Podsumowanie	The Gratitude Questionnaire-Six (GQ-6), developed by McCullough, Emmons, and Tsang in 2002, is a 6-item measure of dispositional gratitude—the tendency to recognize and appreciate the good in one's life. Operationalizing gratitude as a stable personality trait (not just a momentary feeling), the GQ-6 assesses the capacity to notice, appreciate, and be thankful for life's blessings. Research shows that dispositional gratitude predicts well-being, life satisfaction, relationship quality, and resilience independent of personality and optimism.	The Values in Action (VIA) Inventory of Strengths, developed by Peterson and Seligman in 2004, is a comprehensive instrument designed to identify and measure 24 core character strengths organized under six virtues. Grounded in ancient philosophy and contemporary psychology, the VIA shifts the focus from deficits and pathology to human strengths and positive potential. It exists in multiple versions (full 240-item VIA-240, brief 96-item VIA-96, and mobile-optimized formats), making it accessible for research, clinical practice, coaching, and organizational development.
