Further Validation of the Couple Relationship Scale.

Area of Science:

• Psychology
• Clinical Psychology
• Relationship Science

Background:

• Couple therapy outcome measures are crucial for assessing treatment effectiveness.
• Previous research has initiated the validation of the Couple Relationship Scale (CRS).
• A need exists for psychometrically sound tools to bridge research and practice in couple therapy.

Purpose of the Study:

• To further validate the Couple Relationship Scale (CRS) as a routine outcome measure in couple therapy.
• To assess the psychometric properties of the CRS in a community sample.
• To build upon prior validation research by S. R. Anderson et al. (2022).

Main Methods:

• Confirmatory factor analysis was used to examine the scale's structure.
• Internal consistency reliability was assessed using Cronbach's alpha.
• Concurrent validity was evaluated by correlating CRS scores with established measures of couple functioning, mental health, and well-being.

Main Results:

• The CRS demonstrated a robust single-factor structure with no gender-based measurement invariance.
• The scale exhibited excellent internal consistency reliability.
• Strong concurrent validity was confirmed through significant correlations with related constructs, and scores were largely independent of demographic variables.

Conclusions:

• The Couple Relationship Scale (CRS) is a psychometrically sound instrument for assessing couple functioning.
• The CRS has the potential to enhance the integration of research and practice in couple therapy.
• Further validation studies in clinical populations are recommended to broaden the applicability of the CRS.
