Inter-rater reliability of dynamic risk assessment with sexual offenders

Abstract

This paper describes the inter-rater reliability of the Structured Assessment of Risk and Need (SARN, formerly known as Structured Risk Assessment). The SARN is a structured framework for identifying sexual offenders’ dynamic risk factors. The SARN comprises 16 dynamic risk factors, categorized into four domains: Sexual Interests, Distorted Attitudes, Socio-Affective Functioning and Self-Management. Two studies, utilizing three samples, are reported. Study 1 examined the inter-rater reliability of four SARN cases with a sample of seven expert raters. Results indicated high inter-rater reliability amongst these participants. Study 2 examined the reliability of SARN with two samples who had received training before supplying inter-rater data (N=88). Results provided some support for the reliability of SARN. However, strength of reliability was dependent upon the method of analysis applied (percentage agreement, Cohen's Kappa, intra-class correlation coefficients). These results are discussed in terms of their clinical and methodological implications.     

Components underlying sex offender treatment refusal: an exploratory analysis of the Treatment Refusal Scale—Sex Offender version

Abstract

Approximately half of sexual offenders in prison and community settings refuse to participate in sex offender treatment programmes; however, the reasons for this remain largely unexplored. This pilot study used the previously untested Treatment Refusal Scale—Sexual Offender Version in an English prison, with 72 adult males (63 treatment accepters and nine treatment refusers) imprisoned for sexual or sexually motivated offences. Principal factors analysis revealed three factors within the scale: “pressured to take part in programmes”; “fear of negative effects”; and “programme is not relevant to/appropriate for me”. Treatment refusers scored more highly than treatment accepters on the first and last components, while there was no statistically significant difference in the scores of the two groups on the “fear of negative effects” component. Suggestions for further development of the scale are discussed, along with the practice implications of these findings.     

Reconviction following a cognitive skills intervention: An alternative quasi‐experimental methodology

Purpose. Enhanced Thinking Skills (ETS) has been the most widely delivered cognitive skills programme in the prisons of England and Wales. Four quasi‐experimental outcome studies have produced mixed results, a qualitative survey of offenders’ and facilitators’ experience on the programme proved useful in programme refinement, and a study using random allocation provided evidence that ETS impacts significantly and positively on short‐term attitudinal change. This study aims to make a further contribution, using another methodology, to the accumulation of evidence. Methods. This was a real‐world evaluation, comparing the reconviction outcomes of the population of 17,047 ETS participants in custody from 2000 to 2005 with a national cohort of 19,792 prisoners released over the same period. Results. Overall, prisoners who had attended ETS were found to reoffend at a rate 6.4 percentage points less than the cohort (rising to 7.5 percentage points for programme completers) and 9.5 percentage points less than the predicted rate. In all but the very highest risk group and in every sentence length band, the reoffending outcomes for ETS participants were significantly better than for prisoners in the cohort. Conclusions. It is argued that this non‐experimental methodology makes a contribution to the ‘What Works’ evidence.     

Evaluating the work of Australia's Family Relationship Centres: Evidence from the first 5 years

Family Relationship Centres (FRCs) have been described as a centerpiece of Australia's 2006 family law reforms. This paper places these centres in the larger context of the reforms and their commitment to providing community‐based family services in the family law area. The paper also examines the empirical evidence regarding FRCs' use and effectiveness. It notes that while the objectives and intentions of FRCs place considerable emphasis on strengthening family relationships and assisting families to stay together, the centres themselves have only a modest level of direct involvement with intact families. FRCs tend to have strong links with other community‐based family services, many of whom are more engaged with intact families; but it is difficult to gauge their effectiveness in this area. Most FRCs' direct services are aimed at separating families and most of that work involves family dispute resolution (family mediation) and associated services such as screening and assessment and the provision of relevant information. A substantial majority of clients who attend FDR at an FRC reach agreement about their parenting arrangements either at FDR or subsequent to attending FDR. These agreements also tend to hold up in the medium term. A majority of parents believe that at FDR, the child(ren)'s needs were taken into account; the parenting agreement worked for the child(ren); and the parenting agreement worked for them. A substantial proportion of FRC clients come from families that have experienced family violence or other dysfunctional behaviours, and such behaviours reduce the chances of resolving parenting disputes. The paper concludes by suggesting that having been created mainly as a default alternative to legal interventions and court processes, it is likely that a major future strength of FRCs will lie in their emerging capacity to work constructively not only with other relationship services and networks, but with family lawyers and the courts.     

Using birthing kits to promote clean birth practices in Ethiopia

This article explores three NGO projects that assemble and distribute clean birthing kits in Ethiopia. It contrasts the government's health strategy that aims to increase skilled birth attendance, with local realities as most women in rural and remote settings give birth at home, often in unhygienic conditions, and without skilled assistance. Many health facilities are also unable to provide hygienic conditions for birthing women. The findings indicate that clean birth kits have assisted the NGOs to effectively promote clean delivery at home or in health facilities, and to encourage antenatal care, and early referral to emergency obstetric and new-born care.     

Effect of Extraction Procedure and Gas Chromatography Temperature Program on Discrimination of MDMA Exhibits

Analysis of impurities in seized MDMA tablets can be used to determine the synthesis method used and to identify links among exhibits. However, no standardized method exists to generate impurity profiles, limiting comparisons among different laboratories. This research investigated the effect of extraction procedure and gas chromatography temperature program on the resulting impurity profiles. Five exhibits were extracted using liquid–liquid extraction (LLE) and headspace solid‐phase microextraction (HS‐SPME), then analyzed using two different temperature programs. Profiles were statistically assessed using principal components analysis. While LLE was more reproducible, more compounds were extracted using HS‐SPME, thus providing more informative chemical profiles. The longer temperature program (53 min vs. 36 min) allowed greater discrimination of exhibits, due to improved precision as a result of an extended hold time (12 min). This research further highlights the need for standardized extraction and analysis procedures to allow comparison of chemical profiles generated in different laboratories.     

Detection of latent fingerprints by the use of silver nitrate

Silver nitrate has been an established agent for the detection of latent fingerprints for some 120 years, and it was one of the few reagents suitable for use on porous surfaces until ninhydrin was introduced in forensics. The method is based on the reaction of silver ions with chlorides in the fingerprints, which are visualized in brown, violet or black. The literature describes many variations of the procedure, but the information provided is often vague and imprecise. The purpose of this study was to show whether this method can also be used on modern types of paper and how it should be applied. The results of the tests showed that silver nitrate solutions do work also on modern papers, but that they cannot be recommended as a standard, because the appearance of the prints and the paper background can strongly change in the course of time. The findings also do not justify the use of methanol-containing silver nitrate solutions in contrast to the variations based on water. For reasons of occupational safety, methanol, which is classified as poisonous, should not be used. The silver nitrate method may be taken into consideration, however, e.g. after the application of ninhydin, if there are hints that the potential fingerprints are not too old, have not been affected by moisture and if there are clues that the perpetrator perspired strongly while causing the prints.     

Association of Ignitable Liquid Residues to Neat Ignitable Liquids in the Presence of Matrix Interferences Using Chemometric Procedures*,†

Abstract: In fire debris analysis, weathering of ignitable liquids and matrix interferences can make the identification of ignitable liquid residues (ILRs) difficult. An objective method was developed to associate ILRs with the corresponding neat liquid with discrimination from matrix interferences using principal components analysis (PCA) and Pearson product moment correlation (PPMC) coefficients. Six ignitable liquids (gasoline, diesel, ultra pure paraffin lamp oil, adhesive remover, torch fuel, paint thinner) were spiked onto carpet, which was burned, then extracted using passive headspace extraction, and analyzed by gas chromatography‐mass spectrometry. Both light and heavy burn conditions were investigated. In the PCA scores plot, ignitable liquids were discriminated based on alkane and aromatic content. All ILRs were successfully associated with the corresponding neat liquid using both PCA and PPMC coefficients, regardless of the extent of burning. The method developed in this research may make the association of ILRs with corresponding neat liquids more objective.     

Voting for the Radical Right in Swedish Municipalities: Social Marginality and Ethnic Competition?

Sweden is no longer a negative, exceptional case regarding the presence of radical right‐wing populist parties. The Sweden Democrats has continually grown stronger, and in 2010 they won seats in the Swedish parliament. However, their electoral support varies considerably across Sweden. This study analyses their electoral support in 290 Swedish municipalities in order to explain this variance. Support is found for the social marginality hypothesis: electoral support for the Sweden Democrats tends to be negatively correlated with the average level of education and with the Gross Regional Product per capita, and positively correlated with the unemployment rate. The ethnic competition hypothesis, that there is a positive correlation between the proportion of immigrants and electoral support of the Sweden Democrats, is also supported.
