Psychometric properties of the Spence Children's Anxiety Scale (SCAS) in Mainland Chinese children and adolescents

This study examined the psychometric properties of the Spence Children's Anxiety Scale (SCAS) in a Mainland Chinese community sample. The 38-item Chinese version of SCAS was administered to 1878 children and adolescents. Multiple group confirmatory factor analyses supported a common 6-factor model of SCAS for children and adolescents, and for boys and girls. The internal consistency and test-retest reliability of SCAS were satisfactory. Convergent and divergent validity of SCAS were supported by significant correlations with a measure of anxiety to a greater extent than with a measure of depression. Adolescents reported higher anxiety levels than children, and girls reported higher anxiety levels than boys. Compared to other studies, anxiety symptoms of Chinese children were found at a moderate level, but anxiety symptoms of Chinese adolescents were found at a high level. Our findings suggest that the SCAS is suitable for assessing anxiety symptoms in Mainland Chinese children and adolescents.     

Psychometric Properties of the Spence Children’s Anxiety Scale with Adolescents in Japanese High Schools

This study investigated anxiety symptoms of Japanese adolescents in community high schools. Japanese high school students (N = 1500) from diverse types of schools including general, vocational, and part-time schools completed the Spence Children’s Anxiety Scale (SCAS). First, confirmatory factor analysis supported the 6-factor structure with strong goodness-of-fit indices comparable with the original studies as well as those with Japanese elementary and junior high school students. Girls showed more anxiety symptoms, and items related to worry, insects/spiders phobia, checking, and fear of negative evaluations were the most common symptoms, similar to younger youth. Finally, students who attended part-time high school reported higher anxiety symptoms than those in full-time schools. The utility of the SCAS for assessment of anxiety symptoms in high school students and the need for preventive interventions for students at risk for developing anxiety were discussed.     

Psychometric Properties of the Spence Children’s Anxiety Scale (SCAS) in Cypriot Children and Adolescents

The Spence Children’s Anxiety Scale (SCAS) is a 38-item self-report questionnaire which measures symptoms of DSM-IV anxiety disorders in children and adolescents. This study examined the psychometric properties of the Greek translation of SCAS in a large community sample of children and adolescents (N = 1,072), aged 12–17 years, in the non-occupied territory of Cyprus. A subsample of these participants was retested 8 weeks after the initial assessment. The SCAS demonstrated high internal consistency (alpha = .92) and test–retest reliability (r = .88). The SCAS total scores correlated significantly with the anxious/depressed subscale of the Youth Self-Report, the Columbia Impairment Scale, and with the emotional subscale of the Strength and Difficulties Questionnaire. Confirmatory factor analyses revealed the same six-factor structure as the original SCAS. The SCAS proved to be a reliable and valid measure of anxiety symptoms in the Cypriot context.     

Psychometric properties of the Brazilian-Portuguese version of the Spence Children's Anxiety Scale (SCAS): Self- and parent-report versions

This study examined the psychometric properties of the Spence Children's Anxiety Scale (SCAS) self- and parent-report versions in a community (n = 712) and a clinical (n = 70) sample of Brazilian children and adolescents. Confirmatory factor analysis conducted in the community sample provided support to the original six correlated factors model of the SCAS. Moreover, the SCAS demonstrated good internal consistency, convergent and divergent validity, and a significant informant effect on the total score with higher anxiety levels in the self-report than in the parent-report version. Considering the clinical sample, we could demonstrate that the SCAS total scores have good discriminant validity differentiating: (a) anxious, community, and negative screening groups; and (b) children diagnosed with different severity levels of anxiety disorders. Our findings suggest that the SCAS (self- and parent-report versions) is suitable for assessing anxiety symptoms in Brazilian children and adolescents in community and clinical settings.     

Reliability and validity of the Spence Children's Anxiety Scale and the Screen for Child Anxiety Related Emotional Disorders in German children

The reliability and validity of the Spence Children's Anxiety Scale (SCAS) and the Screen for Child Anxiety Related Emotional Disorders (SCARED) were evaluated in a sample of 556 German primary school children. Both the SCAS (alpha = 0.92) and the SCARED (alpha = 0.91) were demonstrated to have high internal consistency. The validity of the SCAS and the SCARED was supported by a number of findings. First, in agreement with previous studies, girls displayed significantly higher levels of anxiety symptoms than boys. Furthermore, SCAS and SCARED scores were substantially interrelated. Finally, significant correlations were found between these two measures of anxiety symptoms and the Youth Self-Report and the Columbia Impairment Scale. The utility of the SCAS and the SCARED as screening instruments for anxiety symptoms in children is briefly discussed.     

DSM-IV-defined anxiety disorder symptoms in South African children

OBJECTIVE: To examine -defined anxiety disorder symptoms in a large sample of normal South African schoolchildren. METHOD: Children completed two self-report questionnaires: the Spence Children's Anxiety Scale (SCAS) and the 41-item version of the Screen for Child Anxiety Related Emotional Disorders (SCARED). RESULTS: Psychometric properties of the SCAS and the SCARED were moderate (convergent validity) to sufficient (reliability). Factor analyses yielded evidence for the presence of a number of hypothesized anxiety categories (i.e., social phobia, panic disorder, fears, and generalized anxiety disorder). Furthermore, anxiety levels of South African children were higher than those of Western (i.e., Dutch) children. Differences were found with regard to the content of prevalent anxiety symptoms among South African and Western children. CONCLUSION: Although psychometric properties of the SCAS and the SCARED in South African children somewhat deviated from those obtained in Western countries, both scales seem to be useful for assessing childhood anxiety symptoms in this country.     

Social phobia and separation anxiety symptoms in community and clinical samples of children and adolescents

OBJECTIVE: To examine the developmental progression and pattern of self-reported symptoms of social phobia (SP) and separation anxiety (SA) in community (n = 2,384) and clinical (n = 217) samples of children and adolescents, using a cross-sectional method. METHOD: Subjects were cross-classified by age, gender, and race. Using mean scores on the SP and SA subscales of the Multidimensional Anxiety Scale for Children, 4 categories of children were established: HighSP/HighSA, HighSP/LowSA, LowSP/HighSA, and LowSP/LowSA. Data were analyzed using a generalized logit model. RESULTS: Community sample: Preadolescents and females reported more symptoms of HighSP/HighSA and LowSP/HighSA than adolescents and males. White children reported more symptoms of HighSP/LowSA, while the opposite pattern was found among African-American children. Clinical sample: Similar to the community sample, preadolescents reported more symptoms of HighSP/HighSA. However, clinical males reported more symptoms of LowSP/HighSA than clinical females. CONCLUSIONS: In general, adolescents endorsed more symptoms of SP and fewer symptoms of SA than preadolescent children. Irrespective of age, white children endorsed more symptoms of SP and fewer symptoms of SA than African-American children. In the community sample, preadolescent boys endorsed more symptoms of SA and fewer symptoms of SP, suggesting a possible referral bias.     

Psychometric properties of the Spence Child Anxiety Scale with adolescents from five European countries

This study examined the factor structure, reliability, and validity of the original Spence Child Anxiety Scale (SCAS) and its four translations (German, Cypriot Greek, Swedish, Italian). A total of 2558 adolescents from five European countries (Germany = 495; Cyprus = 611; UK = 469; Sweden = 484; Italy = 499), ages 12-17 years, participated in the study. In addition to the SCAS, all participants completed the Strengths and Difficulties Questionnaire, a measure of general difficulties and positive attributes. The internal consistency and validity (convergent and discriminant) of the SCAS were excellent. Multiple group confirmatory factor analysis provided strong support for the generalizability of a 6-factor inter-correlated model across five European countries. Adolescents in the UK had significantly higher anxiety levels than adolescents in four other European countries. Our findings suggest that the SCAS is suitable for assessing anxiety disorder symptoms in adolescents in Germany, the UK, Cyprus, Sweden, and in Italy.     

The structure of anxiety symptoms among adolescents in Iran: A confirmatory factor analytic study of the Spence Children's Anxiety Scale

The present study examined the psychometric properties of the Iranian translation of the Spence Children's Anxiety Scale (SCAS) in a large community sample of adolescents (N = 1984), aged 12–17 years, in Ahvaz City, Iran. In addition to the SCAS, all participants completed the Strengths and Difficulties Questionnaire (SDQ), and the Centre for Epidemiological Studies Depression Scale for Children (CES-DC). The internal consistency (Cronbach Alpha = .92) and the validity of the Iranian translation of the SCAS was excellent. The SCAS total scores correlated significantly with the CES-DC, as well as with the emotional, conduct problems, hyperactivity-inattention, and peer problems subscales of the SDQ. However, Steiger's Z test demonstrated that correlations between the SCAS scores and the SDQ conduct problems or hyperactivity-inattention subscales were significantly lower than the correlations between the SCAS scores and the SDQ emotional symptoms subscale. Confirmatory factor analyses revealed the same 6-factor structure as the original SCAS. The SCAS proved to be a reliable and valid measure of anxiety symptoms among adolescents in Iran.     

Do non-referred young people with Autism Spectrum Disorders and their caregivers agree when reporting anxiety symptoms? A preliminary investigation using the Spence Children's Anxiety Scale

Anxiety difficulties and disorders are common in children and youth people with Autism Spectrum Disorders (ASD), but only a few studies have specifically examined informant agreement in non-referred samples. The present study examined informant agreement between 38 Singaporean caregiver–child dyads using the Spence Children's Anxiety Scale Parent Version (SCAS-P) and the SCAS Child self-report (SCAS-C) respectively. The young people with ASD (mean age 12 years 10 months) completed the SCAS-C, while their caregivers completed the SCAS-P, the Scales of Independent Behavior-Revised and the Developmental Behavior Checklist. There was overall moderately good agreement between caregivers and children's reporting of anxiety symptoms. Intra-class correlations were highest in the Separation Anxiety, Generalized Anxiety and Physical Injury subscales. Fourteen of the 38 SCAS items, most of which described overt anxiety symptoms, showed strong or moderate inter-rater agreement. Higher severity of autism symptoms was associated with poorer agreement in the Generalized Anxiety, Panic and Obsessions/Compulsions SCAS subscales. These preliminary findings suggest that the SCAS may be a useful measure for reporting anxiety symptoms in terms of satisfactory agreement between caregivers and young people in non-referred settings. Implications for screening for anxiety in non-referred young people with ASD are also discussed.     

Depressive Symptoms Among Children and Adolescents in Iran: A Confirmatory Factor Analytic Study of the Centre for Epidemiological Studies Depression Scale for Children

This study investigated the psychometric properties of the Iranian translation of the Centre for Epidemiological Studies Depression Scale for Children (CES-DC) in school children and adolescents in Iran. The CES-DC is a 20-item self-report scale designed to measure depressive symptoms in children and adolescents. A total of 1,984 children and adolescents, aged 12–17 years, participated in this research. In addition to the CES-DC, all participants completed the Spence Children’s Anxiety Scale (SCAS) and the Strength and Difficulties Questionnaire (SDQ). The CES-DC demonstrated high internal consistency (Cronbach Alpha = .87). Confirmatory factor analyses revealed the same four factor structure as proposed by Radloff. Invariance tests showed an equivalent structure among boys and girls and younger and older adolescents. The CES-DC total scores correlated significantly with the SCAS total scores and the SDQ emotional symptoms subscale, providing support of its convergent validity. To conclude, the CES-DC proved to be a reliable and valid measure of depressive symptoms in the Iranian context.     

Psychometric properties of the Spence Children's Anxiety Scale with young adolescents

The psychometric properties of the Spence Children's Anxiety Scale (SCAS) were examined with 875 adolescents aged 13 and 14 years. This self-report measure was designed to evaluate symptoms relating to separation anxiety, social phobia, obsessive-compulsive disorder, panic-agoraphobia, generalized anxiety, and fears of physical injury. Results of confirmatory and exploratory factor analyses supported six factors consistent with the hypothesized subtypes of anxiety. There was support also for a model in which the first-order factors loaded significantly on a single second-order factor of anxiety in general. The internal consistency of the total score and sub-scales was high, and 12-week test-retest reliability was satisfactory. The SCAS correlated strongly with a frequently used child self-report measure of anxiety and significantly, albeit at a lower level, with a measure of depression.     

Somatic symptoms in children and adolescents referred for emotional and behavioral disorders

Medically unexplained physical symptoms are frequently endorsed by children and adolescents in both clinical and community samples. The aim of this exploratory study is to examine the prevalence of somatic symptoms in a sample of 162 Italian children and adolescents consecutively referred to a Division of Child Neurology and Psychiatry from emotional and/or behavioral disorders. The role of age, gender, and psychiatric status was considered as a variable. Each patient received a DSM-IV assessment, including a diagnostic structured interview (DICA-R). The sample was divided according to gender (96 males, 66 females), age (70 children younger and 92 adolescents older than 12 years), and psychiatric diagnosis (Anxiety, Depression, Depression/Anxiety, Other). The presence of medically unexplained somatic symptoms was based on the responses to the DICA-R. Somatic complaints were reported in 69.2% of the patients. Headache was the most frequent somatic symptom (50.6%). Younger children showed higher rates of abdominal complaints than adolescents. No gender differences in frequency of somatic complaints were reported. Subjects with anxiety and/or depression reported significantly higher rates of somatic complaints, namely headache, than subjects with other mental disorders. No differences in frequency of somatic symptoms were evident between patients with anxiety, depression, and comorbid anxiety-depression. Our data suggest that an unexplained somatic symptom can be often considered as indicative of a neglected anxiety and/or depressive disorder. A collaboration between primary care physicians, pediatricians, and child psychiatrists may promote early diagnoses and timely treatments and prevent negative social and scholastic consequences.     

Maternal phobic anxiety and child anxiety

The present study examined the relation between maternal anxiety symptoms and child anxiety symptoms and evaluated whether a reporting bias is associated with maternal anxiety. Fifty-seven mother-child pairs participated. All children had features or diagnoses of separation anxiety disorder (SAD), generalized anxiety disorder, and/or social phobia. Measures of maternal symptomatology and child anxiety were administered. Higher levels of maternal phobic anxiety on the Brief Symptom Inventory were significantly associated with higher levels of separation anxiety in children. After controlling for clinician rating of SAD severity, maternal phobic anxiety emerged as a significant predictor of maternal ratings of child separation anxiety, accounting for 19% of the variance. Phobic mothers endorsed levels of separation anxiety in their children that exceeded levels endorsed by clinicians, suggesting maternal overreporting.     

Validation of the Spence Children's Anxiety Scale's obsessive compulsive subscale in a clinical and community sample

This study describes the validation of the obsessive compulsive subscale on the Spence Children's Anxiety Scale (SCAS OCD) for use as a clinical assessment tool. Data from 196 anxious children (102 males, ages 7-18) and their parent collected during a diagnostic assessment were compared to data from 420 children (206 males, ages 8-13) from the community collected by mail. The validity of the SCAS OCD parent- and child-report forms were supported by correlations with the Children's Yale-Brown Obsessive Compulsive Scale and continuous OCD symptom variables from the Anxiety Disorders Interview Schedule: Child Version. In addition, children with OCD were found to have higher scores on the SCAS OCD subscale than patients without OCD and children from the community without a reported anxiety diagnosis. The sensitivity of the SCAS OCD to treatment effects was also demonstrated in a subset of the clinical sample that received exposure and response prevention therapy. Finally, cut-scores were identified that examine the sensitivity and predictive utility of the scales.     

Normative Data on Anxiety Symptoms on the Multidimensional Anxiety Scale for Children in Taiwanese Children and Adolescents: Differences in Sex,Age, and Residence and Comparison with an American Sample

The aims of this study were to examine the differences in the levels of anxiety symptoms on the Taiwanese version of the Multidimensional Anxiety Scale for Children (MASC-T) between Taiwanese children and adolescents and the original American standardization sample across gender and age, and to examine differences in sex, age, and residential background in the levels of anxiety symptoms. A total of 10,566 Taiwanese children and adolescents in the community completed the MASC-T. Their levels of anxiety symptoms on the MASC-T were compared with the original American standardization sample in March’s study. The differences in age, sex and residential background in the levels of anxiety symptoms were examined by three-way analysis of variance (ANOVA). The results found significant differences in the levels of anxiety symptoms on nearly all MASC-T scales between Taiwanese and American children and adolescents across sex and age. Girls had higher levels of anxiety symptoms on all scales of the MASC-T than boys. Those from 16 to 19 years old had the higher levels of physical symptoms and social anxiety and the lower levels of harm avoidance and separation/panic than those in the 8–11 year- old and 12–15 year- old groups. Those who lived in rural areas had higher levels of physical symptoms and separation/panic than those who lived in urban areas. Those who lived in urban areas had a higher level of harm avoidance than those who lived in rural areas. These results provide fundamental knowledge on anxiety symptoms in Taiwanese children and adolescents. Further study is needed to examine the reasons for socio-cultural differences and differences in individual characteristics in anxiety symptoms.     

Anxiety in children with epilepsy

Although the prevalence is unknown, affective disorders are more common in children with epilepsy than in healthy controls. The purpose of the present study was to examine the occurrence of anxiety in children and adolescents with epilepsy and to determine factors associated with elevation of these symptoms. Children and adolescents (n=101) between the ages of 6 and 16 years were given the Revised Children's Manifest Anxiety Scale (RCMAS). Mild to moderate symptoms of anxiety were reported by 23% of the patients. Based on regression analysis, factors significantly associated with increased anxiety included the presence of comorbid learning or behavioral difficulties, ethnicity, and polytherapy. Results suggest the need to monitor children and adolescents with epilepsy for affective symptoms in order to provide appropriate interventions.     

Analysis of the interplay between depression,anxiety, and psychological resources in adolescence using self-report measures

Objective. Following recent literature which stresses the importance of broadening the conceptualization of mental functioning in youth, this paper aims to investigate structural relations between indicators of anxiety, depressive symptoms, and psychological resources in non-referred Italian adolescents, as captured by the Strengths and Difficulties Questionnaire (SDQ; ), the Spence Children's Anxiety Scale (SCAS; ) and the Children Depression Inventory (CDI; ). Methods. A hierarchical model which considers both the interplays and overlaps between these instruments is tested by means of Confirmatory Factor Analysis, in order to explore the possibility to use the three tools within a meaningful screening battery. First, validity and reliability of SDQ, SCAS, and CDI is successfully controlled thanks to three appropriate preliminary studies, an evidence not already acquired in the Italian context for the adolescent population. Then, the focal study devises and tests a model that merges indicators of the SDQ, SCAS, and CDI scales into four correlated factors, that is, Psychological Resources, Externalized behavior problems, Internalized Fear and Internalized Anxious Misery. Conclusions. Overall, findings corroborate the combined use of SDQ, SCAS, and CDI as a screening battery for the assessment of mental functioning in youth adopting a dimensional rather than a categorical approach.     

Spanish validation of the Spence Children's Anxiety Scale

The purpose of this study was to investigate the factorial structure and psychometric properties of the Spence Children’s Anxiety Scale (SCAS) in a sample of 1,708 Spanish children aged between 8 and 12 years. The SCAS was demonstrated to have satisfactory internal consistency with the Spanish sample, and factor analysis confirmed the six-factor original model. Convergent validity was supported by correlations with the State-Trait Anxiety Inventory for Children and the welfare dimension of the Child Health and Illness Profile-Children Edition. Low correlations between the SCAS and the Children’s Depression Inventory supported the divergent validity. Analysis suggested that anxiety scores decrease with age, and girls reported higher scores than boys. Overall, the SCAS was shown to have good psychometric properties for use with Spanish children by clinicians and researchers.     

Exploring the utility of the Spence Children's Anxiety Scales parent- and child-report forms in a North American sample

This study examined the psychometric properties of the Spence Children's Anxiety Scale child- and parent-report forms in a sample of 85 children from the community and 85 children with anxiety disorders matched on sex and age. Results indicated that both versions of the scale had good internal reliability, with the exception of the physical injury fears subscale. All subscales and the total scores of both versions discriminated children in the anxious group from community controls. Strong correlations between child and parent reports supported the concurrent validity of the measure. Furthermore, convergent and divergent validity of the scales were supported by significant correlations with negative affect and physiological hyperarousal to a greater extent than with positive affect indicating that SCAS and SCAS-P measured anxiety rather than depressive symptoms. Mean differences with research from other countries were apparent for selected subscales and supported the need for culture-specific norms.
