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.     

Cross-ethnic equivalence of the Hopkins Symptom Checklist-21 in European American, African American, and Latino college students

To determine if the Hopkins Symptom Checklist-21 demonstrates equivalent validity across different ethnic groups, the authors tested the factor structure of the instrument with a sample of European American (n = 514), African American (n = 154), and Latino (n = 229) college students using confirmatory factor analysis with tests of invariance across groups. For the most part, a 3-factor model with Performance, General, and Somatic factors fit equally well for all 3 racial/ethnic groups. Differences involved only a few items in terms of either the strength of a factor loading or an error term. The results generally support the validity of the use of the instrument for measurement of distress in these different racial/ethnic groups.     

The Maslach Burnout Inventory: Factorial validity and consistency across occupational groups in Norway

The present study tested the factorial validity of the Maslach Burnout Inventory among 1590 human service workers. Confirmatory factor analyses of the total sample as well as multi‐group analyses and analyses of each of seven professional groups separately, indicated that the original three‐factor model of the MBI provided a reasonable fit to the data. However, a factorial model with items 12 and 16 removed provided a superior fit, with two of the fit indices over .90 and an RMSEA value of .06. The results of a multi‐group analyses for the seven occupational groups showed a slightly poorer fit to the data than in the total sample. With a few exceptions, the fit indices of the models tested for each subsample separately indicated similar results, and the proposed 20‐item model also provided the best fit for the subsamples. Internal consistencies of the subscales of the MBI were acceptable, and test‐retest reliability indicated stability of scores over a 6‐month interval. These results indicated that the proposed three‐factor structure of the MBI based on 20 items can be replicated in the total sample as well as across occupations within human services in Norway.     

Assessing the factorial invariance of Harter's self-concept measures: comparing preadolescents with and without spina bifida using child,parent, and teacher report

The purpose of this study was to determine whether the structure of children's self-concept, as rated by children themselves on the Self-Perception Profile for Children (SPPC; Harter, 1985), and the structure of children's competence, as rated by their parents on the Rating Scale of Child's Actual Behavior (PRS) and teachers on the Rating Scale of Child's Actual Behavior (TRS; Harter, 1985), are similar across samples of children with and without spina bifida (children were 8 and 9 years of age; n = 68 in each sample). Using confirmatory factor analyses, results revealed that a multidimensional model for the SPPC and the TRS fit the data well for both samples. On the other hand, the model for both mothers' and fathers' PRS ratings did not fit the data for the spina bifida sample. Further tests of factorial invariance conducted on the SPPC and TRS revealed that the spina bifida and able-bodied samples tended to have the same pattern and magnitude of factor loadings for both instruments. There was some invariance, however, in the amount of unique error variance accounted for across samples. These results bolster our confidence in using the SPPC and TRS to compare children with and without spina bifida.     

A confirmatory analysis of the factor structure and cross-age invariance of the Wechsler Adult Intelligence Scale-Third Edition

In the Wechsler Adult Intelligence Scale-Third Edition (WAIS-III; D. Wechsler, 1997), the manual reports several confirmatory factor analyses in support of the instrument's latent factor structure. In practice, examiners frequently compare an examinee's score from a current administration of the WAIS-III with the results from a previous test administration. Implicit in test-retest score comparisons is evidence that scores retain similar interpretive meaning across time. Establishing an instrument's factorial invariance provides the foundation for this practice. This study investigated the factorial invariance of the WAIS-III across the instrument's 13 age groups. The overall results from this study generally support both configural and factorial invariance of the WAIS-III when the 11 primary tests are administered.

Factorial Structure and Measurement Invariance of the Innovative Behavior Questionnaire

The article presents an analysis of the factorial structure and measurement invariance of the Innovative Behavior Questionnaire, developed by Scott and Bruce. Although the instrument is widely used to capture individuals' innovative behavior, very little evidence concerning its psychometric properties is available. A time‐lagged study among 382 employees was conducted to check the factorial structure of the questionnaire, using confirmatory factor analysis, as well as its measurement invariance across gender and time. One‐factor structure (with correlated error terms of first three items) and strict invariance across time and across gender of the Innovative Behavior Questionnaire were demonstrated. As such, the measure can be used as a reliable tool for capturing individuals' innovative behavior by self‐report.     

Exploring the structure of Zuckerman's Sensation Seeking Scale, Form V in a Spanish sample

The psychometric properties of the original version of the Sensation Seeking Scale (Form V) were analyzed in a sample of 1,006 Spanish university students. The total sample was randomly split into two halves. Exploratory factor analyses were conducted on the calibration sample (n=504), whereas confirmatory factor analysis procedures were performed on the validation sample (n=502). As previous studies have suggested, exploratory factor structure indicated that several items load on a different factor or have loadings lower than .30. Those problems were surpassed when the best five items per factor were factor analyzed again. The confirmatory factor analyses showed that a 4-factor simple structure model gave a clearly imperfect fit. A model of 20 items (5 items per factor) gave a better fit, although with similar problems regarding the low reliabilities of the Experience Seeking and Boredom Susceptibility subscales. The need for improvement of the four-factor structure is discussed.     

Factorial structure and invariance across gender of the Swedish self-consciousness scale

In this study, I tested different factor models and the factorial invariance across gender for the Self-Consciousness Scale (Fenigstein, Scheier, & Buss (1975) using confirmatory factor analyses. University students (251 women and 259 men) completed the Swedish version of the scale. A respecified (Item 15 loading on the factor Internal State Awareness [ISA] instead of on the factor Self-Reflection [SR]) 17-item, 4-factor model of Burnkrant and Page (1984) including the factors SR, ISA, Public Self-Consciousness, and Social Anxiety demonstrated the best fit for both men and women. Factor intercorrelations were overall stronger for women. The respecified model demonstrated factorial invariance across gender. I discuss the strengthening of scale reliability through the expansion of subscale items and invariance testing across groups.     

Multigroup Confirmatory Factor Analysis of the Cognitive Dysfunction Questionnaire: Instrument refinement and measurement invariance across age and sex

Vestergren, P., Rönnlund, M., Nyberg, L. & Nilsson, L.‐G. (2012). Multigroup confirmatory factor analysis of the Cognitive Dysfunction Questionnaire: Instrument refinement and measurement invariance across age and sex. Scandinavian Journal of Psychology 53, 390–400. The study adopted Confirmatory Factor Analysis (CFA) to investigate the factorial structure and reduce the number of items of the Cognitive Dysfunction Questionnaire (CDQ). The analyses were based on data for a total of 1,115 participants from population based samples (mean age: 63.0 ± 14.5 years, range: 25–95) randomly split into a refinement (N = 569) and a cross‐validation (N = 546) sample. Equivalence of the measurement and structural portions of the refined model was demonstrated across the refinement and cross‐validation samples. Among competing models the best fitting and parsimonious model had a hierarchical factor structure with five first‐order and one second‐order general factor. For the final version of the CDQ, 20 items within five domains were selected (Procedural actions, Semantic word knowledge, Face recognition, Temporal orientation, and Spatial navigation). Internal consistency reliabilities were adequate for the total scale and for the subscales. Multigroup CFAs indicated measurement invariance across age and sex up to the scalar level. Finally, higher levels of cognitive dysfunction as reflected by CDQ scores were predicted by advancing age, fewer years of education, and with deficits in general cognitive functioning as reflected by scores on the Mini‐Mental State Examination. In conclusion, the CDQ appears to be psychometrically sound and shows the expected relationships with variables known to be associated with cognitive dysfunction and dementia. Future studies should apply it among clinical groups to further test its usefulness.     

Measurement of Creative Teaching in Mathematics Class

The current study serves two main purposes: (1) proposing a framework suggesting several conditions that mathematics teachers should establish to increase student creativity, and (2) developing and validating a scale based on the framework, aimed at measuring to what extent mathematics teachers establish a learning environment for their students to foster creativity. The analysis benefited from Sternberg’s Investment Theory of Creativity and Cropley’s framework in addition to other studies on creativity when developing the scale. The participants consisted of two groups of mathematics teachers. Data from the first group (n = 423) were used for exploratory factor analysis. The second group (n = 410) were used for confirmatory factor analysis. Based on results of the exploratory factor analysis, 5 items were removed from the scale. Results of confirmatory factor analysis supported the construct validity of the trimmed scale. Based on these results, there is evidence that the scale can be employed confidently to measure different dimensions of creativity-fostering behaviors of mathematics teachers.     

Factor analysis of the Spanish Burnout Inventory among public administration employees

Burnout has been recognized as an important stress‐related problem. Researchers have been troubled by some of the psychometric limitations of the questionnaires developed to evaluate burnout. This study was designed to assess the factor structure of the Spanish Burnout Inventory in a sample of 548 Brazilian public administration employees. This instrument comprises 20 items distributed in four dimensions: enthusiasm toward the job (5 items), psychological exhaustion (4 items), indolence (6 items), and guilt (5 items). The factor structure was examined through confirmatory factor analysis. To assess the factorial validity of the Spanish Burnout Inventory, four alternative models were tested. The four‐factor model obtained an adequate data fit for the sample, χ²(164) = 514.358, p < .001, RMSEA = .062, GFI = .910, NFI = .915, CFI = .940, and AIC = 606.358. The results showed that the four‐model factor of the Spanish Burnout Inventory possesses adequate psychometric properties in the Brazilian cultural context. Implications for future research and practice are also discussed.     

Psychometric Properties of the Multidimensional Perfectionism Scale of Hewitt in a Dutch-Speaking Sample: Associations With the Big Five Personality Traits

We administered the Dutch Multidimensional Perfectionism Scale of Hewitt and Flett (1991, 2004) in a large student sample (N = 959) and performed a confirmatory factor analysis to test the factorial structure proposed by the original authors. The existence of a method factor referring to the negatively keyed items in the questionnaire was investigated by including it in the tested models. Next, we investigated how the 3 perfectionism dimensions are associated with the Five-factor model (FFM) of personality. The 3-factor structure originally observed by the authors was confirmed, at least when a method factor that refers to the negatively keyed items was included in the model. Self-oriented and socially prescribed perfectionism were both distinguished by low extraversion and low emotional stability. Self-oriented perfectionism's positive relationship with both conscientiousness and openness to experience differentiated the 2 perfectionism dimensions from each other. Other-oriented perfectionism was not well-characterized by the Big Five personality traits.     

Reliability and factor structure of the Finnish version of the Sport Imagery Questionnaire

The aim of this study was to examine the reliability and factor structure of the Finnish version of the Sport Imagery Questionnaire, a measure which examines cognitive and motivational functions of imagery. The final sample comprised 231 participants drawn from 34 sports and ranging in age from 14 to 49 years (M = 20.9, SD = 5.8). Internal consistency and confirmatory factor analyses were undertaken to evaluate the reliability and factorial validity of the scale. Fit indices and modification data generated from examining the 30-item five-factor model were equivocal, suggesting minor amendment and recategorization of several items rather than major adjustment to the proposed latent factor structure. Cronbach coefficients alpha indicated the scale is reliable. Overall, these results provide positive additional support for the claim that the Sport Imagery Questionnaire has a reproducible factor structure and is a reliable test for measuring imagery use in Finnish athletes.     

Validation study of the Questionnaire on School Maladjustment Problems (QSMP)

The aim of this study was to analyze the exploratory and confirmatory structure, as well as other psychometric properties, of the Cuestionario de Problemas de Convivencia Escolar (CPCE; in Spanish, the Questionnaire on School Maladjustment Problems [QSMP]), using a sample of Spanish adolescents. The instrument was administered to 60 secondary education teachers (53.4% females and 46.6% males) between the ages of 28 and 54 years (M= 41.2, SD= 11.5), who evaluated a total of 857 adolescent students. The first-order exploratory factor analysis identified 7 factors, explaining a total variance of 62%. A second-order factor analysis yielded three dimensions that explain 84% of the variance. A confirmatory factor analysis was subsequently performed in order to reduce the number of factors obtained in the exploratory analysis as well as the number of items. Lastly, we present the results of reliability, internal consistency, and validity indices. These results and their implications for future research and for the practice of educational guidance and intervention are discussed in the conclusions.     

Examining the multidimensionality of approaches to learning through the development of a revised version of the Learning Process Questionnaire

Aim: This study aimed to produce a revised two‐factor version of the Learning Process Questionnaire (R‐LPQ‐2F) with deep and surface approach scales, measured by a reasonably small number of items, suitable for use by teachers in secondary schools to evaluate the learning approaches of their students. Method: A set of 41 items was derived, with modification, from the original version of the LPQ and from items used to develop the revised version of the SPQ. These items were tested using reliability procedures and confirmatory factor analysis and items were deleted until scales were of a suitable length and confirmatory factor analysis indicated a good fit to the intended two‐factor structure. Sample: The sample consisted of 841 students from 20 secondary schools in Hong Kong. Results: The final two‐factor version of the questionnaire had good Cronbach alpha values and reasonable goodness‐of‐fit values for the confirmatory analysis. There was a much better fit, though, to a hierarchical structure with motive and strategy subscales for each approach, each of which, in turn, had two subcomponents. Conclusion: Approaches to learning have a hierarchical dimensionality with motive and strategy elements. Each motive and strategy element is itself multidimensional. The results are used to question the conventional approach to the testing and acceptance of instruments, which place sole reliance upon reliability tests. The use of confirmatory factor analysis is recommended as a routine procedure in the development and testing of instruments.     

The Italian version of the Empathy Questionnaire for 18- to 36-months-old children: psychometric properties and measurement invariance across gender of the EmQue-I13

Empathy is the basic ability to respond affectively to the emotions of others and is observed early in human development. This study (N = 304) tested the Italian version of the Empathy Questionnaire (EmQue), which is a parent scale assessing empathy-related behaviors in toddlers. For this study, it was completed by participants’ mothers only. The EmQue measurement model and its factorial invariance across children’s gender were tested via confirmatory factor analysis. Highly satisfactory goodness-of-fit indexes were found for a three factor-structure (contagion, attention to the feelings of others and prosocial actions) with 13 loading items. Furthermore, the data supported invariance of measurement across gender groups. These results suggest that the EmQue-I13 is a reliable instrument for investigating empathy and prosocial behavior in 18- to 36-month-old children in the Italian context.     

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.
