Abstract
OBJECTIVES: The "Fragebogen zur Sozialen Integration (FSI)" is the German adaption of the "Social Adjustment Scale (SAS-SR)". So far, there is no validation of the FSI with regard to patients with cancer. METHODS: The scales leisure time, relatives and partnership of the FSI were test-statistically analyzed in hemato-oncological patients. Concordant validity was examined referring to the German version of the "Social Support Questionnaire (F-Sozu)" and one scale of the "EORTC QLQ-C30". RESULTS: In N = 184 participants, we observed in 1% - 20% missing values for several items. Ceiling effects could be observed for the scales relatives (1.22-2.20), whereby for the scales leisure time (1.27-2.95) and partnership (1.51-3.91) the range was substantially higher. Internal consistency averaged about 0.75 (leisure time, partnership), respectively, 0.69 (relatives). Analyses for validity showed values of -0.23 to -0.50 (F-Sozu) as well as -0.29 to -0.40 (EORTC QLQ-C30), respectively. CONCLUSION: The FSI is a reliable questionnaire to assess social adjustment within hemato-oncological cancer patients. However, psychometric properties in previous studies with psychosomatic patients were better. The high amount of missing values on several items in our study suggests a partial revision of the this instrument would be advisable for use in oncology.
