The study aimed to shorten the Patient Engagement In Research Scale (PEIRS) to 22 items to assess the meaningful engagement of patients and family caregivers in research projects. Results showed that PEIRS-22 had good measurement properties and reliability, making it suitable for standardized assessment of engagement in research across various contexts.
Objective To shorten the Patient Engagement In Research Scale (PEIRS) to its most essential items and evaluate its measurement properties for assessing the degree of patients' and family caregivers' meaningful engagement as partners in research projects. Methods A prospective cross-sectional web-based survey in Canada and the USA, and also paper-based in Canada. Participants were patients or family caregivers who had engaged in research projects within the last 3 years, were >= 17 years old, and communicated in English. Extensive psychometric analyses were conducted. Results 119 participants: 99 from Canada, 74 female, 51 aged 17-35 years and 50 aged 36-65 years, 60 had post-secondary education, and 74 were Caucasian/white. The original 37-item PEIRS was shortened to 22 items (PEIRS-22), mainly because of low inter-item correlations. PEIRS-22 had a single dominant construct that accounted for 55% of explained variance. Analysis of PEIRS-22 scores revealed the following: (1) acceptable floor and ceiling effects (<15%), (2) internal consistency (ordinal alpha = 0.96), (3) structural validity by fit to a Rasch measurement model, (4) construct validity by moderate correlations with the Public and Patient Engagement Evaluation Tool, (5) good test-retest reliability (ICC2,1 = 0.86) and (6) interpretability demonstrated by significant differences among PEIRS-22 scores across three levels of global meaningful engagement in research. Conclusions The shortened PEIRS is valid and reliable for assessing the degree of meaningful patient and family caregiver engagement in research. It enables standardized assessment of engagement in research across various contexts. Patient or public contribution A researcher-initiated collaboration, patient partners contributed from study conception to manuscript write-up.
