Generally, self-assessment of accuracy in the cognitive domain produces overconfidence, whereas self-assessment of visual perceptual judgments results in under-confidence. Despite contrary empirical evidence, in models attempting to explain those phenomena, individual differences have often been disregarded. The authors report on 2 studies in which that shortcoming was addressed. In Experiment 1, participants (N = 520) completed a large number of cognitive-ability tests. Results indicated that individual differences provide a meaningful source of overconfidence and that a metacognitive trait might mediate that effect. In further analysis, there was only a relatively small correlation between test accuracy and confidence bias. In Experiment 2 (N = 107 participants), both perceptual and cognitive ability tests were included, along with measures of personality. Results again indicated the presence of a confidence factor that transcended the nature of the testing vehicle. Furthermore, a small relationship was found between that factor and some self-reported personality measures. Thus, personality traits and cognitive ability appeared to play only a small role in determining the accuracy of self-assessment. Collectively, the present results suggest that there are multiple causes of miscalibration, which current models of over- and underconfidence fail to encompass.

The impostor phenomenon is a pervasive psychological experience of perceived intellectual and professional fraudulence. It is not a diagnosable condition yet observed in clinical and normal populations. Increasingly, impostorism research has expanded beyond clinical and into applied settings. However, to date, a systematic review examining the methodological quality of impostorism measures used to conduct such research has yet to be carried out. This systematic review examines trait impostor phenomenon measures and evaluates their psychometric properties against a quality assessment framework. Systematic searches were carried out on six electronic databases, seeking original empirical studies examining the conceptualization, development, or validation of self-report impostor phenomenon scales. A subsequent review of reference lists also included two full-text dissertations. Predetermined inclusion and exclusion criteria were specified to select the final 18 studies in the review sample. Of the studies included, four measures of the impostor phenomenon were identified and their psychometric properties assessed against the quality appraisal tool—Clance Impostor Phenomenon Scale, Harvey Impostor Scale, Perceived Fraudulence Scale, and Leary Impostor Scale. The findings often highlighted that studies did not necessarily report poor psychometric properties; rather an absence of data and stringent assessment criteria resulted in lower methodological ratings. Recommendations for future research are made to address the conceptual clarification of the construct's dimensionality, to improve future study quality and to enable better discrimination between measures.

Tertiary study presents students with a number of pressures and challenges. Thus, mental resilience plays a key role in students’ well-being and performance. Resilience research has moved away from conceptualising resilience as atraitand towards studying resilience as aprocessby which resources protect against the negative impact of stressors to produce positive outcomes. However, there is a lack of research in the academic domain examining the mechanisms underlying this process. This study addressed this gap by examining a range of personal resilience resources and their interaction with coping responses to produce positive adaptation outcomes, in a sample of 306 undergraduate students. Firstly, individual differences in resilience were examined, whereby factor analysis resulted in self-report measures of resilience-related attributes converging onto an overarching factor. The extracted factor was then validated against markers of positive adaptation (mental well-being, university adjustment, and somatic health symptoms), and the mediating roles of coping strategies were investigated through structural equation modelling. The resilience resources factor directly predicted mental well-being and adjustment; and indirectly predicted adjustment and somatic health symptoms through support-seeking and avoidant coping, respectively. These findings have theoretical implications for how resilience is conceptualised, as well as practical implications for improving student well-being and adjustment through promoting social support and reducing disengaged and avoidant coping strategies.

Participation in high school sports had positive effects on many Grade 12 and postsecondary outcomes (e.g., school grades, coursework selection, homework, educational and occupational aspirations, self-esteem, university applications, subsequent college enrollment, and eventual educational attainment) after controlling background variables and parallel outcomes from Grades 8 and 10 in a large, nationally representative, 6-year longitudinal study. In contrast to Zero-Sum and Threshold Models, these positive effects generalized across academic and nonacademic outcomes, across the entire range of athletic participation levels, and across different subgroups of students (e.g., SES, gender, ethnicity, ability levels, educational aspirations). Sport participation is hypothesized to increase identification/commitment to school and school values which mediate the participation effects, particularly for narrowly defined academic outcomes not directly related to sport participation. Consistent with this Identification/Commitment Model, extramural sport, and to a lesser extent team sport, had more positive effects than intramural and individual sports.
