Table 1 The values of alpha and their interpretation
From: A framework for designing medical devices resilient to low-resource settings
Alpha | Internal Consistency |
|---|---|
α ≥ 0.9 | Excellent |
0.8 ≤ α < 0.9 | Good |
0.7 ≤ α < 0.8 | Acceptable |
0.6 ≤ α < 0.7 | Questionable |
0.5 ≤ α < 0.6 | Poor |
α ≤ 0.5 | Unacceptable |
