Sickness Impact Profile (SIP)
Description: A generic health status measure of change in behaviour as a consequence of illness health-related quality of life (QoL).
Format: 136 items describing activities of daily living (ADL), divided into 12 categories: sleep and rest, eating, work, home management, recreation and pastimes, ambulation, mobility, body care and movement, social interaction, alertness behaviour, emotional behaviour, and communication. Patients endorse statements that best describe them that day and are related to their health.
A shorter version of the SIP containing 68 items also is available.
Scoring: Endorsed items are scored on a numeric scale, with higher scores reflecting greater dysfunction. In addition to individual category scores, an aggregate psychosocial score can be derived from four categories, and an aggregate physical score is calculated from three categories.
Administration and Burden: Interviewer-administered; Self-administered. Approximately 20-30 minutes for the SIP; Approximately 15-20 minutes for the SIP 68.
Psychometrics for SCI: There is published data and norms available for a SCI population, as well as for individuals with other disabilities for the SIP 68 . However, the evidence on the psychometric properties of the SIP and SIP 68 for a SCI population is limited and more research is needed to assess reliability and responsiveness.
Languages: The SIP has been translated into several languages.
QoL Concept: The SIP is a Health-Related QoL measure of independence in performing Activities of Daily Living, which corresponds to Boxes B (societal standards and priorities) and C (achievements; activities of daily living) of Dijker’s Model.
