The Forensic High and Intensive Care Monitor: Measurement Properties of a Model Fidelity Scale for Contact-Based Care in Forensic Psychiatry

Forensic High and Intensive Care (FHIC) has recently been developed as a new care model in Dutch forensic psychiatry. FHIC aims to provide contact-based care. To support Dutch forensic care institutions in the implementation of the model, a model fidelity scale was developed called the FHIC monitor. The aim of this study was to assess the inter-rater reliability, content validity, and construct validity of the FHIC monitor. A multi-methods design was used, combining qualitative and quantitative research. To collect data, audits and focus group meetings were organized to score care at individual wards with the monitor and get feedback from auditors and audit receiving teams about the quality of the monitor. In total, fifteen forensic mental healthcare institutions participated. The instrument showed acceptable inter-rater reliability and content validity, and a significant difference between expected high and low scoring institutions, supporting construct validity. The instrument can be used as a valid instrument to measure the level of implementation of the FHIC model on forensic psychiatric wards in the Netherlands.
