Expressed emotion in an 8 year follow-up.

Area of Science:

• Psychiatry
• Clinical Psychology
• Mental Health Research

Background:

• Expressed emotion (EE) is a measure of the emotional atmosphere within a family environment.
• Previous research suggests a link between high EE and relapse in schizophrenia, but long-term predictive validity and influencing factors require further investigation.

Purpose of the Study:

• To determine the 8-year predictive validity of expressed emotion (EE) on the course of schizophrenia.
• To investigate if the predictive validity of EE is influenced by the duration of illness and living arrangements (patients living with parents).

Main Methods:

• An 8-year follow-up study of 69 out of 99 schizophrenia patients initially assessed using Camberwell Family Interviews (CFI), Global Assessment Scale (GAS), and symptom scores.
• Data collected included rehospitalizations, symptom scores, and GAS scores at baseline and after 8 years.

Main Results:

• High EE predicted poorer outcomes (more frequent and longer hospitalizations, higher symptom and GAS scores) in patients with a longer duration of illness (> 4.5 years).
• No significant difference in outcome based on EE levels was found for patients with shorter illness duration (< 4.5 years) or those living with partners.
• The predictive effect of EE was consistent across the 8-year follow-up and independent of whether patients lived with their parents.

Conclusions:

• Expressed emotion (EE) is a significant long-term predictor for the course of schizophrenia.
• The predictive power of EE is independent of living arrangements, suggesting a complex relationship beyond simple environmental causality.
