Co-witnesses talk: A survey of eyewitness discussion

Abstract

The objective of this study was to obtain a quantitative measure of the discussion behaviour of real eyewitnesses. Undergraduate psychology students were given a questionnaire to determine if they had witnessed a serious event. Results from the questionnaire showed that the majority of respondents had witnessed a serious event at some point in their lives, and the majority of witnesses were not alone when they observed the event. Respondents who had experienced a serious event for which there was more than one witness present were invited to fill out a follow-up questionnaire. The follow-up study showed that when there is a co-witness present, most people (86%) report discussing the event with the co-witness. This is potentially problematic if the witnesses are contaminating one another's memories of the event. The results are discussed in terms of psychological research and policy implications.     

Can a witness report hearsay evidence unintentionally? The effects of discussion on eyewitness memory

Abstract

When eyewitnesses are exposed to misinformation about an event from a co-witness, they often incorporate this misinformation in their recall of the event. The current research aimed to investigate whether this memory conformity phenomenon is due to change in the witness's memory for the event, or to social pressures to conform to the co-witness's account. Participants were shown a crime video and then asked to discuss the video in groups, with some receiving misinformation about the event from their discussion partners. After a one-week delay some participants were warned about possible misinformation before all participants provided their own account of the event. In Study 1, participants made remember/know judgments about the items recalled, and in Study 2 they indicated the source of their memories. Co-witness information was incorporated into participants’ testimonies, and this effect was not reduced by warnings or source monitoring instructions, suggesting memory change may have occurred. However, there was some indication that remember/know judgments may help distinguish between ‘real’ memories and co-witness information.     

Outcome measurement in forensic mental health research: an evaluation

Abstract

Measuring change resulting from healthcare interventions is critical to evaluating their usefulness. The choice of outcome measure is an important part of such evaluations and is driven by assumptions about what is likely to change and how best to capture this. Despite its importance, forensic mental health has paid little attention to determining which are the best measures of outcome. This study used a panel of relevant professionals to (i) assess the relative importance of different areas of potential outcome measurement and (ii) evaluate specific instruments used currently as outcome measures in forensic mental health research. Although a wide range of potential outcomes were endorsed as appropriate, few corresponding instruments have been used consistently. Only three psychiatric instruments deemed by our panel as feasible, relevant and psychometrically adequate have been used in five or more studies (the Beck Depression Inventory; the Brief Psychiatric Rating Scale, and the Symptom Checklist-90–Revised). Significant measurement gaps were noted in areas such as social and emotional functioning. Although instruments exist that could capture most areas, none were sufficiently developed for routine use as outcomes. Further research to develop robust, sensitive and diverse outcome measures is needed. This is an essential precursor to extending the evidence base for forensic mental health interventions.     

Editorial

ABSTRACT

The current paper examined the association between childhood sexual victimization (CSV) and constructs thought to be relevant for sexual offending in secondary analyses of three samples of adult males who committed sexual offences against children (N?=?16, 28, and 20). Compared to participants who reported no CSV, those who reported CSV exhibited slightly to moderately more cognitive distortions and moderately to largely less negative evaluations of sexual offending against children; slightly to moderately higher self-esteem, positive evaluation of people who commit sexual offences, and identification with people who commit sexual offences against children; and much more emotional congruence with children. Our findings suggest that CSV may be associated with variables presumed to play a role in sexual offending against children. However, given the small sample sizes and other limitations of our studies, our evidence does not permit conclusions regarding causal relationships and any novel findings require replication.     

Measuring grievance thinking in sexual offenders: The revised Dissipation–Rumination Scale

Abstract

Rumination is an important part of “grievance thinking”, which has been linked to recidivism in sexual offenders. Grievance thinking is a dynamic risk factor that can be targeted in treatment, and is characterized by a perception of being wronged accompanied by angry, hostile rumination about revenge, and has similarities to the “dangerous world” implicit theory . A revised version of the Dissipation–Rumination Scale is used currently to measure grievance thinking in sexual offenders incarcerated in England and Wales. The study aimed to establish whether this revised measure is valid to use with this population. The scale demonstrated adequate reliability and good convergent validity. However, analyses revealed problems with both construct and predictive validity. Further, it is suggested that the scale may not be sufficient to measure the whole of the “grievance thinking” concept. The results do not provide overwhelming support for the use of this tool with sexual offenders; further research is required before firm conclusions can be drawn regarding the scale's utility. Directions for future research are discussed.     

An analysis of the relationship between being deaf and sexual offending

Abstract

Research demonstrates that deaf offenders are over-represented within the criminal justice system. In addition, those deaf offenders who are incarcerated within prison estates or psychiatric units are predominantly incarcerated for sexual offences. This paper will evaluate the existing literature surrounding the reasons behind this bias. In particular, this review will examine the characteristics of deaf offenders in relation to their personalities, language and brain development and abilities to communicate. This paper will consider proposed associations between mental illness and childhood sexual abuse amongst deaf individuals and later sexual offending. This paper attempts to evidence differences between deaf and hearing offenders in order to explain why more deaf offenders commit sexual crimes than hearing offenders. This paper will conclude that the research is scarce and inconclusive and that current assessments and treatment are potentially inadequate due to the profound difficulties associated with accurately understanding and communicating with the deaf offender.     

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.     

The development and initial testing of the AIM2 framework to assess risk and strengths in young people who sexually offend

Abstract

This paper describes the AIM2 assessment framework and the process of its development and initial testing. AIM2 is used to assess areas of concerns and strengths of young people. Some preliminary analysis is described, including the correlation of assessment items, their ability to discriminate between cases, their inter-rater reliability and a small-scale recidivist study. These analyses were used to develop AIM2. Results from the recidivist study identified a particular set of concern and strength factors associated with recidivism in the sample. We conclude that the inclusion of strengths-related items are important to consider as protective factors when assessing the risk of further sexually abusive behaviours. Limitations and future directions of AIM2 are also discussed.
