Reliability Generalisation Meta-Analysis Of The Communicatıon Skills Assessment Scale

Communication skills, which play a central role in interpersonal communication processes, are one of the fundamental areas of study that have been addressed in the literature for a long time and continue to attract the interest of researchers. In this regard, numerous measurement tools have been developed to explain and measure the different dimensions of communication skills; comprehensive studies have been conducted to resolve uncertainties regarding the theoretical and practical aspects of the concept through these tools. Among these measurement tools, the Communication Skills Assessment Scale (CSAS), developed by Korkut (1996) and widely used in the national literature, is noteworthy. This study aims to conduct a meta-analysis of reliability generalisation to systematically examine the reliability of the Communication Skills Assessment Scale, which is frequently used in different samples and research conditions. Within this scope, a total of 88 studies (N = 29,454) that used the CSAS and reported Cronbach's alpha reliability coefficients were included in the meta-analysis. The random effects model was used to combine the Cronbach's alpha coefficients. The aforementioned value was transformed using Bonett's method. The study included reliability generalisation and analyses of heterogeneity, publication bias, forest plots, Analog ANOVA, and meta-regression. Analog ANOVA was applied for categorical variables and meta-regression analyses for continuous variables to explain the variation in reliability coefficients. The study found that the average effect size was 0.895 (95% CI: 0.881–0.908). However, moderator analyses conducted on different variables did not yield any significant results. The findings revealed that the CSAS is a measurement tool that produces consistent and highly reliable scores in different samples and study conditions.
