Abstract:
Anxiety is a behavior related to psychosomatic diseases. Through an evaluation of the iris it is possible to determine personality traits and to intervene early to refrain any non-adaptive behavior from causing psychosomatic diseases. Contraction furrows suggest a predisposition to anxiety. This study aimed to verify the correlation of contraction furrows in the iris with the state-trait anxiety inventory (STAI). This study was approved by the Research Ethics Committee of the University of São Paulo, School of Nursing, and performed with 62 teachers and employees at the Center of Health Science of the Zerbine Foundation (CeFACS), from May to July, 2010. The Spearman coefficient showed a positive and statistically significant correlation between the STAI score and the quantity of contraction furrows. This suggests that these signs indicate a predisposition to anxiety. With the early identification of this behavior we have chances to reduce the development of the disease.
