The patient-doctor relationship (PDR) as perceived by the patient is an important concept in primary care and
psychotherapy. The PDR Questionnaire (PDRQ-9) provides a brief measure of the therapeutic aspects of the PDR in primary
care. We assessed the internal and external validity of the German version of the PDRQ-9 in a representative crosssectional
German population survey that included 2,275 persons aged$14 years who reported consulting with a primary
care physician (PCP). The acceptance of the German version of this questionnaire was good. Confirmatory factor analysis
demonstrated that the PRDQ-9 was unidimensional. The internal reliability (Cronbach’s a) of the total score was .95. The
corrected item-total correlations were$.94. The mean satisfaction index of persons with a probable depressive disorder was
lower than that of persons without a probable depressive disorder, indicating good discriminative concurrent criterion
validity. The correlation coefficient between satisfaction with PDR and satisfaction with pain therapy was r = .51 in 489
persons who reported chronic pain, indicating good convergent validity. Despite the limitation of low variance in the PDRQ-
9 total scores, the results indicate that the German version of the PDRQ-9 is a brief questionnaire with good psychometric
properties to assess German patients’ perceived therapeutic alliance with PCPs in public health research.
