Teachers’ teaching approaches have become an important issue in the search of quality in education and teaching because of their effect on students’ learning. Improvements in teachers’ knowledge and awareness of their own teaching approaches enable them to adopt teaching process in accordance with their students’ learning styles. The Approaches to Teaching Inventory (ATI-R), which has been developed and revised in this framework, is a scale which is effectively used to define teaching approaches in different cultures. Originally written in English, the ATI-R’s validity and reliability results were very positive. The scale’s validity and reliability analyses in different languages and cultures have produced a wide range of different results. The aim of this paper is to adapt the scale in the Turkish language. Firstly, in order to handle linguistic equivalence, data collected from 40 teachers were analyzed, and then for confirmatory and reliability analyses data were collected from 485 teachers. According to the analyses, the scale has two dimensions, and under these two dimensions there are four sub-factors. Reliability and validity results in Turkish culture are also acceptable. As a result, the scale can be administered to define teachers’ teaching approaches in Turkish samples.

Machiavvellianism is a personality trait which includes insincerity, callaousness and dishonesty. Although it was mainly studied by the literature of Psychopathology for a long time, Machiavvellianism is accepted as a trait which ordinary people has or must have, especially in competetive and extremely individualistic systems. Therefore this concept must also be studied in normal populations. Accordingly, the main aim of this research was to test the reliability and validity of Kiddie Mach (Christie, & Geis, 1970) in a Turkish speaking adolescent sample. A total of 471 adolescents (242 female, 225 male, 4 missing) were recruited for the study. The age range of the sample was 15-17 (Mean= 16.7, SD=.61). Exploratory and Confirmatory Factor Analyses indicated that scale had two dimensions. Two different analyzes were conducted to test the construct validity. First the extreme scores were compared for each subscale with t-test. The results showed that the mean differences between the upper and lower groups were significant. Second, Pearson Correlational Coefficients were analyzed between the Machiavvellianism total score which was formed as a sum of two subdimentions and narcissism, traditional ve cyberbullying, callaousness ve prosocial behaviors. All correlations were significant in expected directions. Allover results indicated that Machiavvellianism Scale was a reliable and valid measurement tool among Turkish speaking adolescents.

Communication Scale

Purpose The Communication Complexity Scale (CCS; Brady et al., 2012) was created to fill a void in measures of expressive communication skills in individuals who communicate primarily with presymbolic or early symbolic means. CCS scores reflect expressive communication observed during interactive communication contexts. Method Two studies were completed to examine the reliability and validity of the revised CCS scores. Participants in both studies had minimal verbal skills (i.e., produced less than 20 functional words). Study 1 examined interobserver agreement, test–retest reliability, and concurrent validity for 239 participants with intellectual disabilities between the ages of 3–66 years, assessed with the protocol developed at the University of Kansas (KU CCS). CCS scores were compared with scores from the Vineland Adaptive Behavior Scales–Second Edition (Sparrow, Cicchetti, & Balla, 2005) and the Communication Matrix (Rowland & Fried-Oken, 2010). Study 2 examined the reliability and concurrent validity for CCS scores derived from 110 children (chronological age = 3–9) with autism from diverse backgrounds. These children were assessed with the Early Social Communication Scale (Mundy et al., 2003). CCS scores were compared with rates of communication derived from the Early Social Communication Scale. Results CCS scores were moderately correlated with scores from existing measures of early communication. In addition, CCS scores from different raters were reliable, and test–retest scores were highly similar. Conclusions These findings support the validity and reliability of the CCS when used with individuals across a wide range of ages and with various types of disabilities. The CCS can be used in research and clinical practice to describe extant communication levels in individuals with minimal verbal skills.

Abstract Objective: In this study, the aim of the present study was to validate the Turkish version of the C-PFS after translation of the original version. Design: The data were collected via face-to-face interviews using the Turkish version of C-PFS (C-PFS-T) and a sociodemographic information form. Body mass index (BMI) was calculated by dividing body weight by the square of the height. After the adaptation of the scale to Turkish language, validity and reliability analysis were conducted for the C-PFS-T. Setting: Gülhane Training and Research Hospital Department of Child Health and Diseases Nutrition and Diet Unit in Ankara Participants: This research was conducted with volunteer children and adolescents between the ages of 9 and 16 (n 268) Results: It was concluded that the 15-item C-PFS-T was collected under 3 factors as in the original version of the child version. Cronbach α coefficient was found to be 0.878 for the scale. The confirmatory factor analysis results showed the acceptability and applicability of adapting the version of the C-PFS-T in terms of χ2/df(=3.816), AGFI(=0.931), RMSEA(=0.082) and GFI(=0.852) fit indices. C-PFS-T total score’s median value of obese group wasn’t substantially different from normal weight group. Conclusions: It was concluded that the Turkish version of the C-PFS, which provides an assessment of the hedonic hunger status of children and adolescents with 15 items and 3 subdimensions, has sufficient reliability and validity to be applied to these subjects.

The aim of this study was to describe the validity and reliability of a Turkish language version of the CoI survey developed by Arbaugh et al. (2008). Adaptation of the survey into Turkish is described. Data was obtained from 1150 students who study in different departments and take courses through online learning. The data were randomly divided into two parts: the first part was subjected to exploratory factor analysis; the second part underwent confirmatory factor analysis. Three-factor structures of the CoI framework explained 75.28% of the variance in the pattern of relationships among the items using the first split-half sample. All three presences had high reliabilities (teaching presence = .965, social presence = .953, and cognitive presence = .972). The three-factor structure of the CoI framework with teaching, social, and cognitive presences confirmed the validity of the Turkish version of the CoI survey.

Adequate Internal Consistency

The emotional experience of envy goes through different cultures. However, few instruments have been developed for its measurement. Smith et al. (1999) proposed the Dispositional Envy Scale (DES), which has shown good validity properties, stability and internal consistency in psychometric studies conducted with U.S. and Brazilian samples. This research aimed at evaluating the psychometric properties of validity and reliability of the DES with samples of participants from Cordoba, Argentina, university students (n = 399) and adults from general population (n = 316). Furthermore, the Psychological Entitlement Scale and the Subjective Happiness Scale were applied. Analysis of exploratory and confirmatory factor structure provided evidence about the unidimensionality of the scale. Evidence of adequate internal consistency was obtained. Besides, envy was positively related to entitlement and it was negatively related to subjective happiness.

The need for cognitive closure is a construct postulated by Kruglanski that explains the motivational aspects which influence decision-making and its impact on the social environment. Initially, it was assessed through a unidimensional scale, later criticized for its poor satisfactory reliability and validity. Regarding these criticisms, Pierro and Kruglanski developed a new 14-item scale to measure two dimensions, which were not previously evaluated: urgency tendency and permanence tendency. Although the Revised Test of Need for Cognitive Closure is more economical in terms of assessment time, it would be optimal to develop a reduced test that can assess faster while maintaining validity and reliability. The present research aims to reduce the Revised Test of Need for Cognitive Closure scale to the Argentinian context. To this end, we worked on a non-experimental design, assessing this scale within a sample of 690 Argentinian university students (Women = 81.16%, Men = 18.84%), and proceeded to perform reliability, as well as confirmatory factor analysis, convergent validity, and factorial invariance analysis. The results indicate a bi-factorial structure of a Need for Cognitive Closure instrument with eight items and two dimensions: urgency tendency (α = 0.76) and permanence tendency (α = 0.64), suggesting good reliability in both of them. In addition, well convergent validity was checked with other validated instruments, and finally, the factor loadings were shown to be invariant. In conclusion, it was demonstrated the reliability and validity of reducing the Revised Test of Need for Cognitive Closure in our social environment.

Abstract. Varimax rotated principal component scores (VRPCS) have previously been offered as a possible solution to the non-orthogonality of scores for the Big Five factors. However, few researchers have examined the reliability and validity of VRPCS. To address this gap, we use a lab study and a field study to investigate whether using VRPCS increase orthogonality, reliability, and criterion-related validity. Compared to the traditional unit-weighting scoring method, the use of VRPCS enhanced the reliability and discriminant validity of the Big Five factors, although there was little improvement in criterion-related validity. Results are discussed in terms of the benefit of using VRPCS instead of traditional unit-weighted sum scores.

This paper explores the influence of teaching approaches on entrepreneurial mindset of commerce, design and engineering students across 3 universities. The research presented in this paper is an initial study within a larger project looking into building ‘entrepreneurial mindsets’ of students, and how this might be influenced by their disciplinary studies. The longitudinal survey will measure the entrepreneurial mindset of students at the start of a course and at the end. Three different approaches to teaching the courses were employed – lecture and case based, blended online and class based and fully project-based course. The entrepreneurial mindset growth was surprisingly strongest within the engineering cohort, but was closely followed by the commerce students, whereas the design students were slightly more conservative in their assessments. Future study will focus on establishing what other influencing factors beyond the teaching approaches may relate to the observed change.

Abstract Introduction In Australia, health-related quality of life (HRQoL) instruments have been adopted in national population surveys to inform policy decisions that affect the health of Aboriginal and Torres Strait Islanders. However, Western-developed HRQoL instruments should not be assumed to capture Indigenous conceptualization of health and well-being. In our study, following recommendations for cultural adaptation, an Indigenous Reference Group indicated the EQ-5D-5L as a potentially valid instrument to measure aspects of HRQoL and endorsed further psychometric evaluation. Thus, this study aimed to investigate the construct validity and reliability of the EQ-5D-5L in an Aboriginal Australian population. Methods The EQ-5D-5L was applied in a sample of 1012 Aboriginal adults. Dimensionality was evaluated using Exploratory Graph Analysis. The Partial Credit Model was employed to evaluate item performance and adequacy of response categories. Area under the receiver operating characteristic curve (AUROC) was used to investigate discriminant validity regarding chronic pain, general health and experiences of discrimination. Results The EQ-5D-5L comprised two dimensions, Physiological and Psychological, and reliability was adequate. Performance at an item level was excellent and the EQ-5D-5L individual items displayed good discriminant validity. Conclusions The EQ-5D-5L is a suitable instrument to measure five specific aspects (Mobility, Self-Care, Usual activities, Pain/Discomfort, Anxiety/Depression) of Aboriginal and Torres Strait Islander HRQoL. A future research agenda comprises the investigation of other domains of Aboriginal and Torres Strait Islander HRQoL and potential expansions to the instrument.

Abstract In this contribution, a vector-autoregressive (VAR) process with multivariate t-distributed random deviations is incorporated into the Gauss-Helmert model (GHM), resulting in an innovative adjustment model. This model is versatile since it allows for a wide range of functional models, unknown forms of auto- and cross-correlations, and outlier patterns. Subsequently, a computationally convenient iteratively reweighted least squares method based on an expectation maximization algorithm is derived in order to estimate the parameters of the functional model, the unknown coefficients of the VAR process, the cofactor matrix, and the degree of freedom of the t-distribution. The proposed method is validated in terms of its estimation bias and convergence behavior by means of a Monte Carlo simulation based on a GHM of a circle in two dimensions. The methodology is applied in two different fields of application within engineering geodesy: In the first scenario, the offset and linear drift of a noisy accelerometer are estimated based on a Gauss-Markov model with VAR and multivariate t-distributed errors, as a special case of the proposed GHM. In the second scenario real laser tracker measurements with outliers are adjusted to estimate the parameters of a sphere employing the proposed GHM with VAR and multivariate t-distributed errors. For both scenarios the estimated parameters of the fitted VAR model and multivariate t-distribution are analyzed for evidence of auto- or cross-correlations and deviation from a normal distribution regarding the measurement noise.
