背景和目的：健康相关生活质量（HRQL）是卒中临床试验的一个关键结果。卒中特异性HRQL量表（如SS-QOL、SIS）通常是用排除失语症患者的卒中幸存者样本开发的。我们将SS-QOL用于失语症患者，以产生卒中和失语症生活质量量表（SAQOL）。我们报告的结果从心理测量评估的初始53项SAQOL和项目减少SAQOL-39.Methods-We研究了95人与长期失语症，以评估的可接受性，可靠性和有效性的SAQOL和SAQOL-39使用标准的心理测量方法。结果支持53项SAQOL总分的信度和效度，但对假设的子领域的支持很少。使用因素分析，我们得出了一个较短的版本（SAQOL-39），确定了4个子域（身体，心理，沟通和能源）。SAQOL-39表现出良好的可接受性，内部一致性（Cronbach's alpha=0.74 ~ 0.94），重测信度（组内相关系数=0.89至0.98），结构效度（校正域-总相关，r=0.38 ~ 0.58;收敛性，r=0.55 ~ 0.67;结论SAQOL-39是一个可接受的，可靠的，有效的测量长期失语症患者的HRQL。需要进一步的测试来评估SAQOL-39的反应性，并调查其在评价性研究和常规临床实践中的有用性。
Background and Purpose-Health-related quality of life (HRQL) is a key outcome in stroke clinical trials. Stroke-specific HRQL scales (eg, SS-QOL, SIS) have generally been developed with samples of stroke survivors that exclude people with aphasia. We adapted the SS-QOL for use with people with aphasia to produce the Stroke and Aphasia Quality of Life Scale (SAQOL). We report results from the psychometric evaluation of the initial 53-item SAQOL and the item-reduced SAQOL-39.Methods-We studied 95 people with long-term aphasia to evaluate the acceptability, reliability, and validity of the SAQOL and SAQOL-39 using standard psychometric methods.Results-A total of 83 of 95 (87%) were able to complete the SAQOL by self-report; their results are reported here. Results supported the reliability and validity of the overall score on the 53-item SAQOL, but there was little support for hypothesized subdomains. Using factor analysis, we derived a shorter version (SAQOL-39) that identified 4 subdomains (physical, psychosocial, communication, and energy). The SAQOL-39 demonstrated good acceptability, internal consistency (Cronbach's alpha=0.74 to 0.94), test-retest reliability (intraclass correlation coefficient=0.89 to 0.98), and construct validity (corrected domain-total correlations, r=0.38 to 0.58; convergent, r=0.55 to 0.67; discriminant, r=0.02 to 0.27 validity).Conclusions-The SAQOL-39 is an acceptable, reliable, and valid measure of HRQL in people with long-term aphasia. Further testing is needed to evaluate the responsiveness of the SAQOL-39 and to investigate its usefulness in evaluative research and routine clinical practice.
