GOUVEIA, Valdiney V. et al. The use of the GHQ-12 in a general population: a study of its construct validity. Psic.: Teor. e Pesq. [online]. 2003, vol.19, n.3, pp. 241-248. ISSN 0102-3772. http://dx.doi.org/10.1590/S0102-37722003000300006.
This study aimed to know the GHQ-12's construct validity in a general, non clinical population. 306 volunteers from different districts in Joao Pessoa, with a mean age of 34 years (SD = 13.8; ranging from 18 to 84), equally distributed with regards to gender (152 men; 154 woman), predominantly high school students (42.5%) participated in the study. They answered a questionnaire in which three measures were incorporated: Satisfaction with Life Scale, Positive and Negative Affects Scale, and General Health Questionnaire (GHQ-12). Results indicated that this measure can be considered as bifactorial, with anxiety (a = .66) and depression (a = .81) as the two factors. As expected, both factors correlated with the Satisfaction with Life Scale and the Positive and Negative Affects Scale, indicating the construct validity of the GHQ-12. These results are discussed and compared with results of previous studies suggesting a multidimensional structure for understanding mental health in the general population.
