The interview‐administered Panic Disorder Severity Scale (PDSS) has been demonstrated to be a reliable and valid measurement of panic disorder severity. The purpose of this paper is to report on the reliability and usefulness of the self‐report form (PDSS‐SR). The PDSS and PDSS‐SR were administered to 108 psychiatric outpatients with and without panic disorder. The internal consistency of the instruments was analyzed with Cronbach's alpha. Test‐retest reliability was assessed on 25 of these… 
Psychometric properties of the Spanish self-report version of the panic disorder severity scale.
Psychometric properties of the panic disorder severity scale: clinician-administered and self-report versions.
Psychometric properties of both the clinician-administered and self-report versions of the Panic Disorder Severity Scale suggest that total scores on each of the PDSS versions provide a useful indication of panic-related severity, but clinicians and researchers are cautioned against relying on scores from individual items to measure specific constructs due to their poor specificity.
The reliability and validity of the panic disorder self-report: a new diagnostic screening measure of panic disorder.
This study examined the Panic Disorder Self-Report (PDSR), a new self-report diagnostic measure of panic disorder based on the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders
Psychometric Properties of the Spanish Version of the Panic Disorder Severity Scale
The Spanish version of the Panic Disorder Severity Scale has similar psychometric properties as the previous versions and is a useful instrument to assess panic symptoms in clinical settings in Spanish-speaking populations.
French adaptation and validation of the Panic Disorder Severity Scale—self-report
The French version of the Panic Disorder Severity Scale – Self-Report has psychometric properties consistent with the original version and constitutes a valid brief scale to assess the severity of panic disorder and change in severity over time, both in research and clinical practice.
Psychometric Properties of the Worry Behaviors Inventory: Replication and Extension in a Large Clinical and Community Sample.
The WBI provides clinicians and researchers with a brief, clinically meaningful index of problematic behaviors that may guide treatment decisions and contribute to the understanding of maintaining factors in GAD.

Panic-agoraphobic spectrum: reliability and validity of assessment instruments.
A randomized, controlled trial of panic disorder treatment initiation in an emergency department chest pain center.
Panic disorder is common and severe in this sample of patients with chest pain and a screening measure and a brief structured interview allowed emergency physicians with no extra training to reliably diagnose panic disorder and initiate pharmacologic treatment.
Sertraline in the treatment of panic disorder: a flexible-dose multicenter trial.
Results support the safety and efficacy of sertraline for the short-term treatment of patients with panic disorder.
Cognitive-behavioral therapy, imipramine, or their combination for panic disorder: A randomized controlled trial.
Combining imipramine and CBT appeared to confer limited advantage acutely but more substantial advantage by the end of maintenance, and each treatment worked well immediately following treatment and during maintenance;CBT appeared durable in follow-up.

Reliability and Validity Assessment
The paper shows how reliability is assessed by the retest method, alternative-forms procedure, split-halves approach, and internal consistency method.

Use of selective serotonin reuptake inhibitors for the treatment of childhood panic disorder: a pilot study.
SSRIs appear to be a safe and promising for the treatment of children and adolescents with panic disorder, however, randomized controlled trials evaluating the effects of SSRIs and other interventions for treating panic disorder inChildren and adolescents are warranted.
Multicenter collaborative panic disorder severity scale.
The Panic Disorder Severity Scale is a simple, efficient way for clinicians to rate severity in patients with established diagnoses of panic disorder, however, further research with more diverse groups ofpanic disorder patients and with a broader range of convergent and discriminant validity measures is needed.
