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.

Academic Self Efficacy

In this study, it is aimed to develop a measurement tool with measurement validity and reliability, which can be utilized to identify the academic self-efficacy attitudes of faculty members working in the education faculty. The literature was screened during the development of the scale, the opinions of the teaching staff about the subject were taken one-on-one, and a pool of 40 items was created by making use of the previous studies related to this field. The validity and reliability of the measurement tool were analyzed on the 410-person data set obtained from the application. Exploratory Factor Analysis (EFA) was conducted with the remaining 200 data from the data set, without looking at specific criterion on the structure validity of the scale. As a result of the Exploratory Factor Analysis applied to the data obtained after the first application, 7 items were removed from the 40-item scale. It was determined that the remaining 33 items consisted of 5 sub-dimensions. The scale sub-dimensions are named as follow respectively; “Comparing yourself with other faculty members”, “Being able to combat the difficulties faced”, “Self-development”, “Effective teaching process of a course” and “Extracurricular activity”. The Cronbach’s alpha coefficient was .877 for the whole scale, and it was as follows for the sub-dimensions in respective order; .920.927.895.833 and .828. These findings have revealed that the scale is a tool that can measure academic staffs’ Self-Efficacy levels with five factors. The scale is expected to be used by researchers in the field.

Background: It is important that psychological structures have an impact on athlete performance, such as self-efficacy can be measured consistently. The aim of this study is to develop a measurement tool with psychometric properties that can measure the self-efficacy beliefs of athletes. Material and methods: The participants of the study consisted of 325 athletes (age 21.6 ± 4.2) who actively pursue sports in various sports branches in Turkey. In the validity and reliability analysis of the scale, exploratory and confirmatory factor analyzes were used. Cronbach’s Alpha reliability coefficient value of the total scale is .88. Results: The validity and reliability analysis results of the scale revealed that the scale was generally in perfect fit. As a result, it can be said that the Athlete Self Efficacy Scale (ASES) is a valid and reliable measurement tool and can be used to determine the self-efficacy levels of adult athletes. Conclusions: Validity and reliability studies of the Athlete Self Efficacy Scale should be repeated specific to the sport branch or in younger age groups. In addition, athlete's self-efficacy is a universal concept. In this respect, it is valid in other cultures and it is recommended to adapt the scale to other languages and cultures.

This study assessed the validity and reliability of the Placement Quality Survey (PQS) for measuring rural student clinical placement quality among allied health students attending rural placements. Secondly, the association of the PQS with students’ choice of rural placements and rural self-efficacy was determined. Students attending 5–8-week placements completed a paper-based questionnaire and were also invited to complete it again later the same day for reliability testing. Reliability and validity were tested. Analysis of variance was used to investigate relationships between PQS items and composite scores with student discipline, venue of student placement, and rural self-efficacy. Occupational therapy, physiotherapy and speech pathology students (N = 163) participated. From the exploratory factor analysis a single factor was extracted which accounted for 62.1% of the variance. The standard one factor confirmatory factor analysis demonstrated reasonable fit but with the addition of a covariance term provided a good fit. Increased preference for rural placements was demonstrated for eight out of nine nine-item PQS items. Rural self-efficacy increased quality ratings, supporting construct validity. The Cronbach’s alpha indicated a high level of internal consistency. All item-to-item correlations indicated a high level of consistency. Test-retest Pearson’s correlations and intraclass correlation coefficients of repeatability indicated the reliability of the scale over time. This study validated the PQS in a sample of rural allied-health students. The results provided support for reliability. The study addresses the critical need for placement quality data to improve allied health students’ experiences and learning outcomes on placements and encourage systematic quality improvement processes.

This study evaluated the psychometric properties of a self-report scale for assessing perceived driver competence, labeled the Self-Efficacy Scale for Driver Competence (SSDC), using item response theory analyses. Two samples of Swedish driving-license examinees (n = 795; n = 714) completed two versions of the SSDC that were parallel in content. Prior work, using classical test theory analyses, has provided support for the validity and reliability of scores from the SSDC. This study investigated the measurement precision, item hierarchy, and differential functioning for males and females of the items in the SSDC as well as how the rating scale functions. The results confirmed the previous findings; that the SSDC demonstrates sound psychometric properties. In addition, the findings showed that measurement precision could be increased by adding items that tap higher self-efficacy levels. Moreover, the rating scale can be improved by reducing the number of categories or by providing each category with a label.
