Single item presenteeism question (SIPQ) is a rating scale to assess the impact of low back pain (LBP) on presenteeism.
To translate the SIPQ into Persian language (SIPQ-P) and evaluate the reliability and validity of the SIPQ-P in participants with LBP.
In the first stage, the English SIPQ was translated into Persian language in a cross-sectional design following standard forward-backward approach with expert panel review and pilot testing. In the second stage with a prospective cohort design, 100 participants with LBP (84 male and 16 female, mean age±SD: 33.9±11.2 years) participated. Participants were asked to answer the SIPQ-P and rate their LBP from 0 to 10 according to the numerical pain rating scale (NPRS) for concurrent criterion validity. To evaluate the convergent construct validity of SIPQ, participants completed Persian Functional Rating Index (PFRI). For the divergent validity, the Spearman's correlation test was used to evaluate the association between the SIPQ-P and education. For the test-retest reliability, 50 participants answered the SIPQ-P after 7 days. Fifty healthy participants (mean age±SD: 24.24±8.07 years) answered the SIPQ-P for evaluating discriminant validity.
There was a significant difference between the SIPQ-P score of participants and the healthy participants (p < 0.001). The concurrent criterion validity was demonstrated by a significant correlation between the SIPQ-P and pain NPRS (Spearman's rho = 0.46, p < 0.001). The Spearman correlation coefficient showed a significant correlation between the SIPQ-P scores and the Persian FRI (r = 0.56, p < 0.001). There was no correlation between the SIPQ-P score and the education level (r = -0.001, p = 0.99). The ICCagreement was 0.77 indicating a very good test-retest reliability.
This study showed that the Persian version of SIPQ is a reliable and valid scale to assess the effect of LBP on presenteeism in Persian speakers with LBP.
单项出勤主义问题量表（SIPQ）是一种用于评估腰痛（LBP）对出勤主义影响的评定量表。
将SIPQ翻译成波斯语（SIPQ-P），并评估SIPQ-P在腰痛患者中的信效度。
第一阶段，采用标准的前后翻译法，经专家小组审核和预试验，将英文SIPQ翻译成波斯语。第二阶段采用前瞻性队列设计，100例腰痛患者（84例男性，16例女性，平均年龄±标准差：33.9±11.2岁）参与研究。要求参与者回答SIPQ-P，并根据数字疼痛评定量表（NPRS）对其腰痛程度进行0至10分的评分，以评估同时效度。为评估SIPQ的收敛效度，参与者完成波斯语功能评定指数（PFRI）。为评估区分效度，采用Spearman相关检验评估SIPQ-P与教育程度之间的关联。为评估重测信度，50例参与者在7天后再次回答SIPQ-P。50例健康参与者（平均年龄±标准差：24.24±8.07岁）回答SIPQ-P以评估区分效度。
参与者与健康参与者的SIPQ-P得分存在显著差异（p<0.001）。SIPQ-P与疼痛NPRS之间存在显著相关性，证明了同时效度（Spearman相关系数ρ=0.46，p<0.001）。Spearman相关系数显示SIPQ-P得分与波斯语FRI之间存在显著相关性（r=0.56，p<0.001）。SIPQ-P得分与教育水平之间无相关性（r=-0.001，p=0.99）。组内相关系数（ICC）一致性为0.77，表明重测信度非常好。
本研究表明，波斯语版SIPQ是一种可靠且有效的量表，可用于评估腰痛对说波斯语的腰痛患者出勤主义的影响。
