Executive Functions and Sluggish Cognitive Tempo in People with Depressive Disorder and Normal

Depression is a mood disorder that results in persistent feelings of sadness and loss of interest. The purpose of this study was to compare the executive functions and sluggish cognitive tempo of individuals with depressive disorder to those who are normal. The present study utilized a descriptive causal-comparative method. The statistical population consisted of clients with depression disorder who visited Health Centers in Tabriz city. A total of 100 participants were selected to take part in the research. The executive skills questionnaire (Strait et al., 2019), Sluggish Cognitive Tempo questionnaire (Beker et al., 2017), and the depression screening questionnaire (PHQ-9) were used to collect data. The results of the multivariate analysis of variance indicated that individuals with depression exhibited weaker performance in all components of executive functions (planning, time management, emotion regulation, organization, and behavior regulation) compared to the healthy group (p < 0.001). Additionally, the Sluggish Cognitive Tempo component was significantly higher in depressed individuals than in normal individuals (p < 0.001). Therefore, based on the findings of this study, it can be concluded that individuals with depression experience serious deficiencies in executive functions and encounter more problems in the Sluggish Cognitive Tempo component than the healthy group.
