Curiosity, a personality trait underlying behavioral tendencies related to knowledge acquisition, learning, and thinking, can be expected to be of high relevance in the world of work. There is, however, to date no work-related curiosity measure. The present article reports results regarding the development and validation of the new 10-item Work-Related Curiosity Scale. Based on two studies, the measure had a one-factor solution, acceptable internal consistency, and expected construct validity. In Study 2, incremental criterion-related validities were found over and above five general curiosity scales (ΔR2 between .12 and .15), which is in line with the frame-of-reference approach underlying the development of the scale. Interestingly, the lack of evidence for criterion-related validity in Study 1 indicates that these results do not generalize across positions.

Personality changes throughout the life course and change is often caused by environmental influences, such as critical life events. In the present study, we investigate personality trait development in emerging adulthood as a result of experiencing two major life events: graduating from school and moving away from home. Thereby, we examined the occurrence of the two life events per se and the subjective perception of the critical life event in terms of valence. In addition, we postulate a moderation effect of the construct of mindset, which emphasizes that beliefs over the malleability of global attributes can be seen as predictors of resilience to challenges. This suggests that mindset acts as a buffer for these two distinct events. In a large longitudinal sample of 1,243 people entering adulthood, we applied latent structural equation modeling to assess mean-level changes in the Big Five, the influence of life events per se, the subjective perception of life events, and a moderating role of mindset. In line with maturity processes, results showed significant mean-level changes in all Big Five traits. While no changes in the Big Five dimensions were noted when the mere occurrence of an event is assessed, results indicated a greater increase in extraversion and diminished increase in emotional stability when we accounted for the individual's (positive/negative) perception of the critical life event. In case of extraversion, this also holds true for the moderator mindset. Our findings contribute valuable insights into the relevance of subjective appraisals to life events and the importance of underlying processes to these events.

Abstract. Conventional self-report measures are prone to response biases, which distort measurement in any applied assessment. The forced-choice (FC) format was proposed as a potential remedy for these biases. The purpose of these studies was to develop and evaluate a FC questionnaire for the occupational context based on the five factor model of personality. A single-stimulus Likert questionnaire was contextualized for occupational settings and psychometrically optimized in Study 1 ( N = 401). Considering optimal design strategies, we subsequently used this questionnaire to construct and validate a FC questionnaire in Study 2 ( N = 517). Methodological add-ons to established approaches were applied to achieve decent confirmatory model fit. The new questionnaire shows good psychometric qualities and strong validity. We make suggestions for further applications and studies.
