PROMIS 1 American Chronic Pain Association (ACPA) Supplement

In order to increase the number of participants experiencing pain in the calibration sample, individuals with chronic pain were recruited through the American Chronic Pain Association (ACPA). An invitation to complete the PROMIS pain survey was posted on the ACPA website. To be eligible, participants had to be 21 years of age or older and have at least one chronic pain condition for at least 3 months prior to participating in the survey. Those who met eligibility criteria were asked to complete an online informed consent form. After obtaining informed consent, participants immediately began the survey. The survey was posted on the website of the ACPA from September 2007 to March 2008. There were 967 participants who responded to 47 Pain Interference, 42 pain behavior, and 41 pain quality items, and one global average pain intensity item through online administration. The average age was 48.2 years (SD = 11.1). Eighty-one percent of the respondents were female, and 91% were Caucasian, 1.5% were African-American, and 5% were of Hispanic origin. Eighty-one percent of the participants had an education equal to or greater than high school. The data was combined with the Calibration Studies full-bank test data to calculate item calibrations.为提升校准样本中疼痛体验参与者的规模，本研究通过美国慢性疼痛协会（American Chronic Pain Association，ACPA）招募慢性疼痛患者，并在该协会官网发布了填写PROMIS疼痛问卷（PROMIS pain survey）的邀请。参与者需满足以下资格条件：年满21周岁，且在参与调查前至少罹患3个月及以上的慢性疼痛病症。符合资格标准的参与者需填写线上知情同意书，在获取知情同意后，参与者即刻开始完成问卷。该问卷于2007年9月至2008年3月期间在ACPA官网上线。共有967名参与者通过线上方式完成调查，其中涵盖47项疼痛干扰条目、42项疼痛行为条目、41项疼痛质量条目，以及1项整体平均疼痛强度条目。参与者的平均年龄为48.2岁（标准差=11.1）。81%的受访者为女性，91%为白人，1.5%为非裔美国人，5%为西班牙裔血统。81%的参与者受教育程度达到高中及以上水平。本研究将该数据集与校准研究全库测试数据合并，以计算条目校准值。
