司法精神病学鉴定后的处理情况调查

目的为了维护社会安全和依法保障精神病人的合法权益，需要正确处理精神病违法者。实际上，人们对司法精神病学鉴定后的处理情况知之甚少。因此，进行此项调查研究。方法采用邮寄调查问卷的方式对四川省52个县市的183例精神病违法者进行调查。结果在处置精神病违法者的机关中，公安局占73．08％，法院占26．72％。有责任能力组中有2．22％被无罪释放；无责任能力组中有2．10％被判刑；部分责任能力组中有13．95％被无罪释放。结论公安局是处理精神病违法者的主要机构。存在不适当处置情况，尤其对部分责任能力者的处理更复杂、更困难。     

Prevention of sexual violence by those who have been sexually violent

This article argues that indeterminate sentencing is the optimal means of preventing recidivism among sex offenders, both as an instrumental matter and jurisprudentially. Once a person is convicted of an offense, the duration and nature of sentence should be based on a back-end decision made by experts in recidivism reduction, within broad ranges set by the legislature. This position is defended against a number of objections, including claims that such a system relies on flawed risk assessments, ignores societal views of justice, denigrates offenders and victims, undermines deterrence and norm enforcement, depends too heavily on costly, uneven and demoralizing risk management schemes, and, as a result of one or more of these objections, is unconstitutional.     

Risk assessment with adolescent sex offenders

The paper describes an evaluation of a risk assessment tool's effectiveness in distinguishing adolescent sexual offenders who had committed further sexual offences from those who had not. The sample consisted of 50 male adolescent sexual offenders referred to a forensic outpatient service within a healthcare setting. The adolescents within the sample were designated recidivists versus non-recidivists using two methods: clinican's judgement and Home Office records for reconvictions. The risk assessment achieved a moderate to high level of sensitivity and specificity in distinguishing the recidivists from non-recidivists using clinician's judgement of recidivism as outcome. However, the tool was unable to distinguish recidivists from non-recidivists. The risk assessment tool described has potential in the identification and modification of contextual and clinical risk factors, in informing professionals’ decision-making and in developing and implementing a comprehensive risk management plan.     

Optimizing risk mitigation in management of sexual offenders: a structural model

Sexual violence is an insidious and pervasive problem that insinuates itself into all aspects of contemporary society. It can neither be mitigated nor adequately controlled through current socio-legal practices. A more promising approach must embrace four integrated elements: (1) public policy, (2) primary prevention, (3) statutory management, and (3) secondary intervention. In the present paper we tackle the 3rd and 4th elements by proposing an integrated model for reducing and managing sexual violence among known sex offenders. Relying on the highly effective Risk-Need-Responsivity (RNR) model as the core of our Sex Offender Risk Mitigation and Management Model (SORM³), we draw together evidence based practices from clinical interventions and risk assessment strategies. Developed by Andrews & Bonta (2006), RNR has a strong empirical track record of efficacy when applied to diverse samples of offenders, including sex offenders (Hanson, Bourgon, Helmus, & Hodgson, 2009). We offer a detailed structural model that seeks to provide a more seamless integration of risk assessment with management and discretionary decisions, including a primary focus on RNR-based post-release aftercare. We end with the mantra that sex offender treatment alone will never effectively mitigate sexual violence in society, since the problem is not confined to the handful of offenders who spend time in prison and are offered some limited exposure to treatment. Any truly effective model must go well beyond the management of those known to be violent and embrace a comprehensive and integrated approach that begins by recognizing the seeds of sexual violence sown by society. Such a public health paradigm places victims - not offenders - at the center, forcing society to come to address the full gamut of hazards that fuel sexual violence.     

Socially desirable responding and psychometric assessment of dynamic risk in sexual offenders against children

Does socially desirable responding (SDR) represent a threat to the validity of dynamic risk assessment in sex offenders’ self-reports? We studied a sample of men (N?=?218) who completed a psychometric assessment battery while enrolled at Kia Marama, a prison-based treatment program for sexual offenders against children. SDR, as measured by the Marlowe-Crowne scale, was elevated compared to non-offender samples, increased from pre- to post-treatment, and was negatively correlated with dynamic risk (rs?=??.30 to ?.40), consistent with previous research. Measures of dynamic risk factors derived from the psychometric battery were correlated with sexual recidivism, but correlations were little changed when variance associated with SDR was removed using a regression procedure [Mills, J. F., &; Kroner, D. G. (2006). Impression management and self-report among violent offenders. Journal of Interpersonal Violence, 21(2), 178–192.]. These results suggest that there is a substantial component of the variance in psychometric self-reports of sexual offenders that is associated with SDR (approximately 10%), but that it does not compromise the predictive or construct validity of dynamic risk measures derived from these reports.     

Social networks of sexual offenders

Abstract

Despite the extensive research attention directed toward criminal peer groups, there has been little attention to the peer groups of sexual offenders. Sexual offenders are often considered to be loners who offend in isolation, but cases of sex crimes involving peer support are not difficult to find, e.g., child sex rings, gang rapes. To examine the role of peers in sexual offending, sexual offenders and nonsexual offenders were asked whether they knew other people who have committed sexual crimes. In comparison to the nonoffender community comparison group, the sexual offenders reported considerably more association and identification with sexual offenders. The associations also tended to be offence specific, such that child molesters knew other child molesters and rapists knew other rapists. These findings have important implications for the assessment and treatment of sexual offenders.     

Violence risk profile of medium- and high-security NGRI offenders in Belgium

Under Belgian law, offenders not guilty by reason of insanity (NGRI) are committed by the courts to forensic mental health treatment. The use of violence risk assessment tools has become routine in these settings. However, there are no national statistics regarding violence risk assessment in the Belgian forensic population. A study was undertaken to collect risk assessment data (PCL-R, VRAG, HCR-20) on a large cohort of forensic patients committed to Medium Security units in the Flanders region and in High-Security units in the Walloon region. Flemish patients were expected to present a lower risk compared with their Walloon counterparts. Instead, data yielded by a structured risk assessment method demonstrate the opposite. Moreover, the majority of patients in Flemish facilities had committed violent offenses and were institutionalized for shorter periods whereas the majority of Walloon patients had committed sexual offenses and were institutionalized for markedly longer periods.     

A preliminary study on findings of psychopathy and affective disorders in adult sex offenders

The construct of psychopathy has often been considered mutually exclusive to the presence of genuine depressive or anxiety symptomotology. This article addresses the hypothesized reasons for this dichotomous relationship. In this study, 68 civilly committed adult male sex offenders were evaluated using a variety of psychological measures to determine if psychopathic individuals in this group would demonstrate clinically significant affective symptoms. Results indicate that the men in this sample endorsed high rates of psychopathy on the PCL-R, with 42% of these expressing concurrent symptoms of depression and 26% manifesting symptoms of an anxiety disorder. Relationships between affective symptoms and PCL-R factor scores and qualitative differences between these constructs in child molesters and rapists are also discussed.     

Predictive accuracy of static risk factors for Canadian Indigenous offenders compared to non-Indigenous offenders: implications for risk assessment scales

ABSTRACT

The over-representation of Indigenous offenders in Canadian prisons highlights the importance of research on the generalizability of potential static risk factors for this group. The current investigation examined whether 87 static indicators currently assessed in Canadian federal prisons were differentially present and related to outcomes (revocations, general recidivism, and violent recidivism) for Indigenous (n?=?1500) and non-Indigenous (n?=?6684) male federal offenders. The follow-up was eight months for revocations and five years for any/violent recidivism. Indigenous offenders scored significantly higher risk than non-Indigenous offenders on the majority of the indicators (particularly criminal history indicators). Generally, most criminal history indicators and some offence severity indicators predicted revocations, general, and violent recidivism for Indigenous offenders; however, several of the indicators had significantly lower accuracy for Indigenous offenders (particularly criminal history indicators). Overall, Indigenous offenders are a higher risk population and several static risk indicators do not perform as well for this group as for non-Indigenous offenders. Nonetheless, there were numerous static indicators that did predict outcomes for Indigenous offenders. The current findings suggest that it is possible to meaningfully assess static risk for recidivism among Indigenous offenders.     

Violent Sex Offenses: How are They Best Measured from Official Records?

In the United States, sexually violent predator (SVP) commitment statutes generally require assessment of an offender's risk of subsequent sexual violence. Current actuarial methods for predicting sexual reoffending were actually designed to predict something else—charges or convictions for offenses deemed sexual based on information obtained from police “rapsheets” alone. This study examined the referral and past offenses of 177 sex offenders. Results showed that police rapsheets (and data based on them) underestimated the number and severity of sexually motivated violent offenses for which sex offenders were actually apprehended. Rapsheet violent offenses seemed a more accurate index of the conduct addressed by SVP legislation than were rapsheet sex offenses. We suggest that, when evaluating sex offenders for SVP status, actuarial instruments designed to predict violent recidivism (as measured by rapsheet violent reoffenses) might be preferable to those designed to predict sexual recidivism (as measured by rapsheet sexual reoffenses).

Using wilderness therapy in treating adolescent sexual offenders

Abstract

This article describes a follow-up study of 14 adolescent sexual offenders who had attended a community treatment programme. A core component of their treatment included outdoor wilderness group therapy. Interviews were conducted with adolescents and parents and tapped several areas including social skills and peer relationships, victim empathy, cognitive distortions, safety plans and coping with high risk situations, sexual offending cycle, perceived level of risk, intimacy and sexuality. The study also examined the child protection service records of the It adolescents. Data from child protection service computer records showed that none of the adolescents had reoffended. Interviews with adolescents and families focusing particularly on the wilderness component of the programme showed positive changes.     

Measuring motivation to change in offenders

Abstract

Measuring motivation to change in offender populations is important both for selection into treatment programmes and for assessing progress in therapy. Two studies are reported in this paper, both looking at the psychometric properties of questionnaires designed to measure stage of change in therapy. The samples used were patients detained in special hospitals under the Mental Health Act (1983) classification of psychopathic disorder. The first study provides norms for this group on the stages of change in psychotherapy questionnaire, plus some additional information on its relationship with self-esteem and self-efficacy measures. The second study looked at a brief version of the stages of change questionnaire, concluding that its psychometric properties were such that further use was contra-indicated.     

A psychometric comparison of internet and non-internet sex offenders from a community treatment sample

Abstract

This paper compares psychometric test assessments of 39 men convicted of internet sex offences with 39 convicted of contact offences against a specific victim. Higher rates of socially desirable responding were identified in the internet group, as well as higher rates of emotional loneliness and under assertiveness, although the latter two findings were not statistically significant. This group also achieved lower scores measuring external locus of control, which might reflect their generally higher levels of education and employment (identified from research carried out in tandem with this work). The internet group achieved lower scores on sexualized attitudes towards children, emotional congruence with children and empathy distortions with regard to victims of child abuse. Hence, although they exhibited the kinds of general personality problems exhibited by other sex offenders, they did not support attitudes that explicitly endorse or condone the sexual abuse of children. This paper presents some hypotheses about these results and identifies further research necessary to develop understanding about this new kind of sexually abusive behaviour.     

Empathy deficits of sexual offenders: A conceptual model

Most treatment programmes for sexual offenders include some form of victim empathy training. Although the concept of empathy has acquired diverse meanings, those interested in sexual offenders' empathy deficits are primarily concerned about the offenders' lack of compassion or sympathy for their victims. A model of empathy is presented in which uncompassionate responses are the product of three initial conditions: a) an adversarial or indifferent relationship; b) perspective-taking deficits; and c) inappropriate methods for coping with the perceived distress of others. The model suggests that empathy training should target specific deficits, and that misdirected interventions would be expected to have no effects, or even detrimental effects, on the offenders' ability to generate sympathetic, compassionate responses to victims.     

Predictors of length of stay in forensic psychiatry: The influence of perceived risk of violence

This study describes the prevalence of adverse events and length of stay in forensic psychiatric patients with and without a restriction order. Detailed clinical and administrative information from medical records and written court decisions was gathered retrospectively from admission until discharge for a Swedish population-based, consecutive cohort of forensic psychiatric patients (n = 125). The median length of stay for the whole cohort was 951 days, but patients with a restriction order stayed in hospital almost five times as long as patients without. Restriction orders were related to convictions for violent crime, but not for any other differences in demographic or clinical variables. The majority of the patients (60%) were involved in adverse events (violence, threats, substance abuse, or absconding) at some time during their treatment. Patients with restriction orders were overrepresented in violent and threat events. Previous contact with child and adolescence psychiatric services, current violent index crime, psychotic disorders, a history of substance, and absconding during treatment predicted longer length of stay. Being a parent, high current Global Assessment of Functioning scores, and mood disorders were all significantly related to earlier discharge. In a stepwise Cox regression analysis current violent index crime and absconding remained risk factors for a longer hospital stay, while a diagnosis of mood disorder was significantly related to a shorter length of stay.     

Topographies of forensic practice in Imperial Germany

This article examines the topography and “cultural machinery” of forensic jurisdictions in Imperial Germany. It locates the sites at which boundary disputes between psychiatric and legal professionals arose and explores the strategies and practices that governed the division of expert labor between them. It argues that the over-determined paradigms of ‘medicalization’ and ‘biologization’ have lost much of their explanatory force and that historians need to refocus their attention on the institutional and administrative configuration of forensic practices in Germany. After first sketching the statutory context of those practices, the article explores how contentious jurisdictional negotiations pitted various administrative, financial, public security, and scientific interests against one another. The article also assesses the contested status of psychiatric expertise in the courtroom, as well as post-graduate forensic psychiatric training courses and joint professional organizations, which drew the two professional communities closer together and mediated their jurisdictional disputes.     

The highs and lows of working with sexual offenders: A New Zealand perspective

Abstract

The positive effects on clinicians responsible for the treatment of sexual offenders are little understood. The few available studies have focused upon the negative sequelae of this work. The current study of clinicians working therapeutically with sexual offenders at a community-based organization aimed for a more balanced picture of the effects of sex offender treatment provision. Using qualitative methods, both negative and positive aspects of this work emerged within three main themes: taking an optimistic perspective, working for community outcomes and supportive agency culture. Although the study revealed many challenges for therapists, these were found to be counterbalanced against rewards, affording a high degree of personal and professional fulfilment from working within this field.     

Sociodemographic and diagnostic characteristics of homicidal and nonhomicidal sexual offenders

The aims of this study were to compare the prevalence of psychiatric disorders and "psychopathy" in homicidal and nonhomicidal sexual offenders and to investigate the specificity of previous studies on psychiatric morbidity of a sample of sexual murderers. Information from court reports of 166 homicidal and 56 nonhomicidal sex offenders was evaluated using standardized instruments (SCID-II, PCL-R) and classification systems (DSM-IV). Sexual murderers were diagnosed more often with a personality disorder (80.1% vs. 50%; p < 0.001), especially schizoid personality disorder (16.3% vs. 5.4%; p < 0.05), as well as with sexual sadism (36.7% vs. 8.9%; p < 0.001) and sexual dysfunctions (21.7% vs. 7.1%; p < 0.05). Additionally, they had more often used alcohol during the offense (63.2% vs. 41%; p < 0.05). The results indicate that sexual murderers have more and a greater variety of psychiatric disorders when compared to nonhomicidal sex offenders.
