The clinical profile of high-risk mentally disordered offenders

A Latent Class Analysis of Forensic Psychiatric Patients in Relation to Risk and Protective Factors

Forensic psychiatric patients form a very heterogeneous population regarding psychopathology, criminal history, and risk factors for reoffending. Therefore, the present study aimed to investigate whether there are more homogeneous classes of forensic patients based on DSM-IV-TR Axis I and II diagnoses and previously committed offenses, by means of explorative latent class analysis (LCA). It was also investigated which risk and protective factors are significantly more prevalent in one class compared to other classes. The study sample contained 722 male forensic psychiatric patients who were unconditionally released between 2004 and 2014 from high-security forensic clinics. Data were retrospectively derived from electronic patient files. Five distinctive patient classes emerged: class with only Axis II diagnosis, class with multiple problems, antisocial class, psychotic class, and intellectually disabled class. These classes differed significantly in risk and protective factors. This study contributes to the understanding of patient classes and provides directions for future, class-tailored interventions.

Patient Profiles in Dutch Forensic Psychiatry Based on Risk Factors, Pathology, and Offense

Forensic psychiatry embodies a highly heterogeneous population differing widely in terms of diagnoses, crimes committed, and risk factors. All of these are vitally important for treatment indications and should be accounted for in research. However, there is limited empirical knowledge of patient profiles. This study constructed patient profiles on the basis of the three domains mentioned above. Participants were found guilty of having committed crimes due to psychiatric disorders and were admitted to Forensic Psychiatric Center (FPC) 2landen or FPC De Kijvelanden in the Netherlands. Retrospective data were retrieved from patient files. Diagnoses were assessed according to the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV-TR) criteria and risk factors according to the Historical Clinical Future-30 (HKT-30) instrument. Latent class analysis was conducted to define typologies; external variables were included for validation. Four different classes or "patient risk profiles," with varying psychopathologies, risk factors, and crimes, were identified. Results were consistent with previous studies, and external validation with the Psychopathy Checklist-Revised (PCL-R) two-factor model and the four facets of the PCL-R agreed with results found. Results display specific risk factors for specific psychopathology/offense combinations.

The evaluation stage of the Hoeven Outcome Monitor (HOM): Towards an evidence based groundwork in forensic mental health

This study examined if a macro-, meso-, and micro outcome measurement instrument that constitutes the evaluation stage of a Dutch forensic psychiatric outcome monitor, the Hoeven Outcome Monitor (HOM), can provide a first step towards a more evidence based groundwork in forensic mental health. General, serious, very serious, special, and tbs meriting recidivism during treatment, after treatment, and overall were charted for forensic psychiatric patients discharged from a Dutch forensic psychiatric centre between 1999 and 2008 (N=164). Re-conviction data were obtained from the official Criminal Records System, and the mean follow-up time was 116.2months. First, the results showed that the macro-measurements provide comparative outcome measures to generate insight into the overall effectiveness of forensic psychiatric treatment. Second, the meso-measurements yielded clinically relevant treatment outcome data for all discharged patients to generate a complete view of treatment effectiveness. Finally, the micro-measurements allowed access to detailed patient and treatment effectiveness assessments that provides the empirical foundation to conduct aetiological research into the prediction and control of high-risk behaviour. Thus, an outcome measurement instrument in line with Evidence Based Medicine and best practice guidelines was designed that provides an empirically sound evaluation framework for treatment effectiveness, and an impetus for the development of effective interventions to generate an evidence based groundwork in forensic mental health.

Coercion, competence, and consent in offenders with personality disorder

Competence to consent to treatment has not previously been examined in a personality disorder cohort without comorbid mental disorder. We examined competence and coercion in 174 individuals diagnosed with severe personality disorder using two validated tools (the MacArthur Competence Assessment Tool for Treatment and the MacArthur Coercion Assessment Scale - Short Form). Competence was not categorically impaired, but there were variations within the sample on dimensional competence measures. Further, there were significant negative correlations between experienced coercion and competence. Higher coercion scores were associated with two components of competence: lower understanding and reasoning. Patients who consented to treatment had higher scores on competence measures and experienced less coercion. These findings suggest that therapeutic approaches that decrease experienced coercion and increase competence may increase the engagement of individuals diagnosed with severe personality disorders in treatment.
