The following types of reliability and validity should be established for a multi-item scale: internal reliability, test-retest reliability (if the variable is expected to be stable over time), content validity, construct validity, and criterion validity. Factor analysis is used in the scale development process.
Content validity is most often addressed in academic and vocational testing, where test items need to reflect the knowledge actually required for a given topic area (e.g., history) or job skill (e.g., accounting). In clinical settings, content validity refers to the correspondence between test items and the symptom content of a syndrome.

PCOs implies the use of a questionnaire covering issues and concerns that are specific to a patient. A comprehensive linguistic validation process including cognitive debriefing is vital to demonstrate content validity in translations for use in a U.S. Food and Drug Administration (FDA) submission.
The IMS Question and Test Interoperability specification (QTI) defines a standard format for the representation of assessment content and results, supporting the exchange of this material between authoring and delivery systems, repositories and other learning management systems. It allows assessment materials to be authored and delivered on ...
Content validity is a non-statistical type of validity that involves "the systematic examination of the test content to determine whether it covers a representative sample of the behavior domain to be measured" (Anastasi & Urbina, 1997 p. 114). For example, does an IQ questionnaire have items covering all areas of intelligence discussed in the ...
The construct validation approach that was used to construct the PAI was used to maximize two types of validity: content validity and discriminant validity. To ensure that the PAI maximized content validity, each scale had a balanced sample of items that represented a range of important items for each construct.
Content validity: Good Scores correspond well to DSM-IV somatoform diagnoses from the SCID [28] and General Health Questionnaire-15. [36] Construct validity (e.g., predictive, concurrent, convergent, and discriminant validity) Adequate
