A validity scale, in psychological testing, is a scale used in an attempt to measure reliability of responses, for example with the goal of detecting defensiveness, ...
The validity scales measure the respondent's overall approach to the test, including faking good or bad, exaggeration, defensiveness, carelessness, or random responding. Inconsistency (ICN) is the degree to which respondents answer similar questions in different ways.
Validity scales were retained (revised), two new validity scales have been added (Fs in 2008 and RBS in 2011), and there are new scales that capture somatic complaints. All of the MMPI-2-RF's scales demonstrate either increased or equivalent construct and criterion validity compared to their MMPI-2 counterparts.
The MCMI-IV contains a total of 30 scales broken down into 25 clinical scales and 5 validity scales. The 25 clinical scales are divided into 15 personality and 10 clinical syndrome scales (the clinical syndrome scales are further divided into 7 Clinical Syndromes and 3 Severe Clinical Syndromes).
Each form of the BRIEF parent- and teacher- rating form contains 86 items in eight non-overlapping clinical scales and two validity scales.These theoretically and statistically derived scales form two indexes: Behavioral Regulation (three scales) and Metacognition (five scales), as well as a Global Executive Composite [6] score that takes into account all of the clinical scales and represents ...
The 16PF provides scores on 16 primary personality scales and five global personality scales, all of which are bi-polar (both ends of each scale have a distinct, meaningful definition). The instrument also includes three validity scales: a bi-polar Impression Management (IM) scale, an Acquiescence (ACQ) scale, and; an Infrequency (INF) scale.
[2] [3] The test is scored on 18 scales, three of which are validity scales. Eleven of the non-validity scales were selected by comparing responses from various groups of people. The other four were content validated. [2] However, factor analysis was not used in the development of the test, and many of the scales are highly inter-correlated and ...
E.g. a scale that is 5 pounds off is reliable but not valid. A test cannot be valid unless it is reliable. Validity is also dependent on the measurement measuring what it was designed to measure, and not something else instead. [6] Validity (similar to reliability) is a relative concept; validity is not an all-or-nothing idea.
