目的：期望已被证明会影响心理和医疗干预的反应，然而，缺乏有效的措施，预期在设置针灸限制了定量评估的期望对针灸治疗的临床反应的影响。本研究旨在开发和验证一种测量患者对针灸治疗的预期反应的工具。设置/设计：我们通过从患者中引出项目来开发针灸治疗预期量表，然后分两个阶段在中国北京的6个针灸门诊的200名受试者中进行调查研究，以检验该工具的信度和效度。我们最终的量表包括四个项目，测量疾病改善的期望，增强应对，增加活力，并作为针灸治疗的结果症状缓解。针灸期望量表的得分范围从4到20，中位数为17，最高得分为21%。没有一个项目的缺失数据超过5%。内部一致性（Cronbach's alpha系数）为0.82。主成分分析显示，一个一般成分占64%的方差。对反应的期望与所选的感知疗效（0.44）、满意度（0.49）和对处方针灸治疗的信心（0.51）的问题呈正相关，均P
Objective: Expectancy has been shown to affect the response to psychological and medical interventions; however, the lack of validated measure of expectancy in the setting of acupuncture limits the quantitative evaluation of the effects of expectancy on clinical response to acupuncture therapy. We seek to develop and validate an instrument that measures patients' expected response from acupuncture.Setting/design: We developed the acupuncture expectancy scale by eliciting items from patients and then conducted a survey study in two phases to test the reliability and validity of the instrument among 200 subjects at six outpatient acupuncture clinics in Beijing, China.Results: Our final scale consisted of four items measuring the expectation of improvement of illness, enhanced coping, increased vitality, and symptom alleviation as a result of acupuncture therapy. Scores of acupuncture expectancy scales ranged from four to 20, with a median of 17, and 21% at the maximum score. No item had over 5% missing data. Internal consistency (Cronbach's alpha coefficient) was .82. Principal components analysis revealed one general component accounting for 64% of the variance. Expectancy of response was positively correlated with selected questions of perceived efficacy (0.44), satisfaction (0.49), and confidence in prescribed acupuncture therapy (0.51), all with P
