The SDS, developed by American researchers Zung (1965), is specifically designed to evaluate the degree of depression in participants. The survey comprises 20 items, and participants express their feelings using a Likert scale ranging from 1 (Never) to 4 (Always). The SDS has been widely utilized worldwide to measure depression levels, demonstrating strong internal consistency and validity (Cronbach's Alpha = 0.832), and has been well-established in clinical and research settings (Campo-Arias et al., 2006).

The SAS developed by American researchers Zung, (2013), is tailored to assess the anxiety level of participants. This instrument consists of a concise 20-item questionnaire, and participants use a Likert scale ranging from 1 (Strongly Disagree) to 4 (Strongly Agree) to express their emotions. The SAS exhibits robust psychometric properties in assessing participants' anxiety levels, with acceptable reliability values. The internal consistency, measured through Cronbach's Alpha, is 0.897, and the test-retest reliability, represented by the intra-class correlation coefficient (ICC), is 0.913 (Samakouri et al., 2012).
