Currently, there are no outcome measures assessing the ability of people with non-specific low back pain to self-manage their illness. Inspired by the 'Patient Enablement Instrument', we developed the Patient Enablement Instrument for Back Pain (PEI-BP). The aim of this study was to describe the development of the Patient Enablement Instrument for Back Pain (PEI-BP) and investigate content validity, construct validity, internal consistency, test-retest reliability, measurement error, responsiveness and floor and ceiling effects.
The PEI-BP consists of 6 items that are rated on a 0-10 Numeric Rating Scale. Measurement properties were evaluated using the COSMIN taxonomy and were based on three cohorts from primary care with low back pain: The content validity cohort (N = 14) which participated in semi-structured interviews, the GLA:D® Back cohort (N = 272) and the test-retest cohort (N = 37) which both completed self-reported questionnaires. For construct validity and responsiveness, enablement was compared to disability (Oswestry Disability Index), back pain beliefs (Brief Illness Perception Questionnaire), fear avoidance (Fear-Avoidance Beliefs Questionnaire-physical activity), mental health (SF-36), educational level and number of previous episodes of low back pain.
The PEI-BP was found to have acceptable content validity, construct validity, reliability (internal consistency, test-retest reliability and measurement error) and responsiveness. The Smallest Detectable Change was 10.1 points illustrating that a patient would have to change more than 1/6 of the scale range for it to be a true change. A skewed distribution towards the high scores were found at baseline indicating a potentially problematic ceiling effect in the current population.
The PEI-BP can be considered a valid and reliable tool to measure enablement on people seeking care for non-specific LBP. Further testing of the PEI-BP in populations with more severe LBP is recommended.

目前，尚无评估非特异性腰痛患者自我管理疾病能力的结局测量工具。受“患者赋权工具”的启发，我们开发了腰痛患者赋权工具（PEI-BP）。本研究旨在描述腰痛患者赋权工具（PEI-BP）的开发过程，并考察其内容效度、结构效度、内部一致性、重测信度、测量误差、反应度以及界值效应和天花板效应。
PEI-BP 由 6 个项目组成，每个项目均采用 0-10 的数字评定量表进行评分。采用 COSMIN 分类学评价测量学特性，研究对象来自初级保健的腰痛患者，包括：参与半结构式访谈的内容效度队列（n=14）、GLA:D®Back 队列（n=272）和完成自我报告问卷的重测队列（n=37）。为了考察结构效度和反应度，将赋权与残疾（Oswestry 残疾指数）、腰痛信念（简明疾病感知问卷）、恐惧回避（恐惧-回避信念问卷-体力活动）、心理健康（SF-36）、教育水平和腰痛发作次数进行比较。
PEI-BP 具有可接受的内容效度、结构效度、信度（内部一致性、重测信度和测量误差）和反应度。最小可检测变化为 10.1 分，表明患者的量表评分变化超过 1/6 分才可能是真实变化。在基线时，高分的偏度分布表明当前人群可能存在潜在的天花板效应问题。
PEI-BP 可作为一种评估非特异性腰痛患者赋权水平的有效、可靠工具。建议在腰痛更严重的人群中进一步测试 PEI-BP。
