Quality of life and its measurement: important principles and guidelines

From a measurement perspective the use of the QOL construct is changing. Initially it was used as a sensitizing notion, social construct, and unifying theme. Increasingly, it is being used as conceptual framework for assessing quality outcomes, a social construct that guides quality enhancement strategies, and a criterion for assessing the effectiveness of those strategies. This new role places additional emphasis on the valid assessment of one's QOL.
