Abstract: Negative attitudes mean a barrier for People with Disability (PwD), but attitudes towards Deaf people are structurally different from the rest of the PwD. The aim of this study is to evaluate the factorial structure and internal reliability of the Attitudes towards Deafness Scale (ADS) applied in health professionals from Concepcion, Chile. The ADS was translated to Spanish and back-translated to English, then reviewed by public health experts, and a pilot application was carried out to 15 health professional to make final modifications. The Chilean ADS version was applied to 182 health professional from primary care centers and academics working in health schools. Reliability analysis with estimation of the Cronbach’s alpha coefficient, and exploratory factor analysis were made. The data presented adequate values to perform exploratory factor analysis (KMO=0.73; Bartlett’s sphericity test p <0.00001). A maximum likelihood extraction method and a Quartimax rotation method with Kaiser standardization were used for a four-factor model, in which 11 items presented loads of less than 0.5, so the final model was left with 11 items. A Cronbach’s alpha coefficient of 0.70 was determined in the final model, with an alpha of 0.77 for the first factor, 0.55 for the second, 0.77 for the third, and 0.61 for the fourth. The exploratory factor analysis suggested a four-dimensional structure for ADS Chilean version. The four subscales and the scale in general presented an adequate Cronbach’s alpha, suggesting acceptable internal consistency.

This study used exploratory factor analysis to test the factor structure of the Project for Educational Research That Scales (PERTS) instrument. Research that reports the reliability, construct validity, and factor structure of the PERTS scale is useful for interpreting the results from the use of the widely distributed survey and for suggesting interventions to develop an academic mindset in the classroom. Correlations and exploratory factor analyses were performed using pre-existing data from a medium-sized, rural school district, in a large southwestern state of the U.S. as self-reports from a sample of 2,908 students, in grades 3 through 8, at three elementary and two middle schools. Results of the exploratory factor analysis confirmed the proposed four-factor structure. The PERTS survey demonstrated internal reliability on three of the four scales above the pre-determined indices of Cronbach’s alpha > .80, with the exception of the individual mindset scale with a Cronbach’s alpha of .772.

Background: After introducing the emotional schema model, two questionnaires are proposed to assess this structure. This study is the first validation research on the Relationship Emotional Schema scale (RESS) worldwide. Objectives: The present study aimed to assess the factor structure and psychometric properties of RESS among Iranian victims of domestic violence. Materials and Methods: This study used a correlational method, and the research population encompassed couples with the experience of domestic violence, who had referred to the Forensics Center of Sari Province in 2018. The sample size of the study was determined to be 227 persons selected by the convenience sampling method. To implement RESS for Iranian population after back translation, a pilot study was conducted on 50 persons. Moreover, internal consistency and exploratory factor analysis were performed to check its structure validity. Results: Fourteen items have a significant correlation with the scores of the relevant subscale (negative and positive relationship emotional schema). The reliability of these two dimensions was acceptable, as confirmed by Cronbach’s alpha coefficient with a range of 0.68 to 0.74. The total value of Cronbach’s alpha coefficient was 0.71. Exploratory factor analysis revealed four factors of RESS. Furthermore, a two-factor structure was extracted, and the correlation between items confirmed the structure validity of the scale. Convergent validity analyses revealed that negative and positive relationship emotional schemas had a significant correlation with the domestic violence domains and its total score and with neuroticism and extraversion. Conclusions: According to the present findings, RESS can be utilized in research and clinical practice.

Abstract Background Studies of psychological distress in Sierra Leone have typically used measures which were developed for use in other contexts, and which often have not been adapted or validated for use in Sierra Leone. This has resulted in a lack of reliable information about the patterns of psychological distress within the population, which is a barrier to the development of effective and appropriate mental health services. The aim of the study was to develop a locally-appropriate measure of psychological distress for Sierra Leone. Methods The new measure consists of two instruments: the Sierra Leone Psychological Distress Scale (SLPDS) and a gendered measure of ability to carry out daily tasks—a Function scale—as an indication of the severity of distress. A three-phase mixed methods exploratory sequential study was conducted. Phase 1 was item generation and testing, leading to the development of a set of potential items for both instruments. Phase 2 was a small pilot study (N = 202) leading to the selection of the final set of items for both measures. Phase 3 was a validation phase where the SLPDS and the Function scale were administered with a larger sample of 904 respondents. Item analysis was used to assess the internal consistency of the scales, and Exploratory Factor Analysis to explore the properties of the SLPDS. Results Exploratory factor analysis using the principal axis factoring with an oblique rotation identified a three-factor structure for the 18-item SLPDS. Internal consistency for the SLPDS (Cronbach’s alpha = 0.89) and three subscales was good (Cronbach’s alpha > 0.73). The internal reliability of the male and female versions of the Function scale was also found to be acceptable (Cronbach’s alpha = 0.90 for the female scale and 0.79 for the male scale). Conclusions Together the SLPD and Function scales provide a locally-validated tool which will enable government bodies and local and international non-governmental organisations in Sierra Leone to assess mental health and psychosocial needs. This will support both effective service provision and the evaluation of initiatives designed to improve mental health and psychosocial wellbeing.

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.

Η παρούσα διδακτορική διατριβή αποσκοπεί στο να καταγράψει την ικανοποίηση των επισκεπτών από τις παρεχόμενες υπηρεσίες στα θεματικά μουσεία της Ελλάδας, την πρόθεση συμπεριφοράς των επισκεπτών και κατά πόσο τεχνικές του τουριστικού μάρκετινγκ λαμβάνουν χώρα στα θεματικά μουσεία. Έγινε μία προσπάθεια να καταγραφούν οι απόψεις των ανθρώπων των θεματικών μουσείων και η αντίληψή τους σχετικά με το τουριστικό μάρκετινγκ, οι αντιλήψεις των επισκεπτών σχετικά με την εμπειρία που βιώνουν σε ένα θεματικό μουσείο, ο βαθμός ικανοποίησης τους, η υφιστάμενη κατάσταση που επικρατεί στα θεματικά μουσεία της χώρας και οι ενδεχόμενες αλλαγές που μπορούν να προκύψουν με απώτερο σκοπό την αύξηση της επισκεψιμότητας. Ένα αξιοσημείωτο της παρούσας έρευνας, είναι ένας σημαντικός αριθμός προσωπικών συνεντεύξεων με κατοίκους περιμετρικά των μουσείων που ερευνήθηκαν και η προσπάθεια καταγραφής των απόψεων και αντιλήψεων τους για τα μουσεία αυτά.Διενεργήθηκε επίσης μία ποσοτική έρευνα σε επισκέπτες θεματικών μουσείων της χώρας μας αλλά και στο ανθρώπινο δυναμικό που εργάζεται σε πολιτιστικούς οργανισμούς, καθώς και εκπαιδευτικούς. Διακρίνοντας τα μουσεία σε δημόσια και ιδιωτικά, σημαντική ήταν η καταγραφή απόψεων ότι στα περισσότερα δημόσια θεματικά μουσεία τα οποία λειτουργούν κάτω από την επίβλεψη του δημόσιου φορέα, δεν υπάρχουν συχνά δυνατότητες για καινοτομία και πρωτοτυπία. Τα πορίσματα της παρούσας διδακτορικής διατριβής είναι αρκετά σημαντικά λόγω της έλλειψης προηγούμενης έρευνας επάνω στα θεματικά μουσεία της Ελλάδας, από την οπτική του μάρκετινγκ και την αναγκαιότητα αυτού. Η πλειονότητα των ανθρώπων των θεματικών μουσείων με τους οποίους ήρθα σε επαφή, εντοπίζουν την ανάγκη για τεχνικές τουριστικού μάρκετινγκ στα μουσεία καθώς όλοι αντιλαμβάνονται ότι οι επισκέπτες αναζητούν ποιοτικότερες ψυχαγωγικές επιλογές, έχουν περισσότερες απαιτήσεις επισκεπτόμενοι ένα θεματικό μουσείο και ευελπιστούν σε μία βιωματική και διαδραστική εμπειρία που θα τους μείνει αξέχαστη. Σε αυτό το εγχείρημα, συνεργός είναι τα ποικίλα οπτικοακουστικά μέσα των νέων τεχνολογιών που ενισχύουν το βιωματικό χαρακτήρα της επίσκεψης και ερευνώνται στη διατριβή. Η παρούσα διατριβή αποτελεί μία πρώτη προσπάθεια χαρτογράφησης των τεχνικών τουριστικού μάρκετινγκ που χρησιμοποιούν τα θεματικά μουσεία της χώρας , τις σημαντικές ιδιαιτερότητες του τουρισμού που έχουν άμεση επίδραση στην επισκεψιμότητα των θεματικών μουσείων και τέλος προτάσσει ενέργειες και τεχνικές μάρκετινγκ για να δημιουργηθεί ένας ενάρετος κύκλος πολιτισμού - ψυχαγωγίας - οικονομίας. Για την επεξεργασία των δεδομένων της ποσοτικής έρευνας χρησιμοποιήθηκε το στατιστικό εργαλείο SPSS, αναλύθηκαν τα ευρήματα της Διερευνητικής Ανάλυσης Παραγόντων (Exploratory Factor Analysis) και των τεστ αξιοπιστίας με τον δείκτη Cronbach’s Alpha, εφαρμόζοντας και την μέθοδο Μοντελοποίησης Δομικών Εξισώσεων (Structural Equation Modeling, SEM) για τον έλεγχο των ερευνητικών υποθέσεων. Οι ερευνητικές υποθέσεις δημιουργήθηκαν έπειτα από ενδελεχή έρευνα μοντέλων που εφαρμόστηκαν σε προηγμένες μουσειολογικά χώρες, όπως η Ισπανία, η Ιταλία, η Ολλανδία κ.α. και μπορούν να ληφθούν σοβαρά υπόψιν στο κοινωνικό-οικονομικό περιβάλλον της Ελλάδας. Απώτερος στόχος του ερευνητικού μοντέλου είναι εάν ο επισκέπτης θα οδηγηθεί σε μελλοντική επίσκεψη (revisit ) ή θα αποτελέσει ο ίδιος κινητή διαφήμιση word-of-mouth του μουσείου που επισκέφθηκε.Η έρευνα αποτελεί οδηγό για μελλοντικές έρευνες που θα πλαισιώσουν ή θα συμπεριλάβουν τα θεματικά μουσεία για νέες μελέτες, όπως για παράδειγμα πολιτιστικές διαδρομές και είναι ένα χρήσιμο εργαλείο που έρχεται να καλύψει το ερευνητικό κενό που υπάρχει γύρω από το είδος των μουσείων αυτών.

Relevance. Nowadays the researchers commonly use a limited set of standard procedures and statistical coefficients when develop psychometric instruments and investigate their structure. The routine using of such procedures without taking into account the specific features of the psychometric scales can lead to incomplete or even inadequate results. In this context detailed consideration of the structure of psychometric instruments seems to be important and it may demand various non-standard ways of statistical analysis. Objectives. To conduct detailed analysis of the results of two intelligent subtests at the item level and to assess the sufficiency and adequacy of using standard methods for estimation of reliability and structural validity for these subtests. Methods. We analyze the data collected in intelligence testing of a large sample of respondents (11335 young adults). The respondents passed the KR-3 battery. In this study we examine in detail the structure of the subtests “Syllogisms” and “Analogies”. Specifically, we estimated the reliability of the scales by the Cronbach’s alpha coefficient, and the structure at the item level using the confirmatory factor analysis. Results and conclusions. Estimation of the reliability of the scales by Cronbach’s alpha coefficient showed importance of taking into account the time limitation, which is commonly used in intelligence tests. On the other hand, a detailed analysis of each subtest items made it possible to find out an additional factor which was not originally proposed in the factor structure. This is factor of higher-order abilities of abstract analysis, whilst the subtest originally aimed at estimation of the special abilities. Confirmatory factor analysis showed improvement of fit when this factor was added. The results allow to conclude that the researcher may miss the important properties of scales if not making a detailed analysis of testing procedures and the structure of subtest at the item level, and so may draw incomplete or inadequate conclusions about their psychometric properties

Η παρούσα μελέτη είχε σκοπό να αποτυπώσει τις συνθήκες που διέπουν τo παιδικό ποδόσφαιρο στην Ελλάδα και να διερευνήσει τους παράγοντες που σχετίζονται με την ανάπτυξή του. Αρχικά διερευνήθηκε η κατάσταση που επικρατεί στο ελληνικό ποδόσφαιρο. Αποτυπώθηκε ο αριθμός των σωματείων που δραστηριοποιούνται σε κάθε ποδοσφαιρική κατηγορία καθώς και τα Τμήματα υποδομής που λειτουργούν σε ολόκληρη την ελληνική επικράτεια. Τα αποτελέσματα έδειξαν ότι το έτος 2010-2011 στις διοργανώσεις της Ελληνικής Ποδοσφαιρικής Ομοσπονδίας και των Ποδοσφαιρικών Ενώσεων συμμετείχαν 3.352 αθλητικά σωματεία ποδοσφαίρου και συγκεκριμένα: στην Α΄ Εθνική κατηγορία (Super League) συμμετείχαν 16 σωματεία, στη B΄ Εθνική κατηγορία (Football League) 18 σωματεία, στη Γ΄ Εθνική κατηγορία (Football League II) 33 σωματεία, στη Δ΄ Εθνική κατηγορία 157 σωματεία και στα τοπικά πρωταθλήματα των Ποδοσφαιρικών Ενώσεων 3.128 σωματεία. Από αυτά τα 1.293 σωματεία διαθέτουν τμήματα εκμάθησης ποδοσφαίρου. Ακολούθως κατασκευάστηκε ένα ερωτηματολόγιο για να αποτυπωθούν οι παράγοντες που επηρεάζουν την ποδοσφαιρική εκπαίδευση στα Τμήματα υποδομής. Στην παρούσα έρευνα πήραν μέρος 806 προπονητές που εργάζονταν σε 391 Τμήματα υποδομής ποδοσφαίρου. Τα Τμήματα αυτά επιλέχτηκαν με σταδιακή τυχαία δειγματοληψία από τα 1293 τα οποία λειτουργούν στους 51 νομούς της Ελληνικής Επικράτειας. Οι στατιστικές αναλύσεις που χρησιμοποιήθηκαν ήταν: 1) οι μέθοδοι περιγραφικής στατιστικής για την περιγραφή των υποομάδων του ερωτηματολογίου, 2) η μέθοδος του Cronbach’s Alpha για τον έλεγχο του βαθμού αξιοπιστίας του ερωτηματολογίου, 3) η διερευνητική παραγοντική ανάλυση (exploratory factor analysis) για τον έλεγχο της δομικής εγκυρότητας του ερωτηματολογίου, 4) το κριτήριο συσχέτισης 2 ποιοτικών χαρακτηριστικών χ2 για τη στατιστική αξιολόγηση της διαφοράς των αναλογιών των ερωτήσεων σχετικά με την οργάνωση της εκπαίδευσης. Όπου δεν πληρούνταν οι προϋποθέσεις εφαρμογής, έγινε χρήση του αντίστοιχου ελέγχου Fisher’s exact test, 5) η ανάλυση διακύμανσης κατά μια κατεύθυνση (ANOVA) με τους 5 παράγοντες που συνθέτουν τον σχεδιασμό της εκπαίδευσης για τη διερεύνηση των παραμέτρων που επηρεάζουν την ποδοσφαιρική εκπαίδευση, και 6) η Πολυμεταβλητή ανάλυση διακύμανσης (MANOVA) για να ελεγχθεί: α) αν τα κοινωνικά χαρακτηριστικά του προπονητή (εκπαιδευτικό επίπεδο, προπονητικό δίπλωμα, επάγγελμα, εισόδημα, εμπειρία) παίζουν σημαντικό ρόλο στον σχεδιασμό της εκπαίδευσης στο παιδικό ποδόσφαιρο, και β) αν η έδρα, η κατηγορία που αγωνίζεται το αθλητικό σωματείο και τα κοινωνικά χαρακτηριστικά του προπονητή παίζουν σημαντικό ρόλο στον σχεδιασμό της εκπαίδευσης στο παιδικό ποδόσφαιρο. Σύμφωνα με τα αποτελέσματα της έρευνας το ερωτηματολόγιο που αναπτύχθηκε μπορεί να αποτελέσει ένα μεθοδολογικό εργαλείο που αποτυπώνει έγκυρα και αξιόπιστα την ποιότητα της παρεχόμενης εκπαίδευσης στα Τμήματα υποδομής ποδοσφαίρου. Οι προπονητές είναι πολύ ικανοποιημένοι με τους παράγοντες «Υποδομή» και «Εκπαιδευτικοί στόχοι», μέτρια ικανοποιημένοι από τον παράγοντα «Διδακτικοί στόχοι» και πολύ λίγο ικανοποιημένοι από τους παράγοντες «Χρόνος» και «Προσωπικό» των προγραμμάτων εκμάθησης ποδοσφαίρου. Επίσης προκύπτει ότι: α): το δίπλωμα του προπονητή επηρεάζει την εκπαίδευση των παιδιών ηλικίας 6-18 ετών στο ποδόσφαιρο, β) οι προπονητές που έχουν προπονητικό δίπλωμα, τίτλους σπουδών πανεπιστημιακού επιπέδου και περισσότερη εμπειρία αξιολογούν πιο θετικά την ποδοσφαιρική εκπαίδευση. Επιπλέον φαίνεται ότι η γεωγραφική περιοχή που έχει έδρα το σωματείο επηρεάζει την ποιότητα της ποδοσφαιρικής εκπαίδευσης. Τέλος φαίνεται ότι η ποδοσφαιρική κατηγορία που συμμετέχει ένα ποδοσφαιρικό σωματείο επηρεάζει τον σχεδιασμό και την οργάνωση της ποδοσφαιρικής εκπαίδευσης για τα παιδιά.

Ethical Climate Questionnaire

Background: An ethical climate has been described as a working climate embracing shared perceptions about morally correct behaviour concerning ethical issues. Various ethical climate questionnaires have been developed and validated for different contexts, but no questionnaire has been found concerning the ethical climate from an inter-professional perspective in a healthcare context. The Swedish Ethical Climate Questionnaire, based on Habermas’ four requirements for a democratic dialogue, attempts to assess and measure the ethical climate at various inter-professional workplaces. This study aimed to present the construction of and to test the psychometric properties of the Swedish Ethical Climate Questionnaire. Method: An expert group of six researchers, skilled in ethics, evaluated the content validity. The questionnaire was tested among 355 healthcare workers at three hospitals in Sweden. A parallel analysis (PA), an exploratory factor analysis and confirmatory factor analysis were performed. Ethical considerations: The participants included in the psychometric analysis were informed about the study, asked to participate in person and informed that they could withdraw at any time without giving any reason. They were also assured of confidentiality in the reporting of the results. Findings: The parallel analysis (PA) recommended one factor as a solution. The initial exploratory factor analysis with a four-factor solution showed low concordance with a four-factor model. Cronbach’s alpha varied from 0.75 to 0.82; however, since two factors only consisted of one item, alpha could not be reported. Cronbach’s alpha for the entire scale showed good homogeneity (α = 0.86). A confirmatory factory analysis was carried out based on the four requirements and showed a goodness-of-fit after deleting two items. After deletion of these items, Cronbach’s alpha was 0.82. Discussion: Based on the exploratory factor analysis, we suggest that the scale should be treated as a one-factor model. The result indicates that the instrument is unidimensional and assesses ethical climate as a whole. Conclusion: After testing the Swedish Ethical Climate Questionnaire, we found support for the validity and reliability of the instrument. We found the 10-item version of Swedish Ethical Climate Questionnaire satisfactory. However, we found no support for measuring different dimensions and, therefore, this instrument should be seen as assessing ethical climate as of whole.

AbstractClassrooms can be noisy and are challenging listening environments for children with auditory processing disorder (APD). This research was undertaken to determine if the Listening Inventory for Education-UK version (LIFE-UK) can differentiate children with listening difficulties and APD from their typically developing peers.To investigate reliability and validity of the student and teacher versions LIFE-UK questionnaire for assessing classroom listening difficulties.Cross-sectional quantitative study comparing children with listening difficulties with typically developing children.In total, 143 children (7–12 yr) participated; 45 were diagnosed with APD. Fifteen participants with reported listening difficulties who passed the APD test battery were assigned to a “listening difficulty” (LiD) group. Eighty three children from nine classrooms formed a Control group.Children and teachers completed the LIFE-UK questionnaire student and teacher versions. Factor analysis was undertaken, and item reliability was assessed using Cronbach’s alpha. Teacher and student ratings were compared using Spearman correlations. Correlations between LIFE-UK ratings and APD test results were also investigated.Factor analysis revealed three factors accounting for 60% of the variance in the Control group LIFE-UK ratings. After removing six items with low factor loadings, a shortened seven-item version with three factors accounted for 71.8% of the variance for the student questionnaire; Cronbach’s alpha indicated good internal reliability for this seven-item version of the student questionnaire. Factors were also derived for the teacher questionnaire. Teacher and student ratings were correlated when participant groups were combined. LIFE-UK ratings correlated weakly with some APD measures, providing some support for the questionnaire validity.The results support the use of either the 13- or 7-item student and the teacher versions of the LIFE-UK to evaluate classroom listening and functional consequences of APD. Factor analysis resulted in groupings of items reflecting differences in listening demands in quiet versus noise for the student questionnaire and attentional versus class participation demands for the teacher questionnaire. Further research is needed to confirm the robustness of these factors in other populations.
