Key result
High family expressed emotion combined with greater electrodermal activity was associated with the highest levels of negative symptoms in recent-onset schizophrenia patients at 1-year follow-up.
Why the study?
Does the interaction of electrodermal activity and expressed emotion predict symptoms in recent-onset schizophrenia?
Observational (n=94)
Does the interaction of electrodermal activity and expressed emotion predict symptoms in recent-onset schizophrenia?
The combination of high family expressed emotion and sympathetic nervous system arousal (EDA) confers high risk for poor negative symptom outcomes in recent-onset schizophrenia.

May aid risk stratification in recent-onset schizophrenia; hypothesis-generating for targeted family or arousal interventions.
Subotnik et al. (2012) conducted an observational in Recent-onset schizophrenia (n=94). Electrodermal activity (EDA) and expressed emotion (EE) was evaluated on Psychiatric symptoms (negative symptoms). High family expressed emotion combined with greater electrodermal activity was associated with the highest levels of negative symptoms in recent-onset schizophrenia patients at 1-year follow-up.
