Abstract：
Objective This study aimed to describe the methodological process for developing a questionnaire to identify the prevalence and risk factors for chronic occupational low back pain in healthcare professionals working at hospitals. Method An exploratory crossectional survey study was carried out in Belo Horizonte, MG, Brazil, and its metropolitan region, in two stages. Initially, the authors prepared a questionnaire based on the Roland Morris disability questionnaire and sent it to a committee of low back pain specialists for validation using the Delphi technique. The second stage consisted of sending the final questionnaire to health professionals working in a hospital environment for at least 2 years and presenting chronic low back pain for at least 3 months. Results Validation occurred in two rounds of questionnaire adjustments by a panel consisting of physical therapists and physician experts in the field (orthopedists with more than 3 years of experience). Both rounds had 13 participants. The questionnaire initially consisted of 27 items, and, after validation, it had 19 items. The study included 65 subjects, with an average age of 40.91 years old and an average time working at a hospital of 40 hours per week. The total sample had 76.9% of physicians, 10.8% of physical therapists, and 12.3% of nurses or nursing technicians. Most (52.3%) subjects reported staying in uncomfortable positions affecting the lower back for 5 to 10 hours per day. Conclusion We developed and validated, using the Delphi technique, a questionnaire on the prevalence and risk factors associated with chronic occupational low back pain among healthcare professionals working at hospitals. This unprecedented tool can benefit the population studied since the questionnaires currently used to evaluate chronic low back pain are not specific for investigating the occupational cause of this condition.
摘要：
目的本研究旨在描述开发问卷的方法过程，以确定在医院工作的医疗保健专业人员中慢性职业性下腰痛的患病率和危险因素。方法在贝洛奥里藏特进行探索性横断面调查研究，MG,巴西,和它的大都市地区，分两个阶段。最初，作者根据RolandMorris残疾问卷编制了一份问卷,并将其发送给下腰痛专家委员会,使用Delphi技术进行验证.第二阶段包括将最终问卷发送给在医院环境中工作至少2年的卫生专业人员，并提出至少3个月的慢性下腰痛。结果由物理治疗师和该领域的内科医生专家（具有3年以上经验的骨科医生）组成的小组在两轮问卷调整中进行了验证。两轮都有13名参与者。问卷最初由27个项目组成，and,验证后，它有19个项目。这项研究包括65名受试者，平均年龄为40.91岁，平均每周在医院工作40小时。总样本中有76.9%的医生，10.8%的理疗师,以及12.3%的护士或护理技师。大多数(52.3%)受试者报告每天停留在影响下背部5至10小时的不舒适姿势。结论我们开发并验证了，使用Delphi技术，在医院工作的医疗保健专业人员中，关于与慢性职业性腰背痛相关的患病率和危险因素的问卷。这种前所未有的工具可以使所研究的人群受益，因为目前用于评估慢性下腰痛的问卷并不专门用于调查这种情况的职业原因。
