Patient perceptions of blind and open weighing in treatment for eating disorders.

Little is known about patients' perceptions toward open and blind weighing for eating disorders. Upon admission to a partial hospitalization program, 35 child/adolescent patients, 55 adult patients, and 36 parents of child/adolescent patients completed questionnaires assessing attitudes toward open and blind weighing. Participants perceived blind weighing as more effective in the short term. No differences emerged on measures assessing preference, credibility, or long-term effectiveness. Relative to adults, parents preferred blind weighing, and child/adolescents perceived blind weighing as more credible. On a forced-choice question, a majority of adults, about half of children/adolescents, and a minority of parents preferred open weighing over blind weighing. There was a positive association between past treatment experience and current attitudes about weighing. Results suggest that individuals enter treatment with variable attitudes about weighing procedures for eating disorders, and may develop more favorable attitudes toward the practice they receive in treatment.
