It is particularly useful when evaluating conditions described in the professional literature as Chronic Fatigue Syndrome (CFS), as well as modern functional imbalances linked to stress, overload, and exhaustion.

🔬 What does this questionnaire measure?

The Chalder Fatigue Scale measures your subjective experience of fatigue, in a way that allows quantification of symptoms and tracking changes over time.

It covers two key areas:

• physical fatigue (tiredness, weakness, need for rest, reduced strength)
• psychophysical and mental fatigue (concentration, mental clarity, speech, memory)

This provides insight into:

• whether the fatigue is temporary or chronic
• which aspects of energy are most affected
• how your condition changes during a therapy plan or health protocol

⚠️ Important:
This questionnaire does not provide a diagnosis. However, it is a valuable clinical tool for assessing the severity and dynamics of fatigue, and for monitoring the effects of the measures you take.

🧩 Why is this scale important?

Unlike a general statement such as “I feel tired,” the Chalder scale:
✔️ uses standardized questions
✔️ allows results to be compared
✔️ tracks changes over time
✔️ helps a clinician estimate the true degree of exhaustion

Because of this, it is widely used:

• in clinical practice
• in research
• in monitoring people with chronic fatigue, burnout, and prolonged recovery

📝 How to complete the questionnaire?

The process is simple and requires no medical background:

1. You answer questions about your fatigue and energy over the past 30 days
2. Each question is rated compared to how you used to feel
3. You choose the option that best describes your current condition

👉 Please answer honestly, without trying to downplay or exaggerate symptoms — the goal is a realistic assessment.

⏱️ How long does it take?

⏱️ Completion time: 3–5 minutes

📊 How are the results interpreted?

Your results are expressed as a total fatigue score, which allows:

• assessment of the intensity of subjective fatigue
• differentiation between mild, moderate, and pronounced fatigue
• tracking progress between the initial assessment and follow-up checks

A higher score indicates:

• a greater level of exhaustion
• reduced overall energy capacity
• the need for deeper analysis and a targeted intervention plan

The results serve as a basis for:

• evaluating the effectiveness of the applied protocol
• individualized recommendations
• planning next steps to restore energy and vitality

💚 The HEALTH FORMULA – energy as a marker of health and vitality

In the The HEALTH FORMULA approach, fatigue is not viewed as an isolated symptom, but as a signal that the body’s balance has been disrupted.

👉 Understanding your current energy level is the first step toward restoring it.
