This study assessed the test-retest reliability/repeatability and 95 percent confidence intervals (CIs) of the Tinnitus Handicap Inventory (THI) and developed categories for classifying self-perceived tinnitus handicap severity. Twenty-nine adults with tinnitus as their primary auditory complaint served as subjects. The THI was administered on two occasions (mean interval 20 days) using a paper-pencil format. Results support the contention that the THI is psychometrically robust. Specifically, the test-retest reliability/repeatability was high. Additionally, the 95 percent CI for the THI was 20-points, indicating that a 20-point or greater change had to occur from test to retest for a change to be considered statistically significant at the 5 percent confidence level. Quartiles calculated from raw scores were used to create a matrix of values representing tinnitus severity. We conclude that the THI is a brief, easily administered, and psychometrically robust measure that evaluates the impact of tinnitus on daily living.
本研究评估了耳鸣障碍量表（THI）的重测信度/可重复性及95%置信区间（CI），并制定了用于对自我感知的耳鸣障碍严重程度进行分类的类别。29名以耳鸣作为主要听觉主诉的成年人作为研究对象。采用纸笔形式分两次（平均间隔20天）施测THI。结果支持了THI在心理测量学上具有稳健性这一观点。具体而言，重测信度/可重复性较高。此外，THI的95%CI为20分，这表明从测试到重测必须出现20分或更大的变化，该变化才会在5%置信水平上被视为具有统计学显著性。根据原始分数计算的四分位数被用于创建一个代表耳鸣严重程度的数值矩阵。我们得出结论，THI是一种简短、易于施测且在心理测量学上稳健的测量工具，可用于评估耳鸣对日常生活的影响。
