A total of N = 102 young people (aged 16–26) with low to moderate CA were included in the study. We first investigated associations between friendship quality, mental health, and CA.

In a representative subset (n = 62), we assessed neural stress responses using the Montreal Imaging Stress Task. In our sample, CA was best described along two dimensions resembling threat or deprivation like experiences. Hence, we investigated both cumulative and dimensional effects of CA.

All scripts and pseudonymized data necessary to reproduce the findings of this study are publicly available. For all significant ROIs, group-level statistical maps displaying t-values of neural activation (pFWE control) trials of the MIST have been uploaded to NeuroVault (https://neurovault.org/collections/AXXZBAGI/).
