Abstract

Introduction

The Police Rehabilitation and Retraining Trust (PRRT) was established in 1999, in order to address personal concerns by serving and retired officers relating to their time and experiences on the force. In many cases, officers incurred adverse psychological and physical injuries that could hinder their quality of life. PRRT provides the three core services of: psychological therapies, physiotherapy, and new career coaching and development, with the largest demand for psychological therapy services.

Aim

The aim of this study is to provide an analysis of the psychological therapy services based on the Clinical Outcomes in Routine Evaluation (CORE-OM) outcome scores.

Methods

Data for the study were obtained from PRRT, with Ulster University ethical approval (CMFC-22-003). Individual level data were obtained relating to client characteristics, episode details, and test scores. Observations were included only for clients discharged from the service, with at least two recorded CORE-OM scores (Evans, John Mellor-Clark, Frank Mar 2000).

Results

The mean change in psychological distress measured using the CORE score is an overall reduction of 32, and this takes place over an average of 319 days. A paired sample t-test found that there was a statistically significant (p<0.001) difference between the mean first and mean last recorded core score within the episode of care. Analysis shows that almost two thirds of clients (71%) are male. Overall mean age is 50. In terms of the clients’ mental health conditions, these are recorded as PTSD (43%), depression (16%), and anxiety disorder (14%). Most clients have no risk to themselves disclosed (62%), followed by ‘fleeting thoughts’ (34%), with a smaller proportion reporting a plan or intent (4.3%). A majority of clients are discharged with a status of ‘Treatment Completed’ (79%). The most frequent treatments are CBT (66%) and CBT + EMDR (31%).

Conclusions

The results show improvements in client outcome scores through attending the service, as well as differences in the extent of improvement across different client characteristics.
