Table 2 Overview of psychometric rating criteria

From: An updated protocol for a systematic review of implementation-related measures

Internal consistency Indicates whether several items that purport to measure the same construct actually produce similar scores in the same test [26].
Convergent validity Defined as the degree to which two constructs that are theoretically related are in fact related [26].
Discriminant (divergent) validity Measures the degree to which two constructs that are theoretically distinct are in fact distinct [26].
Known-groups validity Investigates whether distinct groups with differing characteristics can be differentiated [27].
Structural validity Refers to the degree to which all test items rise and fall together, otherwise known as “test structure” [28].
Predictive validity Refers to the degree to which a measure can predict or correlate with an outcome of interest measured at some point in the future [29]
Concurrent validity Assesses whether two measurements taken at the same time are correlated, and the measure under consideration is compared to an established measure of the same construct [29].
Responsiveness Captures the ability of a measure to detect clinically important changes in the construct it measures over time [26]
Norms Measured by sample size, means, and standard deviations of measures and are meant to assess generalizability.
