Multigroup exploratory factor analysis (EFA) has gained popularity to address measurement invariance for two reasons. Firstly, repeatedly respecifying confirmatory factor analysis (CFA) models strongly capitalizes on chance and using EFA as a precursor works better. Secondly, the fixed zero loadings of CFA are often too restrictive. In multigroup EFA, factor loading invariance is rejected if the fit decreases significantly when fixing the loadings to be equal across groups. To locate the precise factor loading non-invariances by means of hypothesis testing, the factors’ rotational freedom needs to be resolved per group. In the literature, a solution exists for identifying optimal rotations for one group or invariant loadings across groups. Building on this, we present multigroup factor rotation (MGFR) for identifying loading non-invariances. Specifically, MGFR rotates group-specific loadings both to simple structure and between-group agreement, while disentangling loading differences from differences in the structural model (i.e., factor (co)variances).  相似文献

Childhood trauma is a major public health problem which has an impact on personality development, yet no studies have examined the association between exposure to trauma and personality in a sample of Chinese adolescents. Four hundred eighty-five students completed the Childhood Trauma Questionnaire-Short Form (CTQ-SF) and the Eysenck Personality Questionnaire (EPQ). The CTQ-SF cut-off scores for exposure were used to calculate the prevalence of trauma. The possible associations between specific types of trauma and the EPQ subscale scores were examined. The rates of emotional abuse (EA), physical abuse (PA), sexual abuse (SA), emotional neglect (EN), and physical neglect (PN) were 18.76%, 11.13%, 27.01%, 49.48%, and 68.66%, respectively. Individuals subjected to EA, PA, and SA had significantly higher neuroticism (EPQ-N) and psychoticism (EPQ-P) scores on the EPQ compared with those who had not experienced EA, PA, or SA (all p values < 0.05). Significant positive correlations existed between CTQ-SF subscale scores for EA, SA, CTQ-SF total scores, and EPQ-N, EPQ-P scores (all p values < 0.05). Significant number of subjects in this adolescent sample reported experience of childhood abuse and neglect. Exposure to childhood trauma is associated with personality development in Chinese adolescents.  相似文献

ObjectiveThe Childhood Trauma Questionnaire-Short Form (CTQ-SF) is a self-report questionnaire that retrospectively provides screening for a history of childhood abuse and neglect, and which is widely used throughout the world. The current study aimed to examine the psychometric properties of the Chinese version of the CTQ-SF.MethodsParticipants included 3431 undergraduates from Hunan provinces and 234 depressive patients from psychological clinics. Confirmatory factor analysis was performed to examine how well the original five-factor model fit the data and the measurement equivalence of CTQ-SF across gender. Internal consistency was also evaluated.ResultsThe five-factor model achieved satisfactory fit (Undergraduate sample TLI = 0.925, CFI = 0.936, RMSEA = 0.034, SRMR = 0.046; depressive sample TLI = 0.912, CFI = 0.923, RMSEA = 0.044, SRMR = 0.062). Measurement invariance of the five-factor model across gender was supported fully assuming different degrees of invariance. The CTQ-SF also showed acceptable internal consistency and good stability.ConclusionThe current study provides that the Chinese version of the Childhood Trauma questionnaire-short form has good reliability and validity among Chinese undergraduates and depressive samples, which also indicates that the CTQ-SF is a good tool for child trauma assessment.  相似文献

BackgroundThe Childhood Trauma Questionnaire – Short Form (CTQ-SF) is a widely utilized self-report instrument in the assessment and characterization of childhood trauma. Yet, research on the instrument’s psychometric properties in clinical samples is sparse, and the Danish version of the CTQ-SF has not been previously evaluated in clinical samples.ObjectivesTo examine the structural validity, internal consistency reliability, and multi-method convergent validity of the CTQ-SF in a heterogenous clinical sample from Denmark.Participants and settingThe study was based on data from four Danish clinical samples (N = 393): 1) Outpatients diagnosed with personality disorders, 2) Patients commencing psychiatric treatment for non-affective first-episode psychosis, 3) Patients diagnosed with first-episode or prolonged depression recruited from general practitioners and an outpatient mood disorder clinic, and 4) detained delinquent boys.MethodsConfirmatory factor analysis was used to explore structural validity. Also, we calculated internal consistency and multi-method convergent validity with interview-based ratings of adverse parenting.ResultsConfirmatory factor analyses indicated that the five-factor structure described in CTQ-SF manual with three error correlated items best fitted the data, as compared to various other models. Coefficients of congruence also supported factorial similarity across countries (i.e. US substance abuser and a mixed Brazilian sample). Internal consistency reliability was acceptable and comparable to estimates previously published. Multi-method convergent validity associations further corroborated the validity of the CTQ-SF.ConclusionThese findings provide support for the reliability and validity of the Danish version of the CTQ-SF in clinical samples.  相似文献

ABSTRACT

The school educational system in South Africa needs to improve the level of percentage pass rate in education. Therefore, the premise of the study reported on was to examine the key enabling factors that promote a high-performance school team in the operations of a co-educational secondary school in the South African context. The article further argues that by improving these school teams’ operations and team skills, the result would impact positively on increasing the pass rates in the classroom. Sampling from 30 schools in three regions of South Africa, spanning different socio-economic contexts, yielded data from 409 respondents of school staff members from all different operational levels, defined as the school operational teams (SOTs). Statistical analysis of data from the survey instrument utilised Structured Equation Modelling (SEM), Exploratory Factor Analysis (EFA) and Analysis of Variance (ANOVA). The model showed a positive and significant correlation of employee engagement with both the School High Performance Work Index (SHPWI) and Team Performance Index (TPI). The results showed that employee engagement was a key enabling factor in driving high performance of SOTs.  相似文献

This study is a methodological-substantive synergy, demonstrating the power and flexibility of exploratory structural equation modeling (ESEM) methods that integrate confirmatory and exploratory factor analyses (CFA and EFA), as applied to substantively important questions based on multidimentional students' evaluations of university teaching (SETs). For these data, there is a well established ESEM structure but typical CFA models do not fit the data and substantially inflate correlations among the nine SET factors (median rs = .34 for ESEM, .72 for CFA) in a way that undermines discriminant validity and usefulness as diagnostic feedback. A 13-model taxonomy of ESEM measurement invariance is proposed, showing complete invariance (factor loadings, factor correlations, item uniquenesses, item intercepts, latent means) over multiple groups based on the SETs collected in the first and second halves of a 13-year period. Fully latent ESEM growth models that unconfounded measurement error from communality showed almost no linear or quadratic effects over this 13-year period. Latent multiple indicators multiple causes models showed that relations with background variables (workload/difficulty, class size, prior subject interest, expected grades) were small in size and varied systematically for different ESEM SET factors, supporting their discriminant validity and a construct validity interpretation of the relations. A new approach to higher order ESEM was demonstrated, but was not fully appropriate for these data. Based on ESEM methodology, substantively important questions were addressed that could not be appropriately addressed with a traditional CFA approach.  相似文献

The purposes of this study were to (a) test the hypothesized factor structure of the Student-Teacher Relationship Scale (STRS; Pianta, 2001) for 308 African American (AA) and European American (EA) children using confirmatory factor analysis (CFA) and (b) examine the measurement invariance of the factor structure across AA and EA children. CFA of the hypothesized three-factor model with correlated latent factors did not yield an optimal model fit. Parameter estimates obtained from CFA identified items with low factor loadings and R2 values, suggesting that content revision is required for those items on the STRS. Deletion of two items from the scale yielded a good model fit, suggesting that the remaining 26 items reliably and validly measure the constructs for the whole sample. Tests for configural invariance, however, revealed that the underlying constructs may differ for AA and EA groups. Subsequent exploratory factor analyses (EFAs) for AA and EA children were carried out to investigate the comparability of the measurement model of the STRS across the groups. The results of EFAs provided evidence suggesting differential factor models of the STRS across AA and EA groups. This study provides implications for construct validity research and substantive research using the STRS given that the STRS is extensively used in intervention and research in early childhood education.  相似文献

ABSTRACT

Research about the structure of character has largely assessed purported universal attributes. However, character develops within specific social, cultural and institutional contexts. As part of the first wave of a longitudinal study (Project Arete) of character development among cadets at the United States Military Academy (USMA) at West Point, an institution with a core mission to develop leaders of character, we examined the factor structure of a set of 15 character attributes of specific relevance to the West Point context. Data were derived from self-report surveys (N = 1,549; 75.6% men) completed in spring 2017. Results of exploratory factor analysis (EFA) identified a 4-factor structure of character: Relational, Commitment, Honor and Machiavellian and a confirmatory factor analysis (CFA) provided evidence for the validity and measurement equivalence of the factors. We discuss implications for promoting and assessing character within the context of USMA and other institutions seeking to develop leaders of character.  相似文献

Adults with substance use disorders (SUDs) report a high prevalence of childhood abuse. Research in the general population suggests specific types of abuse lead to particular negative outcomes; it is not known whether this pattern holds for adults with SUDs. We hypothesized that specific types of abuse would be associated with particular behavioral and emotional outcomes among substance users. That is, childhood sexual abuse would be associated with risky sex behaviors, childhood physical abuse with aggression, and childhood emotional abuse with emotion dysregulation. 280 inpatients (M age = 43.3; 69.7% male; 88.4% African American) in substance use treatment completed the Childhood Trauma Questionnaire (CTQ), HIV Risk-Taking Behavior Scale, Addiction Severity Index, Difficulties with Emotion Regulation Scale (DERS), Distress Tolerance Scale (DTS), and Affect Intensity and Dimensions of Affiliation Motivation (AIM). Consistent with our hypotheses, the CTQ sexual abuse subscale uniquely predicted exchanging sex for cocaine and heroin, number of arrests for prostitution, engaging in unprotected sex with a casual partner during the prior year, and experiencing low sexual arousal when sober. The physical abuse subscale uniquely predicted number of arrests for assault and weapons offenses. The emotional abuse subscale uniquely predicted the DERS total score, AIM score, and DTS score. Among substance users, different types of abuse are uniquely associated with specific negative effects. Assessment of specific abuse types among substance users may be informative in treatment planning and relapse prevention.  相似文献

Abstract

South Africa re-entered the world economy after 1994 with several disadvantages, of which an exceptionally high unemployment rate and a low-skilled labour force were the most challenging. Each year over the past decade increasing numbers of jobs have been destroyed in South Africa. The challenge facing South Africa in addressing the problem of job creation is aggravated by the fact that its labour force is predominantly low skilled. Various innovative measures for enhancing the skills base in South Africa have been introduced since the first democratic elections in 1994. The new policies are designed to deal with the country's lack of international competitiveness and the low rates of investment in the development of human capital. Since 1994, several policies and strategies have been put in place with the aim of creating jobs in various sectors of the South African economy. This states that an integrated approach to the implementation of the different innovative policy frameworks by the responsible public service departments is needed. A model for prioritisation in skills formation is given.  相似文献

Chinese University of Hong Kong students (N = 844) selected a “good” and a “poor” teacher, and rated each using a Chinese translation of the Students' Evaluations of Educational Quality (SEEQ) instrument. Multigroup confirmatory factor analysis (CFA) models, based on a 3 × 2 design, were constructed to test the invariance of the SEEQ factor structure across 3 discipline groups (a between‐group comparison of ratings by students in arts, social sciences, and education; in business administration; and in engineering, medicine, and science) and across ratings of good and poor teachers (via within‐subjects comparison). The selected model imposed between‐group invariance constraints on factor loadings, factor correlations, and factor variances across the 3 discipline groups and within‐subjects invariance constraints on factor loadings across ratings of good and poor teachers. The results support the use of SEEQ in this Chinese setting, demonstrating the generality of North American research findings and the usefulness of CFA in this research area.  相似文献

The authors created a psychometrically sound instrument that could be used to examine K-12 teachers’ perceptions of arts integration. Ten content experts reviewed the initial survey items for construct-fit and readability. Scores from 354 K-12 teachers were examined for the survey’s initial factor structure through exploratory factor analysis (EFA). Then, scores from 1,072 K-12 teachers were analyzed to complete a confirmatory factor analysis (CFA) of the Putting the Arts and the Classroom Together (PACT) data. EFA results indicated a three-factor structure (i.e., value, willingness, and barriers), and CFA results produced model indices showing good fit of the three-factor model. For purposes of examining teachers’ practices in integrating the arts, establishing teacher receptiveness to arts integrated curriculum is important in designing and implementing any professional development program. This survey could be used to establish baseline participant perceptions for staging targeted professional development to support educators in creating appropriate arts integrated curricula.  相似文献

Abstract

In 2004, the South African Education and Labour Relations Council announced that an agreement had been reached to integrate several existing programmes on quality management in education into a new programme entitled Integrated Quality Management System (IQMS) for School-based educators. In order to help educators in a particular Province of South Africa to cope with the demands of this programme, an Advanced Certificate in Education was instituted. The first cohort of teacher-students taking this particular ACE was subsequently subjected to an empirical survey intended to determine the effectiveness of the training. It was found that although the ACE was deemed to be generally helpful for meeting the IQMS requirements, it also failed in several respects. The survey also exposed several aspects of outcomes-based education with which school educators seem to be constantly struggling. Certain changes will have to be made to the ACE itself, but also to the current South African outcomes-based curriculum approach.  相似文献

Abstract

Children with visible physical disabilities (CWPDs) living in rural areas of South Africa are a matter of particular concern. While all children living in rural areas face negative influences such as poverty and the high incidence of HIV/AIDS, this situation is exacerbated for CWPDs who are more vulnerable to these influences (Human Sciences Research Council). The aim of this research was to explore and describe the negative influences facing children with physical disabilities in rural South Africa utilising Bronfenbrenner's ecological model as a theoretical point of departure. A purposeful sampling strategy was used to select forty participants for a critical ethnographic study. Data were gathered through multiple strategies: interviews, observations, photos and drawings and analysed using a thematic approach. The findings indicated that children with physical disabilities experience negative influences in many domains of their everyday life: lack of resources, poverty, cultural beliefs and personal factors are a few of these domains that were identified. The complexity of the lack of resources for this marginalised group of children emerges from the interplay of these domains rather than a single domain.  相似文献

Researchers state that teachers in different contexts reported different technological pedagogical content knowledge (TPACK). This phenomenon may partially be explained by cultural differences. Based on this consideration, the development and validation of the Chinese pre-service teachers’ technological pedagogical content knowledge (CTPCK) scale is described in this article. The sample was split into two subsamples on random basis (n1 = 229, n2 = 207) for the purpose of conducting (1) exploratory factor analysis (EFA) and (2) confirmatory factor analysis (CFA), respectively. After the EFA, the CTPCK scale excluded six items and included eight factors with 42 items. Reliability and correlations were discussed. The findings revealed that the CTPCK scale was a valid and reliable instrument for measuring the TPACK of Chinese pre-service teachers’ knowledge with or without linking educational technology.  相似文献

OBJECTIVE: The goal of this study was to develop and validate a short form of the Childhood Trauma Questionnaire (the CTQ-SF) as a screening measure for maltreatment histories in both clinical and nonreferred groups. METHOD: Exploratory and confirmatory factor analyses of the 70 original CTQ items were used to create a 28-item version of the scale (25 clinical items and three validity items) and test the measurement invariance of the 25 clinical items across four samples: 378 adult substance abusing patients from New York City, 396 adolescent psychiatric inpatients, 625 substance abusing individuals from southwest Texas, and 579 individuals from a normative community sample (combined N=1978). RESULTS: Results showed that the CTQ-SF's items held essentially the same meaning across all four samples (i.e., measurement invariance). Moreover, the scale demonstrated good criterion-related validity in a subsample of adolescents on whom corroborative data were available. CONCLUSIONS: These findings support the viability of the CTQ-SF across diverse clinical and nonreferred populations.  相似文献

The purpose of this study was to develop a scale with which to examine students’ self-regulation (SR) in three types of online interaction. Using scale development steps, we constructed the online self-regulation questionnaire (OSRQ), a self-report survey. A total of 799 online students participated in the study. Data from 400 randomly selected participants were used for exploratory factor analysis (EFA), and data of the remaining 399 participants were used for confirmatory factor analysis (CFA). The EFA yielded three factors as hypothesized: SR in interaction between student and content, SR in interaction between student and student and SR in interaction between student and teacher. The CFA demonstrated that the factor structures appearing in the EFA were also observed with different participants. In addition, we found convergent validity in the OSRQ. The study contributes to understanding SR in online learning settings.  相似文献

In the present study, the second order structures of the 16PF-5 for 3, 4, 5 and 6 factors are analysed in a sample of 636 undergraduate students and their friends and relatives, with a mean age of 25.09 years (sd: 9.20). A two-stage analysis with Exploratory and Confirmatory Factor Analysis (EFA and CFA) was performed assigning subjects either to a calibration sample (314 subjects), or to a validation sample (322 subjects). First, EFAs were conducted for each of the 4-factor structures with the calibration sample, and second, CFAs were specified and assessed also for the 4-factor different structures. Four different situations were tested, simple structure, secondary loadings >.30, modification indices between covariance error terms >20, and modification indices between covariance error terms >15. Results show that the 16PF-5 simple structure yields poor fit indices throughout all models, although when incorporating secondary loadings and correlating the variances of the error terms with modification indices >15, the 5-factor model appears to be the best representation of observed data. The usefulness of CFA in the study of personality structural questionnaires is discussed in the light of these results.  相似文献

Abstract

This article explores the notion of an African(a) philosophy of education and its implications for university teaching in South Africa. African(a) philosophy of education brings into sharper focus the need to reconceptualise university teaching in South Africa, particularly along the lines of deliberative inquiry. This article examines constitutive meanings of African(a) philosophy of education and what it means for teachers both to be deliberative and to cultivate deliberation.  相似文献

A hierarchical and multi-dimensional model of self-concept is well-validated. Despite increasing evidence that self-concept comprises two latent factors related to perceptions of ‘competence’ and ‘affect’, many researchers continue to examine the impact of a unitary self-concept on educational outcomes. This study explores evidence for a 2-factor academic subject-specific self-concept factor structure and examines the association between these factors with self-efficacy in a sample of higher education students. Participants from two studies (N?=?314; N?=?475) were enrolled in introductory psychology courses. Exploratory (EFA) and confirmatory (CFA) factor analysis examined and confirmed the factor structure of two oblique self-concept factors, reflecting affect and competence, in both studies. Temporal invariance of the 2-factor model was supported. Despite a substantial literature that discriminates between self-concept and self-efficacy, self-efficacy appears to be itself a facet of competency self-concept.  相似文献
