WHAT THE TEST MEASURES

About This Assessment

Social Interest Scale (SIS) Test

prosociality

This self-report measure is designed to assess an individual’s orientation toward social engagement, contribution to others, and perceived belonging. The Social Interest Scale (SIS) provides a brief indicator of social interest as a personality-related construct, and may be used in clinical or research settings as part of a broader assessment battery.

Developed by Crandall, J., it consists of 24 items and typically requires about 5 minutes to complete. The Social Interest Scale (SIS) is intended to support cautious interpretation in context of other clinical information, particularly when local translation or adaptation details are limited.
