 Researchers from the [[https://www.rug.nl/staff/l.schweren/research|University Medical Center Groningen]] validated and created sum scores for questionnaire data on past-year stress exposure.

-After recoding, the sum scores are calculated by adding all LDI/LTE variables together.
+After recoding, the sum scores are calculated by adding all LDI or LTE items together.
 Please note that in case one or more items are missing, **no** sum score is calculated. The missing item is not imputed because stressful life events are generally thought of as being random. Imputing the occurrence of a random event based on the occurrence of another random event is not theoretically sound.
