For research into tinnitus to be robust and credible, the use of well-validated instruments of self-perceived tinnitus handicap as outcome measures is essential. The tinnitus handicap inventory (THI) and the tinnitus questionnaire (TQ) are two such instruments which are in widespread use. Both questionnaires were administered by mail to 100 consecutive new patients of the Cambridge Tinnitus Clinic, and completed in randomized order. These patients had been referred by the otolaryngology team and had not undergone any tinnitus therapy. The response rate was 78 per cent, neither questionnaire being more acceptable to patients than the other. The convergent validity of the instruments was high, with total and subscale scores all being significantly correlated at the five per cent level (Spearman correlation coefficients). A number of subscale scores were not significantly correlated at the one per cent level however. In particular, the sleep disturbance element of the TQ was demonstrated to have some discriminant validity from the THI and from other elements of the TQ at the one per cent significance level. The THI and TQ have been demonstrated to have high convergent validity and are both suitable for tinnitus outcome studies involving the quantification of self-perceived tinnitus handicap. For research that aims to determine the specific effect of an intervention on tinnitus-related sleep disturbance, the TQ sleep subscale has potential utility. The hypothetical constructs of tinnitus handicap underlying the psychologist-developed TQ and the audiologist-developed THI have been shown to be convergent.
为使耳鸣研究稳健且可信，使用经过充分验证的自我感知耳鸣障碍测量工具作为结果指标至关重要。耳鸣障碍问卷（THI）和耳鸣问卷（TQ）就是两种广泛使用的此类工具。两份问卷均通过邮寄方式发放给剑桥耳鸣诊所连续的100名新患者，并按随机顺序填写。这些患者由耳鼻喉科团队转诊而来，且未接受过任何耳鸣治疗。回复率为78%，两份问卷在患者接受度上并无差异。这些工具的收敛效度较高，总分及各子量表得分在5%水平上均显著相关（斯皮尔曼相关系数）。然而，一些子量表得分在1%水平上并无显著相关性。特别是，TQ的睡眠干扰部分在1%显著性水平上显示出与THI以及TQ的其他部分具有一定的区分效度。THI和TQ已被证明具有较高的收敛效度，均适用于涉及自我感知耳鸣障碍量化的耳鸣结果研究。对于旨在确定干预对耳鸣相关睡眠干扰具体影响的研究，TQ睡眠子量表具有潜在用途。心理学家开发的TQ和听力学家开发的THI背后的耳鸣障碍假设结构已被证明是趋同的。
