Our classificationSummed life-events: equal weight
Life events were assessed with a 65-item inventory 
developed by revising the SRRS (Holmes & Rahe, 1967) 
and adding positive life events.

Residents were asked two questions about each event 
listed on the inventory
-first, whether the event had taken place in their 
lives during the last year
-second, to rate, whether the event "turned out" 
positive,(PE), negative, (NE),
had both positive and negative outcomes,
or had no effect on them.Events rated as having both 
positive and negative outcomes were not scored for PE 
and NE (about 10%).
They were counted together with the total number of 
events reported, TE.
