Validity and Reliability of Turkish Version of the Identification Pain Questionnaire in the Assessment of Neuropathic Pain.

Abstract

This study aims to assess the validity and reliability of a Turkish version of the identification (ID) pain (ID pain-T) questionnaire in Turkish patients. The Turkish version of ID pain questionnaire was obtained after translation from English into Turkish. The study included 194 patients of which 100 (34 males, 66 females; mean age 59.8±14.3 years; range, 28 to 88 years) were diagnosed as neuropathic pain (NP) and 94 (31 males, 63 females; mean age 47.2±16.5 years; range, 20 to 78 years) were diagnosed as non-neuropathic pain. Patients with mixed-type pain, cancer pain, headaches, substance abuse, severe depression or fibromyalgia syndrome were excluded. The reliability and consistency of ID pain-T questionnaire were acceptable, with a Cronbach's alpha coefficient of 0.701. Statistical analysis of the ID pain-T questionnaire calculated an optimal cut-off score of ≥2 for determining NP with a sensitivity of 77.2% and a specificity of 85%. Further, with an excellent value of 0.92 for area under the curve, a good diagnostic value was indicated. The Turkish version of ID pain questionnaire assessed in the present study is a valid and reliable self-administered questionnaire to identify NP in Turkish patients.
