What is the standard prolonged exposure protocol?

8-15 sessions of 90 minutes each; weekly or twice-weekly sessions; twice-weekly delivery achieves equivalent outcomes in half the time according to RCT evidence.

What does prolonged exposure involve?

In-vivo exposure to trauma reminders, imaginal exposure (recounting the trauma), and post-session processing; based on Foa's emotional processing theory.

How to use this calculator

1
Enter patient clinical data
Enter the patient's age, weight, lab values, vitals, or clinical findings into the Exposure Therapy Session Frequency PTSD input fields.
2
Select the clinical scoring system
Select or confirm the appropriate clinical scoring system or reference range for the patient population.
3
Calculate the clinical score
Press Calculate to compute the clinical score, risk estimate, or diagnostic result.

Formula

Result = f(patient inputs, clinical reference)

patient inputs: Age, weight, height, lab values, vitals, or clinical findings entered into the Exposure Therapy Frequency.
clinical reference: Reference range, scoring system, or population standard the result is compared against.
Result: Computed clinical score, risk estimate, or diagnostic value.

Clinical results are decision-support only and must be interpreted by a qualified clinician.

Glossary and Definitions

Clinical score: A numeric value derived from patient inputs that estimates risk, severity, or diagnostic likelihood for a given condition.
Reference range: The set of values considered normal for a healthy population, used to interpret a calculated result.
Sensitivity: The probability that a positive result correctly identifies a patient with the condition.
Specificity: The probability that a negative result correctly identifies a patient without the condition.
