Anxiety and Depression in Children and Adolescents: A Factor-Analytic Examination of the Tripartite Model

The tripartite model of Clark and Watson (1981) suggests that the oft-observed covariation between anxiety and depression can best be understood by examining three related yet distinct constructs: negative affectivity, positive affectivity, and elevated physiological arousal. In the present study, 510 boys and girls in the 4th, 7th, and 10th grades completed the Children's Depression Inventory and the Revised Children's Manifest Anxiety Scale. Confirmatory factor analyses were conducted to determine the goodness of fit of single-factor (i.e., negative affectivity), two-factor (i.e., anxiety and depression), and three-factor models (i.e., negative affectivity, positive affectivity, and physiological arousal). Analyses were conducted by examining each of the models in the whole sample first and then separately for boys and girls and for fourth, seventh, and tenth grade youths. Results failed to support the tripartite theory; rather, the findings supported a two-factor model in all cases. These factors represented the general constructs of anxiety and depression, and these factors remained significantly interrelated. Consistent with previous findings, the strength of these relations was stronger for boys than girls and for children than adolescents.     

Dimensionality and correlates of problem solving: the use of the Problem Solving Inventory in the Chinese context.

The dimensional structure of the Problem Solving Inventory (PSI) was investigated using data collected from a sample of 499 Chinese university students in teacher training. While the original three-factor model provided poor fit to the data, the revised two-factor model provided more adequate fit but failed to consider a PSI construct tapped in the original PSI formulation. The newly constructed PSI scales based on the present data provided viable alternative scales reflecting constructs of self-efficacy, rational coping and dysfunctional coping. These newly developed problem-solving scales were predictive of indices of psychological adjustment in terms of depression, burnout, and perceived self-efficacy toward helping others. The use of the PSI in the Chinese context is discussed.     

The construct validity of burnout

Considerable confusion exists in the burnout literature about the similarities and separateness among the constructs of burnout, depression and job satisfaction. This study examined the construct validity of burnout using Campbell & Fiske's multitrait-multimethod approach. The constructs of burnout, depression and orderliness (chosen as a discriminant construct) were assessed by three types of self-report instruments. Data were analysed for 181 females and 139 male faculty members who spent at least 50 per cent of their time in teaching. Results indicated that measures of burnout largely met Campbell & Fiske's criteria for construct validity: burnout measures possessed adequate to good internal reliability and convergent validity. However, burnout measures also correlated substantially with measures of depression. Results are discussed in terms of possible explanations for the substantial overlap that has been demonstrated among measures of burnout, depression and job satisfaction.     

Chronic, low-grade depression in a nonclinical sample: depressive personality or dysthymia?

Depressive personality disorder (DPD) is being considered for inclusion in future editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM). However, there is substantial conceptual and empirical overlap between DPD and dysthymic disorder (Dysthymia) criteria, suggesting that these two constructs may not be distinct. Confirmatory factor analysis of the DPD traits and dysthymia symptoms in a large, nonclinical sample (N = 368) indicated that a two-factor model was a better fit than a one-factor model. However, binary diagnostic analysis revealed that over half of the individuals meeting criteria for DPD also met criteria for dysthymia and that the best-fitting model allowed the psychological symptoms of dysthymia to load on both DPD and dysthymia latent factors. All of the individuals with DPD alone failed to meet criteria for dysthymia because they did not report chronic depressed mood. Our results suggest that although DPD is not synonymous with Dysthymia, it may be a milder subtype.     

The Two-Factor Solution to Allen and Meyer’s (1990) Affective Commitment Scale: Effects of Negatively Worded Items

Purpose

Affective organizational commitment is a construct important to both practitioners and researchers; thus, construct-valid measurement is needed. Allen and Meyer’s (J Occup Psychol 63:1–18, 1990) Affective Commitment Scale is a popular measure of affective organizational commitment. Although conceptualized as unidimensional, a two-factor solution sometimes emerges. Whether the two factors are substantive, reflecting AC-love and AC-joy constructs, or methodological, reflecting positively and negatively worded items, is unclear. This issue is examined in five studies.

Design/Methodology/Approach

In a new approach, conditions designed to produce cognitive fatigue are manipulated. Support for the method factor interpretation would be provided if the two-factor solution emerges only when participants are fatigued and negatively worded items are present. Cross-sample analyses are also conducted.

Findings

Analyses indicated that the two-factor solution fit the data well only when (a) participants were cognitively fatigued and (b) negatively worded items were present. This finding extended to both students and employees, and it held regardless of which items were negatively worded or whether negatively worded items were emphasized.

Implications

Results suggest that the second factor is likely methodological and seems to result from careless responding or fatigue on negatively worded items. It is suggested that users modify the items to be positively worded or administer the scale when respondents have sufficient cognitive resources to respond.

Originality/Value

This study was the first to use experimental methodology to test whether the two-factor solution is methodological or substantive. Results provide guidance for improving the scale’s construct validity in research and in practical applications.     

Confirmatory Factor Analysis of the Structure of Adult ADHD Symptoms

Previous research has examined the factor structure of ADHD symptoms in adults using confirmatory factor analysis and there is mixed support for two-factor, three-factor, or more complex bifactor models. The current study re-examines these factor structures on the basis of not only overall model fit, but also criteria such as chi-square difference tests, invariance, reliability, and validity. Three datasets were pooled to form a total sample of 430 adults (50% female). Participants completed questionnaires assessing their ADHD symptoms, education, psychopathology, and parenting (the latter as validity variables). Although the bifactor models demonstrated the best fit, the reliability and construct replicability of specific factors in these models was poor. The three-factor model had good fit and demonstrated good reliability, validity, construct replicability, and some invariance across gender and dataset. Our results replicate previous studies that find superior fit for bifactor models. However, the superior statistical fit may reflect only the increased complexity of these models. The more parsimonious three-factor model may demonstrate stronger validity and clinical utility.     

La satisfaction au travail des adultes handicapés mentaux : Adaptation du Questionnaire de Satisfaction du Minnesota

The purpose of the study was to present an adaptation of the Minnesota Satisfaction questionnaire (MSQ) for workers with mental disorders. Based on a sample of 181 respondents, the alpha coefficients indicated high reliability for all scores. The average scores of satisfaction are high for these workers. The original and theoretical two-factor model demonstrated inadequate model fit. A four-factor 17-item model provided an acceptable fit to the data. The results are discussed in the light of previous studies; suggestions for professional use and for future research are proposed.     

Factor structure of the Penn State Worry Questionnaire: examination of a method factor

The Penn State Worry Questionnaire (PSWQ) was originally designed as a unifactorial measure of pathological trait worry. However, recent studies supported a two-factor solution with positively worded items loading on the first factor and reverse-scored items loading on a second factor. The current study compared this two-factor model to a negative wording method factor solution among college students. A method factor model with all PSWQ items loading on a single worry factor and reverse-scored items loading on a negative wording method factor provided as good a fit as the two-factor model. This method factor alone did not predict a generalized anxiety disorder diagnosis. Finally, the psychometric properties of an abbreviated scale containing only positively worded items were examined. The PSWQ appears to measure a single unitary construct, but response patterns differ between positively worded and reverse-scored items. Theoretical implications for pathological worry and assessment-related issues are discussed.     

Additional factorial evidence of construct validity for the Visual Similes Test II with scores from a sample of African-American children

The Visual Similes Test II was designed to measure the construct of arousal. This study investigated its factor structure with scores from a sample of 154 African-American elementary school children (7 to 10 years). The initial factor structure was examined using principal axis factor analysis with the promax rotation. Confirmatory factor analysis was then used to evaluate the model-fit of the data with the hypothesized hierarchical model. Results provided support for the two-factor structure in the principal axis factor analysis and the model-fit of the hypothesized model in the confirmatory factor analysis.     

Testing Factorial Structure and Validity of the PCL:SV in Lithuanian Prison Population

This study examined the factorial structure and validity of the Hare Psychopathy Checklist: Screening Version (PCL:SV) in a European forensic context. A random sample of 257 criminal offenders from the Lithuanian prison population were administered the PCL:SV (Hart et al. 1995). The pattern of validity coefficients in this sample was comparable to other North American and non-North American samples. Several theoretical factorial structures for the PCL:SV were tested and compared. The two-factor model was not supported, while three- and four-factor models provided an acceptable fit to Lithuanian data. The four-factor model showed significantly better fit compared to the two-factor model. Correlations between PCL:SV factors and demographic variables confirm construct validity. However in the four-factor model, when controlling for correlations of the remaining three factors, only the Antisocial factor significantly correlated with variables related to criminal activity. It was concluded that the overall results of the PCL:SV in a male sample of Lithuanian offenders support cross-cultural generalizability of the construct of psychopathy as measured by the PCL:SV.     

Cognitive-affective stress propensity: A confirmatory factor analysis of stress propensity measures

A cognitive-affective stress propensity (CASP) construct is used to integrate previous findings regarding individual differences in experienced stress and resultant strain. A confirmatory factor analysis determined the structure of the CASP construct using a one factor model. This model and alternative models of factor structure contain two additional new constructs, psychological magnification and cognitive-affective connectivity. These two variables, and five trait variables previously identified as moderators in stress propensity research, were used in the analysis. Results show the one factor model to fit the data better than alternative models, thus supporting the notion of a latent construct (CASP).     

An investigation into the psychometric properties of the Hospital Anxiety and Depression Scale in individuals with chronic fatigue syndrome

The study sought to determine the psychometric properties of the Hospital Anxiety and Depression Scale (HADS) in individuals with chronic fatigue syndrome (CFS) assessed using a web-based data collection tool. Exploratory and confirmatory factor analyses were conducted on the HADS to determine its psychometric properties in 117 individuals with CFS. Seven models were tested to determine model fit to the data. Internal reliability estimations of the anxiety and depression sub-scales were found to be acceptable, however, a three-factor model was found to provide a significantly better fit to the data when compared to the bi-dimensional two-factor structure previously assumed to underpin the HADS' construct validity. The clinical utility of the HADS in the assessment of anxiety and depression in CFS appears to be fundamentally compromised by the presence of a three-dimensional underlying factor structure. Future revision of the HADS is recommended if the instrument is to be used reliably to screen CFS patients.     

The factor structure of ADHD items in DSM-III-R: Internal consistency and external validation

Previous research employing factor-analytic procedures to study the underlying dimensions of DSM-III attention deficit disorder with hyperactivity (ADDH) symptoms have consistently supported a two-factor model. Revision of the structure of the ADHD diagnosis in DSM-HI-R, as well as inclusion of new items, has raised the question of comparability of the two diagnoses. To explore the significance of these changes, teacher ratings of DSM-III ADDH items and DSM-III-R ADHD items of 85 nonreferred school children were factor-analyzed to determine their underlying factor structures. A similar two-factor solution was obtained for each diagnostic scale. The factors consisted of items believed to reflect inattention and hyperactivity-impulsivity constructs. These factors were further evaluated against results of a cognitive test battery to ascertain whether objective, external validation could be demonstrated. The hyperactivity-impulsivity factor scores were related to continuous performance test measures of response inhibition, while inattention-disorganization factor scores were related to measures of attention and visual search. Implications for assessment and diagnosis of ADHD are discussed.The authors gratefully acknowledge the assistance of Sister Hildegarde Koger, the St. Francis de Sales School, and the parents and children who participated in this study.     

The structure of disgust: domain specificity in relation to contamination ideation and excessive washing

The primary goal of the present study was to employ confirmatory factor analysis to compare two theoretical models regarding the factor structure of disgust (N=307). The two-factor model of Animal Reminder and Core disgust proposed by Rozin et al. (2000) demonstrated superior model fit over a one-factor model that has been implicated in prior research. However, contrary to theoretical predictions, categorizing Hygiene disgust as Core disgust rather than Animal Reminder disgust provided an overall better fit for the two-factor model. The second aim of the study was to investigate the relationship between the empirically derived two-factor model and contamination ideation and excessive washing using structural equation modeling. Findings indicated that the Contamination Ideation and Excessive Washing latent factor was specifically related to Core disgust (domain specific) and negatively related to Animal Reminder disgust. The relevance of these findings in the context of future research investigating the role of disgust in specific anxiety disorders is discussed.     

The joint WAIS-III and WMS-III factor structure: development and cross-validation of a six-factor model of cognitive functioning

During the standardization of the Wechsler Adult Intelligence Scale (3rd ed.; WAIS-III) and the Wechsler Memory Scale (3rd ed.; WMS-III) the participants in the normative study completed both scales. This "co-norming" methodology set the stage for full integration of the 2 tests and the development of an expanded structure of cognitive functioning. Until now, however, the WAIS-III and WMS-III had not been examined together in a factor analytic study. This article presents a series of confirmatory factor analyses to determine the joint WAIS-III and WMS-III factor structure. Using a structural equation modeling approach, a 6-factor model that included verbal, perceptual, processing speed, working memory, auditory memory, and visual memory constructs provided the best model fit to the data. Allowing select subtests to load simultaneously on 2 factors improved model fit and indicated that some subtests are multifaceted. The results were then replicated in a large cross-validation sample (N = 858).

Goal Orientation in Organizational Research: A Conceptual and Empirical Foundation

Although some have argued that goal orientation could be beneficially integrated into organizational research, progress in this area has been impeded by several problematic conceptual issues and a lack of validated dispositional measures. This research was intended to address these issues and to provide a foundation for future organizational research in this area. We argue that goal orientation is a two-dimensional construct that has both dispostional and situational components. In each of four independent studies, LISREL VIII confirmatory factor analyses (Jöreskog & Sörbom, 1993) illustrated that a two-factor model fit a set of goal orientation items better than a single-factor model. In addition, the latent goal orientations were found to be uncorrelated in each study. Moreover, correlational analyses indicated that demographic and substantive variables exhibited differential relationships with the latent learning goal and performance goal orientation constructs. Other analyses illustrated that the dispositional and situational aspects of goal orientation are distinguishable. Collectively, the results provided ample support for the convergent and discriminant validity of eight-item measures of each goal orientation and help to define the nomological network within which the two goal orientations reside. The importance of goal orientation as a multidimensional construct is discussed and several recommendations for further research are suggested.     

Assessing workplace bullying: Spanish validation of a reduced version of the Negative Acts Questionnaire

The aim of the present study was to validate a reduced Spanish version of the Negative Acts Questionnaire (NAQ; Einarsen & Raknes, 1997). This instrument, which has been widely used in various studies, was developed to measure workplace bullying. Two samples, the first comprising 352 employees from 11 organizations, and the second comprising victims of bullying who were recruited from 15 Spanish associations against bullying, participated in the study. Exploratory factor analysis conducted with the data from the first sample revealed a two-factor solution that accounted for 63.3% of the total variance. The data from the second sample were used for confirmatory factor analyses to compare three structure models of the NAQ (one factor, two independent factors, and two correlated factors). The results indicate that the correlated two-factor model provided the best fit to the data (chi2/df = 2.1, CFI = .93, GFI = .95, RMR = .04, RMSEA = .06, AIC = 215.4). Reliability analysis showed that this 14-item Spanish version had high internal consistency. Significant correlations between the NAQ and its dimensions and diverse health and perceived stress scales were found, which provided evidence of construct validity. Taken conjointly, the results of this study support the use of the Spanish version of the reduced NAQ in future research.     

A Revisit of General Self-Efficacy Scale: Uni- or Multi-dimensional?

While a large body of research provides strong evidence that general self-efficacy (GSE) is a unidimensional construct, no study has been conducted to test or compare its single-factor structure with alternative factor structures (e.g., two-factor structure). The main purpose of this study was to re-examine its factor structure in a Chinese context. The Chinese version of GSE scale was administered to 195 Chinese university students. Personal identity and optimism instruments were also used to examine the predictive validity of GSE. Exploratory factor analysis determined that a two-factor solution was best fitting, explaining 54.49 % of the variance, which was reproduced reliably in the two subsamples. Through a series of factor model testing by confirmatory factor analysis, findings indicated that the two-factor structure was reliable, internally valid as demonstrated. Subsequent regression analyses also showed that only one of the two factors significantly predicted personal identity and optimism, whereas the other one was irrelevant. The findings emphasized the value of revisiting GSE as a uni- or multi-dimensional construct.     

Executive Function Among Preschool Children: Unitary Versus Distinct Abilities

Working memory (WM) and inhibitory control (IC) are considered related but separable executive functions (EFs) among adults and adolescents. Although available evidence suggests that these constructs have not diverged, especially among younger preschool children, questions remain regarding the age at which separable factors emerge.This study used confirmatory factor analysis to test a 2-factor model of EF among 289 preschool children whose ages ranged from 45 to 63 months (M?=?55.74, SD?=?7.56). As hypothesized, the model including separate but related factors provided a significantly better fit than a unitary model, indicating the presence of distinct WM and IC factors. Based on evidence that WM and IC measured during preschool relate differently to a variety of academic and behavioral outcomes, it was hypothesized that a model including separate factors for each EF would fit the observed data better than a single-factor model. Although the two-factor model provided the best fit for the full sample, the correlation between WM and IC factors was significantly higher for younger (??=?.95) than older (??=?.68) children, indicating increasing divergence as a function of age.
