====== List of Threatening Experiences (LTE) ======
The List of Threatening Experiences (LTE) is an instrument developed by Traolach Brugha and measures the occurrence of 12 major categories of stressful life events((Brugha TS, Cragg D (1990). The List of Threatening Experiences : the reliability and validity of a brief life events questionnaire. Acta Psychiatrica Scandinavica 82, 77–81)) via self-report ([[sections|section]]: [[mental health]]). The 12 major categories of stressful life events were selected for their established long-term consequences.\\
In Lifelines, the LTE is used in tandem with the [[stress (LDI)|Long-term Difficulties Inventory (LDI)]] to assess stress in participants.\\
[[stress_sum_scores|A sum score and suspiciousness flag]] for the LTE is available for use.
===== Background and validation =====
The LTE is a 12-item self report questionnaire that measures stressful life events. For each response category, participants indicated whether or not they experienced each of these events in the last 12 months (yes=1/no=0)((Brugha T, Bebbington P, Tennant C, Hurry J (1985). The List of Threatening Experiences : a subset of 12 life event categories with considerable long-term contextual threat. Psychological Medicine 15, 189–194.)).\\
The Dutch translation includes an additional thirteenth question: “Did you experience any other major severe negative events (yes/no)? If yes, briefly describe what happened?”
Item scores are summed to derive a total score((Rosmalen J.G.M., Bos E.H., de Jonge P (2012). Validation of the Long-term Difficulties Inventory (LDI) and the List of Threatening Experiences (LTE) as measures of stress in epidemiological population-based cohort studies. Psychological Medicine 42(12):2599-2608.)).
Inter- and intra-rater reliability were assessed for the LTE1)3) and only for one item (concerning something valuable that was lost or stolen) the intra-rater variability was not significant. Intra-rater reliability of the Dutch version is only available for the lifetime version of the questionnaire, which was assessed twice approximately two years apart (covering the same period).
===== Variables =====
The LTE questionnaire has been used several times in general assessments ([[1A Questionnaire 2|1A]], [[1B]], [[1C]], [[2A Questionnaire 1|2A]]) as well as in additional assessments [[ACTQ]], [[BIONIC|DEAQ]]), [[MHDQ]],([[NEXT]]. The main question differed between the assessments as follows:
| **Main Question in English** | **Main Question in Dutch** | **Code** | **Variable** | **Assessment** | **Age** |
| Could you indicate whether you experienced this unpleasant event in the past year? | Wilt u aangeven of u deze onplezierige gebeurtenis afgelopen jaar hebt meegemaakt? | lte_pastyear_adu_q_x | BRUGHAx | [[1A Questionnaire 2|1A]] [[1B]] [[1C]] [[2A Questionnaire 1|2A]] [[3B]] [[MHDQ]] | 18+ |
| Could you indicate whether you experienced this since you filled in Lifelines vragenlijst 4 ([[2A questionnaire 1|2A]])? | Wilt u aangeven of u deze hebt meegemaakt sinds de keer dat u Lifelines vragenlijst 4 ([[2A questionnaire 1|2A]]) invulde? | lte_followup_adu_q_x | BRUGHBx | [[ACTQ]] | 18+ |
| Could you indicate whether you experienced the following events during your pregnancy? | Kunt u aangeven of u onderstaande gebeurtenissen tijdens uw zwangerschap hebt ervaren? | lte_pregnancy_adu_q_x | BRUGHAPREGx | [[NEXT]] | 18+ |
| Could you indicate whether you experienced the following events after the birth pf your child? | Kunt u aangeven of u onderstaande gebeurtenissen na de geboorte van uw kind hebt ervaren? | lte_postpartum_adu_q_x | BRUGHC | [[NEXT]] | 18+ |
| did you experience one or more of these events in the 3 months prior to the period in which you felt down, empty or depressed? | Hebt u één of meer van deze gebeurtenissen meegemaakt in de 3 maanden voor de periode waarin u somber, leeg of depressief voelde? | lte_mdd_adu_q_x | BRUGHDx | [[BIONIC|DEAQ]] | 18+ |
| did you experience one or more of these events in the 3 months prior to the period in which you felt excessively anxious or worried? | Hebt u één of meer van deze gebeurtenissen meegemaakt in de 3 maanden voor de periode waarin u zich overmatig angstig of bezorgd voelde? | lte_gad_adu_q_x | BRUGHEx | [[BIONIC|DEAQ]] | 18+ |
Virtually no changes have occurred in the list of 13 stressful events that participants had to choose from (yes/no). Only for event 13, 'other negative events', there were three open text fields to fill-in during general assessments and the [[MHDQ]] and this was reduced to one open text field in [[ACTQ]] and [[BIONIC|DEAQ]].
