Impulsiveness is a personality trait that reflects an urge to act spontaneously, without thinking or planning ahead for the consequences of your actions. High impulsiveness is characteristic of a variety of problematic behaviors including attention deficit disorder, hyperactivity, excessive gambling, risk-taking, drug use, and alcoholism. Researchers studying attention and self-control often assess impulsiveness using personality questionnaires, notably the common Barratt Impulsiveness Scale version 11 (BIS-11; last revised in 1995). Advances in techniques for producing personality questionnaires over the last 20 years prompted us to revise and improve the BIS-11. We sought to make the revised scale shorter – so that it would be quicker to administer – and better matched to current behaviors. We analyzed responses from 1549 adults who took the BIS-11 questionnaire. Using a statistical technique called factor analysis, we eliminated 17 questions that did a poor job of measuring the three major types of impulsiveness identified by the scale: inattention, spontaneous action, and lack of planning. We constructed our ABbreviated Impulsiveness Scale (ABIS) using the remaining 13 questions. We showed that the ABIS performed well when administered to additional groups of 657 and 285 adults. Finally, we showed expected relationships between the ABIS and other personality measurements related to impulsiveness, and showed that the ABIS can help predict alcohol consumption. We present the ABIS as a useful and efficient tool for researchers interested in measuring impulsive personality.
Objectives: This study highlights demographics and orthopaedic injuries of electric scooter–related trauma that presented to our institution over a 27-month period. Design: Retrospective review. Setting: Urban Level 1 trauma center. Patients: Patients presenting to the emergency department, trauma bay, or outpatient clinic after electric scooter injury were identified from November 2017 through January 2020 using ICD-10 diagnosis codes. Main Outcomes: Patient charts were reviewed for demographics, injury characteristics, imaging, treatment, perioperative data, and Injury Severity Scores. Results: Four hundred eighty-five patients presented during the study period. Of these, 44% had orthopaedic injuries, including 30% with pelvis or extremity fractures. There were 21 (10%) polytraumatized patients in the orthopaedic cohort. The age ranged from 16 to 79 years (average 36 years), with 58% men, and 18% were visitors from out of town. Of 49 patients requiring orthopaedic surgery, 8 underwent surgery on an urgent basis. The average Injury Severity Score for orthopaedic patients was 8.4 with a median of 5.0 for nonoperative injuries versus a significantly higher median of 16.0 for operative injuries. Twenty-nine percent of patients were intoxicated and only 2% wore a helmet. Conclusions: Electric scooter injuries are increasing, and many patients sustain high-energy injuries. As electric scooter use continues to increase, the prevalence of orthopaedic injuries is also likely to rise. Further studies are needed to fully understand the impact scooter-related injuries have on individual patients and the health care system. Level of Evidence: Prognostic Level IV.
