Abstract The objective of this study is to investigate the evidence of construct validity of a phonological awareness instrument. Exploratory factor analysis was carried out on data collected from 510 elementary and middle school students in 2nd and 6th grades attending two different public schools in the city of São Paulo, Brazil; most were males with mean age of 8.4 years. Confirmatory factor analysis was carried out on data collected from 427 students from other four Brazilian states in the same grades; most were females with mean age of 9.3 years. The instrument used was the Roteiro de Avaliação da Consciência Fonológica, a phonological awareness test. The exploratory factor analysis showed a three-factor solution. As for the confirmatory factor analysis, of the two models tested, the one that indicated better model fit indices was composed of three factors. The model found is adequate for the task carried out in this study. However, more studies should be carried out to further refine the instrument.

Positive attitudes towards breastfeeding in health professionals/students have been associated with increasing their confidence to provide support and accompaniment to mothers. In Mexico, there is no valid/reliable tool to assess attitudes towards breastfeeding in this population. The Australian Breastfeeding Attitudes (and Knowledge) Questionnaire (ABAQ) measures attitudes in the Australian population. We aimed to adapt and validate the ABAQ in Mexican health students. We included 264 health students (nursing, nutrition, and medicine) from the University of Guadalajara. Bilingual translators carried out the Spanish adaptation with a reverse translation into English. Experts evaluated the content validity. Reliability was evaluated through an internal consistency analysis (Cronbach’s alpha) and construct validity through convergent–divergent validation, item–total correlation, exploratory factor analysis (by principal components), and confirmatory factor analysis. According to the exploratory factor analysis, only one component was identified. Seven items were removed (low correlation between items ≤0.2 and low factor load ≤0.3). The Cronbach’s alpha was 0.78. According to the confirmatory factor analysis, the one-factor solution of the ABAQ-13Mx showed a good model fit (X2 = 98.41, G = 62, p = 0.02, CFI = 0.940, and RMSEA = 0.048). The ABAQ-13Mx is a reliable and valid instrument for evaluating attitudes towards breastfeeding in Mexican health degree students.

<p style="text-align: justify;">This study was conducted to corroborate in understanding the teachers’ beliefs about assessment practices. The prior studies related to teachers’ assessment beliefs in mathematics have been done to assess teachers’ beliefs in the general context of mathematics teaching. This study developed an instrument to assess teachers’ assessment beliefs of mathematical thinking. The research aimed to develop and validate a scale of assessment beliefs of mathematical thinking by using the confirmatory factor analysis. The first draft of the scale contained 25 items. The sample of the study consisted of 537 mathematics teachers from public schools in Oman. The instrument was a questionnaire with a 5-point Likert scale. The scale was validated by asking a number of experts in mathematics educational measurement and evaluation. Exploratory and confirmatory factor analysis was applied to test the model of assessment beliefs of mathematical thinking scale using AMOS 25.0. All constructs had acceptable reliability. The model had a good model fit for the assessment beliefs of mathematical thinking scale which obtainable from the fit indices tests. The findings revealed that all fit criteria indices were realized. The results also showed acceptable validity and construct reliability for the scale.</p>

This study examined the construct validity of the Graduate Academic Potential Test (PAPS). The examination was performed on all existing PAPS series (6 forms) to identify the consistency of dimensionality structure of PAPS. Data of this study were analyzed using confirmatory factor analysis (CFA). The results of the analysis support assumption that the structure of the PAPS test is unidimensional. All of the model fit indices support the decision that the unidimensional model fit the data. The study also examined factor loading that the non-verbal components, especially the quantitative components that had a higher factor weight than the other components.

This study examined the psychometric properties of the Evidence-Based Practice Questionnaire (EBPQ). The 24-item EBPQ was developed to measure health professionals’ attitudes toward, knowledge of, and use of evidence-based practice (EBP). A confirmatory factor analysis was performed on the EBPQ given to a random sample of National Association of Social Work members (N = 167). The coefficient alpha of the EBPQ was .93. The study supported a 23-item 3-factor model with acceptable model fit indices (χ² = 469.04; RMSEA = .081; SRMR = .068; CFI = .900). This study suggests a slightly modified EBPQ may be a useful tool to assess social workers’ attitudes toward, knowledge of, and use of EBP.

To gain more insight in family processes, psychometrically tests are required. The present study aimed to adapt a reduced version of the Young Parenting Inventory (YPI) to the Portuguese language and to obtain evidence of its validity. The instrument was administered to a sample of 920 persons (59% female) with an average age of 21.3 years. Exploratory factor analysis indicated the existence of five factors explaining approximately 45% of the variance. Confirmatory factor analysis showed fit indices above.80. In comparison with other models, the five factor model showed a better fit to the data. Between the YPI and Familiograma (another test of family processes) moderate correlations were observed. The results of this study suggest satisfactory evidence of the validity for the YPI in Brazil.

Abstract Implicit theories (also referred to self-theories) represent a cognitive conceptualization about a matter, generally raised as a belief. It is marked as the primary aspect of cognitive processing among living beings affecting their overall behavior towards others’. In the present study, it is attempted to consider a Pakistani perspective on this phenomenon of self-theories and also to validate the implicit theories Scale. It is a measure of people’s beliefs about things to be fixed or changeable. A quantitative approach of correlational methodology was employed. Participants of the study were 355 Pakistani young adults with an age range of 20–30 years (M = 23.08, SD = 1.99). There were 175 males and 180 females (as they reported their gender) from Islamabad. Confirmatory factor analysis was computed to assess the dimensionality of the scale. An adequate model fit indices were found as Root Mean Square Error of Approximation = .04, Comparative Fit Index = .99, Tucker-Lewis Index = .98, Goodness of Fit Index = .97, and Incremental Fit Index = .99, confirming a bidimensional implicit theories measure. The reliability coefficients of Entity Theory and Incremental Theory subscales were assessed through internal consistency and test-retest methods which are found to be in an acceptable range. Demographic specifications are also addressed to reflect upon the indigenous importance of this concept. This will be an additive feature in the literature to consider the cultural specification enabling individuals to align their mindsets in the desired direction of growth and achievement.

This study focused on the statistical technique using factor analysis to validate the scale measuring high school students’ attitudes towards Biology. The study sample consisted of 500 students (male = 220, female = 280) from public and private institutions offering high school education with Biology as an elective subject, in Islamabad. As part of this study, the scale developed by (Ahmad and Jamil, 2019) for the attitude of students towards biology was adopted. Research has shown that attitude and achievement are interrelated. Previously, research studies used exploratory factor analysis to analyze the validity of the scale construction. The present study used exploratory and confirmatory factor analysis to fill the gap in the literature because, after exploratory factor analysis, confirmatory factor analysis is required to test whether the models estimate the intended theoretical constructs. Following the procedure of factor analysis, six factors of the Biology Attitude Scale (BAS) were identified. The findings of the study show that the scale had a multidimensional construct. Further, the internal consistency reliability analysis was performed. Cronbach’s alpha coefficient was 0.86 which shows high internal consistency. It is recommended that BAS is a reliable and valid measurement tool that can be used to determine the attitude of secondary students towards Biology.

Abstract. Physical exercise when done excessively may have negative consequences on physical and psychological wellbeing. There exist many scales to measure this phenomenon. The purpose of this article is to create a scale measuring the problematic practice of physical exercise (PPPE Scale) by combining two assessment tools already existing in the field of exercise dependency but anchored in different approaches (EDS-R and EDQ). This research consists of three studies carried out on three independent sample populations. The first study (N = 341) tested the construct validity (exploratory factor analysis); the second study (N = 195) tested the structural validity (confirmatory factor analysis) and the third study (N = 104) tested the convergent validity (correlations) of the preliminary version of the PPPE scale. Exploratory factor analysis identified six distinct dimensions associated with exercise dependency. Furthermore, confirmatory factor analysis validated a second order model consisting of 25 items with six dimensions and four sub-dimensions. The convergent validity of this scale with other constructs (GLTEQ, EAT26, and The Big Five Inventory [BFI]) is satisfactory. The preliminary version of the PPPE must be administered to a large population to refine its psychometric properties and develop scoring norms.

The Worry Domains Questionnaire was proposed as a measure of both pathological and nonpathological worry, and assesses the frequency of worrying about five different domains: relationships, lack of confidence, aimless future, work, and financial. The present study analyzed the factor structure of the long and short forms of the WDQ (WDQ and WDQ-SF, respectively) through confirmatory factor analysis in a sample of 262 students (M age = 21.8; SD = 2.6; 86.3% females). While the goodness-of-fit indices did not provide support for the WDQ, good fit indices were found for the WDQ-SF. Furthermore, no source of misspecification was identified, thus, supporting the factorial validity of the WDQ-SF scale. Significant positive correlations between the WDQ-SF and its subscales with worry (PSWQ), anxiety (STAI-T), and depression (BDI) were found. The internal consistency was good for the total scale and for the subscales. This work provides support for the use of the WDQ-SF, and potential uses for research and clinical purposes are discussed.

This study investigates the equivalent factorial structure of the Brief Symptom Inventory (BSI) in clinical and nonclinical Jordanian populations, using both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The 53-item checklist was administered to 647 nonclinical participants and 315 clinical participants. Eight factors emerged from the exploratory factor analysis (EFA) for the nonclinical sample, and six factors emerged for the clinical sample. When tested by parallel analysis (PA) and confirmatory factor analysis (CFA), the results reflected a unidimensional factorial structure in both samples. Furthermore, multigroup CFA showed invariance between clinical and nonclinical unidimensional models, which lends further support to the evidence of the unidimensionality of the BSI. The study suggests that the BSI is a potentially useful measure of general psychological distress in clinical and nonclinical population. Ideas for further research are recommended.
