Background
The presence of psychiatric disorders in earlier in life is the strongest predictor of late-life psychiatric disorders. Up until the K-wave, limited information on lifetime psychiatric disorders was available in LASA. Therefore, from the K-wave onwards a brief questionnaire assessing the lifetime presence of a wide range of psychiatric disorders was asked in the main interview to all participants.
Measurement instrument in LASA
We selected and adapted five items from the Lifetime Depression Assessment Self-report (LIDAS), an online tool developed at the department of psychiatry of the VU medical center in the Netherlands (Bot et al., 2017). The LIDAS was developed as a brief alternative to extensive diagnostic questionnaires. Although LIDAS was specifically primed to measure the lifetime presence of Major Depressive Disorders and depressive symptoms, it also includes questions that ask for the lifetime presence of other psychiatric disorders and previous contacts with mental health care in general.
The inclusion of these items from the LIDAS in LASA complements the already available measures of anxiety diagnoses and depression diagnoses and depression algorithm.
The items ask for:
- Ever being in contact with mental health care;
- Ever being diagnosed with specific mental disorders (checklist of 13 plus ‘other’ category) by a caregiver or doctor;
- Age of onset
- Ever received treatment (yes/no)
- Ever received specific forms of treatment (checklist of 7 plus ‘other’ category)
In the original LIDAS, specificity and sensitivity of lifetime MDD were both 85%, and the population-based adult prevalence was 20.8%. However, these statistics are not applicable to the LASA version as LASA uses only a selection of items.
