Self-efficacy in volleyball: What has been evaluated? A systematic review

Abstract

Self-efficacy in sport has been the purpose of study in different modalities, among them the volleyball. The aim of the study was to verify by means of a systematic review what has been evaluated volleyball self-efficacy. The databases APA, Bireme, Eric, Science Direct, Pubmed and Scopus were used to carry out the searches. After the research, the articles were selected, using the inclusion and exclusion criteria, resulting in 7 articles by the theme. The result points a absence of clarity in the instruments for assessing self-efficacy in volleyball with respect to what they intend to measure in relation to technical, tactical, physical or psychological attributes. In addition, few articles have pointed the psychometric properties of the instruments used in the research, which implies, in practical terms, inaccurate results, hindering the reproducibility of the studies. Therefore, it is suggested that specific instruments for the modality should be developed which present the statistical procedures used in order to obtain reliable results.

The Effect of Self-Efficacy on Teachers' Organizational Citizenship Behavior: A Case of MTsN 1 Mataram City

“…This is in line with research conducted by Massaty et al, (2020) which states that teacher self-efficacy on this indicator can be seen by having strong selfconfidence towards self-potential in completing tasks. Machado et al, (2019) stated that the strength of teacher self-efficacy reflects how confident a person is in his or her ability to perform a given task. The teacher's belief in this indicator is closely related to the determination that he will succeed in dealing with a problem (Xie et al, 2020).…”

Examining the antecedents of medical tourists' use of social media from the standpoint of self-efficacy

“…The term "self-efficacy" is used to describe a person's confidence in his or her own abilities to complete a certain task (Meissel and Rubie-Davies, 2016) and is core concept and key factor in social cognitive theory (Schunk and DiBenedetto, 2020). Efficacy beliefs, which are JHTI 7,2 considered as predictors of performance, are the result of a complex process of selfpersuasion (Machado et al, 2019). Individuals' belief systems are linked to how they evaluate emerging technologies and how they embrace them (Ali et al, 2018).…”

Development and Validation of the High Performance Volleyball Self-Efficacy Scale

“…The use of the CR coefficient is justified by the fact that this is a more robust equation than Cronbach's alpha since it is sensitive to the factorial load of each item in its factor, as well as to the number of items used in each scale (Valentini & Damásio, 2016). A systematic review by Machado et al (2019) on measurement instruments used to assess self-efficacy with volleyball athletes found only results for Cronbach's alpha in these instruments (Blecharz et al, 2014;Guicciardi et al, 2016;Zetou et al, 2012), making it infeasible to compare the results obtained in this study.…”

“…Past research on sport and exercise psychology (Zhu, 1998(Zhu, , 2012, particularly research studies on self-efficacy in volleyball (Machado et al, 2019), have documented a reliance on outdated validation practices and language content of assessment tools, minimal reference to the validity of obtained scores, or incorrectly labeled validity evidence, and/or neglect of validity theory in validation research (Blecharz et al, 2014;Costa et al, 2012;Gomes et al, 2012;Guicciardi et al, 2016;Lox, 1992;Vargas-Tonsing et al, 2003;Zetou et al, 2008Zetou et al, , 2012. Grunnell et al (2014) called for improvements in the measurement instruments used in this discipline.…”

“…In the volleyball context, athletes are constantly in tense situations, as errors can be decisive for the set or match. Effective actions in various fundamental skills that make up the game require athletes to have optimal psychological characteristics for good performance (Machado et al, 2018), meaning that their self-efficacy must be adequately assessed (Machado et al, 2019).…”
