Psychometric evaluation of the PROMIS SD-SF-8b instrument in individuals experiencing vasomotor symptoms due to menopause

Table 4 Convergent validity: correlations between PROMIS SD-SF-8b total score and assessments of related constructs

Measure	PROMIS SD-SF-8b total score
PGI-S SD (N = 1019)	0.651
PROMIS SRI-SF-8a (N = 1019)	0.608
MENQOL (N = 1017)	0.380
WPAI activity impairment (N = 1016)	0.230
WPAI presenteeism (N = 621)	0.221
WPAI overall work productivity loss (N = 621)	0.219
Severity of VMS (N = 1019)	0.158
Frequency of VMS (N = 1019)	0.114
WPAI absenteeism (N = 622)	0.073
EQ VAS (N = 1016)	– 0.254

Spearman rank correlation coefficients are presented. For the PROMIS SRI-SF-8a instrument, only the total score is used for the correlation. For the MENQOL instrument, only the vasomotor subscale score is used for the correlation
