[Questionnaire on emotional response after organ transplantation: German validation of the Transplant Effect Questionnaire (TxEQ-D)].

Objectives: The present study investigates a) whether the German version of the Transplant Effects Questionnaire (TxEQ-D), which measures the emotional response to an organ transplantation, has the same factorial structure as the English original version and b) whether the psychometric properties as well as the correlations with the scales of the SF-36 are comparable.

Methods: The questionnaire TxEQ was translated into German and filled out by 370 heart, lunge, liver and kidney transplant patients. Subsequently, factor and item analyses were conducted. The SF-36 was used to test validity.

Results: The TxEQ-D has the same factorial structure as the English version as well as comparable psychometric properties. The TxEQ-D factor "worry about transplant" shows the highest correlations with the 10 scales of the SF-36, the lowest correlations with the 10 scales of the SF-36 scales are found for the factor "adherence".

Conclusions: The TxEQ-D is a useful screening instrument in psychosomatic research and in the psychotherapy practice to detect patients with problematic emotional responses to an organ transplantation.
