The aim of the present study was to examine the construct validity of the Self-Efficacy Scale for Driver Competence (SSDC). The SSDC was based on a theoretical model for perceived driver competence, based on the self-efficacy construct and five aspects of driver competence. Two samples of driving license examinees (n = 805, n = 721) completed two parallel versions of the SSDC. Participants’ mean age was 21.5 years and of them 44% were women. Both versions of the SSDC had sound psychometric properties. The results provided support for substantial and structural aspects of construct validity. Some evidence of external validity of the test scores was obtained, although the relationship between perceived and actual driver competence was weaker than expected. The consequences of the use and interpretation of SSDC are discussed.

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.

Background & Aim: Self-care in patients with heart failure can improve multiple outcomes and reduce mortality. Measuring self-care requires valid and reliable tools. This study aimed to determine the psychometric properties of the 9-items European Heart Failure Self-Care Behavior Scale. Methods & Materials: The present study is a psychometric evaluation. The original version of the tool was translated from English to Persian using the standard Backward-Forward method. The questionnaire's validity was assessed using face, content, criterion (the Self-Care of Heart Failure Index v.6 as a criterion), and construct validity.  An exploratory factor analysis approach was used to construct validity with a sample of 216 patients with chronic heart failure referred to Dr. Shariati and Imam Khomeini Hospital's heart clinics in Tehran; and Ayatollah Mousavi Hospital in Zanjan. The reliability of the questionnaire was evaluated by internal consistency and stability methods. Results: After the validation process (validity and reliability), all 9 items of the questionnaire were approved and remained. The content validity index of the total content of the questionnaire was calculated to be 0.96. Based on factor analysis, only one factor was confirmed for the questionnaire. The correlation between the present questionnaire and the Self-Care of Heart Failure Index v.6 was positive and significant (p<0.001, r=0.753). Internal consistency (α=0.728) and stability (0.897) of the questionnaire were also confirmed. Conclusion: The European Heart Failure Self-Care Behavior Scale is valid and reliable for measuring Iranian patients' self-care behaviors with heart failure.

This research was conducted for analyzing the effect of mediating variable that is individual task proactivity as one of the proactivities of behavior towards the relationship between self-efficacy and the employees’ performance in the logistics companies of shipping the goods. It uses convenience sampling, which is a non-probability sampling method for getting the sample of 52 employees. They were divided into two divisions, namely infrastructure and quality assurance. The questionnaire consists of two parts, in which some were assessed by themselves and others that were assessed by the supervisor. They were analyzed using path analysis using analytical tools developed by Hayes, Preacher-Hayes with the simple mediation models. It was found that employees have self-efficacy, individual task proactivity, and relatively high performance, in which individual task proactivity can be a mediating variable on the effect self-efficacy on performance.

The present study examined the moderating effect of supervisory support on the relationship between self-ratings of self-efficacy and two measures of work performance, namely supervisor-rated performance and a work-output measure. Research was conducted within the South African life insurance industry on a sample of broker consultants (sales promotional staff) ( n = 70 subjects) over a three-month period. Past research found a positive relationship between high self-efficacy and work performance. However, such research did not take account of the influence of leadership factors. It was hypothesised that effective supervisory support would facilitate the attainment of higher levels of performance. Therefore, it was hypothesised that supervisory support should moderate the self-efficacy work performance relationship, particularly in the case of low self-efficacy. As hypothesised, it was found that supervisory support moderated the relationship between self-efficacy and supervisor-rated performance. Performance was highest when low levels of self-efficacy occurred together with high supervisory support. However, supervisory support did not moderate the relationship between self-efficacy and the work-output measure of performance. Limitations of the study, as well as theoretical and practical implications are considered.

The lack of self-directed learning of students shown by students is one problem associated with self-efficacy and the learning environment. The purpose of the research is to reveal the relationship between self-efficacy and the learning environment, and self-directed learning. This study uses the correlational method and data collected from a sample of 198 students, which were found using proportional random sampling techniques. Data were collected using a self efficacy scale (24 valid items = 0.851), a learning environment scale (32 valid items = 0.830), and a self-directed learning scale (64 valid items = 0.936). Data were then analyzed using multiple regression. The results showed the correlation coefficient r = 0.535 and p = 0.00 (p> 0.05), which showed that there was a positive and significant relationship between self-efficacy and the learning environment together with self-directed learning. So it can be explained that the higher the self-efficacy and learning environment, the higher the student's self-directed learning.

Today, cybersecurity is a growing issue in our education society to ensure a safe teaching and learning process for teachers and students. Reports and studies demonstrated that teachers and students are moderately aware of the cybersecurity threat surrounding them that could affect the learning curve and other fatal impacts. This study aims to identify the role of self-efficacy in the relationship between knowledge, attitude, and environment behavior of cybersecurity awareness. The researchers used a correlational design with a quantitative approach by using a questionnaire instrument to collect data from teacher respondents. A total of 350 teachers in took part in this survey voluntarily, distributed using social media applications in the midst of the Covid-19 pandemic. The researchers used the IBM SPSS Statistics to analyze the data descriptively and inferentially. The levels of knowledge, attitude, self-efficacy, and environment behavior of Malaysian school teachers towards cybersecurity awareness are low. Self-efficacy acts as a moderator in influencing the relationship between knowledge, attitude, and environment behavior of cybersecurity awareness. Strategies and programs need to be initiated by stakeholders to increase the self-efficacy of cybersecurity that could assist the positive change of environment behavior among teachers for teaching and learning benefit.

The study looked at factors that influenced the self-efficacy in teaching English as a Foreign Language (EFL) of a group of university teachers in Vietnam. This study explored the relationship between Vietnamese teachers’ discourses of effective teaching practices and their self-efficacy beliefs, the influence of Vietnamese culture and context on teachers’ self-efficacy beliefs, and whether participating in the research led to a change in the self-efficacy beliefs of the teacher participants and of myself as researcher.The research took the form of a qualitative case study. Participants were eight university teachers of the English language at a technical university in Vietnam. Data collection lasted six months. Data collection tools included focus group discussions, individual interviews, journaling, and observations. An inductive coding process and thematic analysis were used for analysing data. Findings indicate that social persuasion was the most influential source of self-efficacy information. The study shows that different sources of self-efficacy information interacted with one another to influence the two dimensions of self-efficacy. Besides, it appears that teachers’ understanding of a number of environment and workplace factors appeared to constrain some teachers into adopting the Grammar Translation Method (GTM) approach and possibly reduced their self-efficacy in adapting a Communicative Language Teaching (CLT)-oriented approach. After participating in the study, the teaching approaches of study teachers and my own approaches seemed to be more CLT-oriented although most of us were characterised by a low sense of self-efficacy in adapting this approach in the Vietnamese classrooms. Findings also suggest that several aspects of Vietnamese culture, e.g. the concept of face, are likely to have influenced the way the study teachers selected, weighted and interpreted efficacy-building information. In addition, it is plausible that changes in context, e.g. teaching different kinds of students, led to a change in the way the teachers and I weighed and selected self-efficacy information. Self-reflection, self-doubt and self-regulation were other factors causing fluctuations in the study teachers’ and my self-efficacy. My study contributes to a widening understanding of how different aspects of culture can impact on self-efficacy. It provides examples to challenge the claim that the self-efficacy of experienced teachers is stable and the widespread view that a negative sense of self-efficacy induces individuals to give up and make less effort. The study shows the relationship between teacher self-efficacy beliefs and their discourses of EFL instruction, i.e. their self-efficacy in using different aspects of a communicative approach fluctuated at different stages of the study. The study points to the need to improve leadership practice and teaching conditions at the faculty and university. Preparing teachers for regulation strategies, encouraging them to work collectively, and offering more professional development programs are likely to develop a stronger sense of self-efficacy among teachers.
