The Ibadan Low Back Pain Disability Questionnaire (ILBPDQ) was developed to meet the need for a LBP treatment outcome measure that was appropriate for the Nigerian culture and environment. The objective of this study was to determine the psychometric properties of ILBPDQ.
This study used the validation design. One hundred and forty-two participants with LBP (LBPPs) and 142 age and sex-matched participants without LBP (NLBPPs) were included. The LBPPs were recruited consecutively from Physiotherapy clinics of selected tertiary hospitals in the six geopolitical zones of Nigeria. Both LBPPs and NLBPPs completed the ILBPDQ - the LBPPs completed the Numerical Pain Rating Scale (NPRS). The ILBPDQ was completed by 113 LBPPs two days after initial assessment. Sixty-four of the LBPPs received physiotherapy for 5-weeks, after which they were reassessed using ILBPDQ and NPRS.
ILBPDQ score of LBPPs was significantly higher than that of NLBPPs (construct validity) and LBPPs NPRS score correlated significantly with their ILBPDQ score (r = 0.50) at baseline and post intervention (r =0.35) (divergent validity). ILBPDQ scores at baseline and 48 hours later for LBPPs correlated significantly (Intra Class Correlation =0.80) (test re -test reliability). Cronbach's α for ILBPDQ was 0.84 (internal consistency). The postintervention ILBPDQ and NPRS scores for LBPPs were significantly lower than their pre-intervention ILBPDQ scores (responsiveness) and NPRS scores. The changes in ILBPDQ and NPRS scores of the LBPPs correlated significantly (r =0.62) (responsiveness).
The ILBPDQ demonstrated evidence of validity, reliability and responsiveness.

伊巴丹下腰痛残疾问卷（ILBPDQ）的开发是为了满足对一种适合尼日利亚文化和环境的下腰痛治疗效果测量工具的需求。本研究的目的是确定ILBPDQ的心理测量特性。
本研究采用效度验证设计。纳入了142名下腰痛患者（LBPPs）和142名年龄及性别匹配的无下腰痛参与者（NLBPPs）。LBPPs是从尼日利亚六个地缘政治区选定的三级医院的物理治疗诊所连续招募的。LBPPs和NLBPPs都完成了ILBPDQ——LBPPs完成了数字疼痛评分量表（NPRS）。113名LBPPs在初次评估两天后完成了ILBPDQ。64名LBPPs接受了为期5周的物理治疗，之后使用ILBPDQ和NPRS对他们进行重新评估。
LBPPs的ILBPDQ得分显著高于NLBPPs（结构效度），LBPPs的NPRS得分在基线和干预后与他们的ILBPDQ得分显著相关（r = 0.50）（区分效度，干预后r = 0.35）。LBPPs在基线和48小时后的ILBPDQ得分显著相关（组内相关系数 = 0.80）（重测信度）。ILBPDQ的Cronbach's α为0.84（内部一致性）。LBPPs干预后的ILBPDQ和NPRS得分显著低于他们干预前的ILBPDQ得分（反应度）和NPRS得分。LBPPs的ILBPDQ和NPRS得分变化显著相关（r = 0.62）（反应度）。
ILBPDQ显示出效度、信度和反应度的证据。
