Psychometric Properties of the Grit-S in Chinese Nurses

Abstract

Grit, as a positive psychological trait, could affect the stability of nursing workforce and nurses’ physical and mental health continuously. The Short Grit Scale (Grit-S) with fewer items than the original Grit Scale was widely used to measure individual trait-level grit. However, the psychological properties of Grit-S among Chinese nurses have not been verified. A self-designed sociodemographic questionnaire was used to investigate 709 Chinese nurses in the study, and Grit-S, Big Five Inventory-44, Brief Self-Control Scale, 10-item Connor-Davidson resilience scale, and Task Performance Scale were adopted to collect information of grit, personality, self-control, resilience, and work performance. The confirmatory factor analysis, Pearson correlation analysis, hierarchical regression analysis, and multi-group confirmatory factor analysis were conducted to verify the psychometric properties of the Grit-S. The results demonstrated that the Grit-S had sound validity and reliability among Chinese nurse samples and had good measurement invariance across nurses in general hospitals and psychiatric hospitals. The results of this study provide confidence in using the grit measurement among Chinese nurse in the future.

“…For more recent work relating cluster algebras and tree-level amplitudes or loop integrals, see also [105,106] The quiver that arises by mutating 1245 of the initial cluster, where the effect of the mutation is described in eqs. (32) and (33) for the variable, and below eq. ( 34) for the arrows of the quiver.…”

“…Perhaps more importantly, a new qualitative feature starting at this multiplicity is the existence of pT r(4, n) rays which are inaccessible from the Gr(4, n) cluster algebra even when enlarging the latter so as to also include * As with the selection of cluster variables/rational letters, also the limit ray must coincide with a pT r(4, n) ray so as not to discard the associated square-root letters.

“…This observation may point towards the right formulation of the (extended) Steinmann relations at lower multiplicity n < 6, which is currently not well understood. § Further aspects of cluster-algebraic structures and their generalizations to Feynman integrals have been discussed in [238,27,33,138,34], and providing a first-principle derivation of their presence would be a very interesting goal for the future.…”

“…And as a proof of concept that the bootstrap may also work for phenomenologically relevant physical quantities, it has been used to rederive the three-loop soft anomalous dimension in quantum chromodynamics, up to an overall numerical factor [24]. Further areas expanding the realm of the bootstrap paradigm include amplitudes in simpler kinematics [25][26][27] and three-particle form factors in N = 4 SYM [28,29], as well as individual Feynman integrals [9,20,[30][31][32][33][34], or basis sets thereof [35,36].…”
