Factor Invariance Of Premorbid Social Competence Across Multiple Population Of Schizophrenics

Area of Science:

• Psychiatry
• Psychology
• Social Science

Background:

• Social competence is crucial for schizophrenia diagnosis and prognosis.
• Previous research explored the dimensionality and invariance of social competence across patient groups.

Purpose of the Study:

• To re-analyze existing data (Zigler and Levine, 1981) using a simultaneous test.
• To examine the factor structure of the Zigler-Phillips social competence scale across multiple samples.

Main Methods:

• Simultaneous testing of the factor structure.
• Analysis across multiple patient samples varying by gender and hospital type.

Main Results:

• An invariant two-factor structure for social competence was established.
• Factor means differed across groups, aligning with prior evidence.

Conclusions:

• The two-factor structure of social competence is invariant across different patient demographics (gender, hospital type).
• Findings support the reliable use of the social competence construct in schizophrenia research and clinical practice.
