General Description

The GPS comprises 20 items answered in a Likert-like scale ranging from 1 (never) to 5 (always). Total scores vary between 20 and 100, and higher scores indicate more frequent paranoid ideation. In the original study by Fenigstein and Vanable (1992). Results from the CFA of the GPS confirmed a different model than the one-dimensional model proposed by Fenigstein and Vanable, which comprised three dimensions (mistrust thoughts, persecutory ideas, and selfdeprecation).
