Construct validity,reliability and predictive validity of the dynamic risk assessment and management system (DRAMS) in offenders with intellectual disability

Background. There have been a number of developments in the assessment of dynamic risk in the criminological literature. The dynamic risk assessment and management system (DRAMS) has been developed to facilitate the measurement of dynamic factors of risk for offenders with intellectual disability. Method. The study was designed to assess the construct validity, reliability and predictive utility of the DRAMS in 23 male forensic patients in a high secure setting. Predictions were made against independently collected incident data. Concurrent validity was assessed against the Ward Anger Rating Scale (WARS). Results. A reformulation of the individual section variables according to convergent and discriminant correlational analysis revealed Cronbach's alpha levels of >.8 for all sections apart from mood (alpha .750) and items retained to facilitate clinical information (alpha ?.017). Two hundred pairs of WARS and DRAMS assessments revealed orderly sectional correlations. The sections of mood, antisocial behaviour, and intolerance/agreeableness predicted incidents with a medium effect size as did total DRAMS score. There were highly significant differences between assessments taken 1 or 2 days prior to an incident and control assessments conducted at least 7 days from an incident. Conclusions. The reformulated DRAMS has good construct and concurrent validity. It appears to be a reliable assessment tool and informs on risk levels relating to stable and acute proximal factors. It appears as an important addition to the utility of risk assessments for this population.     

The Forces of Law: Duty,Coercion, and Power

This paper addresses the relationship between law and coercive force. It defends, against Frederick Schauer's contrary claims, the following propositions: (a) The force of law consists in three things, not one: the imposition of duties, the use of coercion, and the exercise of social power. These are different and distinct. (b) Even if coercion is not part of the concept of law, coercion is connected to law many important ways, and these are amply recognized in contemporary analytic jurisprudence. (c) We cannot determine how important coercion is to the efficacy of law until we know what counts as coercive force. The question of what counts as coercion is not a matter for generalization or stipulation. It requires an explanation of the concept of coercion.     

Development and preliminary validation of The Multidimensional Sexual Coercion Questionnaire (MSCQ)

Abstract

The goal of this study is to present the development and validation of a sexual coercion assessment instrument for college students, the Multidimensional Sexual Coercion Questionnaire (MSCQ). An exploratory factor analysis for ordinal Likert data, followed by a confirmatory factor analysis in 762 college students, revealed seven factors. These pertained to commonly noted tactics such as pressure to have sex, exploitation, relational manipulation as well as less commonly measured tactics of humiliation and two clusters of tactics pertaining to forced compliance based on past coercion. Although several other measures exist, this measure was designed specifically for college students and therefore includes a wider array of tactics than generally considered. The measure also makes an attempt to include more nuanced and difficult-to-measure coercion strategies. The MSCQ is likely to be of interest to researchers and clinicians who wish to consider a more nuanced analysis of sexual coercion dynamics among college student, young adult and general populations.     

Agency,Coercion, and Global Justice: A Reply to My Critics

Mathias Risse, Andrea Sangiovanni, and Kok-Chor Tan have offered some subtle and powerful criticisms of the ideas given in my Justice and Foreign Policy. Three themes in particular recur in their critiques. The first is that the arguments I make in that book rest upon unjustified, arbitrary, or contradictory premises. The second is that the use of coercion in the analysis of distributive justice is a mistake. The third is that the global institutional set represents, contrary to my arguments, an independent first-order site of justice. I address these criticisms, and try to vindicate the methodology of Justice and Foreign Policy in the face of these objections.     

Distinguishing between forensic science and forensic pseudoscience: Testing of validity and reliability,and approaches to forensic voice comparison

In this paper it is argued that one should not attempt to directly assess whether a forensic analysis technique is scientifically acceptable. Rather one should first specify what one considers to be appropriate principles governing acceptable practice, then consider any particular approach in light of those principles. This paper focuses on one principle: the validity and reliability of an approach should be empirically tested under conditions reflecting those of the case under investigation using test data drawn from the relevant population. Versions of this principle have been key elements in several reports on forensic science, including forensic voice comparison, published over the last four-and-a-half decades. The aural–spectrographic approach to forensic voice comparison (also known as “voiceprint” or “voicegram” examination) and the currently widely practiced auditory–acoustic–phonetic approach are considered in light of this principle (these two approaches do not appear to be mutually exclusive). Approaches based on data, quantitative measurements, and statistical models are also considered in light of this principle.

Ambiguous Measures of Unknown Constructs: The MMPI-2 Fake Bad Scale (aka Symptom Validity Scale, FBS, FBS-r)

The Fake Bad Scale (FBS; Symptom Validity Scale) has fundamental psychometric flaws, interpretive problems, and potentially adverse societal consequences that are not appreciated by Ben-Porath et al. (Psychological Injury and Law 2(1), 62–85, 2009a, b). The FBS was constructed without due consideration to scientifically based guidelines for scale development (Clark and Watson, Psychological Assessment 7, 309–319, 1995; Jackson, Psychological Review 78, 229–248, 1971; Nunnally 1978; Holden and Troister, Canadian Psychology 50, 120–130, 2009). After almost two decades in existence, its face, content, and construct validity have not been established in the empirical literature. Oft-cited discriminant studies that appear to support the FBS are premature because of the scale’s unestablished psychometric foundation. In addition, these studies have significant methodological weaknesses that preclude definitive conclusions about what the scale actually measures. We review these weaknesses and recent legal cases that challenge the scale. We recommend that the FBS’s validity and fairness be addressed in an independent scientific review by the Buros Mental Measurement Test Evaluation System, a non-profit center specializing in the evaluation of commercially available tests.

Experimental results of fingerprint comparison validity and reliability: A review and critical analysis

Our purpose in this article is to determine whether the results of the published experiments on the accuracy and reliability of fingerprint comparison can be generalized to fingerprint laboratory casework, and/or to document the error rate of the Analysis–Comparison–Evaluation (ACE) method. We review the existing 13 published experiments on fingerprint comparison accuracy and reliability. These studies comprise the entire corpus of experimental research published on the accuracy of fingerprint comparisons since criminal courts first admitted forensic fingerprint evidence about 120 years ago. We start with the two studies by Ulery, Hicklin, Buscaglia and Roberts (2011, 2012), because they are recent, large, designed specifically to provide estimates of the accuracy and reliability of fingerprint comparisons, and to respond to the criticisms cited in the National Academy of Sciences Report (2009).Following the two Ulery et al. studies, we review and evaluate the other eleven experiments, considering problems that are unique to each. We then evaluate the 13 experiments for the problems common to all or most of them, especially with respect to the generalizability of their results to laboratory casework.Overall, we conclude that the experimental designs employed deviated from casework procedures in critical ways that preclude generalization of the results to casework. The experiments asked examiner-subjects to carry out their comparisons using different responses from those employed in casework; the experiments presented the comparisons in formats that differed from casework; the experiments enlisted highly trained examiners as experimental subjects rather than subjects drawn randomly from among all fingerprint examiners; the experiments did not use fingerprint test items known to be comparable in type and especially in difficulty to those encountered in casework; and the experiments did not require examiners to use the ACE method, nor was that method defined, controlled, or tested in these experiments.Until there is significant progress in defining and measuring the difficulty of fingerprint test materials, and until the steps to be followed in the ACE method are defined and measurable, we conclude that new experiments patterned on these existing experiments cannot inform the fingerprint profession or the courts about casework accuracy and errors.     

The reliability and validity of self,peer and staff reports of bullying and victimisation in correctional and care institutions

Abstract

Connell and Farrington (1997) carried out the first study of the reliability and validity of reports of bullying and victimisation in correctional institutions, using individual interviews. The present research describes the second study on this topic using questionnaire measures of self, peer and staff reports of bullying and victimisation in one Children's Home (N=16 residents, 15 peers, 6 staff, making up to 1440 comparisons) and one Correctional Home (N=19 residents, 18 peers, 6 staff, making up to 2052 comparisons) in Croatia. The present study improved on the Connell and Farrington study by examining the test–retest stability of the questionnaire and using relative improvement over chance coefficients in assessing inter-rater reliability. Unlike in the Connell and Farrington study, self-reports of bullying and victimisation were collected in small groups rather than in individual interviews. Generally, there was significant agreement between residents, peers and staff in identifying bullies and victims, and the test–retest stability of the questionnaire was high. In line with the findings of Connell and Farrington, it is concluded that self-reports provide the most reliable and valid data about bullying amongst institutionalised youth.     

The RECON typology of stalking: reliability and validity based upon a large sample of North American stalkers

A new typology of stalking, RECON (relationship and context-based), is proposed, based upon the prior relationship between the pursuer and the victim, and the context in which the stalking occurs. The static typology yields four groups: Intimate, Acquaintance, Public Figure, and Private Stranger. The typology was tested on a large (N = 1005) nonrandom sample of North American stalkers gathered from prosecutorial agencies, a large police department, an entertainment corporation security department, and the authors' files. Interrater reliability for group assignment was 0.95 (ICC). Discriminant validity (p < 0.01) was demonstrated on a variety of demographic, clinical, pursuit, threat, and violence characteristics among and between groups. Findings confirm and extend the work of other researchers, most notably the very high risk of threats and violence among prior sexually intimate stalkers, the very low risk of threats and violence among public figure (celebrity) stalkers, and the negative relationship between stalking violence and psychosis.     

The Influence of Prison Staff on Inmate Conditions: A Multilevel Approach to Staff and Inmate Surveys

The current study connects survey data of inmates and correctional staff in the Dutch prison system in order to describe and explain the impact of staff orientation and staff working conditions on perceived prison circumstances of inmates. Importation and deprivation theory are combined to test an integrated model to explain perceived prison conditions. By surveying staff (N = 1750) and inmates (N = 4673) independently within the same period of time and by afterwards pairing the results on the level of the housing unit (N = 173) using multilevel techniques, it is found that inmates′ perceptions of the prison conditions vary considerably between housing units. It is also found that staff’s perceptions of prison conditions show congruency with those of inmates. Another important finding is that in housing units where the orientation of staff towards inmates is relatively supportive, inmates perceive their circumstances as more positive. Conclusions and directions for further research are provided.     

The measurement of concern about victims: Empathy,victim advocacy and the Victim Concern Scale (VCS)

Purpose . In a series of studies, the authors developed the Victim Concern Scale (VCS) to assess levels of concern for diverse types of crime victims. The goal was to derive a psychometrically sound instrument and to assess victim concern in relation to other crime‐related attitudes and victim advocacy endorsements. Methods . Through several scale iterations, participant responses to the VCS were examined. Participants also completed measures of empathy and provided judgments about specific victim/crime scenarios. In addition, in two large samples (college [N = 276] and community [N = 478]), victim concern was compared with other attitudes, attributions and participant demographics. Results . Participants readily distinguished among different victims. Four factors emerged from the VCS. Raters endorsed the highest levels of concern for victims of violent crimes and the lowest level for ‘culpable’ victims. Women and older respondents showed higher levels of concern across all categories of victims. Both victim concern and emotional empathy influenced advocacy responses to victimization. Victim concern was unrelated to such traits and attitudes as authoritarianism, political ideology or punishment goals; moreover, a high level of concern for victims did not preclude endorsement of rehabilitative goals for offenders. Conclusions . The VCS appears to be a valid instrument for assessing levels of concern for victims. It differs meaningfully from measures of general empathy. The VCS could be used to assess differential attitudes across demographic groups or as a measure of change following exposure to educational or other persuasive intervention.     

The Community Policing Evaluation Survey: Reliability, validity, and structure

This paper describes the reliability, validity, and structure of a scale designed to evaluate community-policing programs. The Community Policing Evaluation Survey (CPES) is designed in such a way that local police agencies can implement it without the assistance of professional researchers. The scale consists of four subscales which measure (1) Quality of Contact with Police, (2) Perceptions of Crime and Disorder, (3) Personal Fear, and (4) Community Cohesion.
