Background: Among other features, the Berlin Study on environmentally related disorders assessed the environmental worry (EW) of environmental patients and clinical controls (outpatients of family doctors, melanoma aftercare patients, inpatients of a psychosomatic clinic). The study presented here investigates whether environmental patients differ from controls in respect to environmental worry (or components thereof).
Methods: The sum score of the environmental worry scale (= Skala für Umweltbesorgnis, SUB) is a measure for the overall EW. A principle component analysis (PCA) was used to extract principle components (PC) which represented different aspects of EW.
Results: According to the sum score of SUB no differences between environmental patients and controls could be found in regard to the overall EW. There were, however, remarkable differences between the groups when the PCs were considered. The 'general EW' (PC1), not referring to the own person, is highly significantly lower for environmental patients than for clinical controls, whilst the 'self-centered health-related EW' (PC2), referring to the own person, is significantly or even highly significantly stronger. For the third PC ('general health-related EW') no differences could be found. During the past 10 years the SUB sum score declined remarkable, but the decline observed for environmental patients was stronger than that for 'healthy' persons or other than environmental patients which lead to the present equality.
Discussion and conclusions: We discuss possible reasons for the decline of environmental worry. When assessing environmental worry by means of the environmental worry scale (SUB) it should be differentiated between 'general EW' and 'self-centered healthrelated EW'. |
