Quality of Life Assessment

Quality of life assessment is the broad category of instruments — both clinical and self-report — that measure overall life satisfaction across physical, psychological, and social domains. It's the umbrella under which tools like the WHO-5, the SF-36, the EQ-5D, and the Wheel of Life all sit.

Context

The field grew out of healthcare in the 1970s and 80s as researchers realized that survival and symptom-free time were not the only outcomes worth measuring. Two patients with the same medical diagnosis can have very different lives; quality-of-life measurement was developed to make that difference visible and trackable. The World Health Organization's WHOQOL instruments (developed in the 1990s) and the SF-36 (Ware and Sherbourne, 1992) are the most widely used clinical examples.

Modern quality-of-life assessment splits into objective and subjective components. Objective measures look at observable conditions: income, housing, physical mobility, social connections, access to healthcare. Subjective measures ask how the person actually feels about their life: satisfaction, meaning, mood, pain. The two often diverge — a person can score well on objective metrics and poorly on subjective ones, or vice versa.

For everyday self-tracking, most people want a tool that's faster than a clinical assessment but more structured than a journal entry. The Wheel of Life occupies that space. It is not a clinical instrument and shouldn't be confused with one — it won't diagnose anything — but it produces actionable signal in five minutes, which is what most people actually use.

A useful sanity check when picking any self-assessment: does the tool change behavior, or does it just produce a number? Clinical instruments often optimize for the second — they need to produce comparable data across populations. Personal-use tools should optimize for the first. The Wheel of Life is built around what you do next; if the tool isn't pointing at an action, it's the wrong tool for the job.

How it connects to the Wheel of Life

The Wheel of Life sits in the broad family of subjective quality-of-life assessments. It trades clinical validity for usability and frequency. LifeWheel pairs the wheel with the WHO-5 specifically so users get both signals — the everyday navigational tool (the wheel) and a validated wellbeing pulse (WHO-5) that can flag when something deeper might be going on.
