Generalised Anxiety Disorder Assessment (GAD-7) |
The GAD-7 score is calculated by assigning scores of 0, 1, 2, and 3, to the response categories of 'not at all', 'several days', 'more than half the days', and 'nearly every day', respectively, and adding together the scores for the seven questions. Scores of 5, 10, and 15 are taken as the cut-off points for mild, moderate and severe anxiety, respectively. When used as a screening tool, further evaluation is recommended when the score is 10 or greater. Using the threshold score of 10, the GAD-7 has a sensitivity of 89% and a specificity of 82% for GAD. |

Beck Depression Inventory-Second Edition (BDI-II) |
The BDI-II is a widely used 21-item self-report inventory measuring the severity of depression in adolescents and adults. The BDI-II was revised in 1996 to be more consistent with DSM-IV criteria for depression. For example, individuals are asked to respond to each question based on a two-week time period rather than the one-week timeframe on the BDI. The BDI-II is widely used as an indicator of the severity of depression, but not as a diagnostic tool, and numerous studies provide evidence for its reliability and validity across different populations and cultural groups. |
