STUDY DESIGN
Outcome investigation to verify the internal consistency, reproducibility and validity of the adapted Chinese version of the Scoliosis Research Society-22 (SRS-22) questionnaire for measuring health-related quality of life (HRQoL) in children with idiopathic scoliosis.
OBJECTIVE
To develop this questionnaire for the outcome measurement in treating Chinese adolescents with idiopathic scoliosis and evaluate its metric qualities. The SRS-22 questionnaire has proven to be a valid instrument for clinical assessment of patients with idiopathic scoliosis and has been successfully translated into Spanish and Turkish. In most developing countries, however, quality of life and psychological health have been poorly described when treating children with idiopathic scoliosis.
METHODS
Trans-cultural adaptation of the SRS-22 questionnaire was carried out according to the International Quality of Life Assessment Project guidelines. The final version was approved by a committee of experts. The questionnaire was completed by 86 adolescents with idiopathic scoliosis who had been treated with a brace; this included 11 males and 75 females, aged from 10 to 18 years (mean 13.9 years). Curve magnitude ranged from 25 degrees to 45 degrees (mean 35.6 degrees ). A subgroup of 30 patients completed the questionnaire again in 3 or 4 weeks.
RESULTS
Five common factors were acquired from factorial analysis, and the cumulative contribution ratio was 67.66%. The overall alpha coefficient of the questionnaire was 0.88. Coefficients for individual domains were as follows: function/activity, 0.70; pain, 0.80; self-image, 0.80; mental health, 0.88; and satisfaction, 0.81. The questionnaire as a whole had a test-retest correlation coefficient of 0.97. Test-retest correlation coefficients for individual domains were as follows: function, 0.85; pain, 0.96; self-image, 0.96; mental health, 0.95; and satisfaction, 0.91.
CONCLUSION
The Chinese version of the SRS-22 questionnaire is eligible in terms of reliability and validity, and can be used to measure HRQoL for adolescent idiopathic scoliosis patients in Mainland China.
研究设计
进行结果调查，以验证脊柱侧弯研究学会22项问卷（SRS - 22）中文版在测量特发性脊柱侧弯儿童健康相关生活质量（HRQoL）方面的内部一致性、可重复性和有效性。
目的
开发此问卷用于评估中国青少年特发性脊柱侧弯的治疗效果并评估其度量质量。SRS - 22问卷已被证明是评估特发性脊柱侧弯患者临床情况的有效工具，并且已成功翻译成西班牙语和土耳其语。然而，在大多数发展中国家，治疗特发性脊柱侧弯儿童时，生活质量和心理健康方面的描述较少。
方法
根据国际生活质量评估项目指南对SRS - 22问卷进行跨文化改编。最终版本经专家委员会批准。86名接受支具治疗的青少年特发性脊柱侧弯患者完成了问卷；其中包括11名男性和75名女性，年龄在10至18岁之间（平均13.9岁）。侧弯度数范围为25度至45度（平均35.6度）。30名患者组成的一个亚组在3或4周后再次完成问卷。
结果
通过因子分析获得了五个共同因素，累积贡献率为67.66%。问卷的总体α系数为0.88。各个领域的系数如下：功能/活动，0.70；疼痛，0.80；自我形象，0.80；心理健康，0.88；满意度，0.81。问卷整体的重测相关系数为0.97。各个领域的重测相关系数如下：功能，0.85；疼痛，0.96；自我形象，0.96；心理健康，0.95；满意度，0.91。
结论
SRS - 22问卷中文版在信度和效度方面符合要求，可用于测量中国大陆青少年特发性脊柱侧弯患者的健康相关生活质量。
