Grit, defined as perseverance of effort and consistency of interest, has attracted attention as a predictor of success in various fields beyond IQ and the Big Five personality dimension of Conscientiousness. The purpose of the current study was to examine previously uninvestigated questions regarding grit using a cross-sectional design among a large number of working adults in Japan. First, we tested geographical generalizability of associations between grit and orientations towards happiness by comparing previous studies in the U.S. and the current study in Japan. It was confirmed that orientation towards meaning rather than orientation towards engagement had a stronger positive correlation with grit in our sample of Japanese people. This result is inconsistent with previous studies in the U.S. Furthermore, the Big Five dimension of Openness to Experience was newly confirmed as having a positive association with grit. Second, we examined the association between grit and work engagement, which is considered as an outcome indicator for work performance. In this analysis, grit was a strong predictor for work performance as well as academic performance. [ABSTRACT FROM AUTHOR]

We examined the predictive validity of a segmentation strategy based on intention and cancer worry for mammography adoption and explored key factors for promoting mammography adoption in each segment. A questionnaire survey was completed by 641 women aged 40–59 years. Among them, 559 answered a follow-up survey after 15 months. They were categorized into five segments: maintenance group (S5), higher implementation intention group (S4), higher goal intention group (S3), higher worry group (S2), or lower worry group (S1). The odds of participants in each segment adopting mammography during the follow-up period were calculated. Logistic regression analysis was conducted to identify psychological predictors (five attitudes to mammography and perceived health competence) of transition to upper segments (S1 vs. S2, S2 vs. S3, S3 vs. S4, S4 vs. S5). Compared to S5, other segments did not undertake mammography at significant rates during the follow-up. The following were significant predictors for inclusion in upper segments: Lack of importance and perceived health competence were associated with inclusion in S2; lack of importance and barriers to screening were associated with inclusion in S3; perceived health competence was associated with inclusion in S4; and lack of importance was associated with inclusion in S5. These results confirm the predictive validity of a segmentation strategy, and indicate that there might be specific key factors for each segment in promoting mammography adoption.
