概要	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 Subjective Well-Being (SWB) Scale is a broad category of brief instruments measuring how satisfied people are with their lives and the frequency of positive and negative emotions they experience. Originating from Diener's foundational work in the 1980s, SWB scales operationalize the recognition that well-being is fundamentally subjective—how people evaluate their lives matters more than external objective conditions. Various forms exist, including the Satisfaction with Life Scale (SWLS), the Subjective Happiness Scale (SHS), and multi-item composites measuring life satisfaction, positive affect, and negative affect.
