Individual Placement and Support for Patients With Offending Histories (IPSOH)

This is a feasibility trial which aims to assess the feasibility of conducting a full Randomized Controlled Trial (RCT) to evaluate the effectiveness of Individual Placement and Support (IPS) in improving employment rates and associated psychosocial outcomes in forensic psychiatric populations.

Given that IPS is a complex intervention, the design of this study has drawn from the principles set out in the UK Medical Research Council (MRC) Guidance on developing and evaluating complex interventions by defining three major research strands in order to achieve the specific objectives of the study as follows:

A. Implementation of IPS in community forensic services: The specific objective of this strand is to embed the IPS model in the community forensic services in which the feasibility study will be carried out (aided by an IPS Expert), by bringing an employment specialist into clinical teams, raising awareness about IPS within the organization, forming links with IPS services in the area and developing links with employers, as well as conducting IPS fidelity reviews.

B. Feasibility Cluster Randomized Controlled Trial (RCT): The specific objectives of this strand are to estimate the parameters required to design a full RCT including:

1. Means and standard deviations of the key outcome measures in order to benchmark potential effect sizes and enable sample size calculations.
2. The feasibility of randomization, recruitment and retention rates to the IPS and controls;
3. The suitability of the key outcome measures with respect to: reliability, acceptability, and distribution of the scores.

C. Process Evaluation: This will be carried out in parallel with the other two strands to meet other specific objectives by using the following methods:

1. Qualitative interviews with staff to identify the structural, legal, organizational and individual-level to barriers and facilitators to implementation of IPS in community forensic services.
2. Fidelity Reviews to assess the extent to which the services follow the principles of IPS and to assess how well the employment specialist functions within the community forensic services.
3. Qualitative interviews with patients assigned to IPS in order to assess their general views of IPS, benefits from participating, disadvantages from or dislikes about participating and barriers and facilitators to implementation.
