Low back pain patients' responses to the McGill Pain Questionnaire were factor analyzed using a method of factor extraction which, relative to the procedures employed in previous investigations, minimized distortion of the factor solution. Four factors were found which accounted for 51% of the total variance. Three of the factors were composed solely of(More)
Low back pain patients' responses to the McGill Pain Questionnaire (MPQ) were factor analyzed using the principal factor method and direct oblique rotation procedures. Four factors were extracted that accounted for 55% of the total variance. Coefficients of congruence were computed in order to relate the current factors with those extracted in a previous(More)
