Quality-of-life instruments in hypertension.

This review considers the choice of dimensions to be assessed and the practical problems of measuring quality of life in hypertensive patients. The dimensions of symptomatic well-being, psychological well-being, sleep, sexual function and cognitive function should be assessed. Symptomatic well-being may be measured by many different instruments, and that devised by the authors has been used extensively. The results in different trials may therefore be examined for consistency and sensitivity. Psychological well-being has been assessed by the Psychological General Well-Being Index, the Symptom Rating Test and the Profile of Mood States. The response of these instruments is discussed. The assessment of sleep, sexual function and cognitive function is also described. It is recommended that quality-of-life instruments to be employed in trials of antihypertensive drugs are known to be sensitive to the effects of such drugs.
