The various constructs do not necessarily identify the same population. Hence, throughout the workshop participants struggled with how to measure people with work disabilities people who would apply for SSA benefits and those who would be classified as persons with work disabilities as a result of the SSA benefits decision process.

In light of the volatility evident in the limited empirical literature investigating the error properties associated with measures of disability and work disability, research is needed on the assessment and reduction of measurement error. Nonresponse Error.

MEASUREMENT ERROR Estimates of the population with disabilities appear to vary as a function of the essential survey conditions under which the data are collected, specifically, the mode of data collection, the wording of the specific question, the context of the question, the overall content of the survey as well as the survey's sponsorship, and the nature of the respondent providing the information (self-response versus proxy response)

· Assessment of context on estimates of the population with disabilities. Workshop participants called for experimentation to identify the role of context on estimates, where context is broadly defined, ranging from subjective factors such as mood to objective factors such as the survey sponsor, the questions immediately preceding the disability measures, and even such factors as the weather.

Estimates based on longitudinal designs need to be compared with those based on crosssectional data collection efforts. NONRESPONSE Impact of Nonresponse Error on Estimates of Persons with Disabilities Although no empirical data exist that address the impact of nonresponse on estimates of persons with disabilities, workshop participants speculated that the nature of a person's impairments or disabilities may result in differential non

Objective Measures Workshop participants underscored the need for the development of standardized objective measures of both the physical and social environments. Participants stressed that the measurement of environmental context should examine

The Subjective Measures Similar to the discussion concerning objective measures of environment, workshop participants identified the need to develop subjective measures of both the physical and social environments that either facilitate or limit participation. In addition to research to develop such measures, the discussion concerning the collection of subjective measures of the environment elicited two additional research topics: (1)

The empirical literature examining measurement error associated with specific questions, albeit limited, suggests that items currently used to screen or measure persons with disability are subject to low levels of reliability and are of questionable validity, especially for people with mental illness. The impacts of both coverage error and survey nonresponse on estimates of the population with disabilities and work disabilities have not been addressed in the literature.
