Preparation for a stressful medical procedure: Effect of amount of stimulus preexposure and coping style

Journal Article

Studied anxiety during the stressful medical procedure of endoscopy as a function of the number of prior viewings of an explicit preparation videotape and of repression-sensitization coping style. 60 naive patients aged 22-80 yrs viewed a videotaped endoscopy either 0, 1, or 3 times. Dependent measures included heart rate, behavioral ratings, tranquilizer required, and self-report (State-Trait Anxiety Inventory and Post-Endoscopy Interview Schedule). On each dependent measure, 3 viewings generally resulted in the least distress; 1, more distress; and 0, the most distress. Most comparisons reached significance. Results are interpreted as resulting from extinction and/or habituation of anxiety. The repression-sensitization factor interacted with heart rate change. Sensitizers showed a monotonic decrease in heart rate as a function of number of tape exposures. Repressors showed an inverted-U-shaped function, with 1 viewing producing the highest heart rate; this is interpreted as resulting from a disruption of repressing defenses by 1 tape exposure followed by extinction of fear by 3 exposures.
