In this study we developed a theory grounded in data from women who continued healthy eating behaviors after a weight management program. Participant recruitment was guided by theoretical sampling strategies for focus groups and individual interviews. Inclusion criteria were: African American or Caucasian women aged 30+ who lost [greater than or equal to] 5% of their body weight in a weight management program [greater than or equal to] year ago. Participants [greater than or equal to] 5% below their baseline weight were maintainers (n = 9); those above were non-maintainers (n = 14). We asked open-ended questions regarding healthy eating behaviors. The systematic design is described in detail, including categories from open coding, connection during axial coding, and integration into a theory, labeled Commitment to Healthy Eating, during selective coding. Procedures for establishing credibility are also included. (Contains 1 table, 1 figure and 1 footnote.)
