Results from the Mini Neuropsychiatric Interview (MINI) performed among adult Lifelines participants at general assessments 1A and 2A were processed into derivatives by the University Center of Psychiatry, according to the manual for MINI version 5.0.0.
These derivatives should be used to define if a participant meets the criteria for a certain psychiatric diagnosis (sections: mental health and secondary & linked variables).

The MINI derivatives can be requested in the Lifelines catalogue. When this data has been used in your research, you will have to include a reference to the the following paper:

• van Loo, H. M., Beijers, L., Wieling, M., de Jong, T. R., Schoevers, R. A., & Kendler, K. S. (2023). Prevalence of internalizing disorders, symptoms, and traits across age using advanced nonlinear models. Psychological medicine, 53(1), 78-87.

Derivatives are available for all Lifelines versions of the MINI.
Note that MINI v1 differs significantly from the other versions in that the available derivatives pertain to 'last year' instead of 'current' diagnoses and were made in R. For all other versions derivates have been calculated using SPSS syntax.
For the (digital) MINI v4 used in assessment 2A, items that were subdivided from the original MINI v2-v3 items were rejoined, which made calculations of derivatives and comparison with the other versions possible.
