[Validity of the Hoppe List. An empirical study of patients with backache]

Construct validity, criterion-oriented validity, and differential validity were assessed to determine the validity of the Hoppe-Liste (HL). Construct validity was ascertained by the multitrait-multimethod analysis suggested by Campbell & Fiske. Data regarding both convergent and discriminant validity show that the HL measures the construct pain. A comparison of the HL with the Revised Multidimensional Pain Scale and the Visual Analogue Scale suggests the criterion-oriented validity of the HL. Group-specific scores of the HL scales and of correlation patterns between scales tentatively support differential validity. It is concluded that the HL seems to be a suitable instrument for measuring the intensity and quality of pain.
