DIALOG Scale

DIALOG is a scale of 11 questions. Patients rate their satisfaction with eight life domains and three treatment aspects on a 7-point scale. DIALOG provides a score for subjective quality of life and a score for treatment satisfaction.

The scale has been shown to have good psychometric properties and is widely used in both routine care in the NHS and research. One major strength is that in contrast to conventional psychological tests, every single item is meaningful and can be interpreted (and not just the mean score of items). It can be used to evaluate treatment on the level of individuals, groups and services.

Scoring the scale: 

The mean of the eight items on satisfaction with different life domains forms the subjective quality of life score. The mean of the three items on satisfaction with treatment components forms the treatment satisfaction score. Scores below four reflect explicit dissatisfaction, whereas scores above four reflect explicit satisfaction. Scores of four are the neutral middle point.
