The purpose of this paper is to review the evidence base for the use of risk formulation in forensic practice settings.

Systematic literature review principles were adopted to identify literature exploring risk formulation in forensic practice settings in relation to offending behaviour.

Data were analysed using a narrative synthesis approach, and commonalities were observed across some of the studies in terms of definitions, outcomes, and implementation, of risk formulation; however, the findings of the review did not provide a definitive account of risk formulation practice in forensic settings. This is due to the narrow scope of the included studies, the small yet diverse samples, the heterogeneity in research aims and the methodological weaknesses apparent within the included studies.

Further research is needed to understand the application and outcomes of risk formulation in forensic practice settings.

Practitioners should be clear about how they are defining, implementing and assessing the outcomes of risk formulation, alongside being mindful of the evidence base when utilising forensic risk formulation in practice.

To the best of the authors’ knowledge, this is the first paper to focus solely on the evidence base for forensic risk formulation in practice.

Some individuals with autism may engage in violent behaviour. Research into autism specific factors (ASFs) that may contribute to violence is limited. The purpose of this paper is to explore the feasibility of use of an ASF framework which was developed to inform risk formulation and treatment needs.

Retrospective identification and evaluation of ASFs in offenders with autism (N = 13) at childhood, time of index offence and in current risk behaviours. The ASFs described in the framework were repetitive behaviours and circumscribed interests; poor social understanding and empathy; sensitivity to sensory stimulation; and disruption to rigid behavioural routines or difficulties coping with change.

There was evidence for all four ASFs being consistently present in childhood, contributing to violent behaviour at the index offence and current risk behaviours in at least one case. Poor social understanding and empathy was often present at both childhood and index offence in all cases. Of the seven cases with offence paralleling behaviour, five had at least one ASF present at each timepoint.

This proof-of-concept study provides initial support that ASFs play a role in offending behaviour of individuals with autism. Clinicians working in specialist and generic forensic services, with an in-depth knowledge of autism, could use the ASF framework to enhance risk assessments and facilitate more targeted treatment planning for offenders with autism in specialist and general forensic services.

To the best of the authors’ knowledge, this study is the first to test the application of the ASF framework in an autistic offending population.

This paper aims to illustrate by means of a case study how HKT-R Spider reference profiles of recidivists and non-recidivists may be supportive in leave decisions.

The authors describe what is known for recidivists and non-recidivists about changes in risk factors during treatment. The HKT-R Spider is introduced. By comparing a case study to group profiles, the authors illustrate how discussions about leave may be rationalised. From a study among 278 patients to explore the profiles, the authors report the inter agreement, and differences between recidivists and non-recidivists of the clinical HKT-R factors. Intra correlation coefficients, Wilcoxon signed ranks test and independent and paired t-tests are applied. To explore which combination of factors are discriminating between both groups, the authors also performed logistic regression analyses at six treatment stages.

The inter agreement reliability and internal consistency of the clinical HKT-R scale were acceptable to good in all six stages studied. The HKT-R Spider and profiles can be used to assist in evidence-informed decision-making about leave.

Globally recidivists had somewhat higher levels of clinical risk factors at all six decision moments, but the interpretation of HKT-R Spiders profiles should always be adapted to the individual’s context.

Applying the HKT-R Spider reference profiles on individual cases may structure and rationalize discussions lead to decisions based on clinical facts.

The current review aims to focus on how risk and protective factors for self-harm in secure mental health hospitals are captured in the literature.

Fifty-seven articles were included in a systematic review, drawn from an initial 1,119 articles, post duplicate removal. Databases included Psycinfo, Psycarticles, Psycnet, Web of Science and EBSCO host. A thematic analysis was used, which included a meta-ethnographic approach for considering qualitative papers.

There was a clear focus on risk factors, with eight identified (in order of occurrence): raised emotional reactivity and poor emotion regulation; poor mental health; traumatic experiences; personality disorder diagnosis and associated traits; increased use of outward aggression – dual harm; constraints of a secure environment and lack of control; previous self-harm and suicide attempts; and hopelessness. Protective factors featured less, resulting in only three themes emerging (in order of occurrence): positive social support and communication; positive coping skills; and hope/positive outlook.

This includes a proposal to move focus away from “risk” factors, to incorporate “needs”, in terms of individual and environmental factors. There is also a need for more attention to focus on developing high quality research in this area.

The research captures an area where a synthesis of research has not been comprehensively undertaken, particularly with regards to capturing protective as well as risk factors.

Rates of self-harm are elevated in prison, and there is limited evidence to support the efficacy of brief risk screening at reception to predict and prevent self-harm. This study aims to examine the predictive validity of the self-harm/suicide screening items embedded in a prison mental health screening tool from two key domains strongly associated with risk: previous suicidal/self-harm behaviour, and recent ideation.

A sample of men and women were screened on entry to prison, with eight screening items covering the two key domains of risk. Follow-up data on self-harm incidents were collected for 12 months post-screening. The predictive validity of individual screening items, item combinations and cumulative screening score was examined for the overall sample and for men and women separately.

Individual screening items across the two domains were all strongly associated with self-harm in the follow-up period, with odds ratios varying from 2.34 to 9.24. The predictive validity of both individual items, item scores and item combinations demonstrated high specificity but low to moderate sensitivity, and modest area under the curves (AUCs). Predictive validity was generally better for men than women; however, differences were not statistically significant.

Identifying those at risk of self-harm in prisons remains challenging and brief universal screening at prison entry should be only one component of a broader prison risk assessment and management strategy.

To the best of the authors’ knowledge, this study is one of very few to prospectively examine self-harm behaviour following risk screening. Predictive validity was examined in a representative sample of individuals in custody, and for men and women separately.
