This poll is on the type of onset you experienced. Because some studies have shown stressful events prior to onset are increased in general in ME/CFS it includes a stress component. Besides something as obvious as a chronic illness, loss of job or to the family researchers can include such events as starting a new job, moving to a new location and entering a new school as stressful events. Its up to you to decide if you were under 'increased stress' at the time.
