Divided attention assessment: cross-cultural adaptation and psychometric properties of the Persian version of the Divided Attention Questionnaire (P-DAQ) among male older drivers.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundWith the rise in older drivers and in-vehicle technologies that may cause cognitive distractions, assessing cognitive abilities like divided attention is essential. Therefore, this study aimed to examine the psychometric properties and cross-cultural adaptation of the Persian version of the Divided Attention Questionnaire (P-DAQ) among male older drivers. Methods: This methodological study employed convenience sampling for participant selection, with data collected from older adults via face-to-face interviews in Khorramabad, Iran. The P-DAQ was translated, culturally adapted, and its psychometric properties were analyzed using SPSS v.22, with statistical significance set at p < 0.05.
resultsA total of 200 participants were included in the study. The mean (SD) score for the P-DAQ, Attentional Control Scale (ACS) and Adelaide driving self-efficacy scale (ADSES) were 38.06 (16.10), 42.39 (8.57) and 95.08 (12.3), respectively. Experts confirmed face, content, and cross-cultural validity. Confirmatory factor analysis showed a good model fit (GFI = 0.92). The questionnaire’s convergent validity was assessed by examining its Pearson correlation with the ACS (r = -0.72, p < 0.05) and ADSES (r = -0.48, p < 0.05). Internal consistency (Cronbach’s α = 0.86) and test-retest reliability (ICC = 0.99) were high. Divided attention scores varied significantly by demographic factors including age, kidney disease, drug abuse, a history of car accidents, education levels, perceived economic status, and the number of medications used (p < 0.05).
conclusionThe P-DAQ demonstrated high validity and reliability, making it a valuable tool for assessing divided attention among male older drivers.
