Values in forensic and correctional psychology

Although the practice of forensic and correctional psychology has been understood in relation to certain sets of values that have been articulated in codes of ethical practice or organisational mission statements, there has been little consideration of how the values of offenders can inform the rehabilitative process. In this paper the criminogenic nature of values is discussed and how these might be addressed in an intervention. It is concluded that an exploration of values is not only a necessary condition for successful rehabilitation, but also essential if ethical problems in working with offenders are to be avoided.

Writing reports for court : a practical guide for psychologists working in forensic contexts

Examines relevant mental health state legislation relating to criminal, civil and family courts and then sets out a logical structure for writing reports for such matters.

Ethical practice from the perspective of the forensic psychologist : commentary on the uses and value of the Australian Psychological Society (2007) code of ethics

Forensic practice in Australia and around the world attracts a high level of public and judicial scrutiny. The way in which the forensic psychologist conducts him or herself in ethically challenging situations is important not only to the reputation of the individual practitioner, but to the profession more widely. This paper outlines some of the ethical issues that commonly arise in forensic psychology practice and discusses these in relation to the recently published Australian Psychological Society (2007) Code of Ethics. Four ethically challenging scenarios are described and discussed in terms of how the Code might be used to offer guidance to psychologists about how they might best respond.

Changing violent behaviour : forensic mental health and criminological models compared

Evidence-based interventions designed to reduce the risk of re-offending, particularly violent re-offending, are commonly offered in correctional systems around the world. The interventions are often based upon the application of several principles of service delivery that have become widely known as the 'what works' approach to offender rehabilitation. The applicability of these principles to forensic psychiatric services has yet to be determined. The aims are to examine the possible application of the 'what works' approach and its implications for forensic mental health practice. The method used was a review of relevant research from both the general offender and forensic psychiatry literature. The principles underlying the 'what works' approach are likely to have utility in service delivery in forensic psychiatry, particularly when a treatment target is a reduction in risk of harm to others. The individualized models of patient care practiced in forensic psychiatry are also likely to have utility in improving treatment outcomes in correctional settings. The conclusion is that an increased interchange of ideas and interventions between the two areas of practice is likely to be of mutual benefit. This is an area that requires significant development.

Effect of morphine on the growth rate of Calliphora stygia (Fabricius) (Diptera : Calliphoridae) and possible implications for forensic entomology

Insect specimens collected from decomposing bodies enable forensic entomologists to estimate the minimum post-morten interval (PMI). Drugs and toxins within a corpose may affect the development rate of insects that feed on them and it is vital to quantify these effects to accurately calculate minimum PMI.... This suggests that C. sygia is a reliable model to use to accurately age a corpse containing morphine at any of the concentrations investigated.

Clinical and demographic differences between sexually violent predators and other commitment types in a state forensic hospital

Sexual offenders who are involuntarily civilly committed to a secure state hospital as Sexually Violent Predators (SVPs) appear to differ significantly from other current patient populations. Demographically, SVPs are older and more predominantly Caucasian than other patients. They are less frequently psychotic than patients committed under other state statutes such as those found incompetent to stand trial, not guilty by reason of insanity and mentally ill prison transfers. Another salient dimension which distinguishes SVPs is the degree of psychopathy observed in these patients. As a group, SVPs display only slightly higher levels of psychopathy than other patient groups as measured by the revised Psychopathy Checklist. Yet when considered by offender type, rapists are found to have significantly higher average psychopathy scores than other patients, while child molesters are assessed as having lower average psychopathy scores than most other patient commitment categories.

The relationship among malingering, psychopathy, and the MMPI-2 validity scales in maximum security forensic psychiatric inpatients

The records of 392 men hospitalized in a maximum security forensic psychiatric hospital were reviewed. Demographic information was collected as well as data from the men's performance on the Psychopathy Checklist-Revised (PCL-R) and Minnesota Multiphasic Personality Inventory-2 (MMPI-2). Prevalence rates for malingering were low across the sample. However, results of chi-square analysis revealed that those who scored high on the PCL-R received a diagnosis of malingering significantly more frequently than those who scored low on the PCL-R. Clinical applications and theoretical implications of the results are discussed.

Malingering and denial among forensic populations

The issue of malingering and denial is significantly important for clinicians working with forensic clients who are mandated to attend assessments and treatments, or in respect to pre-sentence reports. Four case studies are presented. Explanatory models of defensiveness and malingering are based upon the clients' motivations and include pathogenic, criminalogical and adaptional models.

Synthesis and determination of illicit drugs for improved forensic detection

This research describes the development of several innovative methodologies for the rapid and sensitive determination of analytes of forensic and social significance. The project incorporated separation technology and chemiluminescence (light from a chemical reaction) to determine the active compounds and excipients in illicit drugs and natural products including 'magic mushrooms'

A performance testing framework for digital forensic tools

This thesis surveys the latest development of digital forensic tools designed for anti-cybercrime purposes. It discusses the necessity of testing the digital forensics tools, and presents a novel testing framework. This new testing framework takes the viewpoint of software vendors rather than traditional software engineering approaches.

Robust correctness testing for digital forensic tools

In previous work, the authors presented a theoretical lower bound on the required number of testing runs for performance testing of digital forensic tools. We also demonstrated a practical method of testing showing how to tolerate both measurement and random errors in order to achieve results close to this bound. In this paper, we extend the previous work to the situation of correctness testing. The contribution of this methodology enables the tester to achieve correctness testing results of high quality from a manageable number of observations and in a dynamic but controllable way. This is of particular interest to forensic testers who do not have access to sophisticated equipment and who can allocate only a small amount of time to testing.

Robust performance testing for digital forensic tools

In previous work, the authors presented a theoretical lower bound on the required number of testing runs for performance testing of digital forensic tools. However, experimental errors are inevitable in laboratory settings, occurring as measurement errors or as random errors and can result in practical situations where the number of testing runs is far from the theoretical bound. This paper adapts our former work to tolerate such errors in the testing results. The contribution of our new methodology enables the tester to achieve performance testing results of high quality from a manageable number of observations and in a dynamic but controllable way. This is of particular interest to forensic testers who do not have access to sophisticated equipment and who can allocate only a small amount of time to testing.
