Abstrakt: The unfolding of emotions over time (i.e., emotion dynamics) has been characterized by baseline, intraindividual variability and regulatory tendency (return time to baseline after deflection). Mounting evidence suggests that compared to healthy individuals, individuals with schizophrenia are characterized by a more negatively valenced baseline and a higher intraindividual variability. However, the regulatory tendency has not been investigated in schizophrenia so far. We hypothesize that the severity of positive symptoms is linked to increased emotional variability and that the severity of negative symptoms is associated with an increased regulatory tendency. Fifteen individuals diagnosed with schizophrenia took part in this pilot experience sampling study and reported their emotional state ten times a day. The dynamics of valence and arousal and their relationship with symptomatology were estimated with the DynAffect model. Regulatory tendency in valence and arousal was positively associated with negative symptom severity and negatively associated with positive symptom severity. However, the severity of positive symptoms was not credibly associated with the variability of valence. The study only partly corroborates findings on increased stress reactivity in schizophrenia, which might be due to the small sample size. However, results suggest that negative symptoms could stem from over-regulated emotion dynamics, which may impede goal-directed behavior.
