To develop a self-report questionnaire for persons with lower limb amputations who use a prosthesis. The resulting scales were intended to be suitable to evaluate the prosthesis and life with the prosthesis. The conceptual framework was health-related quality of life.
Multiple steps of scale development, terminating with test-retest of the Prosthesis Evaluation Questionnaire (PEQ) by mail. SOURCE OF SAMPLE: Records from two Seattle hospitals.
Ninety-two patients with lower limb amputations who varied by age, reason for amputation, years since amputation, and amputation level.
The 10 scales used were 4 prosthesis function scales (Usefulness, Residual Limb Health, Appearance, and Sounds), 2 mobility scales (Ambulation and Transfers), 3 psychosocial scales (Perceived Responses, Frustration, and Social Burden), and 1 Well-being scale. Validation measures were the Medical Outcomes Study Short Form-36, the Social Interaction subscale from the Sickness Impact Profile, and the Profile of Mood States-short form.
Nine PEQ scales demonstrated high internal consistency. All met test-retest criteria for comparing group results. Validity was described based on methods used to gather original items, distribution of scores, and comparison of scores with criterion variables.
The PEQ scales displayed good psychometric properties. Future work will assess responsiveness of PEQ scales to changes in prosthetic components. We conclude that they will be useful in evaluation of prosthetic care.
为使用假肢的下肢截肢患者开发一份自我报告问卷。所得量表旨在适用于评估假肢及使用假肢的生活情况。概念框架为健康相关生活质量。
量表开发的多个步骤，最终通过邮件对假肢评估问卷（PEQ）进行重测。样本来源：西雅图两家医院的记录。
92例下肢截肢患者，他们在年龄、截肢原因、截肢后年限及截肢水平方面存在差异。
所使用的10个量表分别为4个假肢功能量表（有用性、残肢健康、外观及声音）、2个活动量表（行走及转移）、3个心理社会量表（感知反应、挫折感及社会负担）和1个幸福感量表。验证指标为医学结局研究简明健康调查36项量表、疾病影响量表中的社会互动子量表以及情绪状态量表简表。
9个PEQ量表显示出较高的内部一致性。所有量表均符合比较组结果的重测标准。基于收集原始条目的方法、分数分布以及与标准变量的分数比较对效度进行了描述。
PEQ量表显示出良好的心理测量特性。未来的工作将评估PEQ量表对假肢部件变化的反应性。我们得出结论，它们将有助于评估假肢护理。
