title: Factors affecting osteoarthritis patients' self-reported goal-directed drug information-seeking behaviors after exposure to direct-to-consumer advertising from physicians and the internet.
abstract: OBJECTIVE
  The objective of this study was to investigate appraisal of means (ie, self-efficacy, outcome expectancy, and affect) in predicting patients' goal-directed behaviors of direct-to-consumer advertising (DTCA)-prompted drug-information search from physicians and the internet.
  
  
  METHODS
  One thousand patients were randomly selected from a nationwide sample frame of 3000 osteoarthritis patients. A self-administered survey assessed exposure to DTCA, drug-information search as goal, self-efficacy, outcome expectancy, affect, and osteoarthritis pain. After 6 weeks, another survey measured the behavior of drug-information search for respondents to the first survey. Study subjects were those who were exposed to DTCA in the previous month, and who set drug-information search as their goal. For each information source, a multiple regression analysis was conducted in which drug-information search was the dependent variable, and self-efficacy, outcome expectancy, affect, and osteoarthritis pain were the independent variables.
  
  
  RESULTS
  Among 454 patients who were exposed to DTCA, 174 patients set drug-information search as their goal and were the study subjects. The regression for physicians was not statistically significant. The regression for the internet was significant, accounting for 15% of behavior variance. Self-efficacy was a strong predictor of goal-directed drug-information search from the internet.
  
  
  CONCLUSIONS
  Appraisal of means was useful to predict the goal-directed behavior of DTCA-prompted drug-information search from the internet. For patients who set drug-information search as a goal, actions to promote drug-information search from the internet need to focus on self-efficacy.
