This study aimed to examine the associations between the three dimensions of perfectionism—self-oriented, other-oriented, and socially prescribed perfectionism—and the four-factor structure of interpersonal manipulation strategies. A questionnaire survey was conducted with 347 Japanese adults aged 18 years and older. The three dimensions of perfectionism showed distinct patterns of association with interpersonal manipulation strategies. Other-oriented perfectionism showed significant positive associations with all manipulation factors, whereas socially prescribed perfectionism was positively associated only with the two behavioral manipulation strategies. In contrast, self-oriented perfectionism was negatively associated with three manipulation subfactors. These findings suggest that, despite sharing a common foundation in the pursuit of perfection, the three dimensions differ in their interpersonal characteristics.

This study examined whether agreeableness moderates the relationship between three work engagement facets (vigor, dedication, and absorption) and job satisfaction. Data were obtained from 878 Japanese employees. Hierarchical multiple regression analyses showed that vigor and dedication were positively associated with job satisfaction, whereas absorption was negatively associated. Although agreeableness showed no main effect, an interaction emerged between vigor and agreeableness. Simple slope analyses indicated that vigor was positively related to job satisfaction only among individuals high in agreeableness. These findings suggest that associations between work engagement and job satisfaction differ across engagement facets and are conditionally shaped by personality characteristics.

This study examined the association between cognitive traits and choice behavior on a user interface using visually interfering dark patterns. A web-based survey of 94 university students was analyzed. A fictitious video-streaming registration screen emphasized paid plans and made the free plan less noticeable. Logistic regression analysis showed that only CFQ scores were significantly associated with plan choice, with higher scores predicting selection of the free plan. Choice behavior under such dark patterns may thus reflect searching-and-checking strategies in attention-demanding situations.

Uncertainty tolerance, referring to the tendency to appraise uncertain situations as challenging rather than threatening, is relevant to various adaptive outcomes. Dalbert’s (2002) Uncertainty Tolerance Scale (UTS) was translated into Japanese and administered to 700 adults. Confirmatory factor analysis did not support the original eight-item one-factor structure, as reverse-worded items loaded on a separate factor. A modified five-item model showed acceptable fit and reliability, and its associations with related measures were generally consistent with expectations, though further validation is warranted.
