Structural relationships of the Adult Attention-Deficit/Hyperactivity symptoms, Sluggish Cognitive Tempo, and driving behavior: mediating role of procrastination.

This study aims to investigate the structural relationships among adult Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms, Sluggish Cognitive Tempo (SCT), and driving behavior with the mediation of procrastination. This study employed a descriptive-correlational design and recruited a convenience sample of 250 licensed drivers in Tabriz, Iran. The data were collected using four instruments, namely, Adult ADHD Self-Report Scale (ASRS), Adult Concentration Inventory (ACI), Tuckman Procrastination Scale (TPS), and Manchester Driving Behavior Questionnaire (MBDQ). Correlation and structural equation modeling techniques which were performed by SPSS 20 and AMOS 24 software, were used to analyze the data. The study conducted a statistical analysis that revealed several significant relationships. Firstly, there was a significant association between ADHD symptoms ( β = 0.25 , p < 0.05 ) and SCT symptoms (β = 0.18 , p < 0.05) with driving behavior. Secondly, the study found a significant correlation between ADHD (β = 0.52 , p < 0.05) and SCT symptoms (β = 0.33 , p < 0.05) with procrastination. Procrastination was also significantly related to driving behavior (β = 0.37 , p < 0.05) . Moreover, the study identified that ADHD (β = 0.19 , p < 0.05) and SCT symptoms (β = 0.12 , p < 0.05) had a significant effect on driving behavior, with procrastination serving as a mediator. Based on the results, this study has identified additional SCT dimensions associated with adult hyperactivity and procrastination, which contribute to the current understanding of the topic.
