The impact of neuroticism on an individual's intelligence scores: a cross cultural study

Intelligence scales have become a commonly used method for the prediction of human performance across a variety of occupations and settings. Nevertheless, there is still debate among researchers about whether the results of these scales can be considered an accurate indicator of an individual's true capability or whether they also reflect the impact of personality traits on intelligence scores. Researchers have begun to investigate connections between neuroticism and intelligence scores, but the results of studies are somewhat conflicting and inconclusive. Moreover, it is noteworthy that few studies have considered cross-cultural differences in this relationship, and have systematically examined age and sex differences when explaining the relationship between intelligence scores and neuroticism. To replicate and extend previous work, four independent but related studies were conducted to explore the empirical relationship between neuroticism and intelligence scores, and the mediation effect of sex, age and cultural differences in this association. Study 1 investigated the psychometric properties of an English version of the Neurotic Behaviour Scale (NBS) among a student population of undergraduate students (N = 177). The NBS is a specifically-designed test by the author to measure the neuroticism trait among the Libyan population. The results confirmed the validity and reliability of using the English version of the NBS for the remaining studies in the thesis.
