Verbal fluency in Lebanese children: Preliminary normative data, sociodemographic determinants, and patterns of clustering and switching.

This study assessed the quantitative and qualitative performance of Lebanese-speaking children on verbal fluency (VF) tasks and investigated the effects of sociodemographic characteristics. This study included 219 Lebanese children aged between 5 and 12 years and 11 months, whose native language is Lebanese-Arabic. Semantic and letter VF tasks were assessed using a range of categories and letters. Switching and clustering strategies were analyzed for 177 Lebanese children. The number of words produced presented a significant increase with age (p < .004) in semantic (SVF), while in letter (LVF), the differences were significant between extreme age groups. Females generated more words in the clothes (p = .003) and household items (p = .002) categories. The total number of switches and clusters showed a significantly increasing pattern with age (p < .05). The number of switches was higher for participants with high maternal (p < .001) and paternal (p < .013) educational levels. Regression analyses showed that the total number of switches and clusters, and the mean cluster size had a significant effect on SVF performance (p < .001). The current study generated preliminary norms for VF tasks for Lebanese-speaking children. The results of the current study have an important contribution to neuropsychology research and clinical practice.
