 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. Please note that in case one or more items are missing, **no** sum score is calculated.

-Finally, participants with suspiciosly high scores have been flagged. In other words, participants with 'very much' for each LDI item or 'yes' on each LTI item received such indication. Note that these subjects should not necessarily be excluded: these are very few cases suggesting they might actually represent the unfortunate few who went through all of these events in the past year.\\+Finally, participants with suspiciously high scores have been flagged.
