The factor structure of the 4-item Perceived Stress Scale in English adolescents.

This study investigated the factor structure, internal consistency, and known-groups validity of the 4-item Perceived Stress Scale in a large sample of 29,388 English adolescents. Results indicated that the original unidimensional structure was not viable and instead provided support for a two-factor structure. Examination of a bifactor-(S − 1) model indicated that this multidimensionality can be attributed to reverse-worded items; however, beyond method effects, these factors appear to capture distinct, though inter-related, constructs. As this multidimensional structure relies on 2-item factors, we advise use of longer versions of this measure where possible. (PsycInfo Database Record (c) 2020 APA, all rights reserved)
