Gw. Blood et al., SUBJECTIVE ANXIETY MEASUREMENTS AND CORTISOL RESPONSES IN ADULTS WHO STUTTER, Journal of speech and hearing research, 37(4), 1994, pp. 760-768
Anxiety, as measured by self-report inventories and salivary cortisol
levels, was examined in 11 males who stutter and 11 males who do not s
tutter during baseline, low stress, and high stress sessions. During t
he high stress session salivary cortisol was significantly greater in
persons who stutter than in persons who do not stutter. No significant
differences were found between the two groups on the State Anxiety In
ventory, Trait-Anxiety Inventory, or the Personal Report of Communicat
ion Apprehension. Significant differences in anxiety levels among the
baseline, low stress, and high stress sessions for both groups of subj
ects were found for the State-Anxiety Inventory. No other significant
differences or relationships were found between the two groups.
