Cross-national comparison of homicide: Age/sex-adjusted rates using the 1980 U.S. homicide experience as a standard

Cross-sectional studies of crime have typically relied on crude crime rates when making comparisons between countries. Crude rates control for population size but implicitly assume that all members of the population are equally at risk. Empirical studies have shown that, cross-nationally, risk varies by age and sex. Standardization of crime rates removes the confounding effects of variable age and sex population distributions. Since age/sex-specific crime rates are generally unavailable for many countries, the method of indirect standardization is the most desirable technique. Age/sex-adjusted homicide rates for 76 countries are presented, and two comparative measures are suggested. It is shown that while the United States has a higher homicide rate than all but 15 countries; in most cases, the magnitude of the difference, not controlling for age/sex differences, is overestimated. Crude rates underestimate differences between the United States and countries with higher rates of homicide.     

Effect of test administration set on the Psychological Inventory of Criminal Thinking Styles (PICTS)

The Psychological Inventory of Criminal Thinking Styles (PICTS) was administered to 160 male prisoners on admission to a medium-security federal correctional facility. A total of 106 of these inmates completed the PICTS a second time 6 months later in a routine follow-up of the intake PICTS; the other 54 inmates completed the PICTS a second time approximately 6 months later during the initial session of a psychological group. Results showed that inmates participating in the psychological group were less defensive and endorsed more criminal thinking items on the second administration of the PICTS, whereas inmates participating in the routine follow-up were more defensive and less likely to endorse criminal thinking items on the second PICTS. Despite a general increase in the magnitude of PICTS scores for program participants, the overall pattern of scale elevations (correlations between scales and high-point pairs) was comparable across the two groups.     

Criminal thinking as a moderator of the perceived certainty–offending relationship: age variations

ABSTRACT

The purpose of this study was to determine whether the perceived certainty of punishment and general criminal thinking interact and whether the effect varies as a function of age. Data from all 1354 members (1170 males, 184 females) of the Pathways to Desistance study were used to test whether perceived certainty, general criminal thinking, and their interaction predicted subsequent offending during late adolescence (16–18 years of age) and emerging adulthood (20–22 years of age). The results showed that while perceived certainty and general criminal thinking failed to interact at age 17, general criminal thinking moderated the effect of perceived certainty at age 21. During emerging adulthood, offending was more common and varied in young adults with low certainty perceptions and high criminal thinking than it was in emerging adults with high criminal thinking and high certainty perceptions or low criminal thinking and either high or low certainty perceptions.     

Crime Continuity and Psychological Inertia: Testing the Cognitive Mediation and Additive Postulates with Male Adjudicated Delinquents

Objectives

Crime continuity is one of the best documented and least understood aspects of criminal behavior. Psychological inertia, the notion that cognitive variables mediate the relationship between earlier and later expressions of the same behavior, was tested as a possible explanation for crime continuity.

Methods

The cognitive mediation and additive postulates of the psychological inertia theorem were tested in a path analysis using self-report data from 1170 male delinquent members of the Pathways to Desistance study (Mulvey in Paper presented at the American Society of Criminology Annual Meeting, Chicago, IL, 2012). Wave 1 delinquency served as the independent variable, Wave 3 delinquency served as the dependent variable, Wave 2 outcome expectancies for crime, self-efficacy, general criminal thinking, and social capital served as the mediator variables, and 12 different baseline measures from criminological theory served as control variables in this study.

Results

General criminal thinking and low self-efficacy successfully mediated the relationship between past and future offending after age, race, early behavioral problems, peer criminality, family criminality, parental knowledge and monitoring, parental hostility, routine activities, measured intelligence, and precursors for each of the mediators were controlled. Social capital (cumulative disadvantage), by comparison, failed to mediate crime continuity in this study.

Conclusions

Effective cognitive mediation of the relationship between Wave 1 offending and Wave 3 offending and evidence that the effect may be additive offer preliminary support for the cognitive mediation and additive postulates of the psychological inertia theorem. Practical implications of these results include the need to routinely assess cognitive factors in criminal populations and target these factors for intervention.
