We developed a Structured Interview Guide for the Hamilton Anxiety Scale (SIGH-A) and report on a study comparing this version to the traditional form of this scale. Experienced interviewers from three Anxiety Disorders research sites conducted videotaped interviews using both traditional and structured instruments in 89 participants. A subset of the tapes was co-rated by all raters. Participants completed self-report symptom questionnaires. We observed high inter-rater and test-retest reliability using both formats. The structured format produced similar but consistently higher (+ 4.2) scores. Correlation with a self-report measure of overall anxiety was also high and virtually identical for the two versions. We conclude that in settings where extensive training is not practical, the structured scale is an acceptable alternative to the traditional Hamilton Anxiety instrument.

The scale has previously shown good psychometric properties in a sample of Panic Disorder patients with no more than mild agoraphobia. The purpose of this paper is to confirm reliability and validity, to provide an estimate of a cut-score discriminating the presence or absence of current DSM-IV Panic Disorder, and to determine the factor structure of the instrument. Procedures: 104 psychiatric outpatients, including 54 with current Panic Disorder, underwent structured diagnostic assessment and the PDSS interview. The PDSS was repeated within 3-17 days. Results: we confirmed reliability and validity of the instrument and found a one-factor solution fit the data. A cut-off score of eight identifies patients with current panic with a sensitivity of 83.3%, and a specificity of 64%. Conclusion: the PDSS is a simple, reliable instrument for use in Panic Disorder studies. A cut-score of eight may be useful as a tool to screen patients in settings such as primary care, for diagnosis-level symptoms. #
