Clinical Markers of Panic and Generalized Anxiety Disorder

October 4, 2023 updated by: Alice Caldiroli, University of Milano Bicocca

Generalized Anxiety Disorder and Panic Disorder: Differences in Clinical Manifestation and Prognosis, a Multicenter Study

The goal of this observational study is to compare socio-demographic and clinical features in patients affected by Generalized Anxiety Disorder (GAD) and by Panic Disorder (PD). The main questions it aims to answer are:

  • which socio-demographic/clinical markers are associated to GAD or PD diagnosis?
  • which factors are associated with a longer duration of untreated illness (DUI) in GAD and in PD? Participants will signed a written informed consent and socio-demographic/clinical variables will be retrospectively collected. Researchers will compare GAD and PD groups in terms of socio-demographic and clinical features, including DUI, to better characterize the two disorders and to investigate factors associated to a longer DUI.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Outpatients suffering from PD or GAD identified from medical records in the pre-pandemic period (2016-2019).

Description

Inclusion Criteria:

  • age 18-65 years;
  • ability and willing to give informed consent;
  • fluency in Italian language;
  • diagnosis of GAD or PD according to the criteria of the Diagnostic and Statistical Manual of Mental Disorder, 5th edition.

Exclusion Criteria:

  • intellectual disability;
  • lack of clinical and socio-demographic information;
  • patients treated for less than three months in the outpatient clinics for the impossibility of a comprehensive collection of clinical variables.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Generalized Anxiety Disorder (GAD)
Patients affected by GAD
Diagnostic test: Structured Clinical Interview for DSM-5
A structured interview will be administered to confirm the diagnosis reported in clinical charts
Panic Disorder (PD)
Patients affected by Panic Disorder
Diagnostic test: Structured Clinical Interview for DSM-5
A structured interview will be administered to confirm the diagnosis reported in clinical charts

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Duration of untreated illness (DUI) in months = time between the onset of PD and the first appropriate pharmacological treatment.
Time Frame: Three months
Factors associated to DUI among GAD and PD groups. Information about DUI have been registered according to what the patient reported (clinical records and structured interviews)
Three months
