Syllabus: How Can We Compare Psychological Processes Across Cultures?
Compare recruitment, interviewing and response patterns before explaining the different factor results.
Why you’re reading it. Apply measurement reasoning to a large empirical case in which broader sampling changes the problem.
A question to consider. The responsibility scale performs differently online and in interviews. How would you separate who participated from how the questionnaire was administered?
Why this reading
A questionnaire’s familiar name does not ensure that its responses support the same interpretation in another setting. This study examines the Big Five’s measurement structure across large datasets and investigates how response patterns, interviewers, and administration conditions complicate comparisons.
Before you read
WEIRD refers to Western, educated, industrialized, rich, and democratic populations. A factor structure describes patterns of shared variation among items. Acquiescence is a tendency to agree with statements regardless of their content. The Big Five framework and a particular questionnaire intended to measure it are distinct objects of evaluation.
Read for
- Compare the face-to-face survey evidence with internet samples, including differences in who participates and how responses are obtained.
- Examine the proposed explanations for weak measurement structure and how directly each is tested.
- Separate evidence about questionnaire performance from claims about whether a population possesses particular traits.
Consider afterwards
- The same translated questionnaire behaves differently in interviews and online. What comparisons could distinguish administration effects from differences in who took part?
Editorial context
The findings challenge uncritical transfer of instruments, not the existence of personality differences outside Western populations. Country, education, recruitment, language, and mode of administration are not interchangeable explanations. The study does not directly test lifespan stability or establish that every Big Five measure fails outside Western settings. Its implications complement the broader question of comparable score meanings addressed by Putnick and Bornstein.
