Free Qustionaires with Automatic Scoring

Our free questionnaires automatically calculate your scores and provide clear interpretations as you complete them. When finished, simply download a professional PDF report—perfect for keeping accurate patient records without any extra effort. For your security and anonymity, no questionaire data is stored on our site at any time.

Questionaires may have different cutoffs for different clinical population. For example, PTSD Checklist for DSM-5 (PCL-5) vary by population and clinical context (see table below). These cutoffs should be interpreted in the context of the specific population, clinical presentation, and comorbidities. Follow-up diagnostic assessment is recommended when scores are near threshold or in high-risk settings.

Bayesian Methods

Post-test odds = Pre-test probability 1 − Pre-test probability × Sensitivity 1 − Specificity
Post-test probability = Post-test odds 1 + Post-test odds
