The model of evaluation developed in this research focuses on evaluation of:  planning, processing, and results, so the model is called the P2HT evaluation model. The P2HT evaluation model is developed on eight steps: (1) preliminary research, (2) designing model, (3) developing prototype model, (4) trying-out with limited number of samples, (5) revising, (6) trying-out with larger samples, (7) constructing final model, and (8) disseminating. The prototype model was tried-out at Yogyakarta Open University Regional Center in three stages. The readability was tested to 15 experts, 12 practitioners, and 55 students. The content validity was measured by a series of discussion forum involving evaluation experts and distance education experts, in the form of face-to-face meetings, FGDs, as well as emails. The construct validity was analyzed by using Confirmatory Factor Analysis and Exploratory Factor Analysis, while the reliability was analyzed for each dimension employing the Alpha analysis per dimention. The path analysis was used to analyze the causality relationship among variables in the P2HT evaluation model especially in stage 3 try-out. The results of the study indicate that: (1) the P2HT evaluation model is comprehensive, valid, practical, easy to use, and has a high level of readability, (2) all instruments are valid and reliable, (3) the management of program, self-directed learning, place and facilities of tutorial, tutorial process, and students’ satisfaction have an effect on the students’ achievement. Among the five variables, the process of tutorial has given the greatest effect 58%.Keywords: evaluation model, face-to-face tutorial, instrument, validity and reliability

Σκοπός της παρούσας μελέτης ήταν η διερεύνηση οικογενειακών και σχολικών παραγόντων που σχετίζονται με τα προβλήματα συμπεριφοράς μαθητών δημοτικού σχολείου και των πρακτικών διαχείρισής τους στο πλαίσιο της οικογένειας και του σχολείου στην ημιαστική περιοχή του Γαζίου, του Νομού Ηρακλείου Κρήτης. Ειδικότερα, επρόκειτο για μια μελέτη περίπτωσης που βασίστηκε στη συλλογή εμπειρικών και ποιοτικών δεδομένων. Στο εμπειρικό της μέρος, πραγματοποιήθηκε συγκριτική έρευνα ανάμεσα σε 55 μαθητές με προβλήματα συμπεριφοράς (ερευνητική ομάδα) και σε 55 μαθητές χωρίς προβλήματα συμπεριφοράς (ομάδα ελέγχου), που ανήκαν στις τρεις τελευταίες τάξεις του δημοτικού σχολείου, με τη χορήγηση 7 συνολικά ερωτηματολογίων: 1) Ερωτηματολόγιο TRF για Εκπαιδευτικούς (32 Ερωτήσεις) Παιδιών Ηλικίας 6-18 ετών (Achenbach & Rescorla, 2003), 2) Εργαλείο Ψυχοκοινωνικής Προσαρμογής: Κλίμακα Αυτοαναφοράς για Μαθητές 10-12 ετών (Χατζηχρήστου, Πολυχρόνη, Μπεζεβέγκης, & Μυλωνάς, 2008), 3) Εργαλείο Ψυχοκοινωνικής Προσαρμογής: Κλίμακα Εκπαιδευτικού για Παιδιά 7-12 ετών (Χατζηχρήστου, Πολυχρόνη, Μπεζεβέγκης, & Μυλωνάς, 2008), 4) PARQ/Parental Acceptance-Rejection/Short Form (Rohner, 2004), 5) TARQ/Teacher’s Acceptance-Rejection/Short Form (Rohner, 2004), 6) SFI/Self Report Family Inventory, Version II (Beavers & Hampson, 1990) και 7) Το Ερωτηματολόγιο της Τάξης μου για το Δημοτικό Σχολείο (ΤΕΤ/Βούλγαρης & Ματσαγγούρας, 2004). Το ποιοτικό μέρος περιελάμβανε τη μελέτη 12 συνολικά περιπτώσεων μαθητών με προβλήματα συμπεριφοράς και τη διεξαγωγή ημιδομημένων συνεντεύξεων στους ίδιους τους μαθητές, στους γονείς και στους δασκάλους τους (36 συνολικά συνεντεύξεις), όπου κατά κύριο λόγο διερευνήθηκαν: οι πρακτικές διαχείρισης που υιοθετούνται από τους γονείς και τους δασκάλους απέναντι στα προβλήματα συμπεριφοράς των μαθητών, ο τρόπος που αυτές βιώνονται από τους μαθητές, οι αντιδράσεις που τους προκαλούν και η αποτίμηση της αποτελεσματικότητάς τους κι από τις τρεις πλευρές. Η ανάλυση των εμπειρικών δεδομένων της έρευνας, η οποία βασίστηκε στο Στατιστικό Πακέτο IBM SPSS Statistics Version 20, περιελάμβανε Διμεταβλητές Σχέσεις, Διερευνητική Παραγοντική Ανάλυση/Exploratory Factor Analysis (EFA), Επιβεβαιωτική Παραγοντική Ανάλυση /Confirmatory Factor Analysis (CFA) και Ανάλυση Διαδρομών/Path Analysis, όπου εξετάστηκε η προσαρμογή 9 διαφορετικών Μοντέλων Διαδρομών/Path Models. Οι συνεντεύξεις της ποιοτικής μελέτης αναλύθηκαν με τη μέθοδο της ανάλυσης περιεχομένου. Σύμφωνα με τα βασικότερα ευρήματα του εμπειρικού μέρους: 1) η αυτοαντίληψη του μαθητή διαδραματίζει τον πιο σημαντικό ρόλο στην πρόβλεψη των προβλημάτων συμπεριφοράς στο συγκεκριμένο πληθυσμό μαθητών, συγκρινόμενη τους άλλους παράγοντες ψυχοκοινωνικής του ανάπτυξης (κοινωνική, συναισθηματική και σχολική επάρκεια), 2) η εχθρότητα/επιθετικότητα του πατέρα και της μητέρας προβλέπουν σε σημαντικό βαθμό την παρουσία προβλημάτων συμπεριφοράς στον πληθυσμό αυτό, 3) η στάση αποδοχής/απόρριψης των δύο γονιών συνάδει μεταξύ τους, με τη στάση του πατέρα να επηρεάζει τη στάση της μητέρας στις ήπιες μορφές απόρριψης και τη στάση της μητέρας να επηρεάζει τη στάση του πατέρα στις πιο έντονες μορφές απόρριψης, ενώ η αντίστοιχη στάση του δασκάλου επηρεάζεται από τη στάση του πατέρα, 4) η ζεστασιά/στοργή της μητέρας διαδραματίζει τον πιο σημαντικό ρόλο στην πρόβλεψη των προβλημάτων συμπεριφοράς και της σχολικής επάρκειας των μαθητών αυτών, συγκρινόμενη με τις άλλες διαστάσεις μητρικής και πατρικής αποδοχής/απόρριψης, ενώ τόσο η συνοχή, όσο και η σύγκρουση της οικογένειας προβλέπουν με τον ίδιο τρόπο την υγιή/ικανή οικογενειακή λειτουργία και 5) η αδιαφοροποίητη απόρριψη του δασκάλου προβλέπει στο μεγαλύτερο βαθμό την παρουσία προβλημάτων συμπεριφοράς στο συγκεκριμένο πληθυσμό μελέτης συγκριτικά με τις άλλες διαστάσεις αποδοχής/απόρριψης του δασκάλου, ενώ τόσο η συνεκτικότητα, όσο και η διενεκτικότητα της τάξης προβλέπουν με τον ίδιο τρόπο την ικανοποίηση από τη λειτουργία της τάξης. Ακόμα, βάσει των κυριότερων δεδομένων του ποιοτικού μέρους της έρευνας: 1) υπερισχύουν οι αρνητικές γονικές και εκπαιδευτικές πρακτικές αντιμετώπισης της προβληματικής συμπεριφοράς των μαθητών (π.χ. ανέβασμα του τόνου της φωνής, τιμωρίες, φυσική/σωματική επιθετικότητα), σύμφωνα με τις αναφορές των ίδιων των μαθητών, 2) οι πρακτικές των γονιών κι ειδικά της μητέρας βιώνονται από τους μαθητές ως πιο σκληρές από εκείνες των δασκάλων τους και συνήθως συνδέονται με τη μη συμμόρφωσή τους, σε αντιδιαστολή με εκείνες του δασκάλου, στις οποίες οι μαθητές συμμορφώνονται, 3) οι αρνητικές γονικές πρακτικές προκαλούν συναισθήματα στενοχώριας, φόβου και θυμού στους μαθητές, 4) οι αποτελεσματικές γονικές και εκπαιδευτικές πρακτικές ομόφωνα συνδέονται, κατά την αντίληψη των τριών πλευρών, με θετικούς κυρίως τρόπους προσέγγισης των μαθητών (π.χ. συζήτηση, ενθάρρυνση, χιούμορ), ενώ οι αναποτελεσματικές πρακτικές με αποκλειστικά αρνητικούς τρόπους προσέγγισής τους (π.χ. ανέβασμα του τόνου της φωνής, τιμωρία, επίπληξη) και 5) οι μαθητές ζητούν από τους γονείς και τους δασκάλους τους να σταματήσουν τις αρνητικές πρακτικές και να αυξήσουν τις θετικές πρακτικές που εφαρμόζουν. Πρόκειται για δεδομένα που συμβάλλουν σημαντικά στη βαθύτερη κατανόηση του συγκεκριμένου πληθυσμού μελέτης, η οποία συνιστά αναγκαία προϋπόθεση και συνθήκη για το σχεδιασμό και την υλοποίηση εστιασμένων/αποτελεσματικών προληπτικών προγραμμάτων και παρεμβάσεων σχετικά με την προβληματική/αντικοινωνική (επιθετική και παραβατική) συμπεριφορά των προ-εφήβων μαθητών.

The aim of this study is to determine the factors that affect the development of bureaucratic knowledge and skills of farmers in rural areas. To achieve this aim, a questionnaire was administered face-to-face to 110 farmers. The survey was conducted in the central villages of Tokat Province in 2013. Exploratory factor analysis and confirmatory factor analysis were used to determine the factors that affect the development of farmers’ knowledge and skills regarding bureaucratic procedures. The exploratory factor analysis generated a structure with 4 factors and 10 variables. These factors which explained 76.063% of the total variance, and their reliability coefficients were determined as cooperation tendency (0.803), bureaucratic procedure experience (0.701), level of benefit from government support (0.900) and immediate environment communication (0.601). According to the results of the confirmatory factor analysis, the fit index values were 0.938 for GFI; 0.934 for CFI and 0.913 for NFI. The fact that the RMSEA and CMIN/DF coefficients were also consistent and significant indicates that the results fit the theory. The fact that the intended goodness-of-fit index values of these coefficients were significant also indicates that the results fit the theory. Thus, the factors that affect the bureaucratic knowledge and skills of farmers in the rural areas of Tokat Province were found to be: getting involved in agricultural organizations, the experience of performing formal procedures in public offices, attempts to benefit from agricultural support and immediate environment communication.

AbstractThe study attempted to analyse the concept of spectators’ motives at mixed martial arts (MMA) events in Poland. In addition, we investigated the relation between motives and sports media consumption. The sample consisted of 273 people attending three similar, regional MMA events. Exploratory factor analysis was used to refine the structure of motives. Confirmatory factor analysis showed a reasonable fit of the obtained model (RMSEA = 0.41). Using ANOVA we found three significant differences in assessment of motives, based on gender. The factor of aesthetics and knowledge was ranked the highest for men and women. Men rated drama and violence, while women perceived socializing and crowd experience, and drama, as the following factors. Path analysis indicated that these motives explained 56% of variance in media consumption for men and 57% for women. The findings showed that the motive of vicarious achievement was the main predictor of media consumption for men, while aesthetics and knowledge were the key predictors for women. The results and ideas for further research are discussed.

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.

General Psychological Distress

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.

Weight Stigmatization

The present study was intended to develop a scale to measure perceived weight stigmatization among people with obesity. The study was conducted in five steps. In first step, three focus group discussions were conducted with female obese university students to get the first-hand information related to weight stigmatization. Step two involved four interviews which were conducted with male obese university students to collect detailed information about weight stigmatization experiences of men. Step three included content analysis of qualitative data for item generation. In step four, judge’s opinion was taken, and a committee approach was carried out to select the items for the initial form of the scale. Items for final form of the scale were selected through exploratory factor analysis and confirmatory factor analysis in step five. For exploratory factor analysis, 150 university students (men = 61, women = 89) were included in the sample, whereas, for confirmatory factor analysis, another group of students (men = 78, women = 72) participated in the study. Principal Component Factor Analysis revealed three meaningful structures including Self-Perception, Perceived Social Rejection, and Perceived Impact containing 43 items. Confirmatory factor analysis confirmed this factor structure and all 43 items possessed factor loadings greater than .40. Moreover, results indicated that perceived weight stigmatization had high internal consistency (Cronbach’s alpha = .96) with three subscales having internal consistency .95, .83, and .92 respectively. Therefore, Perceived Weight Stigmatization Scale turned out to be a reliable and valid instrument for measuring perception of weight stigma in adults with obesity.

Abstract Background: Effective monitoring of cognitive behaviour therapy (CBT) competence depends on psychometrically robust assessment methods. While the UK Cognitive Therapy Scale – Revised (CTS-R; Blackburn et al., 2001) has become a widely used competence measure in CBT training, practice and research, its underlying factor structure has never been investigated. Aims: This study aimed to present the first investigation into the factor structure of the CTS-R based on a large sample of postgraduate CBT trainee recordings. Method: Trainees (n = 382) provided 746 mid-treatment audio recordings for depression (n = 373) and anxiety (n = 373) cases scored on the CTS-R by expert markers. Tapes were split into two equal samples counterbalanced by diagnosis and with one tape per trainee. Exploratory factor analysis was conducted. The suggested factor structure and a widely used theoretical two-factor model were tested with confirmatory factor analysis. Measurement invariance was assessed by diagnostic group (depression versus anxiety). Results: Exploratory factor analysis suggested a single-factor solution (98.68% explained variance), which was supported by confirmatory factor analysis. All 12 CTS-R items were found to contribute to this single factor. The univariate model demonstrated full metric invariance and partial scalar invariance by diagnosis, with one item (item 10 – Conceptual Integration) demonstrating scalar non-invariance. Conclusions: Findings indicate that the CTS-R is a robust homogenous measure and do not support division into the widely used theoretical generic versus CBT-specific competency subscales. Investigation into the CTS-R factor structure in other populations is warranted.

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.

Background: Low-income adolescents’ physical activity (PA) levels fall below current recommendations. Perceived barriers to physical activity (PBPA) are likely significant predictors of PA levels; however, valid and reliable measures to assess PA barriers are lacking. This manuscript describes the development of the PBPA Survey for Low-Income Adolescents. Methods: A mixed-method approach was used. Items identified from the literature and revised for clarity and appropriateness (postcognitive interviews) were assessed for test–retest reliability with 74 adolescents using intraclass correlation coefficient. Items demonstrating low intraclass correlation coefficients or floor effects were removed. Both exploratory factor analysis and confirmatory factor analysis analyses (n = 1914 low-income teens) were used to finalize the scale; internal consistency was assessed by Cronbach’s alpha. Concurrent validity was established by correlating the PBPA with the PA questionnaire for adolescents using a Spearman correlation. Results: The exploratory factor analysis yielded a 38-item, 7-factor solution, which was cross-validated by confirmatory factor analysis (comparative-fit index, nonnormed fit index = .90). The scale’s Cronbach’s alpha was .94, with subscales ranging from .70 to .88. The PBPA Survey for Low-Income Adolescents’ concurrent validity was supported by a negative PA questionnaire for adolescents’ correlation values. Conclusion: The PBPA Survey for Low-Income Adolescents can be used to better understand the relationship between PBPA among low-income teens. Further research is warranted to validate the scale with other adolescent subgroups.
