Development and validation of the Stephenson Multigroup Acculturation Scale (SMAS)

Area of Science:

• Psychology
• Sociology
• Cross-cultural research

Background:

• Acculturation is a complex process influencing individuals from ethnic minority groups.
• Existing measures may not adequately capture the multidimensional nature of acculturation across diverse populations.
• A robust and validated scale is needed to assess acculturation experiences.

Purpose of the Study:

• To develop and psychometrically evaluate the Stephenson Multigroup Acculturation Scale (SMAS).
• To examine the factor structure, reliability, and validity of the SMAS across multiple ethnic groups.
• To establish SMAS as a reliable tool for acculturation research.

Main Methods:

• The development involved three studies with 436 participants from 5 ethnic groups.
• Exploratory and confirmatory factor analyses were used to determine the scale's structure.
• Psychometric properties, including reliability and validity, were rigorously assessed.

Main Results:

• Exploratory factor analysis identified a two-factor solution: ethnic society immersion and dominant society immersion.
• A refined 32-item version of the SMAS demonstrated a robust factor structure across diverse groups.
• Confirmatory factor analysis supported the proposed two-factor model, with high reliability and validity indexes.

Conclusions:

• The Stephenson Multigroup Acculturation Scale (SMAS) is a psychometrically sound instrument for measuring acculturation.
• The findings support acculturation as a mediator between ethnic group affiliation and assessment outcomes.
• SMAS provides a valuable tool for researchers studying diverse populations and acculturation processes.
