AbstractReplicability has become a highly discussed topic in psychological research. The debates focus mainly on significance testing and confirmatory analyses, whereas exploratory analyses such as exploratory factor analysis are more or less ignored, although hardly any analysis has a comparable impact on entire research areas. Determining the correct number of factors for this analysis is probably the most crucial, yet ambiguous decision—especially since factor structures have often been not replicable. Hence, an approach based on bootstrapping the factor retention process is proposed to evaluate the robustness of factor retention criteria against sampling error and to predict whether a particular factor solution may be replicable. We used three samples of the “Big Five Structure Inventory” and four samples of the “10 Item Big Five Inventory” to illustrate the relationship between stable factor solutions across bootstrap samples and their replicability. In addition, we compared four factor retention criteria and an information criterion in terms of their stability on the one hand and their replicability on the other. Based on this study, we want to encourage researchers to make use of bootstrapping to assess the stability of the factor retention criteria they use and to compare these criteria with regard to this stability as a proxy for possible replicability.

Breastfeeding Attitudes

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.

This study aims to adapt the Sanctification of Marriage Questionnaire for Muslims inIndonesia. Adaptation of the Sanctification of Marriage Questionnaire is carried out throughthe stages: translation, providing evidence of construct validity and reliability. Evidence of construct validity was carried out by exploratory factor analysis followed by MGCFA (Multi-Group Confirmatory factor Analysis). In this study, we used a composite reliability. Subjects to reveal the factor structure of sanctification of marriage were 160 married individuals, while the subjects to test the stability of factor structure consisted of 102 husbands and 111 wives. The result of exploratory factor analysis shows that the construct of sanctification of marriage has three factors / dimensions, namely: belief, perceived sacred qualities and manifestation of God. The structure stability of sanctification of marriage was then empirically tested by MGCFA. The results of MGCFA showed that the three factors / dimensions of sanctification of marriage proved stable. The composite reliability coefficient of the Sanctification of Marriage Questionnaire was in a good category. Further research can be carried out to provide evidence of construct validity with predictive validity and concurrent validity of the Sanctification of Marriage Questionnaire. Limitations in this study are discussed further.Keywords: exploratory factor analysis, multi-group confirmatory factor analysis, muslim,sanctification of marriage, scale adaptation

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.

The aim of the research was to determine the number, characteristics, and the level of convergence of personality types extracted in the space of the three psycho-lexical conceptualizations of personality – The Big Five, HEXACO, and The Big Seven. The study was conducted on a sample consisting of 343 participants (55.7% female), aged 18–60 (M = 33.99). The participants completed the IPIP-50 (Big Five model operationalization), IPIP-HEXACO (HEXACO model operationalization) and the BF+2-70 (short version of the questionnaire for assessing seven lexical dimensions in Serbian language) questionnaires. Latent profile analysis was conducted in the space of dimension scores of the three questionnaires. The Bayesian information criterion suggested three-class solution to be optimal in the space of all three questionnaires. Analyzing the structure of latent profiles, the classes within the three models were interpreted as “resilient”, “reserved”, and “maladjusted”. The congruency of classes was analyzed by multiple correspondence analyses, which indicated a high convergence of types in the two-dimensional space. Results indicate a distinct similarity between the extracted profiles with the profiles from previous studies, generally pointing towards the stability of the three big personality prototypes.

Abstract The aim of this study was to construct and seek evidence for the validity of the Escala de Benevolência frente à Esquizofrenia (Benevolence Toward Schizophrenia Scale). Two studies were conducted in Joao Pessoa, Paraíba, Brazil. Study 1 describes the development and evidence of the factor validity of the Benevolence Toward Schizophrenia Scale with a sample composed of 200 university students aged 16 to 51 years old (M = 25.31; SD = 7.21). The data were subjected to exploratory factor analysis, which revealed one single seven-item factor that explained 37.74% of the variance and a satisfactory Cronbach’s alpha (0.77). The aim of Study 2 was to test the goodness-of-fit of the Benevolence Toward Schizophrenia Scale factor structure with a sample composed of 200 university students aged 16 to 52 years old (M = 24.82; SD = 6.97). The one-factor structure exhibited adequate goodness-of-fit; the composite reliability value was 0.83, which indicates scale stability and satisfactory psychometric parameters for assessing benevolent prejudice toward schizophrenia.

Abstract. This article examines the internal validity of the French version of the Big Five Questionnaire for Children (BFQ-C). We first performed confirmatory factor analyses (CFA) to determine the fit of the factor structure identified in previous research on the BFQ-C and then used exploratory factor analyses. A sample of 399 children (192 boys and 207 girls) recruited from elementary schools completed the BFQ-C in their classrooms. Participants were 8 to 12 years old with a mean age of 9.58 years (SD = 0.98). The results indicated poor goodness-of-fit statistics for the CFA solution. Exploratory factor analysis improved the model fit markedly over conventional CFA. The factor structure of the French version of the BFQ-C suggested reasonable fit for the five intercorrelated factors corresponding to the Big Five with the exploratory factor analyses, even if the fifth factor appeared to be more problematic than the other 4 factors.

Test Result

This study tries to explore the factors contributing to the source credibility of celebrities as brand endorsers and, subsequently, develops a conceptually integrated scale for the same in Indian perspective. To conduct an empirical investigation, a survey is conducted consisting of 432 participants. In this study, exploratory factor analysis (EFA) followed by confirmatory factor analysis (CFA) has been con-ducted. Exploratory factor analysis resulted in three factors or dimensions. All the indicators are strongly loaded into their respective construct. The Cronbach’s alpha, composite factor reliability and variance extracted measure for validity checks are found to be satisfactory. All pairs of inter-construct correlation are found to be positive and significant. The issue of multicollinearity did not bear a serious threat to the data. Common method effect of Harmen’s one-factor post hoc test result indicates that multidimensional three-factor model fits the data well than the one-factor model. These results are also invariant across different demographic profiles, namely, gender, educational qualification and age.

Exploratory Factor Analysis (EFA) is one of the most popular statistical models in psychological science. A key problem in EFA is to estimate the number of factors. In this paper, we present a new method for estimating the number of factors based on minimizing the out-of-sample prediction error of candidate factor models. We show in an extensive simulation study that our method slightly outperforms existing methods, including parallel analysis, the BIC, and Exploratory Graph Analysis. In addition, we show that among the high performance method our method is the one that is most robust across different specifications of the true factor model. We provide an implementation of our method in the R-package fspe.
