The long-term associations of childhood parental loss with attachment, creativity, and epigenetic regulation
Open accessAbstract
The loss of a parent during childhood is a profound event with enduring impacts on psychological and emotional development. This study investigates the long-term effects of childhood parental loss on attachment patterns and openness to experience, with a focus on the epigenetic modulation of the oxytocin and dopamine systems. The sample included 371 participants (51.2% women, ages 26-43), of whom 33 experienced parental loss during childhood. In those individuals who lost a parent, findings revealed comparably lower attachment avoidance and a DNA methylation profile associated with a potential for increased oxytocin activity. Additionally, a DNA methylation profile associated with a potential for heightened dopamine activity was identified in this group, aligning with greater creativity. These findings highlight the intricate interplay of genetic and environmental factors in fostering resilience and personal growth, shedding light on the roles of oxytocin and dopamine in social bonding and the potential for long-term adaptation following early-life trauma.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
