The objectives of the present study were to adapt and analyze the factor structure, reliability, and validity of the Social Phobia and Anxiety Inventory for Children (SPAI-C; Beidel, Turner, & Morris, 1995) in a Spanish population. The SPAI-C was applied to a sample of 1588 children and adolescents with ages ranging from 10 to 17 years. The confirmatory factor analysis (CFA) showed a four-factor structure: Public performance, Assertiveness, Fear and avoidance/escape in social encounters, and Cognitive and psychophysiological interferences. Internal consistency was high (.90) and test-retest reliability was moderate (.56). Significant differences were found in the variables sex and age, although the effect size was small in both variables and their interaction. Overall, the increase of the age value was inversely proportional to that of social anxiety measured with the SPAI-C; in participants of the same age, values were higher for girls than for boys. Results suggest that the Social Phobia and Anxiety Inventory For Children is a valid and reliable instrument to assess social anxiety in Spanish children and adolescents.

The aim of this study was to examine the psychometric properties of the Brief version of the Fear of Negative Evaluation Scale – Straightforward Items (BFNE-S) in a non-clinical Spanish population. Rodebaugh et al. (2004) recommended the use of this scale composed of 8 straightforwardly-worded items, instead of the 12-item version of the BFNE. The sample consisted of 542 undergraduate students, 71.3% of whom were women and 28.7% were men; the mean age was 21.71 (4.78) years. Exploratory factor analysis produced one factor which accounted for 51.28% of variance. The internal consistency of the scale was α = .89. The BFNE-S correlated with the Social Avoidance and Distress Scale (r = .44), the Personal Report of Confidence as Speaker – Modified (r = .44), the Public Speaking Self-Efficacy Questionnaire (r = -.38) and both subscales of the Self-Statements during Public Speaking (SSPS-P r = -.22; SSPS-N r = .53). ANOVAs revealed significant differences in the BFNE-S amongst a non-clinical population, persons suffering from specific social phobia, non-generalized social phobia and generalized social phobia.

This study analyzed the relationship between social interaction styles and sociometric types in a sample of 1,349 (51.7% boys, and 48.3% girls) Spanish adolescents. The results revealed that the proportion of prosocial adolescents nominated as liked by peers was significantly higher than prosocial with social anxiety, whereas the proportion of aggressive adolescents nominated by peers as rejected was significantly higher than the proportion of rejected-prosocial and rejected-with social anxiety. The percentages of sociometric types and social interaction styles varied significantly according to gender and academic grade. Logistic regression analyses showed that being prosocial was 48% more likely when adolescents are nominated by peers as liked, whereas being prosocial was 41% and 79% less likely when adolescents were nominated as rejected and neglected, respectively. Furthermore, prosocial adolescents were 67% more likely nominated by peers as liked, and were less likely nominated as rejected (42%) and neglected (78%). Finally, being neglected was 83% more likely in aggressive adolescents.

The aim of this work was to update the validation of the Social Anxiety Screening Scale (SASS/EDAS) in a sample of Spanish adolescents. To achieve this, one study with a sample of 1489 students in secondary education, of ages 14 to 17 years, were carried out. The psychometric properties of EDAS were examined through confirmatory factor analysis, reliability (Cronbach's alpha), temporal stability (test-retest), and concurrent criterion validity. The results supported the three-independent-factor structure (avoidance, distress and interference), that showed best fit indices compared to alternative models. They also showed that the scores of participants on EDAS scales were reliable in terms of internal consistency (α > .80) and moderately reliable concerning temporal stability (r = .48-.60) over a five-week period. The correlations between the EDAS factors and other social anxiety measures were positive and significant. Data provide empirical evidence of the estimation of reliability and validity of this scale. Future work should extend the validation of the EDAS in clinical samples.

Availability of brief, self-report measures to be used as screening instruments is crucial to detect correctly youth with social anxiety disorder and therefore, reach those otherwise under-detected and under-treated. A previous study revealed that the Social Phobia Inventory (SPIN) was potentially an appropriate measure for screening social anxiety among US adolescents. However, there is a lack of information concerning its properties as a screening test in other cultures and languages. This is the main objective of this study, although further validity of the scale is provided as well. The sample consisted of 192 adolescents (a sample composed of 114 subjects with a principal diagnosis of social anxiety disorder; and a group consisting of 78 subjects with no diagnosis of social phobia). Results suggest that the Social Phobia Inventory has demonstrated good psychometric properties and indeed may be used as a screening tool in Spanish-speaking adolescents.

The aim of this study was to analyse the screening utility of the Social Anxiety Screening Scale (SASS/EDAS) in a sample of 227 adolescents with social anxiety disorder and 156 without it (14-17 years). Results showed that the EDAS subscales (Avoidance, Distress and Interference) scores were reliable in terms of internal consistency (α > .80). All the subscales discriminated between adolescents with and without the disorder. They also showed a positive and significant correlation with other empirically validated measures of social anxiety. The three subscales indicated relevant sensitivity (69.16-84.14%), specificity (63.46-66.03%) and areas under the curve (.74-.81%). Binary logistic regression analyses indicated the adequate predictive utility of EDAS subscales, with the Distress subscale as the best diagnostic predictor. The data provide empirical evidence of the usefulness of EDAS as a screener for adolescent social anxiety disorder in terms of reliability, convergent and discriminant validity, diagnostic accuracy and clinical usefulness.
