Validity and reliability evidence of general self-efficacy scale in Greek adults with asthma

Empowering employees becomes a current issue as leadership approach as well as a managerial means of contemporary approaches. Empowering employees is predicted to impact on self- efficacy positively. In the first phase of the study, the investigation of validity and reliability of empowering leadership and self-efficacy scale were conducted among healthcare employees in Turkey. In the second phase, the relationships between empowering leadership and the sub- dimension of empowering leadership and self-efficacy were searched. The related scales were performed among 550 healthcare employees, who were selected randomly from 7 different hospitals of states that in different regions of Turkey. Empowering leadership scale of Amundsen and Martinsen (2014), and General Self-efficacy scale of Chen, Gully and Eden (2001) were used to measure designed model within the study. As the results of the study, a new version of empowering leadership scale, which is consisted of 2 dimensions and 5 questions in each dimensions and has reliability and validity in Turkish, was reached. Moreover, a new self- efficacy scale that is insisted of one dimension and 4 questions and has reliability and validity in Turkish was obtained within the analyses. Empowering leadership as total score, sub-dimension of empowering leadership as autonomy and development supportaffects on self-efficacy positively.

General Self Efficacy

Abstract. General self-efficacy is a central personality trait often evaluated in surveys as context variable. It can be interpreted as a personal coping resource reflecting individual belief in one’s overall competence to perform across a variety of situations. The German-language Allgemeine-Selbstwirksamkeit-Kurzskala (ASKU) is a reliable and valid instrument to assess this disposition in the German-speaking countries based on a three-item equation. This study develops a French version of the ASKU and tests this French version for measurement invariance compared to the original ASKU. A reliable and valid French instrument would make it easy to collect data in the French-speaking countries and allow comparisons between the French and German results. Data were collected on a sample of 1,716 adolescents. Confirmatory factor analysis resulted in a good fit for a single-factor model of the data (in total, French, and German version). Additionally, construct validity was assessed by elucidating intercorrelations between the ASKU and different factors that should theoretically be related to ASKU. Furthermore, we confirmed configural and metric as well as scalar invariance between the different language versions, meaning that all forms of statistical comparison between the developed French version and the original German version are allowed.

Two Samples

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.
