Introduction: To date, a universal validated and specific tool for assessing coronavirus disease 2019 (COVID-19) stigma among healthcare workers is lacking. We adapted a SARS stigma scale that was developed using the Berger HIV scale for use as a COVID-19 stigma scale and evaluated its psychometric properties among Egyptian physicians. Methods: We administered the 17-item SARS stigma scale in an anonymous online questionnaire among 509 Egyptian physicians recruited via convenience sampling during a cross-sectional study in June 2020. Exploratory factor analysis was performed on half of the sample. Confirmatory factor analysis of the resulting model was done using structural equation modeling on the other half. Scale reliability was examined using Cronbach’s alpha for internal consistency. Convergent construct validity was assessed using regression models to examine the association between the adapted COVID-19 stigma scale and relevant factors. Results: Exploratory factor analysis yielded 16 items (E16-COVID19-S) that supported a three-factor structure: personalized stigma (8 items); concerns of disclosure and public attitudes (5 items); and negative experiences (3 items). Cronbach’s α was 0.909 for the total scale and 0.907, 0.663, and 0.789 for the three subscales. E16-COVID19-S was confirmed to have good model fit (comparative fit index = 0.964; root mean squared error of approximation = 0.056). E16-COVID19-S was independently associated with physicians’ younger age, lower qualification, working in an isolation hospital, and self-stigma, whether the scale was treated as categorical or continuous. Conclusions: E16-COVID19-S exhibited good internal consistency and construct validity among this sample of Egyptian physicians. These adequate psychometric properties make the E16-COVID19-S scale appropriate for use by researchers and practitioners.

Purpose The brand equity pyramid is a theory that explains how people develop loyalty and an attachment to a brand. The purpose of this study is to test whether the predictions made by the theory hold when applied to the brand of ParticipACTION, a Canadian non-profit organization that promotes active living. A secondary objective was to test whether this theory predicted intentions to be more physically active. Design/methodology/approach A research agency conducted a cross-sectional, online brand health survey on behalf of ParticipACTION. Exploratory factor analysis and confirmatory factor analysis established the factor structure. Structural equation modeling was used to test the hypothesized model. Findings A nationally representative sample of Canadian adults (N = 1,191) completed the survey. Exploratory factor analysis and confirmatory factor analysis supported a hypothesized five-factor brand equity framework (i.e. brand identity, brand meaning, brand responses, brand resonance and intentions). A series of structural equation models also provided support for the hypothesized relationships between the variables. Practical implications Though preliminary, the results provide a guide for understanding the branding process in the activity-promotion context. The constructs identified as being influential in this process can be targeted by activity-promotion organizations to improve brand strength. A strong organizational brand could augment activity-promotion interventions. A strong brand may also help the organization better compete against other brands promoting messages that are antithetical to their own. Originality/value This is the first study to test the brand equity pyramid using an activity-promotion brand. Results demonstrate that the brand equity pyramid may be useful in this context.

Abstract Background Diabetes foot self-care is one of the self-management behaviors of diabetic patients leading to a reduction in the incidence of pressure ulcers and amputation. Having a valid, reliable, simple and comprehensive tool is essential in measuring the self-care behavior of diabetic patients. The aim of this study was to evaluate the psychometric properties of the Farsi version of the diabetes foot self-care bahavior scale (DFSBS) in Iran. Methods In this cross-sectional and methodological study, 500 patients with type 2 diabetes were recruited by convenience sampling. Construct validity was assessed by exploratory factor analysis (over 300 patients) and confirmatory factor analysis (over 200 patients). Internal consistency was calculated by Cronbach’s alpha coefficient and its stability was calculated by intraclass correlation coefficient (ICC). Results In the exploratory factor analysis, two self-care factors related to feet and shoes were extracted which had specific values of 38.49 and 1.24, respectively, and were able to account for 56.22% of the total self-care variance of diabetes foot. Confirmatory factor analysis had excellent fit model. The internal consistency and ICC of the whole instrument were 0.83 and 0.791 (95% CI: 0.575–0.925; P < 0.001), respectively. Conclusions The Farsi version of DFSBS (F-DFSBS) has good validity and reliability, and due to its appropriate psychometric properties, this tool can be used in future studies.

Ως μελέτη περίπτωσης ορίστηκε η Σχολή Επιστημών της Διοίκησης και της Πολυτεχνικής Σχολής, που εδρεύουν στο νησί της Χίου και αποτελούνται από τέσσερα Πανεπιστημιακά Τμήματα, Για τη διερεύνηση του πρωταρχικού σκοπού της παρούσας μελέτης έγινε χρήση της Εξερευνητικής (Exploratory Factor Analysis) και Επιβεβαιωτικής (Confirmatory Factor Analysis) Παραγοντικής Ανάλυση και οι σχέσεις μεταξύ των εργαλείων του μοντέλου μελετήθηκαν με τη χρήση του Μοντέλου Δομικών Εξισώσεων (Structural Equation Modeling).Για τη δημιουργία του Μοντέλου Δομικών Εξισώσεων χρησιμοποιήθηκαν μεταβλητές, που σύμφωνα με την ανασκόπηση της βιβλιογραφίας, έχουν σχέση με τις κοινωνικές επιπτώσεις από τη χρήση του Facebook και του Instagram στη φοιτητική κοινότητα. Συγκεκριμένα, χρησιμοποιήθηκαν ως μεταβλητές οι: α) χρήσεις και ικανοποιήσεις β) κοινωνικό κεφάλαιο γ) αίσθηση της κοινότητας δ) κοινωνικότητα ε) η συχνότητα χρήσης του Facebook και του Instagram από τους φοιτητές/τριες και στ) ο αριθμός των «φίλων/followers» στο Facebook και το Instagram και έγινε προσπάθεια να επιβεβαιωθεί η σχέση τους. Για την διερεύνηση των ερευνητικών στόχων χρησιμοποιήθηκε ποσοτική μέθοδος έρευνας και συμμετείχαν στην έρευνα 202 φοιτητές/τριες από τα τέσσερα Πανεπιστημιακά Τμήματα.Από τα αποτελέσματα της έρευνας προκύπτει πως και οι δυο ιστοσελίδες κοινωνικής δικτύωσης χρησιμοποιούνται πολύ από τους φοιτητές/τριες για κοινωνικούς και ακαδημαϊκούς λόγους, παρουσιάζοντας όμως διαφοροποιήσεις, στη συχνότητα χρήσης αλλά και στα κίνητρα για τη χρήση τους. Η πλειονότητα των φοιτητών/τριών συνδέεται τις περισσότερες φορές στο Instagram παρά στο Facebook και το Facebook χρησιμοποιείται περισσότερο για ακαδημαϊκούς λόγους από το Instagram που χρησιμοποιείται περισσότερο για κοινωνικούς λόγους. Επιπλέον, τα αποτελέσματα της παρούσας έρευνας αντιπαρατίθενται στον προβληματισμό που υποστηρίζει ότι η ενασχόληση με το Facebook και το Instagram απομακρύνει τους φοιτητές από σημαντικά στοιχεία της πανεπιστημιακής ζωής και συνδέεται με τη δημιουργία ψευδών κοινοτήτων και επιφανειακών σχέσεων. Αντιθέτως, υποστηρίζουν πως σε πανεπιστημιακές μικρές κοινότητες, όπου υπάρχει μεγάλη διάδραση σε κοινωνικό και ακαδημαϊκό επίπεδο εκτός διαδικτύου, η διάδραση αυτή μεταφέρεται και στις ιστοσελίδες κοινωνικής δικτύωσης, όπως είναι το Facebook και το Instagram και επιδρά θετικά στο κοινωνικό κεφάλαιο και την αίσθηση της κοινότητας των φοιτητών/τριών με το Πανεπιστημιακό Τμήμα φοίτησης.Λέξεις κλειδιά: Facebook, Instagram, χρήσεις και ικανοποιήσεις, κοινωνικό κεφάλαιο, αίσθηση της κοινότητας, κοινωνικότητα

The aim of this study is to adapt the Moral Integrity Scale developed by Sclenker (2008) to Turkish and conduct its psychometric analysis. The scale items were translated into Turkish by five specialists in the first place. After the language structure, culture suitability and understandability of the items were examined by the two experts, the items agreed upon were translated back to their original language by the two translation experts. After the positive evaluations of the experts, the final version of the scale items was decided. During the adaptation process of the study, data were collected from 470 people for exploratory factor analysis; from 248 people for confirmatory factor analysis and from 100 people for criterion validity. In this context, Exploratory Factor Analysis (AFA) was used to test the construct validity of the scale first. As a result of the exploratory factor analysis, it is seen that the moral integrity scale explains 52,127% of the variance as one dimension. Confirmatory factor analysis (CFA) was then performed to test the construct validity of the scale. The one-dimensional and 18-item structure of the Moral Integrity Scale was analyzed with DFA and accepted fit indices were obtained (X2 / sd = 2.745; p <.001; RMSEA = 0.061; S-RMR = 0.051; NFI = 0.929; CFI = 0.954; GFI = 0.915; RFI = 0.919). In order to calculate the scale reliability, the Cronbach Alpha (α) internal consistency coefficients and the difference between the lower and upper scores of 27% were examined. For the Moral Integrity Scale, the internal consistency coefficient Cronbach’s Alpha value was determined as 961. At the same time, the moral identity scale was used for criterion validity and a significant positive relationship was obtained with the two sub-dimensions of this scale. The total score obtained from the scale gives the person’s moral integrity score. According to all these results, it is understood that the Moral Integrity Scale has sufficient validity and reliability values.

International Posture

This study had two aims: to attempt to verify the construct validity of the measure of international posture—which refers to attitudes toward the international community—in foreign language education and to explore how international posture structurally relates to personality traits. A total of 163 Japanese undergraduate students participated in the study. To examine the first aim, exploratory factor analysis was conducted, followed by confirmatory factor analysis. Results of the exploratory factor analysis showed that three latent constructs were extracted from 23 items of the measure. Next, confirmatory factor analysis confirmed the constructs with the fit indices except the chi-square score. To investigate the second aim, structural equation modeling was used. It showed that two personality traits—openness to experience and extraversion—were strongly associated with international posture. Furthermore, our study indicated a second-order configuration structured in the verified measure in relation to the two personality traits.

Abstract Background The use of validated questionnaires to assess the perception of teamwork can be an early step in improving team training activities. Team-STEPPS® Teamwork Perception Questionnaire (T-TPQ) has been adapted and validated for hospital setting use in several countries. Due to linguistic and cultural differences, there is need to test the psychometrics of the adapted versions. However, no research have not yet assessed the psychometric properties of the Persian T-TPQ. Therefore, this study aims to assess the internal consistency reliability and construct validity of an Iranian version of the Team-STEPPS® Teamwork Perception Questionnaire (IR-T-TPQ). Methods To conduct this study, we undertook a cross-sectional survey approach between May 2020 and January 2021. In total, 404 nurses were recruited by convenience sampling technique from 10 teaching hospitals in Tabriz, Iran. Internal consistency reliability was analyzed using Cronbach’s alpha coefficient. Confirmatory factor analysis was performed to test the construct validity of the instrument. Results Cronbach’s alpha coefficients for each subscale were acceptable, ranging from 0.84 to 0.92, as well as for the total IR-T-TPQ (α = 0.96). The confirmatory factor analysis demonstrated a five-factor model, all of whose fit indices were acceptable, except for the goodness-of-fit index and normed fit index (χ2 (df) 1332 (550), p < 0.001, Normed chi-square (χ2/df) = 2.423, RMSEA = 0.059, TLI = 0.897, CFI = 0.904, AGFI = 0.814). Conclusions The psychometric properties of the IR-T-TPQ resulted in acceptable levels of internal consistency reliability and construct validity, respectively, in Iranian hospital nurses. Further study is needed to compare the teamwork level of nurses in various settings or to evaluate the effectiveness of the teamwork intervention using this validated and reliable tool.

Σκοπός της διδακτορικής διατριβής - Το μάρκετινγκ υπηρεσιών σήμερα, αποτελεί αναμφίβολα ένα πεδίο μελέτης με μεγάλο αλλά και συνεχώς αυξανόμενο ενδιαφέρον. Το μάρκετινγκ υπηρεσιών πιο συγκεκριμένα, τις τελευταίες δεκαετίες έχει συγκεντρώσει ιδιαίτερο ενδιαφέρον από ακαδημαϊκούς, ερευνητές αλλά και επιχειρήσεις αφού έχει τάχιστα μελετηθεί σε χώρους όπως ο τουρισμός, οι εξαγωγές, ο πολιτισμός, ο αθλητισμός, οι μη – κερδοσκοπικοί οργανισμοί, η εκπαίδευση και εσχάτως η ναυτιλία. Σκοπός έτσι της παρούσας διδακτορικής διατριβής είναι να ελεγχθεί το κατά πόσο το μάρκετινγκ υπηρεσιών βρίσκει εφαρμογή στο χώρο της ελληνικής ναυτιλίας και στο χώρο της τουριστικής βιομηχανίας καθώς και το βαθμό εφαρμογής των αρχών του μάρκετινγκ στο χώρο παροχής ναυτιλιακών υπηρεσιών. Αυτό θα γίνει μέσω δύο κομβικών για το μάρκετινγκ των υπηρεσιών εννοιών, αυτών του προσανατολισμού στην αγορά και της ποιότητας των προσφερόμενων υπηρεσιών. Θα εξετασθεί επίσης, ο μεσολαβητικός ρόλος της παρεχόμενης ποιότητας υπηρεσιών στη σχέση μεταξύ προσανατολισμού στην αγορά και επιχειρηματικής επίδοσης. Μεθοδολογία της διδακτορικής διατριβής – Η συλλογή πρωτογενών δεδομένων έλαβε χώρα με τη μέθοδο της προσωπικής συνέντευξης από τη μία σε ναυτιλιακές επιχειρήσεις οι οποίες λειτουργούν στην περιοχή της Αττικής και από την άλλη σε πελάτες θαλάσσιου τουρισμού (yachting). Η συνέντευξη έγινε με τη χρήση δομημένου ερωτηματολογίου σε διάστημα έξι μηνών και συγκεκριμένα κατά τους μήνες από το Νοέμβριο του 2014 έως τον Απρίλιο του 2015. Το τελικό δείγμα ανέρχεται σε 684 έτοιμα προς χρήση ερωτηματολόγια για το χώρο της ποντοπόρου ναυτιλίας και σε 102 ερωτηματολόγια για το χώρο του θαλάσσιου τουρισμού. Για τον έλεγχο της αξιοπιστίας και της εγκυρότητας του μοντέλου, έγινε η Εξερευνητική (Exploratory Factor Analysis) και Επιβεβαιωτική (Confirmatory Factor Analysis) Παραγοντική Ανάλυση και οι σχέσεις μεταξύ των εργαλείων του μοντέλου μελετήθηκαν με τη χρήση του Μοντέλου Δομικών Εξισώσεων (Structural Equation Modeling). Ευρήματα της διδακτορικής διατριβής – Τα αποτελέσματα της έρευνας που διεξήχθη έδειξαν ότι το μάρκετινγκ υπηρεσιών βρίσκει πλήρη εφαρμογή στο χώρο της ναυτιλίας. Συγκεκριμένα, τα δύο εργαλεία μελέτης του μάρκετινγκ των υπηρεσιών, ο προσανατολισμός στην αγορά και η ποιότητα των υπηρεσιών βρίσκουν εφαρμογή στο χώρο παροχής ναυτιλιακών υπηρεσιών, ενώ ταυτόχρονα η ποιότητα των υπηρεσιών αποτελεί μεσολαβητή στη σχέση ανάμεσα στον προσανατολισμό στην αγορά και την επιχειρηματική επίδοση. Στο χώρο του θαλάσσιου τουρισμού τα αποτελέσματα της έρευνας έδειξαν ότι το μοντέλο ποιότητας υπηρεσιών που επιλέχθηκε βρίσκει εφαρμογή και επιβεβαιώνει την ύπαρξη μάρκετινγκ στον κλάδο. Περιορισμοί της διδακτορικής διατριβής – Ο κύριος περιορισμός της παρούσας έρευνας και ταυτόχρονα η πρόταση για περαιτέρω μελέτη στο μέλλον είναι αφενός η σύνδεση του προσανατολισμού στην αγορά με άλλη/ ες μεταβλητή/ ες, όπως για παράδειγμα η καινοτομία (innovation) ή ο προσανατολισμός στο μέτοχο (stakeholder orientation) και αφετέρου η μελέτη του συγκεκριμένου θεωρητικού πλαισίου εκτός του Ελληνικού χώρου. Πρακτικές εφαρμογές της διδακτορικής διατριβής – Λαμβάνοντας υπόψη ότι η ναυτιλία αποτελεί πυλώνα της εθνικής οικονομίας και πηγή εργασίας και εισοδήματος για χιλιάδες ανθρώπους, η παρούσα διατριβή μέσω της έρευνας που διεξήχθη βρίσκει πρακτική εφαρμογή και ανταπόκριση στο χώρο της ελληνικής ποντοπόρου ναυτιλίας και του θαλάσσιου τουρισμού. Η εφαρμογή βασικών αρχών του μάρκετινγκ υπηρεσιών από τις ναυτιλιακές επιχειρήσεις θα οδηγήσει σε χάραξη καλύτερης και αποτελεσματικότερης στρατηγικής και οριοθέτηση συγκεκριμένων στόχων προς επίτευξη από αυτές. Πρωτοτυπία – Η παρούσα διδακτορική διατριβή είναι η πρώτη που συνδέει τον προσανατολισμό στην αγορά, την ποιότητα των παρεχόμενων υπηρεσιών και την επιχειρηματική επίδοση στο χώρο της ναυτιλίας καθώς και η πρώτη που επιχειρεί να διερευνήσει εάν η ποιότητα υπηρεσιών βρίσκει εφαρμογή στο χώρο του θαλάσσιου τουρισμού.

AbstractSaudade involves psychosocial reactions to several circumstances involving deprivation from loved people and/or familiar locations. This work concerns the development and preliminary validation of an instrument to assess general disposition to saudade, the Porto Saudade Scale (PSS). Three studies were conducted which indicated that the PSS has favorable psychometric properties. Exploratory factor analysis of the PSS demonstrated a single latent saudade factor. The confirmatory factor analysis showed that the single latent model of the PSS is adequate and possesses good internal consistency. As expected, the data also supported the convergent, discriminant, and external validity of the PSS. Saudade was more frequently reported among females than among males. These results suggest the validity of the PSS and emphasize that it is a brief measure with strong psychometric evidence for assessing saudade.
