The timing and number of recent stressful life events occurring in the year before onset of emotional or behavioural disorder was examined in a consecutive sample of children. Overall, events increase the relative risk of psychiatric disorder by 3-6 times. Events occur throughout the 12 months, but tend to cluster in the 16 weeks nearest onset of symptoms. The number of events influences the onset of disorder: cases with multiple events are more likely to have an event within 16 weeks of onset; cases with single events are more likely to have the event 36-52 weeks before onset. Cases whose onset occurs within 4 weeks of an event may have experienced single or multiple events. The results support the concept of additivity of recent stressful events in some cases of emotional and behavioural disorders in childhood.
在一组连续抽样的儿童中，研究了在情绪或行为障碍发作前一年中近期发生的应激性生活事件的时间和数量。总体而言，这些事件使精神障碍的相对风险增加3至6倍。事件在整个12个月内都会发生，但往往集中在最接近症状发作的16周内。事件的数量会影响障碍的发作：发生多起事件的病例在发作后16周内更有可能发生一次事件；发生单一事件的病例更有可能在发作前36至52周发生该事件。在事件发生后4周内发作的病例可能经历了单一或多起事件。这些结果支持了近期应激事件在儿童期某些情绪和行为障碍病例中具有累加性的概念。
