Abstract
The association between mood and plasma testosterone was investigated. Every second day for 2 months, a Multiple Affect Adjective Checklist was filled out by 20 young men. Blood samples taken at the same time were analyzed for testosterone concentration. Relationships between hostility, anxiety, and depression and plasma testosterone levels were tested both within and across individuals. Intrasubject correlation coefficients between affects and hormone were fairly evenly distributed between positive and negative values, some significant on either side. Intersubject correlation coefficients were all positivie. Between depression and testosterone, the correlation was significant only at the 10% level; between the other two affects and testosterone, the correlations were not significant.
