What response values are valid for each questionnaire?

PHQ-9 and GAD-7 accept integer responses from 0 to 3 per item. PCL-5 accepts integer responses from 0 to 4 across all 20 items.

How does the tool handle PHQ-9 Item 9?

Any response greater than 0 on PHQ-9 Item 9 triggers an explicit suicide-risk flag in the output for triage awareness.

What is the DSM-5 cluster rule evaluated for the PCL-5?

It checks if symptom thresholds (score ≥ 2) are met across Cluster B (≥1 item), Cluster C (≥1 item), Cluster D (≥2 items), and Cluster E (≥2 items).

What cutpoint ranges indicate severity on the PHQ-9 and GAD-7?

PHQ-9 uses cutpoints at 5, 10, 15, and 20 for mild, moderate, moderately severe, and severe bands. GAD-7 identifies clinical anxiety with a cutoff score of ≥10.

Do these screening results constitute a medical diagnosis?

No. These instruments provide self-report screening and triage scoring only, which must be interpreted by a qualified clinician.

PHQ-9 GAD-7 PCL-5 Anxiety Depression Screen Tutor

Score PHQ-9, GAD-7 and PCL-5 self-report screens with official bands, the PHQ-9 item-9 suicide-risk flag and depression algorithm, and the PCL-5 DSM-5 cluster rule.

Details

What this tool helps you do

Choose a scale and enter responses in item order (0–3 for PHQ-9/GAD-7; 0–4 for PCL-5). The output scores every item, applies the official severity rubric (PHQ-9 cutpoints 5/10/15/20; GAD-7 bands with the ≥10 cutoff; PCL-5 31–33 cutoff without empirical severity ranges), flags any non-zero PHQ-9 item 9, runs the major-depression algorithm (≥5 items at ≥2 with item 9 at ≥1, plus a core item) and the PCL-5 DSM-5 cluster rule (B≥1, C≥1, D≥2, E≥2 items at ≥2). Screening aids triage — they are not diagnoses.
