  ABSTRACT: The evaluation of quality of life is an established criterion for evaluation of therapeutic measures. Starting from the English-speaking area a great number of different patient-based outcomes measures were developed to specifically question disorders of the musculoskeletal system and the results of treatment. Because of the lack of a German measurement tool for patients with rotator cuff disease the translation and the psychometric testing following international guidelines of the 34-item, multidimensional, English Rotator Cuff Quality-of-Life Measure (RC-QOL) was undertaken. Reliability (test-retest reliability, internal consistency), validity, practicability and acceptance of the German version of the RC-QOL were tested by 102 patients with an impingement syndrome after translation and cross-culture adaptation of the English original questionnaire. In addition, the SF-36, the Constant and UCLA scores were evaluated. Between the evaluations there was no significant difference; the Pearson correlation coefficient was 0.89 for the test-retest reliability. The internal consistency showed a high homogeneity with a Cronbach Alpha-coefficient of 0.98. A Pearson correlation coefficient between 0.67-0.76 registered a high correlation with the physical subscales of the SF-36, the Constant and the UCLA scores. The mean time required for completing the RC-QOL was 12 minutes; mean time required for evaluation was 10 minutes. The questionnaire was incompletely answered by 16 patients (15.6%). A total of 120 items (3.5%) were left unanswered. After successful translation and psychometric testing of the German version of the Rotator Cuff Quality-of-Life Measure (RC-QOL) a multidimensional measurement tool for evaluating the quality of life of German-speaking patients with pathology of the rotator cuff is available.

  ABSTRACT: Die Beurteilung der Lebensqualitt eines Patienten stellt ein zunehmendes Kriterium zur Bewertung von Behandlungsverfahren dar. Der vom angloamerikanischen Raum ausgehende Prozess fhrte zur Entwicklung einer Vielzahl verschiedener Messinstrumente, die auch spezifisch Erkrankungen des muskuloskelettalen Apparates und deren Therapieverlauf evaluieren. Mangels eines deutschsprachigen Messinstrumentes fr Patienten mit pathologischen Vernderungen der Rotatorenmanschette, soll die bersetzung und psychometrische Austestung des 34-Item umfassenden, multidimensionalen, englischsprachigen Rotator Cuff Quality-of-Life Measure (RC-QOL) nach internationalen Richtlinien erfolgen.Nach bersetzung und Cross-Culture-Adaptation des englischen Originals wurde die Reliabilitt (Test-Retest-Reliabilitt, interne Konsistenz), die Validitt, die Praktikabilitt und Akzeptanz der deutschen Version des RCQOL an 102 Patienten mit einer Impingementsymptomatik geprft. Zustzlich wurden der SF-36, der Constant- und der UCLA-Score an allen Patienten erhoben.Der Pearson-Korrelationskoeffizient war mit 0,89 ausreichend hoch fr die Test-Retest-Reliabilitt, zwischen beiden Erhebungen zeigte sich kein signifikanter Unterschied. Die interne Konsistenz erbrachte mit einem Cronbach-Alpha-Koeffizienten von 0,98 eine hohe Homogenitt. Der Pearson-Korrelationskoeffizient wies mit Werten von 0,67–0,76 eine hohe Korrelation mit den physischen Subskalen des SF-36, dem Constant- und UCLA-Score auf. Die durchschnittliche Zeit zur Beantwortung des RC-QOL lag bei 12 Minuten, zur Auswertung wurden 10 Minuten bentigt. 16 Patienten (15,6%) fllten den Fragebogen unvollstndig aus, insgesamt blieben 120 Einzelfragen (3,5%) unbeantwortet.Nach erfolgreicher bersetzung und psychometrischer Austestung der deutschsprachigen Version des Rotator Cuff Quality-of-Life Measure (RC-QOL) steht nun ein multidimensionales Messinstrument zur Erhebung der Lebensqualitt von deutschsprachigen Patienten mit einer pathologischen Vernderung an der Rotatorenmanschette zur Verfgung.The evaluation of quality of life is an established criterion for evaluation of therapeutic measures.

  ABSTRACT: At the moment a specific subjective measurement tool for evaluation of German-speaking patients with a pathology of the rotator cuff is lacking. Following international guidelines, the German translation and the psychometric testing of the 21-item, multidimensional Western Ontario Rotator Cuff Index (WORC) is the aim of the study. After translation and cross-culture adaptation of the English original, the reliability, validity, practicability and the acceptance of the German version of the WORC were tested on 102 patients with an impingement syndrome. Additionally the SF-36, the Constant and UCLA score were evaluated. The Pearson correlation coefficient showed with 0.96 an excellent result for the test-retest reliability. The internal consistency showed a high homogeneity with a Cronbach alpha coefficient of 0.96. A Pearson correlation coefficient between 0.66-0.81 registered a high correlation with the physical subscales of the SF-36, the Constant and the UCLA score. The mean time required for filling out the WORC was 7.5 minutes, the mean time required for evaluation was 10 minutes. The acceptance and the understanding were very high. After successful translation and psychometric testing of the German version of the Western Ontario Rotator Cuff Index (WORC), a patient-based measurement tool for evaluating the quality of life of German-speaking patients with pathology of the rotator cuff is available.
