Psychometric Properties of the Social Phobia and Anxiety Inventory, the Social Anxiety Scale for Adolescents, the Fear of Negative Evaluation Scale, and the Social Avoidance and Distress Scale in an Adolescent Spanish-Speaking Sample

The relationship among several social anxiety measures and a semistructured interview in an adolescent Spanish-speaking sample is examined. Construct validity and test-retest reliability were tested. A principal axis factor analysis was also explored. Results revealed good construct validity and alpha coefficients for the assessment instruments such as the Social Phobia and Anxiety Inventory (SPAI), the Social Anxiety Scale for Adolescents (SAS-A), the Fear of Negative Evaluation Scale (FNES) and the Social Avoidance Distress Scale (SADS). Among these, data strongly support the validity of the Social Phobia and Difference measures of the SPAI and Total SAS-A score as assessment measures in the adolescent population even in non-American cultures and languages. Furthermore, results appear to support the presence of a single higher-order dimension, social anxiety, as measured by the instruments used in this study.     

Validity of the social avoidance and distress and fear of negative evaluation scales

The Social Avoidance and Distress Scale (SAD) and the Fear of Negative Evaluation Scale (FNE), two commonly accepted measures of social anxiety, were administered to a large group of patients diagnosed as having Agoraphobia with Panic Attacks, Agoraphobia without Panic Attacks, Social Phobia, Simple Phobia, Generalized Anxiety Disorder, Panic Disorder and Obsessive-Compulsive Disorder. On the SAD and FNE, social phobies did not differ significantly from the other major anxiety disorders, with the exception of simple phobies. Performance on the SAD and FNE was significantly correlated with measures of anxiety, depression and general emotional distress. The lack of discriminative validity of the SAD and FNE is discussed.     

Concurrent validity of the Social Phobia and Anxiety Inventory

The Social Phobia and Anxiety Inventory (SPAI) is a new instrument designed to assess symptoms of social phobia. Although the scale has been shown to have a good test-retest reliability, internal consistency, and construct validity, no studies have examined its concurrent validity with respect to other measures of social anxiety and avoidance. In the present study, the relationship between the SPAI and several self-report measures of social anxiety was examined in a sample of 23 patients meeting DSM-III-R criteria for social phobia. The relationship between the SPAI and other measures of psychopathology, as well as performance during a role play test and an impromptu speech, was also examined. The results strongly support the concurrent validity and the specificity of the SPAI. The Social Phobia subscale may be a better index of social anxiety symptoms than the Difference subscale.This research was supported, in part, by NIMH grants MH 38636 and MH 41577 to the second author.     

Psychometric properties of the Social Phobia and Anxiety Inventory for Children in a Spanish sample

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.     

An Assessment of Social Phobia and Social Anxiety and their Relation to Self-Consciousness

Abstract

The translation of the Social Phobia and Anxiety Inventory (SPAI) into Icelandic was submitted to a psychometric assessment. Two hundred sixty-three university students participated in the study. In addition to the SPAI they filled in Fenigstein, Scheier and Buss' (1975) Self-Consciousness Scale (SCS) as well as Spielberger's (1983) State-Trait Anxiety Inventory (STAI). A principal components analysis of the SPAI yielded as expected an agoraphobia and a social phobia factor. As expected the Social Anxiety Scale of the SCS correlated much more strongly with the Social Phobia than the Agoraphobia Scale. The correlation of the Social Phobia Scale with the Social Anxiety Scale was substantially higher than its correlation with any other anxiety measure. The relationships between the Social Phobia Scale and Public versus Private Self-Consciousness were moreover in accordance with theoretical expectations as well as prior research. Generally the discriminant and convergent validity of the Icelandic translation of the Social Phobia Scale as a measure of social anxiety is supported.     

The Social Phobia Inventory: screening and cross-cultural validation in Spanish adolescents

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.     

Psychometric properties of the social phobia inventory: further evaluation

This study investigated the psychometric properties of the Social Phobia Inventory [SPIN; Connor, K. M., Davidson, J. R. T., Churchill, L. E., Sherwood, A., Foa, E., Wesler, R.H., 2000. Psychometric properties of the Social Phobia Inventory (SPIN). British Journal of Psychiatry, 176, 379-386], a measure of severity in social phobia (social anxiety disorder). Participants included 132 participants with social phobia, 57 participants with panic disorder and agoraphobia (PDA), and 62 participants with obsessive-compulsive disorder (OCD). Confirming findings from an initial validation study, the SPIN was found to have excellent internal consistency and good test-retest reliability. It also distinguished well between those with social phobia and those with either PDA or OCD. Good convergent and discriminant validity were established by examining correlations with other conceptually related and unrelated scales. Finally, the SPIN was sensitive to changes in social phobia severity following cognitive behavioral group treatment. In conclusion, the SPIN is both reliable and valid for the measurement of social phobia severity and outcome following psychological treatment.     

The social phobia and anxiety inventory: Further validation in two nonclinical samples

The Social Phobia and Anxiety Inventory (SPAI) has been developed to assess specific symptoms of social phobia and agoraphobia. Although the SPAI was developed with both clinical and nonclinical populations, research with this measure is currently focused primarily on clinical samples. We examined the factor structure and psychometric properties of the SPAI in adult community and college undergraduate samples. We found that single-sample and multisample confirmatory factor analyses provided support for extending use of the correlated two-factor SPAI subscales to our nonclinical samples. In addition, we found evidence for the internal consistency reliability of the SPAI subscales in both samples. Limitations and suggestions for future research are discussed.     

Peer victimization and social anxiety in adolescence: a prospective study

This study reports a one‐year prospective investigation of the relations between overt and relational victimization and social anxiety and phobia in a sample of adolescents. The Social Experience Questionnaire—Self Report Form (SEQ‐S), Social Anxiety Scale for Adolescents (SAS‐A), and Social Phobia and Anxiety Inventory for Children (SPAI‐C) were administered to 144 ninth grade adolescents. A follow‐up assessment with the SEQ‐S, SAS‐A, and SPAI‐C was conducted one year later. Results indicated that relational victimization predicted symptoms of social phobia but not general social anxiety and avoidance one year later. Overt victimization was not a significant predictor of social anxiety and phobia one year later. Social anxiety and phobia did not predict peer victimization one year later. However, increases in social anxiety and social phobia symptoms (for boys) over time were positively associated with increases in relational victimization over time. Implications of these findings for peer victimization and social anxiety in the development of social phobia and negative peer experiences are discussed. Aggr.

Development of an abbreviated Social Phobia and Anxiety Inventory (SPAI) using item response theory: the SPAI-23

An abbreviated version of the Social Phobia and Anxiety Inventory (SPAI) was developed using methods based in nonparametric item response theory. Participants included a nonclinical sample of 1,482 undergraduates (52% female, mean age = 19.4 years) as well as a clinical sample of 105 individuals (56% female, mean age = 36.4 years) diagnosed with either generalized (73%) or specific social phobia (27%). Twenty-three of the 45 SPAI items demonstrated good discrimination along the social anxiety continuum. In addition, option characteristic curves (OCCs) indicated that the SPAI's 7-point scale may generate errors in ranking individuals. Thus, options were collapsed to improve item performance. No gender differences emerged between any of the items' OCCs, suggesting that items function similarly among men and women. The abbreviated version also correlated highly with the original 45-item SPAI and exhibited similar patterns of correlations with measures of social anxiety. The SPAI-23 has considerable practical benefits, including a screening of both social and agoraphobic anxiety as well as decreased assessment and scoring time.     

Self-focused attention before and after treatment of social phobia

It has been hypothesized that effective psychological treatment for social phobia changes the person's representation of the self in a more positive direction. In order to test this hypothesis, we analyzed 506 thoughts that were endorsed by 23 social phobic individuals while anticipating socially stressful situations before and after exposure therapy. Treatment efficacy was assessed with the Social Phobia and Anxiety Inventory (SPAI) [Turner, S. M., Beidel, D. C., Dancu, C. V., & Stanley M. A. (1989) An empirically derived inventory to measure social fears and anxiety: the Social Phobia and Anxiety Inventory. Psychological Assessment, 1, 35-40)]. Subjects endorsed significantly fewer negative self-focused thoughts after treatment (on average 8.7% of the thoughts) than before treatment (26.5%, p < 0.005). These changes were highly correlated with pre-post difference scores in the social phobia subscale of the SPAI (r = 0.74, p < 0.0001). Implications of the results for the cognitive model of social phobia will be discussed.

Effectiveness of treatments for social phobia in an applied field

Social phobia is one of the most common disorders and one that requires the most attention from psychological clinics. The aim of this article was to study the effectiveness of psychological treatments in a University Psychological Clinic. Seventy-one social phobia patients requested psychological assistance. The average number of assessment sessions was 3.8 and the average number of treatment sessions was 16.1. Therapeutic success reached 64.2%, withdrawal percentage was 11.3%, and drop-out percentage was 24.5%. The effect size (Cohen's d) achieved in the Social Avoidance and Distress Scale (SAD) and Fear of Negative Evaluation Scale (FNE) were 1.96 and 1.78, respectively. Comparing these results with efficacy research (particularly meta-analysis), it has been shown that the treatment effectiveness achieved is very similar. It is concluded that cognitive behavioural treatments for social phobia can be transferred from research settings to clinical practice.     

Validity of Two Questionnaires to Assess Social Fears: The Dutch Social Phobia and Anxiety Inventory and the Blushing, Trembling and Sweating Questionnaire

This report evaluates some psychometric properties of the Dutch Social Phobia and Anxiety Inventory (SPAI-N) as well as a newly developed instrument to assess fear of showing somatic symptoms among social phobic, the Blushing, Trembling and Sweating Questionnaire (BTS-Q). Results support the reliability and discriminative validity of the Dutch SPAI and the BTS-Q. Both questionnaires are able to discriminate social phobics from a community sample. Social phobics with fear of blushing, trembling, and sweating as the main complaint could be discriminated from social phobics without fear of blushing, trembling, and sweating as the main complaint using the BTS-Q. In contrast with expectations derived from cognitive models of social phobia, social phobics with fear of blushing, trembling, and sweating did not have stronger dysfunctional beliefs about (the social consequences of) blushing, trembling, and sweating than social phobics without such fears.     

The social phobia and anxiety inventory: Construct validity

The Social Phobia and Anxiety Inventory (SPAI) is a new instrument composed of social phobia and agoraphobia subscales. The latter scale is used to detect social anxiety that may result from agoraphobia. The SPAI's construct validity was assessed through several procedures. First, confirmatory factor analyses were conducted to validate the existence of the two subscales. Second, exploratory factor analyses examined the underlying structure of the social phobia subscale. Third, a Q factor procedure determined if different anxiety diagnostic groups could be differentiated by their SPAI response pattern. The results confirmed the utility of the two SPAI subscales and identified a number of dimensions contained within the social phobia subscale which differed depending upon the specific subject sample. In addition, the complaints of social phobies appeared more homogeneous than those of an agoraphobic comparison group. The results are discussed in terms of construct validity and the sensitivity of the SPAI to various dimensions of social phobia fears.This study was supported in part by NIMH Grants 41852, 30915, 18269, and 16884.     

The Reliability,Validity, Discriminant and Predictive Properties of the Social Phobia Inventory (SoPhI)

This paper reports on the psychometric properties of the Social Phobic Inventory (SoPhI) a 21-item scale that was designed to measure social anxiety according to the criteria of DSM-IV (American Psychiatric Association, APA (1994) Diagnostic and Statistical Manual of Mental Disorder , 4th Edn., Washington). Factor analysis of the SoPhI using data from a clinical sample of respondents with social phobia revealed one factor which explained approximately 59% of variance and which demonstrated strong internal reliability ( f = 0.93). The SoPhI demonstrated concurrent validity with the SPAI ( r = 0.86) and convergent validity with the Fear of Negative Evaluations-Revised ( r = 0.68). The predictive utility of the scale was demonstrated in a sample of university students classified as extroverted, normal, shy/introverted, and phobic/withdrawn ( m 2 57%). Multivariate Analysis of Variance (MANOVA) revealed that the combined university sample differed from the clinical sample on the summated scores on the SoPhI and that 43% ( m 2 ) of this difference was attributable to group membership. This figure rose to 58% attributable to group membership when these same groups were compared for differences on the 21 individual items. Scores of the SoPhI that are indicative of concern and of possible diagnostic criteria, as well as suggestions for future research, are discussed.     

Psychometric comparability of English- and Spanish-language measures of anxiety and related affective symptoms

An array of measures of anxiety and related disorders (viz., Albany Panic and Phobia Questionnaire; Anxiety Sensitivity Index; Beck Anxiety Inventory; Beck Depression Inventory-II; Body Sensation Questionnaire; Fear Questionnaire; Padua Inventory; Penn State Worry Questionnaire; Post-Traumatic Stress Disorder Diagnostic Scale; Social Interaction Anxiety Inventory; and Worry Scale) was edited or translated from English into Spanish. Following an extensive edit and translation process, bilingual participants (n = 98) were assessed with the English and Spanish versions of these measures. Coefficient alphas were excellent and comparable across language versions. Means and standard deviations were also comparable across language versions. Evidence of convergent and discriminant validity was found for both language versions. The two language versions of each measure correlated highly with each other. This psychometric comparability adds confidence in using the newly edited or translated Spanish language measures in clinical practice and research.     

The Social Phobia and Anxiety Inventory: concurrent validity with a clinic sample

The Social Phobia and Anxiety Inventory (SPAI) is an empirically derived self-report inventory developed as a specific measure of social phobia. The current investigation included two studies. The first examined the correlation of the SPAI with daily social behavior of a clinic sample of social phobics. The results indicated that the SPAI provides a reasonable indication of the distress experienced during daily social encounters in three dimensions: behavior, cognitions, and overall distress. The second study examined the validity of the SPAI with reference to the somatic response and avoidance behavior of social phobics. The results indicated that the somatic items of the SPAI are related to the somatic response of social phobics and that performance on the SPAI is associated with avoidance behavior in an anxiety-producing task.     

Development of a short form Social Interaction Anxiety (SIAS) and Social Phobia Scale (SPS) using nonparametric item response theory: the SIAS-6 and the SPS-6

Shortened forms of the Social Interaction Anxiety Scale (SIAS) and the Social Phobia Scale (SPS) were developed using nonparametric item response theory methods. Using data from socially phobic participants enrolled in 5 treatment trials (N = 456), 2 six-item scales (the SIAS-6 and the SPS-6) were developed. The validity of the scores on the SIAS-6 and the SPS-6 was then tested using traditional methods for their convergent validity in an independent clinical sample and a student sample, as well as for their sensitivity to change and diagnostic sensitivity in the clinical sample. The scores on the SIAS-6 and the SPS-6 correlated as well as the scores on the original SIAS and SPS, with scores on measures of related constructs, discriminated well between those with and without a diagnosis of social phobia, providing cutoffs for diagnosis and were as sensitive to measuring change associated with treatment as were the SIAS and SPS. Together, the SIAS-6 and the SPS-6 appear to be an efficient method of measuring symptoms of social phobia and provide a brief screening tool.     

Discriminant validity of the Social Phobia and Anxiety Inventory (SPAI), the Social Phobia Scale (SPS) and the Social Interaction Anxiety Scale (SIAS)

Three measures commonly used in assessment of social phobia, the Social Phobia and Anxiety Inventory (SPAI [Turner, S. M., Beidel, D. C. & Dancu, C. V. (1996). Social phobia and anxiety inventory: manual. Toronto, Ont.: Multi-Health Systems Inc.), the Social Phobia Scale (SPS [Mattick, R. P. & Clarke, J. C. (1998). Development and validation of measures of social phobia scrutiny fear and social interaction anxiety. Behaviour Research and Therapy, 36, 455-470] and the Social Interaction Anxiety Scale (SIAS [Mattick, R. P. & Clarke, J. C. (1998). Development and validation of measures of social phobia scrutiny fear and social interaction anxiety. Behaviour Research and Therapy, 36, 455-470], were compared for their ability to discriminate between social phobia and other anxiety disorders (panic disorder with or without agoraphobia). Participants were 117 patients attending a specialized anxiety disorders unit for treatment. While all three measures were able to detect differences between social phobic patients and patients with panic disorder with or without agoraphobia, a logistic regression analysis showed that the SPAI, but not the SPS and SIAS, was a significant predictor of membership of the social phobia group. Receiver operating characteristic (ROC) analysis also showed that the SPAI was the better measure for discriminating between social phobia and panic disorder with and without agoraphobia. Analysis of the sensitivity, specificity and positive and negative predictive power of the measures at the optimum cutoff scores produced by the ROC analysis are presented.
