Are Semantic Response Scales Equivalent?

Area of Science:

• Psychometrics
• Survey methodology
• Quantitative psychology

Background:

• Three common survey response formats exist: Likert, semantic-differential, and single-anchor (Stapel).
• Previous research suggested these formats are interchangeable in data collection.
• Understanding response format impact is crucial for survey validity.

Purpose of the Study:

• To compare the psychometric properties of Likert, semantic-differential, and Stapel response formats.
• To investigate whether these formats are truly interchangeable.
• To identify the most and least preferred response formats based on empirical data.

Main Methods:

• Analysis of covariance structures was employed.
• Four distinct datasets were utilized for robust analysis.
• Statistical comparisons were made across the three response formats.

Main Results:

• Evidence consistently contradicted the interchangeability of the response formats.
• The semantic-differential format emerged as the most preferred format across studies.
• The Stapel format was consistently the least preferred format in most analyses.

Conclusions:

• Survey response formats are not interchangeable and have differential preference.
• The semantic-differential format offers superior user preference and potentially better data quality.
• Researchers should carefully consider response format selection in survey design to optimize results.
