A questionnaire was developed based on relevant literature and fine-tuned by a panel of experts. The questionnaire was administered to a sample of 1212 heterosexual Muslim individuals of 389 married couples aged 22–55 years old (overall mean age = 38.15 years, SD = 9.47; husbands’ mean age = 38.25 years, SD = 9.23; wives’ mean age = 38.06, SD = 9.70). The participants were divided into two subsamples for exploratory and confirmatory factor analysis and to draw Pearson correlations with the Dyadic Adjustment Scale (DAS) for validation procedures. The results indicate the strong statistical significance of a 22-item five-factor structure: structural attribute satisfaction, marital harmony, emotional and sexual harmony, spouse’s family communication, and religious matters. The factors were interpr...

Research paper thumbnail of Effect of ADHD traits in young drivers on self-reported deviant driving behaviours: An exploratory study in the Arab gulf region

Methods In this exploratory study, a sample of 450 young drivers from the State of Qatar have been administered the Adult ADHD Self-Report Scale (ASRS-V1.1) and the Driver Behaviour Questionnaire (DBQ), in order to examine the impact of self-reported inattention and hyperactivity-impulsivity traits on self-reported intentional traffic violations, unintentional driving errors, concentration or memory lapses and deliberate aggressive violations. A path analysis model was developed to test the predictability of these ADHD traits on deviant driving behaviours. Results The positive relationships among both traits and deviant driving behaviours varies across gender. Young male drivers with hyperactivity-impulsivity traits are significantly more likely to report ordinary violations, errors, lapses and aggressive violations, but these aberrant driving behaviours are most likely to be reported by young female drivers who report the inattention trait. Nevertheless, the inattention trait has a minor predictive role for young male drivers and is not significantly related to aggressive violations. For young female drivers aggressive violations are not predicted by the hyperactivity-impulsivity trait, but the inattention traits among young female drivers is the strongest predictor of aggressive violations. Conclusion This exploratory study is important to create a better understanding of the increased risks among female drivers who predominantly exhibit the inattention trait and male drivers who predominantly exhibit the hyperactivity-impulsivity trait and could suggest gender-sensitive driving education about ADHD traits and driving risks.

Methods: A sample of 450 young drivers from the State of Qatar were asked to fill the Adult ADHD Self-Report Scale and the Driver Behaviour Questionnaire, in order to examine the impact of self-reported ADHD traits on ordinary violations, driving errors, lapses and aggressive violations. A path analysis model was developed to test the predictability of these ADHD traits on deviant driving behaviours. Results: Male drivers with hyperactivity-impulsivity traits are significantly more likely to report deviant driving behaviors. In contrast, female drivers with inattention traits are more likely to report deviant driving behaviors. The inattention trait has a minor predictive role for young male drivers and is not significantly related to aggressive violations.

In addition, the functioning of the four WM components was compared among dependents of various types of drugs.MethodIn total, 128 chronic drug dependents participated in this study. Their average age was 38.48 years, and they were classified into four drug‐dependence groups. Chronic drug dependents were compared with a 36‐participant control group that had a mean age of 37.6 years. A WM test battery that comprised eight tests and that assessed each of four WM components was administered to each participant.ResultsCompared with the control group, all four groups of drug dependents had significantly poorer test perfor...

However, the most common issue surrounding this test is the lack of accurate normative scores for use with non-white ethnic groups. The purpose of this study was to examine the BAFRT’s reliability and validity for use with Arab children, as well as to provide normative data for this group. Methods: The BAFRT was translated into Arabic and back-translated to ensure accuracy. The test was administered to a cohort of 394 Arab children, consisting of both cognitively normal children (n = 269) and children diagnosed with a psychological disorder (n = 125), all aged 5–8 years old. Test-retest reliability was assessed using a sub-set of children and validity was tested against clinical status as well as CBCL and SDQ measures. Normative measures were calculated after examining the impact of influencing variables such as age and gender. Result...

One aim of the current study was to examine the changes in WM during childhood. A second aim was to examine whether WM structure changes across age development from four to12 years old. A battery of WM tests-assessing the three basic WM components-was administered to a total sample of 891 Kuwaiti children (50.5% females and 49.5% males(aged 4 to 12 years. The data were analyzed by means of the CFA using Chi-squared values and four additional fit indices (i.e., Root Mean Square Error of Approximation RMSEA, Incremental Fit Index (IFI(, Non-Normed Fit Index (NNFI(, and the Comparative Fit Index (CFI(. Results presented evidence that the organizational structure of the three-factor WM construct exists across the four age bands, and the WM structures is fixed and invariant-in factor loadings, intercepts, and covariance-across age development from four to 12 years. These findings support the Baddeley and Hitch's tripartite model of WM during childhood.

Although drug-dependent individuals tend to take more risks than non-drug users, the factors underlying risk-taking are unknown. The current study tested, for the first time, the influences of performance feedback (i.e., whether feedback about performance is integrated into decision-making in heroin-dependent individuals) and attention to environmental contingencies (i.e., the influence of the probability o...

Thus, a review of factors associated with the holistic management of schizophrenia is of paramount importance. The objective of this review is to improve the quality of life of individuals with schizophrenia, by addressing the factors related to the needs of the patients and present them in a unified manner. Although medications play a role, other factors that lead to a successful holistic management of schizophrenia include addressing the following: financial management, independent community living, independent living skill, relationship, friendship, entertainment, regular exercise for weight gained due to medication administration, co-morbid health issues, and day-care programmes for independent living. This review discusses the relationship between different symptoms and problems individuals with ...

Exp. 1 investigated the role of executive control of working memory in situation awareness in a real-life driving simulation. Exp. 2 examined the extent to which taxing the central executive might affect situation awareness. High, Medium, and Low Situation Awareness groups were formed as assessed using the Situation Awareness Global Assessment Technique. Executive function was measured using several tests. Results from Exp. 1 demonstrated that the Low Situation Awareness group performed significantly worse on all executive function tasks compared to High and Medium Situation Awareness groups. Findings from Exp. 2 suggested that concurrent load on the central executive dramatically affected the Low Situation Awareness group but not the High Situation Awareness group: the former had significantly more driving violations under central executive load.

A sample of 662 Egyptians (54.83% females and 45.17% males) aged 26, 16 years was administered a comprehensive battery of 25 cognitive, psychopathological and psychosocial measures. The data were analyzed using Exploratory Factor Analysis and Structural Equation Modeling techniques to test the research hypothesis. The results revealed that the cognitive model, psychopathological model and psychosocial model did not fit the data well individually. However, an integrative model that included 22 psychopathological constructs, five cog-nitive constructs, and four psychosocial constructs fit the data very well. Both males and females conceptualized the constructs similarly, and there were no significant latent gender mean differences in any constructs involved in the research model, including radicalism. These findings imply that none of the models can solely explain radicalism, whereas the integrative model can. The findings support the notion that radicalism is a product of, but is not limited to, complicated trajectories of cognitive, psychopathological, and psychosocial factors.

Their average age was 38.48 years, and they were classified into four drug-dependence groups. Chronic drug dependents were compared with a 36-participant control group that had a mean age of 37.6 years. A WM test battery that comprised eight tests and that assessed each of four WM components was administered to each participant. Results: Compared with the control group, all four groups of drug dependents had significantly poorer test performance on all of the WM tasks. Among the four groups of drug users, the polydrug group had the poorest performance scores on each of the eight tasks, and the performance scores of the marijuana group were the least affected. Finally, the forward digit span task and the logical memory tasks were less sensitive than other tasks when differentiating between marijuana users and the normal participants. Conclusion: The four components of WM are impaired among chronic drug dependents. These results have implications for the development of tools, classification methods and therapeutic strategies for drug dependents.
