It evaluates intrusion avoidance negative alterations in cognition and mood and arousal symptoms. Respondents rate the severity of each symptom over the past month using a scale from zero not at all to four extremely. The total score ranges from zero to sixty eight and higher values indicate more significant distress. A commonly used threshold is thirty three which increases the likelihood of clinically relevant PTSD although diagnostic confirmation always requires structured clinical evaluation. PCL Five assists clinicians in monitoring treatment response screening individuals at risk and quantifying symptom progression.
