Consistent with a continuum approach to mental health, a growing body of research has established that paranoia occurs in the general population. The stress-vulnerability model would predict an association between environments high in threat and the presence of state paranoia, even in those with low dispositional trait paranoia. The present research examines whether urban cycling, a naturalistic environment high in interpersonal threat, is associated with state paranoia - operationalised as an explicit perception that other road users intend the agent harm. 323 members of the general population who regularly cycled in London completed measures of state and trait paranoia, anxiety, depression and stress. The majority of the general population sample (70%) reported experiencing state paranoia during urban cycling, and there was no association between state paranoia and trait paranoia. Reported state paranoia was higher during urban cycling than when using the London underground (a lower threat environment) and reported state paranoia on the underground was associated with trait paranoia. The findings are consistent with the stress-vulnerability model of everyday paranoia.
与心理健康的连续体方法一致，越来越多的研究已经证实，偏执在普通人群中存在。应激易损性模型预测，即使在那些具有低特质性偏执倾向的人中，高威胁环境与状态偏执的存在之间也存在关联。本研究考察了城市自行车骑行这一自然环境中高度存在人际威胁的环境是否与状态偏执有关——即明确感知到其他道路使用者有意伤害自己。323 名经常在伦敦骑自行车的普通人群完成了状态和特质偏执、焦虑、抑郁和压力的测量。普通人群样本的大多数（70%）报告在城市骑自行车时经历过状态偏执，而且状态偏执与特质偏执之间没有关联。在城市骑自行车时报告的状态偏执比在使用伦敦地铁（一个威胁程度较低的环境）时更高，而在地铁上报告的状态偏执与特质偏执有关。这些发现与日常偏执的应激易损性模型一致。
