Single-blind randomized controlled trial of an educational booklet for patients with chronic arthritis

Abstract

Consecutive new attendees at a rheumatology clinic were randomly allocated to one of three groups. All groups received routine care, but one received no other intervention. one an educational booklet on arthritis and one the booklet plus instruction from a health professional. Prior to intervention, all groups had similar knowledge, Nottingham Health Profile (NHP) and Health Assessment Questionnaire (HAQ) score. After 6 weeks, the knowledge score was significantly increased in both groups given the booklet, but not in the control group. The group instructed by a health professional showed no greater increase than the group given the booklet alone. Increased knowledge was not associated with improved clinical status and no group showed a significant change in NHP or HAQ scores. Nearly all patients said they found the booklet useful.
