This study aims to adapt the Gratitude Questionnaire (GQ-6) to the Philippines, gathering evidence of its validity and reliability. Two studies were conducted. Participants in Study 1 were 340 college students (Mage= 20.63; 62.1% female), who completed the GQ-6 and demographic questions. The exploratory factor analysis was performed, indicating a one-factor solution (a= .80). Participants in Study 2 were 813 college students (Mage= 19.99 years; 50.1% male), who answered the GQ-6, the Life Orientation Test-Revised, the Subjective Happiness Scale, and the Spirituality/Religiousness items. Results corroborated the one-factor structure (e.g., CFI= .98, RMSEA= .05) showing evidence of its association with life orientation (r= .29), subjective happiness (r= .08), and religiosity (r= .31). The scores from the GQ-6 also exhibited invariance across gender. In conclusion, the GQ-6 provide evidence of factorial and criterion validity and reliability, justifying its use in the Philippines.
