The purpose of the present study is to compare the frequency and nature of expected symptoms in Greece (a country where the chronic post-concussive syndrome is largely unknown) with that in Canada.
A symptom checklist was administered to two subject groups selected from local companies in Patras, Greece, and Edmonton, Canada, respectively. Subjects were asked to imagine having suffered head trauma with loss of consciousness in a motor vehicle accident and to check off symptoms, they expected might arise from the injury. For symptoms they anticipated, they were asked to select the period of time they expected those symptoms to persist.
In both the Greek and Edmontonian groups, the pattern of symptoms anticipated closely resembled the acute symptoms commonly reported by accident victims with minor head injury. Yet, while many Edmontonians also anticipated symptoms to last months or years, very few Greek subjects selected any symptoms as being likely to persist in a chronic manner.
In Greece, despite the frequent experience of minor head injury in motor vehicle accidents, there is a very low rate of expectation of any chronic sequelae from such an injury, contrasting greatly with the response shown in Canada, where the prevalence of the chronic post-concussive syndrome is higher. Symptom expectation in some countries may be an important factor in the development of the chronic post-concussive syndrome.
本研究旨在比较希腊（一个慢性创伤后综合征在很大程度上不为人知的国家）和加拿大预期症状的频率及性质。
分别对从希腊帕特雷和加拿大埃德蒙顿当地公司选取的两个受试组进行症状清单调查。受试者被要求想象在机动车事故中头部受伤并失去意识，并勾选他们预期可能因该损伤而出现的症状。对于他们预期的症状，要求他们选择预期这些症状会持续的时间段。
在希腊组和埃德蒙顿组中，预期症状模式与轻度头部受伤事故受害者通常报告的急性症状非常相似。然而，虽然许多埃德蒙顿人也预期症状会持续数月或数年，但很少有希腊受试者选择任何可能持续为慢性的症状。
在希腊，尽管机动车事故中轻度头部受伤很常见，但对这种损伤导致任何慢性后遗症的预期率非常低，这与加拿大的情况形成极大对比，在加拿大慢性创伤后综合征的患病率较高。在某些国家，症状预期可能是慢性创伤后综合征发展的一个重要因素。
