Reliability and validity of the self-report version of the Panic Disorder Severity Scale in Korea
Open accessAbstract
BACKGROUND: The self-report version of the Panic Disorder Severity Scale (PDSS-SR) has been developed recently and has demonstrated good psychometric properties. However, there is no cross-cultural evaluation of this scale. The purpose of this study was to confirm the reliability and validity of the PDSS-SR in Korean subjects. METHODS: We studied 148 patients with principal DSM-IV diagnoses of panic disorder who underwent formal structured diagnostic assessment and the PDSS interview. The participants completed self-report measures including the PDSS-SR, Anxiety Sensitivity Index-Revised, Albany Panic and Phobia Questionnaire, Beck Depression Inventory, Beck Anxiety Inventory, and Spielberger State-Trait Anxiety Inventory-Trait Version. RESULTS: The PDSS-SR had a single-factor structure, with all seven items having salient loadings. Cronbach's alpha for the PDSS-SR was .88 and intraclass correlation coefficient was .71 between PDSS-SR and PDSS. Also, the scale showed excellent 1-day test-retest reliability and demonstrated significant correlation with other anxiety-related measures. In addition, the PDSS-SR was sensitive to change with pharmacological treatment. CONCLUSIONS: The findings of this study strongly support the reliability and validity of the PDSS-SR. It is expected that this scale will be helpful in clinical settings and research protocols in Korea.

“We found a significant correlation between the PDSSSR and the BDI, which may be due to the fact that panic disorder and depressive symptoms co-occur frequently.([22]) There are some limitations in this study.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
