This article reports on the psychometric results of a new sef-report depression rating scale from three separate methodological research studies (pilot, main, and replication). Based on classical test theory, psychometric findings supported preliminary validity and reliability in the original study (N = 503), which consisted of a pilot study of 116 participants and a main study of 337 faculty and staff at a mid-Atlantic metropolitan university and 50 outpatients being treated for depression in a private psychiatric practice. The validity and reliability of the new scale was further supported in the replication study (N = 121), which consisted of 96 outpatients and 25 inpatients under treatment for depression. In all three studies, results revealed that severe depression is associated with altered perception, particularly impairment in color sensitivity. Implications for clinical application are discussed.
本文报告了一项新的自我报告抑郁评定量表在三项独立的方法学研究（预试验、主要研究和重复研究）中的心理测量结果。基于经典测验理论，心理测量结果支持了原始研究（N = 503）中的初步效度和信度，该原始研究包括一项对116名参与者的预试验以及一项针对大西洋中部一所大都市大学的337名教职员工和50名在私人精神病诊所接受抑郁症治疗的门诊患者的主要研究。新量表的效度和信度在重复研究（N = 121）中得到了进一步支持，该重复研究包括96名门诊患者和25名接受抑郁症治疗的住院患者。在所有三项研究中，结果均显示严重抑郁与感知改变有关，尤其是颜色敏感度受损。文中讨论了其临床应用的意义。
