The Social Phobia and Social Interaction Anxiety Scales: Evaluation of Psychometric Properties

The present investigations examined the factor structure and psychometric properties of two new self-report measures of social phobia, the Social Interaction Anxiety Scale (SIAS) and the Social Phobia Scale (SPS). A confirmatory factor analysis in Study I provided support for the fit of a two-factor model of the SIAS and SPS. Internal consistency estimates were high for the original two scales with a sample of 200 undergraduates. Also, using an item parceling procedure, the obtained internal consistency reliability indices for each parcel were acceptable. Results of the CFA in Study II provided support for the factorial stability of the model identified in Study I. Furthermore, multisample analyses showed invariant patterns for factor loadings and factor correlations across 138 men and 272 women. Gender differences were not observed in the mean SIAS and SPS scale and item scores. Both scales correlated negatively and significantly with measures of social desirability. Concurrent validity was established for the scales. The SPS was less specific than the SIAS to symptoms of social phobia.     

Evaluation of the Psychometric Properties of a Measure of Child Irrationality

The article describes results from two studies that examined the psychometric properties of a measure of irrational thinking, the Child and Adolescent Scale of Irrationality (CASI), based on the model of REBT. Participants were 1034 children and parents recruited through schools and clinical settings. While the internal consistency of the total scale was quite high, the reliability of the proposed irrational subscales were considerably lower and an exploratory factor analysis failed to yield interpretable factors. Discriminative validity was demonstrated between subjects in clinical settings and school-based subjects on the total scale score and two of the irrational subscales. The total scale score and irrational subscales were correlated with ratings of behavior and emotion, with higher irrationality being correlated with higher levels of emotional and behavioral disturbance. Overall, while problems exist with the factor structure and reliability of the irrational subscales, the CASI appears to adequately measure irrational beliefs. Therefore, it may be clinically useful as a screener when working with children and adolescents.     

Investigating Psychometric Properties of Social Media Addiction Measures Among Adolescents

Assessment has a long history in counseling, with scholars noting multiple benefits to using assessment instruments in determining client strengths and needs as well as establishing relevant treatment goals. However, when counselors use unreliable or invalid instruments, they gather results that are ill equipped to inform clinical decision-making. Consequently, we evaluated and compared the psychometric properties of three scales of social media addiction—the Social Media Disorder Scale (van den Eijnden et al., 2016), the Bergen Social Media Addiction Scale (Andreassen et al., 2012, 2016), and the Social Media Addiction Scale (Al-Menayes, 2015)—to inform clinical use. Adolescents (N = 440) between the ages of 13 and 19 completed the scales. Results indicated that each scale provides a reliable and valid measurement of problematic social media use or addiction among adolescents. We provide recommendations for choosing a social media assessment and for future research.     

Distinction Between Well-Standardized Norms and the Psychometric Properties of a Measure

Funderburk and Eyberg (1989) described the psychometric properties of the Sutter-Eyberg Student Behavior Inventory (SESBI), a teacher rating scale of disruptive behaviors, for a sample of 55 preschool children. Additional data on the SESBI are presented for a sample of 60 preschool children. While both studies produced almost identical reliability and validity analyses, the scale score means are statistically and clinically different (i.e., a child in the clinical range in one study would be in the middle of the normal range in the other). These findings are used to emphasize the distinction between well-standardized norms and the psychometric properties of a measure. Suggestion are also made as to how behavioral assessment can more thoroughly attend to both of these properties of a measure.     

Psychometric Properties and Administration Measurement Invariance of Social Phobia Symptom Measures: Paper-Pencil vs. Internet Administrations

The psychometric properties of the online versions of assessment instruments for phobias and related symptoms were compared to those of paper-pencil versions. The examined measures were the Social Interaction Anxiety Scale (SIAS) and Social Phobia Scale (SPS). Students (n = 514) completed the instruments either in a paper-pencil in lab condition or an online at home condition. Means of the measures were largely equivalent between the two groups. Factor structures of the measures support construct validity of the two versions of the questionnaires. The coefficient alphas for the measures were reasonably high, ranging between .91 and .93 for both groups. Correlations between the measures were similar across groups. Overall, adequate psychometric properties of the online versions of the instruments were demonstrated, however, neither of the social phobia measures demonstrated measurement invariance between the two assessment modalities.     

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.     

Psychometric Evaluation of the Meaningful Life Measure

The 23-item Meaningful Life Measure (Morgan and Farsides 2008) comprises five subscales, each designed to assess a distinct component of personal meaning: purposeful life; valued life; accomplished life; principled life; and exciting life. In addition to providing a comprehensive composite meaning measure, this instrument presents the possibility of measuring these components separately in future research applications. To demonstrate the utility of their separate measurement, the present study therefore aimed to show differential patterns of correlation between these five subscales and meaning correlates identified in the literature. The MLM’s factor structure and internal reliability were replicated on the present sample. Evidence was then provided for the MLM’s convergent validity, and it was demonstrated that its five subscales were indeed differently predicted by the meaning correlates from the literature. Findings attest to the practical utility of a five-factor conceptualisation of meaning in life. In addition to identifying people who score low and high on different factors of meaning in life, the MLM facilitates the further investigation of specific antecedents and consequences of different meaning components.

Internet-Delivered CBT for Children with Specific Phobia: A Pilot Study

Background: Cognitive behavior therapy (CBT) has been shown to be an effective treatment for specific phobia in youth, but not all affected seek or receive treatment. Internet-delivered CBT could be a way to increase the availability of empirically supported treatments. Aims: An open trial was conducted to evaluate Internet-delivered CBT for children with specific phobia. Method: Children (N = 30) aged 8–12, and their parents, with a principal diagnosis of specific phobia were recruited through media advertisement. Participants received six weeks of Internet-delivered CBT with therapist support. The treatment was aimed for the parents and the children, with the first part being only for the parents. The primary outcome measure was the Clinician Severity Rating (CSR), and secondary measures included clinician-rated global functioning and child- and parent-reported anxiety and quality of life. All assessments were made at pretreatment, posttreatment, and three-month follow-up. Results: At posttreatment, there were significant reductions on the CSR, with a large within-group effect size (Cohen's d = 1.0) and 35% of children no longer meeting criteria for specific phobia. Self-report measures from parents and children showed significant effects on anxiety, with small to moderate effect sizes. Effects were maintained at three-month follow-up. Conclusions: Results show that Internet-delivered CBT with therapist support for children with specific phobia has the potential to reduce symptom severity. Randomized controlled trials are needed to further evaluate this treatment format.     

Psychometric Properties of the Survey of Personal Beliefs: A Rational-Emotive Measure of Irrational Thinking

A test of internal consistency and confirmatory factor analyses were performed on the Survey of Personal Beliefs, a new measure of irrational thinking based on rational-emotive personality theory. The survey, which was logically derived, includes a general rationality factor and subscales measuring five hypothesized core categories of irrational beliefs. Subjects included a nonclinical sample of 130 men and 150 women, with a mean age of 46. Results indicated that the Survey of Personal Beliefs had satisfactory total and scale reliability. The confirmatory analyses supported a higher order factor model including 5 first-order factors (awfulizing, self-directed shoulds, other-directed shoulds, low-frustration tolerance, and self-worth) and 1 second-order or general factor.     

Evaluating the Psychometric Properties of a Measure of Ethnic Identity Among Black South African Youth

The authors examined the dimensionality and psychometric properties of the Multigroup Ethnic Identity Measure (MEIM) among Black South African adolescents (ages = 13–14; 52% female) representing several ethnic groups (Ndebele, Pedi, Sotho, Swati, Tsonga, Tswana, Venda, Xhosa, Zulu) and evaluated the measure for differential item functioning primarily among four ethnic groups (Sotho, Tswana, Xhosa, and Zulu). Results indicated that a two-dimensional model best represented the data, reflecting ethnic search/clarity and ethnic affirmations. Subsequently, we evaluated the equivalence of the MEIM among the four South African ethnic groups and a sample of African American adolescents (M_age = 15.57 years; SD = 1.22; 51% female). Further analyses revealed that configural and metric models were excellent across the four South African ethnic groups and the African American group. However, scalar invariance (i.e., intercept) was not found; the item intercepts were different for the South African ethnic groups and African Americans. Findings are discussed with consideration for conducting research on ethnic identity among youth in South Africa.     

A Multivariate Genetic Analysis of Specific Phobia, Separation Anxiety and Social Phobia in Early Childhood

BACKGROUND: Comorbidity amongst anxiety disorders is very common in children as in adults and leads to considerable distress and impairment, yet is poorly understood. Multivariate genetic analyses can shed light on the origins of this comorbidity by revealing whether genetic or environmental risks for one disorder also influence another. We examined the genetic and environmental influences on the comorbidity between three common childhood anxiety disorders: Specific Phobia, Separation Anxiety and Social Phobia. METHODS: Using a two-phase design 4,662 twin-pairs were screened in the first phase and 854 pairs were assessed in the second phase by maternal-informant diagnostic interview using DSM-IV criteria. RESULTS: Multivariate genetic analysis revealed significant shared environmental over-lap between Specific Phobia and Separation Anxiety and significant familial and non-shared environmental over-lap between Specific Phobia and Social Phobia. CONCLUSIONS: Familial influences, especially shared environment, are central to the comorbidity between Specific Phobia and both Separation Anxiety and Social Phobia.     

Initial Psychometric Properties of a Brief Parent-Report Instrument for Assessing Tic Severity in Children with Chronic Tic Disorders

This article describes the development and initial psychometric properties of the Parent Tic Questionnaire (PTQ)—a new measure assessing the number, frequency, and intensity of motor and vocal tics in children and adolescents with Chronic Tic Disorder (CTD). Parents of 40 children with a CTD completed the PTQ as part of a larger assessment battery. Results show the PTQ to have excellent internal consistency and good to excellent 2-week test-retest reliability. The motor tic severity subscale, vocal tic severity subscale, and total severity score of the PTQ correlated highly with the corresponding scales of the gold-standard clinician-rated Yale Global Tic Severity Scale (YGTSS), indicating excellent convergent validity. Correlations between the YGTSS and PTQ remained strong after controlling for measures of obsessive-compulsive disorder and inattention, suggesting good discriminant validity. The PTQ is a promising supplement to current methods for assessing tic severity and further research on the validity, reliability, and clinical utility of the scale are warranted.     

Assessment of Emotional Avoidance in Adolescents: Psychometric Properties of a New Multidimensional Measure

Emotional avoidance—which includes cognitive and attentional processes that function as means of avoiding or dampening emotional experiences—may be a transdiagnostic risk and maintenance factor for emotional disorders. However, existing measures generally assess separate aspects of emotional avoidance, and few multidimensional measures exist for adolescents. The aim of the current study was to establish the psychometric properties of a new multidimensional measure of emotional avoidance for adolescents--the Emotional Avoidance Strategy Inventory for Adolescents (EASI-A; Fairholme et al. 2008)--employing an exploratory structural equation modeling framework. Analyses yielded a three-factor structure for the EASI-A, including subscales measuring Avoidance of Emotion Expression, Avoidance of Thoughts and Feelings, and Distraction. Moderate correlations were observed between the EASI-A and a measure of thought suppression, and the EASI-A was significantly associated with anxiety and depression symptoms. The EASI-A is a new, psychometrically sound measure that will aid in the assessment of avoidance as a vulnerability factor for psychopathology and as an outcome and mechanism for treatments of emotional disorders in adolescents.     

A New Measure of the Maladaptive Self-Beliefs in Social Anxiety: Psychometric Properties in a Non-Clinical Sample

Clark and Wells’ (1995) model of social phobia proposes that there are three types of maladaptive self-beliefs responsible for persistent social anxiety (high standard, conditional, and unconditional beliefs). Although these beliefs are theoretically important, there currently is not a validated measure of these beliefs in the social anxiety literature. Hence, the Self-Beliefs Related to Social Anxiety (SBSA) Scale was developed (Wong & Moulds, 2010a) and its psychometric properties were examined in the current study using a non-clinical sample (N = 600). Exploratory and confirmatory factor analyses ultimately indicated that a correlated three-factor solution optimally summarized the data with the three factors corresponding to the three belief types. The SBSA and its three subscales demonstrated good internal consistency and test-retest reliability, as well as convergent and divergent validity. The SBSA thus appears to have good psychometric properties and is appropriate for use in non-clinical samples. The potential applications of the SBSA and avenues for future research are discussed.     

Assessing the Structural and Psychometric Properties of a New Personality Measure for Use With Military Personnel in the French Armed Forces

We evaluated the measurement properties of a new personality scale for use with military personnel in the French Navy (N = 1,266). Principal components analyses indicated a five-factor structure assessing emotional stability, ascendancy, openness, agreeableness, and conscientiousness. Each factor comprised two facets that included 7 items per facet for a total of 70 items. Reliability analyses indicate that the factors and corresponding facets were internally consistent and temporally stable. Validity analyses indicate that the TAMI-P was significantly correlated with comparable measures of personality—correlations ranged from .53 to .68 with the Revised NEO Personality Inventory and the Big Five Questionnaire.     

Psychometric Properties of the HEXACO Personality Inventory

We introduce a personality inventory designed to measure six major dimensions of personality derived from lexical studies of personality structure. The HEXACO Personality Inventory (HEXACO-PI) consists of 24 facet-level personality trait scales that define the six personality factors named Honesty-Humility (H), Emotionality (E), Extraversion (X), Agreeableness (A), Conscientiousness (C), and Openness to Experience (O). In this validation study involving a sample of over 400 respondents, all HEXACO-PI scales showed high internal consistency reliabilities, conformed to the hypothesized six-factor structure, and showed adequate convergent validities with external variables. The HEXACO factor space, and the rotations of factors within that space, are discussed with reference to J. S. Wiggins' work on the circumplex.     

Psychometric Properties of the Parental Distress Subscale

Using data from the Fragile Family Child Wellbeing Study, we examined the psychometric properties of the parental distress subscale of the parenting stress index—short form. Unlike previous studies, we found that the two-factor model did not fit the data significantly better than the one-factor model. Moreover, the results indicated that both the one-factor and the two-factor models provided only a marginal fit to the data. This finding was consistent across two time periods. Implications of these findings and future research are discussed.
