Major depressive disorder is the most common psychiatric illness in Iran, and depression is common among university students in the country. The presence of depression is frequently associated with problems in executive functioning. The Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A) is a questionnaire measure designed to assess executive functioning in everyday life in clinical and non-clinical populations. Currently, there is limited empirical validation of the measure for use in Iran. This study evaluated the psychometric properties of a Persian-language BRIEF-A in a sample of Iranian university students (n = 300). The factor structure of the BRIEF-A was examined via a confirmatory factor analysis. We also evaluated whether BRIEF-A scores differed among university students varying in severity of depressive symptoms (Minimal, Mild, Moderate, Severe) as measured by the Beck Depression Inventory – II. Results indicated that a two-factor model structure best fit the data for the BRIEF-A. Acceptable internal consistency was also observed. Furthermore, poorer subjective executive functioning was endorsed by the three depressive subgroups relative to the Minimal symptoms group. Together, these findings support a two-factor model for the Persian translation of the BRIEF-A, and indicate that more severe depressive symptoms in Iranian university students is associated with worse subjective executive functioning.

The Barkley Deficits in Executive Functioning Scale–Children and Adolescents (BDEFS-CA) is an empirically based tool for evaluating clinically significant dimensions of child and adolescent executive functioning. The present study examined the psychometric properties of Persian version of the BDEFS-CA Long Form parent-report in children and adolescents aged 6–18 years old (n = 2,295, 51% girls). The results of confirmatory factor analysis (CFA) consistently underscored a five-factor structure (self-management to time, self-organization/problem solving, self-restraint, self-motivation and self-regulation of emotion), resembling the original factor structure, in Persian language. Additionally, Results showed that Persian version of the BDEFS-CA Long Form demonstrated high internal consistency and test–retest reliabilities. Convergent validity with Childhood Executive Functioning Inventory (CHEXI) and divergent validity between normal and clinical groups were good. Overall, findings provide support for the validity and reliability Persian version of the BDEFS-CA Long Form, which can be used to assess executive dysfunction in daily life activities.

This study investigated the association of sluggish cognitive tempo (SCT), processing speed, and executive function (EF) in children with specific learning disabilities (SLD), and the typically developing children (TD) (60 female students aged between 8 and 10). Child and Adolescent Behavior Inventory-Parent Version (CABI), the Barkley Deficits in Executive Functioning Scale-Children and Adolescents (BDEFS-CA), and Wechsler Intelligence Scale for Children-IV (the Processing Speed Index (PSI) were used to assess SCT, processing speed, and EF. The results showed that SCT problems were higher in children with SLD (p < 0.001). In addition, results showed that children with SLD had poorer performance on processing speed (p < 0.001) compared to the TD group. Executive dysfunctioning in self-management to time, self-organization, problem-solving, self-restraint, self-motivation, and self-regulation of emotions were poorer in children with SLD than TD group (p < 0.05). This study provides initial evidence that SCT symptoms are poor in female children with SLD, and associated with executive dysfunction and poor processing speed.
