Participants completed the PHQ-2, PHQ-9, GAD-7, and Mini-Z scales in two phases, with a three-month interval. The convergent validity of the test was determined by comparing it with the original version of the PHQ, an anxiety test (GAD-7), and a burnout test (Mini-Z). In addition, internal consistency was calculated using Cronbach's alpha coefficient and McDonald's omega coefficient.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The PHQ-2 showed a unidimensional structure, explaining 73% of the variance, and demonstrated strong convergent validity, with high correlations with the PHQ-9 (r = 0.836; p &amp;lt; 0.001) and the GAD-7 (r = 0.724; p &amp;lt; 0.001), and a moderate correlation with the Mini-Z (r = 0.568; p &amp;lt; 0.001).
