Study of the discriminative validity of the PHQ-9 and PHQ-2 in a sample of Brazilian women in the context of primary health care.
Perspect Psychiatr Care. 2009 Jul; 45(3):216-27.PP

Abstract

PURPOSE

This study aimed to assess the discriminative validity of the Brazilian version of the Patient Health Questionnaire (PHQ-9) and of its reduced version (PHQ-2).

DESIGN AND METHODS

The sample consisted of 177 women (60 cases of depression and 117 noncases). The SCID-IV was used as the gold standard.

FINDINGS

For the PHQ-9, a cutoff score equal to or higher than 10 proved to be the most adequate for the screening of depression, whereas the best cutoff score for the PHQ-2 was found to lie between 3 and 4.

PRACTICE IMPLICATIONS

The systematic use of these instruments in nursing and in the context of primary health care could favor the early detection of depression.
