title: Intrinsic and extrinsic motivation and intention to breast-feed.
abstract: OBJECTIVE
  To examine the feasibility of using the cognitive evaluation theory to examine pregnant women's intention to breast-feed.
  
  
  METHODS
  A questionnaire designed to measure intrinsic and extrinsic motivation was administered to 228 pregnant women.
  
  
  RESULTS
  Results provide evidence for reliability and validity of the revised instrument in this population. A factor analysis suggests the instrument measures 2 types of intrinsic motivation, one type of extrinsic motivation, and motivation related to the baby. The instrument distinguished differences in motivation between women who intend to breast-feed and those who intend to formula feed.
  
  
  CONCLUSIONS
  This study helps elucidate motivational factors involved in infant-feeding decisions.
