The modified cognitive constructions coding system: reliability and validity assessments.

The cognitive constructions coding system (CCCS) was designed for coding clients' expressed problem constructions on four dimensions: intrapersonal-interpersonal, internal-external, responsible-not responsible, and linear-circular. This study introduces, and examines the reliability and validity of a modified version of the CCCS-a version that involves coding clients' problem constructions at the level of speech turn. Results indicate that the modified CCCS generated reliable ratings of clients' problem constructions in 15 sessions of family therapy. Validity was established by comparing 71 subjects' own ratings of over 250 self-generated problem constructions to the ratings of trained CCCS coders. The modified CCCS allows for identifying moment-to-moment changes in clients' problem constructions and, ultimately, examining the impact of therapist behaviors on such changes.
