The SSS-18.3 measure offers special focus on physical health and illness prevention services. SSS measures two distinct satisfaction factors as well as global service satisfaction. The item response strategy of the SSS yields broader score distributions with increased sensitivity and predictive power.

The SSS measures have broad applicability to human services with special focus on physical health and prevention services. The SSS versions measure multiple factors within the “service satisfaction construct”: “Provider Manner and Skill” and “Perceived Outcome of Care”. The “SSS versions” typically yield broader score distributions that are associated with increased sensitivity of measurement and predictive power. The SSS versions use a 5-point “Delighted” to “Terrible” item response scale that also contributes to enhanced sensitivity and more normalized score distributions. The SSS-30 is available in a short form: The SSS-16. A third version of the SSS-30 is an adaptation for use in residential care: The SSS-RES. A fourth version, the SSS-18.3 is a version of the SSS that includes capture of demographic variables and items measuring life satisfaction, current health status, and evaluation of service effectiveness. Psychometric properties, operating characteristics, and coefficient alpha are very strong for these measures.
