validity, and interpretability, whereas the SISST also received positive ratings for content validity and being able to distinguish patients from each other (see Stein, Modini, Hunt, & Abbott, 2017). Other questionnaires are available to the clinical researcher for the assessment of certain cognitive features related to anxiety. For example, anxiety sensitivity is the fear of anxiety- related bodily sensations, based on beliefs that the sensations signal catastrophic somatic, social, or psychological consequences (Taylor, 1999). Anxiety sensitivity was originally conceptualized as a unidimensional construct, as assessed by the 16-item Anxiety Sensitivity Index (ASI; Peterson & Reiss, 1992). ASI scores predict who will respond anxiously to panic- provocation challenges, and who is likely to develop panic attacks and panic disorder (Taylor, 1999). Taylor et al. (2007) developed an 18-item measure, the ASI-3, to assess the Physical (e.g., When my stomach is upset, I worry that I might be seriously ill”), Cognitive (e.g., “When my thoughts speed up, I worry that I might be going crazy”), and Social Concerns (e.g., “I worry that other people will notice my anxiety”) factors replicated in prior research. Numerous studies have found support for the factorial validity, internal consistency, and validity of the ASI-3 in various nonclinical and clinical samples (e.g., Taylor et al., 2007; Wheaton, Deacon, McGrath, Berman, & Abramowitz, 2012). Several other anxious self-statement measures are worth noting. The Anxious Self- Statement Questionnaire (ASSQ; Kendall & Hollon, 1989) is a 32-item measure of the Cognitive Assessment 11

frequency of anxious thoughts that has excellent reliability, concurrent validity, and ability to discriminate between known groups, although Glass & Arnkoff (1997) question its discriminant validity with respect to depression. The Cognition Checklist (CCL) developed by Beck and colleagues (Beck, Brown, Steer, Eidelson, & Riskind, 1987) assesses the frequency of 12 cognitions related to danger and presumed to be characteristic of anxiety disorders (CCL-anxiety) and 12 thoughts centered on loss and failure characteristic of depression (CCL-depression). In a meta-analysis of 13 studies, R. Beck and Perkins (2001) found that the CCL-anxiety scale did not discriminate between anxious and depressive symptomatology. A number of self-report measures have been developed to measure cognitive aspects of specific anxiety disorders, including generalized anxiety disorder, social anxiety disorder, panic disorder, agoraphobia, obsessive-compulsive disorder, and posttraumatic stress disorder. In terms of cognitive aspects of generalized anxiety disorder, the Penn State Worry Questionnaire (PSWQ; Meyer, Miller, Metzger, & Borkovec, 1990) is a widely used 16-item measure that assesses an individual’s tendency to worry excessively and chronically (e.g., “Once I start worrying I cannot stop”). The PSWQ provides a reliable and valid measure of worry. The PSWQ has demonstrated utility across a wide range of diagnostic groups, while exhibiting

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
