Statistical disclosure control (SDC), also known as statistical disclosure limitation (SDL) or disclosure avoidance, is a technique used in data-driven research to ensure no person or organization is identifiable from the results of an analysis of survey or administrative data, or in the release of microdata. The purpose of SDC is to protect ...
Researchers publish data that they get from participants. To preserve participants' privacy, the data goes through a process to de-identify it. The goal of such a process would be to remove protected health information which could be used to connect a study participant to their contribution to a research project so that the participants will not suffer from data re-identification.
The Medical Expenditure Panel Survey currently uses the NHIS sampled population to form its own sampling frame (ultimately sampling one-half of NHIS respondent households for its own publicly available complete survey). [2] After filling out a confidentiality agreement, AHRQ provides a crosswalk to merge these data. [13]
Incentives to take a survey should be used sparingly. [9] Questionnaires should have the option to be anonymous. [5] Confidentiality must be imposed on certain questionnaires. Identification may be required on questionnaires that need follow up. Although, in this case the administrator may choose to use identifying numbers rather than names.
Randomised response is a research method used in structured survey interview. It was first proposed by S. L. Warner in 1965 and later modified by B. G. Greenberg and coauthors in 1969. [1] [2] It allows respondents to respond to sensitive issues (such as criminal behavior or sexuality) while maintaining confidentiality. Chance decides, unknown ...
The Consumer Expenditure Survey was first collected over 130 years ago in 1888. It became a continuous survey in 1980. From the late 1800s until 1980 the survey had been administered at approximately ten-year intervals. [6] More information about the history of the Consumer Expenditure Survey is available on the program's history page.
Outline the purpose of the survey, along with an estimate of the time needed to complete the survey. Promise confidentiality and anonymity to the respondent of their answers and opinions. Let the respondent know that participation in the survey is of their own free will. Ask for permission to begin the survey. [14]
These traits mean the sample is systematically different from the target population, potentially resulting in biased estimates. [ 1 ] For instance, a study found that those who refused to answer a survey on AIDS tended to be "older, attend church more often, are less likely to believe in the confidentiality of surveys, and have lower sexual ...
