- The Sexual Interest, Activity and Satisfaction (SIAS) & Sexual Activity and Satisfaction (SAS) Scales are Both tools investigate the sexual activity and satisfaction of individuals with SCI.
- SIAS covers 3 domains: 1) sexual desire, 2) sexual activity, and 3) sexual satisfaction.
- SAS covers 2 domains: 1) sexual activity and 2) sexual satisfaction.
Clinical Considerations
- Detailed explanation of the purpose of the scale modification is not provided in the literature.
- This tool is one of the better-researched measures within the area of sexual interest and satisfaction: There is strong psychometric support for the scales. However, the items may contain content that is culturally sensitive.
- Both of these tools may be clinically useful to assist in understanding, describing and quantifying the sexual activity and satisfaction of individuals with SCI (both tetra and paraplegia).
- Ultimately, these tools may also be effective in evaluating the effectiveness of sex specific interventions.
ICF Domain
Body Function ▶ Functions of the Reproductive System
Administration
Both scales are self-report but may be administered in interview format if required.
Number of Items
- SIAS – 6 items
- SAS – 3 items
Equipment
None
Scoring
- Item are scored from 1-3 to 1-8.
- Higher scores indicate greater sexual activity and satisfaction.
- Total score is the sum of all item scores.
- SIAS total ranges 6-28, while SAS total ranges 3-16.
Languages
English
Training Required
No additional training required.
Availability
- The SAS measure can be found here.
- The SIAS can be found in the appendix of the following articles: https://pubmed.ncbi.nlm.nih.gov/7885719/ and https://pubmed.ncbi.nlm.nih.gov/8022632/
# of studies reporting psychometric properties: 3
Interpretability
MCID: not established in SCI
SEM: not established in SCI
MDC: not established in SCI
- Higher scores indicate greater sexual activity and satisfaction.
- No normative data for the SCI population has been reported at this time.
- Published data for the SCI population is available for comparison (see Interpretability section of the Research Summary sheet).
Reliability
Internal consistency is moderate for the SAS scale (Cronbach’s a = 0.87) as well as for the SIAS scale (Cronbach’s a = 0.86).
(Kreuter et al. 1994a; Kreuter et al. 1996)
Validity
Correlation of the SIAS and SAS is significant and:
- High with the Sexual Behaviour Scale (SBS):
(Pearson’s r = 0.82-85). - Moderate with the Emotional Quality of the Relationship (EQR) Scale:
(Pearson’s r = 0.55-0.57). - Moderate with the Hospital Anxiety and Depression Scale (HADS):
(SAS Pearson’s r = 0.49). - Moderate with Quality o Life (VAS):
(SAS Pearson’s r = 0.39).
(Kreuter et al. 1994a; Kreuter et al. 1996)
Responsiveness
No values were reported for the responsiveness of the SIAS or SAS for the SCI population.
Floor/Ceiling Effect
No values were reported for the presence of floor/ceiling effects in the SIAS or SAS for the SCI population.
