Podsumowanie	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 Dyadic Adjustment Scale is the most widely used self-report instrument for measuring the quality of relationships in married or cohabiting couples. Developed by Graham Spanier in 1976, it captures four fundamental dimensions of relationship functioning: consensus (agreement on key domains), satisfaction (contentment in the partnership), cohesion (togetherness and shared activities), and affectional expression (intimacy and passion). The DAS has become a gold standard in couple therapy research, relationship satisfaction studies, and marital intervention trials.
