How the PHQ-2 Score is Computed
The calculator assesses two particular symptoms:
- Little interest or pleasure in doing things
- Feeling down, depressed, or hopeless
Each symptom is rated based on the frequency it has been experienced over the past two weeks, with the options being: Not at all (0), Several days (1), More than half the days (2), or Nearly every day (3). The total score is a summation of the values selected for each question, resulting in a range from 0 to 6:
- 0-2: No Depression
- 3-4: Possible Depression
- 5-6: Likely Depression
Understanding the Results
A higher score suggests a higher likelihood of depression. If a score indicates possible or likely depression, it may be advisable to follow up with more detailed assessments such as the PHQ-9, or refer the individual to mental health services for further evaluation and support.
