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.     

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.     

Self-Injurious Thoughts and Behaviors Interview: development, reliability, and validity in an adolescent sample

The authors developed the Self-Injurious Thoughts and Behaviors Interview (SITBI) and evaluated its psychometric properties. The SITBI is a structured interview that assesses the presence, frequency, and characteristics of a wide range of self-injurious thoughts and behaviors, including suicidal ideation, suicide plans, suicide gestures, suicide attempts, and nonsuicidal self-injury (NSSI). This initial study, based on the administration of the SITBI to 94 adolescents and young adults, suggested that the SITBI has strong interrater reliability (average kappa = .99, r = 1.0) and test-retest reliability (average kappa = .70, intraclass correlation coefficient = .44) over a 6-month period. Moreover, concurrent validity was demonstrated via strong correspondence between the SITBI and other measures of suicidal ideation (average kappa = .54), suicide attempt (kappa = .65), and NSSI (average kappa = .87). The authors concluded that the SITBI uniformly and comprehensively assesses a wide range of self-injury-related constructs and provides a new instrument that can be administered with relative ease in both research and clinical settings.     

The Social Phobia and Anxiety Inventory: Reliability and Validity in an Adolescent Spanish Population

The objective of this study is to examine the factor structure and psychometric properties of the SPAI in a sample of adolescent Spaniards. The results obtained support the use of the correlated two-factor SPAI subscales and indicate high coefficient alpha values for the SPAI subscales. The results provide support for the use of the SPAI in an adolescent population in a non-English-speaking country. Both exploratory and confirmatory factor analyses of the Social Phobia subscale showed a four-factor structure, instead of a five-factor dimension, as suggested by previous studies. Effects for gender and age and gender interaction were found. Limitations and suggestions for future research are discussed.     

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 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.     

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.     

Three traditional and three new childhood anxiety questionnaires: their reliability and validity in a normal adolescent sample

The current study examined the psychometrics of three traditional [i.e., the trait anxiety version of the State-Trait Anxiety Inventory for Children (STAIC), the Revised Children's Manifest Anxiety Scale (RCMAS), and the Fear Survey Schedule for Children - Revised (FSSC-R)] and three new childhood anxiety scales [the Multidimensional Anxiety Scale for Children (MASC), the Screen for Child Anxiety Related Emotional Disorders (SCARED), and the Spence Children's Anxiety Scale (SCAS)] in a large sample of normal adolescents (N=521). Childhood anxiety scales were generally found to be reliable in terms of internal consistency. Furthermore, evidence was obtained for the convergent and divergent validity of the various anxiety questionnaires. That is, anxiety questionnaire scores were found to be substantially intercorrelated. Particularly strong associations were found between total scores of the STAIC and the RCMAS, total scores of the SCARED and the SCAS, and between subscales that intend to measure specific categories of anxiety symptoms. Childhood anxiety questionnaires were substantially connected to an index of depression, although correlations among anxiety questionnaires were generally higher than those between anxiety scales and a measure of depression.     

Field reliability of comprehensive system scoring in an adolescent inpatient sample

The extent to which the Comprehensive System for the Rorschach is reliably scored has been a topic of some controversy. Although several studies have concluded it can be scored reliably in research settings, little is known about its reliability in field settings. This study evaluated the reliability of both response-level codes and protocol-level scores among 84 adolescent psychiatric inpatients in a clinical setting. Rorschachs were originally administered and scored for clinical purposes. Among response codes, 87% demonstrated acceptable reliability(> .60), and most coefficients exceeded .80. Results were similar for protocol-level scores, with only one score demonstrating less than adequate reliability. The findings are consistent with previous evidence, indicating reliable scoring is possible even in field settings.     

The psychometric properties of the Quality of Life Inventory in an Australian community sample

The Quality of Life Inventory (QOLI, Frisch) is an importance‐weighted measure of life satisfaction that has been found to possess adequate psychometric properties in US and clinically‐based samples. The current study aimed to investigate the normative distribution, factor structure and key psychometric properties of the QOLI in an Australian general community sample. Results indicated that the Australian sample (n = 259) reported slightly better quality of life than the US‐based standardisation sample. Confirmatory factor analyses showed that a three‐factor model provided the best fit for the data. Psychometric properties were all generally found to be adequate and close to Frisch's reported levels. In conclusion, this study indicated that the QOLI may be used in the Australian context with confidence. Future research could examine the clinical utility of the three‐factor model.     

The Narcissistic Personality Inventory: alternative form reliability and further evidence of construct validity

The aim of this study was twofold: (a)to measure the alternate form reliability of the Narcissistic Personality Inventory, and (b)to determine its construct validity by correlating it with the four scales of the Eysenck Personality Questionnaire (EPQ). The alternate form reliability was .72. The Extraversion and Psychoticism scales of the EPQ were positively and significantly correlated with the narcissism measure, and the Lie scale showed a significant negative correlation. The Neuroticism scale showed a nonsignificant relationship with narcissism. In addition, the combined Extraversion and Psychoticism scales produced[ a Multiple R with the narcissism measure that accounted for significantly more of the variance in narcissism than did either measure alone.     

An expanded childhood anxiety sensitivity index: its factor structure, reliability, and validity in a non-clinical adolescent sample

Anxiety sensitivity refers to the fear of anxiety-related bodily sensations that are interpreted as having potentially harmful somatic, psychological, or social consequences. The current study examined the factor analytic structure of anxiety sensitivity in a large sample of normal adolescents (N=518) using the revised childhood anxiety sensitivity index (CASI-R). Confirmatory factor analysis indicated that anxiety sensitivity as measured by the CASI-R can best be conceptualised as a hierarchical construct with four lower-order factors loading on a single higher-order factor. The lower-order factors were 'fear of cardiovascular symptoms', 'fear of publicly observable anxiety reactions', 'fear of cognitive dyscontrol', and 'fear of respiratory symptoms'. An additional aim of the present study was to investigate the psychometric properties of the CASI-R. Results showed the CASI-R to be a reliable scale in terms of internal consistency. Furthermore, CASI-R scores were substantially related to levels of anxiety sensitivity as measured by the original index, trait anxiety, symptoms of anxiety disorders, in particular 'panic disorder and agoraphobia', and depression. Finally, some evidence was found for the validity of the CASI-R factor scores. That is, all factors convincingly loaded on symptoms of 'panic disorder and agoraphobia', whereas the factor 'fear of publicly observable anxiety reactions' was also strongly associated with symptoms of 'social phobia'.     

Depression and Axis II symptomatology in an adolescent community sample: concurrent and longitudinal associations

The relationship between personality pathology and depression has been the focus of increasing attention, but few investigators have examined this issue prospectively or in adolescent community samples. The present study used both self report and interviewer assessments of personality disorder symptomatology and depression in a sample of 155 late adolescent women followed over three years. Personality pathology cluster and total scores demonstrated moderate to fairly high degrees of stability, indicating endurance of these traits in late adolescence. As predicted, Axis II symptoms were associated with concurrent depressive symptomatology. Overall, self-reported personality disorder symptoms, as well as those specifically in Clusters A and B, predicted interviewer-rated depression over two years beyond the contribution of initial depression, indicating that subclinical Axis II symptoms are a risk factor for subsequent depressive symptomatology.     

Test-retest reliability and construct validity of Contour Drawing Rating Scale scores in a sample of early adolescent girls

Test–retest and construct validity of Contour Drawing Rating Scale (CDRS) scores were examined in 1056 Grades 7 and 8 girls. Questionnaires were completed four times, including retests at 2, 6 and 14 weeks. Test–retest reliability for current size, ideal size and current–ideal discrepancy mostly exceeded 0.70 (0.65–0.87, for the full sample, with higher rs for shorter retest periods). Ideal and current size ratings increased slightly over time. High correlations between perceived current figure and measured body mass index; moderate rs between current–ideal discrepancy and body dissatisfaction and restrained eating; and very low or no significant correlations with social desirability supported construct validity in this group. The study supported the use of the CDRS in early adolescent girls.     

Development of a Brief Version of the Social Phobia Inventory Using Item Response Theory: The Mini-SPIN-R

The Social Phobia Inventory (SPIN) is a widely used measure in mental health settings and a 3-item version (mini-SPIN) has been developed as a screening instrument for social anxiety disorder. In the present study, we examined the psychometric properties of the SPIN and developed a brief version (mini-SPIN-R) designed to assess social anxiety severity using item response theory. Our sample included 569 individuals with social anxiety disorder who participated in 2 clinical trials and filled out a battery of self-report measures. Using a nonparametric kernel smoothing method we identified the most sensitive items of the SPIN. These 3 items comprised the mini-SPIN-R, which was found to have greater internal consistency, and to capture a greater range of symptoms compared to the mini-SPIN. The mini-SPIN-R evidenced superior convergent validity compared to the mini-SPIN and both measures had similar divergent validity. Thus, the mini-SPIN-R is a promising brief measure of social anxiety severity.     

Further exploration of the Vedic Personality Inventory: validity, reliability and generalizability

The purpose of this study was to explore the validity, reliability, and generalizability of the Vedic Personality Inventory which consists of constructs derived from the Vedic literature of India. There were 57 participants (20 men, 37 women). The mean age was 44.3 yr. (SD= 15.1). The sample was predominantly older, well-educated women who volunteered to participate as respondees to invitations to participate posted in supermarkets, churches, colleges, and on the internet. Analysis yielded statistically significant correlations for scores on the Vedic Personality Inventory and on the Daily Spiritual Experiences Scale and the Brief Symptom Inventory, each of which measures domains of interest addressed by the first inventory.
