To investigate whether assessment method influences the type of post-concussion-like symptoms.
Participants were 73 Australian undergraduate students (Mage = 24.14, SD = 8.84; 75.3% female) with no history of mild traumatic brain injury (mTBI). Participants reported symptoms experienced over the previous 2 weeks in response to an open-ended question (free report), mock interview and standardized checklist (British Columbia Post-concussion Symptom Inventory; BC-PSI).
In the free report and checklist conditions, cognitive symptoms were reported significantly less frequently than affective (free report: p < 0.001; checklist: p < 0.001) or somatic symptoms (free report: p < 0.001; checklist: p = 0.004). However, in the mock structured interview condition, cognitive and somatic symptoms were reported significantly less frequently than affective symptoms (both p < 0.001). No participants reported at least one symptom from all three domains when assessed by free report, whereas most participants did so when symptoms were assessed by a mock structured interview (75%) or checklist (90%).
Previous studies have shown that the method used to assess symptoms affects the number reported. This study shows that the assessment method also affects the type of reported symptoms.
研究评估方法是否会影响脑震荡样症状的类型。
参与者为73名无轻度创伤性脑损伤（mTBI）病史的澳大利亚本科生（年龄中位数=24.14，标准差=8.84；75.3%为女性）。参与者针对一个开放式问题（自由报告）、模拟访谈和标准化清单（不列颠哥伦比亚脑震荡症状量表；BC-PSI）报告了过去两周内经历的症状。
在自由报告和清单条件下，认知症状的报告频率显著低于情感症状（自由报告：p<0.001；清单：p<0.001）或躯体症状（自由报告：p<0.001；清单：p=0.004）。然而，在模拟结构化访谈条件下，认知和躯体症状的报告频率显著低于情感症状（均p<0.001）。通过自由报告评估时，没有参与者报告来自所有三个领域的至少一种症状，而当通过模拟结构化访谈（75%）或清单（90%）评估症状时，大多数参与者报告了所有三个领域的症状。
先前的研究表明，用于评估症状的方法会影响报告的症状数量。本研究表明，评估方法也会影响报告症状的类型。
