Two dimensional views of psychopathology

Area of Science:

• Psychology
• Psychopathology Research

Background:

• Dimensional views propose psychopathology symptoms exist on a continuum with normal experience.
• Two key perspectives are the phenomenological view and the vulnerability view.

Purpose of the Study:

• To review research on dimensional views of psychopathology.
• To evaluate the adequacy of current research strategies for testing these views.

Main Methods:

• Review of research utilizing questionnaires from H. J. Eysenck and L. J. Chapman.
• Analysis of existing study designs for testing phenomenological and vulnerability models.

Main Results:

• Current research strategies are insufficient for adequately testing the phenomenological view of psychopathology.
• Existing evidence provides only weak support for the vulnerability view.

Conclusions:

• More direct and robust research methodologies are needed to validate dimensional models of psychopathology.
• Future research should focus on improved strategies to test the phenomenological and vulnerability hypotheses.
