Effectiveness of a risk–need–responsivity‐based treatment program for violent and sexual offenders: Results of a retrospective,quasi‐experimental study

Purpose

Relapse prevention is an important goal in correctional settings. Although there is strong evidence for the effectiveness of certain treatment programs for juvenile offenders, those for adults lack such evidence. This study evaluated the effectiveness of a risk–need–responsivity (RNR)‐based intervention.

Methods

A quasi‐experimental, observational study design and cox regression analysis were used to compare treated violent and sexual offenders (n = 171) with untreated offenders (n = 241).

Results

Both groups were observed for an average of 7.9 years. Recidivism rates of treated offenders (11.7%, n = 20) were similar to those of control offenders (15.8%, n = 38; p = .25). When controlling for confounding variables, the hazard of recidivism in the treatment group was 5.2% lower than that in the control group. Subdividing the treatment group resulted in lower hazard ratios for offenders still in therapy when released and offenders cancelling therapy. However, none of the group differences was statistically significant.

Conclusion

Our results show that control and RNR‐based treatment groups had comparable recidivism rates with a trend towards a positive treatment effect, especially for people in outpatient treatment. However, criminal history, age at the start of follow‐up, and actuarial risk of recidivism were significantly associated with recidivism. Future research needs to apply elaborate methodological approaches to detect robust treatment effects and consider different criteria of treatment effectiveness. Furthermore, the influence of prison climate, motivational factors, intervention quality, and factors supporting the success of outpatient treatment should be considered in future studies of larger offender samples.

DOES DROPPING OUT OF SCHOOL MEAN DROPPING INTO DELINQUENCY?*

Approximately one third of U.S. high‐school freshmen do not earn their high‐school diploma on time. For African‐American and Hispanic students, this figure nearly reaches one half. The long‐term economic consequences of dropping out of school for both the student and the larger community have been well documented. It has also been argued that school dropouts put themselves at a higher risk for delinquent and criminal behavior when they leave school. Although it seems plausible that dropping out might increase the potential for delinquent conduct, another view states that dropping out is simply the final event in a long, gradual process of disenchantment and disengagement from school. Dropouts show evidence of school failure and developmental problems years in advance. It has been argued, therefore, that the actual event of finally leaving school has no causal effect on criminal or delinquent behavior because it has been so long in coming. In this article, we examine the effect of leaving school early, and the reason for dropping out, on delinquent behavior with the use of panel data models from the National Longitudinal Survey of Youth 1997 Cohort (NLSY97). Through an appeal to identity theory, we hypothesize that the effect of dropping out is not uniform but varies by the reason for leaving school, gender, and time. This conjecture receives only partial empirical support. Implications for future work in the area are discussed.     

CO‐OFFENDING AND THE DEVELOPMENT OF THE DELINQUENT CAREER*

This article examines the role of co‐offending in the development of the delinquent career. Hypotheses derived from Reiss's (1986, 1988) taxonomic theory of co‐offending are tested, using police‐reported data on the delinquent careers and co‐offending of 55,336 Canadian offenders. Support is found for a taxonomic theory and for age‐related and functional theories of co‐offending. The taxonomy consists of two types of offenders—high activity (3 percent) and low activity (97 percent)—whose co‐offending patterns differ during the teenage years but not during childhood. For low‐activity offenders as teenagers, the proportion of co‐offenses decreases with criminal experience. The rate of co‐offending by high‐activity offenders as teenagers is lower at onset than for low‐activity offenders, and it varies little with criminal experience. For both offender types, the proportion of co‐offenses decreases with age, is slightly less in males, and varies with the type of offense. For both offender types, the proportion of co‐offenses in childhood offending is greater than in the teenage years and is unrelated to the offender's age or criminal experience.     

Fast Multiplexed Polymerase Chain Reaction for Conventional and Microfluidic Short Tandem Repeat Analysis

Abstract:  The time required for short tandem repeat (STR) amplification is determined by the temperature ramp rates of the thermal cycler, the components of the reaction mix, and the properties of the reaction vessel. Multiplex amplifications in microfluidic biochip-based and conventional tube-based thermal cyclers have been demonstrated in 17.3 and 19 min, respectively. Optimized 28-cycle amplification protocols generated alleles with signal strengths above calling thresholds, heterozygous peak height ratios of greater than 0.65, and incomplete nontemplate nucleotide addition and stutter of less than 15%. Full CODIS-compatible profiles were generated using the Profiler Plus ID, COfiler and Identifiler primer sets. PCR performance over a wide range of DNA template levels from 0.006 to 4 ng was characterized by separation and detection on a microfluidic electrophoresis system, Genebench-FX^™. The fast multiplex PCR approach has the potential to reduce process time and cost for STR analysis and enables development of a fully integrated microfluidic forensic DNA analysis system.     

Classification of Glass Fragments Based on Elemental Composition and Refractive Index*

Abstract: The aim of this study was to assess the efficiency of likelihood ratio (LR)‐based measures when they are applied to solving various classification problems for glass objects which are described by elemental composition, and refractive index (RI) values, and compare LR‐based methods to other classification methods such as support vector machines (SVM) and naïve Bayes classifiers (NBC). One hundred and fifty‐three glass objects (23 building windows, 25 bulbs, 32 car windows, 57 containers, and 16 headlamps) were analyzed by scanning electron microscopy coupled with an energy dispersive X‐ray spectrometer. Refractive indices for building and car windows were measured before (RI_b), and after (RI_a) an annealing process. The proposed scheme for glass fragment(s) classification demonstrates some efficiency, although the classification of car windows (c) and building windows (w) must be treated carefully. This is because of their very similar elemental content. However, a combination of elemental content and information on the change in RI during annealing (ΔRI = RI_a?RI_b) gave very promising results. A LR model for the classification of glass fragments into use‐type categories for forensic purposes gives slightly higher misclassification rates than SVM and NBC. However, the observed differences between results obtained by all three approaches were very similar, especially when applied to the car window and building window classification problem. Therefore, the LR model can be recommended because of the ease of interpretation of LR‐based measures of certainty.     

A Fatal Shot with a Signal Flare—A Crime Reconstruction*

Abstract: A reconstruction of an incident of a fatal wounding of a football fan with a parachute flare was performed. Physical and chemical examinations of the victim’s trousers and parts of a flare removed from the wound in his leg were performed by means of an optical microscope and a scanning electron microscope coupled with an energy dispersive X‐ray spectrometer. Signs of burning were seen on the front upper part of the trousers, including a 35–40 mm circular hole with melted and charred edges. Postblast residue present on the surface of the trousers contained strontium, magnesium, potassium, and chlorine. Also the case files—the medical reports and the witnesses’ testimonies—were thoroughly studied. It has been found that the evidence collected in the case supported the version of the victim being shot by another person from a distance.     

Application of Raman Spectroscopy and Surface‐Enhanced Raman Scattering to the Analysis of Synthetic Dyes Found in Ballpoint Pen Inks*

Abstract: The applicability of Raman spectroscopy and surface‐enhanced Raman scattering (SERS) to the analysis of synthetic dyes commonly found in ballpoint inks was investigated in a comparative study. Spectra of 10 dyes were obtained using a dispersive system (633 nm, 785 nm lasers) and a Fourier transform system (1064 nm laser) under different analytical conditions (e.g., powdered pigments, solutions, thin layer chromatography [TLC] spots). While high fluorescence background and poor spectral quality often characterized the normal Raman spectra of the dyes studied, SERS was found to be generally helpful. Additionally, dye standards and a single ballpoint ink were developed on a TLC plate following a typical ink analysis procedure. SERS spectra were successfully collected directly from the TLC plate, thus demonstrating a possible forensic application for the technique.     

A 26plex Autosomal STR Assay to Aid Human Identity Testing*†

Abstract: A short tandem repeat multiplex assay has been successfully developed with 25 autosomal loci plus the sex‐typing locus amelogenin for a total of 26 amplified products in a single reaction. Primers for the loci were designed so that all of the amplicons present were distributed from 65 base pairs (bp) to less than 400 bp within a five‐dye chemistry design with the fifth dye reserved for the sizing standard. A multiplex design strategy was developed to overcome challenges encountered in creating this assay. The limits of the multiplex were tested, resulting in the successful amplification of a wide range of genomic DNA sample concentrations from 2 ng to as low as 100 pg with 30 cycles of PCR. The 26plex has the potential to benefit the forensic community for reference sample testing and complex relationship evaluation.
