Factor analysis finds four factors with unrotated eigenvalues greater than 1.0. Oblique (promax) rotation shows that the first factor is similar to what previous studies referred to as a fear factor (Krueger, 1999; Watson, 2005), with high loadings for panic and phobias (.67-.79).(Table 1) The second factor represents what previous studies referred to as a distress factor, including depression, generalized anxiety, post-traumatic stress, and separation anxiety disorders (.51-.87). The third factor represents behavior disorders (.49-.94) and the fourth represents alcohol-drug disorders (.89-.91), although conduct disorder (.44) and bipolar disorder (.40) also have elevated loadings. Disorders in the fear factor are the most common (26.1%), followed by distress (25.4%), behavior (22.7%), and substance (11.4%) disorders. The factors are all significantly correlated with each other, from a high Pearson correlation of .44 between fear and distress disorders to a low correlation of .16 between fear and substance disorders.
