The 27-item instrument assesses an individual's risk of having depression, anxiety disorder, posttraumatic stress disorder, and bipolar disorder, as well as items for drug and alcohol use and functional impairment.
The reliability scores of the scales in terms of Cronbach's alpha scores rate the Depression scale at 0.91, the Anxiety scale at 0.84, and the Stress scale at 0.90 in the normative sample. The means and standard deviations for each scale are 6.34 and 6.97 for depression, 4.7 and 4.91 for anxiety, and 10.11 and 7.91 for stress, respectively.
They are popular because they can be inexpensive to give and to score, and their scores can often show good reliability. There are three major approaches to developing self-report inventories: theory-guided, factor analysis, and criterion-keyed. Theory-guided inventories are constructed around a theory of personality or a prototype of a construct.
Though the BAI was developed to minimize its overlap with the depression scale as measured by the Beck Depression Inventory, a correlation of r=.66 (p<.01) between the BAI and BDI-II was seen among psychiatric outpatients, [29] suggesting that the BAI and the BDI-II equally discriminate between anxiety and depression.

Using a cut-off of 8 the GAD-7 has a sensitivity of 92% and specificity of 76% for diagnosis generalized anxiety disorder. The following cut-offs correlate with level of anxiety severity: Score 0-4: Minimal Anxiety; Score 5-9: Mild Anxiety; Score 10-14: Moderate Anxiety; Score greater than 15: Severe Anxiety

When the test is scored, a value of 0 to 3 is assigned for each answer and then the total score is compared to a key to determine the depression's severity. The standard cut-off scores were as follows: [7] 0–9: indicates minimal depression; 10–18: indicates mild depression; 19–29: indicates moderate depression; 30–63: indicates severe ...
The team used health data from more than 350,000 people who had been recruited for the UK Biobank study between 2006 and 2010 and participated in follow-up assessments three times over the next ...
