Abstract :
[en] Introduction. There is now solid evidence for a relation between
adverse life events (ALE) and psychotic symptoms in patients with
psychosis and in the general population. A recent study has
shown that this relation may be partially mediated by stress
sensitivity, suggesting the influence of other factors. The aim of
this study was to assess the mediation effect of emotion
regulation strategies and stress sensitivity in the relation between
ALE and attenuated positive psychotic symptoms (APPS) in the
general population.
Methods. Hundred and twelve healthy volunteers were evaluated
with measures of APPS, emotion regulation strategies, ALE and
stress sensitivity.
Results. Results demonstrated that the relation between ALE,
hallucination and delusion proneness was completely mediated
by maladaptive emotion regulation strategies, but not by stress
sensitivity. However, in addition to maladaptive emotion
regulation strategies, stress sensitivity demonstrated a mediation
effect between ALE and attenuated positive psychotic positive
symptoms when positive psychotic symptoms were grouped
together.
Conclusions. There are probably several possible trajectories leading
to the formation of positive psychotic symptoms and the results of
the present study reveal that one such trajectory may involve the
maladaptive regulation of negative emotions alongside a certain
general vulnerability after experiencing ALE.
