Abstract

Social anxiety disorder or SAD is a condition of abnormal anxiety experienced by individuals when they are facing a social situation. People with SAD usually tend to avoid social situations because they are afraid or anxious of getting a negative evaluation from other people. The negative impact for people with SAD is important for the need for measuring instruments that can detect the symptoms. The lack of SAD measurement tools in Indonesia is the reason why this validation study (SPIN) is important. The Social Phobia Inventory or SPIN is a self-report measurement tool for SAD symptoms and has good both in reliability and validity in several countries. This study aims to prove the validity and reliability of SPIN in Indonesia with 118 participants. The participants include people with SAD and healthy people.
