Sensitivity, Internal Consistency and Factorial Structure of the Arabic Version of OMSAT-3

Abstract

The aim of this study was to assess the sensitivity, internal consistency and the factorial structure of an Arabic version of OMSAT-3 among Tunisian athletes. A translated version of OMSAT-3 was administrated to a total of 526 Tunisian athletes from both sexes divided on elite (n = 240) and non-elite (n = 286) and aged between 16 and 19 years. The results showed robust psychometric properties for the Arabic version of the instrument: it was sensitive according to the level of practice (8/12 subscales could discriminate the elites and non-elites athletes). Cronbach's alpha revealed a good internal consistency (α > 0.70 for all the subscales). Also, confirmatory factor analysis provides a good adjustment index and adequate factorial structure. This version in Arabic language presents acceptable psychometric proprieties to evaluate the mental skills of the athletes in Tunisia and in other Arabic countries.

“…Finally, since the mental skills in sports are always linked to the social and cultural environment ( Guelmemi et al, 2015 ; Eubank et al, 2017 ; Gill et al, 2017 ) it would be beneficial to exam the effect of VE in various cultures and contexts.…”

“…However, the relationship between coaches and athletes, as well as teachers and students, significantly influences the effectiveness of verbal encouragement (VE).

Adult Vaccine Hesitancy Scale in Arabic and French: Protocol for Translation and Validation in the World Health Organization Eastern Mediterranean Region

“…Generally, there is a lack of consensus on the sample size required for validity testing of a scale [ 15 ]. A review of the research in this area found it has been recommended to use at least 10 participants per item when doing a comprehensive psychometric analysis [ 12 , 16 ] and that between 300 and 500 participants are required to perform an exploratory factor analysis (EFA) [ 12 ], which will be conducted in this study. A sample size of 1000 participants was deemed “excellent” for scale validation [ 12 , 17 ]; therefore, our proposed sample size is 1000 Arabic speakers and 1000 French speakers.…”

Mentální dovednosti českých sportovců: validační studie české verze dotazníku OMSAT-3*

“…Dotazník původně vznikl v angličtině, dále byl přeložen do rumunštiny (Craicun, 2009;Craicun, Dobosi & Rusu, 2009), portugalštiny (Vianna & Newton, 2005), francouzštiny (Fournier, Bernier, & Durand-Bush, 2006) či arabštiny (Noômen, Mohamed, Nasri, & Brahim, 2015). Ve všech překladech byla potvrzena jak vysoká reliabilita metody, tak faktorová struktura, což podtrhuje kvalitu tohoto nástroje.…”
