To grit or not to grit, that is the question!

The current study tested the validity of grit as a non-cognitive construct related to, yet distinct from self-control. Data were collected from N = 1907 adults spanning the life-course (53.1% female, M age = 41.4 years). Associations between grit and present and past goals were very similar to ones observed with self-control. Extensive model tests using structural equation modeling provided evidence of substantial overlap between these two constructs, calling into question the conceptual and empirical distinctiveness of grit vis-a-vis self-control, as well as the importance of grit as a unique and independent characteristic salient for the pursuit and achievement of long-term goals. This finding was consistent and invariant across adult developmental periods. Study implications for grit-investment are discussed. (C) 2018 The Authors. Published by Elsevier Inc.
