Abstract
This study examined psychometric properties and feasibility of the Family Psychoeducation (FPE) Fidelity Scale. Fidelity assessors conducted reviews using the FPE fidelity scale four times over 18 months at five sites in Norway. After completing fidelity reviews, assessors rated feasibility of the fidelity review process. The FPE fidelity scale showed excellent interrater reliability (.99), interrater item agreement (88%), and internal consistency (mean = .84 across four time points). By the 18-month follow-up, all five sites increased fidelity and three reached adequate fidelity. Fidelity assessors rated feasibility as excellent. The FPE fidelity scale has good psychometric properties and is feasible for evaluating the implementation of FPE programs. Trial registration ClinicalTrials.gov Identifier: NCT03271242.
Highlights
About one-third of the total population experiences a mental disorder during their lifetime
A Cochrane review concluded that family psychoeducation (FPE) reduced relapses and readmissions over a 12-month period for the clients with a psychotic disorder (Pharoah et al 2010)
The current study aimed to investigate the psychometric properties and clinical use of the Family Psychoeducation (FPE) Fidelity Scale, including item analysis, interrater reliability, interrater item agreement, internal consistency, sensitivity to change, and feasibility
Summary
About one-third of the total population experiences a mental disorder during their lifetime. A large proportion of the population have family members with mental health problems. The development of evidence-based interventions to support family involvement for people with severe mental illness has been a central feature of community-based mental health TIPS – Network for Clinical Research in Psychosis, Stavanger University Hospital, Post box 8100, 4068 Stavanger, Norway.

Rigorous research has demonstrated the value of involving the family early in treatment (Cabral and Chaves 2010; Day and Petrakis 2017; Jeppesen et al 2005; McFarlane 2016; McWilliams et al 2010; Nilsen et al 2016; Nilsen et al 2014; Pharoah et al 2010). The U.S National Implementing Evidence-Based Practices Project included FPE as one of five core practices for routine mental health settings (Drake et al 2001; McHugo et al 2007)
