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.

Multiple convenience and random samples, as well as research studies in both clinical and nonclinical sample [22] [1] [23] Internal consistency (Cronbach's alpha, split half, etc.) Good Cronbach's alpha reported at .88 for measuring depression [22] Inter-rater reliability: Good Kappas range from .64-.81 for depression. [24] Kappa for anxiety is ...
The two forms of anxiety are separated in the inventory, and both are given their own 20 separate questions. When participants rate themselves on these questions, they are given a 4-point frequency scale. The frequency scales differ between the two types of anxiety. There are two main forms of the Inventory, Form X and Form Y. [5]
The Zung Self-Rating Anxiety Scale (SAS) was designed by William W. K. Zung M.D. (1929–1992) a professor of psychiatry from Duke University, to quantify a patient's level of anxiety. [ 1 ] [ 2 ] The SAS is a 20-item self-report assessment device built to measure anxiety levels, based on scoring in 4 groups of manifestations: cognitive ...
The Screen for Child Anxiety Related Emotional Disorders (SCARED) is a self-report screening questionnaire for anxiety disorders developed in 1997. [1] The SCARED is intended for youth, 9–18 years old, [1] and their parents to complete in about 10 minutes. [2] It can discriminate between depression and anxiety, as well as among distinct ...
To implement the Hamilton Anxiety Rating Scale, the acting clinician proceeds through the fourteen items, evaluating each criterion independently in form of the five-point scale described above. Upon the completion of the evaluation, the clinician compiles a total, composite score based upon the summation of each of the 14 individually rated items.
The divisions include one scale for adults (AMA-A), one scale for college students (AMAS-C), and the other for the elderly population (AMAS-E). Each scale is geared towards examining situations specific to that age group. For example, the AMAS-C has items pertaining specifically to college students, such as questions about anxiety of the future.
