Sexual Interest and Satisfaction Scale

Last Updated


The Sexual Interest and Satisfaction Scale (SIS) measures sexual adjustment after Spinal Cord Injury (SCI). The SIS is designed to assess sexuality and sexual function before and after the injury in two domains: interest and satisfaction (Siösteen et al., 1990).

Acronym SIS

Area of Assessment

Life Participation
Patient Satisfaction
Quality of Life

Assessment Type

Patient Reported Outcomes

Administration Mode

Paper & Pencil




  • Brain Injury Recovery
  • Spinal Cord Injury

Key Descriptions

  • Number of items in the instrument: 6.
  • Minimum and Maximum score: 0-18.
  • Four items evaluate the impact of the injury on sexuality and sexual function using a 4-point response scale. The remaining 2 questions assess general satisfaction before and after injury using a modified 7-point visual analog scale. The post-injury rating is then converted to a 4-point scale, as is the difference between the pre- and post-injury ratings.
  • Administration Instructions: The SIS is a short self-administered questionnaire. It has been used in conjunction with other measures to gain a wider understanding of the client’s experience of sexuality (Siösteen et al., 1990).

ICF Domain

Body Function


The SIS focuses on individuals in relationships and thus does not assess independent sexual experiences or experimentation. In addition, it is unclear whether the tool has been used with non-heterosexual individuals. The concept of positive sexual adjustment is also not well defined, as it may entail abstinence for some people. This may alter the meaning of the data collected by the instrument (Abramson et al., 2008).


Total care of SCI patients should include sexual information and counseling to improve sexual adjustment after injury (Siösteen et al., 1990).

Spinal Injuries

back to Populations

Internal Consistency

Spinal Cord Injury: (Siösteen et al., 1990)

  • Excellent internal consistency; may indicate redundancy (Cronbach’s alpha = 0.96)

Construct Validity

Spinal Cord Injury: (Siösteen et al., 1990; n = 73, ages ranged between 16-72 years more than 1 year post injury)

  • Excellent correlation with age at injury (r=0.63)
  • Excellent correlation with Quality of Life Dysfunction rating (r=-0.61)
  • Adequate correlation with Total QL rating (r=0.52)
  • Adequate correlation with QL-Loss of independence (r=-0.49)
  • Adequate correlation with QL-Depression (r=-0.45)

Brain Injury

Internal Consistency

Traumatic Brain Injury (Kreuter et al., 1998)

  • Excellent internal consistency; may indicate redundancy (Cronbach’s alpha = 0.90)
