OBJECTIVES: In 1975, Melzack developed the McGill Pain Questionnaire (MPQ), which is composed of four major parts and evaluates the quality of pain. OBJECTIVES: The aim of this study is to assess the reliability, and validity of the MPQ on a sample of Turkish general population. METHODS: This study used the data from a Web-based questionnaire. This has been administered to 342 participants. RESULTS: The results indicate that the scale is reliable (r= 0.887). Four factors with Eigen values over one have been extracted after evaluating the factor analysis. This has accounted for 62.3% of the variance. Correlations between sensory and evaluative subscales have been low (r=0.436, p<0.01), and the most positive correlation has been seen between the miscellaneous and sensory (r=0.656, p<0.01), as well as affect subscales (r=0.601, p<0.01). Discriminate validity has been evaluated by comparing the patient and control group's scores. For miscellaneous (p=0.002) and affect (p=0.006) subscales statistical differences have been found. The correlations between MPQ (subscales and all scale) and Visual Analogue Scale point has been calculated with Spearman correlation for divergent validity. The correlation between VAS and Pain Rating Index for the patient group has been moderate (rho=0.59, p=0.000) and low for the control group (rho=0.32, p=0.000). For both groups, most strong correlation with the Visual Analogue Scale has been seen for the affect and evaluation subscales of MPQ. CONCLUSION: These results support the Turkish-MPQ as a reliable and valid measure for evaluating the quality of pain in the Turkish population. Turkish MPQ can be used in clinical researches to follow and to evaluate the patients.
