On the consequences of ignoring genetic influences in criminological research

Purpose

Many criminological scholars explore the social causes of crime while giving little consideration to the possibility that genetic factors underlie the observed associations. Indeed, the standard social science method (SSSM) assumes genetic influences do not confound the association between X and Y. Yet, a nascent stream of evidence has questioned the validity of this approach by revealing many criminological variables are at least partially affected by genetic influences. As a result, a substantial proportion of the literature may be misspecified due to uncontrolled genetic factors. No effort has been made to directly estimate the extent to which genetic confounding has biased the associations presented in criminological studies.

Methods

The present study seeks to address this issue by drawing on simulated datasets.

Results/Conclusions

Results suggest genetic confounding may account for a negligible portion of the relationship between X and Y when their correlation (r_yx) is larger than the correlation between genetic factors and Y (i.e., r_yx > r_yg). Genetic confounding appears to be much more problematic when the correlation between X and Y is in the moderate-to-small range (e.g., r_yx = .20) and the genetic effect is in the moderate-to-large range (e.g., r_yg ≥ .30).     

Forensic Assessment of Adults Reporting Childhood Sexualized Assault: a Lifespan Developmental Analysis

Many adults reporting childhood or adolescent sexualized assault (CSA) seek remedies through civil proceedings, thus necessitating a forensic assessment to determine the nature and extent of any psychological injuries related to such assault. Such assessments pose challenges, as CSA often occurred years earlier and may have affected not only immediate functioning but also later psychological maturation. The present paper explains how a lifespan developmental analysis can assist such assessments. The concepts of psychological development, attachment, developmental trajectory and risk and resilience can help in evaluating whether and how CSA affected normal psychological development, in determining the influence of risk factors other than CSA and in considering resiliency factors. Risk, resilience and psychological function must be examined in the domains of individual abilities and attributes, relationships and significant life activities both pre- and post-assault. Data on pre-assault risk, resilience and function can be used to estimate a “but for the assault” developmental trajectory that can then be compared to the individual’s actual developmental trajectory. This analysis, together with analysis of the severity of CSA, can assist in determining whether and how the CSA that is the basis for civil proceedings contributed to later life psychological injuries.     

Jocks, gender, binge drinking, and adolescent violence

Previous research has suggested a link between athletic involvement and elevated levels of adolescent violence outside the sport context. The present study expanded on this literature by positing differences in the sport-violence relationship across dimensions of athletic involvement (athletic participation vs. jock identity), type of violence (family vs. nonfamily), and gender as well as by examining the impact of binge drinking on the sport-violence relationship. Regression analyses using a sample of 608 Western New York adolescents indicated that (a) jock identity (but not athletic participation) was associated with more frequent violence, (b) jock identity predicted nonfamily violence (but not family violence), and (c) the link between jock identity and nonfamily violence was stronger for boys than for girls. Binge drinking predicted family violence among nonjocks only.     

Ownership of high-risk ("vicious") dogs as a marker for deviant behaviors: implications for risk assessment

This study examined the association between ownership of high-risk ("vicious") dogs and the presence of deviant behaviors in the owners as indicated by court convictions. We also explored whether two characteristics of dog ownership (abiding licensing laws and choice of breed) could be useful areas of inquiry when assessing risk status in settings where children are present. Our matched sample consisted of 355 owners of either licensed or cited dogs that represented high or low-risk breeds. Categories of criminal convictions examined were aggressive crimes, drugs, alcohol, domestic violence, crimes involving children, firearm convictions, and major and minor traffic citations. Owners of cited high-risk ("vicious") dogs had significantly more criminal convictions than owners of licensed low-risk dogs. Findings suggest that the ownership of a high-risk ("vicious") dog can be a significant marker for general deviance and should be an element considered when assessing risk for child endangerment.     

Issues surrounding a reduction in the use of internal autopsy in the coronial system

In 2003 it was estimated that 2,700 full internal coronial autopsies were performed in Queensland at a cost of approximately A$5.3 million. This large number of internal coronial autopsies (almost 95% of all matters referred to the coroner) is of concern not only due to the economic cost but also because of the public heath risks, availability of specialist staff and significant religious and cultural sensitivities surrounding internal autopsies. In 2005 the authors began research funded by the Australian Research Council (ARC) to determine if unnecessary internal autopsies are being performed in Queensland and to establish guidelines for when an internal autopsy is required. This article highlights areas of potential concern when the issue of autopsy is reviewed within the coronial system through an examination of international literature on the issue of autopsy diagnosis and error rates more generally, and through preliminary discussion of the data obtained. The article considers the role and purpose of the autopsy generally as well as within the coronial system specifically; compares diagnostic error rates in hospital autopsies with those in the coronial system; the current situation internationally with regard to internal autopsies; and finally the specific circumstances existing in Queensland.     

Suspected clozapine poisoning in the UK/Eire, 1992-2003

OBJECTIVE: Toxicological analyses are often performed to investigate suspected poisoning, but the interpretation of results may not be straightforward. We studied suspected poisoning cases 1992-2003 where blood clozapine and N-desmethylclozapine (norclozapine) were measured in order to assess the relationship of these parameters to outcome. METHODS: Samples were referred from clinicians, pathologists/coroners, or via the Clozaril Patient Monitoring Service (CPMS, Novartis). Information was gathered from clinical, post-mortem, or coroners' reports. RESULTS: There were seven fatal [five male, two female; median (range) age 28 (24-41) year] and five non-fatal [four male, one female; median age 35 (26-41) year] clozapine overdoses. The median post-mortem blood clozapine and norclozapine concentrations were 8.2 (3.7-12) and 1.9 (1.4-2.4)mg/L, respectively [median clozapine:norclozapine ratio 4.4 (2.9-5.1)]. The median plasma clozapine and norclozapine concentrations (first or only sample) were 3.9 (1.7-7.0) and 0.40 (0.30-0.70)mg/L, respectively [median clozapine:norclozapine ratio 7.6 (5.3-18)] in the remainder. These overdoses were in patients who were poorly or non-adherent to clozapine, or who had taken tablets prescribed for someone else. In 54 further people who died whilst receiving clozapine [38 male, 16 female; median age 41 (22-70) year], the median post-mortem blood clozapine and norclozapine concentrations were 1.9 (0-7.7, n = 43) and 1.4 (0-6.0, n = 39)mg/L, respectively [median clozapine:norclozapine ratio 1.5 (0.4-7.6, n = 38)]. The median post-mortem increase in blood clozapine and norclozapine as compared to the most recent ante-mortem measurement was 489 (98-5,350)% and 371 (139-831)%, respectively [median sample time before death 14 (0-30, n = 21) days]. CONCLUSION: Clozapine poisoning cannot be diagnosed on the basis of blood clozapine and norclozapine concentrations alone. The analysis of ante-mortem blood specimens collected originally for white cell count monitoring and the blood clozapine:norclozapine ratio may provide additional interpretative information.     

Adolescents’ time use: Effects on substance use,delinquency and sexual activity

Using an integration of social control theory and the routine activity perspective, adolescent time use was examined for effects on problem behaviors. We examined a wide variety of time use categories, including homework, extracurricular activities, sports time, alone time, paid work, housework, television watching, as well as indices of family time and peer time, for their effects on heavy alcohol use, cigarette smoking, illicit drug use, delinquency and sexual activity. The study employed a representative household sample of adolescents (n=606) and took into account important sociodemographic factors – gender, age, race (Black and White), and socioeconomic status. The most important predictors of adolescent problem behaviors were family time and peer time. Family time serves as a protective factor against all five problem behaviors while peer time is a highly significant risk factor for all five problem behaviors.

Toward a psychological ecology of affirmative action

Research-based knowledge of the effects of affirmative action has been little help to policy makers. That is the case because there has been no means through which to organize into a policy-relevant whole the findings that have come from a variety of disciplinary sources. A heuristic schematic of the psychological ecology of affirmative action is proposed as a step toward developing a conceptual framework that can reduce this problem. A psychological ecology of affirmative action consists of the mutual relations between policy interest groups and the procedures used to implement these policies. A critical point that the ecological framework leads to is that the nature of affirmative action procedures has a major influence on the material and subjective links between interest groups. Given that claim, the schematic is used to categorize, review, and critique the multidisciplinary research on affirmative action. From that overview, a set of general guidelines for the design of effective affirmative action programs is proposed. Finally, a call is made for a shift in the unit of policy analysis from a focus on group justice to relational justice.
