Abstract: Objectives: The "Dresdner Körperbildfragebogen" (DKB-35; Thiel, 2007) was psychometrically evaluated in a non-clinical sample (n = 349). Methods: Statistical analyses with SPSS/PASW involved item- and scale distribution as well as reliability- and validity analyses. Results: First, reformulation of some of the items of the DKB-35 should be considered. Second, the scale structure of the DKB-35 was approximately replicated. Third, the internal consistency of the scales varied between low α = 0.76 (body contact) and high α = 0.91 (sexual satisfaction) values. Furthermore, stability over time was demonstrated for a period of seven days regarding the dimensions of the body image. Moreover, the DKB-35 was able to differentiate between underweight, normal weight, overweight and obese individuals. Correlations with questionnaires measuring psychological stress, interpersonal problems, stress experiences and social support demonstrated construct-validity. Conclusion: The development of the DKB-35 does not appear fully completed. However, this study confirmed the quality of the questionnaire regarding reliability and validity. Following a comprehensive standardisation and evaluation in specific samples, the DKB-35 could serve as a routine multidimensional instrument of the body image and its disorders.
