BACKGROUND
Illness perceptions may influence coping behaviors as well as treatment and recovery among patients with chronic pain including low back pain (LBP). These perceptions may vary across different conditions. The Brief Illness Perception Questionnaire (BIPQ) is used as an instrument to assess the patients' perception of illness. Although the BIPQ has been previously translated into Persian, its psychometric properties have not been evaluated among patients with chronic nonspecific LBP. The aim of this study was to determine the reliability and validity of the Persian BIPQ in patients with chronic nonspecific LBP.
METHODS
116 patients with chronic nonspecific LBP with a mean (standard deviation) age of 36.4 years (10.7) participated in this cross-sectional study. Fifty patients were reexamined after 10 to 12 days for test-retest reliability. Internal consistency reliability, construct validity, concurrent criterion validity, and structural validity were evaluated. The concurrent validity was examined by using the Short Form-36 Health Survey.
RESULTS
There were no floor and ceiling effects. Cronbach's alpha for the total score was 0.90. The intraclass correlation coefficient (ICC) for test-retest reliability was 0.90. The standard error of measurement and the minimal detectable change was found to be 3.26 and 9.04, respectively. The convergent correlations confirmed the construct validity. The concurrent criterion validity was demonstrated by significant negative correlations with the SF-36. The Exploratory Factor Analysis produced the 2 factors (emotional illness representations and cognitive illness representations) with an eigenvalue >1.0 that jointly accounted for 58.86% of the total variance.
CONCLUSION
The Persian BIPQ is a reliable and 2-factor instrument and can be used for assessing illness perception in patients with chronic nonspecific LBP.
背景
疾病认知可能会影响慢性疼痛患者（包括慢性下背痛，LBP）的应对行为以及治疗和康复。这些认知可能因不同的病症而有所不同。简短疾病认知问卷（BIPQ）是用于评估患者疾病认知的一种工具。尽管 BIPQ 之前已被译为波斯语，但它在慢性非特异性 LBP 患者中的心理测量特性尚未得到评估。本研究的目的是确定波斯语 BIPQ 在慢性非特异性 LBP 患者中的信度和效度。
方法
116 名慢性非特异性 LBP 患者参与了这项横断面研究，平均（标准差）年龄为 36.4 岁（10.7）。其中 50 名患者在 10-12 天后进行了重测以评估测试-重测信度。评估内部一致性信度、结构效度、同时效标效度和结构效度。同时效标效度通过使用 36 项简短健康调查问卷（SF-36）进行评估。
结果
无地板效应和天花板效应。总分的克朗巴赫α系数为 0.90。重测信度的组内相关系数（ICC）为 0.90。测量误差的标准误差和最小可检测变化分别为 3.26 和 9.04。聚合相关性证实了结构效度。同时效标效度通过与 SF-36 的显著负相关得到证明。探索性因子分析产生了 2 个因子（情绪疾病认知和认知疾病认知），特征值>1.0，共同解释了总方差的 58.86%。
结论
波斯语 BIPQ 是一种可靠的 2 因素工具，可用于评估慢性非特异性 LBP 患者的疾病认知。
