Cronbach\u2019s alpha coefficient was 0.832 and the intraclass correlation coefficient (1, 2) was 0.811 (95% CI 0.650 to 0.898). Significant correlations were observed for concurrent validity (r=0.699, p&lt;0.01) and predictive validity (\u03c1=0.538, p&lt;0.01). The area under the receiver operating characteristic curve was 0.799 (CI 0.629 to 0.970). A cut-off value of 28 points was obtained from the Youden index and demonstrated a sensitivity of 1.000, specificity of 0.553, positive predictive value (PPV) of 0.190 and negative predictive value of 0.000.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study developed a simple screening scale for predicting postdischarge depression in patients with ACS-PCI (SDACS-12) and demonstrated its reliability, validity and predictive ability with 12 items.
