Beck Anxiety Inventory (BAI): was developed by Dr. Aaron T. Beck and it is a brief measure of anxiety with a focus on somatic symptoms of anxiety such as nervousness, dizziness, inability to relax (Beck et al., 1988). It has a total of 21 items that takes approximately 10-15 minutes to complete. Answers are on a 4-point Likert scale and range from 0 (not at all) to 3 (severely). The values for each item are added together to get an overall or total score for all 21 symptoms that can vary from 0 to 63 points. A total score of 0 - 7 indicates "Minimal" anxiety; 8 - 15 indicates "Mild" anxiety; 16 -25 indicates "Moderate" anxiety; and 26 - 63 indicates "Severe" anxiety

The DERS is a 36-item self-reported questionnaire that assesses an individual's ability to regulate their emotions (Gratz & Roemer, 2004). Participants rate items on a 5-point Likert scale (1 = seldom to 5 = nearly frequently) to represent their self-perceived reactions to stressful emotional situations. The DERS produces an overall difficulty score in ER as well as six subscales: (a) Awareness, (b) Clarity, (c) Nonacceptance, (d) Impulsivity, (e) Goals, and (f) Strategies. Subscales are evaluated in such a way that higher values imply more difficulty.
