- Measures sexual adjustment after SCI.
- Designed to assess different aspects of sexuality before and after injury.
- Has 2 domains: interest in sexuality and sexual satisfaction.
Body Function – Subcategory: Functions of the Reproductive System
Number of Items:
Brief Instructions for Administration & Scoring
- Self-administered then checked by personal interview.
- Four items determine the impact SCI had on sexuality and sexual function using a 4-point response scale (increased=3, unchanged=2, decreased=1, and absent=0). The remaining 2 questions assess general satisfaction after injury and the difference between satisfaction post- and pre-injury, using a modified 7-point visual analogue scale (ranging from very dissatisfied (1) to very satisfied (7)).
- The scores for the 2 satisfaction items are rescaled to a range of 0 to 3 in order to enable calculation of a composite score.
- The composite score is a sum of 6 items and has a maximum value of 18 and a minimum value of 0.
- Achieving a high score on the SIS illustrates greater sexual adjustment while a lower scorer demonstrates poor sexual adjustments after SCI.
- There are no known cut points or norms for the SCI population to assist with interpretation.
Only English so far.
None but knowledge about sexuality is helpful.
See the how-to page of this tool.
- The SIS provides a reasonably well-defined spinal cord specific measure that may be useful in eliciting information regarding a sensitive area.
- Although it has not been widely used and psychometric properties have been reported by only one study, it is one of few sexuality scales that have been used within the SCI population.
- The type of SCI needs to be taken into consideration when interpreting the results. Sexual adjustment for those with incomplete injuries may differ considerably when compared to complete injuries. Items should be acceptable to both males and females though items may seem personal and embarrassing to some.
- The SIS was developed for use in the SCI population. It provides a quick review of the individual’s sexual experiences, while factoring in their pre-injury state.
Measurement Property Summary
# of studies reporting psychometric properties: 1
- Internal consistency of the SIS is high (Cronbach’s a=0.96).
[Siosteen et al. 1990]
- The SIS is high correlated with age at injury (Pearson’s r=0.63) and Quality of Life (QL-VAS method) – Dysfunction rating (Pearson’s r=-0.61) and moderate with Total QL rating (Pearson’s r=0.52), QL-Loss of independence (Pearson’s r=-0.49) and QL-Depression (Pearson’s r=-0.45).
[Siosteen et al. 1990]
No values were reported for the responsiveness of the SIS scale for the SCI population.
No values were reported for the presence of floor/ceiling effects in the SIS for the SCI population.
