Abstract

Objective

To analyze the psychometric properties of the Pictorial Pain Interference Questionnaire (PPIQ) for evaluating functional interference in the population with chronic low back pain (CLBP).

Design

Cross-sectional study.

Setting

Rehabilitation Unit in a hospital.

Participants

Ninety-nine patients with CLBP.

Interventions

Not applicable.

Main Outcome Measures

Functional interference was assessed using PPIQ. The following data were also collected: sociodemographic data; pain intensity (Numeric Pain Rating Scale [NPRS]); physical functioning (30-s arm curl, 30-s chair stand [30CST], and timed Up and Go [TUG] tests), fitness (International Physical Activity Questionnaire); quality of life (Short-Form 12 Health Survey version 1 [SF-12v1]); sleep quality (Spanish-validated 12-item Medical Outcomes Study Sleep scale [12-MOS Sleep]); anxiety and depression (Hospital Anxiety and Depression Scale [HADS]); and social support (Duke-UNK Functional Social Support Questionnaire). Internal consistency was analyzed using Cronbach's alpha, structural validity using exploratory factor analysis (EFA), and discriminant and convergent validity using bivariate analysis.

Results

Ninety-nine patients with CLBP were included (age [mean ± SD]: 54.37±12.44 y); women, 67.7%). The EFA extracted 2 factors: “physical function and “social and sleep,” which explained 57.75% of the variance. Excellent internal consistency was observed for the overall PPIQ score (Cronbach's α=0.866). Convergent validity was observed between the PPIQ and other functional measures (ρ: 0.52 and −0.47 for the TUG and 30CST, respectively; P<.001) and with the following variables: physical and mental component summaries of the SF-12v1 (ρ: −0. 55 and −0.52, respectively (P<.001); anxiety and depression of the HADS (ρ: 0.47 and 0.59, respectively (P<.001); NPRS (ρ: 0.45; P<.001); and index 9 of the 12-MOS Sleep scale (r: 0.49; P<.001).

Conclusions

The PPIQ is a valid instrument with good psychometric properties for measuring functional interference in people with CLBP. This questionnaire appears to be a feasible alternative when language or communication barriers exist in CLBP population.

用于评估慢性腰背痛功能干扰的图形疼痛干扰问卷的心理计量特性。

目的分析图画式疼痛干扰问卷（PPIQ）在评估慢性腰背痛（CLBP）患者功能干扰方面的心理计量特性：设计：横断面研究：地点：加的斯Puerta del Mar医院：干预措施：不适用：主要结果测量使用 PPIQ 评估功能干扰。还收集了以下数据社会人口学数据；疼痛强度（数字疼痛评分量表 [NPRS]）；身体功能（30 秒卷臂 [30ACT]、30 秒椅站 [30CST] 和定时起立行走 [TUG] 测试）；体能（国际体力活动问卷 [IPAQ]）；生活质量（SF-12v1）、睡眠质量（12-MOS 睡眠）、焦虑和抑郁（医院焦虑抑郁量表 [HADS]）以及社会支持（杜克-UNK 功能性社会支持问卷 [DUKE-UNC-DSSI]）。采用 Cronbach's alpha 分析内部一致性，采用探索性因素分析 (EFA) 分析结构效度，采用双变量分析分析判别效度和收敛效度：共纳入 99 名 CLBP 患者（平均年龄：54.37（标清：12.44）；女性占 67.7%）。EFA 提取了两个因子：身体功能 "和 "社交与睡眠 "这两个因子解释了 57.75% 的方差。PPIQ 总分的内部一致性极佳（Cronbach's α=0.866）。在 PPIQ 和其他功能测量之间观察到了收敛有效性（rho：TUG 和 30CST 分别为 0.52 和 -0.47；P 结论：PPIQ 是一种有效的工具，在测量慢性阻塞性肺病患者的功能干扰方面具有良好的心理测量特性。当 CLBP 患者存在语言或交流障碍时，该问卷似乎是一种可行的替代方法。

期刊介绍： The Archives of Physical Medicine and Rehabilitation publishes original, peer-reviewed research and clinical reports on important trends and developments in physical medicine and rehabilitation and related fields. This international journal brings researchers and clinicians authoritative information on the therapeutic utilization of physical, behavioral and pharmaceutical agents in providing comprehensive care for individuals with chronic illness and disabilities. Archives began publication in 1920, publishes monthly, and is the official journal of the American Congress of Rehabilitation Medicine. Its papers are cited more often than any other rehabilitation journal.
