The relationship of suggestibility and compliance with self-deception and other-deception

The aim of the study was to assess the relationship of interrogative suggestibility and compliance with other-deception and self-deception. The Gudjonsson Suggestibility Scale (GSS 1), the Gudjonsson Compliance Scale (GCS), the Eysenck Personality Questionnaire (EPQ), and the Other and Self-Deception questionnaires (ODQ and SDQ) were administered to 237 Icelandic prison inmates. Other and Self-Deception scores did not correlate significantly with suggestibility and compliance, whereas significant correlations were found between the deception scores and EPQ Psychoticism, Neuroticism and Lie scores. The EPQ Lie score explained about one-third of the variance in the ODQ score, suggesting a considerable overlap between the two impression management measures. The most important practical implication of the findings is that self-favouring bias does not appear to significantly influence suggestibility and compliance scores.     

Violence ratings of female patients in broadmoor hospital

Abstract

A study is described which characterised the female population of Broadmoor Special Hospital on a scale (Robertson et al., 1987) which rates violence associated with the index offence and previous episodes of violence both in terms of prosecuted violence and unprosecuted incidents. This scale has been applied recently to the male population of Broadmoor (Wong et al., 1993). The findings here confirm the notion that the female population of a Special Hospital are less violent than the males in terms of rating of violence associated with the index offence and in previous convictions for violent offending. The females contain a larger proportion of patients convicted of the offence of Arson (index offence) and patients transferred from other hospitals because of being unmanageable in these settings (under Section 3 of the Mental Health Act). Extreme ratings of violence amongst the females is associated with a diagnosis of personality disorder rather than schizophrenia or psychosis.     

Determining security level in forensic psychiatry: a tug of war between the DUNDRUM toolkit and the HoNOS-Secure

ABSTRACT

Criteria to determine in which level of security forensic patients should receive treatment are currently non-existent in Belgium. Research regarding the assessment of security level is minimal, and limited instruments are available. This study investigated the instruments that measure the need for security level: DUNDRUM-1 and the HoNOS-Secure. The psychometric properties of the DUNDRUM-1, DUNDRUM-2 and the HoNOS-Secure were investigated.

A random selection was made of 100 male forensic patients in prison. The DUNDRUM-1, DUNDRUM-2 and the HoNOS-Secure were scored retrospectively. A subsample of the files was rated by four researchers (n?=?38). Comparisons were made with the security level as decided by the court.

The DUNDRUM-1 achieved excellent inter-rater reliability, and the HoNOS-Secure and DUNDRUM-2 got a moderate score. The internal consistency was highest for DUNDRUM-1 followed by the HoNOS-Secure and was low for the DUNDRUM-2. Both the DUNDRUM-1 and the HoNOS-Secure predicted allocations by the court to high security.

The DUNDRUM-1 outperforms the HoNOS-Secure on psychometric properties and provides clear instructions with regard to the assessment of the security level. Training seems to be important for scoring the DUNDRUM-1. The current study provided more evidence for the applicability of the DUNDRUM-1 in Belgian settings with regard to determining the need for security.     

Ethnic differences in the relationship between psychopathy and (re)offending in a sample of juvenile delinquents

The present study focused on the relationship between psychopathy and delinquency in a multiethnic sample of juvenile offenders (N=207, n=105 native Dutch, and n=102 immigrants) referred to a treatment program. Aims were (1) to examine the cross-ethnic equivalence of the Antisocial Process Screening Device (APSD); (2) to compare the mean levels of psychopathic traits in native Dutch and immigrant juvenile delinquents and (3) the strength of the associations between psychopathic traits and delinquency in both the native Dutch and immigrant samples. Measurement invariance was established for APSD factors assessing callous-unemotional (CU) traits and impulsivity. However, there were ethnic differences in the factor structure of narcissism. No differences were found between ethnic groups in mean levels of CU traits and impulsivity. Finally, the association between impulsivity and self-reported delinquency was stronger for native Dutch than for immigrant juveniles. Further research is needed in order to make the treatment of juvenile delinquents with psychopathic traits in ethnic minority groups more effective according to the specific needs of these juveniles.     

Social Disadvantage and Students' Perceived Injustice in Socially Integrated Schools in Israel

In this study we explored objective and attributed explanations of perceived injustice (PI) with respect to instrumental and relational rewards among junior high school students. Despite the socially heterogeneous school and classroom setting, PI found was relatively modest and differentiated by domain. It was more effectively accounted for by cognitive ability than by socioeconomic status, while the effect of ethnic extraction was very small. PI was attributed much less to social background than to teacher and individual factors with regards to instrumental rewards, and to teacher and peer behavior concerning relational rewards. To explain these findings we have suggested the egalitarian climate of the school and its success in bringing students to comply with the meritocratic norm, the disadvantaged students' rational consideration of the positive contribution of the integrated school to their life chances, and the diminishing ethnic identification among the younger strata of the Israeli society.     

Validity in judgments of high‐ and low‐accurate witnesses of own and other ethnic groups

Purpose. Research has shown that people often have difficulties estimating eyewitness accuracy correctly. In most previous studies examining validity in credibility judgments, participants have assessed the accuracy of witnesses who have been homogeneous in their memory performance. This study investigated validity in judgments of witnesses who varied widely in memory. A further purpose was to examine whether judgmental validity was moderated by the witnesses' ethnic in‐group/out‐group status. Methods. Participants (N = 120) rated the reliability of videotaped testimonies of high‐ and low‐accurate in‐group (Swedish, N = 4) and out‐group (immigrants, N = 4) witnesses who were genuinely trying to recall a criminal event. Results. Participants assigned more reliability to high‐ than to low‐accurate in‐group witnesses, while out‐group witnesses received low reliability ratings regardless of their actual memory performance. Path analyses demonstrated that the subjective confidence of in‐group, but not of out‐group, witnesses predicted participants' accuracy judgments. Conclusions. The results indicate that the validity in judgments of in‐group witnesses can be better than has previously been implied. Investigators may have difficulty distinguishing high‐ and low‐accurate witnesses from other ethnic groups, and they may also systematically underestimate the reliability of ethnic out‐group witnesses. Implications for legal practices are discussed.     

Implementing violence and incident reporting measures on a forensic mental health unit

The assessment of risk and prediction of violence in mental health units can play a large role in creating a safer environment for both the staff and the patients. Nurses in forensic units are in a unique position in regards to assessment of violence as they spend a great deal of time with the patients. Nurses on a forensic mental health unit scored the Brøset Violence Checklist (BVC) twice daily for 12 weeks for all patients either resident on or admitted to the unit (N?=?46). The Staff Observation Aggression Scale-Revised (SOAS-R) was used to report any adverse incidents (N?=?51). Data were examined at the both the item and scale level. Main results showed the area under the curve values of the BVC score, slide rule, and the sum of BVC and slide rule score in turn demonstrated strong predictive accuracy for inpatient aggression (0.68–0.73). Through logistic regression analyses the BVC uniquely predicted inpatient aggression but adding the slide rule did not improve prediction. Predictive accuracy was found across three diagnostic groups – dementia, psychosis and substance use disorders. These results provide further support on the predictive accuracy of the BVC for short-term violence in forensic mental health settings.     

An Improved Equation for TBS and ADD: Establishing a Reliable Postmortem Interval Framework for Casework and Experimental Studies

Megyesi et al.'s (J Forensic Sci, 2005, 50, 618) paper was important to forensic anthropology as it introduced a quantitative framework for estimating time since death in human cadavers, based upon physical appearance by way of scoring on a novel scale. However, errors concerning rounding, temperature scale, and incorrect use of a statistical regression model render their predictive formula unusable. Based upon only their more reliable data, a more appropriate regression model to predict accumulated degree days (ADD) from total body score (TBS) is presented. The new model is also a superior fit (r² = 0.91) and produces markedly narrower confidence intervals than the original, which also allowed impossible, negative ADD values. Explanations of the shortcomings in the original analysis and calculations are presented, which it is hoped will help forensic scientists avoid making similar mistakes.     

Appeals against detention in conditions of excessive security: outcomes and decision-making

The Mental Health (Care and Treatment) Scotland Act 2003 introduced the right for patients to appeal against detention in conditions of excessive security initially to those in high security. Aim: to further investigate appeal outcomes and to examine Tribunal decision-making. Results: responsible medical officer support, being on the transfer list and not having a diagnosis of learning disability increased the chances of a successful appeal. Qualitative analysis of the Tribunal’s decision-making produced 5 themes and 17 subthemes. These were used to develop a ‘checklist’ framework to improve understanding of relevant appeal factors. Conclusions: Neither appeal outcomes nor patient characteristics have changed over time. The checklist may be useful as a training tool and clinical guide. This study is timely given that the Mental Health (Scotland) Act 2015 extended the right of appeal against excessive security to patients detained within medium secure units from November 2015.     

Comparison of MMPI psychopathic deviate scores of battered and nonbattered women

Despite the voluminous research using the Minnesota Multiphasic Personality Inventory, little research has been done evaluating the MMPI for assessing personality profiles and psychopathology in victims of domestic violence. The current study focused on the Psychopathic Deviate scale (scale 4), and the Harris and Lingoes subscales measuring specific aspects of this concept. The objective was to evaluate whether a clinical population of battered women differed from a nonbattered group drawn from a similar clinical setting. The battered group scored higher on the full scale (p .001), the Authority Problems scale (p .001), the Social Alienation scale, (p .01), and the Social Imperturbability scale (p .05). There was no difference on Self-Alienation. The score on Family Discord (Pd1) was the most elevated for the battered group, falling just below moderately elevated. Within the battered group, the score on Family Discord (M =69.11) was significantly more highly elevated than the score on Self-Alienation (M =60.4) (the next most highly elevated score). These findings suggest that there is an association between elevated scale 4 scores and victimization by domestic violence. However, it is essential that clinicians carefully evaluate such scores in the context of each individual situation before attributing causation.     

Reactions to Crime as a Hierarchy Regulating Strategy: The Moderating Role of Social Dominance Orientation

Across two studies, we demonstrated that support for group-based hierarchies differentially affects evaluation of ingroup and outgroup criminal offenders and that this effect generalizes to overall evaluations of their respective groups. Drawing on social dominance theory, our results show that differential judgments of national ingroup and immigrant outgroup offenders reflect hierarchy regulating strategies. Study 1 (N = 94) revealed that egalitarians (low on SDO) were more lenient toward outgroup offenders and their ethnic group (Arab immigrants) when compared to ingroup offenders and their national group (Swiss citizens). The opposite was true for social dominators (high on SDO). Study 2 (N = 88) replicated the results of Study 1 and further demonstrated that the socio-economic status of the perpetrator did not affect perpetrator group evaluations suggesting that the arbitrary sets of ethnicity or nationality, not education level and employment status, were the important cues for hierarchy-regulating judgments of criminal offenders.     

The utility of the Strengths and Difficulties Questionnaire as a screening measure among children and adolescents who light fires

Background: This pilot study examined the utility of the Strengths and Difficulties Questionnaire (SDQ) as a standardised screening tool for behavioural and psychosocial problems by fire service-based programmes to identify at-risk young firesetters who are in need of further comprehensive multiagency intervention. Method: SDQ scores were obtained from 57 children and adolescents, aged 6–17 years, who were referred to the Fire Awareness and Intervention Programme in New Zealand for firesetting behaviour. Scores from firesetters aged 13–17 years were compared to those of typically developing New Zealand secondary school students. Results: Overall, young firesetters were at a high risk of clinically significant conduct and hyperactivity/inattention difficulties, and at low risk of clinically significant emotional problems. Cronbach’s alphas for most SDQ subscales were acceptable. Conclusions: We recommend that the SDQ be considered by fire service-operated interventions for use as an additional assessment tool for the young firesetting population.

Key Practitioner Messages ? Due to its financial and emotional cost, deliberate firesetting by children and adolescents is a significant concern for communities.

? There appears to be significant comorbidity between firesetting and serious antisocial behaviour, and many young firesetters engage in ongoing general offending behaviour.

? Intervention for child and adolescent firesetters is predominantly provided by fire services and typically involves fire safety education.

? Given the co-morbid behavioural and psychosocial problems present among young firesetters, there is a need for fire service education programmes to use a standardised assessment tool that screens for wider behavioural and psychosocial difficulties to assist in the identification and referral of high-risk young people to appropriate services for further intervention.

? The SDQ, a free, short and well-validated measure, could be adopted by fire service-operated education programmes to help detect and inform the referral of young firesetters who need more comprehensive multiagency intervention.

     

A Failure to Find Empirical Support for the Homology Assumption in Criminal Profiling

A fundamental assumption in criminal profiling is that criminals who exhibit similar crime scene actions have similar background characteristics. We tested this so-called homology assumption by first classifying, with pre-existing typologies, a sample of arsons (N = 87) and robberies (N = 177) into different crime types and then comparing the background characteristics of criminals who committed the various crime types. Results showed that using pre-existing typologies to classify the crimes into mutually exclusive types was not easily accomplished. Notwithstanding classification difficulties, the homology assumption was violated in 56% of the comparisons of background characteristics between the different arson types and in 67% of the comparisons of background characteristics between the different robbery types. Overall, 73% of the effect sizes for the associations between crime type and background characteristics were low to moderate (V < .3; d < .2). The implications of these findings for profiling practices are discussed.

Inpatient aggression by mentally ill offenders: a retrospective case-control study

A retrospective case-control study was conducted examining relationships between patients’ socio-demographic, clinical and admission characteristics and inpatient aggression. Patients aged 18–64?years with a recent offence episode, who were admitted to a regional acute mental health unit, were included as cases (N?=?82), while controls comprised the next available admission, matched for age and gender (N?=?82). The prototypical patient was a young, single male, with a diagnosis of schizophrenia, a history of substance use and previous psychiatric admissions. The majority of cases had a history of aggression and recent offences against public order. They also revealed a higher likelihood of involvement in ‘less serious’ aggressive incidents (e.g. verbal threats or demands) during the index admission. Clinically, knowledge of each patient’s recent offence history, arrival mode and observed characteristics on admission (including any verbal aggression) may be important in the management of subsequent inpatient aggression.     

Attachment and social bonding in maximum and minimum security prison inmates

Attitudes towards social attachment and bonding were evaluated in groups of maximum (N = 48) and minimum (N=46) security prison inmates and compared with the attitudes of a group of 49 noncriminal college students. Three primary styles of attachment were considered: avoidant, ambivalent/anxious, and secure. It was predicted that the maximum security condition, a group hypothesized to contain a large number of lifestyle criminals, would evidence more of an avoidant style of attachment compared to minimum security inmates or a group of coliege student controls. Consistent with this hypothesis, the maximum security inmates exhibited greater avoidance in their attitudes towards relationships than subjects in the other two conditions. The implications of these results are discussed.     

Field validity of the HCR-20 in forensic medium security units in Flanders

Structured risk assessment has become a part of routine practice in forensic settings. However, little attention has been paid to the clinical applicability of existing tools. The present research focused on the performance of the Historical Clinical Risk Management-20 (HCR-20) – one of the most commonly used tools for structured professional judgment – in the daily practice of three medium security units in Flanders. Areas under the curve for the prediction of violent recidivism during (N?=?168) and after (N?=?105) medium security treatment were non-significant. In addition, analyses showed that the HCR-20 was mainly of interest in identifying low-risk individuals. Further research measuring different aspects of predictive validity in applied settings is recommended.     

Attachment and social bonding in maximum and minimum security prison inmates

Attitudes towards social attachment and bonding were evaluated in groups of maximum (N=48) and bonding were evaluated in groups of maximum (N=46) security prison inmates and compared with the attitudes of a group of 49 noncriminal college students. Three primary styles of attachment were considered: avoidant, ambivalent/anxious, and secure. It was predicted that the maximum security condition, a group hypothesized to contain a large number of lifestyle criminals, would evidence more of an avoidant style of attachment compared to minimum security inmates or a group of college student controls. Consistent with this hypothesis, the maximum security inmates exhibited greater avoidance in their attitudes towards relationships than subjects in the other two conditions. The implications of these results are discussed.     

Comparison of Protocols for Measuring and Calculating Postmortem Submersion Intervals for Human Analogs in Fresh Water

Protocols for determining postmortem submersion interval (PMSI) have long been problematic for forensic investigators due to the wide variety of factors affecting the rate of decomposition of submerged carrion. Likewise, it has been equally problematic for researchers to develop standardized experimental protocols to monitor underwater decomposition without artificially affecting the decomposition rate. This study compares two experimental protocols: (i) underwater in situ evaluation with photographic documentation utilizing the Heaton et al. total aquatic decomposition (TAD) score and (ii) weighing the carrion before and after submersion. Complete forensic necropsies were performed as a control. Perinatal piglets were used as human analogs. The results of this study indicate that in order to objectively measure decomposition over time, the human analog should be examined at depth using the TAD scoring system rather than utilizing a carrion weight evaluation. The acquired TAD score can be used to calculate an approximate PMSI.     

Discrimination Towards Ethnic Minorities: How Does it Relate to Majority Group Members’ Outgroup Attitudes and Support for Multiculturalism

We examined how ethnic discrimination targeting ethnic minority group members would affect majority group members’ attitudes and multiculturalism towards ethnic minority groups in the context of Turkish–Kurdish interethnic conflict. Study 1 (N = 356) demonstrated that the extent to which majorities (Turkish) believed there was ethnic discrimination towards minorities (Kurdish) in the Turkish society was associated with positive outgroup attitudes and support for multiculturalism through decreased levels of perceived threat from the outgroup. Study 2 (N = 82) showed that Turkish participants who read bogus news reports about the prevalence of ethnic discrimination towards the Kurdish were more positive towards this ethnic group (higher levels of support for multiculturalism, culture maintenance, and intergroup contact) compared to participants in the neutral condition. Furthermore, participants who were presented with lower levels of discrimination (few companies have been discriminatory against the Kurdish) were more positive towards Kurdish people than participants who were presented with higher levels of discrimination (most companies have been discriminatory against the Kurdish). Regardless of the intensity of discrimination, information about the prevalence of ethnic discrimination improved majority members’ attitudes towards ethnic minority groups. Practical and theoretical implications of the studies were discussed.     

Developing a new scoring method to evaluate human decomposition in a humid,continental (Dfb) climate in Quebec

The published literature shows a lack of methods to evaluate the patterns and extent of decomposition of human remains and to estimate the post-mortem interval (PMI) in humid, continental (Dfb) climates such as Quebec. The aim of this study was to address this gap in the current knowledge base by providing the first observations from human corpses studied under controlled conditions in Quebec. A 12-month study was conducted at the site for Research in Experimental and Social Thanatology; the first human taphonomy facility in Canada. Six human donors with known time of death were deposited across spring (n = 1), summer (n = 3), and autumn (n = 2) 2021. The lack of suitability of the total body score method to evaluate the extent of decomposition at the facility prompted the development of a new scoring system based on the macromorphoscopic changes observed. The scoring system was applied to the donors to evaluate decomposition throughout seasons. All donors followed comparable decomposition trajectories, regardless of the season of deposition. Eighty-five percent of taphonomic patterns appeared in the first 25 experimental days or 5000 Kelvin accumulated degree days (350 ADD). Extensive desiccation of tissues was observed at a median of 21 experimental days across donors, resulting in a plateau within decomposition with no extensive skeletonization. To the authors' knowledge, this is the first published report of experimentally observed desiccation in such a form in a Dfb climate. This study provides new data on the types of decomposition patterns to expect in forensic investigations in southern Quebec and comparable climates.
