9.88.2. History

  • List of Threatening Experiences:

    • 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. https://www.ncbi.nlm.nih.gov/pubmed/3991833

    • Brugha TS, Cragg D (1990). The List of Threatening Experiences: the reliability and validity of a brief life events questionnaire. Acta Psychiatr Scand. 82: 77-81. https://www.ncbi.nlm.nih.gov/pubmed/2399824

      Defines the LTE-Q, the questionnaire version of the life events instrument, consisting (as before) of 12 categories of common life events that are highly likely to be threatening. No definitive scoring system is described.

    • Rosmalen JGM, Bos EH, 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: 2599–2608. https://www.ncbi.nlm.nih.gov/pubmed/22490940

      Uses a scoring system of “the total number of items endorsed” (out of 12).

9.88.3. Source

  • Mary-Ellen Lynall, personal communication to Rudolf Cardinal (e.g. 2019-04-30).

  • The IAM/Life Events version asks occurrence within the last 6 months; then about severity of index event and frequency (since age 18) for each category of event endorsed.

  • The differences in categories from the LTE are:

    LTE-Q category IAM/Life Events category
    1: Illness/injury/assault (self) [1: same]
    2: Illness/injury/assault (relative) [2: same]
    3: Parent/child/spouse died [3: same except includes siblings]
    4: Close family friend/other relative died [4: same, given 3]
    5: Marital separation 5: marital separation or broke off relationship
    6: Broke off a steady relationship [incorporated into 5]
    6: ended long-lasting friendship with close friend/relative
    7: Problems with close friend/neighbour/relative [7: same]
    8: Unemployment or unsuccessful job-seeking 1mo+ 8: unsuccessful job-seeking 1mo+
    9: Sacked [9: same: sacked/made redundant]
    10: Financial crisis [10: same]
    11: Police with court appearance [11: same]
    12: Something lost/stolen [12: same]
    13: Self/partner gave birth
    14: Other

    Note: in the draft IAM/Life (prior to 2019-09-15), 8 was “sacked” and 9 was “unsuccessful job-seeking”; transposed on 2019-09-15 for better consistency with original LTE-Q.
