title: Clinical and psychosocial variables associated with behavioral intentions to undergo surveillance endoscopy.
abstract: BACKGROUND
  Many patients with Barrett's esophagus do not adhere to guideline-recommended endoscopic surveillance. Among patient factors related to cancer prevention behaviors, patients' stated behavioral intention is a strong predictor of behavior performance. Little is known about the patient factors associated with having a strong behavioral intention to pursue surveillance endoscopy. This study explores the association of clinical and psychosocial variables and behavioral intention to pursue surveillance endoscopy among patients with Barrett's Esophagus and no or low-grade dysplasia.
  
  
  METHODS
  Potential subjects were screened using electronic medical records of a regional Veterans Affairs Medical Center and a pathologically confirmed Barrett's esophagus registry. Eligible participants were recruited by a mailer or phone call and completed a questionnaire to measure six distinct psychosocial factors, their behavioral intention to undergo surveillance endoscopy, and various demographic and clinical variables. Univariate and multivariate linear regression identified the relation of behavioral intention with each of six psychosocial variables.
  
  
  RESULTS
  One-hundred and one subjects consented and returned surveys. The analytical sample for this study consists of the 94% of surveys with complete responses to the behavior intention items. Three of the six psychosocial domains were statistically significant predictors of intention in both univariate and adjusted univariate analysis (salience/coherence β = 0.59, 95% CI = 0.45-0.76, P <0.01; self-efficacy β = 0.30, 95% CI = 0.10-0.51, P <0.01; and social influence β = 0.20, 95% CI = 0.08-0.33, P <0.01). In a multivariate analysis only salience/coherence (β = 0.65, 95% CI = 0.42-0.88, P <0.01) remained statistically significant predictor of intention.
  
  
  CONCLUSIONS
  This study established the validity of a scale to measure psychosocial variables associated with behavioral intentions to undergo surveillance endoscopy. Results demonstrate the importance of assessing self-efficacy, social influences, and bottom-line belief in the value of surveillance endoscopy when evaluating a patient's likelihood of completing surveillance endoscopy.
