Validation of Screening Questions for XXXX .

@entity1 @entity7804 @entity392 @entity158
UNASSIGNED: Background. We investigated the validity of the two @entity7804 items of the @entity392 ( @entity392 ) from the @entity392 ( @entity392 ) database by comparing them with the German @entity7804 questionnaire G  F. Methods. We investigated the association of the G  F with the @entity392 screening questions for both the sum score and the single items with correlation, contrast, principal component, and discriminant analysis in a sample of 161 @entity1 with chronic @entity392 . Results. @entity392 items and the G  F total score were significantly associated with a special focus on fear and @entity158 related @entity7804 . Factor analysis of the G  F revealed the three factors "fear and @entity158 related @entity7804 ," "hearing related problems," and "problems in quality of life." A discriminant analysis showed a sensitivity of 64% and a specificity of 71% of the @entity392 items for the establishment of @entity392 @entity1 subgroups with and without @entity7804 . Discussion. Both @entity7804 @entity392 items can serve as screening questions with respect to self-reported @entity7804 in chronic @entity392 with a specific focus on fear and @entity158 related @entity7804 . However, the multiple dimensions of @entity7804 should be considered for diagnosis and treatment in both scientific and clinical contexts.
