Abstract

Abstract: Validated retrospective self‐report symptom rating scales are recommended for posttraumatic stress disorder (PTSD) screening and treatment. However, such reports may be affected by a respondent's most intense ("peak") or most recent ("end") symptoms. The present study evaluated the correspondence between PTSD symptoms assessed using a standard past‐month retrospective rating scale and recorded by ecological momentary assessment (EMA) over the same period and tested hypotheses that retrospective scores would be predicted by peak and end‐period momentary symptoms. Male U.S. veterans ( N = 35) who served post‐9/11 completed the PTSD Symptom Checklist for DSM‐5 (PCL‐5) at baseline and 1 month later. For 28 days during the intervening period, they received quasi‐randomly timed text prompts to complete a modified version of the PCL‐5 at that moment. Using multiple regression modeling, controlling for the number of completed EMAs and time (days) since the last EMA, we assessed the predictability of follow‐up retrospective PCL‐5 scores by (a) the mean of all momentary scores and (b) peak and last‐day momentary scores. Retrospective PCL‐5 scores were closest to peak scores, d = −0.31, and substantially higher than overall mean, d = 0.99, and last‐day momentary scores, d = 0.94. In the regression model, peak symptom experiences and last‐day momentary symptoms uniquely predicted follow‐up PCL‐5 scores over and above significant prediction by overall mean momentary symptom scores. In sum, participants' self‐reported past‐month PTSD symptom severity did not simply reflect an average over time. Additional questioning is needed to understand peak and recent symptom periods reflected in these estimates. 抽象: Traditional and Simplified Chinese Abstracts by the Asian Society for Traumatic Stress Studies (AsianSTSS) 簡體及繁體中文撮要由亞洲創傷心理研究學會翻譯 Traditional Chinese 回顧性和短暫自我報告的創傷後壓力症之間的對應關係: 退伍軍人的峰值與終點效應的證據 摘要 經過驗證的回顧性自我報告症狀評分表被推薦用於創傷後壓力症的篩选和治療。然而, 這種報告可能會受到受訪者最強烈(「峰值」)或最近(「終點」)症狀的影響。本研究評估了使用標準的過去一個月的回顧性評分量表評估的創傷後壓力症症狀與同期生態瞬間評估(EMA)記錄的創傷後壓力症症狀之間的對應關係, 並檢驗了回顧性評分會被高峰期和末期的瞬間症狀所預測的假設。 9‐11事件後服役的男性美國退伍軍人(N = 35)在基線和1個月後完成了DSM‐5的創傷後壓力症症狀檢查表(PCL‐5)。在干預期的28天裡, 他們收到了準隨機定時的文字提示, 在那一刻完成了PCL‐5的修改版。使用多元回歸模型, 控制已完成的EMA數量和自上次EMA以來的時間(天數), 我們通過(a)所有瞬間得分的平均值和(b)峰值和最後一天的瞬間得分來評估後續回顧性PCL‐5得分的預測性。回溯性PCL‐5評分最接近峰值評分, d = ‐ 0.31, 並大大高於總體平均值, d = 0.99, 和最後一天的短暫評分, d =0.94. 在回歸模型中, 峰值症狀經歷和最後一天的短暫症狀可以獨特地預測後續的PCL‐5分數, 超過了總體平均瞬間症狀分數的顯著預測。總之, 參與者自我報告的過去幾個月創傷後壓力症症狀的嚴重程度並不簡單地反映了一段時間的平均值。需要進行額外的詢問以了解這些估計中所反映的高峰期和最近的症狀期。 Simplified Chinese 回顾性和短暂自我报告的创伤后压力症之间的对应关系: 退伍军人的峰值与终点效应的证据 摘要 经过验证的回顾性自我报告症状评分表被推荐用于创伤后压力症的筛选和治疗。然而, 这种报告可能会受到受访者最强烈(「峰值」)或最近(「终点」)症状的影响。本研究评估了使用标准的过去一个月的回顾性评分量表评估的创伤后压力症症状与同期生态瞬间评估(EMA)记录的创伤后压力症症状之间的对应关系, 并检验了回顾性评分会被高峰期和末期的瞬间症状所预测的假设。 9‐11事件后服役的男性美国退伍军人(N = 35)在基线和1个月后完成了DSM‐5的创伤后压力症症状检查表(PCL‐5)。在干预期的28天里, 他们收到了准随机定时的文字提示, 在那一刻完成了PCL‐5的修改版。使用多元回归模型, 控制已完成的EMA数量和自上次EMA以来的时间(天数), 我们通过(a)所有瞬间得分的平均值和(b)峰值和最后一天的瞬间得分来评估后续回顾性PCL‐5得分的预测性。回溯性PCL‐5评分最接近峰值评分, d = ‐ 0.31, 并大大高于总体平均值, d = 0.99, 和最后一天的短暂评分, d =0.94. 在回归模型中, 峰值症状经历和最后一天的短暂症状可以独特地预测后续的PCL‐5分数, 超过了总体平均瞬间症状分数的显著预测。总之, 参与者自我报告的过去几个月创伤后压力症症状的严重程度并不简单地反映了一段时间的平均值。需要进行额外的询问以了解这些估计中所反映的高峰期和最近的症状期。
