概要	The Relationship Assessment Scale is a brief, widely used instrument for measuring global relationship satisfaction and quality in romantic partnerships. Developed by Susan Hendrick in 1988 and based on Robert Sternberg's Triangular Theory of Love, the RAS measures the three core components of love: intimacy (emotional closeness and connection), passion (attraction and desire), and commitment (dedication and decision to maintain the relationship). The RAS is valued for its brevity (7 items), applicability across diverse relationship types, and strong psychometric properties.	The Attachment Style Questionnaire is a self-report instrument measuring adult romantic attachment patterns based on attachment theory. Developed following Hazan and Shaver's seminal 1987 work extending John Bowlby's attachment theory to adult romantic relationships, the ASQ assesses individual differences in attachment anxiety (fear of abandonment and desire for closeness) and attachment avoidance (discomfort with intimacy and emotional dependence). The ASQ is used extensively in relationship research, couple therapy, and studies examining how childhood attachment experiences predict adult romantic functioning.
