Sternberg's Love Scale

I. Origin and Theoretical Foundation

Sternberg's Triangular Love Scale (TLS) was developed based on the Triangular Theory of Love proposed by American psychologist Robert J. Sternberg in 1986. This theory broke away from the single-dimension perspective of traditional love research and, for the first time, deconstructed love into three mutually independent yet interacting core components.

Sternberg believed that perfect love consists of three major components: intimacy, passion, and commitment, and that different combinations of these three form different types of love relationships. The TLS scale developed based on this theory became a standardized tool for quantitatively assessing the quality of love, and is widely used in psychological research, emotional counseling, and intimate relationship assessment.

II. Analysis of the Core Dimensions

The scale comprehensively assesses the state of love across three core dimensions through 45 questions:

• Intimacy: emotional connection and intimacy, expressed as trust, understanding, support, and sharing; the emotional foundation of love
• Passion: physical attraction and emotional impulse, including romance, desire, and sexual attraction; the driving source of love
• Commitment: decision and responsibility at the rational level, including short-term commitment (willingness to develop the relationship) and long-term commitment (maintaining the relationship); the stabilizing guarantee of love

III. Interpretation of the Seven Types of Love

Based on different combinations of the three major components - intimacy, passion, and commitment - Sternberg divided love into seven typical types, each corresponding to a different relationship state and way of getting along:

• 1. Consummate Love: the complete combination of intimacy + passion + commitment, with deep emotional connection, full passion, and firm commitment. This is the most ideal state of love, with spiritual compatibility, romantic excitement, and lasting responsibility and devotion; it can withstand life's storms and always stay fresh and warm.
• 2. Romantic Love: the combination of intimacy + passion, lacking long-term commitment. The love is full of emotional resonance and a romantic atmosphere; you understand each other, are mutually attracted, enjoy the beauty of the present, and are highly compatible spiritually, but you need to plan the future together and establish a stable commitment mechanism to turn romance into lasting companionship.
• 3. Companionate Love: the combination of intimacy + commitment, with somewhat diminished passion. The relationship is built on deep emotional connection and firm commitment; you trust and support each other, warm as family, and stability and rapport are the core strengths. You can rekindle the romantic spark by creating novelty and reliving romantic memories.
• 4. Fatuous Love: the combination of passion + commitment, lacking deep intimacy. You feel strong passion and firm commitment toward the relationship, but it may stem from a momentary impulse, external attraction, or the bonds of duty; it looks stable on the surface but actually lacks spiritual resonance. Slow the pace, communicate and share more, understand each other's inner world deeply, and build true intimacy.
• 5. Liking: only the intimacy component, lacking passion and commitment. You share a good emotional connection, understand and trust each other, and are more like close friends; being together is relaxed and easy, with open honesty, but the relationship may remain at the friendship stage. Take the initiative to create a romantic atmosphere, clarify the definition of the relationship, and upgrade the feeling from 'liking' to 'love'.
• 6. Infatuation: only the passion component, lacking intimacy and commitment. The love is mainly driven by passion; you feel strong attraction and possessiveness toward the other person and easily fall into the thrill of love at first sight, but it is hard to sustain. View the relationship rationally, spend more time understanding the other person's personality and values, and build an intimate connection based on understanding.
• 7. Empty Love: only the commitment component, lacking intimacy and passion. The relationship is sustained only by commitment and may be driven by duty, habit, family pressure, or material considerations, appearing empty, dull, and lacking warmth. We suggest re-examining each other's needs and rebuilding intimacy and passion by participating in activities together, communicating deeply, and cultivating shared interests.

Beyond the seven typical types above, if all three components are weak or uneven, it is considered 'incomplete love', which requires targeted adjustments so that each dimension of love gradually develops in a balanced way.

IV. Target Groups and Scenarios

Sternberg's Triangular Love Scale mainly applies to the following groups and scenarios:

• Individuals in an intimate relationship, for assessing the quality of the current relationship
• Single people or those in a relationship who want to understand their own love patterns and emotional needs
• A tool to assist in diagnosing relationship problems in emotional counseling
• Quantitative analysis of love types and relationship dynamics in psychological research
• Love matching and personality assessment features on social and matchmaking platforms

This scale is a self-assessment tool suitable for adults over 18 who have dating experience or are in an intimate relationship. It can be completed without professional guidance, and the results have good reliability and validity.

V. Features and Advantages of the Scale

• Solid theoretical support: based on the classic Triangular Theory of Love, with a scientific and reasonable dimensional division
• Comprehensive and in-depth assessment: 45 questions comprehensively cover the three core components of love, avoiding the one-sidedness of a single dimension
• Intuitive and easy-to-understand results: the love type is identified through scores, helping users quickly pinpoint the strengths and weaknesses of the relationship
• Wide range of applications: suitable for both personal self-exploration and use as an auxiliary tool in emotional counseling
• Simple and easy to use: self-assessment answering, a 5-level scoring method, a simple process, and moderate time required

VI. Statement of Limitations

Although the TLS scale has many advantages, its limitations should still be noted:

• State dependence: results are influenced by the current relationship stage and emotional state, and may change over time
• Subjective reporting bias: as a self-assessment scale, results may be influenced by an individual's subjective perception and expressive tendencies
• Cultural adaptability: some questions may be influenced by love concepts under different cultural backgrounds
• Not a diagnostic tool: used only to assess the state of love and relationship quality, and cannot serve as a basis for diagnosing emotional disorders

VII. Significance of the Test

Through the Sternberg Triangular Love Scale test, individuals can clearly understand their own love type (such as romantic love, companionate love, consummate love, etc.) and identify their performance across the three dimensions of intimacy, passion, and commitment. This not only aids self-awareness and emotional growth, but also provides direction for improving relationship quality and resolving relationship conflicts, helping individuals better manage intimate relationships and move toward a healthier, more stable emotional life.
