HKT-R Spider reference profiles. A guideline for fact-based decision-making regarding a forensic patients leave

Abstract

Purpose 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. Design/methodology/approach 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. Findings 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. Practical implications 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. Originality/value Applying the HKT-R Spider reference profiles on individual cases may structure and rationalize discussions lead to decisions based on clinical facts.
