| Abstract: | Objective: Brief Self-Control Scale (BSCS) is the most widely used instrument to assess self-control. The purpose of this reliability generalization meta-analysis was to examine the degree to which consistency reliability coefficients for scores on the BSCS generalize across age groups and languages.Method: We included studies using the BSCS and reporting a Cronbach's alpha coefficient score since January 2018.Results: Our analysis (j = 180; k = 211) yielded an overall Cronbach's alpha value of.81 for the unidimensional 13-item BSCS. Moderator analysis showed that reliability scores ranged from.71 to.81 across age groups and from.77 to.90 across languages.Conclusions: Though all internal consistency scores fell in either a good or acceptable range, researchers can consider using a child-specific instrument to assess self-control among children. Reliability scores were also higher in Western areas (e.g., North America) than in non-Western countries. This study evaluated the score reliability of the 13-item unidimensional BSCS, an instrument measuring self-control. Overall, the BSCS showed good reliability scores. However, reliability scores varied across languages and age groups. [ABSTRACT FROM AUTHOR] |
