Relationship Assessment Scale (RAS)
Also known as: RAS, Sternberg Relationship Assessment Scale
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.

When to use it
The RAS is appropriate for couples seeking relationship assessment or therapy, research on relationship satisfaction, and longitudinal studies of relationship development. It is useful for premarital counseling, monitoring change during therapy, and screening for relationship distress in routine clinical care. The brevity makes it ideal for couples who are time-constrained. It is applicable to heterosexual and same-sex couples, though most validation work has been conducted with mixed-gender samples.
Strengths & limitations
- Exceptionally brief (7 items) and quick to administer and score; easily integrated into clinical practice and large surveys.
- Grounded in a well-established theoretical model (Sternberg's Triangular Theory of Love); measures meaningful dimensions of love beyond simple satisfaction.
- Strong psychometric properties; Cronbach α = 0.86–0.95 for total score; high test–retest reliability (r > 0.80).
- Widely available and freely used in research; over 1,000 published studies employ the RAS.
- Global measure of relationship quality; does not assess specific relationship domains (e.g., communication, conflict, finances) that might inform treatment planning.
- Does not measure or screen for intimate partner violence, abuse, or safety; must be supplemented with safety assessment.
- May not be sensitive to detecting smaller changes in relationship satisfaction; more detailed measures may be needed for detailed outcome monitoring.
- Primarily validated in Western samples; cross-cultural norms and interpretation guidelines are limited.
Frequently asked
How do the three RAS subscales (intimacy, passion, commitment) differ?
Intimacy measures emotional closeness, being understood, and feeling bonded; passion measures attraction, desire, and sexual connection; commitment measures the decision to maintain the relationship and invest in its future. Many couples show different profiles—e.g., high passion but low commitment (infatuation) or high commitment but low passion (companionate love). The subscale profile guides therapy: intimacy deficits may require emotional expression work, passion deficits may need to address attraction, and commitment concerns may require discussing future goals.
What does it mean if partners' RAS scores differ significantly?
Discrepancies are common and clinically important. If one partner scores much higher, it suggests that partner feels more satisfied, loved, and committed. This asymmetry often reflects power imbalances, resentment, or different expectations about the relationship. Large discrepancies (15+ points) warrant clinical exploration: Is one partner coerced to rate satisfaction highly? Does the lower-scoring partner fear leaving? Are they truly unhappy, or differently expressive?
How does the RAS differ from the Dyadic Adjustment Scale (DAS)?
The RAS (7 items) is much briefer and measures love components (intimacy, passion, commitment) and global satisfaction. The DAS (32 items) is more comprehensive, measuring consensus, satisfaction, cohesion, and affectional expression. The RAS is ideal for rapid screening and longitudinal tracking; the DAS provides richer diagnostic information about specific areas of couple functioning. Some researchers use both.
Can the RAS be used to assess same-sex couples?
Yes. The RAS has been validated in same-sex couples and shows equivalent reliability and factor structure to heterosexual samples. However, most normative data derive from heterosexual couples; cutoff scores may differ for same-sex relationships due to different cultural norms and relationship contexts. Interpret RAS scores in same-sex couples with awareness of these contextual differences.
Is a high RAS score always good? Can high scores hide problems?
Generally, higher RAS scores indicate healthier relationships; however, some couples experiencing control, coercion, or hidden violence may report high satisfaction due to fear, shame, or distorted perceptions. Always supplement RAS with clinical interview and observation. A high RAS in a couple reporting no arguments should prompt inquiry into whether they are suppressing conflict or whether one partner controls the other.
