Formula Used in “Depression Screening by PHQ-2 Calculator”
The PHQ-2 (Patient Health Questionnaire-2) is a screening tool designed to assess the presence and severity of depressive symptoms. The formula used in the PHQ-2 involves simple addition of the scores obtained from two specific questions related to the frequency of depressive symptoms over the past two weeks. The formula can be represented as:
Score = Q1 + Q2
Where:
- Q1 = Self-reported score for question 1
- Q2 = Self-reported score for question 2
Step-by-Step Breakdown of the Formula
To accurately calculate the depression score using the PHQ-2, each component of the formula must be clearly understood. Below is a breakdown of each variable in the formula:
- Q1: This refers to the respondent’s reported level of depressed mood over the last two weeks. Possible scores range from 0 to 3:
- 0 = Not at all
- 1 = Several days
- 2 = More than half the days
- 3 = Nearly every day
- Q2: This indicates the frequency of loss of interest or pleasure in activities once enjoyed. Scoring is identical to Q1:
- 0 = Not at all
- 1 = Several days
- 2 = More than half the days
- 3 = Nearly every day
Example Calculation
To demonstrate how to use the PHQ-2 calculator, consider the following example:
Inputs:
| Question | Your Response (Score) |
|---|---|
| 1. Over the last two weeks, how often have you been bothered by feeling down, depressed, or hopeless? | 2 |
| 2. Over the last two weeks, how often have you been bothered by having little interest or pleasure in doing things? | 1 |
Calculation Steps:
- Identify the score for Q1, which is 2.
- Identify the score for Q2, which is 1.
- Add the scores: Score = Q1 + Q2 = 2 + 1 = 3.
Output:
The total score from the PHQ-2 calculation is 3. According to standard guidelines, a score of 3-5 indicates mild depression, which may require monitoring or further evaluation.
