Grit Scale

 Scoring:

• Range: 12-60 (12 items, 1-5 each).


• Reverse-scored items (2, 3, 5, 7, 8, 11): These reflect lack of consistency, so "Very much like me" (5) becomes 1, "Not like me at all" (1) becomes 5, via (6 - value).


• Non-reversed items (1, 4, 6, 9, 10, 12): Scored as is (1-5).


• Total score is summed, then averaged (1-5 scale).


• Subscales:
  
  • Perseverance of Effort (6 items, 6-30, avg 1-5).
  
  
  • Consistency of Interest (6 items, 6-30, avg 1-5, reverse-scored).
  
  

Interpretation:

• ≤2.5: Low grit


• 2.6-3.5: Moderate grit



• 3.5: High grit These are approximate cutoffs based on Duckworth’s research (e.g., mean ~3.65 in adults, Duckworth et al., 2007), adjusted for simplicity.

Verification:

• All "Not like me at all" (1): Perseverance = 6 × 1 = 6, Consistency = 6 × (6-1) = 30, Total = 36, Avg = 3 (Moderate).


• All "Very much like me" (5): Perseverance = 6 × 5 = 30, Consistency = 6 × (6-5) = 6, Total = 36, Avg = 3 (Moderate).


• All "Somewhat like me" (3): Perseverance = 6 × 3 = 18, Consistency = 6 × (6-3) = 18, Total = 36, Avg = 3 (Moderate). The symmetry reflects the balanced subscales.
