癌症症状评估和管理的多维度、多症状方法已在各卫生学科得到强调。然而，评估的每个维度都显著增加了患者/受试者负担。在临床和研究环境中，对患者最显著症状的关键维度进行有效、可靠和有效的评估非常重要。症状表征问卷（SRQ），来自信息处理理论，评估关键的认知和情感因素，已知的影响应对和结果。SRQ的开发和评估分为三个阶段：（1）项目选择，修改，并由理论和临床专家审查;（2）可行性和心理测量特性的初步评估;（3）大样本心理测量评估。在第3阶段，国家卵巢癌联盟的成员（n = 713）通过邮寄调查参与。所有分量表的内部一致性良好（α = 0.63-0.88）。SRQ的内部结构在理论上是一致的，除了情绪表征，身份和后果项目都加载到一个单一的因素。组间比较支持结构效度：长期生存者和活动性疾病妇女之间的代表性不同。SRQ各分量表与症状干预和生活满意度之间存在显著相关。SRQ似乎是一个心理测量学上的声音工具，用于评估癌症相关症状的表征。该工具可以发挥重要的作用，在推进知识之间的关系表示的症状，症状管理过程中，和与糖尿病相关的结果。它也可以用于干预研究时，假设症状表征的变化介导的结果作为心理教育干预的结果的变化。
Multidimensional, multisymptom approaches to cancer symptom assessment and management have been emphasized across health disciplines. However, each dimension that is assessed significantly increases patient/subject burden. Efficient, reliable, and valid assessment of the critical dimensions of patients' most salient symptoms is important in clinical and research settings. The Symptom Representation Questionnaire (SRQ), derived from information processing theory, assesses critical cognitive and emotional factors that are known to influence coping and outcomes. The SRQ was developed and evaluated in a three-phase process: (1) item selection, modification, and review by theoretical and clinical experts; (2) pilot evaluation of feasibility and psychometric properties; and (3) large sample psychometric evaluation. In Phase 3, members (n = 713) of the National Ovarian Cancer Coalition participated via mailed surveys. Internal consistency was good for all subscales (alpha = 0.63-0.88). The internal structure of the SRQ was theoretically consistent except that emotional representation, identity, and consequence items all loaded onto a single factor. Between-group comparisons supported construct validity: Representations differed between long-term survivors and women with active disease. Finally, there were significant correlations between SRQ subscales and Symptom Interference and Life Satisfaction. The SRQ appears to be a psychometrically sound instrument for assessing representations of cancer-related symptoms. This instrument could play an essential role in advancing knowledge of the relationships among representations of symptoms, symptom management processes, and symptom-related outcomes. It could also be used in intervention research when changes in symptom representations are hypothesized to mediate changes in outcomes as a result of psychoeducational interventions.
