Female Sexual Function Index FSFI

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)

• The Female Sexual Function Index (FSFI) was developed to assess six domains of sexual function in women.
• The questionnaire consists of 19-items to measure sexual function concerning sexual desire, sexual arousal, lubrication, orgasm, satisfaction, and pain/discomfort.
• The FSFI was designed to assess sexual functioning of all women regardless of their ethnicity, age, educational background, economic status and sexual orientation.
• A problem occurring in any one of the 4 phases of the sexual response cycle (excitement, plateau, orgasm, and resolution) results in sexual dysfunction.
• The participant fills the FSFI survey with respect to the past 4 weeks of sexual activity.
• The FSFI is not suitable for assessing the sexual functioning of sexually inactive women.
• A score of less than 26.55 on the FSFI determines sexual dysfunction in the individual.
