Background/Description
The Couples Satisfaction Index (CSI) is a widely used self-report measure designed to assess the level of satisfaction individuals experience in their romantic relationships. It is considered one of the most reliable and valid tools for evaluating relationship quality, making it a valuable resource for researchers, clinicians, and couples seeking to understand and improve their partnerships.
The CSI was developed to address limitations in earlier relationship satisfaction measures, such as the Dyadic Adjustment Scale (DAS). It offers a more nuanced and comprehensive assessment by focusing on emotional, cognitive, and behavioral aspects of relationship satisfaction. The scale is particularly useful in clinical settings, where it helps therapists identify areas of concern and track progress over time.
The CSI is suitable for use with diverse populations, including married couples, cohabiting partners, and individuals in long-term relationships. Its brevity and ease of administration make it a practical tool for both research and clinical practice.
Administration, Scoring and Interpretation
- Obtain the copy: Secure a licensed or authorized version of the CSI from reputable sources, such as academic publishers or psychological assessment databases.
- Explain the purpose: Inform participants that the CSI is designed to measure their level of satisfaction in their romantic relationship. Emphasize that there are no right or wrong answers.
- Provide instructions: Ask participants to respond to each item honestly, based on their current feelings and experiences in their relationship.
- Approximate time: The CSI typically takes 5–10 minutes to complete, depending on the version used (e.g., 32-item, 16-item, or 4-item versions).
- Administer the scale: Distribute the CSI in a quiet, comfortable environment, either in paper-and-pencil format or digitally, depending on the setting.
Reliability and Validity
The CSI has demonstrated strong psychometric properties across multiple studies:
- Reliability: The scale exhibits high internal consistency, with Cronbach’s alpha coefficients ranging from 0.94 to 0.98, depending on the version used. Test-retest reliability is also robust, indicating stability over time.
- Validity: The CSI has excellent construct validity, correlating strongly with other measures of relationship satisfaction, such as the Dyadic Adjustment Scale (DAS). It also discriminates effectively between satisfied and dissatisfied couples, making it a sensitive tool for detecting changes in relationship quality.
