Internet Administration of Three Commonly Used Questionnaires in Panic Research: Equivalence to Paper Administration in Australian and Swedish Samples of People With Panic Disorder

An Internet-based investigation of the catastrophic misinterpretation model of panic disorder

“…Specifically, the first hypothesis that people with PD would give more harm-related interpretations of internal stimuli (using the narrow criterion of harm) than non-anxious controls was supported (based on both the initial interpretation and outcome measure). The second hypothesis that people with PD would give more harm-related interpretations of internal stimuli (using the narrow criterion of harm) than people with SAD was also supported, although the significant difference was found only for the outcome measure and not also the initial interpretation measure, Nevertheless, this finding substantially supports the hypothesis as the outcome measure has been shown to be the more psychometrically valid measure of the two (Austin et al, 2006a) and provides the best indication of an individual's overall threat appraisal. Despite this, given that the initial outcome measure did not also reveal a difference between people with PD and SAD (as the outcome measure did), this result requires replication.…”

“…The BSIQ-M has demonstrated good to excellent internal consistency, inter-rater reliability, and construct validity (Austin et al, 2006a). The original BSIQ on which the BSIQ-M is based has also demonstrated satisfactory test-retest reliability over 3 months (.73-.75) for the ranking sub-scales (Clark et al, 1997).…”

“…Scoring is based on the ranking given to the threat explanation: Ranked first (score = 2); ranked second (score = 1); ranked third (score = 0). For internal stimuli items, only a score based on the ranking given to the harm related option is calculated as the developers of the instrument found the psychometric properties of the anxiety ranked response scale to be poor and recommended it not be calculated (Austin et al, 2006a).…”

Maternal Fair/Poor Self-Rated Health and Adverse Infant Birth Outcomes

“…For example, over 75% of women consult the Internet on birth matters and their pregnancy (Declercq, Sakala, Corry, & Applebaum, 2007), with fetal health/development among the most popular topics (Larsson, 2009). Prior researchers have shown that health care screenings conducted in this style furnish easy and expedited access to large populations at very low cost (Austin, Carlbring, Richards, & Andersson, 2006;Buchanan, 2003). Examples of how SRH could be utilized are the interactive, self-administered question banks for expecting mothers on www.womenshealth.gov.…”

Can the Patient Decide Which Modules to Endorse? An Open Trial of Tailored Internet Treatment of Anxiety Disorders

“…Three of these established measures have been used in previous Internet trials and have robust psychometric properties for Internet delivery for various groups, including panic disorder (Austin, Carlbring, Richards, & Andersson, 2006), social phobia (Hedman et al, 2010), and depression (Holla¨ndare, Andersson, & Engstro¨m, in press). The exception is the CORE-OM, which was used in the previous controlled trial but has not been evaluated separately with regard to psychometric properties for online use.…”
