Quality of life
The general well-being of a person and how they experience their life in terms of comfort, happiness and fulfilment. Factors affecting quality of life include health, relationships, employment and finance.
A questionnaire is a set of questions, often with multiple-choice answers or a scale (from ‘strongly agree’ to ‘strongly disagree’ for instance) to be completed. It can be used to explore attitudes, preferences or personality traits; it may also be used as part of the diagnostic procedure to find out about a person’s behaviour. (See also surveys.)
