ABSTRACT
There is a growing amount of evidence that alteration in pain processing by the peripheral and central nervous system play a role in osteoarthritis pain, leading to neuropathic-like symptoms. It is essential to identify knee and hip osteoarthritis patients with a neuropathic pain profile in order to offer such patients education and additional treatment options besides conventional pain treatment. The painDETECT Questionnaire is a self-report questionnaire developed to discriminate between nociceptive and neuropathic pain. This questionnaire was modified to fit patients suffering from knee osteoarthritis. The aim of this study was to translate and cross-culturally adapt the modified painDETECT Questionnaire to the Dutch language and to provide a modified version to fit patients with hip osteoarthritis. Reliability for internal consistency, repeatability and floor and ceiling effects were subsequently assessed. A total of 278 patients were included in the reliability study and 123 patients in the repeatability analysis. The Dutch modified painDETECT Questionnaire shows good internal consistency and small relative measurement errors, represented by a good intraclass correlation coefficient. Absolute measurement error, represented by the Standard Error of Measurement, was acceptable. However, a measurement bias might be present when it comes to repeatability. To our knowledge, this study is the first to provide a Dutch modified painDETECT Questionnaire to fit hip and knee osteoarthritis patients and to assess internal consistency, reliability and agreement. International guidelines were followed in the translation process and this study has ample sample size with an adequate time interval for repeatability. Based on this study, the Dutch modified painDETECT Questionnaire seems to be fit as a discriminative tool to identify knee and hip osteoarthritis patients with a neuropathic pain profile. Whether it is also suitable as an evaluative tool to record changes over time or after an intervention remains open to further investigation.

Bland Altman plot with 95% confidence interval (CI).Vertical axis: difference between mPDQ test and retest. Horizontal axis: mean mPDQ-NL when combining test and retest. The horizontal line represents the mean difference between test and retest. The gray lines represent the 95% CI of this mean difference. Notice that the 95% CI approaches 0.00.

The horizontal line represents the mean difference between test and retest. The gray lines represent the 95% CI of this mean difference. Notice that the 95% CI approaches 0.00.

Mentions: Table 2 presents repeatability results for the mPDQ-NL. For total scores the SEM was 2.6, the SDCind 7.3 and the SDCgroup 0.7. For individual items, SEM value ranges were 0.5–0.9, SDCind ranges 1.1–2.6 and SDCgroup 0.1–0.3. For the total score, the mean difference between test and retest was 0.69 with a 95% CI of 0.03–1.36, which therefore did not contain zero. For individual items, the 95% CI contained zero for most individual items, except for radiation and sudden pain attacks. The Bland Altman plot is presented in Fig 2. For the total score, ICC was 0.90. For individual items ICC was high for most pain quality items (>0.70), except for pain pattern (ICC 0.52) and radiation (ICC 0.67).
