          Abstract

          Objective

          The present study aimed to develop a culturally appropriate and functional Standard Mandarin Chinese translation of the short-form McGill Pain Questionnaire-2 (SF-MPQ-2) and to assess its reliability and validity for characterizing chronic visceral pain in Chinese patients.

          Background

          The SF-MPQ-2 has been widely used in studies of pain epidemiology, diagnosis and treatment, and even pathophysiologic mechanisms to assess the major symptoms of clinical pain. Previous reports have shown favorable reliability, validity, and responsiveness of the SF-MPQ-2 in diverse samples of patients with chronic and acute pain. However, a culturally appropriate, functional Chinese version of the scale has never been developed.

          Methods

          Beaton’s guidelines were used for the translation and back-translation procedures. Patients (n=145) with chronic visceral pain were recruited to complete the Standard Mandarin Chinese version of the SF-MPQ-2 (SF-MPQ-2-CN), of which 41 were asked to complete the SF-MPQ-2-CN a second time, 3 days after the initial visit. The test–retest reliability was quantified using the intraclass correlation coefficient (ICC), and Cronbach’s alpha was calculated to assess internal consistency. Possible components were determined by exploratory factor analysis with varimax rotation, and a value of 0.4 was considered requisite for the loading of each factor.

          Results

          The ICC for subscales ranged from 0.909 to 0.952, and that of the total scale was 0.927, suggesting excellent reliability and validity of the SF-MPQ-2-CN. Cronbach’s alpha for subscales ranged from 0.896 to 0.916, and that of the total scale was 0.836 and 0.831 for primary and secondary visits, respectively. The factor loading matrix of the SF-MPQ-2-CN ranged from 0.734 to 0.901 for each of the following subscales: continuous, intermittent, neuropathic, and affective, revealing four components similar to the original scale.

          Conclusion

          The reliability and validity of the SF-MPQ-2-CN scale are statistically acceptable for the evaluation of Chinese patients with chronic visceral pain.

          The short-form McGill Pain Questionnaire.

           R Melzack (1987)
          A short form of the McGill Pain Questionnaire (SF-MPQ) has been developed. The main component of the SF-MPQ consists of 15 descriptors (11 sensory; 4 affective) which are rated on an intensity scale as 0 = none, 1 = mild, 2 = moderate or 3 = severe. Three pain scores are derived from the sum of the intensity rank values of the words chosen for sensory, affective and total descriptors. The SF-MPQ also includes the Present Pain Intensity (PPI) index of the standard MPQ and a visual analogue scale (VAS). The SF-MPQ scores obtained from patients in post-surgical and obstetrical wards and physiotherapy and dental departments were compared to the scores obtained with the standard MPQ. The correlations were consistently high and significant. The SF-MPQ was also shown to be sufficiently sensitive to demonstrate differences due to treatment at statistical levels comparable to those obtained with the standard form. The SF-MPQ shows promise as a useful tool in situations in which the standard MPQ takes too long to administer, yet qualitative information is desired and the PPI and VAS are inadequate.
