目的测试方法，以优化邮件调查的响应和授权率(即，允许一个人的调查与医疗记录相关联)，当调查敏感且目标人群有精神障碍时。研究设计和设置在美国中西部退伍军人事务医疗中心接受创伤后应激障碍(PTSD)治疗的1,099名退伍军人的随机对照试验。受试者被随机分为三组：(1)在调查中嵌入《健康保险携带与责任法案》(HIPAA)授权表(勾选同意)；(2)在调查结束后发送HIPAA授权表，要求签名表示同意；(3)要求签名和社会保障号码(SSN)的HIPAA表在调查结束后发送。在问卷返回后要求受访者签名和SSN产生的调查回复率最高(74.2%)，但授权率最低(48.7%)。但有效率差异无统计学意义。报告的情绪不安程度较低(1.5%)，主要针对调查，而不是HIPAA表格。年龄越大，信任度越高，授权率越高。结论即使采用了我们最优化的策略，授权率也低得令人失望。
OBJECTIVESTo test methods to optimize mail survey response and authorization rates (i.e., allowing one's survey to be linked to medical records) when the survey is sensitive and the targeted population has a mental disorder.STUDY DESIGN AND SETTINGRandomized controlled trial of 1,099 veterans treated for posttraumatic stress disorder (PTSD) at a Midwestern Veteran Affairs Medical Center. Subjects were randomized to one of three groups: (1) Health Insurance Portability and Accountability Act (HIPAA) authorization form embedded in the survey (checking “yes” for consent); (2) HIPAA form requiring signature for consent sent after the survey; or (3) HIPAA form requiring a signature and social security number (SSN) for consent sent after the survey.RESULTSThe “embedded” strategy yielded the lowest survey response rate (67.5%) but highest authorization rate (59.1%). Requiring respondents' signatures and SSNs after the survey was returned generated the highest survey response rate (74.2%) but lowest authorization rate (48.7%). However, the response rate difference was not statistically significant. Reported emotional upset was low (1.5%) and primarily directed to the survey, not the HIPAA form. Older age and greater trustfulness were associated with higher authorization rates.CONCLUSIONEven with our most optimized strategy, authorization rates were disappointingly low.
