• A. There Are Four Main Scales and Three Extras.
• B. There Are Five Main Scales and Two Extras.
• C. There Are Four Main Scales and Three Extras.
• D. There Are Three Main Scales and Four Extras.

Answer: (C)

The test includes a set of validity checks to determine whether the responses can be trusted, which is crucial before interpreting any clinical scales. There are four main validity scales that cover the common ways people might distort a personality report: Infrequency catches unusually rare endorsements or random answering; Inconsistency looks for unstable or conflicting responses across related items or test halves; Negative Distortion reveals a tendency to underreport problems or present oneself as better than one actually is; Positive Distortion detects exaggeration or feigning of symptoms, sometimes to appear worse or to manipulate the assessment. In addition, there are three supplementary validity scales that provide extra angles on response style. So, the statement that there are four main scales and three extras reflects the standard structure of the PAI validity system. This framework helps ensure that the subsequent interpretation of the content scales is based on a credible, accurate profile.
