT group was related to lower crime rates during periods at conditional liberty in this group alone, and recidivism was significantly more common among offenders with at least one of the two diagnoses of substance abuse disorder and personality disorder than among those with psychotic or other mental disorders alone. Age at index crime and number of previous crimes emerged as significant predictors of recidivism. The results of this study suggest that the relapse rates depend as much on level of supervision as on individual characteristics.     

Adolescent self-image as a mediator between childhood maltreatment and adult sexual offending

Purpose

The link between maltreatment and offending has been well established in the literature, with research examining the etiology of criminal behavior consistently documenting the negative effects of experiencing trauma early in life. Theoretically, ideas behind the cycle of violence hypothesis have greatly contributed to our understanding of this connection; however, there is a lack of understanding of the mechanisms underlying this relationship. We address this research gap by examining the mediating role that adolescent mental health, particularly self-image, plays in the relationship between child maltreatment and subsequent adult sex offending.

Methods

We utilize retrospective data from a sample of incarcerated sex offenders at a maximum security penitentiary located in Canada (N = 565).

Results

Results indicate that poor self-image in adolescence partially mediates the relationship between child maltreatment and the extent of sex offending in adulthood.

Conclusions

Implications for research, theory, and policy are discussed.     

Sex industry exposure over the life course on the onset and frequency of sex offending

Purpose

Research has examined pornography use on the extent of offending. However, virtually no work has tested whether other sex industry experiences affect sex crime. By extension, the cumulative effect of these exposures is unknown. Social learning theory predicts that exposure should amplify offending. Separately, the developmental perspective highlights that the timing of exposure matters.

Methods

Drawing on retrospective longitudinal data, we first test whether exposure during adolescence is associated with a younger age of onset; we also examine whether adulthood exposure is linked with greater frequency of offending.

Results

Findings indicate that most types of adolescent exposures as well as total exposures were related to an earlier age of onset. Exposure during adulthood was also associated with an overall increase in sex offending, but effects were dependent on “type.”

Conclusion

There are nuances in the effect of sex industry exposure on offending patterns. Implications of results are discussed.
