Previous studies have found an increased prevalence of mixed/left handedness in male combat veterans and children with posttraumatic stress disorder (PTSD). This study examined lateral preference and screened for possible PTSD using a self-completion instrument in a general population sample (N = 596). Fifty-one individuals met all criteria for possible diagnosis of PTSD and, significantly, this group contained relatively more left handers; this effect was associated with strong left-handedness, rather than weak or mixed handedness. Left handers were found to have significantly higher scores in arousal symptoms of PTSD. This study extends previous findings to a civilian population and to women and suggests the association with left handedness may be a robust finding in people with PTSD.
先前的研究发现，男性退伍军人和患有创伤后应激障碍（PTSD）的儿童中，混合用手/左利手的比例有所增加。本研究在一个普通人群样本（N = 596）中，使用一份自填式问卷对用手偏好进行了调查，并筛查了可能存在的PTSD。51名个体符合PTSD可能诊断的所有标准，值得注意的是，这一组中左利手的比例相对较高；这种效应与强左利手有关，而非弱左利手或混合用手。研究发现，左利手在PTSD的觉醒症状方面得分显著更高。本研究将先前的研究结果扩展到了普通人群以及女性群体，并表明左利手与PTSD之间的关联可能是PTSD患者中的一个普遍发现。
