This study examined 12-month test-retest reliability of the Structured Clinical Interview for DSM-III-R Personality Disorders (SCID-II) in cocaine-dependent patients. Thirty-one patients completed the SCID-II during the second week of hospitalization for cocaine dependence, and again 12 months later. In both interviews, patients were asked to answer questions about their personality during the several years preceding admission to the hospital. Test-retest reliability, as measured by kappa, was relatively poor at .46. However, reliability of negative diagnoses (the absence of a disorder at both time points) was higher than reliability of positive diagnoses (the presence of a disorder at both time points). Reasons for the difficulty in attaining long-term test-retest reliability of axis II diagnoses in cocaine-dependent patients are discussed.
本研究考察了《精神疾病诊断与统计手册》第三版修订本（DSM-III-R）人格障碍结构化临床访谈（SCID-II）在可卡因依赖患者中的12个月重测信度。31名患者在因可卡因依赖住院的第二周完成了SCID-II访谈，12个月后再次进行访谈。在两次访谈中，患者均被要求回答有关入院前几年其人格的问题。以kappa系数衡量的重测信度相对较差，为0.46。然而，阴性诊断（两个时间点均无疾病）的信度高于阳性诊断（两个时间点均存在疾病）的信度。文中讨论了可卡因依赖患者在获得轴II诊断的长期重测信度方面存在困难的原因。
