Summary
This study validated a coding system for emotional overinvolvement (EOI) in psychiatric patients' relatives. The system reliably measured EOI aspects, showing good convergent validity but mixed results for discriminant validity.
Area of Science:
- Psychology
- Clinical Psychology
- Psychiatry
Background:
- Emotional overinvolvement (EOI) in relatives of psychiatric patients is linked to patient outcomes.
- A reliable and valid measure of EOI is needed for research and clinical practice.
Purpose of the Study:
- To assess the reliability and construct validity of a behavioral observation coding system for EOI.
- To examine the intrusiveness, excessive self-sacrifice, and exaggerated emotional response components of EOI.
Main Methods:
- Behavioral ratings of relatives' EOI were collected during problem-solving interactions.
- Participants included adult outpatients with obsessive-compulsive disorder or panic disorder with agoraphobia and their relatives.
- Interrater reliability, multitrait-multimethod matrix, and confirmatory factor analysis were used to evaluate the system.
Main Results:
- The interrater reliability for the EOI scales was adequate to excellent.
- The scales captured related but distinct aspects of the EOI construct.
- Convergent validity was supported, but discriminant validity findings were equivocal.
Conclusions:
- The developed coding system demonstrates good reliability and convergent validity for measuring EOI.
- Further research is needed to clarify the discriminant validity of the EOI components.
