The Italian Validation of Singelis’s Self-Construal Scale (SCS): a Short 10-Item Version Shows Improved Psychometric Properties

Abstract

This study validates an Italian version of Singelis’s Independent and Interdependent Self-Construal Scale (SCS; Singelis in Personality and Social Psychology Bulletin, 20, 580–591, 1994; Singelis et al. in Cross-Cultural Research, 29, 240–275, 1995), a scale intended to measure individuals' feelings of connectedness to and separateness from social situations. Results of the Italian validation, carried out through three studies involved a total of 803 Italian university students, has led to a short 10-item version, with two 5-item orthogonal factors respectively reflecting independent self-construal and interdependent self-construal. The new short version of Singelis’s scale, as examined through exploratory and confirmatory factorial analyses, shows a more stable factor structure than the original version, maintaining the same internal consistency and obtaining improved indexes of concurrent validity for the Interdependent Self-Construal Scale, as explored by investigating the relationships with self-esteem.
