Collection Period End – The date data collection ended.
Collection Period Start – The date data collection began.
Data Collection Mode(s) – A specific description of the administration method used to collect the data in the dataset.
Data Dictionary – Link to the data dictionary.
Data model URL – World Wide Web location of the UML model for the dataset. This will typically be stored at gforge.nci.nih.gov.
Dataset Name – The title of the dataset.
Data Sharing Capability – The availability of, or access to data based on the use of the instrument.
Data usage agreement and security documents – These documents facilitate appropriate data sharing between and among organizations by addressing legal, regulatory, policy, proprietary, and contractual barriers to data exchange.
Definition of Construct – Meaning of the construct.
Description – Text description of important information concerning the dataset (e.g., purpose, contents, funding).
GEM Measure(s) Used – List of measures documented in GEM included in the dataset.
GEM Construct(s) Referenced – List of constructs with associated GEM measures in the dataset.
Grid-enabled status – Datasets are considered grid-enabled when the documentation and programming related to the data service have addressed the compatibility guidelines established for caBIG so that that dataset will be syntactically and semantically interoperable with other data presented via caBIG data services. These compatibility guidelines include development of a UML (unified modeling language) model that describes the relationships between the common data elements in a domain and curation of the model to ensure that shared vocabularies and standard values and formats have been used to define how data are collected.
Language – The language in which the measure is written.
Keywords – Words or phrases that will assist with the search for a construct, measure, or dataset.
Measurement Development – Changes to original measure; different iterations.
Measure Name - The title by which the instrument is known.
Measure Type - The method by which the data are obtained.
Mode of Administration - A specific description of the administration of a measure.
Number of Items – Number of items in the measure.
Number of Observations – Number of analysis units contained in the dataset.
Organizational Home – Institutional owner or holder of the dataset and all associated documentation.
Preview CQL Statement – This statement, written in caGrid Query Language (CQL), queries the caBIG data service where the dataset of interest is located and returns a brief preview of the data.
Primary Content Area – The field of research for which this measure is most theoretically relevant.
Population – Types of subjects included in the dataset.
Psychometric Properties – The psychometric aspects of the measure including validity and reliability.
Public Availability – The availability of the measure in the public domain.
References – Selected publications concerning or using the construct.
References/Links – Selected publications concerning or using the dataset.
Reliability – The ability of the measure to assess a quality or property consistently.

Secondary Content Area – A field of research for which this measure is also theoretically relevant.
Scoring Method – The specification of how items are combined to create a final score or set of scores.
Similar Constructs – Related terms that represent over-lapping concepts. They overlap to such an extent that rarely would both be measured (e.g., “perceived benefits” and “pros of change”).
Synonyms for Construct – Other terms sometimes used to represent the same construct (e.g., “perceived susceptibility” and “perceived threat”).
Target population - The individuals or group for which the measure is intended.
Theoretical Foundation – The social, psychological, or behavioral theory underlying the construct.
Validity – The degree to which the measure accurately assesses or reflects what it purports to measure.
Version Date – The year that the measure was released for use.
