[Coding/Special Scores] PSV

Aliases

PSV
perseveration
perseverative responding

Definition

PSV is coded when the subject perseverates and repeats the same response or same kind of response in a rigid way.
It does not refer to simple consistency; it points to stereotyped or mechanical repetition.

Conditions

Consider it when the same response or a very close pattern is repeated perseveratively.
It may appear within the same card or across multiple cards.
The important point is not simple similarity alone, but the quality of rigid repetition.
The later interpretive meaning connects with result-interpretation/lower-section/processing/PSV.

Cautions

A similar response based on economy or preference is not enough by itself for PSV.
Coding requires insistent or mechanical repetition, not merely a stable style.
PSV marks the presence of perseveration; it does not by itself explain its cause.
