Calculate the mean scale score (arithmetic mean) of all items in the scale, keeping in mind that reverse coded items (those with an asterisk) first need to be reverse coded. Do not include asterisks when writing out question on survey. These are merely for your reference when analyzing the survey.
“We sought a brief, stand-alone measure of grit that met four criteria: evidence of psychometric soundness, face validity for adolescents and adults pursuing goals in a variety of domains (e.g., not just work or school), low likelihood of ceiling effects in high-achieving populations, and most important, a precise fit with the construct of grit.”

During validity testing, items loaded onto two, highly correlated factors: consistecy of interests and perseverance of effort. Items had high consistency with an alpha of 0.85 for the overall scale and 0.84 and 0.78 for consistency of interests and perseverance of effort, respectively.
