(2) parents_synthetic.xlsx - SYNTHETIC dataset with the same columns as the original parent survey (Germany, May-June 2025), generated from the item means and covariances of the original data with the original missingness pattern; it contains no real respondent.

(4) output/ - all result tables and figures written by the script on the original data, plus sessionInfo. (5) LPA_replication_run.log - console log of the complete run on the original data. Data availability: the original survey data (N = 875 submitted questionnaires; N = 579 analytic sample) are available from the author on reasonable request for scientific purposes, subject to a data-use agreement, in a reduced form (analysis variables only; coarsened demographic variables). Interview transcripts and the key linking interviews to survey records are not shared because of the risk of re-identification. Licence: code MIT; synthetic data and documentation CC BY 4.0.
