What was measured

The Sexual Adjustment Questionnaire (SAQ) is a 20-item questionnaire with an overall score range between 8 and 100 including the following domains: desire, ranging between 5 and 30; dysfunction, 0 and 25; activity, 0 and 10; satisfaction, 1 and 10; and fatigue, 1 and 5. The change in SAQ score is calculated by subtracting the baseline score from the follow-up score. A positive change indicates an improvement in sexual well-being.
