Background: Beyond ability, traits related to perseverance, such as grit and self‐discipline, are associated with adaptive educational outcomes. Few studies have examined the independent effects of these traits on outcomes and the mechanisms involved. - Aims: This study estimated parameters of a process model in which grit‐perseverance of effort (grit‐effort) and consistency of interest (grit‐interest) dimensions and self‐discipline were independent predictors of students’ science grades. The effect of the grit‐effort on grades was expected to be mediated by students’ self‐reported effort on optional out‐of‐school science learning activities. - Sample: Secondary school students (N = 110) aged between 12 and 14 years. - Methods: The study adopted a correlational design with measures taken on three occasions. Students completed self‐report measures of grit and self‐discipline early in the semester and effort on optional out‐of‐school learning activities 5 weeks later. Students’ science grades were collected at the end of the semester. Data were analysed using Bayesian path analyses using non‐informative and informative priors derived from previous research. - Results: Consistent with predictions, we found effects of grit‐effort on science grades mediated by effort, and self‐discipline on grades. Contrary to predictions, we also found an effect of self‐discipline on grades mediated by effort. Zero was a credible value for direct effects of grit‐effort on grades, and grit‐interest on effort and grades. - Conclusions: Results suggest grit‐effort and self‐discipline relate to effort on educational activities linked to better grades. The direct effect of self‐discipline on grades suggests that it may be related to other activities that determine science attainment. ...

(Transaction Periodicals Consortium, Rutgers University, 2021)The aim of the present study was to test the validity of the Brief Self-Control Scale (BSCS; Tangney, Baumeister and Boone 2004) including its dimensional structure based on competing one- and two-factor models, discriminant ...
Self‐control and health‐related behaviour : The role of implicit self‐control, trait self‐control, and lay beliefs in self‐control Hagger, Martin S.; Gucciardi, Daniel F.; Turrell, Amelia S.; Hamilton, Kyra (John Wiley & Sons; The British Psychological Society, 2019)Objectives: We tested unique contribution of trait self‐control, implicit self‐control, and lay beliefs in self‐control beliefs to the prediction of health‐related behaviours. We also tested whether relations between trait ...
Trait Self-Control, Social Cognition Constructs, and Intentions : Correlational Evidence for Mediation and Moderation Effects in Diverse Health Behaviours Hagger, Martin; Hankonen, Nelli; Kangro, Eva-Maria; Lintunen, Taru; Pagaduan, Jeffrey; Polet, Juho; Ries, Francis; Hamilton, Kyra (Wiley, 2019)Background: We examined effects of trait self‐control, constructs from social cognition theories, and intentions on health behaviours. Trait self‐control was expected to predict health behaviour indirectly through theory ...
