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.

The relationship between future self-continuity and intention to use Internet wealth management: The mediating role of tolerance of uncertainty and trait anxiety.

This study aimed to analyze the mediating effect of tolerance of uncertainty (TU) and trait anxiety (TA) on future self-continuity (FSC) and intention to use Internet wealth management (IUIWM) systems. A questionnaire survey was distributed online and a total of 388 participants completed questionnaire, The questionnaire included the following scales: Chinese version of the FSC, Intention to Use the Internet Wealth Management, TU, and TA. Pearson correlation was used to investigate the correlation coefficient between variables while the sequential regression method was used to analyze relationship between variables. To analyze the collected data, the SPSS 26.0 was used. A two-step procedure was applied to analyze the mediation effect. Confirmatory factor analysis (CFA) was conducted to test the measurement model. Afterward, the Maximum Likelihood method was used for path analysis, and the Bias-corrected Bootstrap method was used to investigate determine the estimated value and confidence interval of the mediating effect. To analyze the mediation effect, the Mplus 7.0 was used. The results showed that FSC positively predicted individuals' Internet wealth management systems. Furthermore, TU and TA played complete serial multiple mediating roles between FSC and IUIWM. The role of TA and TU have negative impact on intention to use. This study provides a theoretical basis in personality psychology that Internet financial product suppliers can use to improve the attractiveness of their products. Product managers can subdivide users according to these personality traits to provide customized products.

The Mediating Role of Chinese College Students' Control Strategies: Belief in a Just World and Life History Strategy.

The harshness and unpredictability of early life circumstances shape life history strategies for trade-offs between the resources devoted to somatic and reproductive efforts of individuals in the developmental process. This paper uses belief in a just world as a reflection of early environmental cues to predict an individual's life history strategies. Research has found that belief in a just world influences life history strategies through a sense of control. However, the relationship between a sense of control and a life history strategy is flawed because influencing life history strategies should be intrinsic to control strategies rather than a sense of control. A total of 408 Chinese undergraduate students completed the Personal Belief in a Just World Scale, Mini-K Scale, and Primary and Secondary Control Scale. Structural equation modeling suggested that belief in a just world can directly or indirectly influence life history strategies through primary and secondary control strategies, respectively; there was no statistical difference in the degree of influence between the two paths. These results deepen our understanding of the underlying mechanisms in the relationship between belief in a just world and life history strategies, which can be utilized to ensure a slow life history strategy among Chinese university students in the future.
