The Forensic Outcome Measure (FORUM), is used to measure outcomes in forensic mental health services with the aim to safeguard patients and the public, monitor progress, inform treatment plans and assist in service evaluation and planning.
The instrument is conceptualised to contain two separate, but linked questionnaires: a Patient Reported Outcome Measure (PROM), and a Clinician Reported Outcome Measure (ClinRO).
The FORUM is considered a comprehensive instrument because:
The final outcome framework contained six overarching domains containing 42 individual outcome areas. The domains were ordered according to a suggestion from the PPAG and agreed by the research team. This order moves from more personal, internal and subjective concepts, to those that are more objective and externally determined. It is not however intended to represent a hierarchy of importance.
It should be noted that the items within the PROM & ClinRo do not directly align, as whislt the PROM contains all items from the 6 domain, the ClinRo provides additional questions that assess observational behavior.
All domains and constituent outcome areas are framed in the first person to emphasise the importance of the individual patient’s perspective:
The 20-item PROM and 23 item Clin-RO provides between them include items covering the six domains of About me, My quality of life, My health, My safety and risk, My life skills and My progress. The ClinRO does not include any items from the About me or My quality of life domains, due to their subjective nature, which can only be meaningfully assessed from the patient’s own perspective.
Responses are provided on a 5 item Likert-scale and whilst we do not recommend weighting individual domains, a numerical score can be produced if required. It is up to users how they wish to interpret responses in ways that are most useful to them; further guidance is under development.
More details of the scoring system and administration procedures for FORUM are provided in the FORUM scoring guide/user manual which can be accessed as part of the licensing procedure.
The approach used to develop the FORUM was an iterative process involving multiple, linked components. The development process had three main parts: firstly concept elicitation, secondly concept prioritisation and thirdly drafting and refinement of the new instrument.
All parts of the work were overseen by the research team, supported by a dedicated Patient and Public Advisory Group (PPAG), which included patients who had previously used forensic mental health services and carers of such patients.
The selection of items for inclusion in the initial draft was guided by discussions in the research team, based on the results of the concept elicitation and prioritisation work. The introduction and instructions were designed to be as short and functional as possible. The timeframe for ratings was guided by the expected pace of change in forensic services. The length of stay is long in such services and comprehensive reviews usually take place every six months through the Care Programme Approach (Hare-Duke et al., 2018; Tomlin et al.,2021).
The PROM was then reviewed by the PPAG and revised before undergoing two rounds of cognitive debriefing interviews (CDI) with patients. Patients in Oxford Health NHS Foundation Trust who had participated in the concept elicitation and prioritisation exercise were invited to participate. The CDIs included a ‘thinking aloud exercise’ and a series of verbal probes. The CDIs were informed by a topic guide developed in collaboration with the PPAG. The PROM was revised after each round of CDIs. The CROM was also reviewed by the PPAG and clinicians from a range of professional backgrounds. The final drafts were agreed by the research team and PPAG.
The study was approved by the London – Surrey Research Ethics Committee (Reference
18/LO/0929). All participants provided informed consent to participate.
The development of the FORUM was funded by the National Institute for Health Research (NIHR) through a Doctoral Research Fellowship (DRF-2017-10-019) awarded to Dr Howard Ryland.
