Common symptoms after thyroidectomy include voice change and throat and neck discomfort. But no common questionnaire has been developed. This study was performed to evaluate the reliability and validity of the Thyroidectomy-related Voice and Symptom Questionnaire (TVSQ).
Fourty items of the TVSQ were divided into 20 items related to the "voice change" and "throat and neck discomfort" subcategories, using item generation. Through a reduction process, 20 items were removed and 20 items were used. For the patients after thyroidectomy, we evaluated the reliability and validity of each of the 20 items through item discrimination, test-retest reliability, concurrent validity, and external validity by comparing normal group and laryngeal disease patients. Also, the patients were compared before as well as 2 and 4 weeks after thyroidectomy.
Item discrimination assessment showed a significant correlation between TVSQ total score and both the TVSQ "voice change" score (r = 0.908**) and TVSQ "throat and neck discomfort" score (r = 0.862**). Test-retest reliability assessment showed a significant correlation between TVSQ total scores at 2 and 4 weeks postoperatively (r = 0.764**). Concurrent validity assessment revealed that the TVSQ showed high correlations with other voice questionnaires (Voice Handicap Index, Reflux Finding Index, and Vocal Track Discomfort Scale; r = 0.538**-0.830**). External validity assessment revealed that the TVSQ was suitable for patients after thyroidectomy (P < 0.000**).
Validity and reliability tests revealed that the TVSQ was suitable for assessment of the subjective feelings of patients with voice change and throat and neck discomfort after thyroidectomy.
甲状腺切除术后常见的症状包括声音改变和咽喉颈部不适。但目前尚无通用问卷对此进行评估。本研究旨在评价甲状腺切除术相关的嗓音和症状问卷（TVSQ）的信度和效度。
采用条目生成的方法将 TVSQ 的 40 个条目分为“嗓音改变”和“咽喉颈部不适”两个亚类的 20 个条目。通过简化过程，删除了 20 个条目，保留了 20 个条目。对于甲状腺切除术后的患者，通过条目鉴别力、重测信度、同时效度和外部效度评估来评价 20 个条目的信度和效度，比较正常组和喉部疾病患者。同时，患者在甲状腺切除术前、术后 2 周和 4 周进行比较。
条目鉴别力评估显示 TVSQ 总分与 TVSQ“嗓音改变”评分（r=0.908**）和 TVSQ“咽喉颈部不适”评分（r=0.862**）呈显著相关。重测信度评估显示术后 2 周和 4 周 TVSQ 总分之间呈显著相关（r=0.764**）。同时效度评估显示 TVSQ 与其他嗓音问卷（嗓音障碍指数、反流发现指数和嗓音轨迹不适量表）高度相关（r=0.538**-0.830**）。外部效度评估显示 TVSQ 适用于甲状腺切除术后的患者（P<0.000**）。
信度和效度检验表明，TVSQ 适用于评估甲状腺切除术后嗓音改变和咽喉颈部不适患者的主观感受。
