Psychometric evaluation of the Hopkins Rehabilitation Engagement Rating Scale in postacute physical therapy services

PURPOSE/OBJECTIVE Evaluate the reliability and validity of the Hopkins Rehabilitation Engagement Scale (HRERS) in a postacute rehabilitation sample. We hypothesized that HRERS items would comprise a single factor, and would demonstrate adequate internal consistency and temporal stability, and significant relationships with key constructs. Research Method and Design: Retrospective medical record review between 2016 and 2017 of older veterans (N = 107) admitted to a community living center postacute care (CLC-PAC) rehabilitation hospital unit to address targeted physical therapy rehabilitation goals. Inclusion criteria included availability of two HRERS administrations at Time 1 (admission) and Time 2 (approximately one-month follow-up or physical therapist/CLC-PAC discharge). RESULTS Across timepoints, HRERS items reflect a single factor of engagement, and the scale has good internal consistency at admission (Time 1, α = .759) and follow-up (Time 2, α = .877). The temporal stability of HRERS across ratings was r = .56 (p < .001). Increased pain rating (r = -.309, p < .01) and depressive symptoms (-.287, p < .01) at admission correlates with subsequent physical therapist (PT) engagement (HRERS Time 2). Low admission PT engagement correlates with less frequent PT attendance (r = -.242, p < .01) and greater number of consults placed during the CLC stay (r = -.222, p < .05). CONCLUSIONS/IMPLICATIONS HRERS is a reliable and valid measure of PT engagement in older CLC-PAC Veterans. Findings support the administration of the HRERS at more than one timepoint during rehabilitation to inform interventions targeting select behavioral health factors such as pain and depression.
