RT Journal Article SR Electronic T1 Measuring injury risk factors: question reliability in a statewide sample JF Injury Prevention JO Inj Prev FD BMJ Publishing Group Ltd SP 148 OP 150 DO 10.1136/ip.6.2.148 VO 6 IS 2 A1 Jane Koziol-McLain A1 David Brand A1 Daniel Morgan A1 Marilyn Leff A1 Steven R Lowenstein YR 2000 UL http://injuryprevention.bmj.com/content/6/2/148.abstract AB Background—Recently (1996–98), Colorado added 15 questions pertaining to injury related risks and behaviors to the behavioral risk factor surveillance system (BRFSS). Questions addressed bicycle helmet use, traffic crashes, exposure to violence, suicidal behavior, and gun storage. Objective—To measure the test-retest reliability of these injury related questions. Methods—Of 330 BRFSS participants, 229 (69%) were called a second time and reasked nine selected injury questions. Retests were completed 7–28 days after the original interview. Results—Test-retest agreement was very high (κ >0.80) for bicycle helmet use, domestic police visits, and gun ownership. All other injury risk questions had substantial agreement (κ >0.60). Conclusions—The injury related questions added to the Colorado BRFSS have high test-retest reliability.
