Εισαγωγή: Η αυξανόμενη παχυσαρκία στην εφηβεία αποτελεί ένα παγκόσμιο πρόβλημα δημόσιας υγείας. Σκοπός της παρούσας μελέτης του προγράμματος «Feeding Exercise Trial in Adolescents (FETA)» είναι: α) στην αρχική φάση, η διερεύνηση του επιπολασμού της παχυσαρκίας των εφήβων και των γονέων τους στην περιοχή της Λάρισας και β) στη δεύτερη φάση, η αξιολόγηση της αποτελεσματικότητας του προγράμματος FETA.Μέθοδος: Στην αρχική φάση το δείγμα αποτελούνταν από 816 έφηβους, ηλικίας 12-18 ετών και τους γονείς τους από 17 γυμνάσια και λύκεια της Λάρισας. Κατά τις επισκέψεις στα σχολεία πραγματοποιήθηκαν ανθρωπομετρικές μετρήσεις καθώς και μετρήσεις αρτηριακής πιέσεως. Οι μαθητές συμπλήρωσαν ερωτηματολόγια που περιλάμβαναν τα δημογραφικά χαρακτηριστικά και την τροποποιημένη μορφή των ερωτηματολογίων Parental Authority Questionnaire (PAQ), του Parent-Initiated Motivational Climate Questionnaire-2 (PIMCQ-2) και του Family Eating and Activity Habits Questionnaire (FEAHQ). Οι γονείς συμπλήρωσαν ένα ερωτηματολόγιο δημογραφικών και ανθρωπομετρικών στοιχείων καθώς και το FEAHQ. Στη δεύτερη φάση 181 υπέρβαροι και παχύσαρκοι έφηβοι (ηλικίας 12-16 ετών) πήραν μέρος και χωρίστηκαν σε τρεις ομάδες μελέτης («Διατροφή & Άσκηση», «Άσκηση» και ελέγχου), ενώ 150 έμειναν μέχρι το τέλος των 3 μηνών του προγράμματος αλλά και 3 μήνες μετά το πέρας αυτού. Η ομάδα «Άσκηση» εφάρμοσε ένα 45λεπτό πρόγραμμα εκπαίδευσης στοχευόμενο στη φυσική άσκηση, ενώ η ομάδα που εφάρμοσε το πρόγραμμα «Διατροφή & Άσκηση» πριν το πρόγραμμα της φυσικής άσκησης συμμετείχε σε 10-15λεπτές συνεδρίες στοχευόμενες στη διατροφή που μπορούσαν να τις παρακολουθήσουν και οι γονείς. Όλοι οι έφηβοι συμμετείχαν σε ανθρωπομετρικές μετρήσεις, σε κινητικές δοκιμασίες και καταγραφή οικογενειακών συνηθειών (FEAHQ) μαζί με τους γονείς τους. Το Epi Info χρησιμοποιήθηκε για την καταγραφή των δεδομένων και το στατιστικό πακέτο SPSS για τη στατιστική ανάλυση. Καταγράφηκε ο μέσος όρος αλλά και οι συχνότητες ποσοτικών μεταβλητών. Με τον δείκτη Cronbach’s alpha coefficient καταγράφηκε η αξιοπιστία των ερωτηματολογίων PAQ, PIMCQ και FEAHQ. Δεχτήκαμε ως βαθμό σημαντικότητας p-value λιγότερο από 0.05 (p<0.05). Αποτελέσματα: Τα αποτελέσματα της αρχικής φάσης έδειξαν ότι το 75.2% των εφήβων είχαν φυσιολογικό Δείκτη Μάζας Σώματος (ΔΜΣ), το 2.6% των εφήβων ήταν λιποβαρή, το 18% υπέρβαρα και 4.2% παχύσαρκα. Όσον αφορά τους γονείς, το 76.3% των πατέρων και 39.2% των μητέρων ήταν υπέρβαροι ή παχύσαρκοι. Η πολυπαραγοντική ανάλυση λογιστικής παλινδρόμησης έδειξε ότι το υπερβολικό βάρος ή η παχυσαρκία στην εφηβεία σχετίζεται με το φύλο (αγόρι), το ΔΜΣ της μητέρας, το μορφωτικό επίπεδο της μητέρας, τη συνήθεια να τρώνε ενώ χωρίς να πεινάνε, τη συνήθεια να τρώνε το φαγητό στα δωμάτια εκτός από την κουζίνα και τον τύπο του πατέρα που κινητοποιείται με την ανησυχία για την αποτυχία. Τα αποτελέσματα της δεύτερης φάσης (κλινική δοκιμή-παρέμβαση) έδειξαν ότι οι ομάδες «Άσκηση» και «Διατροφή & Άσκηση» μείωσαν σημαντικά (p < 0.001) το μέσο όρο του ΔΜΣ (-1.1, 95% CI: 1.3,-0.8 και -1.4, 95% CI: -1.7, -1.2 αντίστοιχα), της περιφέρειας μέσης, της συστολικής και διαστολικής αρτηριακής πίεσης, τους παλμούς ανά λεπτό και της κινητικής δοκιμασίας των 50μ. σπριντ στους 3 μήνες, ενώ η μεγαλύτερη μείωση του ΔΜΣ παρατηρήθηκε στους 6 μήνες ( -2.3, 95% CI: -2.6, -2,0 και -3.1, 95% CI: -3.3, -2.8). Σημαντικές αλλαγές στην συνολική βαθμολογία FEAHQ επιτεύχθηκαν μόνο στην ομάδα «Διατροφή & Άσκηση», τόσο στους 3 όσο και στους 6 μήνες.Συμπεράσματα: Η κλινική δοκιμή FETA είχε ως αποτέλεσμα σημαντική βελτίωση των τιμών του ΔΜΣ σε υπέρβαρους και παχύσαρκους εφήβους, αύξησης της δραστηριότητας τους και βελτίωσης των διατροφικών συνήθειών των οικογενειών, όπου διατηρούνται και 3 μήνες μετά την ολοκλήρωση του προγράμματος. Συζήτηση: Οι μελλοντικές παρεμβάσεις πρέπει να εστιάζουν τόσο στους γονείς όσο και στα παιδιά, λαμβάνοντας υπόψη το ρόλο της γονικής μέριμνας, για την πρόληψη της παχυσαρκίας των εφήβων.

The purpose of this study is to develop a valid and reliable TPACK (technological pedagogical content knowledge) scale based on the core components of TPACK framework in order to measure teacher-educators’ TPACK. For this purpose, 46 statements were developed and tested by 5-point Likert type scale. Data were collected from 642 teacher educators working in different colleges of education under different universities in state of Punjab. The collected data was analyzed by using SPSS 22.0 software. The Exploratory Factor Analysis (EFA) was carried out in order to investigate the factor structure of the scale. EFA resulted in six factors named as Pedagogical skills, Creative thinking skills, Ethics, Instructional design, Innovativeness and Virtual learning environment. The Cronbach’s Alpha coefficient for the whole scale was calculated as .848. The KMO value was calculated as .889 and the Bartlett’s Test of Sphericity examined (chi-square = 17196.73; df = 1035), which is significant (P-Value<.001). Based on result and in comparison with the Cronbach’s alpha coefficient values for other TPACK surveys in the literature as a whole and for their sub-components the TPACK scale established here can be said to have a high level of reliability in terms of its factors and as a whole.

Introduction: Due to occurrence of fires in process industries, it is vital to implement crisis management systems in these industries and keep the readiness of these systems high. The purpose of this study is to evaluate the readiness of emergency response teams to deal with a possible fire in a process industry. Methods: This descriptive-analytical study was performed in 2019 in a gas refinery with a statistical population of 200 people. A questionnaire with Likert scale was designed through library and field studies for all teams participating in the firefighting process. Content Validity Ratio (CVR) and Content Validity Index (CVI) were used to measure validity and Cronbach's alpha coefficient was used to measure the reliability of the questionnaires. The collected data were entered into SPSS software version 24 and statistical analysis was performed at 95% significance level using One Way ANOWA test. Results: The results showed that the readiness of this refinery to deal with a possible fire was 68.3%, which among the 11 teams participating in this process, the security team with 53.48% had the lowest and the logistics team with 77.5% had the highest preparedness (P-value = 0.028). The highest CVR was for the safety team questionnaire (0.77) and the highest Cronbach's alpha coefficient was for the liaison team (0.92).  Conclusion: The results of this study showed that the readiness of this gas refinery in the firefighting process is satisfactory, although some teams, including the security team, are less prepared than other teams. Therefore, it is better to take intervention measures as soon as possible, including providing the necessary equipment and providing various trainings and maneuvers in order to increase the readiness of the teams.

The study aimed to carry on the process of the cultural adaptation of the Italian Spine Youth Quality of Life Questionnaire (ISYQOL) into Polish (ISYQOL-PL). The a priori hypothesis was: the ISYQOL-PL questionnaire is reliable and appropriate for adolescents with a spinal deformity. Fifty-six adolescents (mean age 13.8 ± 1.9) with idiopathic scoliosis (AIS) with a mean Cobb angle 29.1 (±9.7) and two with Scheuermann juvenile kyphosis (SJK) with a kyphosis angle 67.5 (±17.7) degrees were enrolled. All patients had been wearing a corrective TLSO brace for an average duration of 2.3 (±1.8) years. The Institutional Review Board approved the study. The cross-cultural adaptation of the ISYQOL-PL was performed following the guidelines set up by the International Quality of Life Assessment Project. The reliability was assessed using internal consistency (the Cronbach’s alpha coefficient) and test–retest reliability (intraclass correlation coefficient ICC2.1, CI = 95%); moreover, floor and ceiling effects were calculated. The internal consistency was satisfactory (Cronbach’s alpha coefficient 0.8). The test–retest revealed high reliability with the value of ICC2.1 for the entire group 0.90, CI (0.84 to 0.94). There was neither floor nor ceiling effect for the ISYQOL-PL overall score. The ISYQOL-PL is reliable and can be used in adolescents with spinal deformity.

Abstract: Introduction: Clinical teaching is based on a real work environment, in professional practice settings, such as health services and units, under the supervision of the preceptor. Providing medical teachers with an assessment of their teaching skills is a powerful tool for improving clinical learning for students in training. In this context, the EFFECT (Evaluation and Feedback for Effective Clinical Teaching) questionnaire was developed by Dutch researchers in 2012 for teacher evaluation, being validated based on the literature about medical teaching in the workplace and incorporates the skills of the Canadian competency-based medical curriculum. Objective: To translate and cross-culturally adapt into Brazilian Portuguese and to validate the EFFECT questionnaire for teacher evaluation by Medical students. Method: Cross-cultural adaptation with the following steps: initial translation of the English version, synthesis of translated versions, back-translation, creation of a consensual version in Brazilian Portuguese, with adaptation, review, and analysis of content validity by an expert committee, pre-test with retrospective clarification interview, and reliability analysis by factorial analysis and internal consistency test (Cronbach’s alpha coefficient). Result: In the translation and back-translation stages, the disagreements were related to the use of synonyms and none of the items were modified in terms of their understanding, but in terms of adaptation into the Brazilian context. The evaluation of the expert committee showed the versions maintained the semantic and idiomatic equivalences of the content. Eighty-nine students participated in the pre-test. The internal consistency of the EFFECT questionnaire in Brazilian Portuguese was excellent for all domains, with Cronbach’s alpha coefficient ranging from 0.82 to 0.94. Conclusion: The translated and adapted version of the EFFECT questionnaire into Brazilian Portuguese is equivalent to the original instrument and has evidence of high validity and reliability, being able to constitute a national tool to evaluate the efficiency of clinical medicine teaching.

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

Abstract Introduction. The paper presents the adaptation of the Iowa Satisfaction with Anesthesia Scale to the conditions in Polish hospitals.Methods. The process of cultural adaptation of the Iowa Satisfaction with Anesthesia Scale was divided into three stages. The first stage was to formulate the Polish version of the ISAS. Secondly, the scale was used in the group of patients who were diagnosed with a maxillofacial injury and underwent surgical procedure. The final stage evaluated the psychometric features of the Polish version of the ISAS.Results. 195 questionnaires were completed correctly and they were subject to further analysis. The questionnaires were collected from patients residing at the Maxillofacial Surgery Clinical Ward who were operated under a general anaesthesia due to a maxillofacial trauma. The average result of the satisfaction with anaesthesia in a studied group was 0.77 (scale from -3 to +3) M=2, SD=2.41. The Cronbach’s alpha coefficient calculated for 11 multiple choice questions was 0.598. It would be possible to increase the Cronbach’s alpha coefficient if question no. 1 (I vomited or felt nauseous) was eliminated from the test (maximum 0.601). Every item on the scale had significant influence on the general result (p=0.0001).Conclusions. Polish version of the Iowa Satisfaction with Anesthesia Scale meets the criteria of the psychometric equivalence with the original version. It is necessary to continue research using Polish version of the ISAS to provide a constant verification of reliability and accuracy of the research tool.

BACKGROUND: Given the increased rate of divorce, it is important to analyse the characteristics of divorce applicants. The theory of planned behaviour (TPB) can provide a suitable framework to predict, explain, and/or change the behaviours. In Iran, no instrument can be found, based on health education models, to investigate divorce petition filing as a behaviour.AIM: This study was conducted to design a questionnaire on withdrawal of divorce petition based on the TPB and estimate its validity and reliability.MATERIAL AND METHODS: A qualitative study was conducted in 27 participants involved in the divorce process using directed content analysis. The face and content validity of 58 items, drawn from the qualitative study, were evaluated by 10 experts. The reliability was estimated using Cronbach’s alpha coefficient. The SPSS version 16 was used to analyse data.RESULTS: Estimates of the face and content validity (quantitative and qualitative), revealed that of the 58 items, 48 were valid based on four of the constructs of the TPB. Cronbach’s alpha coefficient was also derived greater than 0.6.CONCLUSION: The designed questionnaire, whose validity and reliability was confirmed in this study, can be used in similar studies. However, the social and cultural differences and their related effects should be considered.

Background: Stroke causes a wide variety of clinical manifestations that may have a negative impact on quality of life. Therefore, it is very important to use specific instruments for measuring quality of life in individuals who suffered a stroke. The aim of this study was to develop a psychometrically validated Spanish version of the Newcastle stroke-specific quality of life measure (NEWSQOL). Methods: A psychometric validation of the Spanish version of the NEWSQOL questionnaire was carried out in 159 patients. The reliability (intraclass correlation coefficient and Cronbach’s alpha coefficient), validity (factorial analysis and Spearman’s coefficient), feasibility (response rate), and the ceiling and floor effects were calculated. Results: Internal consistency showed that Cronbach’s alpha coefficient was 0.93. The test–retest reliability was high or excellent for all domains (range 0.71–0.97 p < 0.001). The response rate of the questionnaire was 100% and the average administration time was 20.5 (±7.2) min. No ceiling effect was detected and two domains (pain and vision) may have a significant potential for floor effect. Construct validity showed that all the variables are important enough to keep them all in the questionnaire. Concerning convergent construct validity, a high correlation was found with the Nottingham Health Profile, the Barthel Index, and the Modified Rankin Scale. Conclusion: The Spanish version of the NEWSQOL questionnaire is reliable, valid, and feasible to evaluate quality of life in the Spanish population.

Empathy is considered to be associated with better patient compliance, satisfaction, and clinical outcomes. The aim of the study is to measure and examine empathy among a sample of undergraduate medical students of Bangladesh. It was a cross-sectional study and all the medical students of first through fifth year enrolled at Chattagram Maa-O-Shishu Hospital Medical College during the study period of 2014 were surveyed. Participants anonymously completed the Jefferson Scale of Empathy Medical Student version translated into Bengali language, a valid and reliable 20-item self-administered questionnaire. Principal component factor analysis with varimax rotation and Cronbach’s alpha coefficient were calculated to check validity and reliability of the scale. ANOVA was used to examine the differences in empathy between gender, academic years, and specialty preferences. The mean empathy score was 110.41 ± 13.59. Cronbach’s alpha coefficient was 0.88. There were significant associations between gender and empathy scores. The level of empathy in medical students gradually increases after clinical training in medical college. A nonsignificant difference was found between empathy scores and specialty preferences. It is suggested that the medical curriculum in Bangladesh should include more extensive program to promote empathy and other humanistic values among the medical students.
