To fully capture the impact of a disease or condition on the lives of individuals, patient-reported outcomes are considered a necessary component of health measurement in rehabilitation. This article provides an overview of the involvement of rehabilitation stakeholders in the development of sound measurement tools for the Patient-Reported Outcomes Measurement Information System (PROMIS), a National Institutes of Health-funded initiative. PROMIS is a multisite study that included many different populations. We focus on the involvement of people with several chronic conditions, including multiple sclerosis, spinal cord injury, and arthritis, in the development of PROMIS measures. We describe both qualitative and quantitative methods used, including expert panels, focus groups, cognitive interviews, and item response theory modeling, which resulted in enhanced utility of PROMIS measures in rehabilitation. Measures include a set of global health items and 12 item banks representing 6 domains. Scores are reported in the T score metric (mean ± SD, 50 ± 10) and centered on mean values from the U.S. general population. The PROMIS item banks measure quality of life and symptoms of people with chronic conditions and have the potential to enhance research and clinical practice by facilitating comparisons of scores across domains and populations.

    ABSTRACT: To develop a spinal cord injury (SCI)-specific patient-reported outcome (PRO) measure of health-related quality of life (QOL) covering multiple domains of functioning, including physical, emotional, and social health. Focus groups. Four SCI Model Systems rehabilitation hospitals. Individuals with SCI (n=65) and clinicians (n=42). Not applicable. Spinal Cord Injury Quality of Life Measurement System (SCI-QOL). Qualitative analysis yielded 3 domains of primary importance: physical-medical health, emotional health, and social participation. Results were used to guide domain and item decisions in the development of the SCI-QOL PRO measurement system. Qualitative data were used to develop item pools with item content specific to individuals with SCI across a wide spectrum of functioning. When possible, items from other major measurement initiatives were included verbatim in the item pools to link the measurement systems and facilitate cross-study and cross-population comparisons. Issues that affect individuals' QOL after SCI are varied and several issues are unique to individuals who have had a traumatic injury. From these qualitative data, 3 major domains and 18 subdomains of functioning were identified. Item pools were developed in each of these 18 areas to measure functioning related to physical-medical issues, emotional status, and social participation.

    ABSTRACT: This 2-part qualitative study explored health-related quality of life (HRQOL) in individuals with traumatic brain injury (TBI). A community-based participatory action research design was used, which emphasizes collaboration between researchers and individuals with disabilities to ensure that results are relevant for individuals with TBI. In study 1, community members (N=20) with TBI served as "experts" during 1-on-1 semistructured interviews, reviewing current HRQOL items and identifying HRQOL issues commonly experienced by individuals with TBI. Each participant identified at least 31 issues, with most generating more than 90 responses, highlighting the multifaceted nature of HRQOL in TBI. Study 2 consisted of 7 patient/consumer groups (33 individuals with TBI), 4 caregiver groups (17 caregivers), and 2 provider groups (15 providers). Qualitative analysis of patient focus groups indicated that 48% of focus group comments were related to emotional issues; 23%, to social functioning; 14%, to physical functioning; 11%, to cognition; and 7%, to personality changes (caregiver and provider focus group analysis indicated identical patterns of findings). In addition, both studies evaluated the applicability in TBI of generic items developed by the Patient-Reported Outcomes Measurement Information System and the Neurology Quality of Life Measurement initiative. Findings suggest that although there is some overlap between current generic measures of HRQOL and concepts reported by individuals with TBI, these generic measures do not capture the full complexity of HRQOL in TBI. TBI-targeted item banks are needed to ensure sensitive assessment of HRQOL in TBI.

    ABSTRACT: The articles in this supplement present recent advances in the measurement of patient-reported health-related quality-of-life (HRQOL) outcomes. Specifically, these articles highlight the combined efforts of the National Institutes of Health, National Institute for Neurological Disorders and Stroke, National Center on Medical Rehabilitation Research, National Institute on Disability and Rehabilitation Research, and Department of Veterans Affairs Rehabilitation Research and Development Service to improve HRQOL measurement. In addition, this supplement is intended to provide rehabilitation professionals with information about these efforts and the implications that these advances in outcomes measurement have for rehabilitation medicine and clinical practice. These new measurement scales use state-of-the-art method techniques, including item response theory and computerized adaptive testing. In addition, scale development involves both qualitative and quantitative methods, as well as the administration of items to hundreds or even thousands of research participants. The scales deliberately have been built with overlap of items between scales so that linkages and equivalency scores can be computed. Ultimately, these scales should facilitate direct comparison of outcomes instruments across studies and will serve as standard data elements across research trials without compromising the specificity of disease- or condition-targeted measures. This supplement includes the initial publications for many of these new measurement initiatives, each of which provides researchers and clinicians with better tools for evaluation of the efficacy of their interventions.
