Sexual Interest, Activity and Satisfaction (SIAS) / Sexual Activity and Satisfaction (SAS) Scales

Download Clinical Summary PDF

Tool Description

  • 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.

ICF Domain:

Body Function – Subcategory: Functions of the Reproductive System

Number of Items:

SIAS - 6 items; SAS – 3 items

Brief Instructions for Administration & Scoring

Administration:

  • Both scales are self-report but may be administered in interview format if required.

Equipment:None.

Scoring:

  • The response items can be summed without weights or standardization.

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 Study Details sheet).

Languages:

Only English so far.

Training Required:

No special training is required to score or administer the scales.

Availability:

For the SAS measure, see the how-to page of this tool. The SIAS was not found.

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.

Measurement Property Summary

# of studies reporting psychometric properties: 3

Reliability:

  • Internal consistency is high 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 is significant and:
    • high with the Sexual Behaviour Scale (Pearson’s r=0.82-85)
    • moderate with the Emotional Quality of the Relationship Scale (Pearson’s r=0.55-0.57)
    • moderate with the Hospital Anxiety and Depression Scale (Pearson’s r=0.49).

[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.
