Revised scoring and improved reliability for the Communication Patterns Questionnaire

Area of Science:

• Psychology
• Relationship Science
• Clinical Psychology

Background:

• The Communication Patterns Questionnaire (CPQ) is a key measure for couple communication, particularly the demand/withdraw pattern linked to negative relationship outcomes.
• Existing CPQ scoring uses limited items, potentially impacting psychometric properties like internal reliability.
• Modern psychometric standards require re-evaluation of the CPQ's factor structure and item usage.

Purpose of the Study:

• To re-examine the CPQ's factor structure using advanced analytical techniques.
• To improve the reliability and validity of CPQ scale scores by potentially including more items.
• To validate a revised CPQ factor structure across multiple samples.

Main Methods:

• Exploratory and confirmatory factor analyses were conducted on four distinct samples.
• The study re-evaluated the factor structure of the Communication Patterns Questionnaire (CPQ).
• Item content was analyzed for conceptual consistency with existing subscales.

Main Results:

• A 3-factor solution, comprising constructive communication and two demand/withdraw scales, demonstrated the best fit for the data.
• This 3-factor structure was successfully replicated across independent samples.
• Revised scales, incorporating additional items, showed significantly improved reliability and stronger associations with relationship satisfaction.

Conclusions:

• The revised 3-factor structure of the CPQ offers enhanced psychometric properties and broader conceptual coverage.
• The updated CPQ scales demonstrate improved reliability and stronger links to relationship satisfaction and therapeutic change.
• These findings support the use of the revised CPQ in clinical practice and relationship research.
