A Study of Psychological Distress in Respect to Different Blood Types

The main purpose of this research was to find out the different levels of Psychological distress and the association between four blood types and depression, anxiety and stress. The Depression Anxiety and Stress Scale (DASS), developed by Lovibond and Lovibond (1995) was applied to test the research questions. The study revealed that the individuals with AB and O blood types typically experience severe to moderate depression, whereas those with A and B blood types often have mild or normal levels of depression. The Chi-Square analysis indicates that blood type A is primarily associated with moderate anxiety, B with extremely severe anxiety, AB with severe anxiety, and O with mild anxiety. Regarding stress, blood type A is predominantly associated with mild stress levels, B with extremely severe stress, AB with severe stress, and O with moderate, mild, or normal stress levels.
