Abstract

Objectives

The demand for dental implants is increasing in China; however, there is currently no validated assessment tool tailored to the oral health-related quality of life among this population. This study aimed to translate the Quality of Life with Implant Prostheses scale (QoLIP-10) into Chinese and evaluate its psychometric properties, including validity and reliability.

Methods

The QoLIP-10 was translated into Chinese using the Brislin translation model. A total of 202 implant-prosthesis wearers were recruited between August 2022 and July 2023 in China. Psychometric evaluation included exploratory factor analysis (EFA), confirmatory factor analysis (CFA), criterion validity, content validity, internal consistency (Cronbach’s α), split-half reliability, and test-retest reliability.

Results

The Chinese version of QoLIP-10 was successfully adapted to align with China’s cultural context. EFA extracted two factors, explaining 68.04 % of the cumulative variance. CFA demonstrated good model fit (χ²/df = 1.600, RMSEA = 0.077, CFI = 0.981, IFI = 0.982, TLI = 0.972). Criterion validity yielded a correlation coefficient of 0.386. Content validity indices were strong, with item-level (I-CVI) and scale-level (S-CVI) values ranging from 0.80 to 1.00 and 0.96, respectively. Internal consistency was excellent (total Cronbach’s α = 0.871; subscales: 0.896 and 0.910). Split-half reliability was 0.716, and test-retest reliability (2-week interval) was 0.875.

Conclusion

The Chinese QoLIP-10 shows promising psychometric properties and potential cultural adaptability in this initial cross-sectional validation, providing a validated tool for assessing quality of life in Chinese implant-prosthesis wearers. Its two-factor structure effectively captures both functional and psychosocial impacts of treatment.

Clinical Significance

This culturally adapted instrument enables efficient clinical assessment of patient-reported outcomes, addressing a critical gap in China's growing implant dentistry practice. Its brevity (10 items) and reliability make it particularly suitable for routine monitoring in busy clinical settings.

中国种植体生活质量的信度和效度：一种评估种植体-种植体佩戴者生活质量的工具。

目的：中国对种植体的需求日益增长；然而，目前还没有针对这一人群口腔健康相关生活质量的有效评估工具。本研究旨在将种植体生活质量量表（QoLIP-10）翻译成中文，并评估其心理测量学特性，包括效度和信度。方法：采用Brislin翻译模型对QoLIP-10进行中文翻译。在2022年8月至2023年7月期间，中国共招募了202名种植义肢佩戴者。心理测量学评价包括探索性因子分析（EFA）、验证性因子分析（CFA）、效度、内容效度、内部一致性（Cronbach’s α）、分半信度和重测信度。结果：QoLIP-10的中文版成功地适应了中国的文化背景。EFA提取了两个因子，解释了68.04%的累积方差。CFA证明好的模型适合(χ²/ df = 1.600,RMSEA = 0.077,CFI = 0.981,如果 = 0.982  TLI = 0.972)。效度的相关系数为0.386。内容效度指数较强，项目水平（I-CVI）和量表水平（S-CVI）值分别在0.80 ~ 1.00和0.96之间。内部一致性极好（总Cronbach's α = 0.871；子量表：0.896和0.910）。分半信度为0.716，重测信度（2周间隔）为0.875。结论：中国QoLIP-10在初步的横断面验证中显示出良好的心理测量特性和潜在的文化适应性，为评估中国种植体-假体佩戴者的生活质量提供了一种有效的工具。它的双因素结构有效地捕获了治疗的功能和社会心理影响。临床意义：这种适应文化的仪器能够对患者报告的结果进行有效的临床评估，解决了中国种植牙科实践中日益增长的关键差距。它的简洁性（10项）和可靠性使其特别适合在繁忙的临床环境中进行常规监测。

期刊介绍： The Journal of Dentistry has an open access mirror journal The Journal of Dentistry: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The Journal of Dentistry is the leading international dental journal within the field of Restorative Dentistry. Placing an emphasis on publishing novel and high-quality research papers, the Journal aims to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. Topics covered include the management of dental disease, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research. The Journal of Dentistry will publish original scientific research papers including short communications. It is also interested in publishing review articles and leaders in themed areas which will be linked to new scientific research. Conference proceedings are also welcome and expressions of interest should be communicated to the Editor.
