Psychometric properties of the Social Interaction Anxiety Scale and separation criterion between Spanish youths with and without subtypes of social anxiety

Social Anxiety Scale for Adolescents: Factorial invariance and latent mean differences across gender and age in Spanish adolescents

“…Although increasing attention has been given to the assessment of social anxiety in adolescence (see García-López, Piqueras et al, 2008;Kearney, 2005) very little is known about cross-gender and cross-age equivalence in the expression of social anxiety among adolescents. This gap in knowledge is of great concern because social anxiety disorder is one of the most common emotional disorders among adolescents in Spain (e.g., Inglés, Martínez-Monteagudo et al, 2008;Zubeidat et al, 2007) and in other European countries such as Germany (e.g., Beesdo et al, 2007), Norway (Van Roy, Kristensen, Groholt, &Clench-Aas, 2009), andSweden (e.g., Gren-Landell et al, 2009), as well as in the U.S. (e.g., Hayward et al, 2008).…”

“…In recent years, increasing attention has been given to selfreport measures of social anxiety in adolescence (e.g., García-López, Hidalgo, Beidel, Olivares, & Turner, 2008;Storch et al, 2006;Viana, Rabian, & Beidel, 2008;Zubeidat, Salinas, Sierra, & Fernández-Parra, 2007). Recent reviews conducted in Spain (García-López, Piqueras, Díaz-Castella, and the US (Kearney, 2005) have concluded that one of the most pertinent and empirically supported measures of social anxiety in adolescence is the Social Anxiety Scale for Adolescents (SAS-A; La Greca, 1999;La Greca & Lopez, 1998).…”

Dimensional structure of the Social Interaction Anxiety Scale according to the analysis of data obtained with a German version

“…These authors did not explore the factor structure of the 17 positively keyed SIAS items. Instead they apparently presupposed their homogeneity although previous studies suggested that they might be influenced by more than one factor (Safren et al, 1998;Zubeidat et al, 2007). Thus, in addition we will also address the still open question of the dimensional structure of the 17 positively keyed SIAS items.…”

“…About one third of the studies investigating the dimensional structure of the SIAS reported that they form a separate factor (see Table 1) while according to other studies only one factor underlies the answers to all 20 SIAS items (Mattick & Clarke, 1998;Olivares et al, 2001). Zubeidat, Salinas, Sierra, and Fernández-Parra (2007) identified even three SIAS factors. One of them was associated primarily with the three negatively and one of the positively keyed items, and the two others each with a subset of the remaining 16 positively keyed items.…”

Exploration of the psychometric characteristics of the Liebowitz Social Anxiety Scale in a Spanish adolescent sample

“…After carrying out the confirmatory factor analyses, all the items of the SIAS were saturated in a single factor called Interaction Social Anxiety. Recently, Zubeidat et al [2007b] reported that the SIAS has three factors, with the first two explaining 41.62% of the variance and presenting internal consistency coefficients of .88 and .52, respectively.…”
