Postigo Á, Álvarez-Gutiérrez FJ, Cuesta M, García-Cueto E. General versus domain-specific grit in the work context. Scand J Psychol 2024. [PMID: 38701005 DOI: 10.1111/sjop.13025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 01/30/2024] [Accepted: 04/14/2024] [Indexed: 05/05/2024]
Abstract
Researchers have questioned whether grit should be conceptualized and measured as a global (i.e., domain-general) or domain-specific construct. Although evidence is beginning to appear that grit in educational and sport contexts may be measured as domain-specific, it has not yet been explored in the organizational context. The objective of this research was to study the psychometric properties of grit as domain-specific for subsequently analyzing if such domain-specific grit (labor grit) improves the predictive validity of different organizational results. A sample of 326 active workers was used (Myears = 37.52; SD = 9.85). Their grit levels in the general domain and specific domain were evaluated, as well as their main personality traits and other organizational results such as work engagement and work performance. The grit instrument as domain-specific showed excellent reliability (ω = 0.92), and the unidimensionality of the instrument was confirmed. The results point to the fact that giving an organizational connotation to the grit items does not improve the predictability of the results. However, labor grit adds incremental validity over personality traits and work engagement to predict task and contextual performance (Δr2 = 0.13), but not to predict counterproductive behavior.

Abstract
OBJECTIVE Though we all age, some age more successfully than others. Health and social connections have been identified as cornerstones to successful aging, yet the contributions from psychological factors are less clear. Our goal was to examine the influence of grit and growth mindset in successful aging in middle and older age. We also assessed whether grit or growth mindset mediated the lifestyle-successful aging relationship. METHOD We used a telephone questionnaire to measure grit and growth mindset, successful aging, and lifestyle for 263 adults, ages 40-80 years. RESULTS Higher grit-effort and growth mindset predicted more successful aging in younger (40-64 years) and older groups (65-80 years). Additionally, exercise frequency predicted successful aging for the combined sample and partially mediated the relationship between growth mindset and successful aging. CONCLUSIONS Our findings reveal grit-effort and a growth mindset as important contributors to successful aging in middle and older adulthood. Because psychological constructs are malleable, continued study of grit and growth mindsets is essential to enable their eventual application in changing the aging process.

Abstract
The syndrome of apathy has generated increasing interest in recent years as systematic evaluations have revealed its high prevalence and strong negative impact on quality of life across a wide range of neurological and psychiatric conditions. However, although several theoretical models have been proposed to account for various aspects of the condition, understanding of this syndrome is still incomplete. One influential model has proposed that apathy might be described as a quantitative reduction of goal-directed behaviour in comparison to an individual's prior level of functioning. Persistence of activity defined as the capacity to continue with a task - sometimes in the face of setbacks, high levels of difficulty or fatigue - is a crucial but understudied aspect of goal-directed behaviour. Surprisingly, it has not been investigated yet in the context of apathy. Here, we provide an overview of theoretical and experimental aspects of persistence in effort that might assist to develop methods for the investigation of persistence in human behaviour, particularly within the pathologic context of apathy.

Abstract
The current study adopted a person-centered approach to identify distinctive university students' profiles based on three variables (i.e., three academic motivations, grit, and self-control), regress multiple covariates (i.e., gender, age, study level, and college) on profile membership, and estimate differences on ambiguity tolerance across the estimated profiles. Data on 525 university students were modeled using Latent Profile Analysis. The findings found three latent profiles, which were: [1] Unmotivated and undisciplined students with low grit, [2] Moderately motivated and disciplined students with average grit, and [3] Highly motivated, gritty and disciplined students. Gender, study level, and college significantly predicted profile affiliation, identifying the characteristics of students within each profile. Significant differences were revealed in the ambiguity tolerance among the obtained profiles. These valuable results offer customized recommendations and prospective initiatives, strengthening the constructive effect of proper academic motivation types, purposeful grit, and intentional self-control (143 words).

Abstract
Background By combining the classical twin design with regression analysis, we investigated the role of two non-cognitive factors, self-control and grit, in the prediction of school performance. We did so at the phenotypic, genetic, and environmental level. Methods Teachers filled out a survey on the twins' school performance (school grades for reading, literacy, and math), self-control (ASEBA self-control scale), and grit (the perseverance aspect) for 4891 Dutch 12-years-old twin pairs (3837 pairs with data for both and 1054 pairs with data for one of the twins). We employed regression analyses to first assess the contributions of self-control and grit to school performance at the phenotypic level, and next at the genetic and environmental level, while correcting for rater (teacher) effects, parental SES, and sex. Results Higher SES was associated with better school performance, self-control, and grit. On average, girls had more self-control and grit than boys. Corrected for sex, SES, and teacher rater effects, genetic factors accounted for 74%, 69%, and 58% of the phenotypic variance of school performance, self-control, and grit, respectively. Phenotypically, self-control and grit explained 28.3% of the variance in school performance. We found that this phenotypic result largely reflected genetic influences. Conclusions Children who have better self-control and are grittier tend to do better in school. Individual differences in these three traits are not correlated because of shared environmental influences, but mainly because of shared genetic factors.

Abstract
OBJECTIVE Self-control is a meaningful predictor of crucial life outcomes. Knowingly, genes contribute substantially to differences in self-control, but behavioral genetic findings are often misinterpreted regarding environmental influences. Therefore, we reinvestigate the heritability of self-control as well as potential environmental influences, namely parenting and a chaotic home environment. METHOD We used cross-sectional and longitudinal data from the German twin family study TwinLife (N = 3354 individuals), structured in a multicohort design in which 13-, 19-, and 25-year-old twins rated their self-control, parents' behavior, and home environment. RESULTS Results showed increasing mean levels and 1-year stabilities for self-control accompanied by substantial genetic influences, increasing particularly from ages 19 to 25 (53% to 76%). While chaotic home environments and negative parenting were phenotypically associated with lower self-control, twin difference models revealed that differences in these individually perceived "environments" directly predicted self-control differences (β = -0.16 to -0.28) within families when controlling for genetic and environmental similarities. CONCLUSIONS In addition to the genetic anchoring of self-control, results indicate that environmental factors such as negative family environments are meaningful and depend on individual perceptions within families. Interventions for enhancing self-control should, therefore, rely on individual perspectives rather than objective characteristics of home environments.

Abstract
Despite government mandates to wear face masks in some public locations, why do some people still refuse to wear a face mask in public? This paper examines the relationship between grit, COVID-19 preventative health measure, and distress. Further, the mediating role of COVID-19 autonomous and controlled motivation is also investigated. The results suggest that grit is directly related to decreased distress and increased preventative behaviors. COVID-19 autonomous and controlled motivated mediated the relationship between grit, distress and preventive behaviors, such that COVID-19 autonomous motivation mediated the association between grit and preventive behaviors; while COVID-19 controlled motivation mediated the relationship between grit and psychological distress. These findings suggest that grit can be an important growth mindset in increasing preventative behaviors and individual well-being during the pandemic. Implications for human resource managers in attempting to help employees cope effectively during the pandemic are discussed.

Abstract
This study evaluated the factor structure, measurement invariance, criterion-related and incremental validity of the Chinese version of the Academic Grit Scale (AGS) among 723 adolescents from mainland China. Results of exploratory and confirmatory factor analyses supported the single-factor model, exhibiting scalar invariance across gender and partial scalar invariance across groups (i.e., middle and high school students). The AGS total score showed internal consistency and temporal stability when used one month later. Moreover, academic grit was shown to be positively correlated with academic achievement, general grit, and dimensional student engagement. Academic grit also predicted academic achievement after isolating the effects of the related variables (i.e., general grit and student engagement) and overlapping components of academic grit and the related variables. Overall, the Chinese version of the AGS demonstrated adequate reliability and validity and was shown to be a useful tool for examining academic grit in Chinese adolescents.

Abstract
Although grit is predictive of wellbeing, educational achievement, and success in life, it has been conceptualized as largely distinct from cognitive ability. The present study investigated the link between grit and executive functions since regulation abilities might underlie the expression of grit. A hundred thirty-four people were administered personality questionnaires (grit, impulsiveness, and mindfulness) and four experimental tasks tapping into Miyake's and Braver's models of executive functioning (including measures of flexibility, inhibition, working memory, and control mode dimensions). Multivariate analyses showed that two composite scores (trait and executive functioning) were reliably predictive of grit, although it was the trait composite (characterized by low impulsivity and high mindfulness) that explained more variance. Importantly, gritty participants did not demonstrate enhanced executive functioning. Instead, they exhibited a different pattern of performance that might be reflecting a cautious profile of control, characterized by paying attention to all available information, less reliance on previous contextual cues but sensitive to conflicting information of the current context. These findings converge with Duckworth's idea that high grit people do not necessarily have a greater cognitive capacity. Rather, they use it in a different way.

Abstract
Self-regulation has been studied across levels of analysis; however, little attention has been paid to the extent to which self-report, neural, and behavioral indices predict goal pursuit in real-life. We use a mixed-method approach (N = 201) to triangulate evidence among established measures of different aspects of self-regulation to predict both the process of goal pursuit using experience sampling, as well as longer-term goal progress at 1, 3, and 6-month follow-ups. While self-reported trait self-control predicts goal attainment months later, we observe a null relationship between longitudinal goal attainment and ERPs associated with performance-monitoring and reactivity to positive/rewarding stimuli. Despite evidence that these ERPs are reliable and trait-like, and despite theorizing that suggests otherwise, our findings suggest that these ERPs are not meaningfully associated with everyday goal attainment. These findings challenge the ecological validity of brain measures thought to assess aspects of self-regulation. Self-regulation helps people to achieve their goals, and has been studied across modalities. Here, the authors present longitudinal evidence suggesting that common neural and behavioral measures of self-regulation derived from laboratory tasks do not predict everyday goal pursuit.

Abstract
This review made a critical attempt to examine the studies on the role of English as a foreign language (EFL) learners' academic motivation and growth mindsets in their grit. Some investigations have been done on the role of academic motivation in learner grit. However, a significant positive correlation between academic motivation and grit has been approved in related studies. The related literature review justified the results by broaden-and-build and expectancy-value theories. The related literature has shown that grittier learners persist in doing tasks, and developing their intrinsic motivation. Furthermore, the related literature has approved the effect of learners' language mindset on their grit. In other words, learners with a growth mindset are persistent, and they devote their time to their performance. Finally, the pedagogical implications are expanded to promote the quality of language learning. This review also provides some suggestions for further research to illuminate our perspectives over motivation, mindset, and their interactions with each other.

Abstract
While scientific interest in understanding the grit trait has grown exponentially in recent years, one important gap in the grit literature relates to its biological and neural substrate. In the present study, we adopted a hypotheses-driven approach in a large sample of young adults (N = 120) with diverse educational backgrounds and work experiences in order to investigate the electrophysiological correlates of grit both during rest and while performing a learning task. Additionally, we selected a measure of impulsiveness to better understand the neural similarities and differences between grit and related self-control constructs. Based on previous work that implicated the prefrontal cortex in grit, we hypothesized that high grit participants would have lower frontal theta/beta ratio (a broadly used index that reflects prefrontally-mediated top-down processes, which might indicate better control over subcortical information). Furthermore, we expected the perseverance of effort facet of grit to be linked to higher complexity during task engagement because previous research has shown complexity indexes (entropy and fractal dimension) to be linked to effort while performing cognitive tasks. Our results revealed that although there were no differences at rest as a function of grit, the participants with high grit and high consistency of interest scores exhibited lower frontal theta/beta ratios during the learning task. This pattern suggests that individual differences in grit might be more evident when top-down control processes are at work. Furthermore, there was a positive association between perseverance of effort and entropy at task, which might indicate more effort and engagement in the task. Finally, no association was found between the neural indexes (frontal theta/beta ratio, entropy, or fractal dimension) and impulsiveness, neither impulsiveness mediated between grit and brain measures. Finally, when controlling for impulsiveness and demographic variables (gender, age, education, and work experience) the effects at the facet level remained statistically significant. While there is still a long way to fully understand the neural mechanisms of grit, the present work constitutes a step toward unveiling the electrophysiological prints of grit.

Abstract
Suicide research is vitally important, yet-like psychology research more broadly-faces methodological challenges. In recent years, researchers have raised concerns about standard practices in psychological research, concerns that apply to suicide research and raise questions about its robustness and validity. In the present paper, we review these concerns and the corresponding solutions put forth by the "open science" community. These include using open science platforms, pre-registering studies, ensuring reproducible analyses, using high-powered studies, ensuring open access to research materials and products, and conducting replication studies. We build upon existing guides, address specific obstacles faced by suicide researchers, and offer a clear set of recommended practices for suicide researchers. In particular, we consider challenges that suicide researchers may face in seeking to adopt "open science" practices (e.g., prioritizing large samples) and suggest possible strategies that the field may use in order to ensure robust and transparent research, despite these challenges.

Abstract
The current study examined the longitudinal measurement invariance (LMI) of the Short Grit Scale (Grit-S) in a survey sample of Chinese young adults (N = 233, 48.9% male, mean age = 19.36 years, SD = 0.90 years) who completed the Grit-S twice over a 3-month interval. Confirmatory factor analysis was conducted to examine the LMI of the Grit-S across time. Results showed that the Grit-S has strict longitudinal invariance (i.e., equality of factor patterns, factor loadings, item intercepts, and item uniqueness for all items) over time. Additionally, the internal consistency indices of the Grit-S were acceptable across time, the stability coefficients over time were moderate, and latent factor means did not differ significantly across time. In sum, these findings suggest that the Grit-S has satisfactory longitudinal properties when used in Chinese young adults.
