Depression Scale PHQ-9

Please choose the following answers that best describe your feelings and situation in the past 30 days.

Your responses to the following statements will automatically calculate as you go through the questionnaire. Your total score at the bottom will determine our recommended course of action. Please see the grading scale. If a face-to-face consultation is suggested, please contact us as soon as you can.

This depression scale will help you monitor your level of depression. Please score yourself weekly so you stay healthy. If you score 10 or higher, you will likely need a ketamine “booster” treatment.

5 – 9 > Mild
