title: Psychometric properties of the state-trait inventory for cognitive and somatic anxiety (STICSA) in friendship dyads.
abstract: Recently, Gros, Antony, Simms, and McCabe (2007) demonstrated support for the psychometric properties of a new measure of state and trait anxiety, the State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA). In the present study, we further investigated the STICSA-Trait Version in 127 friendship dyads with a self-report from one participant (target) and an other-report of the target from a friend (informant). Consistent with previous research, confirmatory factor analyses supported the 2-factor structure of the STICSA-Trait in the target and informant reports. Moreover, the STICSA-Trait Cognitive and Somatic Anxiety subscales showed acceptable convergent and discriminant validity with related measures of anxiety. In addition, the STICSA-Trait subscales demonstrated adequate internal consistency and self-other agreement across the target and informant reports. Together, these findings provide additional support for the STICSA-Trait subscales as reliable and valid measures of cognitive and somatic anxiety.
