Evidence of Technical Quality
Populations for which technical quality evidence has been collected

Four samples were used to collect technical quality evidence for the shorter (eight-item) form: two samples of West Point cadets, Scripps National Spelling Bee finalists, and Ivy League Undergraduates (Duckworth & Quinn, 2009).

Reliability evidence

Internal consistency was estimated separately across the four samples (mean Cronbach's alpha=0.78, min=0.73, max=0.83) (Duckworth & Quinn, 2009).

Validity evidence
Evidence based on content
Items were developed based on existing theoretical and empirical literature on grit and persistence and informed by expert review (Duckworth et al, 2007).
Evidence based on response processes
No information is available in the references reviewed.
Evidence based on internal structure
Exploratory and Confirmatory Factor Analysis techniques were used to substantiate a second-order factor model with two specific factors (consistency of interests and perseverance of effort) and a general grit factor (Duckworth et al., 2007; Duckworth & Quinn, 2009).
Evidence based on relations with other variables
The overall grit score accounted for an average of 4% of the variance in multiple measures of individual success, including educational attainment, academic achievement, and school retention. The overall grit score was not positively related with IQ but strongly related to a measure of conscientiousness as captured by a Big Five personality inventory (Duckworth et al., 2007).
