Examination of the relationship between patients' coping style, pregastroscopy information, and anxiety associated with gastroscopy in China was the aim of this study. A pretest, post-test, nonrandom assignment study with a two by two design was conducted. One hundred forty-five patients who underwent initial gastroscopy without sedation were classified into 2 groups on the basis of the coping style: information seekers or information avoiders using the Information Subscale of the Krantz Health Opinion Survey (KHOS-I). All participants were given standardized procedural information about gastroscopy as routine care. Half of each group was assigned to receive additional sensory information describing what sensation they would experience and how to cooperate to alleviate the discomfort. State anxiety assessed by the State Anxiety Scale of Spielberg's State-Trait Anxiety Inventory, blood pressure, and pulse were measured at enrollment and before gastroscopy. The information seekers and avoiders who received additional sensory information experienced significantly less state anxiety after the intervention. In contrast, the information seekers and avoiders who received standardized procedural information maintained their preintervention state anxiety level. Most patients reported their preference for sensory information. In conclusion, the provision of sensory information could significantly reduce patients' pregastroscopy anxiety regardless of patients' information coping style.
