title: Developing a measurement of engagement: the Residential Rehabilitation Engagement Scale for psychosis.
abstract: BACKGROUND
  In this study, we extend the measurement of engagement begun in community assertive outreach to an in-patient rehabilitation population.
  
  
  OBJECTIVE
  We report the development of the Residential Rehabilitation Engagement Scale (RRES), which measures engagement in the context of the broader multidisciplinary team and the overall rehabilitation process.
  
  
  METHODS
  Twenty-six patients were assessed using the RRES to determine inter-rater reliability and test-retest reliability. A larger sample (N  =  92) was utilised to explore the internal consistency of the scale and to perform cluster analysis to examine item structure.
  
  
  RESULTS
  The RRES demonstrated good inter-rater reliability, test-retest reliability and internal consistency. Cluster analysis revealed three independent potential subcategories of engagement.
  
  
  CONCLUSIONS
  The RRES is a reliable measure of engagement, consisting of three potential dimensions: active participation and openness, agreement with treatment and basic relationships and medication compliance. The relevance of the findings to in-patient rehabilitation settings and clinical implications is discussed.
