Pathological worry in major depression: a preliminary report

Area of Science:

• Psychiatry
• Clinical Psychology
• Cognitive Science

Background:

• Generalized anxiety disorder (GAD) and major depressive episode (MDE) are distinct psychiatric conditions.
• Pathological worrying is a core feature of GAD, but may also occur in MDE.
• The Penn State Worry Questionnaire (PSWQ) is a common tool for assessing worry.

Purpose of the Study:

• To compare the frequency and severity of worrying in individuals diagnosed with GAD versus MDE.
• To investigate whether high PSWQ scores are specific to GAD.
• To explore potential differences in the process and phenomenology of pathological worrying between GAD and MDE.

Main Methods:

• Administered the Penn State Worry Questionnaire (PSWQ) to 49 participants with GAD and 32 participants with MDE.
• Compared PSWQ scores between the GAD and MDE groups.
• Analyzed the implications of PSWQ scores for diagnostic specificity and the nature of pathological worrying.

Main Results:

• PSWQ scores were similarly elevated in both the GAD and MDE groups.
• High PSWQ scores were not specific to the diagnosis of GAD.
• Suggests potential similarities in the process of pathological worrying between GAD and MDE, excluding uncontrollability.

Conclusions:

• Elevated worry, as measured by the PSWQ, is not exclusive to GAD and is also prevalent in MDE.
• The process of pathological worrying may share similarities between GAD and MDE, with potential differences in cognitive schemata and phenomenological presentation.
• Further research is needed to explore the differences in worry experiences and presentation between GAD and MDE.
