The maximum score for the EQ-5D 5L Level Summary Score (LSS) is 25. This score signifies the highest level of perceived health problems across all dimensions of the questionnaire.
Understanding the EQ-5D 5L Score
The EQ-5D 5L is a widely used, standardized measure of an individual's health status. It assesses health across five key dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each of these five dimensions is evaluated using five possible response levels, allowing for a nuanced description of an individual's health state.Scoring Mechanism
To calculate the Level Summary Score (LSS), a numerical value is assigned to each response level for every dimension: * A response indicating **"no problems"** is assigned a value of **1**. * A response indicating **"extreme problems"** or **"unable to"** is assigned a value of **5**.The individual numerical values from these five dimensions are then summed together to produce a total score. This calculation results in a score range from 5 to 25.
Achieving the Maximum Score
The maximum score of 25 is reached when an individual reports "extreme problems" or "unable to" on *all five* of the EQ-5D 5L dimensions. This means they would effectively score a 5 for each of the five dimensions, resulting in a sum of 25 (5 + 5 + 5 + 5 + 5 = 25). Conversely, the minimum score of 5 represents "no problems" across all five dimensions (1 + 1 + 1 + 1 + 1 = 5).The table below illustrates how the maximum score of 25 is obtained:
| Dimension | Response Level (for Max Score) | Assigned Value |
|---|---|---|
| Mobility | Extreme problems | 5 |
| Self-care | Extreme problems | 5 |
| Usual Activities | Extreme problems | 5 |
| Pain/Discomfort | Extreme problems | 5 |
| Anxiety/Depression | Extreme problems | 5 |
| Total LSS | 25 |
