Area of Science:

Psychiatry
Epidemiology
Public Health

Background:

Panic disorder (PD) is a prevalent and disabling mental health condition.
Subthreshold panic cases may be even more common than diagnosed PD.
Understanding subthreshold PD is crucial for public health and clinical practice.

Purpose of the Study:

To examine psychiatric comorbidities in individuals with subthreshold panic.
To assess work functioning and health-care utilization in subthreshold panic.
To add evidence on the comorbidity and disability associated with subthreshold PD.

Main Methods:

Utilized data from the national Health Care for Communities study (N=9585).
Assessed psychiatric disorders, employment, work productivity, and healthcare utilization.
Categorized participants into seven groups based on panic and subthreshold panic symptoms.

Main Results:

Found 40% prevalence of clinical and subthreshold panic in the general population.
Subthreshold panic significantly associated with increased odds of depression, anxiety, psychosis, bipolar, and substance use disorders.
Subthreshold panic linked to higher healthcare service utilization, but not service intensity.

Conclusions:

Psychiatric comorbidities and increased healthcare utilization are prevalent in subthreshold panic.
The relationship between panic symptom severity and mental health/functioning requires further study.
Findings highlight the need for research on subthreshold PD's long-term course and quality of life impact.
