An essential aspect of patient-centered outcomes research (PCOR) and comparative effectiveness research (CER) is the integration of patient perspectives and experiences with clinical data to evaluate interventions. Thus, PCOR and CER require capturing patient-reported outcome (PRO) data appropriately to inform research, healthcare delivery, and policy. This(More)
BACKGROUND The goal of comparative effectiveness research (CER) is to explain the differential benefits and harms of alternate methods to prevent, diagnose, treat, and monitor a clinical condition or to improve the delivery of care. To inform decision making, information from the patient's perspective that reflects outcomes that patients care about are(More)
With the evolution of theory and methods for detecting recalibration, reprioritization, and reconceptualization response shifts, the time has come to evaluate and compare the current statistical detection techniques. This manuscript presents an overview of a cross-method validation done on the same patient sample. Three statistical techniques were used:(More)
BACKGROUND AND OBJECTIVE Persons experiencing changes in their physical health may change their values and rerate the importance of basic elements of health-related quality of life (HRQL), a process known as response shift. Developing an estimator of HRQL that differentiates between objective change and response shift is essential for the interpretation of(More)
OBJECTIVE The interpretability of changes in perceived health status over time is threatened if people experience a response shift. This study assessed whether the recovery process following stroke altered individuals' perceptions of past health status and the impact that change in internal standards (response shift) had on ratings over time. We(More)
IMPORTANCE The American Board of Internal Medicine Foundation Choosing Wisely Campaign recommends against the use of benzodiazepine drugs for adults 65 years and older. The effect of direct patient education to catalyze collaborative care for reducing inappropriate prescriptions remains unknown. OBJECTIVE To compare the effect of a direct-to-consumer(More)
In many studies, assessments of change in self-report measures such as health-related quality of life must account for potential response shift, including reconceptualization and changes in internal standards of measurement. Objective: The objective of our study was to compare healthy controls and individuals with stroke on the extent to which changes in(More)
BACKGROUND AND PURPOSE The Stroke Rehabilitation Assessment of Movement (STREAM) is a relatively new measure of voluntary movement and basic mobility. The main objectives of this study were: (1) to examine the relationship of the STREAM to other measures of impairment and disability and (2) to compare its usefulness for evaluating effects of stroke and(More)
Response shift methods have developed substantially in the past decade, with a notable emphasis on model-based methods for response shift detection that are appropriate for the analysis of existing data sets. These secondary data analyses have yielded useful insights and motivated the continued growth of response shift methods. However, there are also(More)
BACKGROUND Use of theory is essential for advancing the science of knowledge translation (KT) and for increasing the likelihood that KT interventions will be successful in reducing existing research-practice gaps in health care. As a sociological theory of knowledge, social constructivist theory may be useful for informing the design and evaluation of KT(More)
