The purpose of this study is to examine the measurement invariance of TIMSS mathematics test for eighth grade across school location and the supervising authority (Ministry of Education, UNRWA) in Jordan. To achieve this, the researcher used the analytical descriptive approach to analyze the test results for Jordanian 8th graders who participated in the TIMSS study in 2011. Specifically, the responses of 547 students to 34 items in booklet eight and nine were analyzed. Seven items were excluded because the skewness index is ​​greater than 2 and the kurtosis index is greater than 7. The data of the remaining 27 items were analyzed by using Confirmatory Factor Analysis (CFA) and Multiple Groups Confirmatory Factor Analysis (MGCFA) through the statistical program (AMOS 22). To judge the suitability of the test factorial structure the following goodness-of-fit indices in Structural equation modeling (SEM) were used: Chi Square (χ2) test was a statistically significant value of 468.167 and a good comparison index was CFI statistically significant value of 0.934 which is greater than 0.80 and the square of the mean root error approx. The results showed that there is no Configural invariance according to the location of the school (countryside, city), and the values ​​of the χ2 were a statistical function and its value is 822.858 and a good comparison index CFI is a statistical function and its value is 0.918 which is greater than 0.80 and the mean square root of the approximate error RMSEA is a statistic function and its value is 0.024 which is less than 0.08 and a root index The mean of the standard residual squares of SRMR is statistically significant and its value is 0.0408 which is less than 0.09. The results showed that there is no Metric (or weak) invariance according to the location of the school (countryside, city), the values ​​of the χ2 were a statistical function and its value is 861.321 and a good comparison index CFI is a statistical function and its value is 0.913 which is greater than 0.80 and the average square error of the approximate error RMSEA is a statistical function whose value is 0.024 and is less than 0.08 and an index The root mean standard SRMR squares are 0.0432 and less than 0.09. The results also showed that there was no Scalar (or strong) invariance according to the location of the school (countryside, city), and the values ​​of the χ2 were a statistical function and its value was 910.730 and a good comparison index CFI was a statistical function and its value is 0.903 which is greater than 0.80 and the average square of the approximate error root RMSEA statistically significant value and 0.025 which is less than 0.08 and an index The root mean standard SRMR squared is 0.0430 and is less than 0.09. The results showed that there is no Configural invariance in the supervising authority (Ministry of Education, UNRWA), and the values ​​of the χ2 were a statistically significant value of 833.660 and a good comparison index CFI was a statistical function with a value of 0.898 which is greater than 0.80 and an average square of the root error of approximate RMSEA statistically significant value of 0.028 which is less than 0.08 The mean index of the standard residual squares SRMR is statistically significant, and its value is 0.0351, which is less than 0.09. The results showed that there is no Metric (or weak) invariance for the supervising authority (Ministry of Education, UNRWA), and the values ​​of the χ2 were a statistically significant value of 890.903 and a good comparison index CFI was a statistically significant value of 0.883 which is greater than 0.80 and the square of the mean root error of approx.

One distinguishing factor of individuals is their lifestyles. In the internet, every individual shows a different behavior while some groups have rather similar behaviors. By identifying these groups and their interests and preferences, it becomes possible to offer a product or advertising which is compatible with their wants. This leads to conveying the value presented by the producer to the consumer with high effectiveness. One source of identifying target customers or internet users is their lifestyle in internet space. The present study aims at describing and explaining internet lifestyle (e-lifestyle) of Iranian users. In particular, this study tries to find out the most common e-lifestyle of Iranian users. To this aim, 412 students involved with internet were surveyed. After estimating the construct validity of the study through confirmatory factor analysis, the mean scores of each e-lifestyle were compared by student t-test. The results revealed that Iranian users have mostly entertainment-driven e-lifestyles. The perceived importance-driven, sociability-driven, interest-driven, novelty-driven, need-driven, and uninterested or concern-driven e-lifestyles were respectively identified after that. This is the first study investigating the most common e-lifestyle among Internet users.

Aesthetic Awareness

Although environmental aesthetic has received considerable attention in recent years, there is a need for measuring and evaluating environmental aesthetic. With considering this gap in the literature, the purpose of this study is to develop the “Scale for Environmental Aesthetic Awareness” for university students and to compare students’ levels of environmental aesthetic awareness according to gender, interest in art and the place where family lives. The study group is comprised of 969 university students. For conducting the validity study of the scale, the study group was randomly divided into two: Exploratory Factor Analysis group and Confirmatory Factor Analysis group. After the elimination of outliers, 329 students remained in the EFA group and 255 students in the CFA group. As a result of EFA, 27 items were gathered under three sub-dimensions. As a result of the first-order and second-order CFA, it was seen that the model-data fit was achieved and the three-factor structure of the scale and its general structure were confirmed. The Cronbach Alpha reliability coefficient of the first, second, third sub-dimensions were calculated respectively as .80, .71 and .71. The Cronbach alfa coefficient value for the whole scale was .82. Three-way variance analysis results showed that the effects of gender and the place where family lives were not found to be statistically significant while the effect of interest in art was found to be significant; thus, the mean of the students stating they were interested in arts was found to be higher.

Objective: The aim of this cross sectional study was to assess the factor analysis of Functional Assessment of Self-Mutilation (FASM) among Iranian adolescents with non-suicidal self-injury. Method: In this study, 646 high school students, with the mean age of 16.55 ± 0.7, were selected using a multistage cluster sampling method; they completed FASM and the demographic form. Data were analyzed using the descriptive statistics, chi-square (χ2), independent sample t test, MANOVA, and confirmatory factor analyses (CFA). Results: Of the participants, 178 reported at least 1 episode of NSSI during the previous year. The mean age of the participants when they first harmed themselves was 14.64 (±1.71). Most of them reported to engage in NSSI impulsively (39.32%) and experienced little (31.5%) or moderate physical pain (31.5%) There were no significant differences between males and females in severity of NSSI, frequency of NSSI, thinking about NSSI prior to engaging in the act, and age of onset. The results of the confirmatory factor analysis supported the 4-factor model of NSSI functions suggested by Nock and Prinstine [Χ2/df = 1.84; RMSEA = 0.07; GFI = 0.82; AGFI = 0.77]. The most frequent function for engaging in NSSI was Automatic Negative Reinforcement. Conclusion: Findings of this study supported the structural validity of the FASM; thus, this tool can be useful in treatment and research contexts as a measure of NSSI functions. Moreover, this study found that adolescents engage in non-suicidal self-injury because of 4 distinct reinforcement processes. The study findings have important implications for the assessment and treatment of NSSI.

This study assessed the willingness of French youth to go and study or work for some time in another EU country. We examined three types of questions: (a) What is the overall level of willingness to go in another EU country? Does age, gender or socioeconomic status (SES) of the family influence this overall level? Which country do French youth prefer to go to? (b) Is a four-factor Push-Anti-Push-Pull-Anti-Pull model able to account for data regarding attitudes toward other countries and attitudes toward France? (c) Is this model able to predict willingness to go and study or work in another EU country, both generally and for individual countries? The overall level of willingness to go to other EU countries was not very high. Except for the United Kingdom the mean response was always located closer to the “No” pole than to the “Quite possible” pole. Gender, age, and educational level of the father did not play a role. Participants clearly preferred the United Kingdom and Spain to Germany or The Netherlands. Exploratory factor analysis showed a clearly interpretable Push-Anti-Push-Pull-Anti-Pull solution, and confirmatory factor analysis showed that this structure fits the attitudes data very well according to the usual indices. This general model, however, did not explain much of the “intent-to-go” variance. In addition, specific Pull attractiveness considerations (liking and knowing the country) played, beyond the general Push-Pull model, a notable role in the determination of willingness to go and study or work in each of the 14 EU countries.

Purpose: This study aimed to evaluate the psychometric properties of the Turkish version of ‘attitudes of nurses towards the patient’s use of TCM’ (APUTCM) and ‘communicative competence in TCM’ (CCTCM) scales. Materials and Methods: A total of 196 nurses participated in the study. A Nurse Information Form, APUTCM and CCTCM, and Holistic Complementary Alternative Medicine Questionnaire (HCAMQ) were used for data collection. Content Validity Index, exploratory factor analysis, and confirmatory factor analysis, Cronbach’s α, item-scale correlation, test-retest, and parallel forms reliability were used to evaluate validity and reliability. Results: Of the participants, 76.0% were female and the mean age was 31.6±5.8 years. Content validity indexes of the scales were over 0.87. The factor loadings were over 0.612 for both scales. Cronbach’s α values of APUTCM and CCTCM were 0.955 and 0.928 respectively. Conclusions: Both scales were found valid and reliable in Turkish society to measure the attitudes of nurses toward the patient’s use of TCM and nurses’ communicative competence in TCM.

The aim of the present study was to investigate the comparability of the mean scores of gifted students on the Jordanian version of the Overexcitabilities Questionnaire OEQII in light of gender. A cluster random sampling technique was used to collect data from 448 males and females gifted students who are enrolled in the King Abdullah II Schools of Excellence in Jordan. Results of multi-group confirmatory factor analysis clearly indicate that measurement invariance with respect to gender is untenable. Uniform measurement bias was observed in all subscales. Results suggested that the Jordanian version of OEQII failed to display scalar invariance across gender which is a requirement to scores’ comparability. Initial analyses of fitting the model to the data for each subscale suggested that the theoretical common factor structure didn’t display a reasonable fit to the data for any subscale. Results suggested that the Jordanian version of OEQII failed initially to display configural invariance across gender. In light of the results, it is recommended that the mean-level comparisons of OEQII subscale scores across gender should be interpreted with caution. Moreover, re-validating and re- standardizing of the Jordanian version of OEQII was suggested to justify mean scores comparability on its subscales.

Abstract Background Disability literacy is the ability to perceive definition of disabled person, their characteristics, difficulties in daily life and solution suggestions, their rights and false thoughts and orientations about them. The aim of the study was to develop the Disability Literacy Scale (DLS) to determine the disability literacy of medical school students with a high probability of encountering disabled people. Methods This study was conducted in 1110 medical school students in 2018-2019 academic year. By using literature 97 questions were collected. DLS was created with 22 questions by taking expert opinions. Correct answer was scored as 1, while wrong or ’do not know’ answer as 0. In order to evaluate the reliability of the scale, item total score correlation and internal consistency (Cronbach’s alpha) analyzes and exploratory and confirmatory factor analysis were used for construct validity. Results Of the 51.1% students were female and their age ranged from 17-40, the mean was 21.1±2.2. After the scale development study, the scale consisted of 14 items and 3 sub-dimensions. Scale items explain 43.21% of total variance and factor loadings ranged from 0.37-0.80. The Cronbach’s alpha coefficient was 0.61, 0.64, 0.51 for communication, health problems and social life sub-dimensions, and 0.68 for the whole scale. The fit of scale and the fit index were found to be acceptable after confirmatory factor analysis. In the last form of the scale, the score that can be taken from scale range 0-14. It was accepted that by increasing of the score, disability literacy level was increased. The mean score of students was 9.79±2.57 and the median was 10.0. The scores obtained from DLS were found to be lower in the first 3 grades (p < 0.001), low level mother and father education (p < 0.001/p=0.012) and who have not yet taken lesson about disability (p = 0.021). Conclusions DLS is a valid-reliable tool for assessing disability literacy levels of medical school students. Key messages It is essential to place disability related lessons from the earliest grades of medical school curriculum. In the literature, DLS seems the first scale about disability literacy and needs to be tested in large communities.

Fan Identity

This study is based on a sample of Spanish viewers of audiovisual fiction, seeking to understand behavior associated with fan identity. A quantitative method was used to explore the characteristics shared by viewers who define themselves as fans, as well as the existence of differences according to various sociodemographic variables. To that end, the Fan Identity Questionnaire was prepared and validated through exploratory and confirmatory factor analysis. The results confirm four types of behavior associated to media fans that, together, can explain and define fan identity with respect to the consumption of media content in Spain: experience, knowledge, collecting, and viewing. The study also shows that those viewers who define themselves as fans obtain higher values in this scale. Taking media fans into account, no significant differences were found in the mean of the Fan Identity Questionnaire based on sex, age, occupation and education and, as a result, we are able to conclude that fan identity is found in the Spanish sample regardless of the above-mentioned sociodemographic characteristics.

The present study was designed to adapt a Resilience Scale, which examines the resilience level in adolescents of India’s Hindi speaking states. In the present study, 14 items from the Resilience Scale–R25, developed by Wagnild and Young (1993), were adapted in Hindi language in the Indian context. A total 1000 adolescent students from different Hindi speaking states of India responded to the R14 scale. To test the factorial structure of the R14, an Exploratory Factor Analysis (EFA) and a Confirmatory Factor Analysis (CFA) were performed, and the internal consistency of the scale was studied. The results supported scale multidimensionality. The obtained Cronbach’s alpha revealed good internal consistency with a value of .78. Based on the psychometric properties, it is concluded that R14 is a reliable measure to assess the resilience of the adolescents of Hindi speaking states of India.
