This case study explores to what extent, if any, a subject's reporting varies depending upon whom the subject believes will view the data and the relationship the subject has with the reviewer. It also explores the variance in reporting if several days pass between the timeframe in question and the time of data collection.
The subject answered three suicidality-related scales (the Sheehan-Suicidality Tracking Scale, the Suicidality Modifiers, and the Alphs Dichotomous Impulsivity and Hopelessness Two Questions) for 24 distinct timeframes. The scales were rated three different ways for each timeframe. The first was for only the patient. Immediately afterward, the scales were answered for the subject's therapist. A few days later, the scales were again answered by the patient, but only for the patient. The three different interviews for the same timeframe were compared to investigate any deviations.
This case study found clinically relevant deviations between the three ratings completed for the same timeframe.
This case study illustrates that a patient's reporting of his or her symptoms of suicidality using a patient-rated scale can vary depending upon the context, distance from timeframe in question, and the patient's relationship with the reviewer of the data.
本案例研究探讨了受试者的报告在何种程度上（若存在的话）会因受试者认为谁将查看数据以及受试者与审阅者的关系而有所不同。它还探讨了在相关时间范围与数据收集时间之间相隔数天的情况下报告的差异。
受试者针对24个不同的时间范围回答了三个与自杀倾向相关的量表（希恩自杀倾向追踪量表、自杀倾向修正量表以及阿尔夫斯二分冲动与绝望两个问题量表）。每个时间范围的量表以三种不同方式进行评分。第一种是仅为患者评分。紧接着，为受试者的治疗师回答量表。几天后，患者再次回答量表，但仅为患者自己评分。对同一时间范围的三次不同访谈进行比较，以调查是否存在任何偏差。
本案例研究发现，针对同一时间范围完成的三次评分之间存在临床相关偏差。
本案例研究表明，患者使用患者自评量表报告其自杀倾向症状时，可能会因情境、与相关时间范围的间隔以及患者与数据审阅者的关系而有所不同。
