Abstract

It has been suggested that genes impact on the degree to which minor daily stressors cause variation in the intensity of subtle paranoid experiences. The objective of the present study was to test the hypothesis that catechol‐O‐methyltransferase (COMT) Val 158 Met and brain‐derived neurotrophic factor (BDNF) Val 66 Met in part mediate genetic effects on paranoid reactivity to minor stressors. In a general population sample of 579 young adult female twins, on the one hand, appraisals of (1) event‐related stress and (2) social stress and, on the other hand, feelings of paranoia in the flow of daily life were assessed using momentary assessment technology for five consecutive days. Multilevel regression analyses were used to examine moderation of daily life stress‐induced paranoia by COMT Val 158 Met and BDNF Val 66 Met genotypes. Catechol‐O‐methyltransferase Val carriers displayed more feelings of paranoia in response to event stress compared with Met carriers. Brain‐derived neurotrophic factor Met carriers showed more social‐stress‐induced paranoia than individuals with the Val/Val genotype. Thus, paranoia in the flow of daily life may be the result of gene–environment interactions that can be traced to different types of stress being moderated by different types of genetic variation.

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.
