Abstract

This paper aims to adapt the Gratitude Questionnaire (GQ-6) to Brazil, gathering evidence of its validity (factorial and criterion) and reliability. Two studies were carried out. Participants in Study 1 were 471 undergraduate students (Mage = 22.8; 59.2% females), who answered the GQ-6 and demographic questions. To conduct exploratory (EFA) and confirmatory (CFA) factorial analyses, respectively, this sample was split in two (n1 = 226; n2 = 245). The EFA (Hull method) indicated a one-dimensional solution (α = 0.87), which was corroborated by CFA (e.g., CFI = 0.99; α = 0.72). Participants in Study 2 were 515 undergraduate students (Mage = 23.1; 56.6% females), who answered the previous instruments, the 12-item Purpose of Life Test, and the Multi-Attitude Suicide Tendency Scale. Results corroborated the one-factor structure (e.g., CFI = 0.97; α = 0.71), showing evidence of criterion validity (p <.001) of the GQ-6 with meaning of life [existential lack (r = −.50) and personal achievement (r =.52)] and attitudes towards life [attraction to life (r =.44) and repulsion by life (r = −.49)]. In conclusion, the GQ-6 showed evidence of validity (factorial and criterion) and reliability, justifying its use in Brazil.
