patient health questionnaire Greek Language validation and subscale factor structure
Comprehensive Psychiatry, 2012Co-Authors: Maria Karekla, Nataliya Pilipenko, Jonathan M. FeldmanAbstract:This study aimed to assess the reliability, validity, and factor structure of the Greek translation of the Patient Health Questionnaire (PHQ) in a sample of Cypriot, Greek-speaking university students. This is the first study to examine PHQ psychometric properties in Greek and to investigate the factor structure of the PHQ subscales. A total of 520 participants (73.9% women; M(Age) = 21.57; SD, 4.94) completed the PHQ and assessment tools used for convergent validity analysis. Patient Health Questionnaire was translated and culturally adapted according to international standards. Overall, PHQ subscales in Greek Language demonstrated good internal consistency (mean Cronbach α = .75, P < .001) and convergent validity with the following: Alcohol Use Disorders Identification Test, Beck Depression Inventory, Psychiatric Diagnostic Screening Questionnaire (panic disorder, somatization, bulimia, and binge eating), and Anxiety Sensitivity Index (overall mean, r = 0.52; P < .001). The relation between the PHQ subscale diagnoses and functional impairment, as assessed by the 12-item Health Survey 12, was comparable with the original validation results for all subscales except alcohol. The depression, alcohol, and anxiety subscales exhibited single-factor structures. Subscales assessing eating disorders, panic disorder, and somatization difficulties exhibited 2-, 3-, and 4-factor structures, respectively. Overall, PHQ subscales demonstrated good psychometric properties, with the exception of the subscale examining problematic alcohol use. Overall, PHQ demonstrates good reliability, validity, and appropriate factor structure in a Greek-speaking college population. Psychometric research is needed on the Greek PHQ in primary care settings.

school policy on teaching and school learning environment direct and indirect effects upon student outcome measures
Educational Research and Evaluation, 2012Co-Authors: Leonidas Kyriakides, Bert P. M. CreemersAbstract:School policy on teaching and the school learning environment (SLE) are the main school factors of the dynamic model of educational effectiveness (Creemers & Kyriakides, 2008). A longitudinal study in which 50 primary schools, 108 classes, and 2369 students participated generated evidence supporting the validity of the dynamic model. This article reports the results of a re-analysis of the data of this study in order to search for direct and indirect effects of school factors included in the model. Using multilevel structural equation modelling techniques, indirect effects of school policy on teaching and SLE upon achievement in mathematics and Greek Language are demonstrated. Implications of findings are drawn. Comparing the results of the multilevel direct and indirect effect model with those from using a multilevel regression model, we demonstrate the importance of choosing appropriate conceptual models and using relevant methodological approaches to understand the dynamic nature of educational effecti...

can schools achieve both quality and equity investigating the two dimensions of educational effectiveness
Journal of Education for Students Placed at Risk (jespar), 2011Co-Authors: Leonidas Kyriakides, Bert P. M. CreemersAbstract:This article investigates the extent to which schools can achieve both equity and quality. Data emerged from two effectiveness studies in teaching mathematics and Greek Language, which were conducted to test the validity of the dynamic model of educational effectiveness. Separate multilevel analyses for each subject were conducted and it was found that the effectiveness status of schools does not change significantly when the two dimensions (equity and quality) are used to measure their effectiveness status in each subject. Changes in their effectiveness status in terms of each dimension of measuring effectiveness were also examined. In each subject, schools that were found to improve their effectiveness status in terms of the equity dimension were also found to improve their effectiveness status in terms of the quality dimension. Moreover, no school that was found to improve its effectiveness status in terms of one dimension had declining effectiveness in terms of the other dimension of effectiveness. Im...

the influence of school leadership styles and culture on students achievement in cyprus primary schools
Journal of Educational Administration, 2010Co-Authors: Andreas Kythreotis, Petros Pashiardis, Leonidas KyriakidesAbstract:Purpose – This study aims to examine the validation of both the model of direct effects and the model of indirect effects of principals' leadership on student academic achievement.Design/methodology/approach – A longitudinal study was conducted in which 22 schools, 55 classes and 1,224 Cypriot primary students participated. Specifically, achievements in Greek Language and Mathematics were assessed at the beginning and at the end of the same school year. Moreover, leadership style of school principals and teachers as well as school and classroom culture was measured.Findings – The findings provide some empirical support for the model of direct effects of principals' leadership on student academic achievement. Moreover, student achievement gains were found to be related with five factors at the school level: the principals' human resource leadership style and four dimensions of organizational culture. At the classroom level, three dimensions of learning culture significantly influence student achievement in...

drawing from teacher effectiveness research and research into teacher interpersonal behaviour to establish a teacher evaluation system a study on the use of student ratings to evaluate teacher behaviour
The Journal of Classroom Interaction, 2005Co-Authors: Leonidas KyriakidesAbstract:This paper presents results of a study attempting to identify the extent to which teacher effectiveness research and research into teacher interpersonal behavior can help us collect valid and reliable evaluative data from students about their teacher behavior. The major findings of teacher effectiveness research are outlined and the process that was followed in order to design questionnaire measuring student views of their teacher behavior in the classroom is presented. The main findings of research into teacher interpersonal behavior are also presented, and the process that was followed in order to translate, to Greek, the Questionnaire on Teacher Interaction (QTI) and examine its content validity is described. A stratified sample of 38 primary schools in Cyprus was selected and the two questionnaires were administered to all year-6 students (N=1973) from each class (N=92) of the school sample. Evidence supporting the reliability, discriminate validity, and construct validity of each questionnaire is provided. Data collected from most of the scales of each questionnaire were associated with student achievement gains in both cognitive (Mathematics and Greek Language) and affective outcomes of schooling. Implications of findings for the development of a teacher evaluation system based on the main findings of teacher effectiveness research and research into teacher interpersonal behavior are drawn. Suggestions for further research are also provided.

The factor structure of Greek personality adjectives.
Journal of personality and social psychology, 2005Co-Authors: Gerard Saucier, Stelios Georgiades, Ioannis Tsaousis, Lewis R. GoldbergAbstract:Personality descriptors—3,302 adjectives—were extracted from a dictionary of the modern Greek Language. Those terms with the highest frequency were administered to large samples in Greece to test the universality of the Big-Five dimensions of personality in comparison to alternative models. One- and 2-factor structures were the most stable across variable selections and subsamples and replicated such structures found in previous studies. Among models with more moderate levels of replication, recently proposed 6- and 7-lexical-factor models were approximately as well replicated as the Big Five. An emic 6-factor structure showed relative stability; these factors were labeled Negative-Valence/Honesty, Agreeableness/Positive Affect, Prowess/Heroism, Introversion/Melancholia, Even Temper, and Conscientiousness.

τhe impact of cognitive dimension of tam perceived usefulness and perceived ease of use in teachers attitudes towards ict s integration in teaching ancient Greek Language in lower secondary school the case of greece
European Journal of Education Studies, 2018Co-Authors: Ilias LoumosAbstract:This study aims to delve deeper into Greek teachers’ attitudes towards the use of ICT in ancient Greek teaching, in Greek public lower secondary schools, representing an attempt to identify the Cognitive Dimension of Greek teachers’ of ancient Greek Language (philologists) attitudes. More specifically, the main goal is to examine Perceived Ease of Use and Perceived Usefulness concerning teachers’ of ancient Greek degree of familiarity with ICTs and the degree of effectiveness in ICT’s integration in teaching and learning practice. As for Perceived Ease of Use this research study investigates, in respect of teachers’ attitudes: a) ICT’s degree of personal and educational use, b) Self-perception degree towards ICT’s use, and c) Degree of ability in ICT’s teaching integration. As for Perceived Usefulness this study investigates: a) ICT’s usefulness degree in achieving learning objectives, b) Usefulness degree in teaching application of ICT, and c) ICT’s effectiveness degree as for teachers’ role. Broadly speaking, the research findings reveal that teachers of ancient Greek, use ICTs to do their lesson preparation and planning, but they are not used to integrating technology in teaching practices. Yet, Greek teachers of ancient Greek Language consider -as important barrier/factor to use ICT in teaching and learning process- their lack of effective training in ICT’s teaching use. As a result, they show low self-perception degree -as for ICT’s use- and become more and more reluctant to adopt new technologies in teaching and learning procedure. Moreover, the findings stress that Greek philologists firmly believe that ICT can be used as an innovative tool of teaching and learning procedure, motivating teachers and increasing their interest in teaching approach. However, New Educational Technology is not applied in teaching practice and teachers of ancient Greek Language -denied to ‘escape’ from traditional ways of teaching- prefer conventional/traditional teaching practices in ICT’s use to modern/contemporary teaching methods, achieving mainly cognitive goals. To sum up: a) gender, b) years of experience in teaching, c) specific knowledge in teaching ancient Greek Language with ICT, and d) appropriate in-service training on ICTs have a significant impact on teachers’ of ancient Greek attitudes, regarding whether or not ICT’ s use enhance: a) traditional teaching style, b) linguistic literacy, c) critical literacy, d) sociocultural literacy.

Supporting and Consulting Infrastructure for Educators during Distance Learning Process: The Case of Russian Verbs of Motion
Springer Verlag, 2020Co-Authors: Kalita O., Gartsov A., Pavlidis G., Nanopoulos P.Abstract:This paper presents a supporting and consulting infrastructure (methods and tools) assisting educators during the distance learning process. The main focus is on the information sketching a student profile. Having identified all possible behaviors, the proposed infrastructure allows the development of probabilistic distribution models of the emerging educational events. The determination of probabilities is estimated by applying data mining techniques and then using the method of maximum entropy. As an example, the process of learning the semantic structure of motion verbs in Russian and Greek Language is taken. Emphasis is given to those cases where verbs structures match entirely, partially overlap, as well as those whose semantic sizes are specific, characterize either the Russian, or solely the Greek Language
