Evaluating Structural Models of Cognitive Vulnerabilities: Transdiagnostic and Specific Pathways to Internalizing...

Area of Science:

• Psychology
• Psychopathology
• Cognitive Science

Background:

• Internalizing psychopathology, including anxiety and depression, is prevalent.
• Understanding the structure of cognitive vulnerabilities is crucial for developing effective interventions.
• Existing models often struggle to differentiate shared versus unique risk factors.

Purpose of the Study:

• To examine the structure of cognitive vulnerabilities to anxiety and depression using a hierarchical approach.
• To evaluate the utility of a bifactor model in distinguishing a transdiagnostic factor from disorder-specific vulnerabilities.
• To assess the predictive validity of these factors for internalizing psychopathology.

Main Methods:

• A bifactor model was compared against other structural models (single factor, correlated factor, single hierarchical) in undergraduate and adolescent samples.
• Participants included 351 undergraduates and 385 adolescents.
• Statistical modeling was used to assess model fit and predictive relationships.

Main Results:

• The bifactor model demonstrated good fit across both samples, comparable to other evaluated models.
• A core transdiagnostic vulnerability factor and six specific cognitive vulnerability factors were identified.
• The transdiagnostic factor predicted general internalizing symptoms, while specific factors also showed unique predictive associations.

Conclusions:

• A bifactor model effectively captures both shared and specific cognitive vulnerabilities in internalizing psychopathology.
• Both a general transdiagnostic factor and unique cognitive styles contribute to anxiety and depression.
• These findings support an integrative etiologic model for understanding internalizing disorders.
