Abstract

Objective

This study aimed to translate and culturally adapt the Canine OwnerReported Quality of Life (CORQ) questionnaire, developed by Giuffrida et al. (2018), to evaluate the quality of life (QoL) in dogs with cancer, following World Health Organization (WHO) guidelines. The QoL is becoming increasingly important in veterinary medicine, especially in the context of companion animals diagnosed with cancer. Many existing studies use non-validated scales, resulting in a lack of reliable instruments in Spanish-speaking populations.

Methods

Construct validity and internal consistency were evaluated using factor analyses and Cronbach’s α, and convergent validity was examined against established quality-of-life measures.

Results

The findings indicate that the Spanish version of the CORQ exhibits robust psychometric properties, characterized by high internal consistency (Cronbach’s alpha = 0.841 for vitality and 0.946 for wellness) and significant correlations with established QoL measures.

Conclusions and clinical relevance

This successful adaptation and validation provides Spanish-speaking veterinarians with a reliable tool to assess and manage quality of life in dogs diagnosed with cancer.

犬主人报告的生活质量问卷（CORQ）评估癌症犬生活质量的文化适应和心理测量特性

目的：本研究旨在翻译并适应Giuffrida等人（2018）开发的犬主人报告的生活质量（CORQ）问卷，根据世界卫生组织（WHO）的指导方针评估癌症犬的生活质量（QoL）。生活质量在兽医学中变得越来越重要，特别是在被诊断患有癌症的伴侣动物的背景下。许多现有的研究使用未经验证的量表，导致在讲西班牙语的人群中缺乏可靠的工具。方法：采用因子分析和Cronbach's α对结构效度和内部一致性进行评估，并对已建立的生活质量测量进行收敛效度检验。结果：研究结果表明，西班牙语版CORQ具有强大的心理测量特性，其特点是内部一致性高（活力的Cronbach's alpha = 0.841，健康的Cronbach's alpha = 0.946），并且与已建立的生活质量测量具有显著相关性。结论和临床意义：这项成功的适应和验证为讲西班牙语的兽医提供了可靠的工具来评估和管理诊断为癌症的狗的生活质量。
