DESCRIPTION (provided by applicant): Understanding the functional impact of asthma on health-related quality of life (HRQOL) can be substantially improved using item response theory (IRT) and competing objectives of more practical and more precise assessments can be achieved over a wide range of… More

DESCRIPTION (provided by applicant): We seek to extensively advance the technology for measuring health-related quality of life (HRQOL) for adults with diabetes using item response theory (IRT) and computerized adaptive testing (CAT) methods. HRQOL, increasingly accepted as an important outcome in… More

DESCRIPTION (provided by applicant): We have demonstrated that estimates of the functional impact of headaches and their impact on health-related quality of life (HRQOL) can be substantially improved using item response theory (IRT) and competing objectives of more practical and more precise… More

DESCRIPTION (provided by applicant): The project introduces a new approach to standardizing disease-specific assessments of Health-Related Quality of Life (HRQOL) to achieve the advantages of both generic questionnaires, which can be compared across which have greater sensitivity and specificity.… More

DESCRIPTION (provided by applicant): We seek to achieve major advances in the standardization of chronic pain assessments and in the technology used to collect, process and display results. We propose to use: (1) item response theory (IRT) to calibrate widely-used visual analogue (VAS) and… More

DESCRIPTION (provided by applicant): We propose to apply item response theory (IRT) and computerized adaptive testing (CAT) to achieve major advances in the standardization of Chronic Kidney Disease (CKD) health-related quality of life (HRQOL) metrics, in the efficiency of data collection and… More

DESCRIPTION (provided by applicant): We propose a tool for evaluating the functional impact of headaches that uses computerized adaptive testing (CAT) to achieve more practical and more precise assessments by matching the questions to each patient's headache severity level. In previous work, we… More

DESCRIPTION (provided by applicant): Mental disorders are among the most prevalent conditions in the United States, and their burden for the individual and the society is tremendous. Nevertheless, they are still widely under-diagnosed in community based health care systems. One way to help general… More

DESCRIPTION (provided by applicant): Our objective is to achieve a major advance in the technology used to assess patient reported outcomes in heart failure (HF). Numerous questionnaires currently are being used to measure outcomes of HF patients, but scores from these instruments can not be… More

DESCRIPTION (provided by applicant): Development of a Functional Health CAT for Managing Obesity Abstract In recent decades the prevalence of obesity has increased dramatically in the United States, causing a great burden for the individual and society. Al though behavioral factors are among the… More

DESCRIPTION (provided by applicant): With improvements in the survival of patients with HIV and AIDS, maximizing patients' functional status and well-being is increasingly an important treatment goal. Existing instruments for assessing HIV patients' self- reported functional status and well-being… More

DESCRIPTION (provided by applicant): Several recent initiatives have emphasized the importance of developing and testing new technologies to measure patient-reported outcomes (PRO). PRO measures for asthma can be substantially improved using item response theory (IRT), and competing objectives of… More

DESCRIPTION (provided by applicant): This SBIR Phase II project will develop and evaluate a more practical and comprehensive approach to standardizing the self-assessment of disease-specific Health-Related Quality of Life (HRQOL) in the growing population of aging (45+ years) adults with, and… More
