No gold standard for ideal or optimal participation emerged; no one defined set or frequency of activities accounted for 'full' participation. Participants described needing to be free to define and pursue participation on their own terms rather than meeting predetermined societal norms. Participation was viewed as both a right and a responsibility, influenced by and ascribed to the person and to the society. Participation does not occur in a vacuum; the environment dynamically influences participation. Implications of this conceptual framing for assessment, research and systems level change to support participation of people with disabilities are discussed.

Objective: To address the need for brief, reliable, valid, and standardized quality of life (QOL) assessment applicable across neurologic conditions. Methods:Drawing from larger calibrated item banks, we developed short measures (8-9 items each) of 13 different QOL domains across physical, mental, and social health and evaluated their validity and reliability. Three samples were utilized during short form development: general population (Internet-based, n ϭ 2,113); clinical panel (Internet-based, n ϭ 553); and clinical outpatient (clinic-based, n ϭ 581). All short forms are expressed as T scores with a mean of 50 and SD of 10.

The need to measure and evaluate orthotics and prosthetics (O&P) practice has received growing recognition in the past several years. Reliable and valid self-report instruments are needed that can help facilities evaluate patient outcomes. The objective of this project was to develop a set of self-report instruments that assess functional status, quality of life, and satisfaction with devices and services that can be used in an orthotics and prosthetics clinic. Selecting items from a variety of existing instruments, the authors developed and revised four instruments that differentiate patients with varying levels of lower limb function, quality of life, and satisfaction with devices and services. Evidence of construct validity is provided by hierarchies of item difficulty that are consistent with clinical experience. For example, with the lower limb function instrument, running one block was much more difficult than walking indoors. The instruments demonstrate adequate internal consistency (0.88 for lower limb function, 0.88 for quality of life, 0.74 for service satisfaction, 0.78 for device satisfaction). The next steps in their research programme are to evaluate sensitivity and construct validity. The Orthotics and Prosthetics Users' Survey (OPUS) is a promising self-report instrument which may, with further development, allow orthotic and prosthetic practitioners to evaluate the quality and effectiveness of their services as required by accreditation standards such as those of the American Board for Certification in Orthotics and Prosthetics that mandate quality assessment.

Background and Purpose-The aims of this study were to examine the frequency, types, and clinical factors associated with medical complications that occur during inpatient rehabilitation and to identify risk factors for complications that require a transfer to an acute care facility. Methods-A cohort of 1029 patients consecutively admitted for inpatient stroke rehabilitation was studied. Demographic and stroke information, impairment, preexisting medical conditions, and admission laboratory abnormalities were recorded. Medical complications, defined as new or exacerbated medical problems, were documented for each patient.Complications that required transfer off rehabilitation were noted. Univariate and multiple logistic regression analyses were used to determine factors that were associated with risk of medical complications and risk of transfer off rehabilitation. Results-Seventy-five percent of patients experienced Ն1 medical complication during rehabilitation.

Purpose To develop a social health measurement framework, to test items in diverse populations and to develop item response theory (IRT) item banks. Methods A literature review guided framework development of Social Function and Social Relationships sub-domains. Items were revised based on patient feedback, and Social Function items were field-tested. Analyses included exploratory factor analysis (EFA), confirmatory factor analysis (CFA), two-parameter IRT modeling and evaluation of differential item functioning (DIF). Results The analytic sample included 956 general population respondents who answered 56 Ability to Participate and 56 Satisfaction with Participation items. EFA and CFA identified three Ability to Participate sub-domains. However, because of positive and negative wording, and content redundancy, many items did not fit the IRT model, so item banks do not yet exist. EFA, CFA and IRT identified two preliminary Satisfaction item banks. One item exhibited trivial age DIF. Conclusion After extensive item preparation and review, EFA-, CFA- and IRT-guided item banks help provide increased measurement precision and flexibility. Two Satisfaction short forms are available for use in research and clinical practice. This initial validation study resulted in revised item pools that are currently undergoing testing in new clinical samples and populations.
