The Relationship Between Public Speaking Performance, Interpersonal Factors, and Endocrine and Inflammatory Response To Stress Pubblico
Whitehead, Aaron Edward (2013)
Abstract
Introduction: While physiological measures as well as
self-report have been widely employed to examine what individual
characteristics alter one's response to acute laboratory
psychosocial stress challenges, measures of overt behavior have
less commonly been utilized. Measures of overt behaviors, like
physiological measures, may reveal important information about
anxiety that is otherwise suppressed during
self-report.
Methods: Speech form during a standardized acute psychosocial stress challenge (the Trier Social Stress Test [TSST]) was analyzed for speech errors using criteria previously outlined by Lewin et al., (1996). Speech errors were quantified as verbal errors (i.e. correlations, repetitions) as well as procrastinating verbalizations. Speech form was then related to subjective distress responses to the TSST (Profile of Mood States [POMS]), endocrine (cortisol) and inflammatory (interleukin [IL]-6) responses to the TSST as well as to trait features including depression (Beck Depression Inventory [BDI]) and anxiety (Beck Anxiety Inventory [BAI]), and state features including perceived life stress (Perceived Stress Scale [PSS]) and life satisfaction (Satisfaction With Life Scale [SWLS]).
Results: Speech errors were not found to be associated with changes in circulating concentrations of cortisol or IL-6 as a result of challenge with the TSST. However, speech errors were found to be positively associated with change in POMS total score from before to immediately following the TSST. BDI, PSS, and SWLS scores were found to be associated with increased speech errors during the task. No significant relationship was found between speech errors and BAI scores.
Conclusion: These results suggest that measures of speech performance during an acute laboratory psychosocial stressor may be related to subjective distress experience during the same challenge, as well as depression features, perceived life stress, and life satisfaction.
