The reliability and validity of the brief measures of perceived childhood harshness and unpredictability: A revised Chinese version for emerging adults.

BACKGROUND

Childhood harshness and unpredictability significantly shape life history strategies, as well as downstream psychological and behavioral patterns. However, prior research involving Chinese populations has suffered from inconsistent metrics and limited measurement items.

OBJECTIVE

We adapted the English version of Maranges et al.'s (2022) Harshness and Unpredictability Scale in Childhood, translating it into Chinese and assessing its reliability and validity.

PARTICIPANTS AND SETTING

Six groups of different college student samples have been collected and the Chinese version of the Harshness and Unpredictability scales has been revised in two separate studies.

METHODS

We evaluated the factor structure using both exploratory and confirmatory factor analyses, determined internal consistency, item discrimination, concurrent validity, and assessed gender measurement invariance through multiple CFAs. The test-retest reliability was subsequently established by assessing participants after a designated interval.

RESULTS

Both scales passed psychometric tests, including exploratory and confirmatory factor analyses, and exhibited strong internal consistency and item discrimination. Gender invariance in the measurements was also confirmed.

CONCLUSIONS

The Chinese version of the Childhood Harshness and Unpredictability Scale demonstrates high reliability and validity, making it suitable for deeper examinations into the relationship between early environments and life history strategies in Chinese contexts.
