*2.2. Psychological Status Measurement*

The following questionnaires were used to collect psychological variables:

Beck Depression Inventory–II (BDI–II), to determine depression symptoms' existence and severity, consisting of 21 items. The scoring scale is as follows: 0–9 (normal), 10–18 (mild depression), 19–29 (moderate depression), and 30–63 (severe depression), with an alpha coefficient of 0.87 [25,26].

State–Trait Anxiety Inventory (STAI), to evaluate anxiety as a temporary state (state anxiety) or as a personal characteristic (trait anxiety), consisting of 20 items each, with a Cronbach's α coefficient ranging from 0.82 to 0.92. Anxiety is considered as a state with scores over 20.54 ± 10.56 for males and 23.3 ± 11.93 for females, and a trait for scores over 20.19 ± 8.89 for males and 24.99 ± 10.05 for females [27,28].

Emotion Regulation Questionnaire (ERQ), to separately assess cognitive reappraisal or regulation before an emotional experience and expressive suppression after an emotional experience. This test consists of 10 items: 6 items assess cognitive reappraisal, with a score of 4.73 ± 1.03 for men and 4.85 ± 1.0 for women and a Cronbach's α coefficient of 0.79, and 4 items assess expressive suppression, with a score of 3.80 ± 1.22 for men and 3.15 ± 1.24 for women and a Cronbach's α coefficient of 0.75 [29,30].

Positive and Negative Affect Schedule (PANAS), to evaluate subject's emotional recognition of positive or negative affect, either as a trait or a state (trait or state positive affect, trait or state negative affect). It consists of 20 items each for both trait and state. A score of 30.23 ± 6.16 for males and 30.37 ± 6.08 for females denotes positive affect with a Cronbach's α coefficient of 0.87–0.89, and a score of 20.61 ± 6.54 for males and 22.69 ± 6.83 for females denotes negative affect with a Cronbach's α coefficient of 0.89–0.91 [31,32].
