Test-Retest Reliability
- Overall test-retest reliability coefficients were high for each domain of the IV-FSFI (r ranging from 0.73 to 0.86) (Fakhri et al., 2012)
- Test-retest correlation coefficients over 2-4 weeks were 0.84 (p < 0.05) for the total scale, 0.68-0.83 for the subscales (Liu et al., 2016)
- FSFI-J showed high test-retest reliability (ICC > 0.78) (Takahashi et al., 2011)
- The test-retest procedure revealed that the concordance correlation coefficient was very high both for FSFI-I total score (Pearson’s P = 0.93) and for each domain (Pearson’s P always >0.92). (Filocamo et al., 2014)
- Test-retest reliability was good (r=0.86-0.93) for all domains in the whole sample. (Ryding et al., 2015)
Internal Consistency
- Internal consistencies within the acceptable range (α ranging from 0.72 to 0.90) (Fakhri et al., 2012)
- FSFI-J showed high internal consistency (Cronbach’s α > 0.84) (Takahashi et al., 2011)
Reliability
- Cronbach’s α coefficient for various domains was sufficiently high ranging from 0.84 to 0.97 (Rehman et al., 2015)
- Cronbach values were 0.94 for the total scale, 0.72-0.90 for the domains (Liu et al., 2016)
- Cronbach’s alpha coefficients for total and domain score were sufficiently high, ranging from 0.92 to 0.97 for the total sample. (Filocamo et al., 2014)
- Cronbach’s alpha was 0.90-0.96 (Ryding et al., 2015)
Correlation Coefficients
- Item-total correlation coefficients ranged between 0.47 and 0.83 (p < .05) (Liu et al., 2016)
- Correlations between all corresponding domains of the FSFI and the SFQ were high for the whole sample (r=0.74-0.87) and moderate to high for both the clinical and the control group. (Ryding et al., 2015)
Discriminant validity
- Discriminant validity was very good for each of the FSFI domains (P=0.001, t=7.05-15.58. (Ryding et al., 2015)
