Scoring and interpretation

Answers are scored on a 4-point Likert scale from 0 to 3 with 0 for "Never" to 3 for "All the time." Scores are summed and total scores range from 0 to 18. Higher scores are associated with higher levels of PTSD symptoms. A score of 4 or greater is considered clinically significant.

Reliability and validity

The validation of the CATS showed good psychometric properties and has proven good to excellent internal consistency of the symptom scales with α ranging between .88 - .94 for the different versions.
