The CDASH Model establishes a standard way to collect data across studies. Guidance in this section implements the CDASH Model and provides:

  • Basic standards and best practices for data collection.
  • Guidance for development, management, and use of case report forms (CRFs).

The TIG standard directly addresses development of CRFs but does not formally address data collected via other sources. However, the principles and metadata presented can be applied to eSource (also known as "non-CRF") data, such as vendors' electronic data transfer standards and ePRO data structures, as applicable.

In practice, there is variety in language used to describe operational concepts used as part of data collection. for consistency language shown below is used throughout this section and should be interpreted as specified.

NumLanguageRefers to:
1CRF
  • Both paper CRFs and electronic CRFs (eCRFs) unless otherwise specified.
2Data Collection Field(s)
  • Data elements that are commonly on the CRF.
3Data Collection Variable(s)
  • Data elements stored in an electronic data capture (EDC) system.  
4Mechanisms for data collection
  • Refers collectively to different approaches used to control how data are collected including tick boxes, checkboxes, radio buttons, and drop-down lists.
