This research group received funding from the following research projects: PY20-RE-022 UGR, PDC2021- 12944-I00, PID2020-113978RB-IOO) MCIN/AEI/10.13039/ 50110001103, supported by the State Research Agency (SRA) and Eu- ropean Regional Fund (ERDF). We express our gratitude to these in- stitutions for their support. The study’s design, data collection, analysis and interpretation were conducted independently of the funding bodies, as was the writing up of the experiment and the decision to seek publication”. Research on motorcycle rider distraction and inattention is limited, especially when compared to that on car drivers. This study examines motorcycle rider error and its relationship with engagement in distracting activities. Additionally, it provides an adaptation of the Attention-Related Driving Errors Scale for use with motorcycle riders (ARDES-M). A sample of 418 motorcyclists responded to a web questionnaire consisting of the ARDES-M, a self-report measure of Involvement in Distracting Activities (IDA), a measure of everyday inattention (ARCES, Attention Related Cognitive Errors Scale) and socio-demographic and riding-related questions. Riding errors were associated with a higher level of engagement in distracting activities and a greater propensity for inat- tention in daily life. ARDES-M scores were associated with various types of self-reported traffic crashes and near- crashes, while self-reported distractions (IDA) were only linked with near-crashes. The most widely self-reported distracting activities were using map navigation, listening to the radio or to music and adjusting vehicle devices. The various uses of cell phones were relatively minor. Young riders reported higher levels of engagement in distracting activities and committing more riding errors. The ARDES-M showed good psychometric properties for the sample in Spain. 2023-04-17T11:22:49Z 2023-04-17T11:22:49Z 2023-04-17 journal article Ledesma, R.D., Padilla, J.L.
