Abstract Background It is unlikely that applications of artificial intelligence (AI) will completely replace physicians. However, it is very likely that AI applications will acquire many of their roles and generate new tasks in medical care. To be ready for new roles and tasks, medical students and physicians will need to understand the fundamentals of AI and data science, mathematical concepts, and related ethical and medico-legal issues in addition with the standard medical principles. Nevertheless, there is no valid and reliable instrument available in the literature to measure medical AI readiness. In this study, we have described the development of a valid and reliable psychometric measurement tool for the assessment of the perceived readiness of medical students on AI technologies and its applications in medicine. Methods To define medical students’ required competencies on AI, a diverse set of experts’ opinions were obtained by a qualitative method and were used as a theoretical framework, while creating the item pool of the scale. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were applied. Results A total of 568 medical students during the EFA phase and 329 medical students during the CFA phase, enrolled in two different public universities in Turkey participated in this study. The initial 27-items finalized with a 22-items scale in a four-factor structure (cognition, ability, vision, and ethics), which explains 50.9% cumulative variance that resulted from the EFA. Cronbach’s alpha reliability coefficient was 0.87. CFA indicated appropriate fit of the four-factor model (χ2/df = 3.81, RMSEA = 0.094, SRMR = 0.057, CFI = 0.938, and NNFI (TLI) = 0.928). These values showed that the four-factor model has construct validity. Conclusions The newly developed Medical Artificial Intelligence Readiness Scale for Medical Students (MAIRS-MS) was found to be valid and reliable tool for evaluation and monitoring of perceived readiness levels of medical students on AI technologies and applications. Medical schools may follow ‘a physician training perspective that is compatible with AI in medicine’ to their curricula by using MAIRS-MS. This scale could be benefitted by medical and health science education institutions as a valuable curriculum development tool with its learner needs assessment and participants’ end-course perceived readiness opportunities.

The aim of the study was to provide evidence for the validity and reliability of the Physical Activity Affect Scale (PAAS; Lox, Jackson, Tuholski, Wasley, & Treasure, 2000) as a measure of exercise induced affect for adults with brain injuries. The PAAS is a 12-item measure of feeling states based on Russell’s (1980) conceptualization of affect. A confirmatory factor analysis was conducted on data from 193 participants with brain injuries who completed the PAAS following a single bout of exercise. Results identified four dimensions of affect (positive affect, negative affect, tranquility, and fatigue). Findings provide evidence for the validity and reliability of the PAAS as a measure of exercise induced affect for adults with brain injuries.

Abstract. The purpose of the present research was to develop and provide initial validation of the Fitness Coaching Behavior Scale (FCBS-Fit) designed for assessing perceived the quality of instructor’s behaviors in fitness group classes through the theoretical adaptation to the Coaching Model (Côté et al., 1995), originally derived from sports. In total, 618 participants of fitness group classes accepted to participate in this investigation. The purpose of the research was achieved in three phases: (1) development of the item pool and content validation of the preliminary version of the FCBS-Fit (27 items); preliminary examination of the factorial structure through exploratory factor analysis (n1 = 185) that revealed a scale with 20 items distributed by 4 factors: Technical and Positive Rapport, Exercise Planning and Prescription, Negative Rapport, and Goal Setting; (2) confirmatory factor analysis to the 4-factor model indicated adequate fit model fit, reliability and convergent and discriminant validity. In addition, a multi-group CFA indicated measurement invariance of the factorial structure across samples (n2 = 210); (3) structural equation model examined criterion validity through analysis of the relationships between the 4-factors of EPCI-Fit and enjoyment in exercise (n3 = 223). Psychometric evidence suggests that the FCBS could be used as a reliable and valid measure to assess Portuguese participant`s perceptions of the quality of instructor’s behaviors in fitness group classes.Resumen.

The aim of this study is to improve a measurement tool to evaluate the self-efficacy of Electrical-Electronics Engineering students through their basic electronics skills. The sample group is composed of 124 Electrical-Electronics engineering students. The validity of the scale is analyzed with two different methods through factor analysis and distinctiveness. To evaluate the how much each item that exists in the scale can measure the factor they belong to, item total factor correlations and corrected correlations are calculated on the data. According to the acquired values, each item and each factor in the scale are found to serve to the run-of the scale and the aim of scaling the desired facility, in a meaningful level. Moreover, analyzing the t value related to the differences between the groups of top 27% and bottom 27%, the item distinctiveness’s are researched and it is detected that the distinctiveness of both of the run-of the scale and each one of the items is high level; in other words, it is detected that each item is distinctive in the desired level. The internal consistency coefficients of the scale is calculated using two congruent halves correlations, Cronbach Alpha, Sperman-Brown formula and Guttmann split-half reliability formula. Consequently, it is concluded that the scale is a reliable and valid scale and this scale can be used to determine the basic electronics skills of the Electrical-Electronics Engineering students through their self-perceptions.

Background: Optimal management of food services in hospitals plays an important role in their performance, accelerating the patients’ recovery and increasing the level of patient satisfaction. The purpose of this study was to design a model for food service management in Iranian hospitals. Methots: This descriptive correlational study was carried out using structural equation modeling. Simple random sampling was performed and the study participants were selected among  hospital managers, nutrition experts, and environmental health experts in a hospital management conference in Tehran in September 2018. The measurement tool was a researcher-made questionnaire with confirmed construct validity and corroborated reliability through Cronbach's alpha. For data analysis, exploratory factor analysis and confirmatory factor analysis were performed via SPSS 21 and AMOS 22 software. Results: Based on the obtained model, 5 main factors affecting the management of food service sector were identified, including: health and safety factors, satisfaction factors, food waste factors, monitoring and control factors, and mechanism factors. Among these, health and mechanism factors with coefficients of 0.874 and 0.612 had the highest and the lowest effect in the management of food services in Iranian hospitals, respectively. Conclusion: According to the obtained model, various factors are effective in food management that should be considered in hospital planning. Based on this, the food health and safety dimensions are of particular importance.

Happiness is a subjective concept because every individual has a different benchmark. Nolen-Hoeksema (1998) argues that adolescents have a higher level of depression than adults, who tend to show lower levels. For that reason, there needs to be a scale to measure happiness in adolescents. This research aims to construct a happiness scale for adolescents in Yogyakarta to measure the level of happiness of adolescents in Yogyakarta in a valid way because not all measurement tools used in western cultures can be implemented in the east. This research uses a constructed psychological measurement tool. This research involves 120 adolescents aged 16-18 years in Yogyakarta. In the factorial validity test or factor analysis, there are several items separated from the initial indicators that form new indicators. These, however, are still able to uncover the aim of constructing the scale. From the 60 items proposed, five items were rejected, and 55 others were considered appropriate. Reliability testing yields a result of 0.936, meaning that the scale has a sufficient level of reliability.

Abstract: This case study determines the ability of the classroom teachers of becoming teacher-leaders in school reform in the absence of highly proficient teachers and department heads in the institution. This study aimed to explore and characterize proficient teachers as teacher-leaders at Manlilisid National High School, Javier II District, Leyte Division. This study used mixed method investigative paradigm as its research design. Quantitatively, data were gathered using the Teacher Leadership Self-Assessment (TLSA) by Katzenmeyer and Katzenmeyer (2004). It was randomly distributed to thirteen proficient teachers. Qualitatively, a semi-structured interview was done to three proficient teachers who got highest ratings in the survey. The respondents granted permission to the researcher to use the data obtained. Data were then analyzed using descriptive statistics and thematic analysis. Upon the analysis, the characteristics of the proficient teachers as teacher-leaders are evident in self-awareness, diversity, and instructional proficiency. The school can also foster teacher leadership through the determined themes - initiative and independence, partnership engagement and teamwork, and positive school environment. This study can also be a subject for further research to analyse if there is a significant difference between these types of leadership behaviour, and use the same method and instrument but is implemented in a larger population.

The aim of this study is to develop a measurement tool to measure the attitudes of pre-service teachers in science fields towards nanotechnology. For this purpose, a five-point Likert-type scale consisting of 55 items was applied to 373 pre-service teachers who are enrolled in science fields (Science, Chemistry, Biology, Physics) at the grades 1st, 2nd, 3rd, and 4th at a public university in Turkey. As a result of the exploratory factor analysis (EFA), it was determined that the scale had a 3-factor structure consisting of 24 items and the factors explained 55.854% of the total variance of the attitude variable. Verification of the model was tested by applying confirmatory factor analysis (CFA). The data used for CFA were obtained from 770 pre-service teachers who are enrolled in science fields at the grades 1st, 2nd, 3rd, and 4th at two different public universities in Turkey. The results obtained from CFA were in agreement with model obtained by EFA. Cronbach's alpha (Cr-α) reliability of the scale was calculated to be 0.926. Findings from the validity and reliability analyzes show that the scale is a valid and reliable measurement tool that can be used to measure pre-service science fields teachers’ attitudes toward nanotechnology.

The goal of this study is to develop a Guidance Qualification Scale for Preschool Teachers and examine the validity and reliability of the scale. The research was conducted with 374 teachers working in preschools in Istanbul and they were chosen by the random sampling method. Factor analysis was carried out for the construct validity of the scale. Internal consistency coefficients and test-retest reliabilities were examined and item analysis was performed for reliability studies. As a result of the factor analysis, 59 items which explained 55,989% of the total variance (Total Variance Explained 45,050%), were obtained under four factors. When the factor weights of the scale are examined, items were found to have weight values ranging from .746 to .453. Cronbach’s Alpha internal consistency coefficients of the “Preschool Teacher’s Guidance Qualifications Scale” were found to be .977 for the total scale, .954 for the "Supporting Educational Development and Interpersonal Relationships" sub-dimension, .943 for the "Supporting Individual Development and Orientation" sub-dimension, .904 for the "Self-acceptance, Support for Self and Social Development" sub-dimension and .909 for the "Recognizing Individuals, Identifying Problems and Supporting Parents" sub-dimension. Also, the test-retest reliability study of the scale was conducted with 44 teachers. According to the results of the t-test applied for differences between the average item scores of upper 27% and lower 27% groups of items on (in?) the scale, all differences were found to be significantly in favor of the upper 27% group. In light of these findings, it can be said that the “Preschool Teacher’s Guidance Qualifications Scale” can be used as a valid and reliable measurement tool in the field of education.
