As part of a controlled clinical trial of Health Hazard Appraisal's (HHA) efficacy in stimulating risk reduction, the reliability of the HHA questionnaire was evaluated. Of 203 subjects, only 30 (15%) had no contradictions when comparing the responses of the follow-up with baseline questionnaire. Overall, there was an average of 1.6 contradictions per subject. Failure to control for reliability may account for apparent reduction of risk reported in previous studies of HHA.
作为健康危害评估（HHA）刺激风险降低功效的对照临床试验的一部分，对HHA问卷的可靠性进行了评估。在203名受试者中，将随访问卷与基线问卷的回答进行比较时，只有30名（15%）没有矛盾之处。总体而言，每位受试者平均有1.6处矛盾。未能控制可靠性可能是先前HHA研究中所报告的风险明显降低的原因。
