Descriptive statistics, item-scale correlations, and internal consistency and test-retest reliability for the Day-to-Day Impact of Vaginal Aging scales

Domain scale	Number of items	Participant sample	Mean (±SD) score	Observed score range^a	Item-scale correlations	Cronbach’s alpha	Test-retest intraclass coefficients^b
Activities of daily living	5	745	0.3 (±0.5)	0 to 4	0.52 to 0.67	0.82	0.47
Emotional well-being	4	745	0.3 (±0.6)	0 to 4	0.68 to 0.74	0.86	0.67
Sexual functioning (short form) ^c	5	734	0.8 (±0.9)	0 to 4	0.52 to 0.81	0.87	0.58
Sexual functioning (longer form)^d	9	462	0.9 (±0.90)	0 to 4	0.57 to 0.86	0.94	0.57
Self-concept and body image	5	742	0.9 (±1.0)	0 to 4	0.71 to 0.82	0.91	0.72

. Possible range was 0 to 4 for all domain scales, with higher scores indicating greater impact. Domain scale scores were obtained by averaging the scores of all individual contributing items.

. Test-retest intraclass coefficients were obtained from repeat administration of measures after 1 to 2 weeks in a subset of 175 women drawn from all racial/ethnic groups represented in the parent cohort.

. The short, 5-item version of the sexual functioning domain scale was completed by all postmenopausal women who reported any vaginal symptoms, regardless of sexual activity status.

. The longer, 9-item version of the sexual functioning domain scale was completed only by symptomatic postmenopausal women who reported sexual activity in the past four weeks.
