Subject Characteristics (SC)

The Subject Characteristics (SC) domain is based on the Findings General Observation class and is an extension of the demographics data, including socioeconomic or other broad characteristics. Subject characteristics may be collected periodically over time. Some examples of subject characteristics include education level, marital status, and national origin.

Associations between some subject characteristic tests and response codelists are described in the SC Codetable, available at https://www.cdisc.org/standards/terminology/controlled-terminology.

Example

This is an example CRF used to collect some basic subject characteristics data. There are 2 sections in this example. The questions in the first section focus on whether subject characteristics were collected and the questions in the second section are each subject characteristic collected. For an eCRF, if "No" is selected as the answer to the question in the first section, the second section would not be displayed.
