About This Test

This free online lack of energy test is for adults who feel tired, lethargic or tired all the time and want a quick, research-informed check. In under two minutes, you’ll rate everyday problems linked to fatigue, motivation and mental slips (losing focus, forgetting what you’re doing, small blunders). The screen is CFQ-informed: it draws on the Cognitive Failures Questionnaire (25-item), which measures how often attention, memory and action slips occur during everyday tasks over the past months.

Your result highlights likely severity and explains common lack of energy causes and what to try next. Use it as a starting point—not a diagnosis. If your score is higher, consider a focused medical review and targeted self-help; if it’s lower, small changes can still help (sleep routine, pacing, movement snacks, hydration, nutrition). You can retake the lack of energy test to track change over time, especially if you’re thinking “why am I so tired?” or “why am I always tired and have no energy.”

How the test works

You’ll rate how often you experience: attention slips (easily distracted, losing track mid-task); memory lapses (misplacing items, forgetfulness); action slips (doing the wrong thing by mistake); energy & motivation issues (lethargic, exhausted, tired after routine tasks). Scores map to bands (lower to higher impact) and suggest next steps: sleep and routine tweaks, nutrition and activity ideas.

Scientific basis

Inspired by the Cognitive Failures Questionnaire (CFQ, 25-item )— a widely used self-report measure of everyday slips across attention, memory and action over ~6 months. We adapt CFQ concepts to connect cognitive slips with fatigue / lack of energy experiences in daily life. Diagnosis of medical causes requires clinical assessment.

FAQ:

What does my score mean?

It summarises how often tiredness and everyday cognitive slips show up and suggests next steps.

Is this a diagnosis?

No. It’s a self-assessment. Only a clinician can diagnose medical causes of fatigue.

Why am I so tired / tired all the time?

Common contributors include poor sleep, stress or anxiety, low mood, iron or B12 deficiency, illness recovery, medications, and life stage factors. A clinician can check underlying causes.

What helps lack of energy quickly?

Start with a fixed wake time, daylight exposure, brief movement breaks, hydration, balanced meals and caffeine timing. If fatigue continues, seek a review.

Does this apply to women’s health or pregnancy?

Yes—pregnancy symptoms and perimenopause can affect energy.
