A Confirmatory Comparison of the Factor Structure of the Children's Depression Inventory between European American and African American Youth

We examined the factor structure of the Children's Depression Inventory (CDI) among a sample of 523 African American children (m age = 12.76) and a sample of 564 European American youth (m age = 12.43). Previous investigations have produced discrepant factor structures among samples of predominantly majority-culture children, but fewer investigations of the factor structure of the CDI have been conducted among non-European American samples. Confirmatory factor analyses of the original 5 factors identified by Kovacs (1983, 1991) revealed that the items had invariant measurement properties across the samples. The latent factor structure, however, revealed telling differences between the two samples. For European American youth, only one of the original five factors was meaningfully differentiated from the others, whereas for the African American youth, two of the factors clearly emerged as unique facets of depression. Consistent with other reports, between-group mean differences on the CDI and its factors were noted. We argue that further validation of the CDI among traditionally underserved populations is warranted. Predictive validation investigations, in particular, are needed to examine the relationship between CDI factor scores and clinical outcomes.     

Assessing Measurement Invariance of the Children's Depression Inventory in Chinese and Italian Primary School Student Samples

This study tested the measurement invariance of Children's Depression Inventory (CDI) and compared its factorial variance/covariance and latent means among Chinese and Italian children. Multigroup confirmatory factor analysis of the original five factors identified by Kovacs revealed that full measurement invariance did not hold. Further analysis showed that 4 of 21 factor loadings, 14 of 26 intercepts, and 12 of 26 item errors were noninvariant. Factor variance and covariance invariant tests revealed significant differences between Chinese and Italian samples. The latent factor mean comparison suggested no significant difference across the two groups. Nevertheless, the finding of partial metric and scalar invariance suggested that observed mean differences on the CDI items cannot be fully explained by the mean differences in the latent factor. These results suggest that researchers and practitioners exercise caution when gauging the size of the true national population differences in depressive symptoms among Italian and Chinese children when assessed via CDI. In addition to providing needed evidence on the use of the CDI in Italian and Chinese children specifically, the methods used in this research can serve more generally as an example for other cross-cultural assessment research to test structural equivalence and measurement invariance of scales and to determine why it is important to do so.     

Dimensionality of the Children’s Depression Inventory: Meta-analysis of Pattern Matrices

This meta-analysis of 24 studies, comprising 35 independent samples with 18,099 participants, examined the factor structure of the Children’s Depression Inventory (CDI). The 5-factor solution involving Somatic Concerns, Externalizing, Negative Self-Concept, Lack of Personal and Social Interest, and Dysphoric Mood was supported for all samples. The 5-factor solution was appropriate for child, adolescent, general, at-risk/clinical, and English-speaking samples, whereas the 4-factor solution was the best for samples using non-English versions of the CDI. As the factor structure varied among study subgroups, the strength of relations between scale items and their underlying depressive symptoms varied. Hence, comparisons of mean CDI scores can be misleading.     

Examining the Factor Structure and Structural Invariance of the PANAS Across Children,Adolescents, and Young Adults

It is unclear what factor structure best represents the Positive and Negative Affect Schedule (PANAS) from childhood to adulthood. The PANAS structure was examined in a sample of 555 children (M age = 11.66, SD = 1.24), 608 adolescents (M age = 15.45, SD = 1.09), and 553 young adults (M age = 18.75, SD = 1.00). A partially invariant model consisting of Positive Affect, Fear, and Distress factors best represented the PANAS across all age groups, indicating that the underlying constructs are the same across age but that the factors become increasingly interrelated with increasing age.     

Symptoms of Post-Traumatic Stress Disorder in Bereaved Children and Adolescents: Factor Structure and Correlates

This study investigated the factor structure and correlates of posttraumatic stress-disorder (PTSD) symptoms among children and adolescents confronted with the death of a loved one. Three hundred thirty-two bereaved children and adolescents (aged 8–18; 56.9 % girls) who all received some form of psychosocial support after their loss, completed self-report measures of PTSD, together with measures tapping demographic and loss-related variables, depression, prolonged grief, and functional impairment. Parent-rated indices of impairment were also collected. We first evaluated the fit of six alternative models of the factor structure of PTSD symptoms, using confirmatory factor analyses. Outcomes showed that the 4-factor numbing model from King et al. (Psychological Assessment 10, 90–96, 1998), with distinct factors of reexperiencing, avoidance, emotional numbing, and hyperarousal fit the data best. Of all participants, 51.5 % met DSM-IV criteria for PTSD. PTSD-status and scores on the PTSD factors varied as a function of age and gender, but were unrelated to other demographic and loss-related variables. PTSD-status and scores on the PTSD factors were significantly associated symptom-levels of depression, prolonged grief, and functional impairment. Findings complement prior evidence that the DSM-IV model of the factor structure of PTSD symptoms may not represent the best conceptualization of these symptoms and highlight the importance of addressing PTSD symptoms in children and adolescents seeking help after bereavement.     

Factor structure of the Spanish version of the Spence Children Anxiety Scale (SCAS)

This paper presents the Spanish version of the Spence Children Anxiety Scale (SCAS), a rating scale for children and adolescents assessing anxiety disorders as they appear in the DSM-IV. SCAS scores were subjected to confirmatory factor analyses in a sample of 1671 children 10 to 17 years old. Results supported the proposed structure of six interrelated scales. This structure is completely invariant (except for means) in boys and girls and across age groups. Overall, girls scored slightly higher than boys. The relationship of SCAS scores with the child's age was nonexistent or very low and negative. The least frequent anxiety problems among children and adolescents were panic attacks and agoraphobia. Problems that most frequently presented extreme high scores were obsessive-compulsive disorder and social phobia. It is concluded that the Spanish version of the SCAS can confidently be used in the assessment of anxiety disorders in children.     

Measuring depression for Swedish nonclinical adolescents: Factorial validity and equivalence of the Beck Depression Inventory across gender

Building upon earlier confirmatory factor analytic research that validated a 2nd-order 4-factor structure of the Beck Depression Inventory for Canadian and Swedish nonclinical adolescents, the purposes of the present study were twofold: (a) to test the factorial structure of the Swedish version of the instrument separately for males ( n = 559) and females ( n = 537), and (b) to test for its measurement and structural equivalence across gender. Except for three minor discrepancies involving correlated errors, the hypothesized model best described the data for both males and females. Nonetheless, the imposition of equality constraints across sex revealed differences bearing on the measurement of six items, and latent construct relations involving the Somatic Elements factor. Four gender differences in factorial structure replicated findings for Canadian adolescents. Results have important implications for researchers, clinicians, and others whose interests focus on nonclinical adolescent depression.     

Norms and screening utility of the Dutch version of the Children's Depression Inventory in clinical and nonclinical youths

This study aimed to (a) assess relationships between the Children's Depression Inventory (CDI) and DSM-oriented depression and anxiety scales of the Youth Self Report, (b) develop reliable norms for the CDI, and (c) determine CDI cutoff scores for selecting youngsters at risk for depression and anxiety. A total of 3,073 nonclinical and 511 clinically referred children and adolescents from The Netherlands and Belgium were included. Results showed that CDI scores were significantly related to DSM-oriented symptoms of both depression and anxiety. CDI scores correlated highly with depression symptoms and moderately with anxiety symptoms. Norms for the CDI were determined by means of multiple regression analysis and depended on sex, age, and country. CDI cutoff scores for selecting individuals at risk for depression and anxiety as measured by the DSM-oriented depression and anxiety scales of the Youth Self Report were determined by means of multiple regression analysis and receiver operating characteristic analysis. A CDI score of 16 was found to have the most optimal balance between sensitivity and specificity for depression, whereas a score of 21 provided the best sensitivity and specificity for anxiety in a subsample of children. We conclude that the CDI is an effective instrument for screening depression and to a lesser extent anxiety in primary and secondary care centers, before applying further assessment of high-risk individuals.     

Revision and Restandardization of the Conners Teacher Rating Scale (CTRS-R): Factor Structure, Reliability, and Criterion Validity

The Conners Teacher Rating Scale (CTRS) is a commonly used research and clinical tool for assessing children's behavior in the classroom. The present study introduces the revised CTRS (CTRS-R) which improves on the original CTRS by (1) establishing normative data from a large, representative North American sample, (2) deriving a factor structure using advanced statistical techniques, and (3) updating the item content to reflect current conceptualizations of childhood disorders. Using confirmatory factor analysis, a six-factor structure was found which includes Hyperactivity-Impulsivity, Perfectionism, Inattention/Cognitive Problems, Social Problems, Oppositionality, and Anxious/Shy factors. The reliability of the scale, as measured by test-retest correlations and internal consistency, is generally satisfactory. Using all of the scale factors to discriminate between attention deficit hyperactivity disordered and normal children, 85 percent of children were correctly classified, supporting the validity of the scale and indicating excellent clinical utility. Similarities and differences between the original CTRS factor structure and the CTRS-R factor structure are discussed.     

Normative and reliability data for the children's depression inventory

The present study was undertaken to examine some of the psychometric properties of the Children's Depression Inventory (CDI), a self-report inventory devised by Kovacs and Beck (1977) to measure depression in children and adolescents. Normative and reliability data were obtained from three independent samples taken from eight public schools in central Pennsylvania. Age- and gender-related differences in reported characteristics of depression were also investigated. The subjects were 594 males and 658 females whose ages ranged from 8 to 16 years and whose combined mean age was 11.67 years (SD=1.91). The CDI was group-administered to all 1,252 subjects; 155 fifth-grade subjects (77 males and 78 females) were retested after 3 weeks, and 107 seventh- and eight-grade subjects (45 males and 62 females) were retested after 1 year. The distribution statistics for the combined samples yielded an overall CDI mean of 9.09, a standard deviation of 7.04, and a cutoff score of 19 for the upper 10% of the distribution. Reliability assessed through coefficient alpha, item-total score product-moment correlations, and test-retest coefficients proved acceptable. Gender differences were obtained for several item-total score correlations and for test-retest reliability of CDI scores.     

The longitudinal structure of the Children's Depression Inventory: testing a latent trait-state model

In a 6-wave longitudinal study, children (Grades 4-6, n = 648), adolescents (Grades 7-9, n = 1,489), and their parents completed child-adolescent or parent versions of the Children's Depression Inventory (CDI; M. Kovacs, 1981). Using structural equation modeling, the authors conducted latent trait-state analyses to distinguish between a stable trait dimension of depression (in which individual differences are stable over time) and an autoregressive dimension (in which individual differences are less stable over time). Children's CDIs reflected the autoregressive dimension more than a stable trait dimension, whereas parents' CDIs reflected a stable trait dimension more than an autoregressive dimension. Reports from adolescents and their parents reflected a stable trait dimension more than an autoregressive dimension of depressive symptoms. Results suggest that the longitudinal structure of the CDI varies considerably depending on the age of the target and the type of informant.     

Factor analytic evaluation of differences between black and caucasian emotionally disturbed children on the children's depression inventory

Scores on the Children's Depression Inventory (CDI) for 392 Caucasian and 159 black psychiatric inpatients between 6 and 18 years of age were subjected to principal-components factor extraction with Varimax rotation. Factors not contributing to variance were eliminated using the scree test (Cattell, 1966) and the degree of variance accounted for by remaining factors for both groups was examined through respective squared multiple correlations. A comparison of CDI factors for blacks and Caucasians indicated some differences, with blacks be ing less suicidal yet higher on other behavioral dimensions, such as oppositionality, and Caucasians higher on affective dimensions, such as sadness. The results support research on black-Caucasian differences and suggest the need to validate further the CDI with minority populations.     

Children's temperament in the US and China: similarities and differences

We report the results of research investigating temperamental characteristics of children in the People's Republic of China and the US using a parent-report instrument, the Children's Behavior Questionnaire (CBQ), defining temperament as individual differences in emotional, motoric, and attentional reactivity and self-regulation. Subjects were 624 6- to 7-year-old children, from Shanghai and the north-western region of the US. The 15 CBQ scales were factored for both samples, employing a principal axis factor analysis with an oblique rotation. Our findings indicated considerable similarity of factor structure in the two cultures, obtaining three factors labelled Surgency, Negative Affect, and Attentional Self-Regulation or Effortful Control. Differences across cultures were also found, with Surgency and Effortful Control scores being relatively higher than Negative Affect in the US sample and Negative Affect being relatively higher than Surgency and Effortful Control in the Chinese sample. Gender differences were also found to vary across cultures. Our findings are congruent with a view of underlying cultural similarities in temperamental variability across these cultures, influenced over time by the children's culturally varied experience.     

Age,gender, race,socioeconomic status,and birth cohort differences on the children's depression inventory: a meta-analysis

A within-scale meta-analysis was performed on 310 samples of children (ages 8-16; N = 61,424) responding to the Children's Depression Inventory (CDI). Girls' depression scores stayed steady from ages 8 to 11 and then increased between ages 12 and 16. Boys' CDI scores were stable from ages 8 to 16 except for a high CDI score at age 12. Girls' scores were slightly lower than boys' during childhood, but girls scored higher beginning at age 13. There were no socioeconomic status effects and no differences between White and Black samples. However, Hispanic samples scored significantly higher on the CDI. Analyses for birth cohort showed a slight decrease in boys' CDI scores over time and no change for girls. Longitudinal studies demonstrated a marked testing effect.     

Factor Structure and Construct Validity of the Dutch Version of the Antisocial Process Screening Device

The goal of the present study was to evaluate the factor structure and construct validity of the Antisocial Process Screening Device (APSD) in a community sample of Dutch adolescents. Confirmatory factor analyses supported the two- and three-factor model, but the two-factor model (Callous-Unemotional and Impulsivity/Conduct Problems) was more parsimonious. Model fit was invariant across gender. Interrater reliability was good and internal consistency of the factors was modest to good, with the exception of the Callous-Unemotional factor. Convergence with the APSD self-report version, divergence with the Big Five personality dimensions of Agreeableness and Conscientiousness, and expected gender differences in mean APSD scores reproduced findings obtained in American samples, supporting the cross-cultural validity of the APSD.     

Bayley‐III: Cultural differences and language scale validity in a Danish sample

The purpose of this study was to investigate cultural differences between Danish and American children at 2 and 3 years as measured with the developmental test Bayley‐III, and to investigate the Bayley‐III Language Scale validity. The Danish children (N = 43) were tested with the Bayley‐III and their parents completed an additional language questionnaire (the MacArthur‐Bates CDI). Results showed that scores from the Danish children did not differ significantly from the American norms on the Cognitive or Motor Scale, but the Danish sample scored significantly higher on the Language Scale. A comparison of the Bayley‐III Language subtests with the CDI showed that the two measures correlated significantly, but the percentile score from the CDI was significantly higher than the percentile score from the Bayley‐III Language subtests. This could be because the two instruments measure slightly different areas of language development, or because the Bayley‐III overestimates language development in Danish children. However, due to the limitations of the current study, further research is needed to clarify this issue.     

The role of children’s negative attributions on depressive symptoms: an inherited characteristic or a product of the early environment?

Negative attributional style has been associated with depressive symptoms in children. Yet, it is unclear whether these cognitive biases reflect inherited characteristics of the broader depressive phenotype or are a product of children's environments. While existing data in adolescents show that negative attributions reflect a genetic predisposition, elevating depressive responses to stress, other data suggest that negative attributions in children are more likely to reflect early environmental experiences on symptoms. Here, we assess the degree to which negative attributional style and depressive symptoms arise from common genetic, shared and non-shared environmental influences in childhood. Monozygotic and dizygotic twins reported on attributional style and depressive symptoms at age 8 (n = 300 pairs) and at age 10 (n = 250 pairs). Two multivariate models with varying assumptions on the nature of the relationship between negative attributions and depressive symptoms within and across time were fit to the data. The Common Pathway model provided better fit than the Cholesky decomposition. A common, latent factor influenced both attributional style and depressive symptoms at both time-points in children. The only significant influences on this factor were shared and non-shared aspects of the environment. Placing the present findings with those of adolescents suggests possible developmental differences in the relationship between attributional style and depressive symptoms.     

IRTs of the ABCs: children's letter name acquisition

We examined the developmental sequence of letter name knowledge acquisition by children from 2 to five years of age. Data from 2 samples representing diverse regions, ethnicity, and socioeconomic backgrounds (ns = 1074 and 500) were analyzed using item response theory (IRT) and differential item functioning techniques. Results from factor analyses indicated that letter name knowledge represented a unidimensional skill; IRT results yielded significant differences between letters in both difficulty and discrimination. Results also indicated an approximate developmental sequence in letter name learning for the simplest and most challenging to learn letters--but with no clear sequence between these extremes. Findings also suggested that children were most likely to first learn their first initial. We discuss implications for assessment and instruction.     

Refinement and Psychometric Properties of the Eight-Item Brazilian Positive and Negative Affective Schedule for Children (PANAS-C8)

This study aimed to refine the Brazilian Positive and Negative Affect Scale for Children (PANAS-C34). A total of 1,160 children, between seven and 16 years of age (M = 11.2; SD = 1.92), from public elementary schools in eight Brazilian southern cities participated in the study. Four studies were conducted for this project. Study I (n = 370) evaluated the factorial structure of the PANAS-C34 (the original 34-item version). Ten potential items were selected for the instrument’s refined version. Employing an independent sample (n = 340), Study II assessed the utility of this ten-item version. Exploratory factor analysis, parallel analysis, and confirmatory factor analysis supported a bi-factorial solution. However, significant modification indices emerged for two items (happy and sad) regarding their respective factors and thus they were excluded. In Study III, using another independent sample (n = 450), it was demonstrated that the eight-item version (PANAS-C8) had better fit indices than the ten-item version. In Study IV (N = 1,160) a multigroup confirmatory factor analysis was conducted to evaluate the measurement invariance of the factorial solution across gender. Moreover, convergent validity was also evaluated using the Child Depression Inventory (CDI) and the General Life Satisfaction Scale for Children (GLSS-C). Measurement invariance was obtained for the PANAS-C8 across all the investigated model parameters. The correlations between the PANAS-C8 and both the CDI and the GLSS-C were of similar magnitude to those obtained using the PANAS-C34. The PANAS-C8 had adequate validity indices, demonstrating its usefulness in evaluating positive and negative affect in children.     

The assessment of depression in children: The internal structure of the child depression inventory (CDI)

In the present report three separate studies of childhood depression were conducted. First, the internal structure of the Child Depression Inventory (CDI), with 216 children representing various ethnic groups with equal numbers of boys and girls, was evaluated through a factor analysis and by various internal-reliability measures (e.g. split-half reliabilities, Pearson correlations of each item to the total score). Four factors were established and internal reliability of the scale proved to be high. The relationship of the factor structure of the CDI to Kendell's Type A and B categorization of depression are discussed. In Study 2 the relationship of demographic variables to the CDI using the same group of children described for Study 1 was employed. Evaluating the characteristics of depression across age, sex and so on in children has not been frequently studied, and was deemed appropriate for the present investigation. Age proved to be a significant factor in depression scores although race and gender did not. With respect to age, older children tended to display more symptomatology. Comparisons of depressed children to nondepressed children also showed that age was a factor in the obtained scores, and range of severity in both groups. Depressed children differed from nondepressed children on all 27 items indicating that all the items on the CDI seem to be measuring a unitary concept. Study 3 compared CDI scores to a measure of social behavior, the Matson Evaluation of Social Skills with Youngster (MESSY). Seventy-six children (36 girls and 40 boys), ages 4–10 yrs $\text{(}\text{X}\text{?}\text{= 7)}$ were evaluated. Appropriate Social Skills was negatively correlated with childhood depression, and Inappropriate Impulsive/Assertiveness was positively correlated with depressive features described under the factor Guilt/Irritability. The implications of these data for further research on assessment, differential diagnosis and evaluation of treatment research are discussed.
