Cognitive Behavioral Intervention for Seasickness

摘要

The principal aim of this study was to assess the effectiveness of a cognitive behavioral intervention for seasickness. Specifically, this study examined the effect of an intervention that was designed to increase self- efficacy and self-control beliefs in trainees preparing for sea duty. Literature review indicated that successful psychological interventions for motion sickness generally include a cognitive component aimed at increasing subjects' confidence in dealing with motion sickness. In studies of seasickness, cognitive manipulations that increase self-efficacy beliefs and self-control initiative have been successful. This study examined the effect of a cognitive intervention in reducing symptoms of seasickness in 247 US Naval Academy midshipmen taking part in summer sea training (14 day sea cruise). Participants were grouped by squadron and randomly assigned to intervention and control conditions. The principle hypothesis of the study was that the cognitive intervention group would experience fewer symptoms of seasickness compared to the control group. Self-efficacy, self-control and state anxiety were expected to mediate outcomes from the intervention. Trait anxiety, body vigilance, anxiety sensitivity and history of motion sickness were assessed as possible predictors of seasickness occurrence (independent of intervention effects). Outcome was measured in terms of symptom frequency and intensity, and performance ratings made by supervisors.
