The Clinician Interview-Based Impression of Change, plus carer interview (CIBIC-Plus), is widely used in antidementia drug trials. It comprises Likert scales for disease severity and changes, and written accounts summarizing semistructured interviews evaluating behavior, cognition, and function. Studies using the CIBIC-Plus have focused on the numeric scores to the exclusion of the textual data. Our study explored both sets of data to evaluate whether the CIBIC-Plus written data supported (a) the clinicians' global evaluation of patients' changes during treatment, and (b) the emergence of consistent treatment effects. The global (numeric) scales of change were inconsistently supported by the textual data provided in the CIBIC-Plus. No consistent treatment effects were noted. Methodological problems presently limit the retrospective use of the CIBIC-Plus textual data. Improved standardization of note-taking in the CIBIC-Plus textual data may allow for a better understanding of the typical profiles and clinical importance of changes seen in the course of dementia treatment.
基于临床医生访谈的变化印象加照护者访谈(CIBIC-Plus)被广泛用于抗痴呆药物试验。它包括疾病严重程度和变化的李克特量表,以及对行为、认知和功能进行评估的半结构式访谈的书面总结。使用 CIBIC-Plus 的研究主要集中在数字分数上,而忽略了文字数据。我们的研究探讨了这两组数据,以评估 CIBIC-Plus 的书面数据是否支持(a)临床医生对患者在治疗过程中的变化的总体评价,以及(b)一致的治疗效果的出现。CIBIC-Plus提供的文字数据对总体(数字)变化量表的支持并不一致。没有发现一致的治疗效果。目前,方法上的问题限制了 CIBIC-Plus 文本数据的回顾性使用。提高CIBIC-Plus文本数据记录的标准化程度,可以更好地了解痴呆症治疗过程中出现的变化的典型特征和临床重要性。
