Somatic complaints are often key features of anxiety pathology. Although most measures of anxiety symptoms capture somatic complaints to some degree, the Self-Rating Anxiety Scale (SAS) was developed primarily as a measure of somatic symptoms associated with anxiety responding. We evaluated the psychometric properties and factor structure of the SAS in two large undergraduate samples who completed the SAS and measures of anxiety and depression. Exploratory factor analysis revealed four lower-order SAS factors in both samples: (1) anxiety and panic; (2) vestibular sensations; (3) somatic control; and, (4) gastrointestinal/muscular sensations. The SAS demonstrated good reliability in both samples, and the correlations between the SAS factors and other anxiety variables provide supportive evidence for convergent validity, though evidence for discriminant validity was limited. The strengths and limitations of the SAS are offered as well as the implications of our findings for the nature and assessment of somatic complaints in anxiety disorders.

We present a novel representation spatio-temporal graph (ST-Graph), in which: i) graph nodes express the motion primitives, each representing a short sequence of small-size patches over consecutive images; and ii) every two neighbor nodes are linked with either a positive edge or a negative edge to...
